Depending on the variability of precipitation in the Mediterranean zone, ephemeral species vary considerably from year to year. My study examined whether the occurrence of ephemeral wetland vegetation in Mediterranean heathland and maquis (shrubland) communities is associated with certain scrub types. I also investigated whether the cover of dwarf rush communities can be quantified by dependence on topographic parameters on a landscape scale. The study area, chosen as a typical heath-maquis example, lies in Southern Spain. I analyzed the vegetation complexes using classification by floristic similarity and indirect and direct ordination techniques. Habitat suitability modelling was made using generalized linear models. The results show that ephemeral wetland vegetation was associated with maquis communities dominated by Pistacia lentiscus. Atlantic heathlands did not co-occur with ephemeral wetlands. Ephemeral wetland species were rare in scrub communities on clayey soils. The cover of ephemeral wetland vegetation in shallow depressions could be well predicted with topographic variables at a 10 m×10 m resolution. The inclusion of soil moisture, a variable only available for the sampling sites, enhanced model predictions remarkably. Modelling of the cover of ephemeral wetlands is crucial for the consideration of these communities in conservation planning.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Martinez-Ruiz, C.</style></author><author><style face="normal" font="default" size="100%">Marrs, R.

Location: Central-western Spain. Methods: We monitored successions on three waste materials left after uranium mining: unbroken waste, broken waste and wastes amended with a sandy material (Arkoses); both north and south aspects were also studied on each substrate. Results: The substrate starting quality had the greatest influence on spontaneous succession, separating the poorer quality substrates (broken and unbroken wastes) from the better ones (Arkoses) and two reference communities (Topsoil and Dehesa). The importance of aspect was confirmed then within each substrate type. Most species with a short life span (mostly annuals and a few biennials), together with some woody species on Arkoses, showed no response to age (years following the deposition of new soil). Others short-lived species declined over time on the poorer wastes but not on the better Arkoses. There was a tendency for life form replacement (from therophytes to hemicryptophytes) during succession only on the poorer-quality substrates. No dispersal-mode replacement sequence was found. Conclusion: Improving the abiotic conditions of the substrate had a great effect on vegetation succession, but this effect was modified by aspect. Aspect took longer to induce differences in floristic composition on the poorer substrates, where succession was slower. Some trends in species responses to successional change were found by considering species traits, particularly life-form.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: GAMLA VAGEN 40, S-770 13 GRANGARDE, SWEDEN&lt;br/&gt;publisher: OPULUS PRESS UPPSALA AB</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Martinez-Ruiz, C</style></author><author><style face="normal" font="default" size="100%">Marrs, R H</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Some factors affecting successional change on uranium mine wastes: Insights for ecological restoration</style></title><secondary-title><style face="normal" font="default" size="100%">APPLIED VEGETATION SCIENCE</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">aspect</style></keyword><keyword><style  face="normal" font="default" size="100%">correspondence analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">forward selection</style></keyword><keyword><style  face="normal" font="default" size="100%">HOF modelling</style></keyword><keyword><style  face="normal" font="default" size="100%">species trait</style></keyword><keyword><style  face="normal" font="default" size="100%">substrate</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year></dates><publisher><style face="normal" font="default" size="100%">OPULUS PRESS UPPSALA AB</style></publisher><pub-location><style face="normal" font="default" size="100%">GAMLA VAGEN 40, S-770 13 GRANGARDE, SWEDEN</style></pub-location><volume><style face="normal" font="default" size="100%">10</style></volume><pages><style face="normal" font="default" size="100%">333--U25</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Question: Are growth form and dispersal-mode replacement during vegetation succession in semi-arid Mediterranean conditions affected by the starting quality of the substrate and by site aspect?

A sampling of the area was carried out regarding these two factors. The data were subjected to correspondence analysis, which showed the progressive replacement of species related to succession, variation along slopes, with a tight interaction between both phenomena. The correspondence between vegetation change and slope geomorphology is closer as succession progresses.</style></abstract></record></records></xml>
