“…Although the growth pattern of Cohorts C and D might differ from the pattern suggested from Cohorts A and B, Cohorts C and D may also have lived for less than 2 years, because these cohorts were discernable for at most 7 months in total. The maximum longevities estimated for N. squamulata, 2 years, are shorter than the estimates for confamilial species on hard-bottom shores (Table 3): 3 years for Heminerita japonica (Dunker) in central Japan (Nakano & Nagoshi 1980, 1983; 3 to 5.5 years for N. atramentosa in New South Wales (Underwood 1975); 4 years for Nerita polita L., and 12 years for Nerita albicilla L. on the Great Barrier Reef (Frank 1969).…”

In contrast to the abovementioned molluscs, only one short recruitment within a year is indicated for N. squamulata's confamilial species on hard-bottom shores (Table 3): August to October for H. japonica (Nakano & Nagoshi 1980, 1983; May for N. atramentosa (Underwood 1975); and May to June for N. albicilla (Frank 1969).…”

Life-history traits of a gastropod, Nerita squamulata Le Guillou 1841, on a subtropical cobbled shore disturbed by sand

Cobbled shores in subtropical Japan are small and disturbed by sand transported from terrestrial runoff. How benthic organisms live in such a harsh environment has been seldom studied. On a cobbled shore at Ishigaki Island, the present study investigated the life-history traits of the gastropod, Nerita squamulata Le Guillou 1841. Seasonal quadrat samplings showed that the neritid density decreased when and where sand covered cobbles, indicating impact of sand on the neritid. Monthly frequency histograms of the shell width suggested that the neritid lives less than 2 years and recruits as individuals of 1-4 mm shell width in both May-August and February. With the possible short longevity and frequent recruitments, the neritid population may quickly recover after the disturbance by sand.

“…Gastropods were counted in 10 0.25 m2 quadrats arranged contiguously to form a 1 X 2.5 m rectangle in the middle of the study area at each height. Rates of mortality of prey were calculated as the slope of the regression of log density on time (Underwood, 1975). The second experiment investigated the effects of height on the shore and distance from the nearest crevice on predation by Morula marginalba of a highly-preferred species of prey, the oyster Saccostrea commercialis (Iredale & Roughley) (see Moran, 1980;Moran et al, 1984).…”

Three short-term experiments (6 mo to 1 yr) were done in a preliminary attempt to determine the importance of predation by the muncid whelk Morula rnarginalba Blainville in rocky intertidal communities in New South Wales (Australia). In 2 experiments, whelks were manually removed from some sites, leaving control sites undisturbed. In the third experiment, crevices were filled with concrete, thus removing shelters needed by the whelks and therefore reducing the density of predators. The predators were shown to affect the structure of the community on each shore, but the effects varied considerably among the experiments. Highly preferred prey -oysters and the limpet Patelloida 1atisMgata (Angas) -were eliminated by whelks. Less-preferred species -such as the barnacle Chamaesjpho columna Spengler -were reduced in density where the alternative prey were also less preferred. When other, more favoured prey were present, species low in the preference rankings were ignored by the whelks. The interpretation of simple removals of predators from intertidal systems are made difficult by the patterns of preference for different species by the predator, and by temporal and spatial variations in the availability of these species.

“…Both in mensurative and experimental studies the grazing gastropods Nerita atramentosa and Bembicium nanum were negatively influenced by increasing sediment load (Daly & Mathieson 1977, Seapy & Littler 1982, Littler et al 1983). Both of these species graze on microalgae that is typically refreshed on the rock substratum with each successive tide (Underwood 1975(Underwood , 1984, and individuals were thus likely to reduce feeding activity or move out of areas that received sediment and reduced Some gastropods displayed positive associations and responses to increasing cover and addition of sediment on the rock platform, including the grazers Austrocochlea porcata and Austrocochlea constricta, the predator Haustrum vinosum, and Cacozeliana granarium (Huff & Jarett 2007). These associations were confirmed by experimental addition of sediment, particularly for the predator H. vinosum and B. granarium, but numbers were small.…”

Sediment disturbance associated with trampling by humans alters species assemblages on a rocky intertidal seashore

Our observations reveal that species living on rocky intertidal reefs can be positively and negatively associated with increasing sediment load. We therefore tested the hypothesis that sediment disturbance, including increased sediment loads associated with trampling by humans, alters the abundance of macroinvertebrates on a sheltered rocky intertidal platform in southern Australia. First we trampled the reef in shallow water at several disturbance intensities, simulating different numbers of people walking on the platform on a rising tide, and determined that sediment load was directly related to trampling intensity. Trampling displaced sediment, and up to an order of magnitude more sediment accumulated on the reef near intensively trampled areas compared to those with natural sedimentation. We then manipulated sediment load on the reef to mimic increased sedimentation due to trampling and other potential human (e.g. terrestrial run-off) and natural (e.g. storms) disturbances, and monitored changes to dominant species. Sediment addition increased the cover and depth of sediment on the reef. Increased sediment load negatively impacted barnacles, but not mussels, which occur naturally bound in a sediment matrix in small depressions on the platform. The dominant grazing gastropods Nerita atramentosa and Bembicium nanum were negatively influenced by increased sediments, although not at levels associated with trampling, whereas other gastropods were not affected or responded positively to increased sediment load. Changing sediment loads, including the cumulative effects of smallscale disturbances such as trampling, can alter macroinvertebrate species assemblages on rocky reefs and favour species that tolerate a range of environmental conditions and habitat types.
