Welz, M., Faulkner, S.G., Tonn, W.M., Schmitt, D.R.
Industrial development, including geophysical exploration and mining, has increased use of explosives in and near fish habitat. To protect fish and their incubating eggs, Canadian blasting guidelines contain maximum allowable limits for overpressure and peak particle velocity (PPV). Although many...

Effects of exposure to pheromone and insecticide constituents of an attracticide formulation on reproductive behavior of oriental fruit moth (Lepidoptera: Tortricidae)
Download2005
Evenden, M. L., Czokajlo, D., McLaughlin, J. R.
Abstract: The effect of exposure to both the pheromone and insecticide constituents of an attracticide formulation on subsequent pberomonal response of male oriental fruit moth, Grapholita molesta (Busek) (Lepidoptera: Tortricidae), was tested in several wind tunnel bioassays. Male response to...

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...

Effects of Habitat Fragmentation on Pairing Success of Ovenbirds: Importance of Male Age and Floater Behavior
Download2001
Bayne, Erin M., Hobson, Keith A.
Between 1996 and 1998, we compared pairing success of territorial male Ovenbirds (Seiurus aurocapillus) in forest fragments created by forestry (n 5 3) and agriculture (n 5 10) to contiguous forest plots (n 5 3) in the southern boreal mixedwood forest of central Saskatchewan. The percentage of...

McCauley, E., Lewis, Mark A., Lutscher, F.
The question how aquatic populations persist in rivers when individuals are constantly lost due to downstream drift has been termed the “drift paradox.” Recent modeling approaches have revealed diffusion-mediated persistence as a solution. We study logistically growing populations with and...

Effects of seismic lines on the abundance of breeding birds in the Kendall Island Bird Sanctuary, Northwest Territories, Canada
Download2008
Ashenhurst, A.R., Hannon, S.J.
Current plans to increase oil and gas exploration and extraction in the Canadian Arctic include development in the Kendall Island Bird Sanctuary, Northwest Territories. Various studies have shown impacts of seismic lines on vegetation, but the effects on bird abundance in the Arctic are poorly...

Faulkner, S.G., Tonn, W.M., Schmitt, D.R., Welz, M.
Blasting in or near water can negatively affect fish. In Canada, there are maximum allowable limits for blasting-induced overpressure (100 kPa) and peak particle velocity (PPV; 13 mm/s) to protect fish and their incubating eggs, respectively. No studies, however, have related PPVs from blasting...

Effects of solar ultraviolet radiation on stream benthic communities: an intersite comparison
Download2003
Schindler, D. W., Bothwell, M. L., Kelly, D. J.
The effects of solar ultraviolet radiation (UVR), both mid-ultraviolet (UVB; 280-320 nm) and near-ultraviolet (UVA; 320-400 nm), on benthic algal and invertebrate communities were compared in three reaches of a British Columbia coastal stream that differed in the degree of shading by riparian...
