Small 'snowflakes' in the sea play a big role

In the deep waters that underlie the productive zones of the ocean, there is a constant rain of organic material called "marine snow." Marine snow does not only look like real snow but also behaves similarly: Large flakes ...

How grasslands respond to climate change

"Based on field experiments with increased carbon dioxide concentration, artificial warming, and modified water supply, scientists understand quite well how future climate change will affect grassland vegetation. Such knowledge ...

Fingerprint for the formation of nitrous oxide emissions

Scientists led by Eliza Harris and Michael Bahn from the Institute of Ecology at the University of Innsbruck have succeeded in studying emissions of the greenhouse gas N2O under the influence of environmental impacts in an ...

Large mammals make soil more fertile in tropical forests

The White-lipped peccary (Tayassu pecari) is a boar-like hoofed mammal found throughout Central and South America. These animals roam the forest in bands of 50 to 100 individuals, eating a wide variety of foods. In Brazil's ...

Peatland carbon and nitrogen stocks vulnerable to permafrost thaw

Northern peatlands hold large stocks of carbon and nitrogen and thus play a key role in global climate dynamics. However, their vulnerability to climate warming is uncertain, due in part to a lack of spatially explicit, observation-based ...
