Many theories of consumer control of communities have come from studies conducted in relatively benign, temperate zone rocky intertidal systems. Here, we examine gastropod grazing and the maintenance of bare space on a dry, wind-swept rocky shore of Patagonia, Argentina. Two limpet species are the primary intertidal grazers. Siphonaria lessoni dominates mid and high intertidal zones, while Nacella magellanica dominates the lower zone. In all zones, limpet densities are positively correlated…

Whole-Community Facilitation Regulates Biodiversity on Patagonian Rocky Shores
TLDR
These results provide the first experimental support of long-standing theoretical predictions and reveal that in extreme climates, maintenance of whole-community diversity can be maintained by positive interactions that ameliorate physical stress.
Monitoring the Intertidal Environment with Biomimetic Devices
Worldwide, the narrow bands of habitat between the tidemarks on coastal shores are inhabited by a variety of marine species which periodically have to cope with stressful terrestrial conditions
Effects of recreational activities on Patagonian rocky shores.
TLDR
Impacts due to recreational activities on benthic communities on a Patagonian rocky shore are described and quantify and the need to establish and implement management actions that contemplate the nature of the disturbance and intertidal level to minimize habitat degradation due to human recreational activities is highlighted.
Effects of physical disturbance on a sub-Antarctic middle intertidal bivalve assemblage
Abstract We present for the first time the vulnerability to disturbance of a bivalve assemblage situated in the middle intertidal zone of the Atlantic coast of the Southern South America (53°36′S,
Predation and interaction strength of octopuses and sea stars on different functional groups of the rocky intertidal shores of the Patagonian coast
Predation is one of the main structuring forces in rocky intertidal communities, though with an effect depending on the environmental context and conditions. On the stressful Patagonia shores of
Factors controlling macroalgae assemblages in a Southwest Atlantic coastal lagoon modified by an invading reef forming polychaete
TLDR
Evaluating the relative importance of consumers and nutrients in controlling macroalgae development on the reefs, and on the sediment in areas without reefs found the effect of an invader ecosystem engineer in the composition of species assemblages may be mediated by other community structuring forces.
Habitat modification in tidepools by bioeroding sea urchins and implications for fine‐scale community structure
TLDR
The results suggest the habitats created by S. purpuratus in addition to its biological activities alter community structure at spatial scales finer than those typically considered for sea urchins.
Introduced and native species on rocky shore macroalgal assemblages: zonation patterns, composition and diversity.
TLDR
This study provides the first assessment of rocky shore macroalgae assemblages from Argentina that incorporates the presence of introduced species and shows that the number of introduced algae species along Patagonian rocky shores had been underestimated.
Influence of Rocky Shore Characteristics on the Foraging Profitability of Eurasian Oystercatchers Haematopus ostralegus
Habitat characteristics and microhabitat of organisms pose a number of choices to foraging species, for example where and how to search for prey, which prey to select and what foraging technique to
Effect of Spartina alterniflora Loisel, 1807 on growth of the stout razor clam Tagelus plebeius (Lightfoot, 1786) in a SW Atlantic estuary
TLDR
Results represent an uncoupling between shell and somatic growth with a positive effect of S. alterniflora on the CI of clams, although a better food quality in the SM may be related to the larger clams CI.

Predation on the rocky shores of Patagonia, Argentina
TLDR
This study represents a preliminary survey of predator distributions and feeding habits on the rocky shores of Argentinean Patagonia and provides important baseline data to evaluate trophic linkages and predatory effects on Patagonian rocky shores.
THE COMMUNITY STRUCTURE OF WESTERN ATLANTIC PATAGONIAN ROCKY SHORES
TLDR
Patagonian rocky shore communities are exposed to unusually harsh physical conditions and consequently are more strongly organized by physical stress than previously studied rocky intertidal communities.
Community Development and Persistence in a Low Rocky Intertidal Zone
TLDR
Results of manipulations during both primary and secondary succession indicate that Littorina littorea, the only large, abundant herbivore in the low zone, has no direct effect on perennating or established Chondrus, or on its extensive, encrusting holdfast.
The effects of grazing by gastropods and physical factors on the upper limits of distribution of intertidal macroalgae
TLDR
Experimental manipulations at midtidal levels were used to test hypotheses about the effects of grazing by molluses and of physical factors during low tide on this pattern of algal community structure, and the role of grazing in the diversity and structure of intertidal algal communities.
Some adaptations of gastropods to physical stress on a tropical rocky shore
TLDR
Activity patterns, microhabitat occurrences, and behaviors during low tides of 10 com- mon gastropods inhabiting rocky intertidal shores of the Pacific coast of Panama were examined, indicating intense, complementary, and cyclically occurring biotic and abiotic factors severely limited foraging for the gastropod of this region.
Herbivory and the Seasonal Abundance of Algae on a High Intertidal Rocky Shore
TLDR
Evidence from this study and the literature indicates that the limpets in this habitat are probably consuming more, not less, algae in the winter months, and higher rates of algal production in winter more than compensate for the increased herbivory, and the algae become more abundant.
Algal Zonation in the New England Rocky Intertidal Community: An Experimental Analysis
TLDR
Experimental investigations of the factors affecting zonation of macroscopic, benthic algae in the New England rocky intertidal region demonstrated that biological factors set the lower limits of these plants, and it is suggested that biogeographic ranges of some species may be similarly affected by biotic factors.
Variation and persistence of the middle rocky intertidal community of central Chile, with and without human harvesting
TLDR
The effects of the exclusion of humans from the rocky intertidal at Las Cruces, central Chile are reported on and species diversity and composition in harvested and non-harvested areas diverged.
Food supply, grazing activity and growth rate in the limpet Patella vulgata L.: a comparison between exposed and sheltered shores.
TLDR
Although the overall density declined with decreasing exposure to wave action, the density per unit area of grazeable substance was higher in shelter and in these populations, the mean growth rate was over twice as high on exposed compared to sheltered shores.
Interaction between a fucoid canopy and limpet grazing in structuring a low shore intertidal community
TLDR
The relative roles of a macroalgal canopy and a grazer in structuring a low shore community of a sheltered, rocky intertidal site were examined using a factorial experimental design and grazing pressure rather than the canopy was inhibiting recruitment of the canopy species.
