Depth-stratified community zonation patterns on Gulf of Alaska rocky shores
نویسندگان
چکیده
Zonation patterns along elevation and depth gradients are common in rocky intertidal and subtidal ecosystems (Underwood 1985; Foster & Schiel 1985; Hawkins et al. 1992; Bertness et al. 2006; and many others) and universal patterns in taxon composition, richness and abundance have been suggested (e.g. Stephenson & Stephenson

The study of seaweeds biomass from intertidal rocky shores of Qeshm Island, Persian Gulf
Rocky shores are one of the most important habitats of marine environment in coastal areas. They host marine organisms including seaweeds because of existence of strong and stable substrate for their growths. Intertidal rocky shores are a prominent feature on coastal areas of Qeshm Island located at the northern part of Strait of Hormuz. In order to study biomass of seaweeds on rocky intertidal...

In this study molecular identification of four species of Gastropoda have been studied based on mitochondrial genes, COI and 16S rRNA in the present work for the first time in the northern rocky coastal zones of Persian Gulf during years 2013 and 2014. Planaxis sulcatus، Cerithidea cingulata، Siphonaria savignyi and Onchidium peronii Identified. After morphological identification, DNA extractio...
متن کاملLarge-Scale Spatial Distribution Patterns of Gastropod Assemblages in Rocky Shores
Gastropod assemblages from nearshore rocky habitats were studied over large spatial scales to (1) describe broad-scale patterns in assemblage composition, including patterns by feeding modes, (2) identify latitudinal pattern of biodiversity, i.e., richness and abundance of gastropods and/or regional hotspots, and (3) identify potential environmental and anthropogenic drivers of these assemblage...
متن کاملDiversity and distribution of True Crabs (Brachyura) from intertidal rocky shores of Qeshm Island, Persian Gulf
Rocky shores are one of the most important habitats of marine environment in coastal areas. This study was done in 2010-2011 to investigate the diversity of true crabs in intertidal rocky shores of Qeshm island. Samples were collected from intertidal zones during the low-tide at 5 stations. The specimens were fixed in 70% Etanol and transferred to laboratory for identification. Altogether, 15 c...
متن کاملEmerging patterns of species richness, diversity, population density, and distribution in the skates (Rajidae) of Alaska
Abstrac t —Six years of bottomtrawl survey data, including over 6000 trawls covering over 200 km2 of bottom area throughout Alaska’s subarctic marine waters, were analyzed for patterns in species richness, diversity, density, and distribution of skates. The Bering Sea continental shelf and slope, Aleutian Islands, and Gulf of Alaska regions were stratified by geographic subregion and depth. Spe...
