A physical-biogeochemical coupling scheme for modeling marine coastal ecosystems
Ecological modeling of dynamic systems such as marine environments may require detailed spatial resolution when the modeled area is greatly influenced by complex physical circulation. Therefore, the simulation of a marine ecosystem must be underlain by a physical model. However, coupling hydrodynamic and biogeochemical models is not straightforward. This paper presents a modeling technique that...
متن کاملDiscriminating mesozooplankton communities in Bushehr marine coastal ecosystems- Persian Gulf
Coastal ecosystems of Bushehr are shallow environments subject to human impacts, including shrimp aquaculture and urban expansion activities. A spatial-temporal study was conducted in order to assess the actual ecological status of the creeks, estuary and marine sites on the basis of their taxonomic composition and density of mesozooplankton. Zooplankton species distribution and abundance data ...

متن کاملArsenic Circulation in Marine Ecosystems
Microbial conversion behavior was investigated with several standard arsenicals. As typical origin of marine micro-organisms, sediments, macro-algae, mollusk intestine and suspended substances were used. The degradation of arsenobetaine was observed with every origin, suggesting the ubiquitous occurrence of arsenobetaine-decomposing microorganisms in marine environment. Especially, the microorg...
متن کاملSpecial issue: nutrient dynamics in coastal ecosystems—linking physical and biological processes
Ecosystems are entities comprising both communities of interacting organisms and physical aspects of the environment in which they live. Healthy coastal ecosystems can be characterised as having high species diversity and high rates of productivity (although there are of course exceptions to this). The growth of primary producers requires adequate light and nutrients. However, when the concentr...
