Heat and land use: Bees suffer in particular
Heat and land use: Bees suffer in particular
In a new study, researchers at the University of Würzburg are investigating the interaction of major global change drivers on insects. The number and diversity of insects is declining worldwide. Some studies suggest that their biomass has almost halved since the 1970s. Among the main reasons for this are habitat loss - for example through agriculture or urbanization - and climate change.

Internal Clocks Determine the Ups and Downs of Antarctic Krill
Internal Clocks Determine the Ups and Downs of Antarctic Krill
The behavior of Antarctic krill not only reacts to external environmental influences such as light or food. It also uses its internal clock to adapt to the extreme conditions of the polar environment. Individually, Antarctic krill ( Euphausia superba ) do not make much of an impression. With a maximum body length of six centimetres, a weight of just two grams and its transparent skin, it does not look very spectacular.

New Method Provides Fresh Insights into Insect Decline
New Method Provides Fresh Insights into Insect Decline
Agriculture's impact on insect diversity is more severe than previously thought, according to a new study from the Julius-Maximilians-Universität Würzburg. It has long been known that agriculture contributes to the decline in insect biodiversity. The loss of host plants, frequent mowing, and pesticide use all deprive many species of their habitats.

More social parrots have a better vocabulary
To the point Complex communication: Researchers studying the social networks of monk parakeets in Spain uncovered a link between an animal-s social ties and the calls that it makes. Levels of sociality: They spent two years recording the social lives, as well as all screeches, squawks and whistles, of over 300 parrots-linking what individuals say to very specific levels of sociality.

Experiment in Leipzig's floodplain forest: Using tree mortality to support oak regeneration
Experiment in Leipzig’s floodplain forest: Using tree mortality to support oak regeneration
The pedunculate oaks typical of Leipzig's floodplain forest and other German oak forests are struggling to regenerate in the understorey due to a lack of light. One reason for this is the absence of flooding in floodplain forests. In a two-year oak experiment in Leipzig's floodplain forest, researchers from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv) found that the current tree dieback - caused by drought and pest outbreaks - combined with the thinning of certain understorey species, can actually support oak regeneration.

Experiment in the riparian forest: tree mortality can be used for oak regeneration
Experiment in the riparian forest: tree mortality can be used for oak regeneration
The English oaks typical of the Leipzig riparian forest and other German oak forests can hardly rejuvenate due to a lack of light in the undergrowth. One reason for this is the lack of flooding in alluvial forests. Researchers from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv) have discovered in a two-year oak experiment in Leipzig's alluvial forest that the current tree mortality as a result of droughts and the spread of pests can be used in combination with a thinning out of certain species in the undergrowth for oak regeneration.

’Internet of nature’ helps researchers explore the web of life
A novel paper led by Ulrich Brose of the Friedrich Schiller University Jena and the German Centre for Integrative Biodiversity Research (iDiv) is widening understanding of how species interact within ecosystems via the so-called ,Internet of Nature'. Published in 'Nature Ecology and Evolution', the paper reveals that species not only exchange matter and energy but also share vital information that influences behaviour, interactions, and ecosystem dynamics - revealing previously hidden characteristics of natural ecosystems.

The cold after egg time
The cold after egg time
Iceberg armadas and altered river courses caused parts of the northern hemisphere to cool rapidly on several occasions Abrupt climate changes: From the peak of the last ice age to the Holocene, the North Atlantic and neighboring regions cooled rapidly again and again, temporarily. Revealing model simulations: Between 20,000 and 13,000 years ago, ice masses breaking off from the ice sheets of the northern hemisphere enriched the North Atlantic with fresh water and weakened the Atlantic overturning circulation (Amoc), which transports heat from the tropics to the north.

Colourful city birds
Colourful city birds
To the point Successful: Birds in the city are less likely to have brown plumage, and those with colorful plumage are more common. Differences between city and countryside: It is usually warmer in cities, there are fewer predators, but there is more artificial light and other background colors Advantages: Camouflage is not as important in the city because there are fewer predators than in nature.

Shy mice are more persistent problem-solvers
In a study, it wasn't the bravest mice, but rather the shy ones, that proved to be the most persistent tinkerers To the point More successful: Shy mice visited problem-solving tasks more often than their bold counterparts, giving them more chances to succeed. Testing conditions matter: mice performed differently in natural environments compared to laboratory settings - and not always in predictable ways.
