The use of genus-level determinations and biovolume classes as surrogates to indicate environmental drivers of stream diatom communities in the Brazilian Pampa [PDF]
The demand for low-cost and time-efficient biomonitoring and ecological assessment strategies has increased due to threats to biodiversity. We evaluated the ability of surrogates (genera and biovolume classes) to access information provided by diatom ...

Biovolume calculation for planktonic algae by using 3 dimensional models [PDF]
Biovolume is one of the most important characteristics of planktic organisms which basically influences their functional properties like sinking velocity or tolerance to grazing. Biovolume calculation of microalgae is based on the determination of the geometrical shapes that approximate best the shape of the algal cells.

Comparison of Microphototrophic Communities Living in Different Soil Environments in the High Arctic
The Arctic region undergoes rapid climate change resulting in soil warming with consequent changes in microbial community structure. Therefore, it is important to gain more knowledge on the pioneer photosynthetic microorganisms and their relations to ...

Drivers and food web effects of Gonyostomum semen blooms [PDF]
The flagellate Gonyostomum semen forms dense late-summer blooms in humic lakes and is a nuisance to swimmers because it forms a slimy coat on the skin, causing irritation in sensitive individuals. Increasing occurrence and bloom incidence of G. semen has

Recent progress in the identification and determination of freshwater phytoplankton in the natural environment [PDF]
The biomass of the phytoplankton and its composition is one of the most important factors in water quality control. Determination of the phytoplankton assemblage is usually done by microscopic analysis (Utermöhl's method). Quantitative estimations of the

Réseaux trophiques et production piscicole en étangs fertilisés (Dordogne, France) [PDF]
Des séries de données (physicochimie, plancton, poisson) collectées pendant deux saisons consécutives sur deux groupes d'étangs de pisciculture de Dordogne (Sud-ouest de la France) ont été analysées statistiquement (analyses en composantes principales ...

Disrupted seasonal clockwork in the population dynamics of a freshwater copepod by climate warming [PDF]
Life history responses are expected to accompany climate warming, yet little is known how long-term effects of climate and environmental change affect the seasonal dynamics of planktonic organisms. We used an historical data set from Lake Washington (U.S.
