We have investigated if it is a general property of the brain’s circadian clock to recognize social interactions as external time givers. Sociosexual interactions with the opposite sex are universal, prevalent even in the lives of solitary animals. […]

Habitat fragmentation prevents species from tracking climate change

Climate changeaffectsbiodiversity globally, by forcing species to shift their distribution to track the changes in temperature. An international collaboration between scientists from France, Sweden, the Netherlands and Finland shows, in an article published in the journal Ecology Letters,that habitat fragmentation caused by human activity affects distribution shifts in butterfly species and, hence, their capacity to cope with climate change.
