Resumen:
Background: Heteroflorum (Fabaceae) is a monospecific genus endemic to
western Mexico. Community attributes of the forest where H. sclerocarpum
is found are scarcely known, as well as its similarity with other
tropical seasonal forests.
Question: What is the composition, structure, and diversity of the
tropical deciduous forest where H. sclerocarpum is physiognomically
dominant?
Study site and date: The buffer area of the Zicuiran-Infiernillo
Biosphere Reserve, in the Churumuco municipality of Michoacan, Mexico,
in 2014.
Methods: In three 0.1-ha sites, we sampled trees with a diameter at
breast height >= 1 cm and lianas whose rooted stem had a diameter of >=
1 cm. We calculated the density, biomass, rank-abundance, rank-basal
area curves, as well as alpha and beta diversity measures for each site.
Results: We recorded 64 species from 21 families in 0.3 ha. Fabaceae had
the highest number of genera, species, individuals, and biomass in all
sites sampled. The sites varied in richness (33-41 species), density
(176-247 individuals), basal area (2-2.9 m2), and maximum height of
trees (12-16 m). Rank-abundance curves differed significantly among
sites. Rarefaction curves showed that D-0 alpha and D-1 alpha did not
differ among sites, while D-2 alpha separated one of the sites, which
also showed a different diversity profile. Beta diversity did not show a
strong species turnover among sites (D-0(beta), 1.38-1.45; D-2(beta),
1.35-1.56).
Conclusions: The composition of the forest sampled was similar to other
seasonal forests, while the density and diversity were among the lowest
values.
