Leach’s storm-petrels (Oceanodroma leucorhoa) are long-lived seabirds that spend most of the year on the open ocean and return from overwinter grounds in the southern hemisphere to breed in large colonies in Atlantic Canada. Since the 1990s, breeding colonies have severely declined and Leach’s storm-petrels are listed as Threatened in the COSEWIC registry of species […]

In the Arctic, climate change is leading to declines in seasonal sea-ice cover. Polar bears are increasingly at-risk from sea-ice loss because they use the ice as a platform to hunt seals, their preferred food source. When the ice retreats seasonally, bears rely on their stored energy reserves as fuel, but climate-driven changes in sea-ice […]

La contamination des sols est une problématique qui touche la majorité des municipalités canadiennes. Plusieurs facteurs font en sorte que ces terrains peuvent rester vacants pendant plusieurs années avant qu’on ne leur trouve une seconde vocation. En plus des risques toxicologiques qui leur sont associés, certains sites sont pauvrement végétalisés et exacerbent les effets d’îlots […]

This project critically assesses the work of K-12 educators has been affected by the policies of the Ontario government under Premier Ford, both prior to the COVID-19 pandemic, including class size increases and mandatory e-learning, as well as during the pandemic, including its public health policies, the pivot to virtual learning and alternative school timetables.

Social reproductive suppression is when the reproduction of healthy, adult animals in a population is inhibited by the presence of a socially dominant individual. This is known to happen some group-living species, where only the dominant pair will reproduce, and the other group members will assist in raising their young. There is evidence that social […]

Un marché public est dit « durable » lorsqu’il arrive à concilier les trois piliers du développement durable (économique, environnemental et social). Au Canada, rien n’oblige les acheteurs publics à imposer des spécifications techniques ou des critères de développement durable (critères environnementaux ou sociaux) dans les appels d’offres. Pourtant, de nombreuses entités dans le monde […]

The holobiont view of organism microbiomes suggests that microbial communities influence and are influenced by animal behaviour. While many microbes are beneficial and necessary for digestion and homeostasis, others can be detrimental, including pathogens leading to compromised immunity and disease states. Recent studies suggest microbiomes covary with landscape floral and fungal diversity, yet fine scale […]
