Models of population dynamics are a central piece for harvest management, allowing managers to evaluate alternative strategies and to identify uncertainty. Here we present a density-dependent population dynamics model that can be used in conjunction with adaptive management to optimize big game...

An adaptive approach to endangered species recovery based on a management experiment: reducing moose to reduce apparent competition with woodland caribou
DownloadFall 2013
Species that are rare yet widely distributed are among the most challenging to conserve. The mountain ecotype of woodland caribou (Rangifer tarandus) is declining because of apparent competition with non-caribou ungulates (NCU) such as moose (Alces alces). I experimentally assessed whether...

We quantified supplemental sources of calcium in the diet of nestling Tree Swallows (Tachycineta bicolor) near acid sensitive lakes in northwestern Ontario. Among the calcium-rich items brought to nest boxes by adult swallows and ingested by nestlings, fish bones (particularly flat pieces) were...

The resilience of coastal social-ecological systems may depend on adaptive responses to aquaculture disease outbreaks that can threaten wild and farm fish. A nine-year study of parasitic sea lice (Lepeophtheirus salmonis) and pink salmon (Oncorhynchus gorbuscha) from Pacific Canada indicates that...

Dall sheep (Ovis dalli dalli), grizzly bear (Ursus arctos) and wolf (Canis lupus) interactions in the Northern Richardson Mountains, Canada
DownloadFall 2012
Lambert Koizumi, Catherine M S
Assessing the impact of predators on a prey population is inherently challenging, a fortiori in remote ecosystems. With this thesis, I studied the interactions between a recently declining Dall sheep (Ovis dalli dalli) population and two predators: grizzly bears (Ursus arctos) and wolves (Canis...

Density-dependent variation in lifetime breeding success and natural and sexual selection in Soay rams
Download1999
Smith, J.A., Bancroft, D.R., Clutton-Brock, T.H., MacColl, A.D., Pilkington, J., Coltman, D.W., Pemberton, J.M.
Variation in male lifetime breeding success (LBS) is central to understanding selection, yet it has rarely been measured in natural populations of large mammals. Here, we first describe variation in the opportunity for selection in cohorts of Soay rams (Ovis aries) on the archipelago of St....

Intrapopulation variability in wolf diet revealed using a combined stable isotope and fatty acid approach
DownloadSpring 2018
Naturally occurring stable isotope ratios and fatty acids are two types of chemical biomarkers frequently used to quantitatively estimate consumer diets. Stable isotope values in animal tissues and diets have been evaluated using Bayesian mixing models to provide dietary estimates of consumers in...

Fall 2014
Multiple carnivore species can have greater population limiting effects than single carnivores. Two coexisting carnivores can only be similar up to a certain extent. I investigate how two carnivores, wolves (Canis lupus) and cougars (Puma concolor), coexist through niche partitioning in the...
