The amount of fluvial input has important impacts on shelf regions. To understand how the magnitude discharge affects plume ecosystems, particularly organic carbon consumption, data over 10 consecutive summers (2003–2012) were examined in Changjiang River East China Sea. area ranged from approximately 4.90 × 103 km2 to 94.83 and varied proportion freshwater rate. Plankton community respiration ...

Plankton is a massive and phylogenetically diverse group of thousands prokaryotes, protists (unicellular eukaryotic organisms), metazoans (multicellular organisms; Fig. 1). functional diversity at the core various ecological processes, including productivity, carbon cycling sequestration, nutrient (Falkowski 2012), interspecies interactions, food web dynamics structure (D'Alelio et al. 2016). T...

When Victor Hensen deployed the first true plankton net in 1887, he and his colleagues were attempting to answer three fundamental questions: What planktonic organisms are present in the ocean? How many of each type are present? How does the plankton’s composition change over time? Although answering these questions has remained a central goal of oceanographers, the sophisticated tools availabl...

Marine birnavirus (MBVs) infect a wide range of fish and shellfish. Yet their mode of transmission is still unclear. To determine marine plankton serve as a vector for MABVs. The marine birnavirus (MABVs) is a member of Aquabirnavirus and an opportunistic pathogenic form among eukaryotic marine organisms and determine the viral presence in zooplankton as a vector, molecular diagnosis can be use...

I wish to establish whether the plankton is affected by Langmuir circulations (LCs). LCs are wind and wave induced flows in the mixed layer (ML) and comprised of counterrotating, helical cells aligned with the wind. They occur broadly and frequently. While their surface manifestation is relatively well known, their dynamics and relation to the plankton are less well understood. Of particular in...

The remodelling of organelle function is increasingly appreciated as a central driver of eukaryotic biodiversity and evolution. Kinetoplastids including Trypanosoma and Leishmania have evolved specialized peroxisomes, called glycosomes. Glycosomes uniquely contain a glycolytic pathway as well as other enzymes, which underpin the physiological flexibility of these major human pathogens. The sist...

aquatic plants have a major influence upon other aquatic organisms, by altering both water chemistry and spatial structure of the habitat in shallow water bodies. some of them, such as stratiotes aloides l., may suppress algal growth. but how aquatic plants would ultimately influence the heterotrophic community and the aquatic ecosystem as a whole is far from clear. our microcosm-based study de...

Stomach contents of Simulium perflavum Roubaud larvae were analyzed and compared with plankton and periphyton collected in five streams, in Central Amazonia (Manaus and Presidente Figueiredo counties), in Sep./Oct.1996 (dry season) and Feb./Mar. 1997 (rainy season). A total of 1,400 last-instar larvae were dissected; the stomach contents were analyzed using different methods: fresh and after ox...

Eutrophication, often resulting from human activity, is a serious threat to aquatic communities. Theoretical analysis of this phenomenon, based on conceptual mathematical models, leads to controversial predictions known as Rosenzweig's paradox of enrichment. At the same time, field observations demonstrate that real plankton communities exhibit various mechanisms of self-regulation which can bu...
