How do dolphins learn to live along the coast?
Ocean-dwelling dolphins have repeatedly adapted to life in coastal areas throughout history.

The Norwegian wolf is extinct
The Norwegian wolf died out in the wild a long time ago. The wolves in Norwegian forests today are Finnish. Inbreeding is making them prone to extinction as well.
How a small fish coped with being isolated from the sea
A 12 000-year-old stickleback shows how species adapt.
When does the green-eyed monster of jealousy awake in people?
Women and men are often jealous for completely different reasons. This gender difference occurs so early that it surprised the researchers.
New species discovered in Norway
This brand new species of cuckoo wasp was discovered because of its own language.
Darwin had Galapagos finches. Norway has… house sparrows?
Uncommon lessons learned from the world’s most widespread bird.
Global warming is faster than evolution
If global warming happens too quickly, not all species will be able to adapt in time.
NTNU researcher wins ERC Consolidator Grant
The EU has awarded two million euros for research on how animals are coping with climate changes.
Inbreeding detrimental for survival
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.
Panthera leo’s family tree takes shape
Once upon a time, lions were the world’s most widespread mammals. Now we know more about their genealogy – and that could make it easier to help the species survive.
How Darwin can help us with cancer and corona
Why do some organisms evolve and others don’t? The answer could help in the fight against both cancer and corona.
A tiny arctic shrub reveals secrets of plant growth on Svalbard
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.
Mystery of the blunt-tipped beetle penis
It took seven years, countless beetle penis field investigations, and hours upon hours on hands and knees in coastal wetlands. This is the story of all the research that has to happen before a new species can finally get its official name.
Thinking outside the box of fossils
During the time of Darwin, anthropogeny was the study of human origins. Its sub-discipline paleoanthropology has since taken over, which focuses on fossils found in dry parts of Africa. These fossils don’t tell us much about why or where humans actually evolved.
Svalbard reindeer populations rebounding from centuries of hunting
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.
Planting the seeds for a bioliterate tropical country
Ecologist Daniel H. Janzen has spent virtually all of his half-century career trying to catalogue and understand the creatures in a patch of dry tropical forest in northwestern Costa Rica. Little did he realize his efforts would evolve into building a sea-to-summit conservation area — and a drive to inventory all million species in the country in partnership with the Costa Rican government.
How do species adapt to their surroundings?
Several fish species can change sex as needed. Other species adapt to their surroundings by living long lives — or by living shorter lives and having lots of offspring. The ability of animals and plants to change can sometimes manifest in apparently extreme ways.
Willow tits survive best with support from a flock
Flock status is crucial for small birds struggling to survive the winter. Those with the lowest status face tough odds.
How plants respond to attacks
Plants have to defend themselves against drought, enemies and disease. But different threats demand different responses. So how do plants know what’s attacking them?
Norwegian public asked to name a species
The moss world will never be the same. The moss Norwegian researchers thought they knew has played a trick on them. In return, researchers are calling on the Norwegian public to name a new species.
Museums can give us better beer, paint and omega-3
Natural history collections aren’t just dusty financial sinkholes. Actually, they can be gold mines for industry.
Using Tinder doesn’t result in more casual sex
Tinder users don’t have more sexual partners than other similarly minded people. Women tend to use the app to feel better about themselves, whereas men are more focused on sex.
In the bullfinch world, she gets to decide
A lot of birdwatchers like the bullfinch. They’ve probably noticed that the female can chase off the more colourful male from the bird feeder. That makes this species different.
Vampire bats’ bloody teamwork
Vampire bats are the only mammals that feed exclusively on blood. The way they manage to do that offers us some remarkable insights into evolution.
