Patterns of richness and distribution of Cactaceae in the Serra da Mantiqueira, Southeast Brazil, and implications for its conservation Acta Botanica
Gonzaga,Diego Rafael; Peixoto,Ariane Luna; Menini Neto,Luiz.
Abstract This study aimed to analyze patterns of richness and distribution of Cactaceae in the Serra da Mantiqueira (SM), a mountain range located in Southeast Brazil, and assess its conservation status. We compiled distribution data from the literature and 16 herbaria and plotted it on a map divided into grid squares of 0.5°. Richness, collection effort and similarity among grid squares were analyzed for the 33 taxa recorded in SM (five of which are endemic). Maciço do Itatiaia (in southern SM), Serra do Brigadeiro and Serra do Caparaó (in northern SM) are the richest areas. Collection effort and richness were correlated (R²=0.75). Similarity analysis revealed five clusters, one of which is composed of high elevation areas with a vegetation mosaic; the...
