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 Bay of Quinte, a Z-shaped embayment at the northeastern end of Lake Ontario, has a long history of eutrophication problems primarily manifested as spatially extensive algal blooms and predominance of toxic cyanobacteria. The purpose of this study was to identify the structural changes of the phytoplankton community induced by two environmental alterations: point-source phosphorus (P) loadin...

The physico-chemical characteristics, phytoplankton composition and distribution at the East mole area of the Lagos harbour were investigated between January and June, 2012. The physicochemical conditions varied between high brackish and sea water chemistry. Records were Air (26 33 0 C) and Water temperatures (28 31 0 C), Salinity (19.40 30.72 0 /00), Nutrients (Nitrate ≥ 3.11 mg/L; Phosphate ≥...

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...

the early reaction of the plankton communities to environmental changes makes it a useful tool for monitoring the pollution of aquatic environments. lake azili is a small water body, the majority of which is strongly influenced by river ouémé during the floods time. its ecosystem is one of the most important for the country, due to its rich biodiversity, especially that of halieutics. by follow...

Phytoplankton functional diversity plays a key role in structuring the ocean carbon cycle and can be estimated using measurements of phytoplankton functional type (PFT) groupings. Concentrations of 18 phytoplankton pigments were calculated using a linear matrix inversion algorithm, with an average r2 value of 0.70 for all pigments with p-values below the statistical threshold of 0.05. The inver...

The problem of assessing the impact pollution in protected areas prompted us to apply a combined method bioindication and spatial mapping phytoplankton data from six lakes Burabay National Nature Park Northern Kazakhstan. issue monitoring planning was quite acute for this landscape-homogeneous area among Kulunda steppes. Phytoplankton each collected summer season 2019 at total 54 sampling stati...

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...
