“…Hawkins & Hartnoll 1983, Gray & Naylor 1996, Santini et al 2004, there have been no comparisons with natural rocky habitats. How changes to natural habitats might affect patterns of movement and, hence, the grazing activity of limpets remains, therefore, unexplored.…”

“…Intertidal gastropods can display temporally variable and unpredictable patterns of movement and activity, responding to sudden changes in environmental conditions, like wave-wash (Wells 1980, Hawkins & Hartnoll 1983, Little 1989, Crowe 1999, Chapman 2000c) and weather (Hamilton 1977 Underwood (1977) and by Mackay & Underwood (1977) to describe the movement of non-homing C. tramoserica on the coast of NSW (Australia). These authors showed, however, that individuals that were not homing moved at random, consistently over periods of time ranging from 1 to 14 d. Since their studies were done on horizontal rocky platforms at exposed sites, exposure to wave action, the slope of the substratum, or a combination of the two, could have affected the orientation of the movement of C. tramoserica (Hawkins & Hartnoll 1982, Chapman & Underwood 1992, Santini et al 2004). …”

Artificial structures are becoming common features of the landscape in shallow waters of urban areas, but very little is known about their ecology. In Sydney Harbour (NSW, Australia), intertidal seawalls replace considerable portions of natural habitats, including rocky shores. Previous studies have shown that seawalls and rocky shores generally support similar assemblages of plants and animals, with important differences in relative abundances of some species. The behaviour of key consumers can have a fundamental role in structuring benthic assemblages, and it is, therefore, necessary to assess whether it is changed by the replacement of natural habitats with artificial structures. This study compares patterns of movement of the common patellid limpet Cellana tramoserica between seawalls and vertical rocky shores. The distances displaced, the orientation of movement and the homing behaviour of marked individuals were recorded from day to day, over a period of several tidal cycles (14 d) and for a longer period (ca. 3 mo), on several seawalls and rocky shores. Short-term patterns of movement (1 to 14 d) did not differ between structures. In contrast, after 3 mo, although the orientation of the movement remained random on both kinds of structures, limpets on seawalls had dispersed longer distances and tended not to retain their original positions. These results suggest that long-term dispersal of C. tramoserica, rather than foraging bouts, could be altered by the replacement of rocky shores with artificial structures. Differences in use of habitat by key consumers should be incorporated in models aimed at identifying the mechanisms responsible for the occurrence of different assemblages on natural and artificial structures.

“…Similarly, Drent et al (2004) found that gill-to-palp ratios (which determine particle sorting efficiency) of the deposit feeding clam, Macoma balthica, were flexible and depended upon the grain size of the material that the clams were feeding on. In general, intertidal grazers typically change their feeding activities depending on the duration of aerial exposure (Newell et al 1971;Zeldis and Boyden 1979;Little 1989;Little et al 1991;Santini et al 2004, but not always, e.g., Underwood 1984, but the situation is not as clear for suspension-feeders (Morton et al 1957;Griffiths and Buffenstein 1981;Widdows and Shick 1985;Bayne et al 1988;Kreeger et al 1990;Charles and Newell 1997). At least some suspension-feeders have the ability to compensate for differences in water turbidity with flexibility in the sizes of their feeding organs (Payne et al 1995;Honkoop et al 2003;Drent et al 2004;Dutertre et al 2007).…”

“…The timing of foraging of nearly all intertidal grazers shows some tidal correlation, presumably driven by physical stress or predation risk (Little 1989, Chapman & Underwood 1992a. Foraging behaviour can, however, be labile within the same species, varying temporally, for example, with different seasons (Ng & Williams 2006) and diurnal and tidal cycles (Chelazzi 1982, Santini et al 2004, 2011. Such behaviour can also vary spatially with different site locations (Hartnoll & Wright 1977), habitats (Hawkins & Hartnoll 1982) and tidal levels (Williams & Morritt 1991).…”

Small-scale temporal and spatial variability in foraging behaviour of the mid-shore gastropod Nerita yoldii on seasonal, tropical, rocky shores

Describing temporal variation in the foraging behaviour of intertidal gastropods is important to gain an understanding of the environmental conditions that constrain their activity patterns. Foraging behaviour in the tropical gastropod Nerita yoldi was mainly determined by the tidal cycle: individuals foraged when they were awash, or emersed when the rock was wet, migrating downshore to forage and upshore when they returned to refuges. Apart from tidal influences, foraging in N. yoldii also varied with season and tidal state. Individuals were generally more active in summer than in winter and on neap than spring tides; although small-scale daily variation existed. Such temporal variation may be caused by several interacting environmental variables, especially air temperature, pressure and irradiance, which influence physical conditions as well as individuals' metabolism. Individual foraging patterns were also highly labile between seasons: most individuals would stop and remain stationary on the open rock surface in winter, but returned to refuges after foraging in summer, a pattern probably driven by physical stress. The foraging behaviour of N. yoldii, therefore, is predictable on a coarse scale, in terms of when they are active, but highly labile in duration and foraging range, which indicates the importance of local, daily variation in environmental factors controlling foraging on shores that have strong temporal changes in abiotic conditions. KEY WORDS: Nerita · Foraging behaviour · Tropical shoreResale or republication not permitted without written consent of the publisher Aquat Biol 16: 177-188, 2012 Such lability in foraging behaviour represents important adaptive traits in organisms (Mery & Burns 2010). Climatic seasonality, for example, is a large time-scale temporal pattern that affects foraging behaviour owing to changes in physical stress, predation pressure and food availability as well as associated changes in tidal and diurnal conditions. As a result, such variation in foraging behaviour can make it difficult to define precise behavioural patterns of a species (Chapman & Underwood 1992a, Ng & Williams 2006, Santini et al. 2011.The gastropod genus Nerita Linnaeus 1758 (Neritacea) has a high abundance and diversity in tropical regions (Vermeij 1973). Most species, such as N. textilis (Chelazzi et al. 1983) and N. polita (Chelazzi 1982) are zonal shuttlers (Chelazzi et al. 1988), which forage from a refuge either up-or downshore during each tidal cycle before returning to their resting level (Chelazzi et al. 1988). Previous observations on the behaviour of Nerita have not, however, investigated longer-term variations in foraging patterns, such as monthly or seasonal variation, al though a longerterm study of N. plicata, N. textilis and N. undata in Kenya showed these species to be more active on spring than neap tides (Ruwa & Jaccarini 1988).Nerita are important herbivores in the Hong Kong rocky intertidal zone (Hill 1980). In contrast to other tropical localities where the foraging beh...
