Travelling with the family may also be a good time to read this book. Here in the Camargue Biosphere Reserve (France), a biogeographical hub for ecological communities in Europe. Photo credit: Borja Jiménez-Alfaro

In the last years, I have been looking at different views for understanding the spatial patterns of plant communities.…

Planned Special Feature of JVS: Dispersal and establishment as drivers of vegetation dynamics and resilience

Guest editors: Péter Török, James Bullock, Borja Jiménez-Alfaro, Judit Sonkoly

Background
Plant regeneration plays a decisive role in vegetation dynamics by underpinning local and landscape-scale processes, biodiversity patterns, and community resilience to abiotic and anthropogenic disturbances. As establishment and recruitment depend greatly on spatial plant dispersal and the local propagule bank, studying their contributions to these processes is crucial.…

Which results of the standard test for community weighted mean approach are too optimistic?

David Zelený

The relationship between the average height of understory herbs (CWM of species height) and the amount of light passing through the forest canopy (quantified by visually estimated cover of trees and shrubs at each site). If the analysis based on CWM approach was done by a standard parametric test, the result is highly significant (P<0.001). However, the result of the standard test is overly optimistic; the max test, which is the correct test for this analysis, returns considerably less exciting P-value (P=0.052).

Imagine a forest, with trees forming a canopy and herbs growing in the understory.…
