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 […]Read more...
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 […]

NERC PhD Studentship: Sexual selection, meiotic drive and fertility in stalk-eyed flies
Application Deadline: 10 May 2013
This project integrates field and laboratory based research on sexual selection. Stalk-eyed flies are a canonical example of sexual selection. In Teleopsis dalmanni, males have exaggerated eyespan and females show strong mate preferences for males with larger eyespan. Females have low fertility despite mating at high rates and exhibiting strong mate preference for particular males. Some populations harbour an X-linked meiotic drive system that results in female biased broods due to the degeneration of Y-bearing sperm. This project will further examine the inter-relationships between sexual selection, fertility and meiotic drive. The student will determine the frequency of drive in natural populations at established sites in Malaysia, the role of ecology and demography, and the consequences for the strength of sexual selection. In the laboratory they will exploit SNP and other genomic markers in order to reliably genotype individuals and progeny for meiotic drive, and study the association of meiotic drive with male eyespan and other aspects of male reproductive performance.
The UCL stalk-eyed fly research group is led by Prof. A. Pomiankowski and Prof. K. Fowler and studies multiple facets of the evolution of sexually selected traits. Given the project’s reliance on data collected from natural populations, the attributes of the successful applicant will include independence, initiative and enthusiasm in order to cope with the demands of field research. Note that applicants must have a minimum 2:1 BSc (or equivalent), preferably a Masters level degree, excellent numerate skills (computational and statistical), knowledge of population genetics and bioinformatics. Appropriate training will be provided by UCL. The studentship is funded by NERC and applicants need to satisfy NERC’s UK/EU eligibility requirements. It may be possible to fully fund EU candidates as well.
Applications should be sent as soon as possible, with cover letter, CV & contact details of two referees, to the primary supervisor Professor A. Pomiankowski (email: firstname.lastname@example.org)
Closing date: 10th May 2013.
