Monodictys arctica, a new hyphomycete from the roots of Saxifraga oppositifolia collected in the Canadian High Arctic
Download2006
Currah, R. S., Fujimura, K. N., Egger, K. N., Day, M. J., Gibas, C. F. C.
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 Aspen
Download2004
Tsuneda, A., Hambleton, S., Currah, R.S.
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...

I argue that in order to resolve the debate between taxonomic monism and taxonomic pluralism, we should construe the reality of natural kinds in terms of relative fundamentality: a natural kind is real if and only if it is more fundamental than its members, whose reality is taken for granted in...

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...

This thesis examines Charles R. Knight’s images of dinosaurs produced around the turn of the nineteenth century in comparison to natural history images of living animals. Using a combination of scholarship from animal studies and an analysis of the side of production, it argues Knight used visual...

Reexamining Sample Size Requirements for Multivariate, Abundance-Based Community Research: When Resources are Limited, the Research Does Not Have to Be

Forcino, F. L., Leighton, L. R., Twerdy, P., Cahill, J. F.
Community ecologists commonly perform multivariate techniques (e.g., ordination, cluster analysis) to assess patterns and gradients of taxonomic variation. A critical requirement for a meaningful statistical analysis is accurate information on the taxa found within an ecological sample. However,...

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...

Many adult concepts can be represented in taxonomies – hierarchical systems in which concepts are differentiated into varying levels of abstraction (e.g., musical instrument, wind instrument, flute) related by class inclusion (a flute is a wind instrument and a wind instrument is a musical...

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...
