Factors influencing dispersal by flight in bark beetles (Coleoptera: Curculionidae Scolytinae): from genes to landscapes.Download
Dispersal by flight is obligatory for bark beetles in the subfamily Scolytinae. Adult bark beetles must leave the natal host and fly to seek new hosts for brood production. Because of the eruptive nature of some bark beetle populations, dispersal capacity has implications for beetle spread and...
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 SurvivalDownload
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...
Birds of a feather do not always lek together: Genetic diversity and kinship structure of Greater Sage-Grouse (Centrocercus urophasianus) in AlbertaDownload
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...

Code and data for "Biased correlated random walks and invasive spread: Insights from the alga Codium fragile"Download
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...
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...
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...
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...
The preparation of sourdough in bakeries may include the use of inocula, e.g. fruits, flowers or rumen cuts to accelerate the process of selection of suitable microorganisms. The aim of this work was to investigate the effect of these inocula on the microbial evolution in sourdoughs. First, the...
