Later, Good (1953, 1982) proposed a generalized index that included as special cases both Shannons and Simpsons indices. Baczkowski et al. (1997, 1998) generalized the proposed generalization deriving the first four moments and then obtaining a distribution prior to the general

2. "Utilização do método dos povoamentos na caracterização de comunidades bentônicas em trecho do infralitoral consolidado da Enseada das Palmas, Ilha Anchieta, Ubatuba (SP)" / Settlements method for the characterization of hard bottom benthic communities in an infralittoral stretch in Palmas Bay, Anchieta Island, Ubatuba (SP)
The biodiversity characterization of benthic communities in the Brazilian coast is limited to a few works, which studied an area of about 3,400 m2. The objective of this study was to propose a new method, unprecedented in hard bottom marine communities, based in the sampling of landscape heterogeneity units, named physiognomies and settlements, aiming at an
