The surface water resources of Belarus for the period 1956-2015 were specified. The redistribution of water resources in the basins of the main rivers and administrative regions was investigated. The refined map of the Belarusian river runoff has been built. Runoff forecasts for 11 rivers in the Neman River basin for two scenarios of A1B and B1 climate change were done. The results of forecasting...
The paper presents studies on level hydrolytic activity of extracellular enzymes in the surface microlayer and subsurface water in the coastal lake Dołgie Wielkie. The ranking order of the potential enzyme activity rates in the studied water layers was as follows: aminopeptidase > lipase > α-glucosidase > β-glucosidase. The level of activity of all studied hydrolases was higher in the surface...
The aim of our study was to determine changes in some biochemical indices (alanine (ALT) and aspartate aminotransferase (AST), lactate dehydrogenase (LDH)) as well as lactate and pyruvate level in the blood of horses exercised in recreational horseback riding from Pomeranian regions during a training session. Measurement of values of liver biomarkers (AST, ALT) and muscle damage indicator (LDH), followed...
Field research was conducted in the years 2015-2018 in the Kozinka River valley in Central Pomerania. The purpose of the work was to characterize the stand of Platanthera chlorantha, a species protected by law and listed among species endangered with extinction in Gdańsk Pomerania, Western Pomerania and Greater Poland. The edaphic and phytocoenotic conditions in which greater butterfly-orchid found...
Quantitative indices of herring infestation in Sakhalin waters reveal a high infection rate of fish in the basin of the Sea of Okhotsk, off the east coast of the island. Moreover, in certain years almost 100% of herring were infested. The so-called local populations as well as widely migrating Sakhalin Hokkaido herring are confined to the area of this waterbody. In the basin of the Sea of Japan, off...
This paper shows the results of a survey in which the environmental awareness of the inhabitants of one of the local government units of the Pomeranian Voivodeship – Słupsk County was examined. The aim of the study was to determine the state of the inhabitants knowledge in the field of environmental degradation, and to identify the local community opinion on proecological activities of the local government...
The paper presents the analysis of thermal conditions of coastal Lake Jamno. The long observation series (1971-2013) for the course of surface water temperature suggests its considerable warming (0.28°C∙dec-1). In the monthly cycle, an increase in surface water temperature is observed in all cases except for the winter period (December, January, February). Water was heated the fastest in April (0...
Przedmiotem opracowania były zmiany użytkowania gruntów w ciągu ostatnich 400 lat. Badania objęły obszar, zasięg którego wyznaczają zlewnie trzech lewobrzeżnych dopływów Wieprzy oraz jej zlewni bezpośrednich. Stwierdzono, że na badanym terenie granica las – obszary nieleśne ustaliła się już w średniowieczu, a późniejsze zmiany jej przebiegu miały charakter ewolucyjny. Do połowy XIX wieku był widoczny...
Potential capability of heterotrophic bacteria to hydrolytic degradation different organic macromolecules in three water layers in the marine channel were determined. In studied channel hydrolysed proteins and lipids. The heterotrophic microflora decomposition chitin were represented by the least abundant group of these organisms. The highest number of bacteria hydrolyzing tested organic macromolecules...
The erythrocytes could be considered as a valuable model in studying the cytotoxic effect of environmental xenobiotics owing to its particular structure and the important components of their plasma membrane especially lipids and proteins. The aim of our study was to investigate the erythrocyte hemolytic activity of mute swan (Cygnus olor) from Baltic coastal region in two points, i.e. Sopot and Gdynia...
