Retention forestry implies that biological legacies like dead and living trees are deliberately selected retained beyond harvesting cycles to benefit biodiversity ecosystem functioning. This model has been applied for several decades in even-aged, clearcutting (CC) systems but less so uneven-aged, continuous-cover (CCF). We provide an overview of retention CCF temperate regions Europe, currently largely focused on habitat wood. The relevance current meta-analyses many other studies CC is...

Abstract One of the most important drivers for coexistence plant species is resource heterogeneity a certain environment, and several studies in different ecosystems have supported this heterogeneity–diversity hypothesis. However, to date, only few measured light soil resources below forest canopies investigate their influence on understory richness. Here, we aim determine (1) stand structural complexity canopy (2) whether increases Measures were obtained through inventories remote sensing...

Abstract Managed forests are a key component of strategies aimed at tackling the climate and biodiversity crises. Tapping this potential requires better understanding complex, simultaneous effects forest management on biodiversity, carbon stocks productivity. Here, we used data 135 one-hectare plots from southwestern Germany to disentangle relative influence gradients intensity, productivity different components (birds, bats, insects, plants) tree-related microhabitats. We tested whether...

Abstract Managing forests to sustain their diversity and functioning is a major challenge in changing world. Despite the key role of understory vegetation driving forest biodiversity, regeneration functioning, few studies address functional dimensions response silvicultural management. We assessed influence regimes on redundancy European understory. gathered vascular plant abundance data from more than 2000 plots forests, each associated with one out five most widespread regimes. used...

1. How herbivore plant diversity relationships are shaped by the interplay of biotic and abiotic environmental variables is only partly understood. For instance, commonly assumed to determine abundance richness associated specialist herbivores. However, this relationship can be altered when such as temperature covary with diversity. 2. Using gall‐inducing arthropods focal organisms, were tested for their relevance herbivores host plants. In particular, hypothesis that increase was addressed....
