Overall, we found a net increase in species richness Mussels in samples with mussels (35 species), in contrast to samples where mussels were naturally absent or scarce (27 Rocky shores species).

As coletas foram realizadas no período da manhã, durante a baixamar de uma maré de sizígia nos dias 9 de março e 16 de novembro de 2013, totalizando seis coletas. Para análise da abundância de recrutas, foram feitas raspagens destrutivas, eqüidistantes cerca 20 a 30 m entre si, utilizando quadrados de 20 X 20 cm nos bancos de P. perna , sendo as amostras inseridas no interior de sacos vedado para a retenção do macrozoobentos. Foram feitas análises referentes à riqueza baseadas no Índice de Margalef e de diversidade no índice de Shannon-Wiener, grau de constância, dos grupos tróficos e do índice de importância trófica. As classes Bivalvia e Gastropoda foram representadas por 18 famílias, 21 gêneros e 16 espécies. A classe Gastropoda representou 76,2% das espécies encontradas, enquanto Bivalvia representou 31,2%.

    THE VELIGER The Veliger 48(4):235-242(January 25,2007) O CMS, Inc.,2005 Shell Microstructure of the Patellid Gastropod Collisella scabra (Gould): Ecological and Phylogenetic Implications SARAH E. GILMAN* Section of Evolution and Ecology, and Center for Population Biology, University of California, Davis, Davis, cA 95616-8755 Abstract. Shell microstructure has a long history of use in both taxonomic and ecological research on molluscs. I report here on a study of the microstructure of Collisella scabra, also known as Macclintockia scabra and Lottia scabra. I used a combination of SEM and light microscopy of acetate peels, whole shells, and shell fragments to examine the shell layers and microstructure. Regular growth bands were not present in most shells examined. Several shells showed multiple bands of myostracum, which indicate periods of extreme rates of size change, and may be evidence of abiotic stress. This study also suggests that shell layers previously described as "modified foliated" are "irregular complex crossed lamellar," with both fibrous and foliated second order structures. The presence of fibrous shell structures, in addition to other shared morphological characters noted by previous authors, suggests an affinity with the Lottiidae rather than the Nacellidae. INTRODUCTION scabra shells, and 2) to verify the earlier shell microstructure descriptions, including phylogenetic Shell microstructure has a long history of use in both implications. taxonomic and ecological research on molluscs. Shell growth bands are commonly used as records of individual growth (Frank, 1975; Hughes, 1986; Arnold MATERIALS AND METHODS et al., 1998) and for reconstructing environmental conditions (Rhoads &LuIz,l980; Jones, 1981;Kirby et Collection and Preparation of Shells al., 1998).
