Distribution of entocytheridae (Crustacea: Ostracoda) in the northern prairies of north america and reports of opportunistic clitellate annelids on crayfish hosts.
Download2011
Williams, B. W., Williams, K. L., Gelder, S. R., Proctor, H. C.
ABSTRACT.—Northern crayfish, Orconectes virilis (Hagen, 1870), were collected from 89 sites across Alberta, Saskatchewan, Manitoba, Montana, North Dakota, and Minnesota. The entocytherid ostracod Thermastrocythere riojai (Hoff, 1943) was found on O. virilis at 45 of the 89 sites, distributed...

Effects of aspen harvesting on groundwater recharge and water table dynamics in a subhumid climate
Download2011
Devito, K.J., Mendoza, C.A., Smerdon, B.D., Carrera-Hernández, J. J., Petrone, R.M.
Numerical experiments were developed using different water table depths and soil textures to investigate the impact of aspen harvesting on hydrological processes on the Western Boreal Plain. The effect of harvesting on soil moisture dynamics, fluxes at the water table, and water table fluctuation...

Effects of forest harvesting and fire on fish assemblages in Boreal Plains lakes: A reference condition approach
Download2003
Scrimgeour, G.J., Lange, M., Prepas, E.E., Westcott, K., Aku, P.K.M., Paszkowski, C.A., Tonn, W.M.
To assess the impacts of forest harvesting and fires on lentic fish assemblages in the Boreal Plains ecoregion (Alberta, Canada), we applied a reference condition approach to 37 lakes in burned, logged, or undisturbed catchments. Fish assemblages in the reference lakes were classified into two...

McLachlan, J. S., Lewis, M. A., HilleRisLambers, J., Clark, J. S.
Recent literature on plant population spread advocates quantification of long-distance dispersal (LDD). These estimates could provide insights into rates of migration in response to climate change and rates of alien invasions. LDD information is not available for parameterization of current...

Small-scale vertical aerial photographs taken in 1947 and 1948 covering 200 km2 of the Kluane Ranges, southwest Yukon, were compared with corresponding photographs taken in 1989 for the purpose of characterizing changes in the distribution and abundance of white spruce (Picea glauca (Moench)...

Vegetative and fertile frond segments of Botrychium have been recovered from Paleocene deposits of central Alberta, Canada. Specimens are preserved as coalified compressions that yield information about frond structure, sporangia, and spore ultrastructure. These fossils, described as Botrychium...

Ciarniello, L. M., Heard, D. C., Boyce, M. S., Seip, D. R.
The purpose of our study is to show how ecologists' interpretation of habitat selection by grizzly bears (Ursus arctos) is altered by the scale of observation and also how management questions would be best addressed using predetermined scales of analysis. Using resource selection functions (RSF)...

Wynes, B. B., Wasel, S. S., Schneider, R. R., Dzus, E. E., Hiltz, M. M.
Habitat mapping and habitat supply assessment have been identified as key elements of the Alberta Woodland Caribou Conservation Strategy. Previous studies from northeastern Alberta have shown that caribou select lowland habitat types and avoid upland. The objectives of our study were to determine...

Fossil seedlings and seeds of an extinct Cercidiphyllum-like plant occur in the Paskapoo Formation (Late Paleocene) at Joffre Bridge near Red Deer, Alberta. Cotyledon and early seedling leaf stages are preserved in growth position. Morphological details of seedlings and seeds support a close...

Influence of subhumid climate and water table depth on groundwater recharge in shallow outwash aquifers
Download2008
Smerdon, B.D., Mendoza, C.A., Devito, K.J.
[1] Hypothetical one-dimensional models of unsaturated flow were used to estimate the probability of groundwater recharge to shallow, glacial outwash aquifers. Simulations were supported by field data, previous three-dimensional modeling, and cross-sectional models of water table response to...
