O que ganhamos 'confundindo' riqueza de espécies e equabilidade em um índice de diversidade?

Abstract: MELO, A.S. What do we win 'confounding' species richness and evenness in a diversity index? Biota Neotrop., 8(3): http://www.biotaneotropica.org.br/v8n3/en/abstract?point-of-view+bn00108032008. Abstract:In Community Ecology and in many applications of Conservation Biology, diversity means variety of species, which may or not include information on the relative importance of each species. Diversity is one of the most important attributes in the study of communities and, as a result, many methods are available t… Show more

“…The first measure is an important method for analyzing community evenness through the curve's inclination (Magurran, 2004;Melo, 2008), while the second is a direct measure of evenness based on Shannon's diversity index (Magurran, 2004). Species accumulation against sample effort was analyzed using sample-based rarefaction calculated through the Mao Tau method with 95% confidence intervals (Colwell & Coddington, 1994;Magurran, 2004).…”

“…Diversity indices have been used in ecological studies as an alternative to species richness (Magurran, 2004;Melo, 2008). One of the major advantages of diversity indices is their capacity of concentrating two community attributes (species richness and evenness) in a single measure (Melo, 2008).…”

“…Isto é conseqüência da existência de três espécies predominantes (Cyathea phalerata, Eugenia schottiana e Guapira obtusata) e de uma menor abundância de espécies raras na área 1. Esta análise seguiu a indicação de autores que sugerem a utilização deste método de ordenação da diversidade, pois a utilização de um único índice poderia trazer conclusões incorretas a este respeito (Lewis et al 1988;Kindt et al 2006;Melo 2008).…”

“…com o intuito de padronizar o esforço amostral. Este método auxilia na solução do problema da falta de critério na escolha dos índices de diversidade (Melo 2008).…”
