Natural disturbances and fish: Local and regional influences on winterkill of fathead minnows, Pimephales promelas, in boreal lakes
Download2003
We investigated the population dynamics of fathead minnow Pimephales promelas and the environmental factors of four small lakes in the boreal forest of Alberta, Canada, for 5 years to determine the influence of local and regional factors on the development of hypoxia and the occurrence of fish...

Abstract: Speciation has been considered as a primary process contributing to species diversity, but its contribution to the diversity of local communities has not been fully appreciated. Based on the theory of classic island biogeography, we derived a model for the number of endemic species as a...

Langor, D. W., Spence, J. R., Pinzon, J.
Abstract: Logging is the main human disturbance in the boreal forest; thus, understanding the effects of harvesting practices on biodiversity is essential for a more sustainable forestry. To assess changes in spider composition because of harvesting, samples were collected from three forest...

Connor, E.F., Srivastava, D., Gaston, K.J., He, F.
While local processes (e.g., competition, predation, and disturbance) presumably cause species exclusion and thus limit diversity in individual communities, regional processes (e.g., historical events, immigration, and speciation) are assumed to provide a source of species to colonize and thus...

Throughout the twentieth century, tuberculosis (TB) was and continues to be a pressing health problem facing Canadians. Aboriginal peoples living in Canada carry a large burden of the disease with those living in the Prairie Provinces facing TB rates consistently higher than the national average....
