Introducing shrubs enhances the representation of high-latitude vegetation and carbon cycling in the ORCHIDEE land surface model

Arctic–Boreal terrestrial ecosystems are rapidly changing under amplified high-latitude warming, including widespread expansion of shrubs, with consequences for regional carbon and energy balances. Yet, high-latitude vegetation diversity and vegetation–climate interactions remain...

Stroke rate detection from accelerometer data on marine mammals

Overall dynamic body acceleration (ODBA) is widely used as a proxy for movement activity. However, for large, slow-moving animals such as cetaceans, ODBA is dominated by orientational shifts rather than dynamic movements. We argue for using stroke rate frequency as an alternative...

The chemical composition of narwhal tusk and tooth is impacted by geographical locality

Abstract The possible relationship between diet and geographical locality is important for understanding the putative effects of climate change on animal behaviour and survival. Narwhals have two maxillary teeth, one of which may become a tusk. In these teeth, various chemical el...

Evaluating harvest risk with limited data: A case study on polar bears ( Ursus maritimus ) in East Greenland

Abstract Evaluating the impact of human‐caused removals on wildlife is challenging, especially when population data are limited, future monitoring is uncertain, and habitat conditions are changing. The East Greenland (EG) polar bear subpopulation contains 2275 animals (95% CI = 1...
