DELGADILLO-MOYA, Claudio; CARDENAS-SORIANO, María de los Ángeles; GALVEZ-AGUILAR, Víctor Manuel  e  SANCHEZ-GONZALEZ, Arturo. Mosses of Los Mármoles National Park, Hidalgo, Mexico. Bol. Soc. Bot. Méx [online]. 2011, n.89, pp.19-26. ISSN 0366-2128.

Los Mármoles National Park, in the Mexican state of Hidalgo, is an area of floristic and phytogeographical interest. An adequate knowledge of its biota is a requisite before adopting conservation measures, especially for locally unknown plant groups such as the mosses. For this research, 573 specimens representing 129 species and varieties of mosses, were obtained from the main types of vegetation. Non-parametric richness estimators (Jackknife and Bootstrap), indicate that the local moss inventory contains between 78 and 87% of the expected infrageneric taxa. The moss flora includes such species as Aloina rigida and Claopodium pellucinerve that extend southwards their known distribution, and Campylopus anderssonii that extends it northwards. The identified patterns of distribution are arranged by number of species, as follows: Wide distribution, Mesoamerican, Caribbean, Boreal, Endemic, Southern, and Chihuahuan. Zimapán, the largest of the four municipalities represented in the park, is the most diverse with 90 moss species and varieties; in contrast, Pacula, with the smallest surface area, has the smallest moss flora, with 39 taxa.
