Arctic geese in newly colonised, colder breeding areas have higher spring body mass and breed earlier relative to the onset of spring Moving to colder areas allows arctic geese to reduce the negative effects of climate change (trophic mismatch), but this comes at a price for parents as they face harsher nesting conditions (snow cov...

Hi. Colonizing colder Arctic zones enables pink-footed geese to realign breeding with spring onset, yet demands greater parental body reserves. Climate change drives and facilitates this shift, producing heterogeneous effects across individuals depending on their physiological quality 🌎

Dette er årsaka til at gåtefullt tjern i Stad skiftar farge Det går frå sitrongult, grønt til blodraudt. No har forskarar funne svaret på kvifor. – Ein litt morosam kuriositet.

Fargerik økologi og biologi på Nordvestlandet. Har sett slike blodraude dammar sjølv, bare litt lenger sør, på øya Frøya i Bremanger. Rock pool Haematococcus algae

Visited Runde again today. The Northern Gannets, with their long breeding season, are still around. Decent number of recruits as far as I could judge through the binoculars. Morus bassanus, havsule.

Blue mussels in western Norway have vanished where in reach of crawling predators

The study is a follow-up on Nadja´s master project, which led to this article:

We're getting some cracking photo submissions to the Gulls Eating Stuff project! Here are a few showing gulls predating a coot chick, a vole, a mole (!) and a GBBG that has just killed an adult moorhen. Keep 'em coming! Submit your photos of gulls eating stuff to citsci.org/projects/gul....

NOAA firings hit the birthplace of weather and climate forecasting Dismissed researchers were improving severe weather predictions

Hi - I'd like to share this story of what is happening at NOAA GFDL, where some of my colleagues and I worked until the mass firings at NOAA last week.
