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.
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.
Sea trout populations have declined sharply. Researchers have studied the life of sea trout by means of acoustic telemetry tags and listening stations. Now they know more about what we need to do to protect the sea trout population.
Bushfires are a normal part of the cycle of nature in Australia. But not like this. And it is going to get worse.
Moose prefer to browse on deciduous trees. Then conifers take over and affect the species diversity in the forest. One researcher contends that Norwegian wildlife management is not good enough to address what happens in the wake of these large herbivores.
A newer method of measurement has helped scientists date some stave churches more accurately than in the past. The method shows that several stave churches are older than the dates previously attributed to them.
We can’t take care of the Earth’s species unless we know what species exist. A collaborative project that will help us know more is being launched in Trondheim during The Big Challenge science festival.
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.
