Bone-eating worms and wood-eating bivalves: characterising the ecology of deep-sea organic falls from multiple ocean basins


Diva Amon

Department of Life Sciences, NHM and University of Southampton

Sir Neil Chalmers seminar room, Darwin Centre LG16 (below Attenborough studio)

Large organic inputs to the deep seafloor such as the remains of whales or pieces of wood are termed ‘organic-falls’ and are important sources of food, shelter and hard substrate in the deep sea. Despite over 30 years of research on these habitats, we still have only a basic understanding of their taxonomic composition and for some ocean basins, no natural or experimental studies have ever been conducted. The degree of connectivity between these isolated habitats, as well as how quickly organic matter is remineralised by specialist organic-fall fauna, such as bone-eating Osedax worms and wood-eating Xylophaga molluscs, are poorly known. My PhD research has tried to shed light on these topics resulting in the last three years spent undertaking some extraordinary tasks in a variety of locations: collecting whale bones and bone-eating worms from the Antarctic deep seafloor, cutting bones out of beached whales in Kent, sinking wood and whale bones on the Southwest Indian Ridge, diving to 2500 metres in a Japanese submersible, observing what happens when tiger sharks and whale bones meet in the Bahamas, and haggling over pig carcasses with a Jamaican butcher. All in the name of science! Today I will reminisce on a few of these adventures, as well as present results from the penultimate chapter of my thesis: Ecosystem function of the wood-boring genus, Xylophaga (Pholadidae, Bivalvia) revealed by X-ray micro-computed tomography. Wood deployments from two seamounts on the Southwest Indian Ridge were investigated in detail to examine the nature of intact Xylophaga borings, the comparative abundances and population size structures of the species, their rates of growth and their consumption rates of wood. Two more sets of samples from the Mid-Cayman Spreading Centre and the Tongue of the Ocean, Bahamas were also scanned. The wood at each deployment site was colonised by a different species of Xylophaga. This novel analysis has shown that an individual Xylophaga can bore between 0.235 and 0.606 cm3 of wood per year depending on the species, emphasising the importance of the genus Xylophaga with regard to wood remineralisation in the deep sea and its role as an ecosystem engineer.

Presentation of PhD results: impact on visitors of meeting scientists in Nature Live


Amy Seakins

Collaborative PhD between the Natural History Museum and King’s College London

Thursday 5 December
DC Seminar Room (underneath the Attenborough Studio) 10.00-11.00


This thesis explores the impacts of meeting research scientists on visitors to the Natural History Museum, London, from the visitors’ perspective. Firstly, the study aims to investigate whether meeting a scientist changes visitors’ identification of scientists, their perceptions of ‘who scientists are’ and what scientists are like, perhaps challenging previously encountered stereotypes of scientists. Secondly, the study looks at visitors’ identification with scientists, whether visitors become more interested in the life and work of the scientist, seeing science as personally relevant, and whether visitors make connections to the scientist. Through researching the impacts of interactions between visitors and scientists, this thesis adds to the literature aiming to increase science literacy and engagement, contributing to knowledge of how individuals can become more active, confident and interested in science as a part of their everyday lives.


Amy is about to submit her thesis so come and discuss her findings with her. They are of value to those who plan public engagement activities as well as those from Science who take part in education programmes and interact with visitors.

How to make a tapeworm


Pete Olson

The Natural History Museum, Dept. of Life Sciences, Div. of Parasites & Vectors


Wednesday 20 November 11:00
Sir Neil Chalmers seminar room, Darwin Centre LG16 (below Attenborough studio)

The evolution of parasitic flatworms represented a major departure from the free-living platyhelminth form, with each group evolving fundamentally different key adaptations toward increased fecundity (i.e. extreme r-selection). Such radical departures in morphology make homology assessment difficult if not impossible and hence we are working to elucidate the molecular signals that underpin their morphological evolution.


Using the beetle/rodent tapeworm Hymenolepis microstoma as a laboratory model of a strobilate (i.e. segmented) tapeworm, we now have not only a full catalog of its genes, but also transcriptome (i.e. expressed gene) samples from different regions of the body and ontogenetic stages. These genome-wide transcriptome profiles provide both qualitative and quantitative data on gene expression within a given sample, and through comparison we can thus identify which genes are up- or down-regulated throughout their complex life cycle. Among these we have selected the comparatively small number (~50) of 'developmental genes' (i.e. signalling and transcription factors) and have begun to survey their spatial expression patterns through whole-mount in situ hybridisation.


Results show both stereotyped and novel spatial patterns and allow us to associate the genes with organs, such as the ovaries, which prove to be an important source of developmental signals in tapeworms, just as they are in other animals including ourselves. These data provide a comprehensive picture of the factors governing tapeworm development and offer an effective means of identifying the 'hidden synapomophies' that underpin key innovations in form.

The boredom of belemnites: endoliths in belemnite guards from the Cretaceous Speeton Clay



Paul D. Taylor

Earth Sciences Department, Natural History Museum.


Tuesday 12 November- 4pm

Earth Sciences Seminar Room  (Basement, WEB 05, the previous Mineralogy Seminar Room)



The Early Cretaceous Speeton Clay Formation is renowned for its rich and diverse belemnite fauna. During October 2009 and March 2011 NHM field parties collected numerous examples of Speeton belemnites from the coastal exposures of the Speeton Clay south of Filey in East Yorkshire. These collections have been used in a research project, undertaken jointly with Consuelo Sendino and Museum volunteer Jane Barnbrook, on the previously unstudied biota of boring organisms that infested dead belemnite guards lying on the Cretaceous sea floor.


At least 15 ichnotaxa of borings can be recognized, ranging from brachiopod pedicle attachment traces (Podichnus), to rosette-like traces believed to have been made by foraminifera (Semidendrina), and putative fungal microborings (Orthogonum and Saccomorpha). The study of these endoliths can provide evidence for palaeoenvironmental conditions on the sea floor during deposition of the Speeton Clay.

Phylogenetics and evolution of some early and oddball plants


Sean Graham

University of British Columbia


Friday 8 November 11:00
Sir Neil Chalmers seminar room, Darwin Centre LG16 (below Attenborough studio)

My research group works on multiple problematic nodes in the plant Tree of Life. Here I focus on two major subjects from phylogenetic and evolutionary perspectives: (1) The 'early' aquatic flowering-plant family Hydatellaceae; (2) the mycoheterotophic plants, which are diverse lineages of non-photosynthetic plants that rely on fungi for their carbon budget.
