Markov chain analysis of succession in a rocky subtidal community.
We present a Markov chain model of succession in a rocky subtidal community based on a long-term (1986-1994) study of subtidal invertebrates (14 species) at Ammen Rock Pinnacle in the Gulf of Maine. The model describes successional processes (disturbance, colonization, species persistence, and replacement), the equilibrium (stationary) community, and the rate of convergence. We described succes...
متن کاملCascading Effects of Ocean Acidification in a Rocky Subtidal Community
Temperate marine rocky habitats may be alternatively characterized by well vegetated macroalgal assemblages or barren grounds, as a consequence of direct and indirect human impacts (e.g. overfishing) and grazing pressure by herbivorous organisms. In future scenarios of ocean acidification, calcifying organisms are expected to be less competitive: among these two key elements of the rocky subtid...

متن کاملTrophic linkages across seascapes: subtidal predators limit effective mussel recruitment in rocky intertidal communities
Food-web linkages between habitats across a landscape are known to be important in terrestrial systems. Linkages through the lower (nutrients) and higher (predators) trophic levels are also starting to be recognized across seascapes. Here, we test the potential importance of a subtidalintertidal trophic linkage through predation on mussel recruits by fish in mussel-dominated communities at 2 ti...
متن کاملShading facilitates sessile invertebrate dominance in the rocky subtidal Gulf of Maine.
Dramatic shifts in community composition occur between vertical and horizontal rocky surfaces in subtidal environments worldwide, yet the forces mediating this transition are poorly understood. Vertical rock walls are often covered by lush, diverse communities of sessile suspension-feeding invertebrates, while adjacent horizontal substrates are dominated by algae, or corals in the tropics. Mult...
