Finding old — and hardy — apple varieties was a challenge for the Trøndelag apple community.
We think of trees as silent sentinels, watching as the world goes by and the ages pass. But what if you could interview them about what they have seen?
The number of lemmings varies greatly from year to year. Other species also have similar fluctuations. Why is it like this, and what happens if lemming years happen less often?
Approximately 47 000 different species have been identified in Norway – and there are probably many more. A new tool can help us gain a better overview.
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.
Climate researchers have long known that large animals, like moose, could play a role in how much the Earth will warm due to climate change. But the question is, how much? New research shows the answer can be a lot.
You don’t get to discover a new insects and arachnids numbering in the hundreds every day. Most of the new discoveries were of the biting midge variety.
Even seemingly small changes in the climate can change the number of animals and plants in an area and how species behave, new research shows. Natural history collections provide valuable insights.
DNA from European species is being collected in an open reference work. Norway’s contributions are well underway.
This invader can extend the pollen season to November, and it is heading towards Norway. For now, it has stopped in Denmark.
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.
When salmon ingest parasites, the parasite may not be the only factor that determines the impact on the health of the fish.
Ladybird beetles are probably among the most popular insects we have. Did you know that Norway has some 50 different species – plus some unwelcome guests?
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.
With the warming climate, forests are growing faster than before, and deciduous species are growing the fastest. Recent research illustrates just how much moose foraging limits this growth.
All over the world, people are moving out of rural areas, and cities are growing. What will be the impact on resident species that live in these cities? Which will be our new plant and animal neighbours, which will have to leave town, and what does that mean for us humans?
The new species of nudibranch, Dendronotus yrjargul, is named after the municipality where it was found.
Sea trout numbers are declining in Norway and scientists don’t know why. They have studied the trout in two rivers in northern Norway’s Nordland county. Soon, sea trout along the entire Norwegian coast will be investigated.
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.
