Forest biodiversity benefits from warmer microclimate, but only in colder regions

The study shows that warmer microclimates in forest gaps boost biodiversity in colder regions but not in warmer ones, suggesting climate-specific forest management strategies.

Enhancing structural heterogeneity in managed forest landscapes promotes gamma but not beta diversity in understorey plant communities

This study shows that increasing structural heterogeneity in managed forests boosts gamma diversity in understorey plants but not beta diversity, with light niche variation playing a key role.

Advancing the quantification of land-use intensity in forests: the ForMIX index combining tree species composition, tree removal, deadwood availability, and stand maturity

The paper introduces ForMIX, a new index to quantify land-use intensity in forests using tree species composition, tree removal, deadwood availability, and stand maturity, and demonstrates its effectiveness across different forest types.

Forest vertical and horizontal temperature similarity drives arthropod communities in a managed temperate forest

The paper examines how vertical and horizontal temperature differences in a managed forest influence arthropod communities using temperature loggers and metabarcoding.

Microclimatic heterogeneity is associated with forest structural complexity and biodiversity

The paper quantifies microclimatic heterogeneity in forests and links it to biodiversity, showing that canopy structure and gaps influence temperature variation and species diversity.

Isohydric species show earlier drought-induced declines in stem water content, rehydration, sap flow, and growth than anisohydric species

This study compares drought responses between isohydric and anisohydric tree species, finding isohydric species experience earlier declines in stem water content, sap flow, and growth than anisohydric species during soil dry-down.

Inconsistent short-term effects of enhanced structural complexity on soil microbial properties across German forests

This study examines how enhancing structural complexity in German forests affects soil microbial properties, finding site-specific effects influenced by soil moisture and understorey vegetation.

One to rule them all? Assessing the performance of sustainable forest management indicators against multitaxonomic data for biodiversity conservation

The paper evaluates Forest Europe biodiversity indicators against multitaxonomic data, finding no single indicator captures overall biodiversity, but combinations perform better.
