Limpet grazing on a physically stressful Patagonian rocky shore
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 Nace...
متن کاملResilience in intertidal rocky shore assemblages across the stress gradient created by emersion times
A key feature of intertidal marine systems is the well-defined gradient of environmental stress generated by tides. In this study, resilience, i.e. the speed of recovery along this gradient, was explored in a temperate rocky shore system. The purpose was to test whether there was a negative relationship between environmental stress and resilience, as suggested by some previous empirical studies...
متن کاملApplicability of Functional Groups Concept in Analysis of Spatiotemporal Vegetation Changes on Manmade Habitats
The immense variety in plant diversity at the species level might explain why it is so difficult to establish strict generalizations in vegetation dynamics. In the last two decades many published research reports have shown that the introduction of the concept of plant functional groups (PEG) into the analysis of vegetation dynamics might be more informative in explaining spatiotemporal changes...
متن کاملGenetic Structuring across Marine Biogeographic Boundaries in Rocky Shore Invertebrates
Biogeography investigates spatial patterns of species distribution. Discontinuities in species distribution are identified as boundaries between biogeographic areas. Do these boundaries affect genetic connectivity? To address this question, a multifactorial hierarchical sampling design, across three of the major marine biogeographic boundaries in the central Mediterranean Sea (Ligurian-Tyrrheni...
متن کاملMicrohabitat use by two rocky shore gastropods in an intertidal sandy substrate with rocky fragments.
Sandy beaches in some areas of the São Sebastião Channel in southeastern Brazil have unremittingly undergone a variety of impacts, including the deposition of rock fragments in the intertidal region. Consequently, these environments support a rich fauna comprising both sandy beach and rocky shore organisms. Two rocky shore gastropods, Tegula viridula and Morula nodulosa, are particularly abunda...
