Multi-stage demographic approaches, where plant recruitment is explored across multiple and consecutive stages, are essential to obtain a whole overview of the consequences of increasing aridity on tree recruitment and forest dynamics, but they are still rarely used. In this study, we present the results of an experimental rainfall exclusion aimed to evaluate the impact of projected increasing drought on multiple stage-specific probabilities of recruitment in a key tree species typical of late-successional Mediterranean woodlands (Quercus ilex L.). We calibrated linear and nonlinear likelihood models for the different demographic processes and calculated overall probabilities of recruitment along a wide range of microhabitat conditions. Rainfall exclusion altered Q. ilex recruitment throughout ontogeny. Seed maturation, seedling emergence and survival and, to a lesser extent, post-dispersal seed survival were the most sensitive demographic processes to decreased rainfall. Interestingly, both the identity of the most critical stages for recruitment and their specific sensitivity to rainfall manipulation depended largely on the yearly pattern of precipitation. The microhabitat heterogeneity strongly determined the success of recruitment in the study species. The experimental increase in drought displaced the peak of maximum overall recruitment towards the low end of the light gradient, suggesting that the dependence on shrubs for an effective recruitment in Q. ilex could be intensified under future environmental scenarios. In terms of phenotypic plasticity, Q. ilex seedlings responded more strongly to light availability than to experimentally increased drought, which could reduce its ability to persist under on-going environmental conditions due to climate change. Results from this study provide a full picture of the ecological and functional consequences of the projected rainfall reduction on tree recruitment and forest dynamics in two years of contrasting precipitation.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier GmbH.</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%">Baraza, Elena</style></author><author><style face="normal" font="default" size="100%">Zamora, Regino</style></author><author><style face="normal" font="default" size="100%">Hódar, José a</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Species-Specific Responses of Tree Saplings to Herbivory in Contrasting Light Environments: An Experimental Approach</style></title><secondary-title><style face="normal" font="default" size="100%">Ecoscience</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">ainsi</style></keyword><keyword><style  face="normal" font="default" size="100%">analyser</style></keyword><keyword><style  face="normal" font="default" size="100%">arbres ressort comme un</style></keyword><keyword><style  face="normal" font="default" size="100%">clipping</style></keyword><keyword><style  face="normal" font="default" size="100%">compensation capacity</style></keyword><keyword><style  face="normal" font="default" size="100%">d</style></keyword><keyword><style  face="normal" font="default" size="100%">élément clé</style></keyword><keyword><style  face="normal" font="default" size="100%">espèces</style></keyword><keyword><style  face="normal" font="default" size="100%">espèces coexistantes d</style></keyword><keyword><style  face="normal" font="default" size="100%">herbivorie interagissent pour modeler</style></keyword><keyword><style  face="normal" font="default" size="100%">herbivorie sont 2 facteurs</style></keyword><keyword><style  face="normal" font="default" size="100%">la</style></keyword><keyword><style  face="normal" font="default" size="100%">la disponibilité de la</style></keyword><keyword><style  face="normal" font="default" size="100%">la façon dont la</style></keyword><keyword><style  face="normal" font="default" size="100%">le but de ce</style></keyword><keyword><style  face="normal" font="default" size="100%">light availability</style></keyword><keyword><style  face="normal" font="default" size="100%">ligneuses</style></keyword><keyword><style  face="normal" font="default" size="100%">lumière et l</style></keyword><keyword><style  face="normal" font="default" size="100%">performance des gaules d</style></keyword><keyword><style  face="normal" font="default" size="100%">principaux influençant la régénération</style></keyword><keyword><style  face="normal" font="default" size="100%">regeneration niche</style></keyword><keyword><style  face="normal" font="default" size="100%">résumé</style></keyword><keyword><style  face="normal" font="default" size="100%">sapling</style></keyword><keyword><style  face="normal" font="default" size="100%">travail est d</style></keyword><keyword><style  face="normal" font="default" size="100%">une meilleure compréhension de</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.bioone.org/doi/abs/10.2980/17-2-3286</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">17</style></volume><pages><style face="normal" font="default" size="100%">156 - 165</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Light availability and herbivory are 2 major factors affecting the regeneration of woody species, and thus a better perception of how light and herbivory interact to shape the sapling performance of cohabitant tree species emerges as a key issue. The purpose of this work is to experimentally analyze the influence of light conditions on tree responses to browsing. We evaluated the responses to browsing (simulated by mechanical clipping of 50% of current-year shoots) of saplings from 2 deciduous (Acer opalus ssp. granatense and Quercus pyrenaica) and 2 evergreen (Quercus ilex and Pinus nigra ssp. salzmannii) late-successional tree species, measuring an array of morphological, physiological, and biochemical traits. The experiment was performed with saplings grown for 2 y under 3 experimental light environments emulating natural microhabitats: full (open microhabitats), 80% (below pioneer shrub canopy), and 13% (below tree canopy) sunlight. Clipping affected biomass distribution, growth, and sapling size, while only slight physiological and biochemical effects were detected. Species characteristics and the light environment in which saplings grow determine their capacity to recover biomass lost after herbivore damage. Black pine was found to be the least tolerant species to clipping, whereas the broadleaf species displayed greater recovery after clipping. Light scarcity increased the nutritional quality of plants and negatively affected herbivory tolerance of 3 of the 4 species.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record></records></xml>
