REYNEL, Carlos et al. Number of species according to minimum diameter measured in the montane and premontane forests from selva central of Peru. Ecol. apl. [online]. 2021, vol.20, n.1, pp.35-51. ISSN 1726-2216.

Data from eight Permanent Plots of 1 ha (including all plants ≥ 10 cm) and similar number of RAP Transects of 0.1 ha (including all plants ≥ 2.5 cm) established in primary tropical humid forests, premontane (940 - 1 150 masl) and montane (2 078 - 2 770 masl) in the Chanchamayo valley (Junin / Peru) are here used to finding to which extent the minimum recorded diameter influences tree diversity as found in forest inventories. In each diameter class, both the species percents and Fisher´s Alpha values are considered. Our results show that forest inventories including only large diameters, e.g. ≥ 40 cm DBH, capture a low percent of the species (29.2% and 22.9% in premontane and montane forests, respectively); Fisher´s Alpha values are coincident with these findings.
