Storms are one of the main causes coastal erosion, causing substantial property and infrastructure losses in communities. Coastal erosion is particularly damaging underrepresented communities that unable to meet building zoning regulations due limited resources [Lam, 2014]. The United States Geological Survey (USGS) has developed a probabilistic assessment hurricane-induced for sandy coastlines...
The midintertidal zone of temperate rocky coasts is often dominated by mussels that form dense beds and exclude other primary space holders. The rate at which storms remove mussels from their substrate consequently has a controlling influence on intertidal community structure. The rate of disturbance by waves can be predicted mechanistically by comparing the attachment strength of an organism t...
We review the spatial distribution of toxic marine microalgal species and impacts all types harmful algal events (Harmful Algal Blooms, HABs) in Mediterranean Sea (MS), including Black Sea, Marmara, coastal lagoons transitional waters, based on two databases compiled Ocean Biogeographic Information System (OBIS). Eighty-four potentially have been detected MS (2,350 records), which 16 described ...
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...
The coastal zone is a complex environment in which a variety of forcing factors interact causing shoreline evolution. Coastal managers seek to predict coastal evolution and to identify regions vulnerable to erosion. Here, a Bayesian network is developed to identify the primary factors influencing decadal-scale shoreline evolution of European coasts and to reproduce the observed evolution trends...
Over the past several decades, rocky desertification has led to severe ecological problems in karst areas in South China. After a rocky desertification treatment project was completed, the vegetation coverage changed greatly and, consequently, increased the ecology water consumption (approximately equal to the actual evapotranspiration) of the regional vegetation. Thus, it intensified the regio...
Data on species diversity and structure in coralligenous outcrops dominated by Corallium rubrum are lacking. A hierarchical sampling including 3 localities and 9 sites covering more than 400 km of rocky coasts in NW Mediterranean, was designed to characterize the spatial variability of structure, composition and diversity of perennial species inhabiting coralligenous outcrops. We estimated spec...
Light is the fundamental driver of primary productivity in the marine environment. Reduced light availability has the potential to alter the distribution, community composition, and productivity of key benthic primary producers, potentially reducing habitat and energy provision to coastal food webs. We compared the underwater light environment of macroalgal dominated shallow subtidal rocky reef...
