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 کاملEarly Cenozoic Differentiation of Polar Marine Faunas
The widespread assumption that the origin of polar marine faunas is linked to the onset of major global cooling in the Late Eocene-Early Oligocene is being increasingly challenged. The Antarctic fossil record in particular is suggesting that some modern Southern Ocean taxa may have Early Eocene or even Paleocene origins, i.e. well within the Early Cenozoic greenhouse world. A global analysis of...
متن کاملMarine Invertebrates: Communities at Risk
Our definition of the word 'animal' centers on vertebrates, yet 99% of the animals on the planet are invertebrates, about which we know little. In addition, although the Census of Marine Life (COML.org) has recently conducted an extensive audit of marine ecosystems, we still do not understand much about the animals of the seas. Surveys of the best-known ecosystems, in which invertebrate populat...
متن کامل21 Polar and ice-edge marine systems
Cold, seasonal and dominated by ice, the two polar regions are similar in many ways. Oceanographically, however, they are very different. The Arctic is a deep basin surrounded almost completely by extensive shallow continental shelves and continental land masses. Large river systems (Chapter 2) discharge significant volumes of fresh water and sediment into the Arctic basin, some of them carryin...
