PREDICTS Project: Land-Use Change Doesn’t Impact All Biodiversity Equally

Mon, 13 Oct 2014 09:17:53 +0000

Humans are destroying, degrading and depleting our tropical forests at an alarming rate. Every minute, an area of Amazonian rainforest equivalent to 50 football pitches is cleared of its trees, vegetation and wildlife. Across the globe, tropical and sub-tropical forests are being cut down to make way for expanding towns and cities, for agricultural land […]

Calculated Risks: Foraging and Predator Avoidance in Rodents

Fri, 03 Oct 2014 10:07:08 +0000

Finding food is one of the most important tasks for any animal – most animal activity is focused on this job. But finding food usually involves some risks – leaving the safety of your burrow or nest to go out into a dangerous world full of predators, disease and natural hazards. Animals should therefore be […]

Applying Metabolic Scaling Laws to Predicting Extinction Risk

Thu, 25 Sep 2014 10:32:49 +0000

The Earth is warming. That much were are now certain of. A major challenge for scientists hoping to ameliorate the effect of this on biodiversity is to predict how temperature increases will affect populations. Predicting the responses of species living in complex ecosystems and heterogenous environments is a difficult task, but one starting point is […]

The Importance of Size in the Evolution of Complexity in Ants

Tue, 16 Sep 2014 10:14:37 +0000

Ants are amongst the most abundant and successful species on Earth. They live in complex, cooperative societies, construct elaborate homes and exhibit many of the hallmarks of our own society. Some ants farm crops, others tend livestock. Many species have a major impact on the ecosystems they live in, dispersing seeds, consuming huge quantities of […]

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 […]

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: ucbhpom@ucl.ac.uk)

Closing date: 10th May 2013.
