摘要: Question: We hypothesised that, even within the same plant functional group, there are specific distributions in land-cover classes and with change that associated niche breadth rather than reproductive strategy, broader of species better they cope different changes over time. Location: The Llobregat Delta (Barcelona, Spain). Methods: analysed distribution pattern eight coexisting wetland perennial monocotyledons human disturbance (obtained from classification categories relation to their level disturbance) such 1956 1999. then compared regional abundance patterns seed dispersal type (wind dispersed versus non-wind species), vegetative spread (tussock caespitose-running (the number phytosociological alliances which each is found). Results: Regional was positively related breadth, but independent traits. Similarly, were In general, more specialist species, (i) concentrated natural habitats, (ii) less able with, (iii) restricted stable types, particularly longstanding areas. Conclusions: Ecological plasticity capacity dominant determines ability recent future Mediterranean wetlands. As habitat specialists resistant landscape generalists, floristic homogenisation may progress these habitats likely scenario increasing turnover.
