ESPARZA-OLGUIN, Ligia Guadalupe; VARGAS-CONTRERAS, Jorge A.; MARTINEZ-ROMERO, Eduardo y ESCALONA-SEGURA, Griselda. Diversity and biomass of the tropical forest surrounding the Volcán de los Murciélagos in Campeche, Mexico. Ecosistemas y recur. agropecuarios [online]. 2019, vol.6, n.16, pp.79-90. Epub 01-Oct-2019.

The diversity of vegetation surrounding the El Volcán de los Murciélagos refuge has not been previously described; therefore, the objective of this study was to determine its floristic composition, structural diversity and stored biomass. Eight sampling sites were established, both near and far from the rim. A total of 2,844 individuals were counted in a 5 000 m2 sampling area. Species richness was 84, distributed in 34 families. The most abundant species were Croton oerstedianus, Eugenia winzerlingii and Drypetes lateriflora, with Astronium graveolens being the only species in NOM-059-SEMARNAT-2010. The basal area varied between 9.55 and 26.05 m2 ha−1 and the density between 4 288 and 8 272 ind ha−1. The horizontal and vertical structure have an inverted J-shaped pattern. The structural diversity values have a positive relationship with biomass accumulation, which varied between 4.23 and 51.95 Mg ha−1 Results indicate that the heterogeneity and diversity of the vegetation surrounding the El Volcán de los Murciélagos cave constitute habitat characteristics that influence the bat species that inhabit the cave. The structural conditions and diversity correlated with biomass accumulation reinforce the need to generate conservation strategies for this multi-specific refuge.
