A Serpulidaepolychaetae, Spirobranchuskraussii, was newly recorded in the Persian Gulf, Iran. It is the first record of Serpulidae species in Iran. Serpulidaeforms dense aggregations in rocky shores in Bandar Abbas. This research investigated the biological structure and the effect of temperature on embryonic stages of S. kraussii. Sampling was conducted with a quadrant of 10×10 cm2, in r...

Abstract The intertidal invertebrate community on rocky shores in northern Chile is characterised by a high species richness resulting from the productivity of this ecosystem. present study aims to do first characterisation communities Antofagasta town and surroundings (23°S), using co-occurrence niche-sharing null models, analysis similarities (ANOSIM) nonmetric multidimensional scaling (NMDS)...

Sea stars are some of the largest mobile animals able to live in the harsh flow environment of wave-exposed, rocky intertidal shores. In addition, some species, such as the northeastern Pacific Pisaster ochraceus, are ecologically significant predators in a broad range of environments, from sheltered lagoons to the most wave-exposed shorelines. How they function and survive under such an extrem...

The brown alga Fucus serratus is a key foundation species on rocky intertidal shores of northern Europe. We sampled the same population off the coast of southern Norway in 2000 and 2008, and using 26 microsatellite loci, we estimated the changes in genetic diversity and effective population size (Ne). The unexpectedly low Ne (73-386) and Ne/N ratio (10-3-10-4), in combination with a significant...

Quantifying scale-dependent patterns and linking ecological to environmental variation is required understand mechanisms regulating biodiversity. We conducted a large-scale survey in rocky shores along the SE Brazilian coast examine spatial variability body size density of an intertidal barnacle (Chthamalus bisinuatus) its relationships with benthic oceanographic predictors. Both barnacles show...
