Afinidades de la flora genérica de algunos bosques mesófilos de montaña del nordeste, centro y sur de México: un enfoque fenético

Abstract

A FLORISTIC ANALYSIS OF THE COMPOSITION AT GENERIC LEVEL OF SEVERAL CLOUD FORESTS FROM NORTHEASTERN, CENTER AND SOUTHERN MEXICO IS PRESENTED. AN UPGMA DENDROGRAM WAS CONSTRUCTED, USING CLUSTER ANALYSIS THROUGH SRRENSEN'S SIMILARITY INDEX. IN THIS STUDY THE CLUSTERING OF CLOUD FORESTS FROM DIFFERENT PHYTOGEOGRAPHICAL PROVINCES IN APPARENTLY UNEXPECTED HETEROGENEOUS GROUPS WERE EVIDENT. IN THIS SENSE THE CLOUD FORESTS STUDIED SHOULD NOT BE CONSIDERED MONOTOPIC AND EFFORTS TO CONSERVE THEM SHOULD CONSIDER LOCAL, PROVINCIAL AND REGIONAL RESERVES TO REPRESENT THE NATURAL DISTRIBUTION AND HETEROGENEITY OF THE CLOUD FORESTS OF MEXICO.
