Observed and forecasted changes in land use by polar bears in the Beaufort and Chukchi Seas, 1985–2040

Global Ecology and Conservation, 2022
Monitoring changes in the distribution of large carnivores is important for managing human safety and supporting conservation. Throughout much of their range, polar bears (Ursus maritimus) are increasingly using terrestrial habitats in response to Arctic

Effects of sea ice decline and summer land use on polar bear home range size in the Beaufort Sea

Ecosphere, 2021
Animals responding to habitat loss and fragmentation may increase their home ranges to offset declines in localized resources or they may decrease their home ranges and switch to alternative resources.

Habitat use and selection patterns inform habitat conservation priorities of an endangered large carnivore in southern Europe

Endangered Species Research, 2021
Understanding the habitat use and selection patterns of endangered species is essential in developing management measures that will protect critical habitat and mitigate human-wildlife conflicts. This understanding is particularly important in areas with

Integrative description of two new Milnesium species (Apochela: milnesiidae) from Canada and Nepal

The European Zoological Journal
Global knowledge of tardigrade diversity is limited, and there are still regions with poorly studied fauna. We applied an integrative taxonomy approach to describe two new eutardigrade species from Nepal and Canada.
