Europe’s forests: why we need to measure their resilience

,
Le raccomandazioni di eLTER: Superficie e biomassa non bastano più a definire la capacità di ripresa delle foreste. Necessari nuovi indicatori, osservazioni di lungo periodo e modelli capaci di anticipare i rischi

AI uses a pigment to reveal the condition of biocrusts

For the first time, researchers have remotely measured the concentration of scytonemin, an indicator of the development and resilience of biocrusts in arid ecosystems

Heat and drought: natural forests resist better, planted forests recover faster

,
A Yangtze Basin study reveals a trade-off between resistance and recovery in forests: biodiversity and structure protect natural forests, while young, fast-growing trees promote recovery in planted forests

Extreme drought: biodiversity helps grasslands, but not forests

,
An international study finds that high biodiversity levels can reduce productivity losses in the driest grasslands during extreme drought events. However, the same pattern is not found in forested areas

Insects, food production and biodiversity thrive together through agriwilding

Productive crops, trees, species-rich grasslands and natural succession: agriwilding, a Belgian study explains, encourages the return of pollinators and opens new prospects for more sustainable agriculture
