Exploring the natural enemies of insect pests

A method of investigating whether aphid pests have been targeted by their gruesome enemies could shed new light on how farmland organisms interact, and potentially help protect important food crops.

DNA from fossils reveal the origin of the Norwegian lemming

A new ancient DNA study shows that the Norwegian lemming has a unique history. In contrast to other mammals in Fennoscandia, the Norwegian lemming may have survived the last Ice Age in the far north, sealed off from the rest ...

Dry future climate could reduce orchid bee habitat

(Phys.org) —During Pleistocene era climate changes, neotropical orchid bees that relied on year-round warm, wet weather found their habitats reduced by 30 to 50 percent, according to a Cornell study that used computer models ...

Novel genes determine division of labor in insect societies

Novel or highly modified genes play a major role in the development of the different castes within ant colonies. Evolutionary biologists at Johannes Gutenberg University Mainz (JGU) came to this conclusion in a recent gene ...

The molecular clock of the common buzzard

Be it hibernation or the routes of migratory birds: all animal behaviour that is subject to annual rhythms is controlled by a molecular clock. Although this has been known for a long time, in many cases it is still unclear ...
