“…indicated such a gradient for harpactacoid diversities on the same sandflat, but on the exposed beach a revers2 gradient occurred with highest diversity at HTM and decreasing toward both LTM and extreme HTM. Such a diversity pattern was also shown by HARRIS (1972) for harpactacoids at Whitstable, England.…”

Solenofilomorphids are of world-wide distribution and live in association with the sulfide system, the anoxic and micro-oxic layers of marine sediments. The 58 species of turbellarians on an intertidal sand flat in North Carolina, U.S.A., formed three species assemblages. The solenofilomorphids are a major part of a sulfide system assemblage which is centered in the midtide region and which is intermediate in density and diversity between the two separate species assemblages in the surface layers of the upper and lower tide regions. Oxygen avoidance does not explain restriction of species to the sulfide system, and food preferences for and behavioral responses to specific bacterial species are suggested as proximal causes for observed distributions.

“…Such patterns have mostly been described for the larger components of fauna on intertidal rocky shores or of benthos in soft-sediments (e.g. Harris 1972, Coull et al 1979, Phillips & Fleeger 1985, Thrush 1986, Morrisey et al 1992a,b, Hewitt et al 1997, Schneider et al 1997. These studies indicate that such patterns are variable and complex.…”

Comparison of patterns of spatial variation of microgastropods between 2 contrasting intertidal habitats

Small-scale spatial variation in the distribution of the macrofauna of marine intertidal shores has long been recognized, but there have been few quantitative studies about the scales of patchy distribution of the microbenthos on rocky shores. Patchiness has important implications for comparative and descriptive studies of distribution and abundance because it confounds comparisons of abundance at the largest spatial scales unless the smaller scales are appropriately incorporated into the sampling designs. Spatial variation in the distribution of a number of species of intertidal microgastropods across 2 different habitats (sediment and coralline turf) in Botany Bay, Australia, is described using a nested, hierarchical sampling design. Significant variation was detected mainly at small scales, ranging from less than 1 to 10 m. Moreover, the species showed different patterns of variation depending on the type of habitat and the time of sampling. There was no relation between these patterns and the taxonomic relations of the species. These data illustrate the scales of variability that must be considered when planning long-term or baseline investigations of microbenthos to assure that the study adequately represents different habitats and that subsequent ecological inferences are valid.

“…Food selection and habitat complexity also play an important role in distribution and abundance of marine organisms (Hacker & Steneck, 1990;Duffy & Hay, 1991;Edgar & Robertson, 1992). Zonation patterns of marine algae and marine invertebrates, especially mussels, barnacles, snails, and limpets, have been intensively studied (Connell, 1961;Harris, 1972;Lewis, 1972;Wolcott, 1973;Branch, 1975;Kennedy, 1976;Kingsbury, 1976;Dixon, 1978;Schonbeck & Norton, 1978;Paine et al, 1985;Mathieson & Hehre, 1986); however, only a few researchers have studied the zonation patterns of rocky intertidal amphipods (Tararam et al, 1986;Buschmann, 1990;Krapp-Schickel, 1993;Baldinger & Gable, 1995). While McBane & Croker (1983) described the seasonal abundance of Hyale nilssonii (Rathke, 1843) in the Gulf of Maine, no one has assessed amphipod zonation in New England, U.S.A.…”

Rocky intertidal organisms are distributed in zones characterized by a few dominant species. In this study, the zonation patterns and the seasonal changes of the gammaridean amphipods were investigated in the rocky intertidal in Long Island Sound, U.S.A. A total of 9,773 amphipods of eight species was collected from the two study sites. The results showed that rocky intertidal amphipods occur in zones, associated with species of algae. The differences in total abundance, the number of species, and the abundance of each of these species of amphipod were shown. The upper zone (Fucus vesiculosus) had fewer species and lower total amphipod abundance than the lower zone (Chondrus crispus) and the two zones did not share all species. In addition, there were differences in the amphipod species composition between the two study sites. Several physical and biological factors may regulate such a pattern of abundance. RESUMENLos organismos del intermareal rocoso están distribuídos en zonas caracterizadas por un pequeñ o nú mero de especies dominantes. En este estudio se investigaron las pautas de zonación y los cambios estacionales en el intermareal rocoso de Long Island Sound, U.S.A. En los dos zonas de estudio se recogieron un total de 9773 amfípodos pertenecientes a ocho especies. Los resultados muestran que los amfípodos del intermareal rocoso están en zonas asociadas con especies de algas. Se presentan las diferencias en la abundancia total, nú mero de especies, y abundancia de cada especie. La zona superior (Fucus vesiculosus) tiene menos especies y menor abundancia total que la zona inferior (Chondrus crispus) y las dos zonas no comparten las especies. Por otra parte, existen diferencias en la composición de especies entre los dos sitios estudiados. Diversos factores físicos y biológicos pueden haber regulado la pauta de abundancia observada.3 )
