Canadian Journal of Zoology, Ahead of Print. Squid Lolliguncula panamensis Berry, 1911 is of commercial and ecological importance in the Gulf of Tehuantepec (southeastern Mexico). This study examines the mode of oocyte development, packing in the ovar…
Canadian Journal of Zoology, Ahead of Print. Mass mortality events appear to be increasing in intensity and frequency, so understanding their causes and consequences is imperative for wildlife conservation. We report on a mass mortality event in a pop…
Canadian Journal of Zoology, Ahead of Print. Metabolic rate is a key parameter in fish energy budgets that strongly influences the output of bioenergetics models. In this study, we tested the hypothesis that metabolic rate varies with growth history o…
Canadian Journal of Zoology, Ahead of Print. As temperatures warm in response to anthropogenic changes (climate change and urbanization), animals must respond adaptively to these changes or be displaced. Here, we use community science data (iNaturalis…
Canadian Journal of Zoology, Ahead of Print. Stopovers are the most energy- and time-consuming events during avian migration, yet individuals of certain species make long stopovers to moult (“moult migration”). Requiring abundant energy and a prolonge…
Canadian Journal of Zoology, Ahead of Print. Density estimation is a key goal in ecology, but accurate estimates for unmarked animals remain elusive. Camera trap data can bridge this gap, but accuracy, precision, and concordance varies among estimator…
Canadian Journal of Zoology, Ahead of Print. Many species of anurans display special mechanical abilities, such as excavation and climbing. The aim of this study is to investigate the development of traits that are associated with these special mechan…
Canadian Journal of Zoology, Ahead of Print. Nematode communities in natural pristine forests composed of trees aged over 1000 years have not been thoroughly studied. Old-growth forests can provide diverse microhabitats for nematodes such as fallen tr…
Canadian Journal of Zoology, Ahead of Print. Atlantic cod (Gadus morhua Linnaeus, 1758) can experience mortality at sub-zero (<0 °C) temperatures in ice-infested waters, and many populations migrate to deeper and warmer areas during winter. An exce…
Canadian Journal of Zoology, Ahead of Print. Introgressive hybridization between members of Odocoileus was examined using the mitochondrial cytochrome-b (maternal marker) and paternal sex-determining region Y (Sry) genes. Eight out of 130 free-ranging…
