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...

Annual Dispersal of Endangered Burrowing Owls (Athene cunicularia): Implications for Estimating Survival
DownloadSpring 2022
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...

Assessment of current and future needs for entomological extension in agriculture in Alberta
DownloadSpring 2024
Recent changes to the structure of agricultural extension in Alberta have raised concerns about the effectiveness and efficiency of the system. There is a need to evaluate the effectiveness of the current agricultural extension system to identify opportunities for growth and collaboration....

Birds of a feather do not always lek together: Genetic diversity and kinship structure of Greater Sage-Grouse (Centrocercus urophasianus) in Alberta
Download2010
Aldridge, C.L., Bush, K.L., Coltman, D.W., Carpenter, J.E., Paszowski, C.A., Boyce, M.S.
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...

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...

Ripari, Valery, Gänzle, Michael G.
Sourdough has traditionally been used as leavening agent in artisanal baking. The production of baked and steamed cereal products increasingly employs sourdough as baking improver to achieve improved bread quality, or to obtain “clean label” products. Sourdoughs are maintained in bakeries by...

Delimitation and identification of crescent butterflies (Nymphalidae: Phyciodes) in Alberta using molecular and morphological techniques
DownloadFall 2022
Species delimitation can be challenging, especially in taxonomic groups that exhibit little morphological divergence. Many techniques and concepts have been developed for detecting species boundaries, and molecular methods are becoming increasingly common. Next generation sequencing techniques...

Models that describe the spread of invading organisms often assume that the dispersal distances of propagules are normally distributed. In contrast, measured dispersal curves are typically leptokurtic, not normal. In this paper, we consider a class of models, integrodifference equations, that...
