La dynamique spatio-saisonnière des micro-algues de réservoir d’Adzopé a été analysée à partir d’échantillons collectés mensuellement janvier décembre 2005. Un total 186 taxons rang spécifique et infra identifié. Au niveau spatial, les densités plus élevées sont enregistrées en aval alors que faibles le amont. saisonnier, général, micro-algales maximales lors la grande saison sèche petite pluvi...

Abstract Lotic environments are subjected to the impacts of human activities in an intense way urban regions and one ways assist environmental diagnosis is through knowledge composition bioindicator organisms, including microalgae. The objective this work was qualitatively characterize Chlorophyceae Class Wille, providing descriptions meristic data specimens as well conditions which taxa were r...

In this study, we conducted proof-of-concept research towards the simultaneous treatment of livestock wastewater and generation high-quality biodiesel, through microalgae technology. Both original (OPE) anaerobically-digested (DPE) piggery effluents were investigated for culture microalgae, Desmodesmus sp. EJ8-10. After 14 days’ cultivation, dry biomass from cultivated in OPE increased an initi...

Experiments on side-setting methods were conducted in April-May 2006 using a large-sized longline research vessel (total length 54 m, 450 GT) to examine the applicability of side setting to large distant-water-type Japanese longline vessels. Two sets of line setting equipment were installed at the end and side of the stern deck, and the performances of stern setting and side setting were compar...

S 99 Over time, a population of rotifers had contaminated the Scenedesmus sp. cultures, triggering the production of multicelluar, spinous forms, a typical anti-predator strategy for this genus. It is then concluded that Scenedesmus sp. does exhibit phenotypic plasticity in response to biotic and abiotic changes in the surrounding environment. Additionally, some genetic variation was found in s...

—A new species of ghost shrimp, NeocaUichirus raymanningi, is described based on specimens collected in subtidal habitats in the Gulf of Cariaco, northeastern Venezuela. This new species is most similar to N. rathbunae (Schmitt), but differs from it primarily in having a broadly rounded rostrum, and in the case of males, unique armature of merus and dactylus on the major cheliped. A checklist o...

We revealed abiotic components (extracellular polymeric substances, EPSs) in the periphytic biofilms. Further, effect of microbial community on EPS, and geodistribution patterns ecological functions EPS were studied. In nature, most microorganisms grow as aggregates, flocs, or biofilms [1, 2], held together by a self-produced matrix extracellular substances (EPSs) [3]. Periphytic are typical ex...
