Discriminating 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 کاملMesozooplankton grazing and primary production: An alternative assessment
In a recent paper in the journal, Calbet (2001) describes the analysis of data on primary production and mesozoo-plankton grazing from a wide variety of marine ecosystems. The somewhat surprising result of Calbet's analysis is that, ''The slope of the log-log relationship between ingestion rates and PP was significantly Ͻ1, indicating a decline of relative importance of mesozooplankton grazing ...
متن کاملComparative analysis of marine ecosystems: international production modelling workshop.
Understanding the drivers that dictate the productivity of marine ecosystems continues to be a globally important issue. A vast literature identifies three main processes that regulate the production dynamics of such ecosystems: biophysical, exploitative and trophodynamic. Exploring the prominence among this 'triad' of drivers, through a synthetic analysis, is critical for understanding how mar...
متن کاملMesozooplankton grazing and primary production: Reply to the comment by Laws
likely, therefore, that allowance for the fixation of organic carbon as both DOC and POC would tend to reduce the ratio of I : PP in oligotrophic versus eutrophic systems. In conclusion, I disagree with Calbet (2001, p. 1828) that ‘‘the relative importance of microand mesozooplankton in the food dynamics of marine ecosystems, as well as the role of mesozooplankton grazing, must be reevaluated.’...
