Timing of breeding, an important driver of fitness in many populations, is widely studied in the context of global change, yet despite considerable efforts to identify environmental drivers of seabird nesting phenology, for most populations we lack evidence of strong drivers. Here we adopt an alternative approach, examining the degree to which different populations positively covary in their annual phenology to infer whether phenological responses to environmental drivers are likely to be (i) shared across...

Future seasonal changes in habitat for Arctic whales during predicted ocean warming

Philippine Chambault, Kit M Kovacs, Christian Lydersen, Olga Shpak, Jonas Teilmann, Christoffer M. Albertsen & Mads Peter Heide-Jørgensen
Ocean warming is causing shifts in the distributions of marine species, but the location of suitable habitats in the future is unknown, especially in remote regions such as the Arctic. Using satellite tracking data from a 28-year long period, covering all three endemic Arctic cetaceans (227 individuals) in the Atlantic sector of the Arctic, together with climate models under two emission scenarios, species distributions were projected to assess responses of these whales to climate change...

Data from: Glacial ice supports a distinct and undocumented polar bear subpopulation persisting in late 21st-century sea-ice conditions

Polar bears are susceptible to climate warming because of their dependence on sea ice, which is declining rapidly. We present the first evidence for a genetically distinct and functionally isolated group of polar bears in Southeast Greenland. These bears occupy sea-ice conditions resembling those projected for the High Arctic in the late 21st century, with an annual ice-free period that is >100 days longer than the estimated fasting threshold for the species. Whereas polar bears...

Searching for genetic evidence of demographic decline in an arctic seabird: beware of overlapping generations

Emeline Charbonnel, Claire Daguin, Lucille Caradec, Eléonore Moittié, Olivier Gilg, Maria Gavrilo, Hallvard Strom, Mark L Mallory, Grant Gilchrist, R. I. Guy Morrisson, Raphael Leblois, Camille Roux, Jonathan M Yearsley, Glenn Yannic & Thomas Broquet
Genetic data are useful for detecting sudden population declines in species that are difficult to study in the field. Yet this indirect approach has its own drawbacks, including population structure, mutation patterns, and generation overlap. The ivory gull (Pagophila eburnea), a long-lived Arctic seabird, is currently suffering from rapid alteration of its primary habitat (i.e., sea ice), and dramatic climatic events affecting reproduction and recruitment. However, ivory gulls live in remote areas, and it is...
