It is widely recognised that microhabitats are important for a variety of marine organisms, yet this knowledge has rarely been applied in the construction of engineered structures as a means of enhancing biodiversity or populations of species at risk. Here we examined the influence of microhabitats on the distribution and survival of the exploited limpet Patella candei on natural shores before ...

For their size, barnacles possess the longest penis of any animal (up to eight times their body length). However, as one of few sessile animals to copulate, they face a trade-off between reaching more mates and controlling ever-longer penises in turbulent flow. We observed that penises of an intertidal barnacle (Balanus glandula) from wave-exposed shores were shorter than, stouter than, and mor...

Sea stars are some of the largest mobile animals able to live in the harsh flow environment of wave-exposed, rocky intertidal shores. In addition, some species, such as the northeastern Pacific Pisaster ochraceus, are ecologically significant predators in a broad range of environments, from sheltered lagoons to the most wave-exposed shorelines. How they function and survive under such an extrem...

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...

Understanding the effects of environmental change on the distribution and abundance of strongly interacting organisms, such as intertidal macroalgae and their grazers, needs a thorough knowledge of their underpinning ecological relationships. Control of grazer-plant interactions is bi-directional on northwestern European coasts: grazing by limpets structures populations of macroalgae, while mac...

The presence of diverse biological substrates adds complexity to coastal landscapes and increases the number of ecological niches that can be used by the mobile epifauna. Studies on the influence of structural complexity have focused mainly on algal host species, but there is little information about the influence of intraspecific structural variation on the associated mobile epifauna. In this ...

The article analysis the factors influencing reduction of reservoir useful volume, including formation shores, and proposes method their quantitative calculation. research was provided in South Surkhandarya reservoir. During exploitation reservoir, were assessed morphometric index basin changes a bank due to various influences. presented mathematical, statistical calculations erosion conditions...

to study the population structure of decapods in the intertidal zone of bushehr rocky shores, some random sample collection from four rocky and rubble shores of bushehr were done using a 50×50 quadrates sampling unit, in four successive seasons from autumn 2009 to summer 2010. totally 8 speciesbelonging to 5 family of decapods were identified and counted. in the whole course of sample collectio...
