Parasites may be taking heavy toll on mammal populations

May not kill, but have heavy effect on mammals overall health

Parasites may be taking heavy toll on mammal populationsA new study looking at research on parasitic worms suggests the pesky, but pervasive creatures have a far greater impact on the health of mammal populations than previously known. “Parasites don't have to kill the animal to control a population,” says Kyle Shanebeck, a PhD student in the Faculty of Science’s Department of Biological Sciences…

There’s room for everyone in nature – if we’re respectful

The only time we need to stand up is when nature is negatively impacted by someone’s actions

I’m a dedicated birdwatcher, as I think you might have figured out by now. Years ago, I went to Rondeau Provincial Park in Ontario to look for a very rare bird – a sage thrasher…

Researchers create new method for making lifelike aquatic artificial habitats

Studying living habitats that attract and retain different organisms is crucial in restoration planning

Researchers create new method for making lifelike aquatic artificial habitatsResearchers have devised a new method of making lifelike aquatic artificial habitats that could help scientists better understand and restore real-world environments. Aneri Garg, who completed the research as part of her master’s studies under the supervision of Stephanie Green, first developed the 3D scanning, printing, moulding and casting (3D-SPMC) method on a project involving coral reefs. As…

We forget…

New strains of wheat sought with built-in resistance to wheat midge

There’s currently only one genetic defence to protect from wheat midge – but researchers want to change that

New strains of wheat sought with built-in resistance to wheat midge Agricultural scientists in Western Canada are teaming up to give wheat a boost of built-in resistance to a destructive pest. “Wheat midge is the number one insect pest threatening wheat crops across Western Canada,” says James Harynuk, a professor in the University of Alberta’s Faculty of Science. Harynuk notes that wheat midge can cause about $60…
