Rare video captures following and biting courtship behavior in elusive whale sharks
Courtship and procreative behavior in many species of elasmobranchs—cartilaginous fish including rays, sawfish, sharks, and skates—may include following and biting. However, there has been little research on procreative ...
Recreational trails disturb grizzly bears and wolves more than expected
Human recreation on mountain trails is displacing grizzly bears and wolves from their natural habitats, even when the trails are hundreds of meters away, according to a new study from the University of Alberta. The research ...
