Global impoverishment of natural vegetation revealed by dark diversity

Meelis Pärtel, Riin Tamme, Carlos Perez Carmona, Kersti Riibak et autres

. In the sampled regions with a minimal human footprint index, an average of 35% of suitable plant species were present locally, compared with less than 20% in highly affected regions. Besides having the potential to uncover overlooked threats to biodiversity, dark …

Endozoochorous plant dispersal by the Brown Bear ( Ursus arctos ) in the Pyrénées: angiosperms but also ferns and mosses and the importance of disaggregation agents

Grégoire Pauly, Cécile Vanpé, Mélanie Roy, Pierre‐Yves Quenette et autres

Endozoochory by megafauna enables temperate mountain plants to disperse over long distance. As an endozoochorous agent, Brown Bear may play a unique role through its biology and ecology especially because of its diverse diet (angiosperms, ferns, mosses). However, few studies have been …

Can vegetation clearing operations and reprofiling of bars be considered as an ecological restoration measure? Lessons from a 10‐year vegetation monitoring program (Loire River, France)

Philippe Janssen, Richard Chevalier, Michel Chantereau, Rémi Dupré et autres

Maintenance operations in regulated rivers are often implemented as preventive measure to maintain wide, smooth channels and to limit the risk of flooding. By clearing vegetation, removing roots and lowering sediment bar elevation, these works can recreate pioneer habitats and related plant …

Effects of stand structure and ungulates on understory vegetation in managed and unmanaged forests

Laura Chevaux, Anders Mårell, Christophe Baltzinger, Vincent Boulanger et autres

Conventional conservation policies in Europe notably rely on the passive restoration of natural forest dynamics by setting aside forest areas to preserve forest biodiversity. However, since forest reserves cover only a small proportion of the territory, conservation policies also require complementary conservation …

The climatic debt is growing in the understorey of temperate forests: Stand characteristics matter

Benoît Richard, Jean‐Luc Dupouey, Emmanuel Corcket, Didier Alard et autres

Abstract Aim Climate warming reshuffles biological assemblages towards less cold‐adapted but more warm‐adapted species, a process coined thermophilization. However, the velocity at which this process is happening generally lags behind the velocity of climate change, generating a climatic debt the temporal dynamics …

The closer the better? Relative influence of forest continuity and distance to water on the taxonomic and functional structure of riparian plant communities along headwater streams

Philippe Janssen, Richard Chevalier, André Évette, Frédéric Archaux

Abstract Questions (a) Is forest temporal continuity an important factor in structuring the riparian plant communities along small alluvial valleys? (b) To what extent can distance from the stream modulate the effect of forest continuity and provide a better understanding of the …
