UrduA new study shows that wolves in Washington state are not having much of an impact on white-tailed deer, one of their primary prey. In a paper published June 18, scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available. Cougars were second in their impact. Wolves were a distant third.

Out of the frying pan: Coyotes, bobcats move into human-inhabited areas to avoid apex predators — only to be killed by people
In Washington state, the presence of two apex predators — wolves and cougars — drives two mesopredator species — bobcats and coyotes — into areas with higher levels of human activity, with deadly results for the mesopredators.
Study First to Explore ‘Walking’ Sharks on the Move in Early Life Stages
A newly-discovered walking shark that breaks all of the rules for survival is the focus of a first-of-its-kind study that examined differences in walking and swimming in neonate (newly-hatched) and juvenile walking sharks. Despite dissimilarities in body shapes – neonates have bulging bellies and juveniles are slender – the three aquatic gaits they use (slow-to-medium walking, fast-walking and swimming) did not differ. Kinematics between neonate and juvenile epaulette sharks did not alter during development.
