Policies that encourage hunters to go after male polar bears in order to conserve females, could make it harder for the animals to find mates. University of Alberta researchers determined there is a critical threshold in the male-to-female ratio. Below it, their model predicts a sudden and rapid collapse in fertilization rates.
Wind energy is one of the fastest growing sectors of the energy industry, but not without environmental consequences. Nocturnally active birds and bats have become prey to turbines, yet little guidance could be found for assessing impacts of wind energy on this group until now. A new article published in the latest issue of The Journal of Wildlife Management gives guidance about the methods and metrics of this subject.
The United States Fish and Wildlife Service (USFWS) was recently petitioned to list the wolverine as threatened or endangered under the federal Endangered Species Act. As a valuable tool for the USFWS to evaluate this potential listing, a special section of eight papers discusses the wolverine's current challenges as well as its historical distribution, habitat relations and interactions with humans.

The paper is published in the latest issue of Wilderness and Environmental Medicine.
Tufts biologists have discovered a dark side behind fireflies' summer light shows. While it's energetically cheap for fireflies to produce their distinctive flash signals, flashier males are more likely to end up on the dinner table. The importance of these two conflicting forces could shift in different firefly populations. This evolutionary balancing act might generate entirely new firefly species with distinctive flash codes.
If you want to catch a trophy northern pike, walleye or brook trout in the northern Canadian wilderness, better plan your trip soon.
