Monitoring rocky shores

Effects of eutrophication, grazing, and algal blooms on rocky shores

Eutrophication can profoundly change rocky shore communities. These changes often cause the replacement of perennial, canopy-forming algae such as Fucus spp. with annual, bloom-forming algae such as Enteromorpha spp. Grazing, however, can counteract eutrophication by eliminating the annual algae’s susceptible recruits. We examine these generalizations across large scales. We use replicated ‘‘bi...

Whole-Community Facilitation Regulates Biodiversity on Patagonian Rocky Shores

BACKGROUND Understanding the factors that generate and maintain biodiversity is a central goal in ecology. While positive species interactions (i.e., facilitation) have historically been underemphasized in ecological research, they are increasingly recognized as playing important roles in the evolution and maintenance of biodiversity. Dominant habitat-forming species (foundation species) buffer...

Predation by Crabs on Rocky Shores in North-east Atlantic

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...

The Molecular Identification of four Species of Gastropoda on Rocky Shores of the Persian Gulf

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...
