Plant diversity effects on soil Collembola in boreal forest
(2024)Collembola are one of the most abundant soil fauna in terrestrial ecosystems. They play essential roles in ecosystem processes like litter decomposition. Ongoing biodiversity loss across taxa harms the stability and ... -
Predator mediated indirect effects of livestock on native prey
(2012-11-10)Livestock are common in many protected areas and due to their negative effects pose a considerable challenge to protected area managers attempting to conserve native ecosystems. Negative effects include resource competition ... -
A preliminary study on regional variation in skull morphometrics of Vulpes vulpes in Thunder Bay, ON
(2018)The purpose of this study was to identify whether morphological differences occur between subsets of Red Fox (Vulpes vulpes L.) from different areas in Thunder Bay district. The goal was to examine the statistical output ... -
The response of avian predator populations to forest tent caterpillar (Malacosoma disstria; Lepidoptera: Lasiocampidae) outbreaks in Ontario, Canada
(2020)Outbreaks of insect defoliators have broad ecological effects on forested ecosystems because they can cause extensive mortality in host tree populations. They also represent peaks in the density of food for specialist ... -
Response of Cypripedium and Goodyera to disturbance in the Thunder Bay area
(2018)Orchids constitute a family of rare plants on the landscape that are facing additional threats from anthropogenic changes to their habitat. Orchids have very specific habitat requirements and can be used as early indicators ... -
The response of riffles and pools to changing water contaminants in Sixteen-mile Creek, Halton, Ontario
(2020)Increasing water contaminants has been a growing problem in Southern Ontario due to rapid urbanization, agricultural runoff and pollution. Determining how riffles and pools respond to changing contaminants is crucial to ... -
A review of the Toronto Zoo's head-starting program for recovery of the Blanding's turtle in Rouge Valley National Urban Park
(2024)Conservation reintroduction programs are valuable tools in supporting endangered or extinct species in the wild. With the many ways humans are causing adverse environmental impacts, it is crucial that we put effort into ... -
Social network analysis of lake sturgeon in the Namakan River and Reservoir, Fort Frances District, Ontario
(2017)Social network analysis is the study of individuals or units and the relationship between them at a given time. It allows insight about evolution, maintenance of social relationships, and behavioural characteristics. These ... -
A spatial analysis of the relationship between forest demographic dynamics and diversity under climate change
(2023)Forest dynamics arise from three demographic processes simultaneously, namely recruitment, mortality and growth, all of which are expected to accelerate for the boreal forest under future climate change. Tree species ... -
Stage structure must inform recovery in fish populations: a case for lake sturgeon in the Namakan River, Ontario
(2018)Lake sturgeon are a large bodied, slow maturing, intermittently reproducing acipenserid native to central North America. The species is a conservation concern range-wide because of population declines during the 19th and ... -
Summer distribution, abundance, movements and diet of reintroduced elk (Cervus canadensis) in habitats created by clearcutting in the boreal forest
(2016)Ontario elk restoration program involved 443 elk (Cervus canadensis) from Elk Island National Park, Alberta, re-introduced into four areas of Ontario during 1998-2001. In Northwestern Ontario, the Lake of the Woods (LOW) ... -
Technical and technological alternatives for aerial moose (Alces alces) survey
(2017)Moose (Alces alces) aerial surveys provide the information needed for effective management only when they are accurate and precise. I aimed to identify gaps in and improve understanding of aerial moose surveys in North ... -
Temporal patterns of ungulate vehicle collisions in the Thunder Bay area
(2023)Rising road densities, higher vehicle speed limits, and increased traffic volumes, combined with growth in the density of various deer species, have increased the risk of wildlife-vehicle collisions across the world. The ... -
Testing local adaptation in five populations of Hyalella azteca in northern Alberta’s oil sands region
(2015)Canada’s oil sands hold the third largest petroleum reserves worldwide. Rapid economic growth has led to increased exploitation of the surrounding boreal forest despite limited understanding of the environmental effects ... -
Traditional agroforestry systems as habitat for avian species: assessing their role in conservation
(2019)The objective of this study was to explore the role of traditional agroforestry systems in Ecuador, called chakras, in the conservation of avian species. Eleven examples of chakra, including plantations of yuca (Manihot ... -
Trends in breeding propensity of Common Loons (Gavia immer) in relation to lake water clarity in and around Algonquin Provincial Park
(2023)Productivity of Common Loons has been in decline across most of Canada for several decades. Many environmental factors and human impacts on the breeding grounds may be causing the decline, and these factors are known to ... -
Updates from camera traps used to monitor the elk population in the Lake of the Woods area
(2022)Elk (Cervus elaphus L. canadensis), once widespread across North America, severely declined due to overhunting and habitat conversion in the 1900s. The Lake of the Woods are was one of four locations chosen to reintroduce ... -
The use of citizen science data to predict the winter distribution of the snowy owl in Ontario
(2023)As an Anishinaabe person and environmental scientist, I feel I have an inherent duty to be a steward of the environment. I chose to conduct research on Snowy Owls after learning about the conservation issues affecting ... -
Using a novel methodology to test whether group size affects foraging behaviour in elk
(2012-11-10)Group formation is one of the most striking patterns in the natural world. Elk (Cervus elaphus and C. canadensis) are well known for their social and gregarious nature, but motivations for this behaviour are not fully ... -
Using Canadian migration monitoring network data to assess population changes in Canada Warbler (Cardellina canadensis)
(2023)The Canada Warbler (Cardellina canadensis) has been listed since 2010 as Threatened according to the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) due to significant and long-term declines in the ...
