the present study reports the changes in the phytoplankton community structure in taklong island national marine reserve (tinmar), guimaras island, philippines. quantification of pah yielded undetectable results, whereas, primary productivity, phytoplankton density, and diversity values were higher as compared to samples before the oil spill and samples from the reference site. sixty-nine gener...

the zerebar lake is a shallow freshwater lake located in the northwestern iran. the lake is surrounded by three human activities: agriculture, tourism and dam. the present study aimed to investigate (1) which human activity has the greatest impact on eutrophication of the zerebar lake (2) if phytoplankton communities, as the indicator, are correlated with the human activities. water samples wer...

light is never being distributed homogeneously and it forms a gradient over biomass. the unidirectional nature of light gives rise to a vertical gradient of light intensity as a function of depth. the maximum depth of the light zone suitable for phytoplankton photosynthesis is designated as the euphotic depth. this study was designed to test the hypothesis of mixing depth of phytoplankton and i...

under the contemporary scenario of global climate change and increasing coastal eutrophication, baseline studies of phytoplankton diversity and distribution in relation to habitat conditions constitute the first approach to evaluate potential shifts at the base of the food webs. here we present data of phytoplankton species composition and environmental variables in winter 2006 in a temperate e...

Phytoplankton taxa composition of the Caspian Sea were evaluated by using samples collected at 12 stations along the Iranian coast of the Caspian Sea between 1996 and 2010. This study identified 158 phytoplankton species consisted of diatoms (70 species), dinoflagellates (23 species), chlorophytes (29 species), cyanophytes (31 species), and euglenoids (5 species). The dominant species were the...

 Phytoplankton growth and microzooplankton grazing were investigated at one station in the Homa Lagoon from February to January in 2006-2007. Our results showed significant seasonal variations in phytoplankton dynamics. Microzooplankton was mainly composed of dinoflagellates and tintinnid ciliates and nauplii. Microzooplankton grazing increased with increasing of temperature. Grazing rate was ma...

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...
