Opis:
Results of the analysis proved that the net primary productivity has a strong connection with the solar insolation. The length of daylight and the level of solar radiation are the driving forces behind changes in growth of primary products, as floral forms are among the first indicators of changes in ecosystems due to global warming. The group of climatic components that have a moderate connection with the bioproductivity of ecosystems of the Polissya are derivatives of bioclimatic indicators related to air temperature, including annual temperature, seasonality, minimum temperature of the coldest month, and the average temperature of the coldest quarter. Seasonality and the annual variation of temperature affect bioproductive processes inversely: the productivity decreases with the increased temperature range between the warmest and the coldest periods of the year and in the middle of quarters.

Opis:
The fauna of helminths of hydrophilic birds was subject of many works in Ukraine. But the most of investigators dealt with helminth fauna of waterfowls in general. And only few works were dedicated to the parasitic nematodes. There are registered 81 species of helminths on Ukraine and 36 species of nematode of hydrophilic bird for Polissya (23 species for Belarus. 15 for Poland and 18 for Ukraine). As well it was compared lists of parts of Polissya between itself. The comprehension of the parasitic nematodes from different part of Polissya showed that 6 species of nematodes are common for whole Polissya: Eucoleus contortus, Amidostomum anseris, Echinuria uncinata, Porrocaecum crassum, Porrocaecum semiteres and Tetrameres fissispina. Further studies are necessary to increase our knowledge on biodiversity of the parasitic nematodes in waterfowls and clear up their taxonomic status.

Opis:
In the humid conditions, the most common ground forms are the ferruginous ones: ferum concretions, marsh ore, ocher spots, etc. Mollic gley soils are widely spread along the periphery of marshes and are formed under the influence of mollic and gley processes on various soil-forming rocks under conditions of sporadically pulsating water regime and excessive moisture under the meadow and swamp biocenoses. The ferrum concretions are characteristic of all genetic horizons of mollic gley soils, except for the soil-forming rock, and their content ranges from 3.3% in the mollic to 47.1% in the lower transitional horizon. The gross iron content in the fine mollic gley soils, as well as in the ferrum concretions forms, increases with depth, and the maximum values are characteristic of the lower transition horizon. The lowest values of the gross iron content are characteristic of the fine soil-forming rock (16.0 mg / 100 g soil) and the mollic soil (66.4 mg / 100 g soil). It was established that the gross chemical content of the ferrum concretions forms is dominated by the iron oxides with the highest content in the ferrum concretions of the mollic soils (48.75%). Also the ferrum concretions forms of iron are characterized by a rather high content of aluminum oxides (5.59–7.92%). The highest values of the accumulation coefficient are character- istic of the iron oxide (Kx = 7.21–2.58), which confirms the hypothesis of the dominant role of its compounds in the formation of the ferrum concretions forms.

Opis:
Investigation results of the gross chemical composition of Malyi Polissya Rendzinas (Rendzic Leptosols) and its transformation under the influence of deflation have been revealed. The oxides percentage in soils, their distribution in the profile have been described, and differentiation soil profile indices have been calculated. The changes in Rendzinas gross chemical composition due to the detection process of deflation have been analyzed.
