Phytoplankton study has become more significant in the Caspian Sea due to the occurrence of ecological events such as algal blooms and the introduction of the invader species(Ctenophore, Mnemiopsis leidyi). A seasonal study was conducted to investigate the features of phytoplankton community one decade after this invasion in the Iranian coast of Caspian Sea during 2009-2010. According to the re...

Generally, phytoplankton exhibits high species diversity and wide range of variation which makes them most successful primary producer in contemporary global oceanographic regimes

Phytoplankton species assemblages in estuaries are connected to those in rivers and marine environments by local hydrodynamics leading to a continuous flow of taxa. This study revealed differential effects of upwelling and river flow on phytoplankton communities observed in 2011 along a salinity gradient from a river reservoir connected to the sea through a ria-marine bay system in A Coruña (NW...

Corsica Island is a sub-basin of the Northwestern Mediterranean Sea, with hydrological features typical of both oligotrophic systems and eutrophic coastal zones. Phytoplankton assemblages in two coastal ecosystems of Corsica (the deep Bay of Calvi and the shallow littoral of Bastia) show contrasting patterns over a one-year cycle. In order to determine what drives these variations, seasonal cha...

Plankton is a fundamental part of the waters, especially in coral reef ecosystems. This study aims to determine abundance and diversity plankton species, both phytoplankton, zooplankton waters Gosong Island, Southwest Aceh. research was conducted May 2021. Samples were collected from 4 sampling points with replications. Phytoplankton consists 51 species which are 3 families, namely Cyanophyceae...

Phytoplankton are the base of the Antarctic food web, sustain the wealth and diversity of life for which Antarctica is renowned, and play a critical role in biogeochemical cycles that mediate global climate. Over the vast expanse of the Southern Ocean (SO), the climate is variously predicted to experience increased warming, strengthening wind, acidification, shallowingmixed layer depths, increa...

From June 2004 to December 2007, samples were weekly collected at a fixed station located at the mouth of Ria de Aveiro (West Iberian Margin). We examined the seasonal and inter-annual fluctuations in composition and community structure of the phytoplankton in relation to the main environmental drivers and assessed the influence of the oceanographic regime, namely changes in frequency and inten...

This exploratory descriptive study with a qualitative approach was aims to analyze the water quality of Batu Dendeng River in West Lombok through phytoplankton community structure. Sampling carried out using purposive sampling method. Water plankton net 20µ mesh sized. Observation and identification at Biology Laboratory FKIP University Mataram binocular microscope. Phytoplankton data analyzed ...

Temporal stability in beta diversity does not guarantee surrogacy or compositional a micro-phytoplankton meta¬community. In this study, we evaluated phytoplankton community organization (i.e., microalgae filtered 20 μm mesh-sized plankton net) highly dynamic subtropical tidal river over three years. Specifically, assessed temporal the spatial of phytoplankton, diatoms’ efficiency as an indicato...

This work was aimed at assessing the effect of crude oil spill on the diversity and abundance of plankton communities of the Njaba River area of the spill. Sampling was carried out in 1999 in nine clusters of stations, three each from upstream, spill-point and downstream transects. Each cluster was made up of three perpendicular sampling points across the river. Standard methods were used in co...
