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.

Enzymes from bacteria and fungi break down plastic
Plastic is useful but also poses an environmental problem. Scientists are now using enzymes from bacteria and fungi to break down plastic.
Eavesdropping on the Earth itself
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.
World’s food production footprint on climate and environment
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?
Goal is to add 15 000 species to the DNA library in Europe
DNA from European species is being collected in an open reference work. Norway’s contributions are well underway.
More efficient ocean mapping and monitoring
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.
ERC support for coral research
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.
Half of the data deficient species may be threatened with extinction
We know very little about very many species. Unfortunately, that’s often not a good sign.
It is not enough to save water – we must reuse it
Is it safe to use treated wastewater to irrigate lawns and vegetable crops? This is the question now being addressed by researchers and the water industry.
What goes on in the brain when it gets too hot?
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.
How a plant from the USA invaded Europe
This invader can extend the pollen season to November, and it is heading towards Norway. For now, it has stopped in Denmark.
Arctic mercury levels drop during the depths of the winter
The interplay between mercury and manganese in Arctic seawater may explain a surprising drop researchers found in mercury levels in the Barents Sea during the winter.
Darwin’s giant daisies and evolution
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.
Twin mothers aren’t more fertile – just luckier
The prevailing belief by researchers has been that mothers of twins are more fertile than other women. But a new study shows that isn’t the case.
“Pamela” makes studying the ocean easy and affordable
NTNU biology and cybernetics researchers have built a robot that allows them to sample everything from microplastic to salmon lice densities.
Testing lice traps on the Hardanger coast
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.
Eavesdropping on whales in the high Arctic
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.
Norwegian rivers need to be better protected
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.
Parasites affect salmon in several ways
When salmon ingest parasites, the parasite may not be the only factor that determines the impact on the health of the fish.
Observing Arctic marine life — from the seabed to space
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.
A cushy lab life has its evolutionary costs — when it comes to fish, that is
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.
The Detectives: Hunting toxic chemicals in the Arctic
What researchers are learning about the fate of chemicals in the Arctic, and how what they’re learning is changing international law and providing life-saving advice.
Two Industrial Ecology professors named to international climate-related posts
Professor Edgar Hertwich has been named to the EU’s newly constituted European Scientific Advisory Board on Climate Change, while Professor Francesco Cherubini has been asked to serve as a Lead Author for an upcoming assessment by The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).
ERC Grant aims to figure out the cost of survival
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.
