Last night, we arrived back at the hut just before dark and ate a dinner of soup (chicken) and rice (sin bean). Over dinner we learnt that, in our absence, Holger and Jo had a productive time (more on that below) and it was nice to be all back together again.

 

Today I stayed at the hut (checking everything was working for our next live-video-link back to the Museum which will be happening just as this is published) so I had the chance to chat to one of the porters assisting our trip.

 

Day 10 PIC 1.JPG

Daniel Lezcano Arguello and Carlos Godinez Cardenas

 

Daniel Lezcano Arguello started off by apologising for laughing at my new nickname - which has morphed from Yeti via Crouchy (as in Peter, the lanky, robot-dancing footballer) to Pie-Grande. I pointed out that Yeti and Pie-Grande are absolutely fine but Crouchy has most definitely got to go - I am an Arsenal FC fan!

 

He told me about his life when he is not working as a guide or porter. He is a farmer and has 5 hectares near the entrance to Amistad National Park where he grows coffee and bananas and keeps pigs and cows. The coffee he sells to a large Costa Rican company although he keeps a bit back for personal use as he prefers to know what is in his morning cuppa. The bananas are used to feed the cows and pigs.

 

The cows are for milk and he makes cheese, and the pigs are for meat. He also grows some vegetables and we swapped allotment stories although he seemed pretty unconvinced it was possible to grow anything in British temperatures.

 

He said he is typical of the porters in that they all farm when not guiding people through the park. This trip (like most field work, I imagine) would be impossible without the help of the porters.

 

They prepare trails and camps and ferry specimens and food to and from the field, and they carry extraordinary amounts and move incredibly quickly through the forest. This is the head porter and our guide Carlos.

 

Day 10 PIC 2.jpg

Head porter Carlos making his work look easy while I struggle to keep up (hence the blurry photo!)

 

He is carrying a backpack, a few litres of water, camping equipment for 4 and - if that wasn’t enough already - a shovel.

 

Day 10 PIC 3.jpg

Leandro taking a breather

 

I am in awe of their strength and athletic ability at this altitude and their commitment to our trip. They have an invaluable knowledge of the forest and are key in helping us find interesting sites and species. Also, they are vital for the conservation of the park so we are doubly thankful for what they do.

 

Species of the day today goes to Holger - the result of 2 hours hard work, blood, sweat and tears!

 

Day 10 PIC 4.JPG

 

Holger found three different stream lichens with a high likelihood that they may be new for Costa Rica and maybe even new to science.

 

Day 10 PIC 5.JPG

 

 

This lichen is a representative of the family Lichinacae and fresh water species of this family are commonly found in Nordic countries.

 

Day 10 PIC 6.JPG

 

Day 10 PIC 7.JPG

 

Holger didn’t expect to find something like this here and all of the lichens Holger has found reflect a climate far, far colder than would have been expected - something we can vouch for during the long cold nights!

 

This is why lichens are so important in that that they tell us so much about our environment. Sadly, no video today – I hope to get back to business tomorrow.

 

(Just a quick reminder that Alex is also writing his own blog about our trip and you can read it here and that our next live-video-links with the Museum are at 12.30 and 14.30 on Saturday 18 February)

At the end of day 8, in order to be nearer our site for the next day's work and to finish pressing, we did decide to camp out on the peak (see yesterday's post).

 

Day 9 PIC 1.JPG

(Click images to see them full size)

 

We set up our tent at the top and set about making a dinner of soup and pasta.

 

Day 9 PIC 2.JPG

 

This was the most incredible place to eat and sleep - on top of a rock, the forest floor hundreds of metres below on either side of us. The picture below shows the peak.

 

Day 9 PIC 3.JPG

 

Over dinner we watched the weather, which was better than any TV programme. It was amazing to see clouds form below us and then race up the side of the mountains and roll by while turning the color of the setting sun to orange and then grey.

 

Day 9 PIC 4.JPG

Day 9 PIC 5.JPG

 

I tried to capture it on film.

 

 

The next day, having been buffeted by the wind all night, we rose early and made some coffee and scrambled eggs. Someone (either Daniel or Alex ) took this horrific photo of me in the night!

 

Day 9 PIC 6.JPG

What is it? A Yeti?

 

We had a tin of tuna going spare, but couldn’t face it that early!

 

Today we are collecting on the neighbouring peak and after lunch we will walk back to our hut for the remainder of our stay. The descent and climb between the two peaks was dramatic. I did most of it on my backside! Sliding down the mountain holding on to anything that didn’t come away in my hand.

 

Day 9 PIC 7.JPG

 

Every time we venture further into the forest, all the places we’ve already been to seem to feel less wild and more hospitable.

 

Coming down the peak from our camp last night, the forest below began to feel familiar and safe (I promptly fell between two trees, bringing me back down to earth, metaphorically and literally - with a bump) and I completely understand why visiting places like this can become addictive.

 

Apologies for waxing (poorly) philosophical - it is Valentine's Day as I write this and I’m feeling whimsical!

 

Back to why we're here... Species of the day goes to Daniel and is a new species (probably)!

 

Day 9 PIC 8.JPG

 

Day 9 PIC 9.JPG

 

It is a member of the genus Blackea and normally this genus is epiphytic (i.e. it would grow on other plants) but this one is a small tree, three metres high and has pale translucent green flowers unlike any other species in the genus that we're aware of.

 

Daniel is pretty sure it is a new species but we can’t be 100% until it has been checked.

 

Also, I should have said a few days ago, Holger and Jo stayed back at the hut as there are more sites of interest to them in that area than up the peaks, so we’ll catch up with them this evening.

Last night we had lentils instead of beans and I almost cried with joy. They were amazing and had small pieces of pork nestling in the juice. Yum...

A bit of yeti red-eye going on there!

I have been given a nickname by Daniel, our Costa Rican collaborator. He is known as Santa - to be fair, that is his actual name (he’s Daniel Santa Maria) - and I am now known as ‘Yeti’ - due to my large boots.

 

Day 8 PIC 3.JPG

 

Daniel amused himself no end with jokes about collecting Yeti footprints for the Museum. My Spanish is too poor to be clever in the response so I’m accepting my fate: I am the mythical giant of the Himalayas with huge boots.

 

In the night we were woken by an earthquake - it felt quite gentle (we were sleeping on the floor) but this report shows it was actually quite strong!

 

I was sleeping so deeply that my main emotion was one of annoyance at being awoken rather than fear. Still, an experience none the less!

 

We got up early, had a second bash at the lentils and set off for our collecting site for the day – Cerro Tararia. The walk was incredible, a lot of scrambling up and down.

 

Day-8-PIC-4.jpg

 

This place is amazing, a rocky outcrop with views that stretch for miles.

 

 

We are 2,730 metres above sea level and our coordinates today are N 09 08 52.0 W 082 58 02.7 (click to see on a map).

 

The sound is a little obscured at times in the film above due to the wind (sorry about that), but you can make out Alex saying that Panama isn't far from where we are, and the border is visible on the map linked above.

 

The views from the top are stunning.

 

Day-8-PIC-5.jpg

Day-8-PIC-6.jpg

 

Species of the day is a member of the genus Schultesia. Daniel is not sure whether it is a new species or not but he has never before seen a Schultesia with purple flowers as they are normally white.

 

Day-8-PIC-7.jpg

 

Alex and Neil were discussing what it could be pollinated by and decided it was probably bats. The flower’s pistil and stamen are quite a long way apart from each other and it has a long tubular corolla, so a bat’s long tongue would be the perfect tool!

 

Day-8-PIC-8.jpg

 

We are just debating whether to sleep on the rock or walk back to the camp. Sleeping out here would be incredible. I’ll let you know if we did or not tomorrow!

Breakfast was sausages – yes! Salty and oily they took my good friends rice and beans to a whole new level.

Today we set off from our hut, to the camp we are going to stay at for the next two days – N 09 08 09.4, W 082 57 38.4 are the co-ordinates: view on a map.

 

Our route took us along the river.

 

Day-7-PIC-2.jpg

 

Day-7-PIC-3.jpg

 

We walked for a couple of hours before climbing up to a point called Jardin. This area is completely different from anything I have seen so far on the trip – it’s a peat bog and is dominated by tree ferns that have islands of mosses, lichens and sedges growing around them. It was a rare break in the forest canopy and there were some spectacular views.

 

Day-7-PIC-4.jpg

 

It was a really challenging crossing - impossible to know whether your next step was going to hold fast or leave you knee deep in the bog.

 

Day-7-PIC-5.jpg

 

We then dipped backed down through the forest – not so much a trail as a thrash through the bush!

 

Day-7-PIC-6.jpg

 

Once at the camp, I set up the equipment for sending you my post - solar charger and satellite phone - and made a little tour of the camp.

 

Day-7-PIC-7.jpg

 

 

On the way here I saw the first sign of a wild cat – this is Ocelot poo, apparently!

 

Day-7-PIC-8.jpg

 

Species of the day goes to Neil (though Alex is making a spurious claim!). It is in the genus Pilea (in the nettle family) and Alex thinks it may be a new species! He is a world expert in the nettle family and, in particular, this genus - although this looks similar to another species of Pilea it has a key difference in that the leaves are of equal size to each other as opposed to being different sizes.

 

If it is a new species Alex will be able to publish a description of it and give it a name, but he can only be sure that this is a new species once he has checked it against similar species housed in herbaria.

 

Day-7-PIC-9.jpg

 

This really highlights the importance of the trip and of collecting in general. In order to know exactly what is in the park and make as complete a check-list of the species as possible, we have to know what lives here. These specimens will be available for future generations, who may have other uses for the data they provide.

 

Of course, it is important not to collect too much, we rarely collect a whole plant and always make sure we don’t collect without the correct permits which are provided by the Costa Rican government.

Food update! We have been brought a butchered pig to add to the holy duo of rice and beans – this is a gruesome picture of the skin but the meat was delicious! I have also spied some sausages amongst the supplies and wait eagerly for their appearance at the dinner table!

Day 6 Pic 1.jpg

(Click the images to see them full size)

 

The main aim of our trip is to document the biodiversity of the area and collect different species of plants. We take five copies of each species – one goes to INBIO, one to the Missouri Botanical Garden, one each to the National Herbarium of Panama and the National Museum of Costa Rica and one to the Natural History Museum.

 

Collecting is a meditative process and it is wonderful to be in the field as a team, finding out what the environment holds. Amongst the flowering plant team (Daniel, Alex and Neil) the duties of collecting are split: today, Daniel searched out the different species in the area and collected them, Neil and Alex set up a small processing area - one photographing and taking DNA samples of each species and the other pressing the five copies of each species between sheets of newspaper.

 

I had a go at pressing but my main duty was the honourable task of pressing down on the pile of specimens, a job that you may think could be done by a rock or gravity but Neil described my contribution as very useful, so here I am hard at work:

 

Day 6 Pic 2.jpg

 

These specimens are bagged up and brought back to the hut at the end of the day where they are placed in sealed bags full of 70% alcohol, which stops them rotting. These specimens will be carried down the mountain and dried on heaters before being sent to the various institutes to be mounted and added to their collections (a collection of pressed plants is called a herbarium).

 

Day 6 Pic 3.JPG

Neil explained the process to me in the field:

 

 

The DNA is stored in silica gel which keeps the samples dry by absorbing the moisture in the atmosphere. I have lots of the stuff (which I keep in tied-up tights) to try and keep all my equipment - kindly lent to me by the museum - free from moisture.

 

I made what could be the 'driest' video of all time about how you dehydrate the silica once it has done it’s job and is saturated with liquid - dry-fried next to the omnipresent beans, so worth watching for that scene if nothing else. My silica is dark blue when saturated with moisture and orange when dehydrated:

 

 

Species of the day – Vaccinium bocatorense (collected by the flowering plants team) is very closely related to the blueberry and grows between 1.5 to 2 metres tall. It’s endemic to the national park so is not found anywhere else in the world and it’s a beauty!

Day 6 Pic 4.jpg

Tomorrow we set off to spend a couple of nights camping at a location a few hours walk form our hut - I will try and blog from there but if things go quiet due to lack of internet access, I’ll be back on Wednesday.

Continuing my food theme... Today we had pancakes for breakfast (not rice and beans) and they were about an inch thick and flavoured with vanilla. I had mine with maple syrup and am feeling very happy with myself!

 

Day 5 Pic 1.JPG

(Click the images to see them full size)

 

After a few days of staying around the hut, today I got the chance to go out with the botanists into the field and experience collecting. We went to a place called Laguna.

 

Day 5 Pic 2.jpg

 

There are several specific sights of interest that the botanists target each day – we had a live-link back to the Museum to do in the morning so chose a site nearby (see the map below - we are staying at Albergue Valle del Silencio and Laguna is due East-South-East from there).

 

Day 5 Pic 3.JPG

 

I am going to blog about the specifics of collecting tomorrow but today wanted to focus on the trails cut for us in order to reach the collection sites. Some trails are clear, well worn by the porters ferrying supplies and specimens to and from the camp, others are cut specifically for us and are much less easy to follow.

 

The forest is so dense it is easy to lose ones bearings. Today I tried to keep my orientation between a river and mountain but soon the dense foliage span me around and I felt completely at the mercy of the forest. It is a wonderful feeling to be lost - as long as you’re with someone who isn’t!

 

Because the forest is so dense sound doesn’t travel too far so Alex and Daniel Santa Maria (a botanist from INBIO - The National Institute for Biodiversity in Costa Rica) use calls to locate each other.

 

 

 

Daniel has an amazing knowledge of the local plants and is invaluable to the trip. Here he is having a rest after lunch in the field.

 

Day 5 Pic 4.jpg

 

Species of the day today is Conopholis alipna and was collected by Daniel and the flowering plant team (Alex and Neil). It is a parasite that targets the roots of oak trees which are the predominately tree in the surrounding forests.

 

It gets all of it’s nutrients from it’s host and is found at altitudes of between 2,000 and 2,700 metres. It's my species of the day because I think it looks really cool:

Until tomorrow!

So today I have had the chance to spend a bit of time at the hut - I made a video to hopefully give you an idea of what it’s like! (Also I meant the water is clean enough to drink, not eat! Sorry it must be the altitude, which is 2,500 metres - you can see on Google Maps the exact location of where we are.)

 

 

For breakfast the ubiquitous rice and beans made a welcome appearance - last night was really cold (definitely in the lower single figures!) so some hot food and drink was more than welcome. By mid-day it had warmed up considerably and the sun was hot.

 

(I should make it clear that I am in no way complaining about rice and beans - I love them! Last night they were joined by a hot, steaming pot of chicken soup and dinner was great.)

 

The scientists went out collecting today (the first chance to have a proper explore since they arrived) and they found some great stuff! However, Neil has already suffered some really nasty sandfly bites.

 

Day-4-PIC-1.jpg

N.B. I've enhanced the colour of this photo a little so that you can see the bites more clearly.

 

Species of the day goes to Holger (although he found it yesterday). It’s on this stone, which he found in a nearby stream 30 cm below the water level. He had to chisel the lump off with both hands underwater and he described it as the single most difficult specimen he has ever collected.

 

Day-4-PIC-2.jpg

 

It’s a representative of the genus Hydropunctaria and this is the first time it has ever been recorded in tropical America - it is found widespread in more temperate areas and in cold mountain streams in SE Asia and South Africa.

 

It is one of the best indicators of a stable stream bed and only lives in constantly cold water. Therefore it is an important species to know about when considering climate change. Now that Holger has found this specimen future generations will know that it was living here in 2012.

 

Day-4-PIC-3.jpg

 

Now it may look like a dark patch on a dirty rock (Alex’s words not mine!) but Holger gave the following quote:

 

‘Perfect circular shape, a beautiful olive green hue and a texture of half solid jelly which is just amazing.’

 

Wow, I’m going to have a cold shower ... which is good news as we don’t have any hot water! I’m going to blog more about lichens next week.

 

With one new discovery under our belts, I hope the photos from my previous posts give you an indication of just how rich the plant life is here. Alex tells me that there are more than twice as many species of plant in this park alone than in the whole of the UK.

 

Day-4-PIC-4.jpg

 

He has written a really nice piece on his own blog about the forest here - do have a read.

 

Finally, if you want to experience a live video-link direct from our hut to London tomorrow (and also on the 16 and 18 Feb) please come to the Nature Live event in the Museum's Attenborough Studio to say hello! They'll be held at 12:30 and 14:30 and (barring any technical issues) we're going to be joining the event to answer questions from the Studio and to show you a few specimens.

 

Jo (Nature Live host) and Erica McAlister from the Department of Entomology will be in the Studio to talk about field work, why it’s so important, what it’s like and how you do it, etc., so please do pop down to South Kensington.

 

Also, I wanted to let you know that, unfortunately, due to my limited internet connection I can't see your comments until they are e-mailed to me, so my apologies if you have had any questions which remain unanswered – I’ll do my best to respond in the next few days.

Today we rose early! By 7.00 we had left base camp and were beginning the 6-8 hour trek [I sit here smug, we did it in just over 6] to the hut that is to be our home for the next week and a bit. Breakfast was rice and beans (a theme is emerging!).

 

Day-3-PIC-1.jpg

(Click the images to see them full size)

 

The first half of the trek was uphill (i.e. absolutely knackering) but the views from the occasional break in the canopy were breathtaking and kept us pushing on.

 

Day-3-PIC-4.jpg

 

We are working alongside Costa Rican botanists, one of whom is Daniel. He has an incredible knowledge of the local environment and found this plant, Satyria warszewiczii on our trek.

 

Day-3-PIC-5.jpg

 

The flower’s corolla (a corolla is when all of the flower’s petals have fused into a tube) is edible and tastes a little bit like bitter lemon or blueberries (or vinegar depending on who you ask!):

 

 

After 4 hours we reached the continental divide, the point at which Costa Rica splits between Atlantic and Pacific forest. Water that falls either side of this divide ends up in either the Pacific or Atlantic ocean. Alex had a unique way of explaining this:

 

 

The forest changed dramatically once we were on the Atlantic side - on the Pacific side our path had been dry and dusty but once we crossed over, the forest was damper, darker, cooler and wetter. This is because the prevailing wind blows from the West.

 

The wind picks up moisture from the Atlantic Ocean and Caribbean Sea and carries it to the western Atlantic slopes of the forest before dumping it there. Therefore, because less water reaches the Pacific side, it’s much drier.

 

Day-3-PIC-6.jpg

Day-3-PIC-7.jpg

 

The rain increased as we got closer to our hut. We arrived damp and tired but very excited about the days ahead.

 

The camp is made from naturally fallen trees from the forest and the roof is corrugated iron - the sound of the rain drumming above me as I sit inside with a coffee is wonderful!

 

Day-3-PIC-8.jpg

Day-3-PIC-9.jpg

I’ll post some more pictures of the camp tomorrow - the battery in my camera has run out of juice and our generator is not yet up and running.

However, we found some really nice things on the way, this is a beetle grub:

 

Day-3-PIC-10.jpg

Day-3-PIC-11.jpg

 

And this beautiful moth:

 

Day-3-PIC-12.jpg

 

I'll have to see if the Museum's enotmologists know what species they are...

 

Tomorrow we start collecting and the hard work begins but Holger has already had success after popping down to a nearby stream and finding two species of lichen never recorded in Costa Rica before.

 

Tonight, more beans and rice and early to bed.

 

------

 

Remember we'll be live-linking from Costa Rica to the Museum's Attenborough Studio at 12:30 and 14:30 on Saturday 11, Sunday 16 and Saturday 18 February so, if you are in London, come along to see how we are getting on!


The Attenborough Studio is located in the Darwin Centre in the Museum's Orange Zone.

After our first night in Costa Rica, it was a breakfast of pastries (spicy cheese – delicious!) before we packed up and headed off from INBIO.

Day-2-PIC-1.jpg

(Click the images to see them full size)

 

The drive was 6 hours and was spectacular from start to finish. We drove higher and higher along the ridge that cuts down Costa Rica until we reached Everest - not the mountain (wrong continent!) but the name of a rest stop - for a mid-morning snack. Fried cheese and tortilla (equally delicious).

 

We then enjoyed and took full advantage of the greatest view from a urinal probably anywhere in the world.

 

Day-2-PIC-2.jpg

 

I took some footage of the drive - please excuse the jumpiness as it was very bouncy and I had to edit the film in the back of the jeep! Better will follow, I promise.

 

 

Soon the road turned to dirt track and we entered the Amistad National park.

 

Day-2-PIC-3.jpg

 

We stopped at Asoprola for a beautiful lunch of beans, fried chicken, plantain, rice and salad. Asoprola is a wonderful hostel run by a co-op and was decked out in a wonderful mosaic.

 

Day-2-PIC-4.jpg

Day-2-PIC-5.jpg

 

I also saw a really cool lizard that put on a nice little show!

 

 

After lunch and a short drive we reached the end of our journey by jeep and the beginning of our first trek.

 

Day-2-PIC-6.jpgDay-2-PIC-7.jpg

 

Two hours later and I am writing from a hut as dusk falls on a very cloudy evening.

 

The trek was amazing the air and forest is thick and everything buzzes with life. Tomorrow we will trek for another 8 hours to reach our second (and final camp) so I’ll be able to post more then.

 

It’s dark now and we only have a few petrol lamps and some fireflies for light. Amazing!

We have arrived in Costa Rica!

 

From a snowy North London...

 

Day1-PIC-1.jpg

 

Via some beautiful skies over America…

 

Day1-PIC-2.jpg

 

... to spending the night at INBIO (Instituto Nacional de Biodiversidad) - the Costa Rican National Institute for Biodiversity.

 

And already my botanical education has got underway - this is Holger outside Newark airport...

 

Day1-PIC-3.jpg

 

This is what he is looking at...

 

Day1-PIC-4.jpg

 

... which is a moss (the green bits, that is). Holger says you can tell this is a new pavement and not just a very clean one because there are mosses but no lichens. Lichens are slow to grow, apparently! Here’s hoping for some more spectacular specimens in the tropics.

 

I'm off to bed as it's very late here in Costa Rica but tomorrow we will drive for most of the day to reach Altamira. If we get there early enough, we will climb to our first camp, otherwise we will have to wait until the next morning for our first hike.

 

See you again tomorrow.

The trip to Costa Rica is led by Dr. Alex Monro who has his own blog where you can learn about his interests and research. But here is some information about the other scientists, and their expectations for the trip:

 

Neil Brummit.jpg

Dr. Neil Brummit is Researcher in Botanical Diversity

 

Area of Botany you’re most interested in

My main botanical interest has always been in biogeography - working out why some distant areas of the world have the same plants, while other areas close to each other have different plants. Also, I study why some areas of the world have so many more plant species than other areas do, and try to identify these areas and the threatened species they contain accurately enough to help with plans for their conservation.

 

Best thing about being a Botanist

When you can see that your work has been useful to someone else, especially someone outside of botany, it gives you a sense that your efforts have been worthwhile. For example, a big project that I have been involved in for several years has estimated how many plant species worldwide are threatened with extinction, and when we announced results from this project in 2010, it was covered in hundreds of media outlets around the world and we also travelled to the Conference of the Parties to the Convention on Biological Diversity meeting in Nagoya, Japan, to make a presentation there. At the end of the meeting there was a renewed determination by the world's governments to take positive conservation actions in the next few years, and I did feel that, in our own small way, we were a part of the scientific response to the loss of global biodiversity that had helped to galvanise the political will to make that happen.

 

Previous field work

A little bit of everywhere; I´ve done fieldwork on each continent, but I´m always keen to visit new places. For me there is always something special about being in Africa, perhaps because that was my first experience in the tropics. I think once you´ve been collecting in the tropics, everywhere else seems a bit boring by comparison. I was still at school when I first went on a proper field trip, to Malawi with my father (who is also a botanist); I loved it, and remember thinking that he was paid to do this!

 

Favourite thing about working in the field

Seeing new plants, and thinking to myself "Wow, what on earth is that?". If I can attempt an identification that is somewhere close to what it is, even better.

 

Least favourite thing about working in the field

Leeches and mosquitos; Listening to rats running around you in the dark when you are trying to sleep at night; Never being clean; Missing being at home with my wife;

 

What are your hopes for this trip?

Hopefully I will have the opportunity for more fieldwork in Costa Rica, so for me this is a chance to experience the country but, perhaps more importantly, get to know the people working there and start to build relationships with them. I´m grateful to be going with someone like Alex who has already had a lot of experience there, and I´m looking forward to working in the field with him.

 

What one piece of advice would you give someone going on field work for the first time?

It´s hard work! Don´t expect too much, as all the best laid plans can go out of the window very quickly; be prepared to adapt.

 

 

Jo Wilbraham.jpgJo Wilbraham is Senior Curator, Algae

 

Area of Botany you’re most interested in

Non-flowering / cryptogamic plants, particularly bryophytes

 

Best thing about being a Botanist / Curator

Being able to spend time obsessing about your favourite plant group as part of your ‘proper job’ and being able to work with the wonderful collections here at the Natural History Museum.

 

Previous field work

My more recent fieldwork has been around the beautiful British coastline looking at seaweeds.  I’ve also been on fieldwork trips to Reunion Island, Ecuador, Belize and Sulawesi, so Central America is new territory for me.

 

Favourite thing about working in the field

Exciting times looking for plants (and no access to work email).

 

Least favourite thing about working in the field

Sharing a camping hut with vampire bats wasn’t very nice, but mostly I’d say missing the folks back home.

 

What are your hopes for this trip?

My underlying goal is to contribute more data to the question ‘what grows where’, hopefully increasing knowledge of rare / poorly understood species and the habitats they live in.  I will be collecting specimens for long term preservation in the NHM herbarium where they will be available to researchers around the world who are studying these groups – both now and in the future!

 

What one piece of advice would you give someone going on field work for the first time?

Remember to pack your sense of humour… and a hand lens!

 

Holger_LymeRegis.jpgDr. Holger Thues is Curator – Lichens

 

Area of Botany you’re most interested in

All the oddities traditionally studied by botanists but which are in fact not related to plants (eg. fungi, slime-molds etc.). Within “Green Botany” my current main interest is in lichenised algae (photosynthetic symbiotic partners in lichens) and particularly their compatibility with various lichens in different habitats.

 

Best thing about being a Botanist

I regard myself as a biologist. In my current role as curator at the NHM my focus is on lichenised fungi and their associated algae – this makes me a part mycologist / part botanist. Before I came to the NHM I was working partly as a researcher and partly as an environmental consultant. This included work with lichens, mosses and seed plants but also with various animal groups: from aquatic invertebrates, leafhoppers to hamsters and salmon. I like the constant change of the profession “biologist”  - although the fundamental questions have remained surprisingly similar over thousands of years: from the stone age to the time of worldwide industrialisation: biologists always look for answers to the questions: what to eat (and what not?)  what is harmful?  what is beneficial? And what does it all mean in a wider context? I can hardly imagine a more interesting profession!

 

Previous field work

Mostly all over Europe (particularly “rocky” habitats from coastal cliffs to alpine peaks – you can easily locate me in the field by the sound of my chisel). In the tropics so far two field trips to the Venezuelan part of the Andes (focussed on freshwater habitats in open areas with Paramo-vegetation).

 

Favourite thing about working in the field

Asking questions directly to the living organism in its environment, physical activity, absence of paperwork

 

Least favourite thing about working in the field

Travelling to the study sites, paperwork in advance of a field trip

 

What are your hopes for this trip?

As a curator my main hope is to collect a rich selection of fresh lichen material from little studied habitats and poorly known taxonomic groups which will become a relevant resource for further studies by researchers in Costa Rica, at our museum and for other collaborators across the world.

 

One personal research focus for me will be a comparison of the freshwater lichens in the Talamanca Mountains with those in streams of other tropical and temperate areas. For temperate areas lichens were shown to be valuable indicators of water level fluctuations and stream bed stability, but we still know to little on the species diversity and the distribution patterns of freshwater lichens in the tropics to make them useful tools for the assessment of streams in these areas as well.

 

A second area of interest is an assessment of the lichen diversity on rock outcrops and the light rich and open Paramo-vegetation at the highest elevations of the Talamanca Mountains. These habitat types cover huge areas in the South American Andes but occur in relative isolation and at a much smaller scale in Costa Rica, separated by large densely forested areas. Together with my research colleague Cecile Gueidan we want to find out how this isolation affects the diversity of lichens. This habitat type is also likely to be among the first to be affected by climate change.

 

What one piece of advice would you give someone going on field work for the first time?

Try to get in contact with local people, appreciate and follow their advice.

20120131-Costa-Rica-Valley-of-Silence-copyright-Natural-History-Museum.jpgIn February 2012 a team of 4 Natural History Museum botanists will be travelling to a remote area of tropical forest known as 'El Valle de Silencio' (The Valley of Silence) in Costa Rica. The team will be camping and collecting flowering plants, ferns, mosses, lichens and algae.

 

As part of the Museum’s Nature Live programme, I’m lucky enough be joining the trip and I’ll be sending back daily reports from Costa Rica in the form of blog posts, pictures and video.  If you'd like to get in touch with the field trip you can use the comments sections at the end of each blog.

 

For a chance to experience the trip come to the Attenborough Studio in the Museum on 11, 16 and 18 February for 12:30 or 14:30 to see a live video link to Costa Rica.
