“…In such situations, the highest (or lowest depending on the direction of the index) values cannot be associated to the lowest impact situation and the same index value may be observed at different degrees of impact. In an evaluation of the EcoQS of undisturbed soft-bottoms of the Reunion Island, Bigot et al (2006; observed a polynomial relationship between AMBI and H", apparently driven by an incoherent classification of sites by H": the highest values of H" were concentrated in the Good class rather than the High, while sites with ~ 2.0 < H" < 3.5 were classified as in High, Good or Moderate conditions. Facing a conceptually identical problem, Muxika et al (2007) in the paper where M-AMBI is described for the first time, excluded the use of density and biomass as parameters in the multimetric because of their bimodal (nonmonotonic) response to a source of disturbance.…”

“…The eastern coastline of Bahrain is considered a hotspot for high concentrations of hydrocarbons (De Mora et al, 2010) and heavy metals (De Mora et al, 2004). Effects of industrial effluents on macrobenthic assemblages involve changing the composition of the community structure, increasing the numbers of opportunistic species, and reducing the general biodiversity and abundance (Bigot et al, 2006;Frouin, 2000). Naser (2010a) investigated the community structure of macrobenthos inhabiting a subtidal area subject to effluents containing hydrocarbons and heavy metals from the main oil refinery in Bahrain.…”

“…6.5 Macrofauna bentônica 6.5.1 Padrão geral da comunidade O padrão de dominância da macrofauna de fundo inconsolidado, no qual os anelídeos poliquetas são os mais representativos, é freqüentemente observado em estudos que abordam estas comunidades em regiões costeiras em todo o mundo (Belan, 2003;Lancellotti e Stotz, 2004;Venturini et al, 2004;Lu, 2005;Hernández Arana et al, 2005;Bigot et al, 2006). Os anelídeos poliquetas são os organismos macrofaunais mais abundantes e ricos em espécies do Canal de São Sebastião (Muniz e Pires, 1999;Heitor, 2002;Arasaki et al, 2004).…”

“…Estes organismos, especialmente os da infauna, têm sido utilizados como monitores in situ do grau de perturbação de um ecossistema, por serem sedentários e apresentarem ciclo de vida relativamente longo, além de responder rapidamente a eventuais fatores estressantes (Irving, 1991;Rizzo e Amaral, 2000;Shratzberger et al, 2003;Lu, 2005;Bigot et al, 2006). Devido a essas características, a estrutura de comunidades bentônicas vem sendo amplamente utilizada, em regiões costeiras, como uma importante ferramenta tanto em programas de monitoramento quanto em estudos de avaliação do grau de poluição ambiental (Belan, 2003;Gomez Gesteira et al, 2003;Arasaki et al, 2004;Hernández Arana et al, 2005;Lu, 2005;Bigot et al, 2006) para descrever mudanças no espaço (com aplicações sobre o monitoramento da fonte de poluição) e no tempo (com aplicações na descrição das mudanças de estado do sistema marinho) (Majeed, 1987;Muniz e Pires, 1999;Lu, 2005).…”
