Patterns of tree species richness in Jalisco, Mexico: relation to topography, climate and forest structure

摘要: The objective of this study was to identify the major environmental variables and components forest structure associated with variability in tree species richness on a network 806 permanent plots State Jalisco, Mexico. Tree data recorded sample were used characterize by type climatic conditions (temperature precipitation) State. Species composition other diversity indices also calculated. Explanatory identified Poisson regression cover type, elevation, basal area, canopy closure, winter precipitation as being important changes richness. An “extreme quantile curve estimation” approach then approximate boundary that represented maximum potential response various levels variables. Maximum decreased increasing elevation. relationships between followed hump-back unimodal model, intermediate values supporting largest We believe results current will contribute further development conservation plan for
