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

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

China’s planted forests are growing faster than natural forests

,
A study of China's planted forests reveals faster leaf area expansion driven by younger trees and stronger CO₂ responses, but the advantage may not last

In the Amazon, diseases follow forest transformation

,
A Brazilian study of more than one million cases of malaria, dengue, Chagas disease and leishmaniasis reveals how diseases cluster in distinct “health landscapes” shaped by different land-use: from forest communities to large-scale agricultural systems

New database reveals the climate cost of degradation in tropical forests

,
Researchers have synthesized nearly four decades of data, producing one of the most comprehensive assessments ever compiled of forest carbon dynamics following disturbances and during subsequent regeneration

When El Niño-related drought strikes, Amazon forest turns to chemical self-defense

A study shows how the rainforest altered its volatile compound emissions during the most severe drought ever recorded in the Amazon, triggering a mechanism with implications for the atmosphere

In California, the most devastating wildfires are the new normal

Uno studio mostra come il cambiamento climatico e la gestione delle foreste abbiano trasformato la natura prevalente degli incendi. Dal 2012 sono più comuni i roghi ad alta intensità, con conseguenze ambientali ed economiche sempre più gravi

Palm, coconut and soybean oil account for 1.5 per cent of global biodiversity loss

, ,
A new study reveals that these three oil crops alone are responsible for around 75% of the biodiversity loss linked to agricultural expansion. A consequence of growing demand for many everyday products
Planting trees on pastures is an effective strategy for protecting biodiversity, but not as much as preserving natural forests. Photo: Onderwijsgek Attribution-ShareAlike 3.0 Unported CC BY-SA 3.0 DeedOnderwijsgek Attribution-ShareAlike 3.0 Unported CC BY-SA 3.0 Deed

Planting trees in pastures increases biodiversity by 44 per cent

,
In developing countries, livestock farming is a means of livelihood for one billion farmers, but the growing need for space for pastures is driving deforestation. A German study suggests how to reconcile economic development and biodiversity
