Observation of a Polar Bear with Rabies [PDF]

Journal of Wildlife Diseases, 1991
On 1 November 1989 the first confirmed case of rabies in a polar bear (Ursus maritimus) was encountered by Inuit hunters in the vicinity of Cape Kendall, Southampton Island, Northwest Territories (Canada). The adult male polar bear had posterior paralysis.

IMMOBILIZATION OF POLAR BEARS WITH CARFENTANIL [PDF]

Journal of Wildlife Diseases, 1983
Sixty-four free-ranging polar bears (Ursus maritimus) were immobilized using carfentanil at doses ranging from 1.0–38.0 μg/kg (mean 20 ± 8 μg/kg). Induction was rapid (5.0 min) (n = 46) and the bears showed good muscle relaxation. Respiratory rate was depressed (mean 3.8 bpm). The mean arousal after the administration of narcotic antagonists was longer

Toward a non‐invasive inuit polar bear survey: Genetic data from polar bear hair snags

Wildlife Society Bulletin, 2013
We explore the feasibility of collecting microsatellite genotypes of non‐invasively collected hair from free‐ranging polar bears (Ursus maritimus) in M'Clintock Channel, Nunavut, Canada.

Ikona, świadek, ofiara. Niedźwiedź polarny jako figura wizualna dyskursu zmiany klimatu

Zagadnienia Rodzajów Literackich, 2021
The article focuses on the media practice of using visual representations of polar bears to illustrate information about climate change. It starts with a short description about the iconic status that climate discourse attributes to these type of images.

Polar Bears in a Warming Climate [PDF]

Integrative and Comparative Biology, 2004
Polar bears (Ursus maritimus) live throughout the ice-covered waters of the circumpolar Arctic, particularly in near shore annual ice over the continental shelf where biological productivity is highest. However, to a large degree under scenarios predicted by climate change models, these preferred sea ice habitats will be substantially altered.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

FEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Capturing environmental DNA in snow tracks of polar bear, Eurasian lynx and snow leopard towards individual identification

Frontiers in Conservation Science, 2023
Polar bears (Ursus maritimus), Eurasian lynx (Lynx lynx) and snow leopards (Panthera uncia) are elusive large carnivores inhabiting snow-covered and remote areas.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Mobilization of Inuit Qaujimajatuqangit for polar bear co-management: qualitative analysis of a Nunavut Wildlife Management Board public hearing

Arctic Science
Inclusion of Indigenous knowledge in polar bear (nanuq [Inuktut]; Ursus maritimus) conservation and management decisions remains an enduring challenge. The Nunavut Wildlife Management Board (NWMB) held a series of public hearings on polar bear management
