However, facilitation efﬁciency is known to depend on the environmental context and the particular pair of interacting species. Understanding these context- and pair-speciﬁc dependences is fundamental to understanding Mediterranean vegetation dynamics and to improving the use of nurse-based plantation for restoration. We assessed the effectiveness of nurse-based plantation and the signiﬁcance for post-ﬁre restoration of some assembly rules mediated by facilitation. In two nearby areas of different burning ages, we compared seedling establishment of 13 tall shrubs and trees planted in open ground and under nurses. Nurses and planted seedlings were selected from different life-forms. Tests of the assembly rules were provided by the partitioning of the statistical interaction effect between nurse and planted seedling life-forms in a two-factor design. Nurse-based plantation increased seedling survival 2–9 times compared to plantation in open ground, depending on the year. The higher efﬁciency of nurse-based plantation was consistent for the two burned areas and occurred in many species even in years with contrasting rainfall. We detected pair-speciﬁc differences in the efﬁciency of facilitation. This pair-speciﬁcity was partly explained by the dependence between life-forms of nurse and guest species, suggesting the existence of assembly rules. Our results conﬁrm that nurse-based plantation would be an appropriate post-ﬁre restoration technique in Mediterranean mountains under dry-subhumid climate, but suggest that attention to the life-form assemblage rules is needed for an efﬁcient implementation of such technique.</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%">Fedriani, J M</style></author><author><style face="normal" font="default" size="100%">Rey, P J</style></author><author><style face="normal" font="default" size="100%">Garrido, J L</style></author><author><style face="normal" font="default" size="100%">Guitián, J</style></author><author><style face="normal" font="default" size="100%">Herrera, C M</style></author><author><style face="normal" font="default" size="100%">Medrano, M</style></author><author><style face="normal" font="default" size="100%">Sánchez-Lafuente, A M</style></author><author><style face="normal" font="default" size="100%">Cerdá, X</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Geographical variation in the potential of mice to constrain an ant-seed dispersal mutualism</style></title><secondary-title><style face="normal" font="default" size="100%">Oikos</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">ant-plant mutualism (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">seed dispersal</style></keyword><keyword><style  face="normal" font="default" size="100%">seed predation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2004</style></year></dates><publisher><style face="normal" font="default" size="100%">Munksgaard</style></publisher><volume><style face="normal" font="default" size="100%">105</style></volume><pages><style face="normal" font="default" size="100%">181-191</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Pre- and post-dispersal Helleborus foetidus (Ranunculaceae) seed predation by mice Apodemus sylvaticus as well as post-dispersal seed removal by ants was studied, during two years, in six plant populations within three geographical regions (Caurel, Cazorla and Mágina) of the Iberian Peninsula. An observational approach revealed strong interregional differences in seed predation by mice during the pre-dispersal phase, with high and similar rates of predation in Cazorla and Mágina and much lower rates in Caurel. There were also significant inter-annual variations on pre-dispersal seed predation by mice, while the existing habitat-related differences (of lower magnitude) were not consistent across regions. Field experiments based on seed-offering exclosures, showed that, despite some interregional variation, post-dispersal seed removal by ants was consistently high through all spatial and temporal scales considered, with most seeds being removed within 48 h. Conversely, post-dispersal seed predation by mice was highly variable among regions, being very high in Cazorla and minimal or absent in Caurel and Mágina. Interestingly, in Cazorla, in presence of mice, the number of seeds removed was rather independent of the presence/absence of ants, while under mice exclusion, it was determined by the presence/absence of ants. Conversely, in Caurel, the number of seeds removed by each remover agent (ants or mice) was independent of the presence/absence of the other agent. Thus, though uniquely in Cazorla, mice limited the number of seeds available to ants and, therefore, in this region could potentially have interfered on the development of seed traits that enable ants to efficiently harvest them. Our results support the notion that geographical variation over the Iberian Peninsula of mice seed predation may have promoted a mosaic of well-matching and mismatching situations between H. foetidus diaspore traits and the characteristics of ant communities, which is consistent with some recent theories on the geographical structure of interactions.</style></abstract></record></records></xml>
