Planktons are floating microscopic organisms that are confirmed as the primary producers and initial transporters of carbon to the higher levels of food webs. Moreover, planktons have an special importance and status in the habitat of aquatic ecosystems and therefore, their population dynamic assessment is essential in the study of these ecosystems. An extensive range of physical factors viz. n...
Deep sea water (DSW) commonly refers to a body of seawater that is pumped up from a depth of over 200 m. It is usually associated with the following characteristics: low temperature, high purity, and being rich with nutrients, namely, beneficial elements, which include magnesium, calcium, potassium, chromium, selenium, zinc, and vanadium. Less photosynthesis of plant planktons, consumption of n...
A recent study (2021) of biodiversity in Katobo dam pond, western part the Albertine Rift, middle flats Mitumba Mountains chain Uvira territory, revealed presence 20 genera phytoplankton representing 10 families; 5 zooplankton 3 15 species macro invertebrates grouped into 13 families and; two introduced Cichlid fish genera. Planktonic and benthic macro-invertebrate are less diversified compared...
Recently, a "Brownian bugs" model has been proposed as a possible explanation for the clustering of organisms such as planktons [W.R. Young, A.J. Roberts, and G. Stuhne, Nature (London) 412, 328 (2001)]. In this model, diffusing organisms die and give birth with equal probabilities and are independent of each other. The clustering phenomenon is due to the discreteness of birth and death events ...
In the present study, total thirty planktonic members from four sampling sites of selected research area in which, twelve phytoplanktons and eighteen zooplanktons each under different groups namely (Chlorophyceae, Bacillariophyceae, Cyanophyceae, Euglenophyceae) (Protozoans, Rotiferans, Cladocerans, Copepods) were recorded respectively. Among all phytoplanktonic groups, Chlorophyceae was domina...
