Just one degree can change a species
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.

The fisheries and aquaculture sectors are major users of plastics. A research project has recently been launched to investigate how these plastics can be recycled and made into new products.
This summer, a coalition of researchers led by the Norwegian University of Science and Technology reported the first-ever use of a fibre-optic cable network to eavesdrop on whales in the Arctic. Now they suggest these networks be used to establish a low-cost global ocean-earth observatory.
Artificial intelligence can be of great benefit underwater and SINTEF, in collaboration with the research centre SFI Exposed, is developing systems that will help to boost fish farm safety and security under harsh sea conditions.
Cattle farming has often been portrayed as having the most detrimental environmental impact because it takes the most grazing land, uses a lot of water and has large methane emissions. But it’s not the worst. And is locally produced food always best for the environment?
The Arctic Pearl is setting course for the Barents Sea in search of the shellfish delicacy Iceland scallop. It is the first and only vessel of its kind, crammed with new technology that may herald the start of a new era in bottom fishing.
DNA from European species is being collected in an open reference work. Norway’s contributions are well underway.
Australia has a seafloor monitoring program where they can precisely surveil the changes in the environment. NTNU has attracted one of the key researchers from this project. Oscar Pizarro’s research goal is to find tools to facilitate continuous observation with less resources.
Lena van Giesen, an associate professor at NTNU’s Department of Biology, was awarded EUR 1.7 million by the European Research Council (ERC) to study larval development of the coral Lophelia pertusa as well as its environment.
What are people’s attitudes towards food, sustainability, new foods and food additives? Researchers have found some answers.
We know very little about very many species. Unfortunately, that’s often not a good sign.
Researchers have succeeded in showing that mackerel turn blue when under stress. This new knowledge will better enable our fisheries to safeguard fish welfare and will optimise catch quality into the bargain.
Which organisms survive and which succumb when the climate changes? A small larval fish is providing surprising insight into how the brain reacts when the temperature rises.
Is it too late to save our planet? Professor Jianguo Liu is the newest winner of The Gunnerus Award in Sustainability Science. He offers us some hope.
Researchers had the crazy idea of feeding ragworms with locally-cultivated seaweeds. The results were as gold-edged as the worms themselves – a high-quality, locally-sourced and sustainable feed for farmed salmon.
NTNU biology and cybernetics researchers have built a robot that allows them to sample everything from microplastic to salmon lice densities.
Researchers at NINA, the Norwegian Institute for Nature Research, and NTNU have developed a new method for monitoring salmon lice larvae along the coast. The lice trap is now being tested in the Hardangerfjord.
At the boundary between the land and sea, there exists an ecosystem that has been overlooked by Norwegians for so long that it was only recently given an official name. But studies are revealing that it has some very desirable properties.
The Earth’s oceans are crisscrossed with roughly 1.2 million km of fibre optic telecommunication cables — enough to girdle the planet 30 times. Researchers have now succeeded in using fibre in a submarine cable as a passive listening system, enabling them to listen to and monitor whales.
When hydroelectric power plants suddenly switch off the water, we risk killing fish fry and other living organisms in rivers. The regulations need to change, say scientists and anglers.
When salmon ingest parasites, the parasite may not be the only factor that determines the impact on the health of the fish.
NTNU researchers from AMOS, the Centre for Autonomous Marine Operations and Systems, used small satellites and subsea robots — and everything in between — to study marine life in Svalbard’s Kongsfjorden in a first-ever experiment in May.
Using non-recyclable plastic waste as an alternative to coal may prevent huge volumes of plastic from being discarded into the oceans – and will also reduce CO2 emissions. This is the conclusion of a recently completed pilot project headed by SINTEF in Vietnam.
An animal’s ability to adapt to its environment is clearly key to its survival, but does that ability come at a physiological cost? A clever experiment with laboratory zebrafish and their wild relatives suggests it does.
