El análisis de componentes principales mostró una clara separación de especies basada en las clasificaciones tradicionales de tolerancia-evasión vs. un eje relacionado a uso de recursos (conservador-adquisitivas). Nuestros resultados sugieren no solo que hay rasgos específicos asociados a las respuestas de estrés climático, si no también que estos rasgos manifestados en las especies proveen diferentes efectos para la mitigación de sequía a través de la prevención de pérdida de agua bajo la copa. Se recomiendan las especies G. ulmifolia y C. alala para mejorar el aprovisionamiento de servicios ecosistémicos de tolerancia a sequía, conservación de agua y producción de pasto. The purpose of was to evaluate the potential of functional ecology as an alternative to respond to specific management needs aimed at guaranteeing the provision of ecosystem services in semiarid agroecosystems of Rivas, to be able to predict or improve the functional capacity of agroecosystems to support climate variability, and more specifically, the contribution of the species to assure biomass production through the year. Our finding suggest not only that there are specific traits associated with responses to climatic stress, but also that this traits manifested in species provide different effects to drought mitigation by preventing understory water loss. We measured actual evaporation under the different canopies trees in relation to the differentiation of the ability of the species to conserve humidity during the end of the drought period. We recommend the species G. ulmifolia and C. alata to improve provisioning of ecosystem services of drought resistance and pasture production as they prove to have well defined different drought responses, prevent a significant amount of evapotranspiration under their canopies during the dry season, and allow enough light transmission to reach the understory to guarantee pasture production. 2014-10-17T15:38:03Z 2014-10-17T15:38:03Z 2011 Tesis de maestría 376432 https://repositorio.catie.ac.cr/handle/11554/2206 info:eu-repo/semantics/openAccess application/pdf CATIE, Turrialba (Costa Rica) |
