<p>In the present study we carried out intensive field work to obtain parameters related to the richness and functional diversity of amphibian species present in a temperate mountain forest region of central Mexico. We found a total of 24 species (9 caudates and 15 anurans). The cloud forest (CF) presented the greatest richness, with 16 species, representing 96% completeness of the inventory. These values were higher than those found in the pine-oak forest (POF) and pine forest (PF). The same pattern of higher species richness in the CF was also observed for true diversity. The composition of the most dominant species was more similar between for POF and PF than between either of these and CF. Our functional diversity results indicated that the CF presented the highest value of functional richness and the lowest value of functional equity; in other words, this environment presents a high differentiation in the functional traits of its amphibian species, a pattern that could perhaps be observed in other groups of animals and plants. These results highlight the ecological importance of the CF in comparison to the POF and PF in terms of specific refuges and habitats for the establishment of a community rich in amphibian species. We believe that our results can help encourage actions to conserve and protect Mexico’s temperate environments, fragile ecosystems with a great capacity to provide all the environmental services on which humans and especially biodiversity depend.</p>
