An invasive species of crayfish that reproduces by cloning itself was discovered last summer in a Burlington, Ont., park — the first time the marbled crayfish has been identified in the wild in North America. Since then, a group of experts has been working to stop the species from spreading. The crayfish are in City View park, on … Read more
In an effort to reduce the spread of marine invasive species, Canada ordered lobster pounds to euthanize all egg-bearing female lobsters. But two years after the measure was introduced, some in the business are still unaware of the requirement. The Department of Fisheries and Oceans has banned the long-held practice of releasing egg-bearing or “berried” … Read more
WASHINGOTN: An ancient species of great ape was likely driven to extinction hundreds of thousands of years ago when climate change put their favorite fruits out of reach during dry seasons, scientists reported Wednesday. The species Gigantopithecus blacki, which once lived in southern China, represents the largest great ape known to scientists – standing 10 … Read more
The 2013 discovery of the largest collection of hominid fossils ever found is rewriting the origin of complex behaviours we thought were uniquely human, says a renowned paleoanthropologist. The fossilized bones belonged to an entirely new species of ancient human relatives called, Homo naledi, which lived in South Africa several hundred thousand years ago when the first Homo … Read more
Not far from the bank of Wapiti River, just 11 kilometres from Grande Prairie, there’s a paleontological goldmine: an ancient riverbed that contains fragments of skeletons of hundreds, possibly thousands, of animals from the late Cretaceous period, some 70 million years ago.

In a converted shipping container perched oceanside in Ketch Harbour, N.S., a group of people gather to peer into tanks filled with fuzzy pieces of gravel. The rocks are covered with tiny blades of sugar kelp. Soon, the squares of steel mesh they’re fixed to will be suspended in the water at a kelp farming demonstration … Read more

Warming ocean temperatures caused by climate change will provide favourable conditions for Atlantic halibut, according to a new study, although what happens to their prey is uncertain. A paper published in the journal FACETS links an exponential increase in Atlantic Canadian landings over the past decade to warming ocean temperatures and predicts that trend is … Read more
