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...

Human food production activities can dominate natural systems, altering ecological and evolutionary aspects of the environment. Disease-mediated interactions are of particular concern. For example, parasites may "spill-over'' from farms to wildlife. Parasites isolated on farms can evolve...

Embedded Categories: Three Studies on the Institutional Shaping of Categories and Category Effects
DownloadSpring 2012
Over the past fifteen years, a rich program of research has emerged among scholars interested in the role of categories within fields and industries. In this context, studies have shown that categories shape organizational and market processes by grouping firms and products in ways that convey...

Estimating animal abundance in industrial scale batches of ground meat is important for mapping meat products through the manufacturing process and for effectively tracing the finished product during a food safety recall. The processing of ground beef involves a potentially large number of...

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...

Evolution of sourdough microbiota in spontaneous sourdoughs started with different plant materials

Ripari, Valery, Gänzle, Michael G., Berardi, Enrico
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...

Exploration of Microscopic Structure and Dynamics in Halide Perovskite and Perovskite−Inspired Materials with Solid-State NMR Spectroscopy
DownloadSpring 2022
The work presented in this thesis describes the synthesis, structure, and optical properties of three different classes of halide-based perovskite materials, namely, metal halide perovskites of ABX3 type, halide double perovskites of A2B'B"X6 type, and “vacancy-ordered perovskites” of A2BX6 type...

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...

Factors Influencing Mountain Pine Beetle (Coleoptera: Curculionidae: Scolytinae) Dispersal by Flight and Subsequent Trade-off Between Beetle Flight and Reproduction
DownloadFall 2016
The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), has an obligatory dispersal phase before selection of a suitable host for brood production. Flight during the dispersal phase is affected by both beetle physiology and environmental factors....

While many studies have evaluated wildlife passage effectiveness, few have explored how accurately passage activity can be modelled. I created a habitat suitability index (HSI) model for American mink (Neovison vison) using Geographic Information Systems with 17 wildlife passages located in Quebe...
