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 […]

Inaugural lecture date for three GEE professors

4 April 2011

We are pleased to announce that our three colleagues:  Jürg Bähler (Professor of Cellular Systems Biology), Max Telford (Professor of Zoology) and Kevin Fowler (Professor of Evolutionary Biology) gave their Inaugural Lectures on Wednesday 8 June 2011 starting at 5pm, in the Darwin Lecture Theatre, followed by a Celebratory Reception in the Wilkins JBR, Wilkins Building.

Prof Jürg Bähler's lecture was entitled: 'Messing about with yeast'.

Prof Max Telford's lecture was entitled:  'The Diet of Worms and other stories from the evolution of the animals'.

Prof Kevin Fowler's lecture was entitled:  'Sex, stalks and flies'.

Abstracts and photos taken at the event are below.

'Messing about with yeast'

Prof Jürg Bähler

Abstract

This may sound sad, but I have worked with fission yeast throughout my scientific career, first on chromosome pairing as a student in Switzerland, then on cell shape as a postdoc in America and in England, where I got stuck. After becoming independent in 2000, I embraced genomics and started to analyse gene expression at a global level (but yet again, with fission yeast). We are now continuing our global research on the regulation, function and evolution of genomes at London’s Global University.

'The Diet of Worms and other stories from the evolution of the animals'

Prof Max Telford

Abstract

My research attempts to further our understanding of the evolution of the great diversity of animals - from lowly sponges and jelly fish to the many phlya of worms,  insects, molluscs and vertebrates.

Underlying all studies of animal evolution is a tree describing the evolutionary relationships between the different groups and much of my research  has involved refining the evolutionary tree of the animals.

My doctoral work was on a phylum of worms called the arrow worms which share features of embryology with a major division of the animals called the deuterostomes. The evolution of the deuterostomes has a special interest  for humans as we vertebrates, along with starfish, sea urchins and acorn worms, are part of this group.  

My doctoral work showed the arrow worms are not deuterostomes with the implication that the characters they share are either more ancient than either group or have evolved more than once. 

More recently, my group has shown another very undeuterostome-like group of flatworms - Xenoturbella - ARE deuterostomes. This surprising result tells us that these simple worms are our close relatives and that they must have lost much of the complexity of our common ancestor.

Our plan now is to try to understand   how Xenoturbella and its kin have lost these advanced features by looking at its complete genomic DNA sequence.

'Sex, stalks and flies'

Prof Kevin Fowler

Abstract

Throughout my research career, my twin obsessions have been evolutionary biology and insects. My doctoral and postdoctoral studies used fruitflies to focus on diverse topics including the evolution of body size, costs of reproduction and the consequences of population bottlenecks. Since coming to UCL in 1994, I have become increasingly devoted to studying the evolution of ornamental traits, using stalk-eyed flies. These charismatic creatures, in which the eyes and antennae are borne at the end of lateral head projections (eyestalks), have proven to be excellent model organisms for the study of multiple aspects of sexual selection. I will review key findings from a dual perspective on the attributes of the ornamental trait (male eyespan) and on female mate preference for males of exaggerated eyespan.
