| Sumario: | The cloud forest is one of the most important ecosystems in Mexico since its levels of biodiversity. The importance of its continuity for the maintenance and operation of the diversity of environmental services it provides is evident. However, the pressure exerted by deforestation and land use change, as well as climate change has put its continuity at risk. In the case of San Luis Potosí there are few works about this type of ecosystems, and the need to integrate new approaches and new tools to enrich conservation strategies is highlighted. The present work aims to know the relationship between functional diversity and chronic disturbance in this ecosystem. The samplings were carried out through conglomerates in six different locations. The functional diversity was evaluated from the vegetal attributes Specific Foliar Area (AFE), Chlorophyll Content (CC) Maximum Height (ALT), and Dry Matter Content (CMS) contained in the functional diversity metrics RAO, MPDF, and MNFD. Through a principal component analysis, a chronic disturbance index was generated from a set of disturbance components and the contribution of each of the components was determined. A correlation was made between the functional diversity metrics and the disturbance index to determine the relationship between them. The results obtained showed adequate levels of functional diversity for most of the analyzed localities. The chronic disturbance index showed differences between localities, but there is no significant relationships between their components and the functional diversity, suggesting that cloud forest is resilient to disturbance maintaining environmental services in presence of intermediate disturbance like the low advantage in the studied localities. Throughout our results, we propose actions to improve the strategies of monitoring and diagnostic in the PACC-SESMO for the cloud forest. |
