A recent paper by scientists from Wits University in South Africa shows how creative fire management can increase habitat for wildebeest and other grazing animals in national parks.

Study looks at why ring-tailed lemurs raise a stink when they flirt with potential mates
November 20, 2017 08:15 AM - University of Toronto

A University of Toronto study finds that a unique ritual performed by male ring-tailed lemurs may come at a significant physical cost, but it likely helps their chances in securing a mate.

Ring-tailed lemurs are Strepsirrhines, a sub-order of primates who share a common ancestor with humans. They are very social animals, living in large groups with females dominating the group. Like other lemurs, they huddle in large groups in order to keep warm and maintain social bonds, with lower ranking males often excluded.

Species in the North are More Vulnerable to Climate Change

Acclimation means the ability of both animals and plants to adjust their physiology when it gets hotter or colder. In this way, individual organs are able to interact effectively and various processes in the body function optimally in varying conditions.

Mutated frog gene repels predators

Post-doctoral researcher Andrés Posso-Terranova and his former supervisor José Andrés have found evidence that a single gene called MC1R controls the deep black color on the skin of these poisonous frogs. The researchers have found that the disruption of the gene is responsible for the black blobs and stripes. Their results have been published this week in the international journal Evolution.

Pesticides significantly reduce the number of pollen grains a bumblebee is able to collect, a new University of Stirling study has found.

Team Finds First Wild Alligator Snapping Turtle in Illinois Since 1984
November 13, 2017 11:48 AM - University of Illinois at Urbana-Champaign

Researchers report the first sighting in 30 years of a wild alligator snapping turtle in Illinois. The discovery may be a sign of hope for this state-endangered species, or the animal could be the last of its kind to have survived in Illinois without human intervention, the researchers say.

York University research shows insecticide-laden seeds can disorient migrating songbirds
November 13, 2017 08:32 AM - York University

Songbirds exposed to widely used insecticides during migration pit stops on farmland could lose significant body weight and become disoriented, research by York University and the University of Saskatchewan (U. of S.) has found.

The researchers exposed white-crowned sparrows on spring migration to realistic doses of two different insecticides – imidacloprid, a neonicotinoid, and chlorpyrifos, an organophosphate – to see the effects on migratory activity, orientation and body mass.
