Cranial Morphology, Taxonomy, and Systematics of Pachycephalosaurids (Dinosauria, Ornithischia)
DownloadSpring 2022
Pachycephalosauridae (pachcycephalosaurids) were small to medium sized bipedal ornithischians, known solely from the Late Cretaceous of North America and Asia. These dinosaurs are characterised by thick, often domed frontals and parietals (frontoparietal dome), which are thought to have been used...

Diversity of wetland non-biting midges (Diptera: Chironomidae) and their responses to environmental factors in Alberta
DownloadSpring 2016
Wetlands provide a wide range of services, including improving water quality, providing habitats for wildlife, and storing floodwaters. In Alberta, wetlands cover about 21% of the landscape of the province. In Alberta, as elsewhere, wetlands have suffered from human activities and many have...

Soil Mesostigmata (Arachnida: Parasitiformes) in boreal forests of Alberta: diversity and utility as indicators of disturbance
DownloadSpring 2018
Soils provide numerous ecosystem services, including provision of nutrients for plants, sequestration of greenhouse gases, and serving as habitat for soil animals. Soil animal diversity is immense, and many undescribed taxa still remain. One prominent group that inhabits soils is mites...

Benthic marine habitats in Canada have been well-sampled since the annual groundfish survey commenced in 1970. However, trawl surveys cover only non-rocky sediments and many species collected are not identified to lower taxa, leaving large gaps in our understanding of benthic diversity. Sponges...

Identification of bacterial isolates is important for taxonomic purposes, as well as to predict behaviour and properties of organisms in evolutionary, ecological, industrial, or medical contexts. This process embraces a polyphasic approach (phenotypic, genotypic, and phylogenetic), but has been...
