The landscape used by eight bat species in the Nipigon District, Ontario
(2018)Emergent diseases such as white nose syndrome (WNS) and habitat loss are negatively affecting the populations of Ontario bat species. There are eight bat species native to Ontario: Estesicus fuscus, Lasiurus cinereus, L. ... -
Limitations of forest overstory composition and age as proxies for habitat in a harvested boreal forest
(2014-12-11)Despite the importance of wildlife habitat protection in meeting land use management objectives, criteria for habitat identification are surprisingly amorphous. For example, while much current habitat modeling has tended ... -
Metapopulation viability analyses of woodland caribou in the Lake Superior range
(2022)Woodland caribou populations in the Lake Superior range have deteriorated. The caribou’s decline follows industry growth since the 1900s. Islands like those in Slate Islands Provincial Park, Michipicoten Island and Caribou ... -
Methods for finding wolf (Canis lupus) kill sites using location clusters: a study in Grand Portage Indian Reservation, Minnesota
(2020)Wolves have profound effects on the ecosystems around them. As large carnivores, they can significantly manipulate ecosystems by controlling potentially overabundant ungulate populations. This study attempts to find predation ... -
Natural resource management and Indigenous food systems in Northern Ontario
(2014-12-16)The forests and freshwaters of Northern Ontario are complex socio-ecological systems that have provided opportunities to sustain local lives, economies, and cultures since time immemorial. Through nation-to-nation ... -
Nesting dynamics of the scarlet ibis (Eudocimus ruber) in Trinidad, West Indies
(2009)The effect of human disturbance on colonial waterbirds is a global issue. Many colonial waterbirds are migratory, and their protection depends on balancing conservation of their habitats and habits across many regions. ... -
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 ...
