How the invasive Prussian carp change Canadian freshwater ecosystems

After the presence of invasive non-native species of Prussian carp was confirmed in Alberta, scientists explored the species’ effect on the local freshwater ecosystems. In the present study, authors describe the carps’ impact on fish communities and benthic invertebrate communities, as well as evaluate whether the carp alter abiotic conditions in the regions where they are abundant. Their findings […]

How risky is ballast water?

Many invasive species – e.g. zebra mussels – hitch a ride across oceans in ships’ ballast water, but a new study shows that some trips may pose more risk than others. Researchers sampled ballast water each day as ships crossed the ocean and discovered that invasive species are more likely to survive a shorter trans-Atlantic […]

Public education and firewood subsities could help stop invasive pests

The spread of the emerald ash borer and the Asian longhorned beetle has been helped thanks to fire. Each species is able to hide among pieces of firewood to travel to new habitats. A new study uses mathematical modelling to show that public education coupled with a subsidy to decrease the cost of local firewood […]

Dogs can sniff out stink bugs in winter before they damage crops

A new study shows that dogs can help us understand ecology of the brown marmorated stink bug. The stink bug is an invasive agricultural pest that was first spotted in Canada in 2012 and has since spread throughout Ontario. Two Labrador retrievers were trained to recognize the smell of the bugs and locate the dead […]
