Landscape patterns of species-level association between ground-beetles and overstory trees in boreal forests of western Canada (Coleoptera, Carabidae)
Download2011
Spence, J. R., Volney, W. J. A., Bergeron, J. A. C.
Abstract: Spatial associations between species of trees and ground-beetles (Coleoptera: Carabidae) involve many indirect ecological processes, likely reflecting the function of numerous forest ecosystem components. Describing and quantifying these associations at the landscape scale is basic to...

Low intensity surface fire instigates movement by adults of Calosoma frigidum (Coleoptera, Carabidae)
Download2011
Jacobs, J. M, Work, T. T., Spence, J. R., Bergeron, J. A. C.
Abstract: The genus Calosoma (Coleoptera: Carabidae) is a group of large, sometimes ornate beetles, which often voraciously attack caterpillars. Many studies have reported Calosoma beetles being highly conspicuous during defoliator outbreaks. Based on observations of individual beetle behavior,...

Macdonald, S. E., Schmiegelow, F. K. A., Shepherd, L.
Abstract: Woodland caribou (Rangifer tarandus caribou) populations in Jasper (JNP) and Banff National Parks (BNP) have declined since the 1970s, coincident with reduced fire activity in both parks, relative to historic levels. Some researchers have suggested that long periods without fire may...

Mandibles and labrum-epipharynx of tiger beetles: Basic structure and evolution (Coleoptera, Carabidae, Cicindelitae)
Download2011
Acorn, J. H., Ball, G. E., Shpeley, D.
Abstract: Using for comparison with, and as outgroups for, supertribe Cicindelitae, we describe and illustrate the mandibles and labrum-epipharynx of the basal geadephagans Trachypachus gibbsii LeConte, 1861 (family Trachypachidae), and family Carabidae: Pelophila rudis (LeConte, 1863)...

Langor, D. W., Cobb, T.P., Spence, J.R., Jacobs, J. M., Hammond, H.E.J.
Saproxylic insect assemblages inhabiting dead wood in Canadian forests are highly diverse and variable but quite poorly understood. Adequate assessment of these assemblages poses significant challenges with respect to sampling, taxonomy, and analysis. Their assessment is nonetheless critical to...

Wing-dimorphism and population expansion of Pterostichus melanarius (Illiger, 1798) at small and large scales in central Alberta, Canada (Coleoptera, Carabidae, Pterostichini)
Download2011
Hartley, D. J., Lee, S.-I., Bourassa, S., Spence, J. R.
Abstract: A study spanning ten years revealed changes in wing-morph ratios corroborating the hypothesis that the wing-dimorphic introduced carabid, Pterostichus melanarius Ill., is spreading through flight, from the city of Edmonton, Canada and establishing populations in natural aspen forest of...
