What's in your herbal remedy? Using DNA barcoding and DNA-based biological reference material library to test herbal products

Previous studies led by Prof. Newmaster and colleagues in 2013 have estimated high levels of adulteration in North American herbal products resulting in investigations into some of the largest herbal supplements manufacturers in the nation. His lab continues to be a leading expert in this area of research and his students are highly sought after for their expertise in this field.

Wildflowers can limit the amount of pollen deposited on each bee visitor

Many plant species depend on animals such as bees to transfer pollen from flower to flower.  This dependence on bees is risky because they can consume pollen rather than transferring it to another flower.  Plants can reduce this risk by limiting the amount of pollen deposited on each successive bee visitor.

Give males some credit too – how older male gray jays influence female nesting behaviour

Dr. Ryan Norris and his colleagues provide first evidence of the importance of male experience on the timing of breeding in female birds.

Female gray jays (Perisoreus Canadensis) can adjust their reproductive timing in response to variation in the environment through phenotypic plasticity (the ability of an individual to adjust behaviour in response to different environmental conditions).

Academia, government and industry partners work together to solve a decades old question about fish recruitment

Since the early twentieth century, multiple theories have been developed to explain variation in fish recruitment asserting alternative views regarding the importance of various biological and physical factors.

However, none of the recruitment hypotheses universally explains fish recruitment dynamics, and understanding the drivers of fish recruitment remains a major challenge in fisheries science today.

Time-calibrated phylogeny for seed plant species

Prof. Hafiz Maherali and collaborators help to explain the persistence of symbiosis between plants and mycorrhizal fungi

The prevalence of mutualism nature, in which different species cooperate for common benefit, is difficult to explain. Theory conflicts on whether mutualisms should be stable or abandoned over evolutionary time. On the one hand, natural selection is expected to favour exploitation over cooperation because individuals that derive benefit from a mutualistic partner can maximize their own fitness by cheating, or otherwise avoiding the costs of cooperation.
