There is a need to increase our knowledge about phytoplankton diversity and distribution in the Iranian waters of the Persian Gulf and the Gulf of Oman. Phytoplankton samples along with environmental parameters of the Northeastern waters of the Gulf of Oman (Gordim Bay towards Gwadar Bay) were collected and recorded prior to summer monsoon (Mid of March 2013). Seven inshore and six offshore sta...

The stoichiometric composition of autotrophs can vary greatly in response to variation in light and nutrient availability, and can mediate ecological processes such as C sequestration, growth of herbivores, and nutrient cycling. We investigated light and nutrient eVects on phytoplankton stoichiometry, employing Wve experiments on intact phytoplankton assemblages from three lakes varying in prod...

Samples were collected monthly at four fixed stations in Mida creek from May 1996 to April 1997, in order to determine the species composition, abundance and diversity of phytoplankton and zooplankton collected with 20and 332-μm mesh size plankton nets respectively. Sampling also included measurement of salinity and temperature. Peaks in phytoplankton abundance occurred in May and January, foll...

In this study frequency and composition of plankton in Shadegan wetland was carried out in 5 stations during 2007-2008. Genus qualitative identification and their composition and quantitative frequency aspect were studied (for phytoplankton chlorophyll a). Frequency of total 42 genus phytoplankton in 4 classes Bacilariophyceae (Diatom), Cyanophyceae, Chlorophyceae and Dinophyceae are 69.4, 22.2...

background and objectives: phytoplanktons are organisms with a very high diversities and global distribution in different habitats. the high distribution of phytoplankton is due to ecological flexibility and their ability to tolerate different climatic conditions and environmental stress. phytoplankton is the most sensitive biological indicators of water resources. the purpose of this study was...

A previous multiyear study observed correlations between bacterioplankton community composition (BCC) and abundance and the dynamics of phytoplankton populations and bacterivorous grazers in a humic lake. These observations generated hypotheses about the importance of trophic interactions (both top-down and bottom-up) for structuring bacterial communities in this lake, which were tested using t...

The elemental composition of phytoplankton is a fusion of the evolutionary history of the host and plastid, resulting in differences in genetic constraints and selection pressures associated with environmental conditions. The evolutionary inheritance hypothesis predicts similarities in elemental composition within related taxonomic lineages of phytoplankton. To test this hypothesis, we measured...

The elemental composition of particulate organic matter in the surface ocean significantly affects the efficiency of the ocean’s store of carbon. Though the elemental composition of primary producers is an important factor, recent observations from the western North Atlantic Ocean revealed that carbon-to-nitrogen ratios (C:N) of phytoplankton were significantly higher than the relatively homeos...

1. In an attempt to discern long-term regional patterns in phytoplankton community composition we analysed data from five deep peri-alpine lake basins that have been included in long-term monitoring programmes since the beginning of the 1970s. Local management measures have led to synchronous declines in phosphorus concentrations by more than 50% in all four lakes. Their trophic state now range...
