New University of Alberta research on managing aquatic invasive species in Canada combines the power of machine learning with expertise in biology and statistics to build a simple, easy-to-use tool for environmental managers.

Conservationists often criticize state fish and game departments for focusing single-mindedly on one species to the detriment of everything else — for instance, improving habitat for elk, which then browse down habitat for songbirds. But what if conservationists — who don’t have that traditional hook-and-bullet mindset — nonetheless inadvertently do much the same thing?

For decades, researchers have thought that access to food determined the brood size of birds. Now, biologists at Lund University in Sweden have discovered a completely new explanation: the body temperature of small birds can increase by more than 4°C to exceed 45°C when they are feeding their young. Larger broods would require more work, resulting in even higher body temperatures - something the birds would probably not survive.

With the arrival of spring, we look forward to the return of hundreds of species of migratory songbirds from their wintering grounds.

Two species of seal found in Antarctic seas are helping scientists collect data about the temperature and salinity of waters around vulnerable ice sheets in West Antarctica.

Orangutans, already critically endangered due to habitat loss from logging and large-scale farming, may face another threat in the form of smoke from natural and human-caused fires, a Rutgers University–New Brunswick study finds.

In the Arctic, marine mammals such as belugas and bowhead whales rely on a quiet environment to communicate and forage. But as Arctic sea ice shrinks and shipping traffic increases, vessel disturbance could very likely impact their social behaviours, distribution and long-term survival, warns a new study led by University of Victoria marine biologist Lauren McWhinnie.

Sandie Black first saw giant pandas at the Calgary Zoo in 1988 when she applied for a job with the veterinary staff. Fast-forward 30 years, Black is now tasked with caring for a family of the iconic black and white bears who will call the Calgary Zoo home for the next five years.

Jackdaws recognise each other’s voices and respond in greater numbers to warnings from familiar birds than strangers, new research shows.

Swarms of tiny oceanic organisms known collectively as zooplankton may have an outsize influence on their environment. New research at Stanford shows that clusters of centimeter-long individuals, each beating tiny feathered legs, can, in aggregate, create powerful currents that may mix water over hundreds of meters in depth.
