Keyghobadi, N., Roland, J., Fownes, S.

We used mark-recapture methods to estimate the number of Parnssius smintheus (Papilionidae) butterflies moving among 20 alpine meadows separated by varying amounts of forest along the east slope of the Rocky Mountains in Alberta, Canada. We combined generalized additive models and generalized...

The migratory population of Burrowing Owl (Athene cunicularia) in Canada has undergone significant declines over the past five decades. Monitoring of Burrowing Owl includes estimation of annual survival which is predominantly obtained using mark-recapture data. Survival is calculated based on...

From 1996 to 1999, apparent annual survival of male Ovenbirds (Seiurus aurocapillus) was compared in forest fragments created by forestry (n = 3) and agriculture (n = 14) to plots in continuous boreal forest of central Saskatchewan (n = 3). For 398 male Ovenbirds, Cormack-Jolly-Seber models...

Parabolic partial differential equations (PDEs) are used as models of transport-reaction phenomena in a variety of different industrial chemical and materials engineering processes, and can yield precise descriptions of process variables with complex temporal and spatially dependent system...

Pulses of ocean primary productivity during the fall season are frequent in the mid-latitudes when ocean cooling and wind-driven turbulence erode the surface stratification and allow the injection of nutrients into the euphotic zone. This phenomenon is often referred to as a phytoplankton fall...

Endangered species are sensitive to the genetic effects of fragmentation, small population size, and inbreeding, so effective management requires a thorough understanding of their breeding systems and genetic diversity. The Greater Sage-Grouse (Centrocercus urophasianus) is a lekking species that...

Consider an open control volume consisting of a porous medium submerged in a surrounding ambient fluid of density ρa. The top and bottom of the control volume allow ambient fluid to enter the porous medium. Saline fluid of density ρs>ρa is supplied at a constant rate of Qo near the top of the...

Invasive species are a major threat to global biodiversity. Understanding what influences the spread of invasive species after introduction is key to minimizing impacts on native ecosystems and has been the subject of much applied and theoretical work. Thus far, models of spread have not...

Thunderstorms have the potential to produce severe weather and can result in significant financial and human losses. The province of Alberta is one of Canada’s most active thunderstorm regions, with the record for insured damage due to hail. Therefore, it is crucial that thunderstorm forecasts be...

The development of global magnetospheric models, such as Space Weather Modeling Framework (SWMF), which can accurately reproduce and track space weather processes has high practical utility. We present an interval on 5 June 1998, where the location of the polar cap boundary, or open-closed field...
