Context‐dependent functional dispersion across similar ranges of trait space covered by intertidal rocky shore communities
Functional diversity is intimately linked with community assembly processes, but its large-scale patterns of variation are often not well understood. Here, we investigated the spatiotemporal changes in multiple trait dimensions ("trait space") along vertical intertidal environmental stress gradients and across a landscape scale. We predicted that the range of the trait space covered by local as...
متن کاملBiogeographical Boundaries, Functional Group Structure and Diversity of Rocky Shore Communities along the Argentinean Coast
We investigate the extent to which functional structure and spatial variability of intertidal communities coincide with major biogeographical boundaries, areas where extensive compositional changes in the biota are observed over a limited geographic extension. We then investigate whether spatial variation in the biomass of functional groups, over geographic (10's km) and local (10's m) scales, ...
متن کاملSubtidal Rocky Shore Communities of the Azores: Developing a Biotope Survey Method
WALLENSTEIN, F.F.M.M.; NETO, A.I.; ÁLVARO, N.V., and TITTLEY, I., 2008. Subtidal rocky shore communities of the Azores: Developing a biotope survey method. Journal of Coastal Research, 24(1A), 244–249. West Palm Beach (Florida), ISSN 0749-0208. At 23 sites selected randomly around the island of São Miguel (Azores), video records were made at the depths of 5, 10, 15, 20, 25, and 30 m where a roc...
متن کاملMesoscale Variation of Mechanisms Contributing to Stability in Rocky Shore Communities
Environmental fluctuations can generate asynchronous species' fluctuations and community stability, due to compensatory dynamics of species with different environmental tolerances. We tested this hypothesis in intertidal hard-bottom communities of north-central Chile, where a persistent upwelling centre maintains a mosaic in sea surface temperatures (SST) over 10s of kilometres along the shore....
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...
