Canadian Journal of Zoology, Ahead of Print. Increased human presence in the Arctic may affect its vulnerable ecosystems. Effects on arctic and red foxes provide notable examples. Both have been documented to take anthropogenic subsidies when availabl…
Canadian Journal of Zoology, Ahead of Print. The drivers of year-to-year difference in winter abundance patterns, particularly dramatic in the “eruptions” of many boreal seed-eating birds, are poorly understood. Varied Thrush (Ixoreus naevius (Gmelin,…
Canadian Journal of Zoology, Ahead of Print. Fear level and intraguild predation are factors that act together to directly influence animal behavior, population dynamics, and community structure. These factors trigger stress, which promotes behavioral…
Canadian Journal of Zoology, Ahead of Print. Chinook salmon (Oncorhynchus tshawytscha (Walbaum, 1792)) from the upper Yukon River are highly unique, with some populations migrating nearly 3000 km to spawning habitat near the northern range limit for t…
Canadian Journal of Zoology, Ahead of Print. Predators influence microhabitat selection and activity level of tadpoles, but it is still unclear how such responses to predators differ among species and how water column’s depth influences this predator–…
Canadian Journal of Zoology, Ahead of Print. Invasive conservation actions that require the capture and handling of individual animals are common, but the implications for both survival and reproduction are often not studied. Across North America, mos…
Canadian Journal of Zoology, Ahead of Print. The lateral plates of threespine stickleback (Gasterosteus aculeatus Linnaeus, 1758) are well studied for their adaptive morphological responses to predators, yet it is unknown whether habitat influences pl…
Canadian Journal of Zoology, Ahead of Print. Hermaphroditism has been widely reported in the Crustacea, but protogyny, in which females change to males, is apparently rare and restricted to the peracarid orders Isopoda and Tanaidacea. In the latter, p…
Canadian Journal of Zoology, Volume 100, Issue 7, Page 474-479, July 2022. The winter tick (Dermacentor albipictus (Packard, 1869); Acari: Ixodidae) significantly affects the health and productivity of North American moose (Alces alces (Linnaeus, 1758…
Canadian Journal of Zoology, Volume 100, Issue 7, Page 452-463, July 2022. Anurans are generalist opportunistic consumers, but many species show some degree of diet specialization. Within populations, individuals may specialize in specific dietary res…
