Opis:: Śródpolne oczka wodne wypełniają całą gamę funkcji ekologicznych, które dopiero od niedawna zaczęto doceniać. Jedną z tych funkcji jest zatrzymywanie różnych form azotu i fosforu, migrujących z agroekosystemów, przez co w pewnym stopniu zabezpieczają one przed zanieczyszczeniem tymi składnikami wody płynące i zgromadzone w większych zbiornikach. Ta swoista rola oczek wodnych, jako pułapki biogenów, jest szczególnie ważna w kontekście potrzeb związanych z procesem wdrażania w Polsce Dyrektywy Azotanowej, Ramowej Dyrektywy Wodnej i Konwencji Helsińskiej. Celem pracy jest zaprezentowanie roli i znaczenia śródpolnych oczek wodnych oraz podobnych im małych akwenów w ochronie jakości innych rodzajów wód powierzchniowych.
Mid-field ponds fill a whole range of ecological functions that have only recently started to be appreciated. One of these functions is the retention of various forms of nitrogen and phosphorus, migrating from agroecosystems, which, to some extent, protect the flowing water and accumulated in larger reservoirs against contamination with these components. This specific role of ponds as a nutrient trap is particularly important in the context of the needs related to the implementation of the Nitrates Directive, the Water Framework Directive and the Helsinki Convention in Poland. The aim of the study is to present the role and importance of mid-field ponds and similar small water bodies in the protection of the quality of other types of surface waters.

Opis:: Crayfish are valuable invertebrates that are constantly in great demand in all corners of the Earth. Breeding crayfish is not only large-scale production as it can also be arranged in small volumes using pools and installations of closed water supply. Cultivation of crayfish generates profit after a certain period of time, if all biotechnological norms of cultivation are considered. Cultivation of crayfish is a rather promising production, in which it is possible to obtain from 200 to 300% of stable profits during 3–4 years old. The article gives an overview of the technology of growing crayfish, taking into account the characteristics of farming in Ukraine. The basic biotechnological stages of the establishment and operation of the economy are determined, calculations of capital expenditures for the establishment of the economy are presented and the profitability of the project for the production of freshwater crayfish is determined. Cultivation of river crayfish makes it possible to obtain environmentally friendly products that can compete on the markets of Ukraine or EU countries. Also, this way of growing crayfish allows getting stocking material for release in natural reservoirs in order to restore the populations of river crayfish.

Opis:: Since ancient times, water was associated with colonization, being one of the main factors determining the localization of both cities and villages. Rivers, streams, water reservoirs were also the element contributing to the attractiveness of the rural landscape. Initially, the function of surface waters in the rural areas was limited to utility and connected with farm production. With time, the surface waters started being used for energy production and for industrial purposes. Proper management of surface waters also contributes to increase retention and reduce the risk of flooding. With time, streams and ponds became being used in mansion parks, which have been the endeavor enriching the composition. Today, rivers and water reservoirs in the villages no longer play such a significant utility and industrial role. Their function changed into mainly decorative and recreational. However, in many places the potential of using the areas adjoining rivers and ponds is not used by the village residents, which result in backfilling small water reservoirs in the villages and closing the visibility of flowing streams.

Opis:: Na obszarach polodowcowych za jeden z elementów determinujących tempo wysychania i zaniku oczek wodnych można uznać położenie danego zbiornika w zróżnicowanym pod względem rzeźby terenu krajobrazie. Celem badań prezentowanych w pracy było określenie ewentualnego wpływu zróżnicowania wzajemnej wysokości zbiorników wodnych na ich wysychanie. Analizą objęto dwa odmienne pod względem genezy i budowy obszary - morenę denną położoną na Równinie Wełtyńskiej oraz obszary sandrów, należące do Pojezierza Myśliborskiego i Równiny Gorzowskiej. Na podstawie danych uzyskanych z map topograficznych stwierdzono, że z istniejących w XIX w. oczek wodnych do końca XX w. na obszarze moreny dennej falistej zanikło 43%, a na obszarach sandrowych - 60%. W przypadkach, gdy różnica poziomów pomiędzy dwoma najbliższymi zbiornikami była większa niż 1 m, zaobserwowano nieznaczną tendencję do zanikania zbiorników leżących powyżej sąsiadującego zbiornika. Dotyczyło to zwłaszcza oczek położonych na obszarach sandrowych.
Location of a small pond in post-glacial landscape of diverse relief is one of the factors determining its drying out and disappearance. The aim of this study was to determine possible effect of altitude differentiation on drying of such ponds. The study involved two areas differing in morphology and origin: an undulate bottom moraine located on Weltyńska Plain and outwash plains located in Myśliborskie Lakeland and Gorzowska Plain (north-west Poland). Basing on data from topographic maps it can be concluded that over 43% of water ponds in moraine areas and 60% of ponds in outwash plains that had existed in the 19th century disappeared till the end of the 20th century If the elevation of the two neighboring small ponds differed by more than 1 m than a slight tendency of faster disappearance of the upper one was noted. This was especially true for ponds located on outwash plains.

Opis:: The main purpose of the paper was to determine the influence of catchment management on the bottom sediments quality of small water reservoirs as well as to determine toxic metal content in rushes. Samples of bottom sediments were collected in winter 2013 year, form 4 sediment layers (0-5, 5-10, 10-20 and 20-30 cm) at three points along the body of water. The 48 samples were collected. Soil material was prepared according to the procedures used in soil science, the analysis was performed for the fraction with a particle diameter of less than 1 mm. Plant samples from single species aggregations were randomly cut from 5 to 10 locations of 20-50 m2 area. From these samples the average composite sample was prepared. The total content of such elements as Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn was determined by atomic absorption spectrometry (using the Thermo Scientific iCE 3000 series spectrometer) after prior digestion in the mixture (5:1) of concentrated acids HNO3 (65%) and HClO4 (60%). Total Hg content was determined by the AMA 254 analyzer. Between the small water reservoirs adjacent to the areas where organic farming is used, and the reservoirs adjacent to the areas with mineral fertilization there are statistically significant differences in the concentrations of such metals as nickel (layers: 0-5, 5-10, 10-20 and 0-30 cm), as well as cobalt, chromium and iron (in a layer 5-10 cm). It has been found that some plants accumulate higher amounts of heavy metals (average values). Based on obtained results it can be stated that rushes actively captures large amounts of elements reaching studied objects and thereby protect the surface water of the reservoirs from contamination.

Opis:: The aim of this research was the analysis of the species composition and planktonic algae biomass in the ponds of Habsburg Park in Żywiec. So far, the urban park ponds have been rarely studied (especially in Poland) in this respect. The analyses of the park ponds water in Żywiec were conducted during the vegetation season in 2016, in monthly intervals. The phytoplankton biomass was calculated by comparing the shape of algae to geometrical figures and based on the chlorophyll a concentrations. The chlorophyll a concentrations and values of the planktonic algae biomass remained at a low level. The species composition showed the dominance of diatoms (i.a. Achnanthes lanceolate (Brébisson ex Kützing) Grun. in Cl. & Grun., Encyonema sp. (Kützing) Krammer). The highest values of the planktonic algae biomass were observed in the summer season. The ponds in the Habsburgs Park in Żywiec have great aesthetic and recreational values and therefore more frequent monitoring is necessary.

Opis:: The main purpose of this work was to determine the degree of negative impact of heavy metals accumulated in the water sediments to aquatic organisms. Samples of sediments were collected in winter 2013, from 4 layers of sediment (0-5, 5-10, 10-20 and 20-30 cm) at three points along the water reservoir. Sediments were prepared for analysis in accordance with the procedures applied in soil science. The analysis was carried out for the fraction with a particle diameter less than 1 mm. The total content of such elements as Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn, was determined by atomic absorption spectrometry (using the Thermo Scientific iCE 3000 series spectrometer) after digestion in a mixture (5:1) of concentrated acid HNO3 (65 %) and HClO4 (60%). The total Hg content was obtained by using the AMA 254 analyzer. Only the lead content in the analyzed samples of bottom sediments exceeded the contamination value given by polish law (the Regulation of the Minister of Environment). According to the classification of PGI samples of sediments are classified mainly as medium polluted sediments (Class II), with the exception of zinc and lead concentrations (Class III). Due to the value of the indicator of sediments ecological risk (Er) for cadmium, the examined sediments from small water reservoirs no. 1 and 2 should be classified as deposits with a higher rate of environmental contamination risk. The sediments from small water reservoirs no. 3 and 4 belong to the class of a much higher index of contamination risk. On the basis of the PER indicator (a degree of potential envi ronmental risk) the sediments from small water reservoirs located within the area of organic farming can be classified as contaminated by heavy metals to a moderate degree. On the other hand, the analyzed sediments of small water reservoirs no. 3 and 4 were classified as deposits with a severe degree of heavy metal contamination. On the basis of the LAW classification one can say that the bottom sediments of examined ponds were classified into different classes depending on the analyzed chemical element.

Opis:: The study aimed at the evaluation of the quality of bottom sediments and evaluation of potential threat to the aquatic environment. Cadmium, cobalt, chromium, copper, nickel, lead, zinc and mercury concentration in the separate layers of the sediments in the pond at Żelisławiec decreased with the depth of bottom sediments. On the other hand, the highest concentrations of the studied elements occurred in the deepest layer of sediments in the pond at Stare Czarnowo. The level of the potential ecological risk (PER) for the sediments of the Żelisławiec pond classifies them as sediments with low quality of the potential ecological risk, whereas the sediments from the pond at Stare Czarnowo are classified as moderate level of the potential ecological risk. In both ponds, the highest I_geo values were reported for zinc and lead.

Opis:: In recent years, a significant growth in the population of the European beaver Castor fiber L., both in Poland and around the world, has been observed. Beavers significantly transform the natural environment around the sites where they occur. Therefore, it is important to accurately recognize the colonization patterns of new territories by the European beaver and to gain knowledge about the longevity of populations in already occupied areas. This applies especially to areas of natural value, including protected areas. Fieldwork carried out in the spring of 2021, provided information on the distribution of the European beaver and number of individuals in the Magura National Park (MNP) in the Beskid Niski, an arboreous mountain range in southern Poland. The collected data were compared with similar mappings conducted in this Park in 1996 and 2010. This allowed us to characterize the change dynamics of the beaver population in the MNP area and to describe the changes in spatial distribution of sites inhabited by beavers. During the period of 1996-2021, the population of the European beaver increased from 23-26 to 64 individuals in the study area, with a maximum of 68 in 2010. Beaver colonization of ever smaller watercourses draining higher-located catchments and a change in the characteristics of beaver-inhabited sites have been observed. The average number of dam structures within one site as well as site length have increased. Furthermore, the dominant dwelling type has changed from burrows and open-water lodges to bank lodges, which combine characteristics of the two former. We estimate that the period when beavers migrated further up along the watercourses in the studied area was in the years 2010-2021.

Opis:: The main goal of the research was to determine the impact of construction, functioning and liquidation of water mills on the hydrographic network of Wadowice and its surroundings. Another indirect purpose was to reconstruct the medieval river network from the period prior to the heyday of milling and indicate the remaining traces of the milling infrastructure. The research was conducted on the basis of analysis of historical sources and archival topographic maps. The origins of development of milling in Wadowice were dependent on the royal privileges. The first of them was issued in the 15th century. The mills in Wadowice were located on rivers Choczenka, Kleczanka and Dąbrówka, as well as on three artificial mill races, but never on river Skawa. The longest mill race began in Świnna Poręba, where it was supplied with water from Skawa. At the foot of Iłowiec, the mill race was supplied from Nawieśnica and Potok Zbywaczowski, whose course was modified. After merging with Dąbrówka, the mill race ran further parallel to Skawa and ultimately flowed to Choczenka. There were between 3 and 5 mills throughout the entire course of the artificial crosscut. Between 1 and 3 mills were situated at the watercourse which supplies the ponds in Wadowice and Tomice. The third mill race, which began in Kleczanka, powered 1 mill and flowed into Skawa after merging with Rokowski Potok. Due to the environmental conditions, the mills in Wadowice did not require construction of ponds. The mills in Wadowice were located on the basis of economic conditions. The natural conditions were not favourable for the functioning of hydraulic machines, which forced the construction and maintenance of artificial riverbeds. Water milling was subsequently liquidated due to the development of steam mills, and ultimately electric mills. In consequence of the decline of water mills, the maintenance works on mill races were abandoned. Some of the watercourses were backfilled, others were transformed into drainage ditches, whereas the mills in the town were included in the sewerage system. The shape of the former river network of Wadowice is now only reflected by few fragments of certain creeks.
