The effects of the north-facing and southfacing aspects on atmospheric parameters, soil water contents (SWCs) and plant water balances were assessed during 18 months including two dry seasons and one wet season. The species studied were the evergreen sclerophyll Quercus suber and the semideciduous shrubs Cistus albidus, Cistus monspeliensis and Lavandula stoechas. Atmospheric parameters were similar in both exposures, but water content of the 30-cm uppermost soil layers was higher under canopy in the south-facing slope during the wet season. Water balances of both slopes were different, and this was related to the lower shrub abundance and the vegetation patchiness observed in the south-facing slope. Autumn plant recovery was faster in the north-facing hillslope and occurred ﬁrst in shrubs. During the whole study, Quercus suber displayed a hydrostable strategy maintaining an optimum water balance in both hillslopes. This was not the case of shrubs that avoided drought using a phenological adjustment and were more affected by aspect. Differences between tree and shrub water economies relied mainly on their respective root systems. The faster recovery of shrubs after the ﬁrst autumn rainfalls allows them to avoid competition with other functional groups for water and nutrients during some days. Leaf-drying curves distinguished the functional behaviour of the tree and the shrubs because stomatal closure occurred at higher relative water content in the former. The coexistence of both functional strategies ensures an efﬁcient use of water and nutritional resources</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></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? 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></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.
