Abstract

This study aims to compare the results of spatial structure obtained between the classic and quadrat variance methods. Two species were analised, Vernonia aurea and Duguetia furfuracea. The Poisson distribution (random pattern), the Negative Binomial distribution (aggregate pattern), the BQV, TTLQV and PQV methods, the ratio variance:mean (I), the Green coefficient (Ig) and the Morisita´s index of dispersion (Im) were used to detect the populations spatial pattern. An aggregated spatial pattern distribution was detected through both methodologies, with similar results as for the aggregation level and the complementation of the information in different scales between classic and quadrat variance methods. Thus, the utilization of these statistic methods in studies of the spatial structure is recommended, given that tests are robust and complementary and field data samples are easy to collect
