Index words: Saginaw Bay Phytoplankton Zebra mussels Agglomerative hierarchical clustering Community composition Invasive species The colonization of the zebra mussel (Dreissena polymorpha) in Saginaw Bay dramatically altered the phytoplankton community composition resulting in exclusion of light sensitive species and dominance of species with oligotrophic preferences and light resistance. In 1...

Certain species of marine sponges in the order Dictyoceratida harbor large populations of the cyanobacterial symbiont Oscillatoria spongeliae in the mesohyl (interior) of the sponge. We show that in four of these sponge species (Lamellodysidea herbacea, Lamellodysidea chlorea, Lendenfeldia chondrodes, and Phyllospongia papyracea) from Palau there is a consistent community of alpha-proteobacteri...

Cyanobacteria are prokaryotic, plantlike organisms present in lakes, recreational waters, and reservoirs, and often dominate phytoplankton communities in warm, nutrient-enriched hard waters. A stable water column rich in certain nutrients, especially nitrogen and phosphorus, is associated with favorable environmental conditions that support development of cyanobacterial population maxima or "bl...

The presence of cyanobacteria and their toxins (cyanotoxins) in processed drinking water may pose a health risk to humans and animals. The efficiency of conventional drinking water treatment processes (coagulation, flocculation, rapid sand filtration and disinfection) in removing cyanobacteria and cyanotoxins varies across different countries and depends on the composition of cyanobacteria and ...

The present work focuses on the optimization of energy conversion process and use algal resources for biodiesel production with ultrasound microwave techniques in Oedogonium, Oscillatoria, Ulothrix, Chlorella, Cladophora, Spirogyra first time. fuel properties are investigated to optimize efficiency newly emerging feedstock. study indicates that optimized technique improves lipid extraction (38....
