Abstract: During a survey of microfungi from rotting wood in northern Alberta forests, 49 species of ascomycetes, representing 24 genera, and 15 families in seven orders, were recovered. Twenty-eight species are new reports for Alberta, 15 of which are new for Canada, and seven are new for North...

Microstructural Changes in Noncoding Chloroplast DNA: Interpretation, Evolution, and Utility of Indels and Inversions in Basal Angiosperm Phylogenetic Inference
Download2000
Olmstead, R.G., Burns, A.C.E., Graham, S.W., Reeves, P.A.
Microstructural changes in several very slowly evolving chloroplast introns and intergenic spacers were characterized across a broad range of angiosperms, including most of the major basal lineages. Insertion/ deletion events (indels) in the surveyed noncoding regions of the large inverted repeat...

Migration and survival of Parnassius smintheus: Detecting effects of habitat for individual butterflies
Download2004
Hanski, I., Roland, J., Matter, S. F., Moilanen, A.
We examined the migration and survival of the butterfly Parnassius smintheus in a heterogeneous landscape consisting of 21 habitat patches imbedded in a matrix of meadow and forest habitat. We modified an existing mark-release-recapture model to account for multiple habitat types and fit the...

Migratory host vectors can maintain the high-dose refuge effect in a structured host-parasite system: the case of sea lice and salmon Evolutionary Applications

Migration can reduce parasite burdens in migratory hosts, but it connects populations and can drive disease dynamics in domestic species. Farmed salmon are infested by sea louse parasites, often carried by migratory wild salmonids, resulting in a costly problem for industry and risk to wild...

Minimizing invasion risk by reducing propagule pressure: a model for ballast-water exchange
Download2005-01-01
Lewis, Mark A., Wonham, Marjorie J., MacIsaac, Hugh J.
Biological invasions are a major and increasing agent of global biodiversity change. Theory and practice indicate that invasion risk can be diminished by reducing propagule pressure, or the quantity, quality, and frequency of introduced individuals. For aquatic invasions, the primary global...

We present a literature survey and analysis of the profile of mites (Acari, exclusive of Ixodida) in recent literature and on the World Wide Web, and compare their prominence to that of spiders (Araneae). Despite having approximately the same number of described species, spiders outshine mites on...

Mitochondrial DNA variation and identification of bark weevils in the Pissodes strobi species group in western Canada (Coleoptera: Curculionidae)
Download1995
Sperling, F. A. H., Langor, D. W.
Abstract: Morphological, allozyme, and chromosomal characters and ecological traits have limited value for discriminating among four closely related Pissodes spp. known from western Canada. We amplified a 1585-bp segment of mitochondrial DNA (mtDNA), including half of the cytochrome oxidase I...
