Lake Trout adjust their behaviour in the face of a changing climate
September 7, 2017 08:02 AM - Lakehead University

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.

Research Dog Helps Scientists Save Endangered Carnivores

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.

A race against time: Saving the North Atlantic right whale
September 5, 2017 09:01 AM - Dalhousie University

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.

Antarctic marine life may grow faster in a warming world
August 31, 2017 02:24 PM - British Antarctic Survey

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).
