New research published in eNeuro has identified natural, plant-derived that repel fire ants. These compounds, including one found in cinnamon, work by activating a type of ion channel highly expressed in the antennae and leg of one of the world's most invasive insect species.
Native to South America, the red imported fire ant (Solenopsis invicta) has...
Male cichlids that are constantly threatened by predators grow faster and postpone the full expression of conspicuous breeding coloration for longer. This is shown by a study by biologists from the University of Bonn. Thereby, the animals reduce their risk of becoming prey. However, at the peak of their sexual maturity the animals give up...
A new study finds polar bears in the wild have higher metabolic rates than previously thought, and as climate change alters their environment a growing number of bears are unable to catch enough prey to meet their energy needs.
The study, published February 2 in Science, reveals the physiological mechanisms behind observed declines in polar bear...
