61 The content of chlorophyll a is frequently used as an index of the phytoplankton biomass. However, the relationship between these parameters is complex, because the content of chlorophyll ( C ch ) per biomass unit ( β = C ch / B ) considerably varies depending on the factors of environment. β may vary from 0.1 to 9.7% for waters of different types [1–6].(More)
The effect of mineral particulate matter on the population of bacterioplankton, its aggregation, and productive characteristics was studied in model experiments with different concentrations of particulate kaolin and the same concentration of organic substance (sodium humate). It was found that the presence of mineral particulate matter stimulated the(More)
It has been shown [1, 2] that the surface area of aquatic plants and animals plays an important role in their metabolism. This is particularly true for algae, because they only interact with their environment through their external surface. A considerable amount of data has been published on the functional morphology of macrophytic algae [3–5]. According to(More)
The functional characteristics of bacterioplankton have been studied with reference to its aggregation in water bodies of different types. Several methods were used for calculation of the total numbers of bacteria and proportion of aggregated cells. Analysis of the experimental data has shown a relationship between the functional characteristics of(More)
Some characteristics of bacterioplankton--generation time, daily (P) and specific (P/B) bacterioplankton production, and bacterial metabolic coefficient K2--in the loess-containing Lake Khanka were determined using five modifications of the bacterial-count procedure with the fluorescent dyes fluorescamin and erythrosin. Experiments showed that the(More)
The effect was determined of organo-mineral detritus (OMD), one of the components of suspended mineral matter in aquatic ecosystems, on the production characteristics of bacterioplankton (bacterial production P b and destruction of organic matter R b, as well as bacterial growth efficiency BGE). The relation was determined between these parameters and the(More)
The dependence of the functional characteristics of bacterioplankton from the loess of Lake Khanka on the pore size of filtering materials was investigated. Soluble organic matter (SOM), bacteria, and bacterial consumers adsorbed on particles suspended in the lake water were found to filter differently depending on the pore size of the filtering material.(More)
