As part of the Annual NHM Integrated Pest Management Awareness

   

Thursday 26th April 2012

2.30pm - 4.00pm

Flett Lecture Theatre, NHM, South Kensington London, SW7 5BD

 

Armando Mendez, Suzanne Ryder and David A. Smith from the Natural History Museum


Regular trapping and periodical inspections alerted Natural History Museum’s IPM Group to a rise in the number of webbing clothes moths, Tineola bisselliella, in the Museum’s Mammal corridor in late 2010.  This awareness led to the combined use of pheromone lure traps and a new visual display of trapping data.  This was used with the collections management system KE-EMu  to closely follow the evolution of the infestation.

 

At the time, a rodent infestation was discovered in a Museum themed gallery, quite distant from the original moth infestation. However, in this rodent location, Tineola moths were also discovered in textile materials contaminated by rodents. The use of pheromone traps and digital cameras proved that both infestations were linked and that there was a strong possibility that the moths were thriving in the welcoming environment created by the rodents. The pests were using under-floor ventilation ducts to move around the Museum’s public galleries, posing a threat to the Mammal specimens on display in those galleries.

 

To deal with the problems, the Museum’s IPM group coordinated the efforts of several teams to apply remedies based on IPM principles and best practice.Housekeeping, Design & Installation and Estates maintenance teams are working together, coordinated by the IPM group, to control this infestation. A trial of a new pheromone distraction product is also underway.

 

  • The seminar is open to all museum professionals. We welcome colleagues from other institutions who would find the seminar of interest. There is no booking fee and only large parties need to notify the organiser for catering purposes.
  • NHM staff from Science Group and Public Engagement Group are encouraged to attend, whether managers, collections management staff or those who work with and use collections or manage staff who work with collections.

 

Tea and coffee will be available in the seminar room lobby area after the talk.

 

Suggestions for seminar speakers are always most welcome. Please contact the organiser Clare Valentine (c.valentine@nhm.ac.uk

Zoology Seminar


Integrating Molecules and Morphology: Consensus or Conflict in the Symbiotic Copepods?

 

Rony HUYS
Department of Zoology, NHM

 

TUESDAY 17th April, 12pm

Neil Chalmers Science Seminar Room (DC.LG16)

 


No group of plants or animals on Earth exhibits the range of morphological diversity as seen among the extant Crustacea. This structural disparity is best demonstrated by the symbiotic Copepoda. Given their moderately high host specificity in conjunction with the incredible spectrum of potential marine hosts, it is highly conceivable that parasitic copepods significantly outnumber their free-living counterparts in species diversity. Their successful colonization or utilization of virtually every metazoan phylum has generated a great diversity in copepod body morphology, which is arguably unparalleled among the Crustacea. For example, some highly modified copepods such as the polychaete-associated Herpyllobiidae and Melinnacheridae lack any external trace that could positively identify their crustacean affinity and their divergent body plans defy any attempts to place them in a higher level classification on morphological grounds alone. Other families such as the Monstrillidae and Thaumatopsyllidae demonstrate how extremely powerful natural selection can be in shaping morphology to meet functional needs so that distantly related taxa may appear uncannily similar. Small subunit ribosomal sequence data (18S rDNA) can help resolving some of the controversial issues that had reached a temporary impasse in the phylogeny and classification of the symbiotic copepods, such as the placement of the Monstrillidae and Thaumatopsyllidae, the paraphyly of the Cyclopoida and the origin of parasitism in the freshwater environment. Examples will be given that demonstrate the usefulness of such data in the classification of highly transformed and morphologically reduced taxa, the inference of colonization events and the placement of incertae sedis known exclusively from juvenile stages. I will present evidence that illustrates how the use of 18S sequence data can lead to the discovery of previously overlooked morphological characters and how they can potentially impact on the ordinal level classification of the Copepoda.

Taking a deep breath: bones, air sacs and the evolution of archosaur respiratory systems

 

Dr. Paul Barrett, Department of Palaeontology, NHM

 

Thursday 12th April
Neil Chalmers Seminar Room, DC2,

16:00

 

 

Birds have highly specialised respiratory systems that involve unidirectional movement of air through stiff, small lungs and a complex system of associated air sacs. These air sacs invade many postcranial skeletal elements during development, leaving characteristic traces. Similar features are present in many saurischian dinosaurs, and it seems likely that the accompanying soft-tissue features were present in these animals too. More vexed is the question of how ancient these features are and whether they had a wider distribution among archosaurs. A survey of numerous extinct and extant archosaurs shows unambiguous evidence for an ancient origin of these bird-like features, with their presence in many bird-line archosaurs. The possession of air sacs in crocodile-line archosaurs is more difficult to determine, but some features of the bony anatomy, and recently published work on the physiology of living crocodiles, suggests that many features formerly considered to be unique to birds actually had a much wider distribution. This has several interesting implications for the evolution of activity levels and locomotion in both bird- and croc-line archosaurs.

5th Annual Palaeontographical Society Address

 

Virtual Fossils and the Herefordshire Lagerstatte

 

Dr Mark Sutton
Imperial College, London

 

Wednesday, April 18th 4.15 pm
Flett Lecture Theatre, Natural History Museum

 

 

Three-dimensional soft-bodied fossils represent some of the richest sources of palaeobiological data available, but are often difficult to work with using conventional techniques. Various technologies, both new and old, now exist to recover 3D morphology from such material. Most of these are tomographic in nature, based around the recovery of parallel 'slice images' through the fossil, either directly through serial grinding or sawing, or indirectly through scanning techniques. Reconstruction of tomographic datasets as three-dimensional interactive ‘virtual fossils’ on a computer screen not only provides a practical way to study difficult material, but brings a host of benefits along with it.

The Herefordshire Lagerstätte is a Silurian-aged deposit preserving a range of marine invertebrates in three-dimensions, complete with soft-tissues. These are essentially impossible to extract or image in their entirety without the use of tomographic techniques. The deposit hence provides a testbed and showcase for the ‘virtual fossil’ paradigm; prior to the advent of these techniques its significance was unclear, while after 12 years of ‘virtual’ study it is arguably the most significant invertebrate fossil locality known from Britain. Studies having yielded a wealth of new and often rather unexpected anatomical information on molluscs, echinoderms, brachiopods, polychaetes, and most especially arthropods. New finds discussed in this lecture include a chiton-like mollusc, a horseshoe-crab-like arthropod, and a potential stem-group Euarthropod, but further spectacular animals continue to emerge.

All welcome. Tea/coffee available in the Flett Foyer from 3.45 pm onwards

Quantifying Holocene sea-level change in the UK

 

Dr. Tom Hill

Department of Palaeontology, NHM

 

THURSDAY 15th March
Neil Chalmers Seminar Room, DC2,

16:00 - 17:00

 

 

When comparing mid twentieth century measurements of annual sea-level rise (c. 1.8mm/yr) to the current observed rate of c. 3.3mm/yr, there is clear evidence for rising sea levels in response to human-induced global warming. But as tide gauge records are only available for the last few centuries, how do we know such changes are indeed human-induced or in fact simply part of natural cycles of sea-level change that have prevailed for hundreds and thousands of years?

 

Biostratigraphic analyses of Holocene coastal sediments from around the UK offer one route through which the elevation of past sea level can be quantified. In southwest England, extensive sequences of interbedded estuarine silts and freshwater peats have accumulated within the Severn Estuary basin, suitable for sedimentary coring and subsequent laboratory analyses. Preserved in abundance are diatoms, unicellular microscopic algae that live in all subaqueous environments, requiring specific environmental conditions to survive. By analysing the diatom assemblages at different depths within the sediment cores and relating the species abundance and diversity encountered to those present along the contemporary Severn Estuary coastline, it was possible to quantify the palaeo-elevation at which the estuarine sediments were deposited, relative to past sea level. Such information yields an insight into the way sea level has changed during the last 10,000 yrs and complements other, more traditional techniques of sea-level reconstruction.

Parasites and Food Webs

 

Kevin LAFFERTY

Department of Ecology, Evolution and Marine Biology, University of California, Santa Barbara

 

TUESDAY 27th March,

Neil Chalmers Science Seminar Room (DC.LG16)

12:00 -13:00

 

 

 

Ecologists use food webs to help make sense of the complexity of the natural world and the food web has become the key conceptual framework for ecology. Recently, parasitologists have pointed out that parasites make up half of biodiversity, yet are almost never included in food webs.  Here, I will discuss how food webs affect parasites, how parasites affect predator-prey interactions, how parasites affect the complexity of food webs and finally what parasites can tell us about ecological complexity. I argue that most of what we have learned about food webs, and therefore ecology, is incomplete without a full consideration of parasites.

Collection Management Seminar

 

Swop Shop: from one dinosaur to the next!   Museum Professionals skill and knowledge sharing

 

Speakers: 
Rachel Mackay, Visitor Experience Manager, NHM and LMG Share London Representative
Nancy Groves, Editor, The Guardian’s Culture Professionals Network
Julie Reynolds, Blogger, London Museums Group

 

WEDNESDAY 21st March, Flett Lecture Theatre, NHM, South Kensington

2.30pm-4.00pm

 


Synopsis:
Established in 2006, London Museums Group (LMG) is the representative group of all museums and the museum workforce in the Greater London area.  All individuals working in and for museums and related organisations in London, whether paid or unpaid, whether directly or as freelancers, can become members of the wider London Museums Group.


LMG consultation in the sector has proved a real hunger for a self-sustaining forum where museum professionals can share skills, knowledge and expertise.  London Museums Group’s Share London is an exciting new scheme that hopes to provide the answer. The scheme aims to support professional and personal development and make the excellent skills sharing that already goes on in the sector more accessible. We hope everyone involved – whether receiving support or giving it – will benefit from developing new skills and making new contacts.

Rachel Mackay, Share London’s Representative will introduce LMG and Share London and show how you can register offers of support and needs through the web site. Offers can be anything from stewarding at events or offering unused equipment to offering workshops, job shadowing and mentoring.


Judy Lindsay, Chair, of LMG published a blog on Share London for the new Cultural Professionals Network Guardian blog space: Museums sharing (with) a passion, and Nancy Groves the Editor will introduce this sharing network of creative professionals and give an insight into how museums can approach the culture journalists at the main Guardian newspaper.


To conclude, LMG Blogger in Residence Julie Reynolds and University of Manchester Professional Doctorate Museum Studies Student, will share human narratives of a skill sharing scheme that involved Louise Tomsett, Curator, Mammal Group, Zoology Department at the National History Museum and Milly Farrell, Curator, Odontological Collection at the Hunterian Museum [housed at the Royal College of Surgeons). Julie’s research focuses on the hidden knowledge around collections and human narratives and the talk will highlight the skills and knowledge shared, the benefits and challenges of the scheme through the curator’s voices and objects in their collections.

The seminar is open to all museum professionals.

 

 

Tea and coffee will be available in the seminar room lobby area after the talk.

 

 

Suggestions for seminar speakers are always most welcome. Please contact the organiser Clare Valentine (c.valentine@nhm.ac.uk

Structural Weakening of Corralline Algae Skeleton in Response to Ocean Acidification

 

Federica RAGAZZOLA
School of Earth Science, University of Bristol

 

TUESDAY 6th March,

Neil Chalmers Science Seminar Room (DC.LG16)

12:00 -13:00

 

Since the beginning of the industrial revolution, carbon dioxide concentrations in the atmosphere have risen by over 100 μatm (from 280 μatm to 390 μatm) due to anthropogenic input. The ocean has absorbed about one-third of the anthropogenically derived CO2 which has resulted in a lowering of the carbonate saturation and a reduction of the average global surface ocean pH by almost 0.15 units, a process termed "ocean acidification". These chemical changes are suggested to have direct implications for physiological processes such as photosynthesis, calcification or internal pH regulation in a wide range of marine organisms. To test these effects on marine calcifiers living in high latitude, the coralline alga Lithothamnion glaciale was cultured for 3 months at different pCO2 concentrations. Here we show continued calcification of L. glaciale in undersaturated/high pCO2 conditions but with major changes in the ultrastructure leading to an increase in the total strain energy of nearly an order of magnitude and an uneven distribution of the stress inside the skeleton. This weakening of the structure is likely to reduce the ability of the alga to resist boring by predators and wave energy with severe consequences to the benthic community structure.

Chert on the beach

 

Dr. Lil Stevens,

Department of Palaeontology, NHM

 

Thursday 1st March
Neil Chalmers Seminar Room, DC2,

16:00 - 17:00

 

 

 

In 2004 an amateur collector found a dull brown cobble on the beach at Sandsend, part of the Yorkshire Jurassic coast. Hammer at the ready, he broke the cobble into eleven pieces and looked into its interior. It was probably raining, which would have helped him to see small pieces of fossilised plants preserved within the chert, including what looked like reproductive structures. The cobble made its way to Birmingham University and after many months of sectioning and polishing, there began to emerge the most beautifully preserved Palaeozoic plant and crustacean remains I have ever seen.

Contained in the cobble were vegetative and reproductive fragments of an arborescent lycopsid with cellular preservation. The cone fragments were described as Flemingites arcuatus sp. nov. and analyses confirmed a provisional assignment to Paralycopodites stem genus. Associated with the plant remains were many small univalve crustaceans described as Ebullitiocaris elatus sp. nov., the same genus as those found in the Devonian Rhynie chert from Scotland. Extremely rarely for this age of fossil, both internal organs and appendages are visible and show a long morphological stasis and even some features still retained by modern Cladocera.

The cobble has preserved organisms of mid to late Carboniferous age and is therefore ex-situ. Chert content analysis and the level and mode of preservation of the fossils suggests not necessarily a hot spring environment, but a swamp certainly influenced by some sort of hydrothermal volcanic activity that caused rapid solidification. Comparison with other cherts has not helped to narrow down the original locality and it is thought that although the cobble was probably transported south east by glacial activity, it is also possible that it was dumped as ballast on the busy shipping routes around north east Britain, and so could have originated from almost anywhere in the world.

The Mysterious World of Vampire Amoebae and  Plasmodiophorid Plant Parasites

Sigrid NEUHAUSER & Cédric  BERNEY
Department of Zoology, NHM

Vampire amoebae  (Vampyrellida) and plasmodiophorid plant parasites (Phytomyxea) have been known  since the second half of the XIXth century, yet have been given very little  attention up to now in spite of their fascinating biology. The taxonomic  position of both groups has been much debated for over a century, but recent  molecular work showed them to be sister lineages within the eukaryotic  supergroup Rhizaria. From their common ancestor, the Vampyrellida evolved to  become super-predators of algae, fungi and other microorganisms in all marine  and terrestrial microbial ecosystems, with some species adopting a peculiar mode  of feeding that earned them the name of vampire amoebae. In contrast, the  Phytomyxea evolved to become obligate, endobiotic parasites of higher plants,  diatoms, brown algae and oomycetes. Members of this group can cause devastating  and significant plant diseases (e.g. Plasmodiophora brassicae causing  clubroot disease), while others will spend their life hidden inside their hosts  without causing any visible symptoms. As part of our research group’s focus on  the biodiversity, evolution, and ecological importance of poorly known members  of the Rhizaria, we will present some of our results and illustrate the  enigmatic nature and contrasting lifestyles of vampire amoebae and  plasmodiophorid plant parasites.

Australia Home to the Oldest Continual Culture

 

Emma Loban and Carole Christopherson

Human Remains Unit, Department of Palaeontology, NHM

 

Thursday 16th February
Neil Chalmers Seminar Room, DC2, NHM

16:00 - 17:00

 

 

 

For 2000 generations Australia has been home to the oldest continuing human culture in history. For over 40,000 years Indigenous people have explored, discovered, named and lived on the entire land mass and islands of Australia.

 

There are two distinct Indigenous groups of Australia; Aboriginal and Torres Strait Islanders.

 

Aboriginal people of Australia are not all the same and there is not one language or culture. Within Aboriginal Australia are hundreds of distinctly different cultures that continue to exist today.  Who are the Yolgnu, Wararkbi, Tiwi, Walpiri, Warramungu, Arrente, Kamilori?

 

Torres Strait Islander people are a minority group, within a minority group.  What makes this group of people unique? How many islands make up the gateway to Australia? What are their connections to the Australian mainland?

 

Although two groups of distinct peoples, what are the similarities between Aboriginal and Torres Strait Islanders? Join us in a presentation about Indigenous Australia and the Diversity of people. Carol and Emma will explore shared history, geography, linguistics, kinship, world views, Indigenous perspectives on repatriation and their work here at The Natural History Museum.

Collection Management Seminar

 

 

Are we there yet? Maps and geographic information at the NHM : findings of the Library Map Collections Review

When?

 

April Carlucci

Library and Archives, NHM

 

Thursday 23rd February 2012

Flett Lecture Theatre, NHM, South Kensington

2.30pm-4.00pm

 

 

Synopsis:
With more than twenty years experience working with maps in libraries, April joined the NHM in June 2011 to conduct a review of the Library’s map collections, as part of the Library’s ongoing strategy work, and now feeding into the Director of Science’s  working groups. The remit of the Review is to assess the Library’s current collections; talk with Science and Public Engagement colleagues about their needs for geographic information and how those needs are being met; to place the Museum’s map collections in their national and international contexts; and to identify opportunities for partnerships, cooperative ventures and revenue generation. April discusses her findings, including the remarkably consistent needs for geographic information across the Science departments; what other natural history museums are doing in this area; what resources are being missed; and the risks to the collections, research and engaging the public that are being taken with the current approach. The Review concludes in March, and, as a work still in progress, she is eager to hear comments  on her findings from all those in the Museum who use cartographic and geographic information in their work.

 

The seminar is open to all NHM staff  and we also welcome colleagues from other institutions who would find the seminar of interest. There is no booking fee and only large parties need to notify the organiser for catering purposes.


Tea and coffee will be available in the seminar room lobby area after the talk.

 

Suggestions for seminar speakers are always most welcome. Please contact the organiser Clare Valentine (c.valentine@nhm.ac.uk)

Palaeontology Department Seminar

 

Hunting down Quaternary mammals on Eastern Mediterranean islands: surveying Crete for seven years

Thursday 9th February
Neil Chalmers Seminar Room, DC2, NHM

In 1745, Pococke reported the first fossil bone findings from Crete Island, discovered in the Agios Georgios Cave (Akrotiri peninsula) in Western Crete. For more than 250 years the island has been widely acknowledged as an important and popular place for the study of endemic island faunas. All these years, several workers have surveyed the island, discovering tens of fossiliferous Pleistocene localities. Until 2000, 75 mammal localities had been reported from the island. In the last 12 years 37 new localities have been discovered, raising the number of known localities to 112. The vast majority of these localities were discovered by systematic surveying on the Island by the Palaeontology group of the Natural History Museum of Crete. We employed caving and climbing techniques to access deep potholes and rocky cliffs and getting ‘extreme’ helped us discover new localities. Fossiliferous localities were discovered on southern and mountainous areas of Central Crete, where there were no previous reports. The new localities brought new findings such as the new Middle Pleistocene deer from Katharo plato and a Middle Pleistocene otter from Cape Malekas. Therefore, new localities provide new data and thus the Quaternary history of the Island needs to be reviewed and rewritten.
