Canadian Journal of Zoology, Ahead of Print. Microplastics are hazardous to aquatic life. Most experiments focus on the effects of a single type of microbead, while in the environment, organisms are exposed to irregularly shaped fragments belonging to…
Canadian Journal of Zoology, Ahead of Print. Comparative research conducted during the past two decades revealed ecological and evolutionary consequences of interspecies differences in relation to brain size. However, relatively much fewer studies hav…
Canadian Journal of Zoology, Ahead of Print. The threats that affect a species often vary within its geographic range. Wood Turtles (Glyptemys insculpta (Le Conte, 1830), formerly Clemmys insculpta (Le Conte, 1830)) are a species of concern due to wid…

Canadian Journal of Zoology, Ahead of Print. Sexual size dimorphism is a common phenomenon in mammals, and researchers have been trying to demonstrate the evolutionary causes leading to sexual dimorphism. Two main hypotheses emerged: (1) the sexual se…
Canadian Journal of Zoology, Ahead of Print. Many avian species co-roost with other avian species, but roost sharing has not previously been reported for species that roost in enclosed spaces. We report co-roosting of Chimney Swifts (Chaetura pelagica…
Canadian Journal of Zoology, Ahead of Print. In the wild, vertebrates face numerous unpredictable and harmful stressors such as storms, fires, earthquakes, tsunamis, and others. A typical physiological response to a perceived stressor is the increased…
Canadian Journal of Zoology, Ahead of Print. The young-of-year (YOY) habitat of many fishes listed under the Species at Risk Act (SARA) is poorly described, yet identifying critical habitat is essential to ensure species recovery. Past research on the…
