Increasing the per capita consumption of shrimp in the country needs to examine consumer’s behavior, in this way, a product will be produced according to the interests of the consumption community and the barriers to consumption will be removed in the country. Since the behavior of consumers of one type of food (shrimp) may vary in different regions, assessing this difference will help provide ...

Background: Heavy metals due to their ecological risks and high toxicity to living organisms are considered as one of the most dangerous pollutants. Therefore, the present study was conducted to investigate the level of pollution, toxicity and the ecological risks of heavy metals in the coastal surface sediments of Bushehr province using systematic review. Methods: To conduct this review study,...

Movements of organisms comprise a fundamental aspect of coastal habitat connectivity. Determining the distribution and co-existence of habitat specialists and generalists in shallow-water seascapes leads to a better understanding of the strength of connectivity-driven community patterns in coastal areas. In this study, unbaited Remote Underwater Video (RUV) systems were used to examine habitat ...

The average global sea level was rising through the 20th century as a result of global warming [8, 9, 26]. The Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) estimated that between 1901 and 2010, the mean sea level rate 1.7±0.2 mm/yr and increased to 3.2±0.4 mm/yr between 1993 and 2010, and projected that in 2100 the largest increase in global average sea level ...

Thirty-four grass species were collected for phytolith analysis from a variety of coastal environments in the southeastern USA (Georgia, Florida, and Louisiana), including salt marshes, freshwater/brackish marshes, pine/oak forests, maritime hardwood forests, and sand dunes. Phytoliths produced by these modern grasses include a large diversity of shapes and types. We propose a preliminary relat...

Since coastal tourism is one of the fastest growing sectors of tourism industry, coastal areas have become increasingly vulnerable in case of flooding. Yet, coastal tourism is a seasonal phenomenon, with variations according to climate, holiday seasons and seasonal traditions. Despite its relevance in environmental issues, the effects of seasonal tourism have only scarcely been studied in coast...

The quality of life and economies of coastal communities depend, to a great degree, on the ecological integrity of coastal ecosystems. Paradoxically, as more people are drawn to the coasts, these ecosystems and the services they provide are increasingly stressed by development and human use. Employing the coastal Gulf of Mexico as an example, we explore through three case studies how government...

An analytical model for a coastal boundary current was used to investigate heat and salt budget of exchange flows in the Persian Gulf as a marginal sea. Coastal boundary currents exchange heat and freshwater with the mosphere and the offshore waters. As heat and salinity fluxes caused by air-sea interaction and eddy activities, different temperature and salinity associated with boundary current...
