Changing Perspectives in Conservation

Thu, 18 Dec 2014 12:15:44 +0000

Our views of the importance of nature and our place within have changed dramatically over the the last century, and the prevailing paradigm has profound influences on conservation from the science that is conducted to the policies that are enacted. In a recent perspectives piece for Science, GEE’s Professor Georgina Mace considered the impacts that […]

Function Over Form: Phenotypic Integration and the Evolution of the Mammalian Skull

Mon, 08 Dec 2014 14:05:52 +0000

Our bodies are more than just a collection of independent parts – they are complex, integrated systems that rely upon precise coordination in order to function properly. In order for a leg to function as a leg, the bones, muscles, ligaments, nerves and blood vessels must all work together as an integrated whole. This concept, […]

The Best of Both Worlds:Planning for Ecosystem Win-Wins

Sun, 16 Nov 2014 12:25:44 +0000

The normal and healthy function of ecosystems is not only of importance in conserving biodiversity, it is of utmost importance for human wellbeing as well. Ecosystems provide us with a wealth of valuable ecosystem services from food to clean water and fuel, without which our societies would crumble. However it is rare that only a […]

Life Aquatic: Diversity and Endemism in Freshwater Ecosystems

Thu, 06 Nov 2014 11:22:07 +0000

Freshwater ecosystems are ecologically important, providing a home to hundreds of thousands of species and offering us vital ecosystem servies. However, many freshwater species are currently threatened by habitat loss, pollution, disease and invasive species. Recent research from GEE indicates that freshwater species are at greater risk of extinction than terrestrial species. Using data on […]

Handicaps, Honesty and VisibilityWhy Are Ornaments Always Exaggerated?

Thu, 23 Oct 2014 13:30:30 +0000

Sexual selection is a form of natural selection that favours traits that increase mating success, often at the expense of survival. It is responsible for a huge variety of characteristics and behaviours we observe in nature, and most conspicuously, sexual selection explains the elaborate ornaments such as the antlers of red deer and the tail […]

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.
