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

open access: yesArctic 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

The numbers of ringed seals (Phoca hispida) in Baffin Bay and associated waters

open access: yesNAMMCO Scientific Publications, 1998
The size of the population of ringed seals (Phoca hispida) inhabiting Baffin Bay and associated waters was estimated by two methods. An approximate model of the energetics of the polar bear (Ursus maritimus) estimated an energetic need of about 16,000 MJ/

The polar bear Ursus maritimus feeding in a seabird colony in Frans Josef Land

open access: yes, 1993
During the second half of August 1992 polar bears were observed feeding intensively in the little auk Alle alle colony on Rubini Rock, Hooker Island, Frans Josef Land. They dug out nests eating eggs, chicks and adult birds. Their activity results in both

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

open access: yesMolecular 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.

Efficacy of deterrents for mitigating human‐polar bear conflict in northern Alaska

open access: yesWildlife Society Bulletin
A warming climate is negatively affecting Arctic species that rely on sea ice to perform their life history activities. Changing sea ice dynamics have led polar bears in many subpopulations to spend more time on land, increasing the potential for human ...

The Role of Satellite Telemetry Data in 21st Century Conservation of Polar Bears (Ursus maritimus)

open access: yesFrontiers in Marine Science, 2022
Satellite telemetry (ST) has played a critical role in the management and conservation of polar bears (Ursus maritimus) over the last 50 years. ST data provide biological information relevant to subpopulation delineation, movements, habitat use, maternal

Trichinella sp. in polar bears from Svalbard, in relation to hide length and age

open access: yes, 2010
Diaphragm and masseter muscles from 376 polar bears ((irsur maririmus), 252 ringed seals (Phocn hispida), 84 bearded seals (Erignarhus barbarus), and 77 arctic foxes (Alopex lagopus) from Svalbard were examined for Trichinelln.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

open access: yesMolecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Community-led non-invasive polar bear monitoring in the Eeyou Marine Region of James Bay, Canada: insights on distribution and body condition during the ice-free season

open access: yesFACETS, 2023
Wildlife conservation is informed by detailed understanding of species demographics, habitat use, and interactions with environmental drivers. Challenges to collecting this information, particularly in remote places and on widely ranging species, can ...

Low protein variability and genetic similarity between populations of the polar bear (Ursus maritimus)

open access: yes, 2010
Blood samples from a total of 460 polar bears (Ursus maritimus) from various Arctic regions, but excluding the USSR, were collected during the period 1967-1981 to study electrophoretic variation in different proteins.
