The Effects Of Ecotourism On Polar Bear Behavior
Polar bears spend the majority of their lives on the sea ice, where they gain access to seals and mates. In western Hudson Bay, the sea ice melts for three to four months in the summer, and polar bears there are forced onto land. These bears live on their fat reserves for the duration of the …

Indigenous Knowledge of Human–Polar Bear Coexistence in Churchill, Manitoba
Polar bears (wapusk; nanuq; sas; loor blaan; Ursus maritimus) and people have shared northern coastlines for time immemorial, yet concerns about polar bears coming into communities is increasing. As the Arctic warms and sea ice habitat declines due to climate warming, coexistence strategies between …

Polar Bear (Ursus Maritimus) Foraging Ecology in the Western Canadian Arctic
… declines in sea ice over the past three decades. Polar bears (Ursus maritimus) rely on sea ice as their primary habitat to hunt marine mammal prey. Due to their position at the top of the Arctic marine food web, polar bear foraging patterns can provide insights on ecosystem structure and function …

Knowing Misha the Polar Bear: Multi-naturalism, biography, and conservation in Svalbard.
… putative epoch, it explores the idea of ‘knowing polar bears’ in Svalbard. By this I refer to how, through a succession of different interactions within a dynamic actor-network, human actants come to understand Svalbard polar bears. I acknowledge that these encounters are not valueless, instead …

Using Minimally Invasive Sampling Methods to Evaluate Polar Bear (Ursus maritimus) Visitation in Response to Environmental and Anthropogenic Stimuli
Polar bears (Ursus maritimus) are spending more and more time on land in an increasingly warming Arctic, raising concerns for both human safety and polar bear conservation. This research aimed to investigate the ecological and anthropogenic influences on polar bear visitation to infrastructure in …

The Role of Scientific Uncertainty in Polar Bear Conservation Policy: A Descriptive Analysis
Abstract In recent years, the polar bear (Ursus maritimus) has become synonymous with the climate change movement. Prior to concerns over global warming, the biggest threat to polar bears was overharvest and trophy hunting. For decades, policies successfully mitigated population declines as a …

Mitochondrial Haplotype Influences the Impact of Simulated Climate Warming on a Tropical Ectotherm
While the plight of polar bears in a rapidly warming world is much publicized, recent theory suggests that the organisms likely to be most at risk from rising temperatures are terrestrial arthropods and reptiles inhabiting the tropics. In such ectothermic species, metabolic rate increases …

Modelling the Impact of Climate Change on the Polar Bear Population in Western Hudson Bay
… is to model the impact of climate change on polar bear populations. The first model is a discrete matrix model with time-dependent parameters, which are influenced by temperature increases. Sensitivity analysis is done on the model. Numerical simulations predict there exist several scenarios …
