Feeding frenzies of baleen whales along East Greenland
Recent ecological shifts along East Greenland's coast have resulted in unprecedented feeding frenzies by boreal baleen whales. Driven by rising sea temperatures and diminished sea ice since the late 1990s, fin, humpback, and minke whales—now numbering approximately 4,000 humpbacks, 6,000 fin whales, and 4,500 minkes—are regularly observed feeding as far north as 70°N. These whales consume an estimated 1 million tonnes of prey annually, largely capelin and krill, whose distribution has shifted from Icelandic waters. This borealization of the East Greenland marine ecosystem highlights significant
Pagophilic rather than sea ice obligate: effects of sea ice and colony size on Adélie penguin molt location
Adélie penguins, long considered sea ice obligates, may exhibit greater habitat flexibility than previously understood. Recent research, synthesizing extensive historical data and 12 years of camera observations at Cape Royds, Antarctica, reveals a nuanced relationship between sea ice conditions, colony size, and molt location. Findings demonstrate a negative correlation between January sea ice concentration and peak molt counts, alongside a link to breeding population size.
