Fall 2021
The field of animal personality, the study of adaptive among-individual behavioural differences in animal populations, has both exploded in popularity in the last few decades and come under heavy scrutiny by behavioural ecologists. The sudden interest in the field stems from the widespread...

Description of new species of Osteostraci from the Man On The Hill locality, Northwest Territories, Canada, with consideration of the phylogenetic and biogeographic significance of the new taxa
DownloadFall 2011
The Lochkovian (Lower Devonian) Man on the Hill (MOTH ) locality, Northwest Territories, Canada, is a Konservat-Lagerstätte, where articulated early vertebrate remains are found. Among the early vertebrates preserved at the MOTH locality are the Osteostraci. Many specimens of osteostracan have...

Does fluctuating selection maintain variation in nest defense behavior in Arctic peregrine falcons (Falco peregrinus tundrius)?
DownloadFall 2021
Within populations, individuals often exhibit repeatable among-individual differences in behavior, and in some cases, these are linked to different fitness outcomes. Several mechanisms have been proposed to contribute to the maintenance of repeatable among-individual variation in behavior. Here...

Early late Paleocene mammals from the Roche Percée local fauna, southeastern Saskatchewan, Canada
DownloadFall 2009
The occurrence of vertebrate fossils from the Ravenscrag Formation near Roche Percée, southeastern Saskatchewan, Canada, documents the presence of a large and diverse assemblage of early late Paleocene (approximately 58 million years) mammals. Previous studies of the Roche Percée localities have...

Genetic structure of a large recolonizing carnivore: the case of the northern cougars (Puma concolor)
DownloadFall 2023
Anthropogenic activities have pressured and altered landscapes resulting in extinctions and extirpations. However, increased conservation efforts and changing management strategies in some large carnivores have resulted in population and range expansion. Population growth and range expansion are...

Investigating the genetic basis of boldness and reproductive performance traits in the grey seal (Halichoerus grypus)
DownloadSpring 2022
Individual variation provides the material for natural selection to act upon, influencing ecological and evolutionary processes. Much phenotypic variation in traits, such as behaviour and life-history, have a moderate to high heritable component, suggesting that these traits may have adaptive...

Occupancy, Abundance, and Summer Ecology of the Western Tiger Salamander (Ambystoma mavortium Baird) in the Beaver Hills, Alberta
DownloadSpring 2016
The western tiger salamander (Ambystoma mavortium Baird) is a ‘species of special concern’ in the Canadian prairie provinces. Potential declines caused by habitat loss and fragmentation, emergent diseases, and fish stocking are reasons cited for this species conservation status. However, little...

Resources and Reproductive Trade-offs Affect Fitness, Life History Traits, and Sexual Selection in Red Squirrels
DownloadSpring 2017
Animals face trade-offs throughout life between competing functions, such as between self-maintenance, reproduction, and survival. Resource allocation between these competing functions leads to different patterns of life history traits, changes in investment in reproductive effort, and different...

Survey, host preference and infectivity of Phasmarhabditis californica (Family: Rhabditidae) on pest slugs
DownloadFall 2023
Patuwatha Withanage, Dayani B. M.
Certain slug species are considered agricultural and horticultural pests worldwide. Nematodes offer a potential solution as biocontrol agents in controlling slug populations due to their natural associations with terrestrial gastropods. In some cases, they provide higher specificity and more...

Systematics and palaeobiology of the crested hadrosaurine Saurolophus from Canada and Mongolia
DownloadFall 2011
Reappraisal of Saurolophus confirms Saurolophus osborni and Saurolophus angustirostris as distinct species. Synapomorphies of Saurolophus include a spike-like pseudonarial crest formed by the nasals, frontals, and prefrontals; tripartite frontals with anteroventral and posterodorsal extensions...
