Fall 2015
Site index is widely used as a measure of forest site productivity, and is an essential input into growth and yield models forecasting forest stand development. However, accurate estimates of site index are frequently difficult or even impossible to obtain, particularly in the boreal mixedwoods...

Examination of the diversity and assembly processes of digenean trematode communities in Alberta, and the implications of spatio-temporal community dynamics on swimmer's itch transmission in recreational lakes
DownloadSpring 2019
The preservation of biodiversity on our planet is crucial to our health. However, we cannot preserve what we do not understand. Biodiversity surveys most often forget to include some of the most diverse organisms on our planet, the parasites. Historically given a bad rap because of the diseases...

Gastropod diversity in the boreal mixedwood forest of northern Alberta - variation among forest types and response to partial harvesting
DownloadFall 2010
Terrestrial gastropods are important decomposers, herbivores, and prey items in forest systems and constitute a poorly understood element of forest biodiversity in Canada. I studied gastropod assemblages in relation to forest cover type and in response to variable retention harvesting in the...

Interactions between the forest tent caterpillar (Malacosoma disstria Hubner) and its natural enemies: the effects of forest composition and implications for outbreak spread
DownloadFall 2011
Forest tent caterpillar (Malacosoma disstria Hübner; FTC), a major defoliator of aspen trees, occupies both aspen and mixedwood forest stands in Alberta’s boreal forest. Forest stand composition could influence the spatial pattern of FTC outbreaks if mortality from natural enemies differs...

Ichnology concerns the study of interactions between organisms and both soft and hard substrates. Actualistic observation of a modern day river channel molluscan assemblage including unionid and sphaeriid bivalves and gastropods within the Saint John River, Fredericton, New Brunswick, Canada...

Seeing the forest for the soil: topographic controls on soil carbon dynamics in the boreal mixedwood forest
DownloadFall 2018
Boreal forest soils store an estimated 272 Pg of carbon. Due to a high degree of spatial heterogeneity, there is a wide range in carbon stores in this ecosystem. Changes in topography and forest structure are important to carbon distribution, influencing the soil microclimate and the chemical...

Using drilled-undrilled shell damage analysis to estimate crushing predation frequencies in modern marine gastropod assemblages
DownloadSpring 2010
Predation is a frequently studied subject, but estimating crushing predation in mollusk communities is challenging. Shells record successful attacks, but it is not always possible to identify attacks on an individual basis. Repair scar frequency is a common proxy for crushing mortality, but shell...
