Understanding Catfish Colonisation and Diversification in The Great African Lakes

Fri, 05 Sep 2014 10:29:42 +0000

Why some regions or habitats contain vast, diverse communities of species, whilst others contain only relatively few species, continues to be the subject of scientific research attempting to understand the processes and conditions that allow and adaptive radiation. The Great African Lakes exist as freshwater ‘islands’, with spectacularly high levels of biodiversity and endemism. They […]

Sex Differentiation Begins During Early Development

Wed, 27 Aug 2014 14:04:57 +0000

Males and females look different from each other, and these sexual dimorphisms are the result, largely, of sex differences in the expression of certain genes. Typically, scientists have studied sexual dimorphism in sexually mature adult animals, as this is the lifestage where differences are most apparent. However, many sex-specific phenotypes arise from sex-biased development, so […]

Extinction and Species Declines:Defaunation in the Anthropocene

Mon, 18 Aug 2014 10:35:52 +0000

We are in the grips of a mass extinction. There have been mass extinctions throughout evolutionary history, what makes this one different is that we’re the ones causing it. A recent review paper from GEE’s Dr Ben Collen discusses the current loss of biodiversity and suggests that our main concerns are species and population declines, […]

Evolving Endemism in East Africa’s Sky Islands

Fri, 08 Aug 2014 14:16:32 +0000

The World’s biodiversity is not evenly distributed. Some regions are hot spots for species richness, and biologists have been trying better to understand why these regions are special and what drives evolution and diversification. A recent paper by GEE’s Dr Julia Day and recent PhD graduate Dr Siobhan Cox, investigated the diversification of White-Eye Birds […]

Predicting Extinction Risk:The Importance of Life History and Demography

Mon, 28 Jul 2014 14:46:17 +0000

The changing climate is no longer simply a concern for the future, it is a reality. Understanding how the biodiversity that we share our planet with will respond to climate change is a key step in developing long-term strategies to conserve it. Recent research by UCL CBER’s Dr Richard Pearson identifies the key characteristics that […]

GEE / UGI Researcher, Garrett Hellenthal, awarded BBSRC New Investigator Award

28 May 2014

Garrett Hellenthal

The aim of the BBSRC New Investigator Award is to assist newly employed university lecturers, and researchers at BBSRC-sponsored, and certain other research institutes in their first open-ended appointments to obtain their first research grant.

Garrett has received £500K in funding, including a three-year post-doctoral researcher. He will be working in collaboration with GEE Professors David Balding and Mark Thomas, Dr Neil Bradman and researchers from Addis Ababa University, Cambridge and Harvard.  The project entitled "Evolutionary processes shaping genetic structure in Ethiopia and the Sudans" is a three year project that involves genotyping 2,000 individuals (from samples stored at UCL) to learn about the ancestral history of >90 different ethnic/regional groups from Ethiopia and the Sudans.

The project will develop novel statistical methodology to identify which geographical and sociological (e.g. language, religion) features contribute most to genetic diversity -- or act as barriers to gene flow -- among different human groups. The project will also assess genetic diversity in this part of Africa in relation to the rest of the world, helping to dissect the initial migrations of early humans out of Africa when colonizing the rest of the world.
