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...

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...

Disentangling detoxification: Gene expression analysis of feeding mountain pine beetle illuminates molecular-level host chemical defense detoxification mechanisms
Download2013-01-01
Bohlmann, Jörg, Bonnett, Tiffany R., Pitt, Caitlin, Keeling, Christopher I., Yuen, Macaire M. S., Huber, Dezene P. W., Robert, Jeanne A.
The mountain pine beetle, Dendroctonus ponderosae, is a native species of bark beetle (Coleoptera: Curculionidae) that caused unprecedented damage to the pine forests of British Columbia and other parts of western North America and is currently expanding its range into the boreal forests of...

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...

Effect of age of the intermediate host Tribolium confusum (Coleoptera) on infection by Hymenolepis diminuta (Cestoda).
Download2008
A cross-sectional study of 27 cohorts of Tribolium confusum aged 2–78 wk was done to examine effects of host age on exposure to eggs of Hymenolepis diminuta under standardized conditions. Pre-exposure, fasting, and postexposure mortality were low, sex ratio was equal, and fecundity of hosts was...

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...

How the mountain pine beetle (Dendroctonus ponderosae) breached the Canadian Rocky Mountains
Download2014-01-01
Sperling, Felix A. H., Murray, Brent W., Li, Yisu, Coltman, David W., Bohlmann, Joerg, Janes, Jasmine K., Cooke, Janice E. K., Boone, Celia K., Huber, Dezene P.W., Keeling, Christopher I., Yuen, Macaire M. S.
The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins), a major pine forest pest native to western North America, has extended its range north and eastward during an ongoing outbreak. Determining how the MPB has expanded its range to breach putative barriers, whether physical...

Integrated step selection analysis: Bridging the gap between resource selection and animal movement
Download2016-01-01
Avgar, Tal, Potts, Jonathan R., Lewis, Mark A., Boyce, Mark S.
A resource selection function is a model of the likelihood that an available spatial unit will be used by an animal, given its resource value. But how do we appropriately define availability? Step selection analysis deals with this problem at the scale of the observed positional data, by matching...

Migration and survival of Parnassius smintheus: Detecting effects of habitat for individual butterflies
Download2004
Hanski, I., Roland, J., Matter, S. F., Moilanen, A.
We examined the migration and survival of the butterfly Parnassius smintheus in a heterogeneous landscape consisting of 21 habitat patches imbedded in a matrix of meadow and forest habitat. We modified an existing mark-release-recapture model to account for multiple habitat types and fit the...
