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...

The Level of Traffic Stress (LTS) framework is widely used to assess the suitability of roadway environments for cycling. Its main strength is the identification of infrastructure characteristics that meet the needs of different cyclist groups. The four levels of infrastructure ratings, LTS 1 to...

Identification of genes and gene expression associated with dispersal capacity in the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae)
Download2021-07-01
Shegelski, Victor A., Evenden, Maya L., Huber, Dezene P. W., Sperling, Felix A. H.
Dispersal flights by the mountain pine beetle have allowed range expansion and major damage to pine stands in western Canada. We asked what the genetic and transcriptional basis of mountain pine beetle dispersal capacity is. Using flight mills, RNA-seq and a targeted association study, we...

Flight polyphenisms naturally occur as discrete or continuous traits in insects. Discrete flight polyphenisms include winged and wingless morphs, whereas continuous flight polyphenisms can take the form of short- or long-distance fliers. The mountain pine beetle (Dendroctonus ponderosae) exhibits...

Trade-offs between dispersal and reproduction are known to be important drivers of population dynamics, but their direct influence on the spreading speed of a population is not well understood. Using integrodifference equations, we develop a model that incorporates a dispersal–reproduction...

Factors influencing dispersal by flight in bark beetles (Coleoptera: Curculionidae Scolytinae): from genes to landscapes.
Download2019-01-01
Jones, Kelsey L., Shegelski, Victor A., Marcelis, Nathan G., Wijerathna, Asha N., Evenden, Maya L.
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...

Analyzing Network Connectivity by Cyclist Comfort: An Empirical Reappraisal of the Four Types of Cyclists Typology and Level of Traffic Stress Framework
DownloadFall 2019
North America is seeing a resurgence of interest in cycling both for recreation and as a transportation mode. Cycling is touted as a means to reduce traffic congestion and its GHG emissions and pollution, increase livability, and provide a remedy to inactivity and its related health problems....

Testing for trade-offs between flight and reproduction in the mountain pine beetle (Coleoptera: Curculionidae) on two pine hosts
Download2019-01-01
Wijerathna, Asha, Whitehouse, Caroline, Proctor, Heather, Evenden, Maya
Mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae) adults fly to disperse before host colonization. The effect of flight on reproduction was tested by comparing the number and quality of offspring from beetles flown on flight mills to that of unflown...

Cabral, L., Kim, A. M., Shirgaokar, M.
Studies have shown that a network of safe, connected, and direct facilities can increase urban cycling levels. During summer 2017, the city of Edmonton, Canada, constructed nearly 20 kilometers of protected bicycle lanes on its core neighborhood streets. A rapid and coordinated network...

SSHRC Awarded IDG 2019: This IDG project aims at developing an inclusive approach to landscape by studying it through the lens of 'biography' and using cutting edge methods of archaeological prospection. I have selected a test area of 600 hectares of forested countryside in Achaia Phthiotis, a...
