As the climate changes, researchers often focus on how temperature may affect a species’ ability to survive. But survival isn’t the only concern. Changing temperatures could affect species’ ability to reproduce, and that could lead …
When North Atlantic right whales get entangled in fishing gear, it can have long-term consequences for their populations. Not only can the energy cost of carrying the gear around cause the whales to become smaller, …
Early estimates from Wyoming’s 2021 sage-grouse wings indicate reproduction declined slightly in the last year. Wings from harvested chick and hen sage-grouse are collected from hunters who voluntarily drop them off at designated collection points. …
When North Carolina State University researchers set out to collar black bears in the city of Asheville, they noticed something unusual. Yearlings are often too small to support the weight of the GPS collars, but …
In bear country, it’s not uncommon to notice the evidence of a bear rubbing against a tree, even if you don’t catch it in the act. Claw marks may be etched in the bark. Hair …
Lots of studies look at how climate change may impact a certain aspect of a mammal’s lifecycle, but a team of researchers say we need to start looking at the bigger picture. They’re calling for …
People who live off the land, such as hunter-gatherers or foraging humans, tend to behave similarly to their wildlife counterparts when it comes to foraging, reproduction and even social interaction, researchers found. Given that human …
Researchers have long thought that migrating species pay a cost for the energy they spend making long journeys. But what exactly is the tradeoff for these journeys? And what role could climate change play as …
Noise and light pollution have been known to cause behavioral changes in birds, but researchers recently found they can actually affect their reproductive fitness. “We know that sensory pollutants are affecting wildlife in many ways, …
Birds that thrive in urban environments either have larger brains or the ability to reproduce multiple times throughout their lifespan, researchers found. Past research showed that birds with larger brains had higher intelligence in cities …
