in this study, the amount of nickel and vanadium elements in the soft tissues of rock oysters (saccostrea cuculata) and sea water from coastal areas of qeshm island, the biggest island of persian gulf located in the south of iran, were measured to evaluate the contamination of the aquatic environment and organisms. following the bioassay, weighing and chemical digestion of the samples, finally...

Macroalgae is a biological key element for the assessment of the ecological status in coastal waters in the frame of the European Water Framework Directive (WFD, 2000/60/EC). Here we propose a methodology for monitoring water quality based on the cartography of littoral and upper-sublittoral rocky-shore communities (CARLIT, in short). With the use of spatial databases, GIS, and available inform...

Habitat fragmentation has been suggested to be responsible for major genetic differentiations in a range of marine organisms. In this study, we combined genetic data and environmental information to unravel the relative role of geography and habitat heterogeneity on patterns of genetic population structure of corkwing wrasse (Symphodus melops), a rocky shore species at the northern limit of its...

ecological classification of the coastal zone, have recently been using the “biotope” as a unit. lexically “biotope” is synonymous with habitat, but with different ecological concepts. various biotopes in 122 km intertidal stretch of the southern coasts of the qeshm island (qeshm city in east to dustaku village in west) in four seasons were identified and mapped out (2009-2010). considering the...

A commonly found red alga of the upper intertidal zone of New Zealand rocky coasts is described for the first time as Pyropia plicata sp. nov. This species has been incorrectly known as Porphyra columbina Mont. (now Pyropia columbina (Mont.) W.A.Nelson) for many years. Pyropia plicata is widespread and common, and it is readily distinguished from other species of bladed Bangiales in New Zealand...

The dogwhelk is a rocky intertidal gastropod of the North Nucella lapillus Atlantic coast. Individual shell color varies. Common colors range between white and brown, with darker dogwhelks being more affected by heat stress than lighter-colored conspecifics. Other reported shell colors are purple, black, mauve, pink, yellow, and orange from UK coasts, red and gray from the Bay of Fundy coast of...

This paper shows that the location of the shoreface bank reefs along the northeastern and eastern coasts of Brazil, in a first order approximation, seem to be controlled by the deficit of sediment in the coastal system. The sediment transport pattern defined by a numerical modeling of wave refraction diagrams, representing circa 2000 km of the northeastern and eastern coasts of Brazil, permitte...

Rocky shorelines are commonly punctuated, with alternating high relief cliffs and incised embayments which host “pocket beaches”. While multiple cases of ancient rocky associated low ravinement surfaces have been documented in the geological record, deposits formed pocket beaches joint-cut coves more rarely described. This poses question “are coastlines their not preserved or they previously ov...
