| Popis | Developing a strategy for evidence-based conservation is often problematic where a given habitat is found on relatively few small sites. Here, we investigate the important environmental variables that control species alpha-diversity in wet mesotrophic grasslands in lowland England. We analysed data on species richness and three soils variables from 10 mesotrophic grasslands to test the following hypothesis: is species diversity related to these soil factors, and if so, which is the most important? Generalised linear modelling was used to derive minimum adequate models of these relationships. The analysis identified degree of waterlogging and its interaction with both soil available phosphorus and soil pH as significant. Species diversity decreased with increasing waterlogging and available phosphorus. |
