One of the problems of hydrobotany as relatively young developing scientific discipline is "different interpretations of concepts and terms" [36]. This also applies to "the life form" − the most important concept of ecology, which characterizes habitually expressed system of an organism's adaptation to environment, and in addition to that − community's structure and degree of its impact on environment. The paper gives meanings of the main terms (as interpreted by the authors, who proposed them), associated with concept of the life form in plants.

On the basis of interpreting of retrospective series of satellite images transformation was analyzed of the biotopic structure of wetlands of big lowland reservoir (the Kyiv reservoir, Ukraine). It was shown that process of the landscapes' transformation consists in redistribution of areas among different types of biotopes and secondary floodplain forming.

A total of 24 species and one variety of diatoms (Centrophyceae) of nine genera dominating in phytoplankton of the eutrophic and heavily polluted Klyaz'ma River was revealed during the period of investigations. Species of the genus Stephanodiscus dominated among representatives of this class, which is typical to the tributaries of the Volga River and its reservoirs. The composition of this group of Centrophyceae depends on the environmental conditions typical to contaminated plain watercourses of the temperate zone with natural hydrological regime. In this case, the degree and dynamics of Centrophyceae quantitative development are typical to the rivers with the catchment area subjected to anthropogenic load, which receives large amounts of sewage with a high content of nutrients and organic matter.

Information on the first record of Ranatra linearis (Hemiptera) at the value of salinity of 110 g/L is given in the paper. Mass development of predators of the family Corixidae was observed at salinity of 100−120 g/L in hypersaline water bodies of the Kerch Peninsula (the Crimea). A brief review on the distribution of Hemiptera in hypersaline water bodies of the world, and also on their ecological role, is given in the paper.

Paper deals with conceptual provisions, which can be used as a basis for development of the main directions of hydrobiological monitoring of the techno-ecosystems of the energetic enterprises. The scope of biological monitoring, list of biological objects of monitoring, controlled parameters, periodicity and principles of the monitoring sites location were discussed. Connection of tasks of the hydrobiological monitoring of the techno-ecosystems with provisions of the EU Water Framework Directive was considered.

forms of occurrence
The procedure of two-step preparation of the samples of suspended matter and bottom sediments is given in the paper. The first step includes "wet combustion" of suspended matter in the mixture of the concentrated sulfuric and nitric acids, whereas the second step − hydrothermal treatment of the non-decomposed residue of suspended matter in the steel autoclave with teflon crucible in the alkaline medium (3.2 Mol/L NaOH) at 230°C for 4.5−5.0 hours. It has been shown that only some portion of suspended matter, which is unstable and depends on its composition, origin, and character, is decomposed as a result of "wet combustion". At the first step of suspended matter samples preparation, the degree of extraction varies over a wide range. The major portion of such metals as Al, Fe, Cu, Ti, Cd, Pb, Zn, and Ni, and also of phosphorus, is extracted at the step of "wet combustion". It includes chemical elements absorbed on suspended matter and detritus and those registered in the organisms of hydrobionts, which remain on the membranous filter with the openings of 0.40 pm in diameter. The fraction, which is rather readily extracted from the composition of suspended matter in the slightly acidic medium at pH ~ 4.0, is in the composition of this portion of metals. This fraction of chemical elements should be considered as bioavailable for aquatic organisms. At the same time, silicon is registered mainly in the poorly dissolved fraction of suspended matter (94.3−99.9%). It is released only as a result of hydrothermal treatment.
Data on the total content of the studied chemical elements in the composition of suspended matter in some water bodies and on the degree of their extraction on the first and second steps of sample preparation, and also in the slightly acidic medium, are given in the paper.
