An international team of paleontologists, which includes the University of Bristol, have identified the world's oldest lizard, providing key insight into the evolution of modern lizards and snakes.

Researchers at Tufts University have discovered that honey bees alter their diet of nutrients according to the season, particularly as winter approaches. A spike in calcium consumption in the fall, and high intake of potassium, help prepare the bees for colder months when they likely need those minerals to generate warmth through rapid muscle contractions....

A study led by the University of Liverpool and the Centre for Ecology & Hydrology (CEH) has found that parasites affect flight ability of wild seabirds, which may make it harder for them to raise chicks.

It's a puzzle that has confounded biologists for centuries: the earth's tropical regions are home to an enormous variety of plant and animal species, but as you travel north or south, away from the equator, the level of diversity dwindles.

Scientists have developed a new approach to understanding animal preferences, and the findings could provide greater insight into decision-making in humans.

A new doctoral thesis from Lund University in Sweden shows how fruit flies use their sense of smell and humidity to find food, avoid dehydration and discover the best place to lay their eggs -- in overripe marula fruits. Faeces from herbivores are also suitable, but the flies reject carnivore excrement.
