Canadian Journal of Zoology, Ahead of Print. Recent studies have highlighted the importance of salmon (genus Oncorhynchus Suckley, 1861) in the diet of bears, and of bears as consumers and key agents supporting the transport of salmon-derived nutrient…
Canadian Journal of Zoology, Ahead of Print. Parasites can influence host population health and dynamics and are often an overlooked aspect of the ecology of ecosystems. Understanding the impacts of ecological interactions between parasites and small …
Canadian Journal of Zoology, Ahead of Print. Swallow (Family: Hirundinidae) populations in the Canadian Maritimes have declined since the 1980s. Using mark–recapture data from 2012 to 2019, we determined apparent annual adult survival rates for Barn (…
Canadian Journal of Zoology, Ahead of Print. The decline of avian aerial insectivores has been greater than any other foraging guild and both climate change and agricultural intensification are leading hypotheses explaining this decline. Spring cold s…
Canadian Journal of Zoology, Ahead of Print. Cestodes of the genus Triaenophorus Rudolphi, 1793 are widely distributed parasites of Esocidae, Percidae, Salmonidae, Thimallidae, Cobitidae, Osmeridae, Cyprinidae, Cottiidae, Lotidae, and several others i…
Canadian Journal of Zoology, Ahead of Print. Anti-predator behavior is often evoked based on measurements of risk calculated from sensory cues emanating from predators independent of physical attack. Yet, the exact sensory indices of cues used in risk…
Canadian Journal of Zoology, Ahead of Print. Accurate and precise estimates of the timing of whisker growth and shedding are necessary to interpret biochemical information stored in whiskers. This fine-scale examination of harbor seal (Phoca vitulina …
Canadian Journal of Zoology, Ahead of Print. Winter is a costly time for animals, requiring individuals to adapt to increased energetic costs and reduced resources. Porcupines (Erethizon dorsatum (Linnaeus, 1758)) confront winter by storing and catabo…
Canadian Journal of Zoology, Ahead of Print. Trophy hunting can affect weapon size of wild animals through both demographic and evolutionary changes. In bighorn sheep (Ovis canadensis Shaw, 1804), intense harvest of young males with fast-growing horns…
Canadian Journal of Zoology, Ahead of Print. The reproductive period is a critical part of a species’ life history. Estimating species-specific fecundity can improve demographic models aimed at developing recovery targets for imperilled species. We pr…
