A University of Victoria molecular biologist has gained new insights into how environmental contaminants may disrupt thyroid systems. The discovery was made while assembling the genome of the North American bullfrog.

Caren Helbing’s findings could help explain the mechanisms of early development, as well as how environmental contaminants cause thyroidrelated diseases and malfunctions.

Birds exposed to the persistent noise of natural gas compressors show symptoms remarkably similar to those in humans suffering from post-traumatic stress disorder, new research shows.

The world’s reefs are under siege from global warming, according to a novel study published today in the prestigious journal Science.

One morning not long ago, in the southern Indian state of Karnataka, I traveled with a Wildlife Conservation Society biologist on a switchback route up and over the high ridge of the Western Ghats. Our itinerary loosely followed the corridor connecting Bhadra Tiger Reserve with Kudremakh National Park 30 miles to the south.

The combined effects of pesticides and a lack of nutrition form a deadly one-two punch, new research from biologists at the University of California San Diego has shown for the first time.

A University of Victoria molecular biologist has gained new insights into how environmental contaminants may disrupt thyroid systems, discovered while assembling the genome of the North American bullfrog.

Caren Helbing’s findings could help explain the mechanisms of early development and metamorphosis, as well as how environmental contaminants cause thyroid-related diseases and malfunctions.

Aerial drone footage of bowhead whales in Canada’s Arctic has revealed that the large mammals moult and use rocks to rub off dead skin.

The footage provides one answer to the mystery of why whales return to Cumberland Sound, Nunavut, every summer, and helps explain some unusual behaviour that has been noted historically by Inuit and commercial whalers living and working in the area.

Old forests that contain large trees and a diversity of tree sizes and species may offer refuge to some types of birds facing threats in a warming climate, scientists have found.

Amphibians—the big-eyed, swimming-crawling-jumping-climbing group of water and land animals that includes frogs, toads, salamanders and worm-like caecilians—are the world’s most endangered vertebrates. 

One-third of the planet’s amphibian species are threatened with extinction. Now, these vulnerable creatures are facing a new foe: the Batrachochytrium salamandrivorans (Bsal) fungus, which is the source of an emerging amphibian disease that caused the die-off of wild European salamander populations.

A team of researchers from Environment Canada and Climate Change Canada and McMaster University have found that fish living downstream from a wastewater treatment plant showed changes to their normal behaviour—ones that made them vulnerable to predators—when exposed to elevated levels of antidepressant drugs in the water.

The findings, published as a series of three papers in the journal Scientific Reports, point to the ongoing problem of prescription medications, personal care products and other drugs that end up in the watershed and the impact they have on the natural environment.
