Otoliths - the fish’s black box - also keeps an eye on the metabolism

For the first time ever, an international research team has shown that fish otoliths record information on fish metabolism. Analyses of old and new otoliths can therefore provide new knowledge about how different species of fish adapt to new conditions, including climate change.

Satellite images reveal global poverty

How far have we come in achieving the UN’s sustainable development goals that we are committed to nationally and internationally? Yes, it can be difficult to make a global assessment of poverty and poor economic conditions, but with an eye in the sky, researchers are able to give us a very good hint of the living conditions of populations in the…

Conference: Partnerships for a sustainable future

Join us when Aarhus University invites to a conference about UN's 17 sustainable development goals, focusing on developing sustainable solutions in collaboration between the university, public authorities and companies.

When porpoises are caught in seine nets, scientists are able to catch the animal alive and attach transmitters to their backs before they are released again. Photo: Jonas Teilmann

A blubber coat and large amounts of fish keep Denmark’s smallest whale, the porpoise, alive in the cold winter

Porpoises are among the world’s smallest marine mammals, but despite their small size they need to maintain a body temperature of 37 degrees year-round, just like all other mammals. We, land-living mammals, would soon succumb to the ice-cold water where the temperature gets down to zero degrees in winter. How do the porpoises meet the challenge?

A bigger nose, a bigger bang: size matters for echolocating toothed whales

Whales, dolphins, and porpoises have all evolved to use similar narrow beams of high intensity sound to echolocate prey. Far from being inefficient, this highly focused sense may have helped them succeed as top predators in the world's oceans.

Fewer females cause ripples in the duck pond

A new study from the Department of Bioscience shows a surprising decrease in the proportion of females among four common waterfowl. Researchers are concerned about the uneven gender balance and predict it could have consequences for the populations, if the trend continues.

Mentor scheme ensures new students a good start at Bioscience

The Department of Bioscience tested a mentor scheme the previous semester, where a team of older students guided students at the second semester about life as a biology student. The evaluations were very positive, and the arrangement is repeated in the spring. Here four students talk about what they got out of participating.

Mammals cannot evolve fast enough to escape current extinction crisis

We humans are exterminating animal and plant species so quickly that nature's built-in defence mechanism, evolution, cannot keep up. An Aarhus-led research team calculated that if current conservation efforts are not improved, so many mammal species will become extinct during the next five decades that nature will need 3-5 million years to…

Associate Professor Hans Røy gave a presentation about his collaboration with Dong Energy Oil & Gas.
Both researchers and students participated in the networking and career day.
Researchers and representatives from the business community queued up to give a one-minute madness-presentation to the other participants.
After some inspiring presentations, the participants were able to network at the stands or over a bite of tapas.
