Their depth usually does not exceed 3 meters

These habitats are generally muds and roots in mangrove forests, in shore sands and organic-rich mud/silt less thanT0070907 overhanging indigenous Hibiscus tiliaceus,in Paspalum vaginatum salt grass marshes, and in some sand and seashore rock.Fringing reefs are positioned together the shores of the outer bays and are also existing as patches alongside the encompassing coastline. Their depth usually does not exceed 3 meters. The coral assemblage is characterized by Synarea, Psammocora, Montipora and Acropora. Algal vegetation in the bay is dominated by Halimeda, Padina, Microdictyon, Caulerpa, Turbinaria and Porolithon. The composition of sediments toward the outer bay and the coastal fringing reefs may differ in basic from site to website by raises from muddy and silty sediments to sandy and coarse-grained carbonaceous sand and rubble together the coastline.The reef barrier is up to four hundred meters wide, shaped by a shallow reef flat and bordered by a reef crest. The outer reef slope includes furrowed platforms, buttresses and valleys and downward sloping platforms to incredibly deep waters. Acropora, Montipora, and Pocillopora corals are among the dominant genera in the fore-reef places. Sediments comprise coral rubble, and coarse detrital sand that accumulates in furrows and valley bottoms. The base then drops steeply to the ocean flooring .Tides at Moorea are semi-diurnal with a optimum selection of <0.4 m. Current velocities are generally low but may reach up to 3.5 km/h in the channels intersecting the passes. Lagoon water temperature is around 27°C with variations of up to 5°C. Waters that cross the reef barrier into the lagoon flows back through the passes and channels into the open ocean. The average residence time for waters in this system has been estimated to be around 6 hours. Being located in the middle of an ocean and far from continental runoff, the waters surrounding Moorea are oligotrophic, except within the innermost bays where occasional runoff from the island and sewage disposal eutrophicate Moorea’s pristine waters. Rarely, storms push seawater into the lagoon sufficient to flood the mangrove, marshes, and other near shore habitats and human infrastructure. These conditions do not last for more than a few days but may serve to distribute organisms to new locations within the lagoon.To determine the structure in the foraminiferal data set we performed Q-mode clustering techniques with the paired group algorithm using the Bray-Curtis dissimilarity. Cluster analysis is a large-scale analytical procedure to detect structural entities within complex data sets.Dovitinib This entails data mining and patterns discovery. For the cluster analysis, the data was imported into PAST software and analyzed. This technique grouped together samples with similar faunal assemblages and revealed a typology of environmental signatures embedded in a hierarchical dendrogram of foraminiferal assemblages. The full set of samples was subjected to Q-mode cluster analyses and the resulting dendrogram referenced to collection points.For structural refinement a principal component analysis was conducted to identify similarities and differences among foraminiferal assemblages.
