The importance and protection of mangrove ecosystems has been recognized in Brazilian Federal law since 1965. Being protected in law, however, has not always guaranteed their protection in practice. Mangroves are found in coastal and estuarine locations, which are prime real estate for the growth of cities, ports and other economic activities important for Brazilian development. In this mini-re...

Abiotic processes of nitrogen (N) are suggested to contribute nitrous oxide (N2O) production; however, the important role these in N2O emissions is invariably ignored. This review synthesized main abiotic hydroxylamine and nitrite associated biogeochemical controls estuarine coastal ecosystems. availably detected environments. The more production than environments, suggesting that plays an prod...

Introduction Estuarine ecosystems are under high anthropogenic pressure and receive a wide Q7 variety of contaminants, including metals. They can remain trapped in estuarine sediments at concentrations for long periods but eventually they be released to the overlying water become toxic resident benthic biota. As consequence, biomonitoring programs surveying health status estuaries coastal areas...

Population growth and the associated transformation of landscapes is a major management challenge for coastal ecosystems. Coastal conservation should be guided by social, cultural, economic, ecological objectives, but integrative decision support tools appropriate complex ecosystems remain underutilized. Evaluating alternative policies objectives that span interconnected terrestrial, freshwater...

Water resources development for human needs has come at a significant cost to the natural functioning of aquatic and riparian ecosystems in the United States and around the world. The construction of hundreds of thousands of dams nationally and globally and the extensive human transformation of land cover have greatly modified the magnitude, timing, and duration of river flows that have histori...

Estuaries significantly impact the global carbon cycle by regulating the exchange of organic matter, primarily in the form of dissolved organic carbon (DOC), between terrestrial and marine carbon pools. Estuarine DOC dynamics are complex as tides and other hydrological and climatic drivers can affect carbon fluxes on short and long time scales. While estuarine and coastal DOC dynamics have been...

Maintaining optimal visual performance is a difficult task in photodynamic coastal and estuarine waters because of the unavoidable tradeoffs between luminous sensitivity and spatial and temporal resolution, yet the visual systems of coastal piscivores remain understudied despite differences in their ecomorphology and microhabitat use. We therefore used electroretinographic techniques to describ...

Synopsis. Non-indigenous species (NIS) are increasingly conspicuous in marine and estuarine habitats throughout the world, as the number, variety, and effects of these species continue to accrue. Most of these NIS invasions result from anthropogenic dispersal. Although the relative importance of different dispersal mechanisms varies both spatially and temporally, the global movement of ballast ...
