Patterns of Spatial Variation of Assemblages Associated with Intertidal Rocky Shores: A Global Perspective
Assemblages associated with intertidal rocky shores were examined for large scale distribution patterns with specific emphasis on identifying latitudinal trends of species richness and taxonomic distinctiveness. Seventy-two sites distributed around the globe were evaluated following the standardized sampling protocol of the Census of Marine Life NaGISA project (www.nagisa.coml.org). There were ...
متن کاملTemporal Variation in Rocky Intertidal Gastropods of the Qeshm Island in the Persian Gulf
Gastropod assemblages were investigated along intertidal rocky shore in the Qeshm Island in the northern Persian Gulf. Monthly sampling was undertaken from May 2007 to April 2008. Environmental factors were also measured in each site. A total of 28 gastropod taxa belonging to 15 families were identified and Cerithiidae was the most abundant family and Cerithium caeruleum was the most abundant...
متن کاملSurfzone hydrodynamics as a key determinant of spatial variation in rocky intertidal communities.
Larvae of intertidal species develop at sea and must return to adult habitats to replenish populations. Similarly, nutrients, detritus and plankton provide important subsidies spurring growth and reproduction of macroalgae and filter-feeding invertebrates that form the foundation of intertidal communities. Together, these factors determine the density and intensity of interactions among communi...
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 کاملBiodiversity of rocky intertidal benthic communities associated with copper mine tailing discharges in northern Chile.
Copper mine tailings have been discharged around the city of Chanaral, in northern Chile, for more than 60 years. This report summarizes a 17-month long monitoring study of species richness and biodiversity at five intertidal sites around the point of the tailing discharge. Total dissolved copper in sites close to the point of discharge varied between 8.72 microg/l and 34.15 microg/l, showing t...
