In temperate latitudes, the circadian clock of the fruit fly follows a clear rhythm. Animals that live near the poles in contrast exhibit a highly arrhythmic behaviour.

Circadian clocks coordinate the organism to the alternating cycles of day and night. Scientists from the University of Würzburg have studied how these clocks work in polar regions where days or nights can last for weeks.

Radar can be used to survey the diversity of species in forests. The picture shows a complex mixed mountain forest.

With freely available radar data from satellites, biodiversity in forests can be analysed very well. In Nature Communications, researchers report that biodiversity even of tiny insects can be reliably modelled from space.

A pantaloon bee with pollen baskets visiting blue weed: multiple bee species contribute to pollination services in agricultural landscapes.

Around 20 percent of the world's agricultural areas yields less than it did 20 years ago. According to the Food and Agriculture Organization FAO, humans are the culprit: we have not done enough to protect biodiversity.

Pflanzen schützen sich vor Pilzen und anderen Krankheitserregern (Pathogenen), indem sie ihre Stomata verschließen.

Using special receptors, plants recognize when they are at risk of fungal infection. This new finding could help cultivate resistant crops and reduce pesticide usage.

Spruces killed by bark beetles in the Bavarian Forest National Park

Removing dead trees from the forests and reforesting on a large scale: this is the German Federal Government's strategy against "Forest Dieback 2.0". Ecologists from the University of Würzburg call for other solutions.
