Unique study of isolated bobcat population confirms accuracy of extinction model
The reintroduction of 32 bobcats to an island off the coast of Georgia more than three decades ago created an ideal experiment to examine the accuracy of a genetic-modeling technique that predicts extinction of isolated wildlife populations.

Levels of stress hormone in saliva of newborn deer fawns may predict mortality
The first-ever study of the levels of the stress hormone cortisol in the saliva of newborn white-tailed deer fawns yielded thought-provoking results that have Penn State researchers suggesting predation is not the only thing in the wild killing fawns.

Penn State researcher defends deer antler point harvest restrictions
For more than 80 years, young Pennsylvania bucks have been protected by an antler point restriction banning the harvest of deer with spikes shorter than 3 inches. In the last 20 years, additional antler restrictions were imposed to ensure that male deer live long enough to breed.

Why knowing the science behind the rut can help bowhunters this season
The rut, the mating period for white-tailed deer, is upon us. It is the time of year that bowhunters look forward to, beginning in late October and lasting about a month.
