Top-down and bottom-up community regulation in marine rocky intertidal habitats.
Strong top-down control by consumers has been demonstrated in rocky intertidal communities around the world. In contrast, the role of bottom-up effects (nutrients and productivity), known to have important influences in terrestrial and particularly freshwater ecosystems, is poorly known in marine hard-bottom communities. Recent studies in South Africa, New England, Oregon and New Zealand sugges...

متن کاملEvent-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces
Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...
متن کاملEffects of predation by sea ducks on clam abundance in soft-bottom intertidal habitats
Recent studies have documented strong, top-down predation effects of sea ducks on mussel populations in rocky intertidal communities. However, the impact of these gregarious predators in soft-bottom communities has been largely unexplored. We evaluated effects of predation by wintering surf scoters Melanitta perspicillata and white-winged scoters M. fusca on clam populations in soft-bottom inte...
متن کاملCommunity structure and functioning in intertidal rock pools: effects of pool size and shore height at different successional stages
Rock pools are dynamic and intermittently isolated habitats in the rocky intertidal. They can be used as model systems to provide a more general insight into the ecology of patchy habitats, which are less amenable to experimentation, such as islands and wildlife reserves. In the present study, a range of pools of differing sizes was selected at 2 vertical levels on the shore to assess the impor...
