Ecological-Niche Modeling and Prioritization of Conservation-Area Networks for Mexican Herpetofauna

摘要: : One of the most important tools in conservation biology is information on geographic distribution species and variables determining those patterns. We used maximum-entropy niche modeling to run models for 222 amphibian 371 reptile (49% endemics 27% threatened) which we had 34,619 single records. The planning region southeastern Mexico, 20% country's area, includes 80% herpetofauna, lacks an adequate protected-area system. probabilistic data build herpetofauna use prioritizing areas three target groups (all threatened endemic species). accuracy species-distribution was better than it all species. Forty-seven percent has been deforested additional with 13.7% 88.6% more native vegetation (76% 96% are outside current system) needed. There overlap 26 main selected conservation-area network prioritized preserve groups, proportion types needed their constant: 30% pine oak forests, 22% tropical evergreen forest, 17% low deciduous 8% montane cloud forests. fact that different require same habitat suggests forests support highest should therefore be given priority over other inclusion protected Mexico. Resumen: La informacion sobre la distribucion geografica de las especies y que determinan esos patrones es una herramientas mas importantes biologia conservacion. Utilizamos el modelado maxima entropia del nicho para correr modelos anfibios reptiles endemicas amenazadas) contamos con registros geograficos individuales. La planificacion esta en sureste comprende superficie pais, incluye carece un sistema protegidas adecuado. datos probabilisticos construir utilizarlos priorizacion conservacion tres grupos focales (todas especies, amenazadas). precision los fue mejor amenazadas todas especies. Cuarenta siete porciento ha sido deforestada se requieren adicionales a vegetacion nativa estan afuera actual protegidas). Hubo traslape principales seleccionadas red priorizada preservar focales, proporcion tipos requeridos su constante: bosques pino-encino, bosque perennifolio, bajo deciduo montanos niebla. El hecho diferentes misma sugiere pino encino soportan mayor y, por lo tanto, deben ser priorizados encima otros Mexico.
