The concept of ecological stoichiometry-the balancing of elemental ratios in ecological interactions-has transformed our thinking about processes in natural systems. Here, this perspective is applied to rocky shore ecosystems to explore the consequences of variation in internal nutrient ratios across two trophic levels. Specifically, I measured the internal concentrations of carbon (C) and nitr...

We examine global patterns of benthic macroinvertebrate biomass and its distribution among functional feeding guilds in marine intertidal cOnmlunities. Variation in ash-free dry biomass was related to physical variables (mean annual air and water temperatures, sediment grain size, intertidal slope, tide range and type, wave height and exposure) by least-squares regression analysis of data for 3...

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...

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...

If the primary goal of artificial reef construction is the creation of additional reef habitat that is comparable to adjacent natural rocky-reef, then performance should be evaluated using simultaneous comparisons with adjacent natural habitats. Using baited remote underwater video (BRUV) fish assemblages on purpose-built estuarine artificial reefs and adjacent natural rocky-reef and sand-flat ...

OBJECTIVE There is no study on the trematode parasites of Lophius piscatorius. The aim of this study is to address the lack of knowledge about the parasites of angler fish from the coasts of Turkish seas. METHODS Frozen individuals of L. piscatorius from the coasts of Izmir were brought to Ataturk University, and their visceral organs were parasitologically investigated. Parasites were fixed ...
