City life is tough for young birds. But if they survive their first year, they are less susceptible to the effects of stress, according to research from Lund University in Sweden.

An examination of long-term data for lands managed by the Bureau of Land Management finds that land treatments in the southwestern United States are increasingly large, expensive and related to fire and invasive species control.

The study, recently published in Restoration Ecology, reveals an extensive legacy of land management decisions and provides new insight on strategies to increase future treatment efficacy in an extremely water-limited region.

Canadian scientists have discovered that certain lake predators are altering their behaviour due to climate change, revealing what the future may hold for these fish and their food.

For years scientists told tales of fish such as Lake Trout adapting their feeding behaviour as temperatures change, but no empirical evidence existed. Now, a recently completed 11-year study at IISD Experimental Lakes Area (IISD-ELA) in northwestern Ontario reveals that Lake Trout have a remarkable ability to adjust their behaviour in the face of changing water temperatures.

Scat-sniffing research dogs are helping scientists map out a plan to save reclusive jaguars, pumas, bush dogs and other endangered carnivores in the increasingly fragmented forests of northeastern Argentina, according to a new study from Washington University in St. Louis.

In June 2017, three critically endangered North Atlantic right whale carcasses were spotted floating in the Gulf of St. Lawrence. In the weeks that followed the number of dead right whales rose to 10, while three more were found entangled alive in fishing gear. (The total number of deaths may be as high as 12.)

For a species with approximately 500 surviving animals in the world, this was a crisis — an unprecedented die-off signalling a troubled outlook for the species.

Study documents local extinction of pikas from the largest area yet reported and projects climate change will cause drastic decline for the charismatic mammal within decades.

Human antidepressants are building up in the brains of bass, walleye and several other fish common to the Great Lakes region, scientists say.

A team of scientists has discovered that a 1°C rise in local sea temperature has massive impacts on an Antarctic marine community. These new results are published this week (31 August) in the journal Current Biology, and enable researchers to better understand the biological implications of the future ocean warming predicted by the Intergovernmental Panel on Climate Change (IPCC).

Pines in Canada and Much of U.S. at Risk.

Scientists used historical data and models to predict the impacts of six planned or potential Andean dams on the Amazon river system.
