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...

Effects of Source of Metacercariae on Experimental Infection of Zygocotyle lunata (Digenea: Paramphistomidae) in CD-1 Mice.
Download1993
Shostak, A.W., Belosevic, M., Dharampaul, S.
Outbred (CD-1 strain) mice were infected experimentally with metacercariae of Zygocotyle lunata obtained from naturally infected Helisoma trivolvis. Growth, survival, and fecundity of the parasite and gross pathology in the host were evaluated. Metacercariae from 5 snail sources produced 3...

Gurevitch, J., Fortin, M. J., Legendre, P., Casgrain, P., Dale, M. R. T.
Abstract: Field experiments have been designed to account for spatial Structures since the inception of randomized complete block designs by R. A. Fisher. In recent years, our understanding of spatial structures led to refinements in the design and analysis of field experiments in the face of...

Empirical estimation of R0 for unknown transmission functions: The case of chronic wasting disease in Alberta
Download2015-01-01
Potapov, Alex, Merrill, Evelyn, Pybus, Margo, Lewis, Mark A.
We consider the problem of estimating the basic reproduction number R0 from data on prevalence dynamics at the beginning of a disease outbreak. We derive discrete and continuous time models, some coefficients of which are to be fitted from data. We show that prevalence of the disease is...
