Nutrients and carbon play important roles in algal bloom development. However, nutrients interactions the period of spring are not well understood. The aim this study is to explore covering an urban Jinsha Bay (JSB) coastal water Zhanjiang (South China Sea) using situ multidiscipline observation. results showed that average concentration total nitrogen (TN), phosphorus (TP), dissolved silicon (...

The objective of this study was to record and describe the morphological changes and the ingestion mechanisms of Frontonia leucas (Ehrenberg, 1833) according to the food type and to relate the food ingested with the different environmental conditions in a lotic system, namely São Pedro stream, located in the municipality of Juiz de Fora, Minas Gerais, Brazil. We sampled three points on a monthl...

The invasiveness of algal species can be facilitated by chemo-ecological traits that allow the establishment of invasive species in a highly competitive environment. Anti-bacterial, anti-quorum sensing, anti-diatom and anti-larval properties of the invasive brown macroalga Sargassum muticum and three native Sargassum species from Oman waters were compared in laboratory and field experiments to ...

We assessed the response of phytoplankton communities in aquatic microcosms to single applications of liquid creosote. The creosote was applied to 14 microcosms at concentrations ranging from 0.06 to 109 mg/L. Two microcosms served as controls. Phytoplankton samples were collected from each microcosm one week and 1 d before treatment and at 7 and 21 d after treatment. Temporal changes (response...

The desmid green alga Closterium moniliferum belongs to a small number of organisms that form barite (BaSO(4)) or celestite (SrSO(4)) biominerals. The ability to sequester Sr in the presence of an excess of Ca is of considerable interest for the remediation of (90)Sr from the environment and nuclear waste. While most cells dynamically regulate the concentration of the second messenger Ca(2+) in...

Chlorophyll in plant cells is regularly accompanied by other pigments. For many years there has been speculation as to whether the light absorbed by these so called accessory pigments is utilized for photosynthesis. Engelmann's skillful experiments (1883) on algae of various colors, with motile bacteria as an indicator of photosynthetic activity, have been the basis of a general belief that the...

Tiffany, M.A., M.R. González, B.K. Swan, K.M. Reifel, J.M. Watts and S.H. Hurlbert. 2007. Phytoplankton dynamics in the Salton Sea, California, 1997-1999. Lake Reserv. Manage. 23:582-605. The dynamics of phytoplankton populations in the Salton Sea were studied over the 3-year period 1997-1999. Dinoflagellates were important components, often contributing over 80% of the total biovolume of cells...
