Our trainees on the Identification Trainers for the Future project have been extremely busy since our last blog post, here's Mike Waller with an update on what they have been getting up to!

Our timetables, until now a collage of various colours, have become a very busy reality over the last two months. We got our teeth into another batch of long-anticipated ID workshops - Flowering Plants, Beetles, Flies and Earthworms. I think I speak for everyone when I say the skills and knowledge we've been passed by some of the leading scientific experts in the Museum have been rich, extensive and unique. Developing techniques to hoard as much of this golden information as possible have become paramount.

 

I've already gathered a thick stack of mixed ID keys, notes, powerpoint handouts and even the odd specimen - usually midway through the processing to go into my personal collection. Sally has taken her learning consolidation to a new level and is producing an incredible assemblage of annotated line drawings and intricate watercolours in her note book. She'll be blogging about that separately, but we're all a little jealous!

The first of these workshops was a one-day instalment of flowering plants out in the wilds of East London with Mark Spencer. We met promptly for 9.00 at Mile End tube station before heading out in the company of other trainees from a similar scheme called Wild Talent being run by the London Wildlife Trust (also funded by the HLF's Skills for the Future programme), and people who narrowly missed out on getting the traineeship during the first round. Indeed, several places have been made available on all workshops for the other 20 trainee applicants as an opportunity to maximise the skills-base across the board. It was great to see them again!

After a scorching day keying out Fabacae and crucifers, dodging cyclists and discussing the horror of path-side 'tidying', we finished in Mark's local pub for a well-earned pint. As always, Mark's casual ability to blend good science, humour and memorable anecdotes always makes for a superb time. We all very much look forward to our next sessions with him in July.

 

Next up was our very first invertebrate workshop, and what better to start with than beetles - the group within which both Katy and Anthony find their true passion. This workshop was a solid four-day stretch that began with Roger Booth taking us through the depths of beetle anatomy followed by some family keying. Max Barclay provided a two-part lecture on world beetle families that, for me, gave a fascinating insight into the truly spectacular speciation and morphological diversity of the group acoss the planet.

 

As our confidence grew, we began to use specific familiy keys to make accurate species identifications of some of the more challenging groups such as Elateridae or the 'click' beetles. Michael Geiser and Roger offered invaluable help during this process as their oceans of knowledge were repeatedly called upon.

Just as we thought we were getting to understand insects, BOOM, in swept the seemingly impenetrable order of flies - a group with unfathomable diversity! Luckily we were in very good hands as we were led through the array of sub-orders by Erica McAlister, Duncan Sivell, Zoe Adams, Daniel Whitemore and the AMC's very own Chris Raper.

 

In similar style to the beetles, we used familiy keys to start with then slowly graduated to species identifications where possible. This workshop however came with a difference and on the second day, we all met at Wimbledon Common for a day out collecting.

 

With nets, pooters and pots at the ready, we were unleased on the varied mix of heathland, pastures and oak woodlands to capture what we could. The weather couldn't have been better and gave us a golden opportunity to use collecting techniques in the field. Once back in the Museum we were then able to pin and mount our specimens for our personal collections.

Our most recent workshop went subterranean with Emma Sherlock as we dug up seemingly half of the Wildfowl & Wetlands Trusts London Wetland Centre in the pursuit of earthworms. Using our trusty spades, and encouraged with the possibility of encountering a rare species, we sampled different habitats around the reserve to gain a good range of species which we then took back to the lab for identification the following day. Emma's unbridled passion for earthworms is infections and we all developed a new-found interest to take forward.

 

 

If that wasn't enough, we all packed our walking boots and set out for our placements with the Field Studies Council where we were based at various FSC Centres scattered up and down the country.

 

During May, I made my way north to Malham Tarn, whilst Chloe took heading north to the extreme with a week at Kindrogan and Milport on the edge of the Cairngorms National Park. Meanwhile, Anthony settled at Flatford Mill in Suffolk. Sally followed the South Wales coast to Dale Fort and Katy battled her way through the winding roads of North Wales to Rhyd-y-Creau in the mists of Snowdonia.

 

The focus of each of our placements was 2-fold: to observe the identification courses each centre was running and to assist with the outdoor teaching for which the FSC is renowned. I got to observe a beginners course called 'Spring Wildflowers of the Dales' which, as you'd expect, concentrated on the botanical.

 

It was led by local botanist Judith Allinson who taught a mixture of plant structure and lineage with a good dose of field visits to observe some of the specialist plants of the stunning limestone pastures, pavements and hay meadows. Having not been to the Dales proper before, I was continually stunned by this landscape of dramatic limestone cliffs and thick green meadows chequered by moss-drenched dry stone walls where the only sounds were the melancholy warbles of distant curlews. Highlights for me were the rafts of early purple orchids, adder's-tongue ferns and a hungry peregrine attempting to snatch Lapwing chicks on the tarn shore

The second part of my stay saw a sudden shift from pupil to teacher as various school groups, ranging from 8-14 year olds, visited for day trips and longer stays. This meant hanging out with the tireless field teachers who work extremely long hours to meet the educational needs of over-excited children!

 

It was a real privilege to see the field teacher's skills in action, but equally how challenging their roles can be. Trying to deliver a range of syllabus-based content that is relevant and exciting to different age groups, whilst trying to avoid the hazards of controlling a large group of children in an unpredicatable environment is very hard indeed. These observations were echoed by the other trainees who also gained immesurably from their experiences.

 

To round off our teaching and learning, Sally, Anthony and I also got stuck into some more people engagement at Big Nature Day here at the Museum. This is a coming together of over 50 different specialist wildlife organisations from across the UK. These included the more familiar groups such as the BSBI and iSpot, but it also provided an opportunity for some of the lesser-known societies such as the Conchological Society of Great Britain and Ireland and the British Pteridological Society to get their name out there.

 

Like Lyme Regis, this was a wonderful opportunity to showcase the work of the Angela Marmont Centre while also browsing and networking with some fascinating wildlife groups. As trainees, we ran our own table providing microscopes to observe lichens and several drawers filled with UK insects and bee mimics. I also spent some of my time at the Orchid Observers stand where I helped answer questions about the project alongside Kath Castillo, Fred Rumsey and Mark Spencer.

All in all, an inspiring day, and an inspiring, and hectic couple of months! As the traineeship progresses, we're all looking forward to our next few workshops, which include Freshwater Invertebrates, Lepidoptera and Hymenoptera, as well as our short field trip down to the Isle of Purbeck before we all set sail in September for our three month curation placements at various departments around the Museum. Make sure you stay tuned for the next instalment of the Identification Trainees saga!

This month it is the turn of Katy Potts to give us an update on the progress of the trainees on the Identification Trainers for the Future project. Since Anthony's review of their first month with us the trainees have progressed onto Phase 2 of their programme, where their species identification training really starts in earnest and we've certainly been keeping them busy!

The past two months have been both exciting and enlightening in educating us about the world of biological recording and species identification. It was while I was at Plymouth University that I first discovered species identification in an invertebrate taxonomy module with the ever inspiring entomologist Peter Smithers. It was under Peter's guidance and teaching that I fell in love with the six legged insects that run our world. Moreover, it was the passion for taxonomy from Peter that inspired me to delve into this field of biology.

 

The past two months have been fantastic. We are currently in Phase 2 of our programme where the core identification workshops, Field Studies Council placements and project work are taking place.

 

We have been welcomed into the Angela Marmont Centre for UK Biodiversity (AMC) in the warmest way possible. After we settled in we were each given a role in one of five citizen science projects: The Microverse (me), Orchid Observers (Mike Waller), The Urban Tree Survey (Chloe Rose), The Big Seaweed Search (Anthony Roach) and The Bluebell Survey (Sally Hyslop). You might have seen posts from some of us on about our projects on the Citizen Science blog.

 

My role was to work on the Microverse project, which looks at discovering what species of micro-organisms live on buildings in the UK and what environmental factors affect their diversity. In this project, schools are asked to swab buildings made of different materials. They then send the DNA to us at the Museum for analysis. My role in this project is to carry out the DNA extraction in the microbiology labs and then help collate the results to send back out to the schools. Whilst working on this project, I have gained invaluable experience in current methodologies used for DNA extraction, something I was keen to learn but never anticipated doing through the traineeship!

 

My personal highlight of the traineeship is the identification workshops, which began in April with a two day Bryophyte ID course with Dr Fred Rumsey. During this course we looked at the anatomy of bryophytes, learning about their distributions and status as a group in the UK. We used microscopy to become familiar with a wide selection of species, focusing on the features that define their identification. There was also a field trip organised to Burnham Beeches where we observed a range of bryophytes in the field, from sphagnum mosses to the rare Zygodon forseri (knothole moss).

The second identification workshop was on Lichens with Lichenologist Holger Thues. To begin this course we explored the biology of lichens, their anatomy and distributions in the UK. We then went on a field trip to Hampstead Heath to look at a range of lichens that are present in this area, some of which are important indicators of pollution levels.

 

Personally, I found this an eye opening experience as I come from a part of Devon that is not far from Dartmoor, where I have spent many days walking along the River Dart. Along the riverside and some of the woodlands (such as Whistmans Wood) there is an abundance of lichen species, many growing to be large specimens due to the quality of the habitat. Seeing the effect that pollution has on the growth forms of the same species of lichen in London was very interesting.

 

When back in the museum, we spent some time in the cryptogrammic herbarium where we used a range of keys to begin learning lichen taxonomy and microscopy for identification. This included using chemical tests and cross-section microscopy to aid species identifications.

As the weather begins to warm and the field season begins, many different wildlife groups are emerging and buzzing around. This ignited the desire in all of us to learn field survey techniques. As part of our environmental consulancy module we looked at methods for surveying different groups of wildlife. We were lucky enough to have the chance to survey newts in the Wildlife Garden here at the Museum. Steph West (the Project Manager for the ID Trainers project who has previously worked as an ecological consultant) supervised us while we undertook dusk and dawn newt surveys where we learnt key methods for newt trapping and releases as well has how to identifiy the different species.

During the sunnier days in London when we have some free time we are able to retreat into the Wildlife Garden to observe and collect insects. The garden is very diverse with a wide range of UK habitats that support a number of different wildlife groups. This valuable resource allows us to collect specimens and gain experience in identifying them. We are then able to incorporate them into our own collections which we can use as an identification reference. When out in the field we are also encouraged to collect specimens to support our work in identification. I have recently been working on identifying a wood ant I collected whilst out on a field trip:

There are many more workshops and events to look forward to over the next month: Coleoptera, Flowering Plants, Dipetera and Earthworms are all coming up. For the last part of May however we are all on placements with the Field Studies Council for one week. I will be heading to the FSC centre in Rhyd-y-creuau in Snowdonia at the end of May assisting on courses on tree identification, arctic alpine flowers and a school Geography field trip.

 

Thank you Katy! Next month we'll be getting an update from Mike Waller on how those placements have gone, as well as some of the workshops and events that the trainees have been working on.

Our trainees on the Identification Trainers for the Future project have now finished Phase 1 of their programme and are busy working on Phase 2. During Phase 1 they had the opportunity for a fantastic introduction to the work and collections of the Museum as well as an introduction to biological recording and collections principles.

 

In Phase 2 they will be focussing more on their identification skills through a series of workshops as well as getting involved in the work of the Angela Marmont Centre for UK Biodiversity. In this blog post Anthony gives an overview of their experiences in Phase 1 as well as looking forward to some of the work he will be doing in Phase 2.

 

Prior to starting on the ID Trainers for the Future programme, I have already been lucky enough to work at the Museum as a Science Educator for over 4 years and, through my new role as a trainee in the Angela Marmont Centre for UK Biodiversity, I have been given the opportunity to develop new skills, gain experience of practical field work and wildlife recording. Most of all, I have glimpsed the wonderful - exploring the Museum's scientifically, historically and culturally significant collections behind the scenes.

I couldn't have asked for a better welcome in the AMC, and the programme for the first phase has been a thoroughly engaging mix of professional development and collections-based training. Besides learning the craft of pinning and identifying insects, I have recieved training on organising field work, field work first aid and how to handle and use biological data with expertise from the National Biodiversity Network.

 

Online recording systems such as iSpot and iRecord encourage the public to share and record their wildlife sightings and, through a practical session with Martin Harvey from the Open University, I created a working identification key to Damselflies, one of my favourite insect groups. You can use the identification keys on iSpot to identify anything from butterflies to lichens, so go on and have a go yourself at www.ispotnature.org.

 

With such lovely Spring weather recently we've been let loose to collect and record wildlfie from the Museum's own Wildlife Garden which is currently buzzing with insects and the melodies of British songbirds. Late night newt surveying in the Garden was a real highlight so far. The Garden is a haven for thousands of British plants and animals and demonstrates wildlife conservation in the inner city. Over 2,000 species have been identified in the Garden since it opened in 1995.

The AMC works hard to encourage people to become 'citizen scientists' to explore, identify and record the wildlife they see, and this plays a key role in the monitoring of and recording of UK biodiversity. This helps researchers see how species are adapting with climate change and human activity. There are several brilliant Citizen Science projects that you yourself can get involved with, the most recent from the Museum being The Microverse and Orchid Observers. If you want to find out more and see new projects when they come on stream, keep an eye on the Take Part section of the website.

 

Part of my traineeship will involve championing a Citizen Science project. Growing up near the sea in Devon I have a passion for exploring marine life so I was delighted to find out that I'll be working as part of a team to enhance the Museum's Big Seaweed Search. The UK's coast is rich in seaweeds because of its geographical position and warming by the gulf stream, which means it is in a perfect 'golidlocks' zone.

 

An astounding 650 seaweed species can be found off the UK coastline and according to Professor Juliet Brodie, an expert on seaweeds at the Museum, seaweed coverage is so great that they are as abundant as the entire broadleaf forests combined. Seaweeds - like plants on land - photosynthesise; turning the sun's energy into food, removing carbon dioxide and producing oxygen. Seaweeds therefore play a vital role in the functioning of the marine environment.

 

The Big Seaweed Search was launched in 2009 and we aim to inform scientific research by allowing the public to record and identify seaweeds that they find. By mapping the national distribution of 12 seaweed species, we hope to see changes over time, perhaps in response to climate change, or the spread of non-native species. With the weather and tides at this time of year it's perfect for exploring rock pools, so download our survey and join our Big Seaweed Search!

A team of Museum scientists and volunteers visited Slapton Ley Nature Reserve between 21-25 July to sample invertebrates from a variety of habitats. Rachel Clark writes about their final day in the field.


25 July 2014

 

Today was the last day of sampling and we all loved it! Unfortunately Sara had to leave today, so we took the final photograph of us all together before we set off for sampling.

Every evening this week we've been preparing the specimens we collected back at the field centre, and it's fiddly work!

 

The new age of deoxyribonucleic acid (DNA)

 

Some of the specimens collected during our fieldwork are destined for the Museum’s new Molecular Collections Facility (MRF), where they will be stored in liquid nitrogen at −150 °C to form a collection that can be used by scientists worldwide who want to study the DNA and other cellular contents of the species in question.

 

Over three evenings, after our lovely cooked meal served by Shaun from the FSC, two groups of four carefully collected tissue samples from freshly killed specimens.

 

The sample tissue (often the legs) were put into special small plastic vials then placed into liquid nitrogen vapour in a dry shipper, which freezes and preserves them.

 

img2-700.jpg

Left: the small vials which contain tissue samples. Right: a dry shipper with nitrogen vapour inside.

 

In total we spent 49.5 person-hours over three days preparing the samples from 220 specimens, each sample taking on average 14 minutes to process. We tried to ensure that we only collected a maximum of two of each species - all being larger invertebrates (flies, grasshoppers, wasps, spiders etc).

 

Our last site!

 

While some enjoyed sweeping, pootering and collecting butterflies, two of us (Miranda and I) went in search for a new site on the lake to put down yellow pan traps. We ended up on the edge of Slapton village - a four-mile round trip!

We did get some amazing views and got to sample right in the middle of Slapton’s Swamp Fen, which is something we would not have achieved! The photograph above shows just how big the Ley is: miles!

 

Our last Supper


In the evening we headed off to our last dinner together before we packed up to head home. This was held in the main FSC centre in Slapton.

We would like to say a massive thank you for the staff that looked after our stomachs during our time in Slapton, and particularly Shaun who was there every day serving us breakfast and dinner!

 

Thank you for reading - I hope you have enjoyed our blogging!

Goodbye beautiful Slapton!

A team of Museum scientists and volunteers visited Slapton Ley Nature Reserve between 21-25 July to sample invertebrates from a variety of habitats. Rachel Clark writes about their second day in the field, including the range of traps they use to collect insects.


For the last two nights we have been putting out Ryan’s light trap. The trap runs all night and collects invertebrates such as moths, flies, beetles and wasps, which are especially attracted to the bright light - with a high ultraviolet component it is much more powerful than a household light bulb.

 

You can pooter specimens from around the trap while it is on, but you can also leave the insects in the trap overnight and take a look in the morning.

 

img1-700.jpg

Ryan and Thomas looking at what is flying around the light trap.

 

During our moth-trapping we collected a range of species, including Poplar and elephant hawk-moths, rosy footman, buff-tip, common footman, drinker moth and magpie moth... to name a few.

 

img2700.jpg

Left to right; buff-tip, rosy footman and poplar hawk-moth which were found in the light trap.

 

We also used a method known as sweeping, which as the name suggests is sweeping a net in a figure-of-eight through vegetation. The net catches the invertebrates and they can then be pootered out of the net bag.

 

img3700.jpg

Jan provided an excellent demonstration for all of us on our first day of sampling; we are all now brilliant at sweeping in a figure-of-eight!

 

Later on some of us went to great lengths to collect some samples, including taking a paddle in the lake, which contains leeches!

With that I will leave you with a beautiful scenic picture from the Ley!

A team of Museum scientists and volunteers visited Slapton Ley Nature Reserve between 21-25 July to sample invertebrates from a variety of habitats. Volunteer Rachel Clark reports back on their first day in the field.

 

Our first day of fieldwork mainly focused on a range of microhabitats in Slapton Woods, which is a short 10 minute walk from our base camp (Start Bay Centre).

 

Slapton Woods is ancient woodland located on the edge of Slapton Ley Nature Reserve, inland from the lake and the sea. The woodland has been around so long that is it is mentioned in the Domesday Book. Before the Field Studies Council (FSC) started to maintain the woodland (which they do only for public safety), it was largely unmanaged.

 

img1.jpgAnd so our first day of collecting started, deep in the amazing ancient woodland of Slapton Woods.

 

Now personally at this moment I felt like I was walking in the footsteps of great biologists such as Alfred Russel Wallace, Charles Darwin, and Henry Walter Bates... there are so many! I was so excited I could have danced through the woods. Raring to go with my backpack, pooter (that’s a suction device) and net, I caught up with everyone and we began to sample.

 

Working with creepy crawlies of the soil


Now this is an area which I know a lot more about, the sampling of invertebrates in the leaf litter and soil. Before we had a chance to get our bearings in the woods, Miranda, Georgie, Beau and myself got to work on some rotting logs.

 

img2.jpgBeau searching under some rotting logs for some good specimens for us to collect.

 

We were looking for groups like isopods (woodlice) and myriapods (centipedes and millipedes). This is done by opening up the rotting wood to expose the species which have burrowed into the wood.

 

It's all about the unknown - Malaise traps and yellow pan traps


So today, after a good few years sorting Malaise trap specimens in the Museum’s Soil Biodiversity lab, I finally got to see how Malaise traps work, which for me was really useful, as it means I can understand how the specimens were collected. 

 

img3.jpg

Thomas putting the final peg in the Malaise trap, a device that captures winged insects.

 

Malaise traps collect species of insects which fly such as Diptera (flies) and Hymenoptera (bees and wasps). They work by allowing the insects to fly under a tented area. They hit the netting that runs down the middle of the trap and then fall to the floor or hang on the netting. All winged insects after falling to the floor want to fly or climb upwards The Malaise trap directs them up towards the highest point where there is a funnel leading into to a pot containing ethanol – which quickly kills them.

 

We will be keeping our Malaise traps up until Thursday evening, when we will take them down and hopefully have an amazing bounty which will take very many hours to sort to order (Diptera, Hymenoptera etc).

 

What we did after we finished sampling for the day

 

After all the excitement and seriousness of sampling in the heat all day, we all have to find a way to relax and unwind… my personal favourite for celebrating a first successful day of sampling is to jump into the sea… fully clothed!

 

img4.jpgGoing, going, gone! Running in to the clear beautiful sea at Slapton Beach… yes, fully clothed!

Moth traps and sweep net collecting in the next blog piece, so stay tuned.

A team of Museum scientists and volunteers are in Slapton Ley Nature Reserve this week to sample invertebrates from a variety of habitats. Volunteer Rachel Clark reports back on their first day and plans for the week ahead.

 

Day one - the road to Slapton


An early start was made by all ten of us today to arrive at the Museum nice and early. Before 10am it's still a place buzzing with activity as scientists work and front-of-house and retail staff prepare for some of the 4 million people who come through our doors into the Museum.

 

Soon enough we were leaving London behind and heading off for the sunny coasts of Devon and our field site.

 

All about Slapton Ley Nature Reserve


Slapton Ley Nature Reserve is in Devon, near Dartmouth in the South West of England. The reserve is an area of biodiversity importance as it is a designated SSSI (Site of Special Scientific Interest) with a rich coastal heritage. The lake in the nature reserve is separated from the sea by a thin band of land, with a lovely beach too!

 

With this in mind and the recent headlines during the winter, sampling places like Slapton Ley Nature Reserve is more important than ever as sooner rather than later the environment will be claimed by the sea.

 

Photo-one700.jpg

A view of the Slapton Ley Nature Reserve to the right showing the size of the lake and the surrounding woodland and cliffs (some of which we will survey this week), and the gorgeous blue sea to the left.


Slapton Ley Nature Reserve has been studied well by scientists in certain areas such as bats and birds, but the invertebrates in the area are under-recorded. Jan Beccaloni found this out earlier in the year and believed it was time to do something about it!

 

Why and what we're sampling

 

We are sampling for collections enhancement and to provide species records to the Fields Studies Council (FSC). The habitats we will be sampling are a range of natural and semi-natural habitats, including woodland, cliffs, grassland, open water and banks.

 

The invertebrates we are collecting include:

  • Arachnids (spiders and their relatives)
  • Hymenoptera (ants, bees and wasps)
  • Lepidoptera (butterflies and moths)
  • Diptera (flies)
  • Orthoptera (grasshoppers and crickets)
  • Isopoda (woodlice)
  • Myriapods (millipedes and centipedes)

 

Now the serious explaining is over, time for the fun of the adventure! 

 

The long journey


First I must say a big thank you to Jan Beccaloni for driving us down to Slapton, Thomas our Hymenoptera specialist for driving down the bags and equipment in his amazing 40-year-old Land Rover, and last but not least Georgie for directing us.  

 

photo-two700.jpg

I personally tried to use the time to catch up on some podcasts on my iPhone which are over a year old, including one on Alfred Russel Wallace and the Birds of Paradise... I fell asleep twice! It was a 8 hour drive, though we all had a brilliant laugh in the mini bus throughout the day and got to know each other.

We passed one famous landmark, Stonehenge, very slowly which gave everyone a chance to take photos and we also passed some impressive fields with what looked to be hundreds of bales waiting to be taken into storage. We finally arrived in Slapton at our base camp of Start Bay FSC Centre at 19:00 (ish) hours with a lovely meal waiting for us ready prepared by the amazing staff at Slapton.

Some of us (myself included) were so eager to start collecting we set up a moth trap before heading off to bed. Well, that was the plan, some of us stayed up until gone past midnight looking at our catch. We plan to set it up tomorrow night and will write about it in a following post.

 

Hope you have enjoyed the excitement of our long journey! Bigger and better things to come!

 

Thank you for reading

After filling our water tanks and having breakfast, the Halton left Bergen harbor for our first diving site in Vatlestraumen on Sunday morning.

 

Leaving Bergen.JPGLeaving Bergen on Sunday morning.

 

This location is of interest to the bryozoan team because a species list was done in the area by Professor John Ryland (University of Swansea) back in the late 1950s. After dive checks are completed the bryozoan team jumps in.

As the Halton circles, waiting for the divers the return to the surface, the Norwegian coastguard arrives and asks us to move from the area as the police are undertaking a missing persons search. With bryozoans and rocks on board, the days dive plan is hastily revised and we head for Åskenset, a short steam away.

 

The horse mussel team, which consists of Dr William (Bill) Sanderson, Prof Hamish Mair and Rebecca Grieves from Heriot Watt University, are looking for maerl (coralline red algae) and horse mussel beds as part of their biogenic reef project.

After half an hour down, the divers come to the surface – it has proved unsuccessful and we move on. After a 2 hour steam through some narrow fjordic passages, we arrive in Herdlefjorden at a site commonly known as the Shark Wall. This vertical wall is unusual due to the shoals of tope (a small shark species), which congregate in these waters.

This would finish off the day’s underwater activities before the Halton started to steam north through wonderful Nordic scenery. Several hours later, we moor up overnight. The work for the day has not finished, however, as microscopes come out and Mary and Joanne review the days samples.

Saturday brought another sunny day in Bergen. During the morning, all the luggage and equipment had to be transferred from the hotel to the boat. Amazingly we got everything, including the buckets and ourselves, into a large taxi for the short journey to the quay where the MV Halton was moored.

After loading, Mary, Joanne and Sally went through the Bergen Fish Market to catch a bus bound for the cable car up to Mount Ulriken. The market sells everything from live crustaceans, such as king crabs through to cavier and dried fish.

The bus dropped us off at the cable car where we found ourselves in the middle of a wedding party, who were heading up the mountain for the wedding ceremony! At the top, we got great views out across Bergen, looking down towards our first proposed sampling area for the next day, Vatlestruamen.

This week, I and 11 other marine scientists will be heading off to the Norwegian fjords to look at the effects of climate change on marine life. This includes four members associated with the Museum who investigate bryozoans (also known as sea mats or moss animals).

 

We are aiming to photograph and collect samples of current marine Bryozoa to assess changes in the species composition of the Norwegian fauna in comparison with historical surveys from circa 1900-1920 and 1963 in the Bergen and Trondheim areas. The collections will be done by SCUBA diving in the cold clear waters of the Norwegian fjords.

 

We are investigating to see if the species biodiversity has changed in response to increases in sea water temperature. The team will also be surveying artifical structures to look at patterns of distribution of non-native and invasive bryozoan species in north European waters.

The bryozoan research team consists of four members:

 

  • Mary Spencer Jones: Bryozoa and Entoprocta curator at the Museum
  • Dr Joanne Porter: Scientific Associate at the Museum/Heriot-Watt University Associate Professor
  • Sally Rouse: Heriot-Watt/Scottish Association of Marine Sciences PhD student and former Natural History Museum Encyclopedia of Life Rubenstein Fellow
  • Dr Piotr Kuklinski: Scientific Associate at the Museum/Institute of Oceanology Poland Associate Professor

The expedition kicks off on Saturday 28 June when the team join the research vessel MV Halton in Bergen and get all the equipment loaded on board. Joanne and I are making a visit to the bryozoan collection held at the Bergen Museum of Natural History prior to joining the cruise. Just time for a bit of final last minute packing before we head off on Thursday morning!

 

For more information on bryozoans, have a look at the Bryozoa of the British Isles Scratchpad website.

Artist Chrystel Lebas and Museum biologist and botanist Kath Castillo are exploring the E J Salisbury collection at the Natural History Museum and Kew Gardens Archives. They hope to use Salisbury’s images of Scottish landscapes to reconstruct environmental change over the last 50 years.

Chrystel and Kath began looking for clues that could reveal more about Salisbury’s research on ecology and botany through his methods of recording data, his travel journals and field notes. Delving into the 30 boxes of Salisbury’s documents has also revealed a small collection of hand written quotations, puns and limericks.

 

The Salisbury archive at Kew Gardens is currently in the condition in which it was received and will be fully conserved when resources allow.

Funding from the Calouste Gulbenkian Foundation permitted Kath Castillo to join Chrystel on her research in Scotland. Kath, who joined the project in September 2013, provides the necessary scientific knowledge (botanical and ecological) that enables geographical and botanical determinations in the field, based on Salisbury’s recorded images in the same locations.

Kath and Chrystel began the research and comparative study in Rothiemurchus Estate, a privately owned Highland estate within the Strathspey, northeast of the river Spey, in theCairngorms National Park.

The project engages with environmental change, particularly in the Scottish landscape, and creates new understandings of the artistic and scientific gaze onto the natural environment and its representation. The project is supported by a grant from the Calouste Gulbenkian Foundationand the University of the Arts London.

The Salisbury collection has, until recently, remained un-catalogued and undervalued. A collaborative approach to these materials is important as the plates represent an important piece of landscape and wildlife photographic history – UK natural history and photographic history knowledge and expertise will be essential to unlock the arts and science potential of this collection.

 

The images represent a unique record of landscapes that may have changed dramatically. They are an irreplaceable piece of the scientific information that may be used to investigate environmental change, either through natural processes or the hand of man.

Photographer and filmmaker Chrystel Lebas is working on a collaborative project to observe environmental change in the British landscape using the the Sir Edward James Salisbury Archive.

 

image-1.jpgChrystel photographed by Kath Castillo (Museum biologist and botanist) on their first research trip together in Culbin Forest in October 2013.

 

The Museum holds a beguiling collection of unexplored landscape images and field notes taken by British botanist and ecologist Sir Edward James Salisbury, who was Director of Kew Gardens from 1943 to 1956. The collection of over 1,400 works was orphaned – an anonymous assembly of Kodak boxes containing silver gelatine prints and photographic glass plates kept in two large cardboard boxes. The images record natural environments, capturing in particular botanical information in the United Kingdom and Ireland, to which specific annotations on the regions’ ecology were added.

 

Around two years ago photographer and filmmaker Chrystel Lebas was introduced to the collection by Bergit Arends (former Curator of Contempory Art at the Natural History Museum). Chrystel Lebas and Museum botanist Mark Spencer (Curator of the British and Irish Herbarium), began to trace this important collection, which was assembled in the first third of the 20th century.

 

image-2.jpgThe images include close-ups of plants and sometimes a foot appearing in the corner of the frame, presumably to indicate the scale of the specimen, or sometimes a subject, a woman standing amongst the forest trees.

 

Each of the boxes containing glass plates were scrutinised to look for clues that could indicate the author’s name or any information that could relocate the collection. And finally one day, and after a couple of months researching the collection, Chrystel found a glass plate negative with a handwritten name on it: E.J Salisbury, and of course this was the moment that made us realise that this particular collection was extremely valuable!

Chrystel began travelling to Scotland on her own, prior to the research being funded by the Calouste Gulbenkian Foundation. She started her research in the field and recorded the landscapes.

 

The focus of this project is on the Scottish landscape through Salisbury’s images taken between 1925 to 1933 in the following areas:

  • Arrochar in Argyll and Bute
  • the Trossachs National park
  • the Rothiemurchus Estate, a privately owned Highland Estate within the Strathspey, northeast of the river Spey, in the Cairngorms National Park
  • Culbin Forest, which sits on the Moray Firth between Nairn and Findhorn

 

The research contributes to a comparative landscape and botanical study spanning nearly 90 years.

Before I tell you about our time in the lab, I thought I would share with you another video taken by Paul Pearce Kelly in Cuc-Phuong. The video below is of a predatory slug species from the genus Atopos. These slugs either eat small microsnails whole or bore through larger snails' shells using their toothed, tongue-like radula.

 

 

 

After our exciting and productive time in Cuc Phuong National Park we headed back to Hanoi to process the material for frozen tissue collections. Our expedition has been jointly funded by the Natural History Museum and the Frozen Ark, and one of our aims is to collect frozen tissue material and viable cells.

 

The Frozen Ark was set up in 1996 and is run by a consortium of 22 universities, museums, zoos and aquaria from 8 different countries, with the aim to conserve frozen cells containing DNA from endangered animals before they go extinct. Since many limestone habitats are under threat from the construction industry (the limestone is used in the manufacture of cement and other building materials), we decided that terrestrial molluscs would be a great addition to the Frozen Ark collections.

 

chris and jackie.JPG

The specimens used for these processess have been brought back from Cuc-Phuong live, to be processed in the laboratory. For the frozen tissue samples, small slices of the foot of the snail (the part it moves on) are placed in sterile tubes and frozen at -80 degrees Celsius. These samples will hopefully yield high quality DNA. Five multiple sets are stored for our current research, long term Museum storage, the Frozen Ark in London, the Frozen Ark in Nottingham and for the Frozen Ark in Vietnam.

 

The viable cell preparations are also taken from tissue samples but they are mashed up in an antibiotic solution (to prevent damage by bacteria etc.), and then mixed with a buffer chemical so that as the tissues are frozen, again at -80 degres Celcius, the cells will not fracture and will remain whole. It is hoped that future technology will allow us to use these cells and the genetic content within to re-create and re-introduce extinct species.

The two experts in our group helping us with these processes are Jackie Mackenzie-Dodds and Dr. Chris Wade, who are both on the advisory board of the Frozen Ark. Jackie is the collections manager of the molecular and frozen tissue collections at the Museum, and Chris is a lecturer of genetics and a molecular biologist at Nottingham University. I'm glad they are both here as the frozen tissue preparations are complex and intricate and I have never done anything like this before.

 

We have spent the last few days collecting in Huu Lien Nature Reserve and tomorrow will be our last day collecting in the field so in my next blog I'll be telling you all about the strange and wonderful things we have found, and a little about our last few days in Hanoi.

 

Fruit for Thought

 

As well as the delicious savoury dishes we have been sampling a wealth of unusual (at least to me) fruit. My favourite has to be the Rambutan, a egg-sized red fruit covered in green hairs. I'm afraid I don't have any pictures because I ate them all before I thought to take a photo so you'll have to Google them. They taste a bit like a grape but are sweeter and juicier - delicious.

 

fruit.JPGPersimmon (the red fruit) and Guava's (the green ones) with a little lotus tea - what a lovely afternoon treat.

 

We've also been eating ...

 

Pomelo - a sharp citrus fruit with a grapefruit-like taste

Guava - like a tropical quince

Persimmon - a bit like across bewteen a plum and a tomato, much nicer than it sounds

Longans - like large lychees but sweeter

Forest Bananas - shorter but wider than our usual bananas, tastes earthier and banana-ery if that makes any sense

Jicama - a tuber that tastes like apple and is often served with savoury courses

 

Bite Me

 

0 Leech bites ... all though I have a funny feeling this may change tomorrow as it is due to be a stormy evening

We've been amazed by the amount and diversity of snail species in Cuc Phuong. We knew it was rich but we have found so many new and exciting species that we are struggling to process all the material (a good problem to have). The weather has improved slightly (good for us) but the ground and leaf litter is still really damp for collecting (good for the snails, everyone wins!).

Paul Pearce Kelly, the Senior Curator of Invertebrates and Lower Vertebrates at London Zoo, is joining us on field work for the first time. His aim (apart from helping us to collect snails) is to build up links with different groups in Vietnam to help conserve and study threatened species.

 

After finding some thought-to-be-extinct snails on our Vietnam trip in 2012, we hope that Paul, in conjunction with the Vietnam National Museum of Nature, will be able to set up a breeding programme to protect them against threats in future. As well as helping us collect, Paul took some great videos of animals alive in the field and he has kindly let me share them with you in my blog. In this one you can see the as yet unidentified  'looping snail':

Another member of our group I'd like to introduce to you to is Jonathan Fenn, a biology placement student from Manchester University. Jonathan has been working with Fred and I for the past year on producing an illustrated guide of the slugs and snails of Northern Vietnam, as well as a species list with distribution data for terrestrial molluscs across the whole of Vietnam. The aim of the trip is to teach Jonathan more about fieldwork, collecting and preserving snails, and to gain experience in preserving viable cells (which I will discuss in my next blog).

As well as snails, the forests and local areas are home to an amazing array of different animals. One of my favourites (not including the enormous spider that lives in my toilet, didn't think you would want a picture of that) was the praying mantis species I found outside my bedroom (see below). Sadly I missed the Vine Snake (Ahaetulla sp.) that my co-workers found when searching the trees for snails.

So gutted I missed this Vine Snake (Ahaetulla sp.), what a beauty!

 

Since we'd all been working so hard we decided we deserved a visit to the Endangered Primate Rescue Center (EPRC) in Cuc Phuong National Park. The centre was established in 1993 and is dedicated to the rehabilitation, breeding and research of endangered primates as well as the protection of their habitats. The EPRC is home to over 150 primates from 15 Vietnamese species, including lorises, langurs and gibbons. My favourites were the wonderfully playful Gray Shanked Douc Langurs.

Our guide for the afternoon was Liam Shepheard, head animal keeper, who showed us the remarkable centre and told us about the amazing work they do in rescuing and when possible re-introducing animals back in to the wild. One species of Laotian Langur (Trachypithecus laotum) named 'Airport' is the only individual of its kind in captivity and is thought to be critically endangered in the wild. At times the stories were a sad and sobering experience but the success they are having is remarkable and it was real treat to be able to see these beautiful creatures up close.

 

Carnivore and Pangolin Rescue Center

 

After meeting the directors of Cuc Phong National Park over dinner the previous evening, we were invited to visit the Carnivore and Pangolin Rescue Center, a massive privilege as this is not normally open to the public. Many mammal species are being hunted for meat, the pet trade and in the case of the Pangolin, for Chinese medicine (the scales are used in medicines and the meat is regarded as a, ahem, male performance enhancer). The centre was set up to rescue illegally found animals and to develop techniques and procedures to allow the rehabilitation, breeding and reintroduction of such species back in to the wild.

 

We visited the centre at night, which is the best time to see the majority of the animals. Pangolins are my favourite mammal and I have never seen one before so this was a real highlight for me. The animal we met was called 'Lucky', a Sunda Pangolin who had been saved from captivity but who was sadly too tame to be re-introduced.

The Binturong (Arctictis binturong) - the cutest thing I have ever seen. Numbers have dropped due to hunting.

I also got to see another favourite of mine, the Binturong, a south-east Asian mammal related to civets whose numbers have been declining in the region due to threats from poachers.

 

A Few Thoughts from my Stomach

 

We have had some delicious and some challenging food in the last few days. Fried mixed mushrooms and chilli roasted chicken have been superb, whereas mixed offal and pak choi soup was something I am keen to avoid in the future (and I like offal). But today I thought I would tell you a bit about some of the mealtime extras I have enjoyed.

 

Nước chấm is the name of a group of dipping sauces that are commonly served with meals that have a fish sauce base, often mixed with garlic, bird's eye chillis, garlic and sugar, with the precise mixture depending on the region. This sauce is, I think, delicious with morning glory and .. well, actually pretty much anything although a few of our group find it a bit overpowering (I would take some home but it is prohibited by most airlines as if it leaks it tends to smell forever!)

 

At the behest of our Vietnamese colleagues of course, we like to round the day off with a glass or two of Mountain Apple Brandy. The precise ingredients of this sour but delicious beverage are a closely guarded secret, and it is homemade by the wife of our driver, Mr. Kiem. I have however managed to find out that it contains a sour apple-like fruit, rice wine, mixed berries and a selection of herbs and bark. Whatever it is I'm sold!

We arrived in Cuc Phuong National Park on Friday afternoon. Set up in 1962, the park is the oldest in Vietnam and covers an area of over 22,200 ha. It is home to more than 2,000 species of trees, 110 species of reptiles and amphibians, 308 species of bird and 125 species of mammal, including the Clouded Leopard, Delacour's Langur, Owston's Civet and the Asian Black Bear.

 

Since the national park is so rich in snail diversity we could barely wait to start collecting and bagged our first few specimens as we excitedly stepped out of our van. After a hearty meal (more later) and a good night's sleep under our mosquito nets we were ready to head out into the field. Our first collecting site was a limestone outcrop, which also contains an archaeological cave where human tools and remains dating to over 7,500 years ago have been recovered.

 

Chasing Snails

 

Collecting snails is harder than it sounds, as we have to make sure we get specimens that live in soil and leaf litter, on the rocks and stones, in the trees and on vegetation. In the hot and humid conditions of the tropics this is difficult and sweaty work, but at least when we do find them they aren't too hard to catch.

instructer Frd.jpgFred Naggs (R) gives Hao Luongvan (L), Mr Kiem, our driver (C), and myself a quick Iecture.

 

On our first day we found an amazing variety of specimens, from microsnails less than 1mm tall that hide in the crevices of the limestone rock face, to larger and often strikingly coloured species. One of my favouites was the white form of Camaena gabriellae (pictured below left) which we found crawling on the bark of trees and managed to catch by knocking them with a stick in to a traditional conical Vietnamese hat, which did the job perfectly.

 

I am also particularly fond of the elongate group of snails called the Clausiliidae (pictured below right), which are found on limestone in large numbers, their bodies barely peaking beyond the shells as they graze on lichens and algae.

 

2  snails small.JPG

Species found on day one include Camaena gabriellae (L) and Tropidauchenia sp. from the Clausillidae (R).

 

Today I would like to introduce you to another Vietnamese member of our team, Mr Hao Luongvan (pictured in first image). Hao works for the Forestry Commision and is based in Hoang Lien National Park, Sapa in northen Vietnam. He has been studying molluscs for the last ten years.

 

We first met Hao on our visit to Cuc Phuong in 2007 and have worked closely with him ever since. Not only does he a have an encyclopaedic knowledge of the variety of habitats, plants and animals across Vietnam, but he has been instrumental in helping us gain access to different national parks and make vital links with important government and conservation departments.

 

Turtle Power

 

After a hard day's work we managed to fit in a visit to the Cuc Phuong Turtle Sanctuary. The centre was set up in 1998 as a safe area to house and breed the 19 native species of Vietnames turtles (of which 3 are found in Cuc Phuong), as well as to increase public awareness of the threats poaching poses to these amazing creatures.

 

TURTLES.JPG

Terrapin in Cuc Phuong Sanctuary. Poaching is the main source of their decline.

 

The centre was really inspiring, as to date over 900 turtles have been born there from animals confiscated from illegal traders. Plus we got to sit on a life-size model of the Yangtze giant softshell turtle (Rafetus swingoei), which can reach over a metre in length.

 

Specimen Sorting, Identification and Preservation

 

After our brief foray in to the world of chelonians it was time to get back to work. The first job is to sort all the snails into species based on shell and body shape, colour and sculpture (sculpture means the 3D surface - is it ridged, smooth or bumpy etc.). Once we have done this we choose one specimen to take a tissue sample from, and preserve this in 100% ethanol for molecular analysis.

 

snail-sorting.jpgSorting snails in the sunshine, it's a hard life ... honest.

 

We then split the remainder of the individuals into those to be preserved in 80% ethanol for anatomical analysis and those to be taken back to Hanoi alive for viable cell preservation (more on this in a future blog post). This is my favourite part of the collecting day as we get to compare what we have found and there is always something unusual or unexpected - this time we had both aplenty! On our first haul we could not believe the diversity and volume of species we managed to collect - this really is an amazing habitat for molluscs and even more exciting than usual as we think in our first day we not only have a new species or two but possibly even a new genus .... so watch this space.

 

Food For Thought

 

After a long but fruitful day it was time to retire for dinner and no blog post of mine would be complete without some mention of food. Tonight was the first time on this trip that I got to have some of my favourite Vietnamese food; a green vegetable called Morning Glory (rau muống in Vietnamese or Ipomoea aquatica in science speak). The spinach-like stems and leaves are fried in garlic and chilli and are bitter but wonderfully moreish. I ate more than I should have with fried chicken, sesame roasted pork and sumptuous sticky rice washed down with locally made Vietnamese brandy (don't ask!).

 

DSC_1016_small.JPGMorning Glory (Ipomoea aquatica) the green stuff on the left ... much nicer than it looks!

 

As I write this (in the courtyard of our accomodation with toads barking and cicadas chirping) I have just finished sorting out Sunday's specimen haul, also an impressive bounty, and I will be reporting back shortly on some new and exciting discoveries along with some of our further adventures in Cuc Phuong.
