Whereas most studies have explored the traits of exotic species in the context of the introduced community, functional comparisons of entire assemblages of species in their native and introduced communities have rarely been analysed. Taking advantage of the unidirectional invasion of plant species of European origin (i.e. colonizers) into California, this study aims to investigate the relative importance of plant traits, environmental factors and invasion status in biological invasions.We compared the functional structure (i.e. trait composition and diversity) along resource availability gradients in recipient and native Mediterranean grassland communities in California and Spain, respectively. Traits were related to resource use in above-ground and below-ground organs and reproductive strategy. We also investigated how niche differences vary along environmental gradients between coexisting colonizer and native species assemblages within communities.There were clear differences in the functional structure of Mediterranean grassland communities between regions, which were associated with the resource availability gradient. Paradoxically, the most acquisitive communities occurred in resource-poor sites, highlighting that rapid acquisition and use of resources permit species to cope with environmental stress through stress avoidance. In Spain, colonizer species had greater specific leaf area than non-colonizers. Yet, differences between colonizer and non-colonizer species in Spain for other traits were mostly absent and did not change along the gradient. This might be a result of the greater native species richness as a consequence of the agricultural practices that have taken place in Europe for millennia and reflect that the entire species pool of grasslands is adapted to agricultural landscapes. In comparison, in California, colonizer species were more acquisitive in their use of resources than natives under favourable conditions, but functionally converged in resource-limited sites.Synthesis. These results underscore that the importance of niche differences between native and colonizer species as a community assembly mechanism is strongly subjected to the influence of habitat filtering. Trait comparisons are context dependent, and a correct interpretation of filtering processes in community assembly requires a regional perspective.}, language = {en} } @misc{RodriguezCalcerradaSalomonGordalizaetal., author = {Rodr{\´i}guez-Calcerrada, Jes{\´u}s and Salom{\´o}n, Roberto L. and Gordaliza, Guillermo G. and Miranda, Jos{\´e} C. and Garcia de la Riva, Enrique and Gil, Luis}, title = {Respiratory costs of producing and maintaining stem biomass in eight co-occurring tree species}, series = {Tree Physiology}, volume = {39}, journal = {Tree Physiology}, number = {11}, issn = {1568-2544}, doi = {10.1093/treephys/tpz069}, pages = {1838 -- 1854}, language = {en} } @misc{GarciadelaRivaViollePerezRamosetal., author = {Garcia de la Riva, Enrique and Violle, Cyrille and P{\´e}rez-Ramos, Ignacio Manuel and Mara{\~n}{\´o}n, Teodoro and Navarro-Fern{\´a}ndez, Carmen M. and Olmo, Manuel and Villar, Rafael}, title = {A Multidimensional Functional Trait Approach Reveals the Imprint of Environmental Stress in Mediterranean Woody Communities}, series = {Ecosystems}, volume = {21}, journal = {Ecosystems}, number = {2}, issn = {1435-0629}, doi = {10.1007/s10021-017-0147-7}, pages = {248 -- 262}, language = {en} } @misc{GarciadelaRivaPrietoVillar, author = {Garcia de la Riva, Enrique and Prieto, Iv{\´a}n and Villar, Rafael}, title = {The leaf economic spectrum drives leaf litter decomposition in Mediterranean forests}, series = {Plant and Soil}, volume = {435}, journal = {Plant and Soil}, number = {1-2}, issn = {0032-079X}, doi = {10.1007/s11104-018-3883-3}, pages = {353 -- 366}, abstract = {BACKGROUND AND AIMS: Leaf litter decomposition is an important process controlling nutrient cycling in most terrestrial ecosystems. We evaluated the relationships among traits of green leaves and decomposition rates of leaf litter (k) at different environmental scales and organisational levels (species and community). We also assessed the relationships at community level between k and the Leaf Economic Spectrum (LES) and between k and different soil variables. METHODS: We measured leaf traits in 38 woody species distributed in nine sampling sites along a topographic gradient in southern Spain. Leaf litter was collected for each species in each sampling site and incubated in a microcosm experiment with soil collected from the top 20 cm of each site. RESULTS: We found positive relationships between k and specific leaf area (SLA), leaf N, K and P and negative relationships with leaf dry matter content (LDMC) and leaf C isotopic composition (δ¹³C), both at species and community levels. Decomposability was positively related with the first PCA axis describing the LES and the relationships were consistent across all sites and within different zones or topographic positions. In addition, community weighted mean values of leaf traits (LESCWM) were stronger predictors of litter decomposition than soil variables. CONCLUSIONS: A major finding of the present study is the main role that leaf traits, and the covariation among them (LES), play on decomposition process in Mediterranean ecosystems both at the species and community levels. In summary, our results support the idea that the suites of leaf traits have a strong control on the pace of C cycling, being the best drivers of decomposition processes under similar climatic conditions.}, language = {en} } @misc{GarciadelaRivaGodoyCastro‐Diezetal., author = {Garcia de la Riva, Enrique and Godoy, Oscar and Castro-D{\´i}ez, Pilar and Guti{\´e}rrez-C{\´a}novas, Cayetano and Vil{\`a}, Montserrat}, title = {Functional and phylogenetic consequences of plant invasion for coastal native communities}, series = {Journal of Vegetation Science}, volume = {30}, journal = {Journal of Vegetation Science}, number = {3}, issn = {1654-1103}, doi = {10.1111/jvs.12748}, pages = {510 -- 520}, language = {en} }
