both climate change and anthropogenic impact are creating a dynamic of continuous changes in ecosystems. while the expected consequences of these changes are global, the occurrence of extreme events and specific environmental problems are usually local or regional phenomenon. in particular, the coastal ecosystems are among the first vulnerable areas to show those changes; in spite of this, are ...

Ecosystem is a unit of ecological community, comprised of biological, physical, and chemical components. The coastal ecosystem is the region of highly dynamic, diverse and productive region on the earth due to the combined action of physical features and bio-chemical processes from land and ocean. Coastal habitats perform a variety of important functions within the ecosystem and support the lif...

In order to maintain the biotic integrity and performance of coastal marine ecosystems affected by human population growth and economic development an ecosystem approach to management is required. This is particularly challenging when, as is the case for many coastal ecosystems, development activities on land, often far removed from the coast, have a major impact on the coastal environment. The...

Natural ecosystems are rarely structurally simple or functionally homogeneous. This is true for the complex coastal region of Magdalena Bay, Baja California Sur, Mexico, where the spatial variability in ecosystem fluxes from the Pacific coastal ocean, eutrophic lagoon, mangroves, and desert were studied. The Sky Arrow 650TCN environmental research aircraft proved to be an effective tool in char...

Sea level rise is a natural global phenomenon which is aggravated by anthropological activities. Severity of the rise varying in different parts of the world but the stress in general is increasingly threatening human development. Sustenance of a few species and their ecosystem depends on the rate and extent of rise. Coastal floods are inundations in coastal areas due to rise in sea water level...

Coastal wetlands can have exceptionally large carbon (C) stocks and their protection and restoration would constitute an effective mitigation strategy to climate change. Inclusion of coastal ecosystems in mitigation strategies requires quantification of carbon stocks in order to calculate emissions or sequestration through time. In this study, we quantified the ecosystem C stocks of coastal wet...

Protecting coastal communities has become increasingly important as their populations grow, resulting in increased demand for engineered shore protection and hardening of over 50% of many urban shorelines. Shoreline hardening is recognized to reduce ecosystem services that coastal populations rely on, but the amount of hardened coastline continues to grow in many ecologically important coastal ...

This paper reviews the present state of knowledge on environmental issues related to bivalve aquaculture, with emphasis on suspended mussel culture. Material reviewed includes Canadian and international studies on the role of wild and cultured bivalve populations in controlling ecosystem-level dynamics. The focus is on identifying potential changes in ecosystem processes (material and energy fl...

sensitive coastal areas are fragile ecosystems affected by geographic features and in the same time settlements were developed around these areas due to their ecological capability. coastal ecosystems due to their countless benefits are very important for protection. hence, this paper attempts to determine the sensitivity of coastal ecosystem to disturbances in hormozgan province. we reviewed 2...

Ecosystem-based management is logistically and politically challenging because ecosystems are inherently complex and management decisions affect a multitude of groups. Coastal ecosystems, which lie at the interface between marine and terrestrial ecosystems and provide an array of ecosystem services to different groups, aptly illustrate these challenges. Successful ecosystem-based management of ...
