Mosasauridae is a lineage of extinct marine squamates that inhabited the world’s oceans during the Late Cretaceous (100-66 Ma). The name Mosasaurus was given to the first described specimen, which was a fossil discovered in Maastricht, the Netherlands, during the 1770s. Naturalists of the time...
Paleontology is a multi-faceted subject that involves taxonomy and community analysis as two of its cornerstones. Both qualitative and quantitative approaches have been incorporated into the various methods employed in such analyses. Each paleontologist obvious has his or her own preference that...
Diversity of wetland non-biting midges (Diptera: Chironomidae) and their responses to environmental factors in AlbertaDownload
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...
Abstract: Epulorhiza inquilina sp. nov. is described from the mycorrhizas of mature plants of Platanthera clavellata, P. cristata and P. integrilabia, coexisting terrestrial orchids native to bogs in the southern Appalachians. The new taxon was isolated consistently and exclusively from these...
The goal of this guide is to derive a better understanding of the biodiversity of sponges across the eastern Canadian Arctic. Specimens were collected during research cruises aboard the Canadian Coast Guard Ship (CCGS) Amundsen in October 2015, July 2016 and July 2017. Collection sites were...
Taxa and homologues can in our view be construed both as kinds and as individuals. However, the conceptualization of taxa as natural kinds in the sense of homeostatic property cluster kinds has been criticized by some systematists, as it seems that even such kinds cannot evolve due to their being...
Monodictys arctica, a new hyphomycete from the roots of Saxifraga oppositifolia collected in the Canadian High ArcticDownload
Abstract: Monodictys arctica sp. nov. is described on the basis of nine isolates obtained from the roots of eight separate collections of Saxifraga oppositifolia from Ellesmere Island, Nunavut, Canada. Conidia are multicelled, smooth, darkly pigmented, and globose, oblong, ellipsoidal, or...
Morphology and Phylogenetic Placement of Endoconidioma, a New Endoconidial Genus from Trembling AspenDownload
Endoconidioma populi gen. et sp. nov. is described from black subicula on twigs of trembling aspen, Populus tremuloides, in Alberta, Canada. Pycnidium- like conidiomata are produced on twigs and in culture, but, unlike pycnidia, conidiomata of E. populi have a closed peridium and a locule filled...
The aim of this article is to illustrate how a belief in the existence of kinds may be justified for the particular case of natural kinds: particularly noteworthy in this respect is the weight borne by scientific natural kinds (e.g., physical, chemical, and biological kinds) in (i) inductive...
