How animals use mimicry to survive and thrive

Mimicry is usually designed to protect prey from predators. But some also use the tactic to fool prey

How animals use mimicry to survive and thriveWhat you see may not be what you get when it comes to the natural world. Many animals use mimicry to fool predators and prey into thinking they’re something else, with insects putting on the best show in this regard.

But a specimen formerly thought to fit the bill is not the missing piece of the puzzle, according to a new study led by…

Raptors on the move are a sight to behold

Food and weather are driving migration forces. The best places to look are along coastal areas

Raptors on the move are a sight to beholdNo, this article on raptors isn’t about basketball – it’s about birds.

Exploring bee behaviour opens new career possibilities

Tianna Tanasichuk's internship was a chance to gain experience – not learn about herself

Exploring bee behaviour opens new career possibilitiesWorking in the sunshine, surrounded by the soft hum of a dozen beehives this summer, Tianna Tanasichuk couldn’t help thinking of her recently passed Métis great-grandmother. “Whenever I was working with the bees, I felt like if she was here, she’d be proud of me, knowing I took this risk, of trying to grow by…

Predicting which species most at risk from voracious lionfish predators

We have only two to five years to act once lionfish arrive

Predicting which species most at risk from voracious lionfish predatorsCoastal countries have between two and five years to act to protect native fish species once voracious lionfish arrive in their waters, according to a University of Alberta ecology professor who helped create a tool to predict which fish are in danger. The lionfish, originally a popular aquarium species native only to the Pacific and…
