Analyses of temporal diversity patterns in a stricto sensu Cerrado fragment

We performed a forest inventory in a fragment of stricto sensu Cerrado to evaluate alpha and beta temporal diversity among adult and natural regeneration (NR) strata. Fifteen plots of 1,000 m² (20 × 50 m) were set to sample the adult stratum, and each plot divided in sub-plots of 100 m² (2 × 50 m) t...
