First recorded ice entrapment of a beluga whale (Delphinapterus leucas) in east Greenland
Beluga whales are rare along the coast of east Greenland and the closest recognized stock occurs around Svalbard. Here we report on an ice entrapment of an adult beluga whale (Delphinapterus leucas) in north-east Greenland.

The paucity of observations of wild polar bears (Ursus maritimus) caching of food (including hoarding, i.e., burying and remaining with a kill for up to a few days) has led to the conclusion that such behavior does not occur or is negligible in this ...

Morphology of the lingual papillae of the polar bear (Ursus maritimus).
We examined the dorsal lingual surfaces of a newborn and an old polar bears by using scanning electron microscopy. In the newborn polar bear, the filiform papilla on the lingual apex was cylindrical in shape. The connective tissue core of the filiform papillae was needle-shaped and that of the fungiform papillae was funnel-shaped. The filiform papillae

Archival Swedish newspapers from the 18th to 20th centuries reveal that the Baltic harbour porpoise once utilized the waters along the full Swedish coast, reaching far north into the Gulf of Bothnia, areas where it no longer occurs today. These records show a major range loss and highlight the importance of historical baselines for conservation ...

Element concentrations in tissues reveal spatial structure of Atlantic walrus management stocks
Differences in tissue element concentrations confirm geographic differentiation between 2 of Canada's walrus management stocks but reveal additional spatial structure within the largest stock that may have management implications. Abstract Ensuring harvested animal populations are managed at appropriate scales requires an understanding of underlying ...

Developing Multi-Level Institutions from Top-Down Ancestors
The academic literature contains numerous examples of the failures of both top-down and bottom-up common pool resource management frameworks. Many authors agree that management regimes instead need to utilize a multi-level governance approach to meet ...

This study found that over 10% of wild birds in Lahore, Pakistan, carry antibodies for Toxoplasma gondii, a parasite that can cause serious illness in humans and animals. Birds like lapwings and silver bills showed especially high antibody rates. Improved monitoring is needed to better understand risk dynamics in Pakistan.

No need to replace an “anomalous” primate (Primates) with an “anomalous” bear (Carnivora, Ursidae)
By means of mitochondrial 12S rRNA sequencing of putative “yeti”, “bigfoot”, and other “anomalous primate” hair samples, a recent study concluded that two samples, presented as from the Himalayas, do not belong to an “anomalous primate”, but to an ...
