Supergenes helped bring alien plant to Norway
The plant is called common ragweed, and if you are allergic to pollen, you should probably pay extra close attention. This is one of the invasive plants that supergenes have brought to Norway.

DNA from European species is being collected in an open reference work. Norway’s contributions are well underway.
How animals and plants adapt to the environment is often particularly evident on islands. Now Darwin’s giant daisies are helping researchers understand a little more about how these plants actually go about adapting.
DNA from sticklebacks that is thousands of years old could provide answers to one of the great questions of evolution. The EU is supporting the research with over 600.000 euros.
Ocean-dwelling dolphins have repeatedly adapted to life in coastal areas throughout history.
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.
The story of what happened when a molecular biologist, some engineers and PhDs and postdocs from NTNU and St Olavs Hospital put their heads together to design a completely different kind of coronavirus test.
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.
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.
Norway’s Ministry of Health and Care Services confirmed Friday that it will roll out coronavirus test kits developed by researchers from NTNU and St Olavs Hospital by the last week of April/early May. The kits will more than triple Norway’s testing capacity during the rollout.
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.
Why does the egg size of house sparrows vary so much? Isn’t it always an advantage to be big?
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?
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.
The fungus kills frogs, toads and salamanders, and now we know where it emerged. The pet trade may be to blame.
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.
Should we reintroduce animal species that have died out? New technology may offer opportunities that no one could imagine a few decades ago. But the answer may not be as simple as you think.
The passenger pigeon was once among the most numerous species on earth. The last passenger pigeon died in the Cinncinati Zoo just over 100 years ago. How did it all go so wrong?
The NTNU University Museum’s animal collection is approaching a landmark one million specimens. We take a peek behind the scenes.
A group of researchers spent twelve seasons making some house sparrows bigger and others smaller. Their experiment yielded some important answers.
The relationship children have with their parents can sometimes influence the relationship they have with their teachers. Now we know more about why.
Why do some sparrows hatch six chicks while others don’t hatch any? How does upbringing affect the remainder of their lives? Physiological stress in the nest can actually affect birds’ DNA and possibly their lifespan.
Did some of our human features evolve while our ancestors were living in water? The aquatic ape theory has been disregarded by paleoanthropologists, but it deserves another chance.
Bird songs have many functions, but their main purpose is to attract a mate. Some of the best avian singers are described below.
