This paper aims to assess the relative importance of the type of built-up area in structuring plant species composition and richness in urbanised environments. The study was carried out in the city of Brussels where all vascular plant species were recorded in 189 grid cells of 1 km2 each. The effect of urban land use type on species composition was(More)
In this study we analyzed patterns of native and exotic species richness in the urban flora of Brussels (Belgium) using a coarse-scale systematic sampling grid of 1 km2. The observed correlation between native and exotic richness within the grid cells sampled was then compared to the results of an adequate null model assuming no species interactions. In(More)
Facing the current biodiversity crisis, the value of ex situ conservation has been increasingly acknowledged in international treaties and legislations. Seed banks are a good way of conserving biodiversity, providing that seeds are of high quality and at maximum viability. However, despite the number of established ex situ facilities, there is little(More)
Recently, dated phylogenies have been increasingly used for ecological studies on community structure and conservation planning. There is, however, a major impediment to a systematic application of phylogenetic methods in ecology: reliable phylogenies with time-calibrated branch lengths are lacking for a large number of taxonomic groups and this condition(More)
A floristic survey has been carried out in a peri-urban forest, the Sonian Forest in Brussels, to identify indicator plant species in the herbaceous layer, which could be used as an aid within the framework of a more sustainable management of the forest. Three hundred and seventy two (372) taxa have been identified, 33 of which are non-native (i.e.(More)
Increasing globalization and human mobility have facilitated the intentional and unintentional introduction of species beyond their natural geographic ranges. Such alien species are considered to be a main driver of global biodiversity loss with substantial environmental and economic impacts on invaded communities. While the potential economic cost for(More)
This paper describes the ground floor vegetation that developed four years after tillage implements in an ancient beech forest in central Belgium. The purpose of this study was twofold: (1) to explore whether tillage has a lasting effect on soil compaction and soil moisture as well as on vegetation characteristics; and (2) to analyse whether two distinct(More)
Plant reintroductions include labor-intensive, costly, and time-consuming work and often cannot guarantee a successful outcome. In order to maximize the chances of success, it is therefore of utmost importance to appropriately select target species, release site, cultivation and reintroduction methodology, and management technique of the out-planting site.(More)
In a 4383 ha beech forest in central Belgium, we investigated whether, within clearcuts, microclimate gradients are detectable, and we tested for correlations between plant species composition and microclimatic heterogeneity. The results highlight a strong correlation between microclimatic parameters and distance from the forest edge. Of the 47 taxa found,(More)
Seed development, dormancy and germination of the American invasive tree species, Prunus serotina, are described for plants growing in a large forest in Belgium. Seeds of P. serotina were collected following anthesis in the first week of July and thereafter at fortnightly intervals. Seed dormancy, temperature requirements for germination and the soil seed(More)
