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 […]

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 […]

GEE PhD student publishes an exciting first author paper in JAMA

1 March 2011

GEE PhD student Laura Horsfall publishes an exciting first author paper in the Journal of the American Medical Association (JAMA) entitled 'Serum Bilirubin and Risk of Respiratory Disease and Death'; this complements a genetic paper which came out last week in the Annals of Human Genetics and which features on the front cover.

Laura J. Horsfall, M.Sc., of University College London, and colleagues examined the association between serum bilirubin levels and the incidence of chronic obstructive pulmonary disease (COPD), lung cancer and all-cause death in a large population-based group of patients from the United Kingdom. The study included 504,206 adults from a U.K. primary care research database (the Health Improvement Network) with levels of serum bilirubin recorded between January 1988 and December 2008.  More
