Hanne De Kort, Auteur ; Joachim Mergeay, Auteur ; Kristine Vander Mijnsbrugge, Auteur ; Guillaume Decocq, Auteur ; Simona Maccherini, Auteur ; Hans Henrik Kehlet Bruun, Auteur ; Olivier Honnay, Auteur ; Katrien Vandepitte, Auteur1. Delineation of seed zones or provenance regions to preserve local adaptation is a common practice in forestry and restoration, as locally adapted plants generally possess relatively high levels of productivity and resistance. Provenance trial[...]
Article
Hans Jacquemyn, Auteur ; Rein Brys, Auteur ; Olivier Honnay, Auteur ; Michael J. Hutchings, Auteur1. This account presents information on all aspects of the biology of Orchis mascula (L.) L. (early purple orchid) relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the framework of the [...]
Article
Kitessa Hundera, Auteur ; Raf Aerts, Auteur ; Matthias De Beenhouwer, Auteur ; Koen Van Overtveld, Auteur ; Kenny Helsen, Auteur ; Bart Muys, Auteur ; Olivier Honnay, AuteurThe moist evergreen Afromontane forest of SW Ethiopia has become extremely fragmented and most of the remnants are intensively managed for cultivation of coffee (Coffee arabica), with considerable impacts on forest structure, biodiversity and ec[...]
Article
Kris Van Looy, Auteur ; Hans Jacquemyn, Auteur ; Peter Breyne, Auteur ; Olivier Honnay, AuteurRiver regulation results in the disconnection and increased fragmentation of habitats in the river corridor. In this study, we investigated the within-population genetic variability and among-population genetic differentiation of 21 populations [...]
Article
Hans Jacquemyn, Auteur ; Katrien Vandepitte, Auteur ; Rein Brys, Auteur ; Olivier Honnay, Auteur ; Isabel Roldan-Ruiz, AuteurIn much of Western Europe, orchid species have suffered dramatic declines in abundance, whereas the remaining populations often tend to be small and isolated, occur in ecologically marginal habitats and may show decreased reproductive output due[...]
Article
Hans Jacquemyn, Auteur ; Carmen Van Mechelen, Auteur ; Rein Brys, Auteur ; Olivier Honnay, AuteurCalcareous grasslands, most of which are man made and therefore depend on some kind of human interference for their maintenance, are among the most species-rich communities on Earth at a small scale. For many centuries, most of these grasslands [...]
Article
Dries Adriaens, Auteur ; Olivier Honnay, Auteur ; Martin Hermy, AuteurLong transient times in response to decreasing habitat area and increasing isolation may cause the present plant species distribution to reflect the historical rather than the present landscape configuration, resulting in a so-called extinction [...]
Article
Hans Jacquemyn, Auteur ; Olivier Honnay, Auteur ; Thierry Pailler, AuteurTropical oceanic islands contribute disproportion ably for their area to global biodiversity and this is especially true for islands with strong altitudinal gradients. On these islands, species richness and composition usually change with altitu[...]
Article
Olivier Honnay, Auteur ; Hans Jacquemyn, Auteur ; Kris Van Looy, Auteur ; Katrien Vandepitte, Auteur ; Peter Breyne, Auteur1. Metapopulation dynamics - the recurrent extinction and colonization in spatially discrete habitats - is expected to strongly affect within and between population genetic diversity. So far, however, accounts of true plant metapopulations are e[...]
Article
Tobias Ceulemans, Auteur ; Roeland Merckx, Auteur ; Maarten Hens, Auteur ; Olivier Honnay, Auteur1. Both nitrogen (N) and phosphorus (P) enrichment have been identified to drive plant species losses from nutrient-poor semi-natural grasslands. The relative contribution of N vs. P to species loss remains unclear, however. 2. We investigated h[...]
