Journal ArticleDOI
Extinction debt of forest plants persists for more than a century following habitat fragmentation.
Mark Vellend,Kris Verheyen,Hans Jacquemyn,Annette Kolb,Hans Van Calster,George Peterken,Martin Hermy +6 more
TL;DR: The ability of the Lincolnshire models to predict patch occupancy in Vlaams-Brabant was worse for slow than for fast species, indicating that more than a century after forest fragmentation reached its current level an extinction debt persists for species with low rates of population turnover.
Journal ArticleDOI
Susceptibility of Common and Rare Plant Species to the Genetic Consequences of Habitat Fragmentation
Olivier Honnay,Hans Jacquemyn +1 more
TL;DR: It is suggested that many fragmented habitats have become unable to support plant populations that are large enough to maintain a mutation-drift balance and that occupied habitat fragments have become too isolated to allow sufficient gene flow to enable replenishment of lost alleles.
Journal ArticleDOI
Homogenization of forest plant communities and weakening of species–environment relationships via agricultural land use
Mark Vellend,Kris Verheyen,Kathryn M. Flinn,Hans Jacquemyn,Annette Kolb,Hans Van Calster,G. F. Peterken,Bente J. Graae,Jesse Bellemare,Olivier Honnay,Jörg Brunet,Monika Wulf,Fritz Gerhardt,Martin Hermy +13 more
TL;DR: This analysis of data from 1446 sites in ancient and recent forests across 11 different landscapes in north-eastern North America and Europe shows decreases in beta diversity and in the strength of species‐environment relationships in recent vs. ancient forests.
Journal ArticleDOI
Forest fragmentation effects on patch occupancy and population viability of herbaceous plant species
TL;DR: This review discusses extinction and colonization dynamics of forest plant species at the regional scale and suggests that the use of the metapopulation concept, both because of its heuristic power and conservation applications, may be fruitful.
Journal ArticleDOI
Possible effects of habitat fragmentation and climate change on the range of forest plant species
TL;DR: In this article, the authors report the results of two forest plant colonization studies in two fragmented landscapes in central Belgium and show that almost all forest plant species (85%) had an extremely low success of colonizing spatially segregated new suitable forest habitats after c. 40 years.
