Opis:
Numerous brackish estuarine water bodies are situated in the Polish Baltic Coastal Zone, including smaller and bigger lakes like Sarbsko, Łebsko, Gardno, Wicko, Kopań, Bukowo, Jamno, Resko Przymorskie, Liwia Łuża, Koprowo and Wicko Wielkie. Despite a similar genesis and geomorphological type, these lakes are characterized by different hydrological and hydrochemical conditions, determined by the predominance of terrestrial or marine factors. The origin of Polish coastal lakes and transboudary water bodies is closely related to the history of the Baltic Sea and the last glaciation. Coastal brackish waters have been inhabited by both marine and freshwater organisms.
Pobrzeża Bałtyku obfitują w liczne zbiorniki słonawo-wodne o charakterze estuariów. Należą do nich mniejsze lub większe jeziora: Sarbsko, Łebsko, Gardno, Wicko, Kopań, Bukowo, Jamno, Resko Przymorskie, Liwia Łuża, Koprowo i Wicko Wielkie. Mimo niejednokrotnie podobnej genezy i typu geomorfologicznego, jeziora te charakteryzują się bardzo rożnym układem stosunków hydrologicznych i hydrochemicznych, ukształtowanych w wyniku przewagi czynnika lądowego lub morskiego. Geneza jezior przymorskich i akwenów transgranicznych na polskim wybrzeżu jest ściśle związana z historią Morza Bałtyckiego i zlodowaceniem skandynawskim. Przybałtyckie wody słonawe zostały zasiedlone zarówno przez organizmy pochodzenia morskiego, jak i słodkowodnego.

Opis:
A sediment core, 350 cm long recovered from Młynek Lake, northern of Poland (Warmia and Masuria Region) was analyzed with respect to their content of diatoms and chrysophyte cysts. The aim was to reconstruct the lake water level and climatic changes during the past 2500 years. The recognized diatom assemblages displayed marked floristic changes along the sediment core samples. The main change in diatom composition consists of a shift from an assemblage dominated by benthic Fragilaria sensu lato species through marked intervals to a planktonic one in distinct zones. A high proportion of benthic to plankton taxa has been reported as indicative for a lowering of the lake level with long ice cover in a cold dry climate and a shift from benthic to planktonic diatom taxa reflects arising water level with longest growing season and reduced ice cover on the lake during a warm wet climate. Multivariate statistical analysis included hierarchical ascending clustering distinguished four diatom ecological groups. The analyzed core section was divided into 11 diatom zones according to a distribution of ecological groups and variation in abundance of dominant species supported by 14C data. The results displayed a developmental history of the Młynek Lake that can be divided into 6 main phases of alternating warm wet and cold dry shifts. A distinct dominance of planktonic eutrophic indicator diatoms accompanied by a low abundance of chrysophyte cysts indicates increased lake trophicity and a general trend for the increasing anthropogenic impact.

Opis:
The purpose of the research is to determine the types of course of the coefficients of water stages on pentads on the hydrological year. The research distinguishes five main types and seven subtypes of pentad coefficients of the water stages of lakes in Poland in the average annual cycle. For the analysis, the daily values of water levels of 75 lakes located in the Polish Lowlands in years 1976-2015 were used. The data were obtained from the Institute of Meteorology and Water Management – National Research Institute. For each lake, the coefficient of water stages, for all 73 pentads of the hydrological year, was calculated. Pentadic values of water stage coefficients were the basis for hierarchical grouping of the lakes using Ward’s method. On the basis of dendrogram analysis, 5 main groups of lakes with a different coefficient of water storage in the annual cycle were distinguished – so-called types of the course of pentad coefficient of water stages. The types distinguished differ in the beginning, end and duration of high and low water stages, as well as the variability of the coefficient of water stage in pentads of the hydrological year. Type 1 – with a small range of W coefficient parameter changes throughout the year is characteristic of coastal lakes, in type 2 lakes, high water stages are observed in the summer-autumn period, low stages in spring. In the remaining types, high water stages are usually observed in spring and low in the summer-autumn period.

Opis:
Lobelian lakes are clean, oligotrophic, usually non-flow-through lakes, characterized by a small size and the presence of specific flora (Lobelia dortmanna, Isoëtes lacustris, litorella uniflora, Myriophyllum alterniflorum). This type of lakes has been very rarely studied with regard to water mite fauna living in them. The aim of the present study was to partially fill the considerable existing gap in data by studying the distribution of water mites (Hydrachnidia) in the basin of a lobelian lake (Kąpka Lake) situated in Western Pomerania. The research was conducted during the period from May to August 2011, at monthly intervals. The samples were collected from the depths: 0.1 – 5–6 m. in total, 3271 specimens representing 53 water mite species were collected from the whole Kąpka Lake. The most abundant species included the following (in decreasing order): Limnesia maculata, Hygrobates longipalpis, Lebertia porosa, Forrelia liliacea, Mideopsis orbicularis, Limnesia connata, and Limnochares aquatica. the phenology of the species and their abundance in the Kąpka Lake were characterized by one peak of abundance in the month of July. At every depth of the Kąpka Lake, Limnesia maculata was a dominant species.
Jeziora lobeliowe są czystymi, z reguły nieprzepływowymi jeziorami oligotroficznymi o niewielkiej powierzchni oraz specyficznej florze (Lobelia dortmanna, Isoëtes lacustris, litorella uniflora, Myriophyllum alterniflorum). Jeziora tego typu były bardzo rzadko badane pod kątem charakterystyki zasiedlającej je fauny wodopójek. Celem niniejszego artykułu jest częściowe uzupełnienie tej wyraźnej luki na podstawie badań rozmieszczenia wodopójek (Hydrachnidia) w misie jeziornej jeziora lobeliowego (Kąpka) położonego na Pomorzu zachodnim. Badania przeprowadzono w okresie od maja do sierpnia w 2011 roku w miesięcznych odstępach. Połowów dokonano na głębokościach od 0,1 do 5–6 m. Łącznie na terenie Jeziora Kąpka zebrano 3271 osobników należących do 53 gatunków wodopójek. Do najliczniejszych gatunków należały w kolejności: Limnesia maculata , Hygrobates longipalpis, Lebertia porosa, Forrelia liliacea, Mideopsis orbicularis, Limnesia connata, Limnochares aquatica. Fenologia gatunków i ich liczebności w Jeziorze Kąpka charakteryzowała się jednym szczytem w miesiącu lipcu. na każdej głębokości Jeziora Kąpka gatunkiem dominującym była Limnesia maculata.

Opis:
Habitat studies were conducted on three rare plant communities dominated by Nuphar pumila, Nymphaea candida and Hydrilla verticillata in lakes of north-eastern Poland. The comparison of habitat properties of these three types of phytocoenoses with those of Nuphar lutea common in the area under study was also performed. It was demonstrated that the plant communities studied were ecologically distinct. The habitats of the phytocoenoses of N. pumila differed most significantly from those of the other phytocoenoses. They often inhabited softer waters poor in Mg2+, dissolved SiO2, but rich in total Fe, PO43−, NO3−, and were associated with acidic substrates containing lower levels of Ca2+ and Na+, but greater amounts of total Fe and NO3−. The differences in the habitats of H. verticillata and N. candida phytocoenoses were most pronounced in the case of four properties of water: Na+, K+, Cl−, and Mg+. Their values were lower in waters of the H. verticillata phytocoenoses. The habitats of all the three types of rare phytocoenoses differed considerably from those of N. lutea. The most significant differences were found between the N. lutea and N. pumila phytocoenoses and the smallest differences were between the patches of N. lutea and N. candida. The properties of water were more important in differentiating the habitats of the phytocoenoses studied than the substrate properties. Due to alkalization and increase in water hardness in the lakes studied the stands of N. pumila are among the most threatened. The patches of N. candida and H. verticillata, which occur in waters with a wider range of hardness and tolerating a slight increase in trophy, can still continue to persist in the lakes for a long time.

Opis:
Plastic responses of 10 aquatic plant species from 5 rivers and 5 lakes in NW Poland were examined. Chara fragilis, C. delicatula, Potamogeton pectinatus, P. perfoliatus, P. natans, Spirodela polyrhiza, Hydrocharis morsus-ranae, Salvinia natans, Nymphoides peltata and Juncus bulbosus were the subject of research. In the running water of rivers, rhizophytes were generally bigger and they allocated from 0.6% to 58.6% more biomass for anchoring in the substrate than in stagnant water (ox bow lakes). In both flow variants rhizophytes allocated a similar biomass fraction for generative reproduction. On the other hand, under the influence of water flow pleustophytes reduced the mass of an individual (Spirodela by 25%, Hydrocharis 67%, Salvinia 77%) and emergent structures (p<0.001), and the number of sporangia (p<0.001). In both flow variants the input of biomass to generative reproduction was the same (Salvinia), or it was greater in running water (Hydrocharis; an increase from 4.9±1.3% to 15.1±3.6%). Under the conditions of strong wave action, in comparison with the lack of this environmental factor, Chara delicatula was several times shorter (p<0.001). However, it was also stouter, and as a result it had similar mass. In the areas of wave action the plant allocated 88.8% of its mass for anchoring in the substrate, whereas when there were no waves, only 22.7%.

Opis:
Dreissena polymorpha inhabits about 46.5% of the bottom area in Lake Dabie. It is most abundant in the northern part of the lake and sporadically occurs in its southern part. The average density of the zebra mussel is 891 individuals/m², while its wet weight is 1374 g/ m². In the settled areas the density of the zebra mussel reaches 1734 individuals/ m². There were presently established 7 age-groups from 0 to 6+. The highest number of specimens occurred in the age-groups between 1+ and 3+, while the lowest number - in the groups 0, 5 and 6+. Strong eutrophication and pollution of Lake Dabie on its southern side, combined with sedimentation of the extensive amounts of seston carried in by the Płonia and Regalica rivers, do not create favourable conditions for development of Dreissena. D. polymorpha plays a very positive role in the lake ecosystem through its biofiltrating action, contributing thus to an increase of water clarity and to limitation of phytoplankton development through cumulating nutrients in its biomass. Electrophoretic analysis of 9 enzymatic loci revealed strong polymorphism of the studied population of the zebra mussel: percent of polymorphic loci - 100, mean number of alleles in locus – 3.4, coefficient of expected heterozygosity per locus in the population, HS - 0.335, percentage of separate genotypes - 69%, in this number unique genotypes - 58%. A very strong scattering of the alleles was stated within the entire population. In each aggregation, on average, 90% of the specimens have a separate genotype. Each of the five defined groups of D. polymorpha, representing profiles I-V, respectively, had similar genetic composition. The values of the genetic similarity among the studied groups of the zebra mussel ranged from 0.96 to 0.99.
