Frazer on climate change & insects – AGU video

Frazer Matthews-Bird’s video on his PhD research examining long-term (>50 year) climate change from fossil insects (chironomids) has been shortlisted for the American Geophysical Union (AGU) student competition prize. Please watch Frazer’s video and “Like”; the most liked video will win free entry into the AGU Fall meeting 2014.

Three new videos on the Ecology of the Past Youtube channel

We’ve got a bumper crop of palaeoecological film making for you today, with three videos uploaded to our very own ‘Ecology of the Past’ Youtube channel. We’ve got an interview with Will Gosling, talking about the Bosumtwi pollen chemistry project and his own background and career (it’s a timely and somewhat poignant addition to the channel, because this is Will’s last day at The Open University before heading off to Amsterdam). Also posted are research presentations by Frazer Bird and Hayley Keen, which were filmed during the PhD student conference on 21st May. For the first time at the Open University these presentations were carried out in the Three Minute Thesis (3MT®) format.

Heslop-Harrison, J. (1979) Aspects of the structure, cytochemistry and germination of the pollen of Rye (Secale cereale L.). Annals of Botany, 44, 1-47.
Summary (Adele): Sometimes, the old ones are the best, and this behemoth of a paper contains a huge amount of useful information on the chemical structure and development of Rye pollen grains. As I am working on the chemistry of grass pollen at the moment, it is incredibly useful to know that this sort of information exists and can be used to inform both my experimental protocol and interpretations.

Summary (Hayley): GPS data used to detect plate boundary convergence, subduction and collision within the north west of South America. GPS data between 1991 and 1998 was used to work out rates of movement for plates.
