The microscopic, free-floating algae called phytoplankton — and the tiny zooplankton that eat them — are notoriously difficult to count. Researchers need to know how a warming climate will affect them both. A new kind of smart, lightweight autonomous underwater vehicle (LAUV) can help.
Uncommon lessons learned from the world’s most widespread bird.
The polar night is dark — if you’re a person. But not if you’re a krill or a seabird or a fish. In the first episode of NTNU’s new English-language podcast, 63 Degrees North, learn how researchers discovered that there’s more than enough light in the polar night for the tiny creatures who live there.
Barnacle geese in the Arctic have been on a diet. So many now migrate to northern breeding grounds that in some places there’s less food to go around. The good news is that it doesn’t seem to restrict their population growth — yet.
The EU has awarded two million euros for research on how animals are coping with climate changes.
The great tit and other birds can adapt to changes in their food supply as a result of climate change, but they run into trouble if the changes happen too quickly.
Dopamine can trigger feelings of happiness in humans. Water fleas that are exposed to dopamine-regulating substances apparently gain several advantages.
Inbred birds don’t live as long and have fewer offspring than non-inbred birds. Inbreeding is equally harmful regardless of where the birds live.
Bats have received a lot of negative attention, but the chances are slim that the virus that causes COVID-19 was transmitted from bats to humans. The world needs bats – in ecosystems, for pollination and for seed dispersal. On top of that, they keep harmful insects in check around our homes, on farms and in cities.
It’s not easy being a tiny willow on the wind-and snow-blasted islands of the Norwegian territory of Svalbard. It turns out that Salix polaris, the polar willow, handles these tough conditions by growing as best it can in response to July temperatures — a response that researchers recorded all over the archipelago.
With some practice, you can learn to recognize some of the most common birds in northern Europe by their songs.
If artificial light shines into the Arctic Ocean during the polar night, does it matter? A new paper in Communications Biology says the answer to this is a strong yes.
A group of polar bear researchers wants you to do more than worry about the fate of these beautiful animals. They’ve calculated how much summer sea ice is melted per metric tonne of CO2 emissions. Then you can decide if the flight you’re planning to take is worth destroying polar bear habitat.
As forest areas shrink and become fragmented, many tree species face problems. They often rely on animals that can no longer disperse their seeds effectively.
Bushfires are a normal part of the cycle of nature in Australia. But not like this. And it is going to get worse.
Several high-profile studies report that ocean acidification will affect coral reef fish behaviour enough to jeopardize their survival. One research team looked more deeply at this assertion — and found it is simply not true.
Researchers wanted to involve local people living around Kenya and Tanzania’s Serengeti-Mara parks in developing a sustainable future for them and the parks. They developed a board game to get people talking to the researchers — and to each other. That game has now won an international award.
As reindeer go, the animals living on Svalbard might not be Santa’s first choice. They’re a smaller subspecies of their common mainland relatives, and to save energy they basically never run. But because they were nearly exterminated from Svalbard around 1900 — and were then protected in 1925 — the animals provide unique insights into how conservation can help species thrive.
The Arctic’s once impenetrable ice cap is melting away, with profound consequences for everything from ocean circulation patterns to fish numbers and diversity. The Nansen Legacy Project, including NTNU biologists, chemists and engineers, is working to better understand what these changes mean for the Barents Sea and the Arctic Basin
