Researchers have transported two endangered freshwater mussel species from Pennsylvania to Illinois in an attempt to re-establish their populations in the western part of the Ohio River Basin.
Wild Asian elephants slink quietly away at the sound of a growling tiger, but trumpet and growl before retreating from leopard growls, researchers have found. The work could help Indian farmers protect their crops from marauding elephants and save the lives of both people and animals.
New research from Tufts University scientists shows that feral cats that undergo a vasectomy or hysterectomy could reduce a feral colony's numbers more effectively than the traditional approach of neutering. This may be because vasectomized cats retain reproductive hormones, in addition to not being able to reproduce, and therefore protect their turf from sexually intact competitors.
