Antipatharian corals are important structural and complex members of benthic communities inhabiting the Italian seafloor. In this study, distribution black in Italy is reported mapped for first time. This review has permitted identification occurrences such vulnerable marine ecosystems along coasts a bathymetric range 42 m to 790 m. Black appear be most conspicuous widely distributed mesophotic...

In rocky intertidal habitats, the pronounced increase in environmental stress from low to high elevations greatly affects community structure, that is, the combined measure of species identity and their relative abundance. Recent studies have shown that ecological variation also occurs along the coastline at a variety of spatial scales. Little is known, however, on how vertical variation compar...

In this study, the relationship between annual sunspot number (ASN) and annual precipitation totals (APT) has been investigated over the northern coasts of the Persian Gulf and Oman Sea by using two statistical methods: contingency tables and cross-correlation function. Only Bushehr and Jask stations (270 mm and 140 mm mean APT) have long term monthly precipitation records started instrumentall...

Canopy-forming seaweed species of the genus Cystoseira form diverse and productive habitats along temperate rocky coasts of the Mediterranean Sea. Despite numerous studies on the rich macrofauna and flora associated with Cystoseira spp., there is little knowledge about the epiphytic bacteria. We analyzed bacterial populations associated with canopies of Cystoseira compressa, over an annual vege...

Invasive species can affect the function and structure of natural ecological communities, hence understanding and predicting their potential for spreading is a major ecological challenge. Once established in a new region, the spread of invasive species is largely controlled by their dispersal capacity, local environmental conditions and species interactions. The mussel Mytilus galloprovincialis...

Gastropod communities were investigated along two intertidal sandy and rocky shores in Qeshm Island, the northern Persian Gulf, IR Iran to identify the species of the family Cypraeidae. Monthly sampling was undertaken from May 2007 to April 2008 by haphazardly placing eighteen 0.25 m2 quadrates along two 30m wide transects located approximately 300m apart, perpendicular to the sea, in each sand...

Today, rocky monuments are being exposed to different physical, chemical and biological factors and therefore going to be ruined. One of physical destructive factors is growing of fungus and lichens on the rocks. This research aims to make use of silver nano-particles produced through microbial method in order to prevent</e...
