Study provides insights into birds' migration routes

By tracking hybrids between songbird species, investigators have found that migration routes are under genetic control and could be preventing interbreeding. The research, which is published in Ecology Letters, was conducted ...

Veeries stay mum at night to avoid becoming owl dinner

"When the sun hits the ground and the owl's been around, veeries nary make a sound." It's a familiar quotation you've never heard before, but one buoyed up as a modern truism thanks to recent research conducted in part by ...

Biological fitness trumps other traits in mating game

When a new species emerges following adaptive changes to its local environment, the process of choosing a mate can help protect the new species' genetic identity and increase the likelihood of its survival. But of the many ...

Sexual selection in the sea

Biologists have uncovered new insights into how the male sexual behaviour of the peculiar southern bottletail squid is primed to produce the greatest number of offspring.
