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.

The story of the cooking pits of yore has made one archaeologist feel – at least a litte bit – like Indiana Jones.
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.
Every now and then, researchers are lucky enough to experience a Eureka moment — when a series of facts suddenly crystallize into a an entirely new pattern. That’s exactly what happened to Birgit Maixner from the NTNU University Museum when she began looking at artefacts and place names.
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.
Two people died roughly 100 years apart. Nevertheless, they were buried together. In boats.
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.
“A very rare and exciting find,” says NTNU University Museum archaeologist Raymond Sauvage.
“Vessels like these were imported from the Roman Empire and confirm that this was an area of status and wealth during Roman times,” says archaeologist Merete Moe Henriksen.
Regular protective treatment of rock carvings and paintings has done a good job protecting this important part of Norway’s cultural heritage. But according to the current schedule, the unique programme will end next year.
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.
