“…Normal values of conductivity (300 μS/cm; Table 1) corresponded to those of the USEPA water and high values of conductivity (3000 μS/cm; Table 1) were achieved by adding 1669.4 mg of sodium chloride NaCl (99% minimum, Lot 47H1049, Sigma, Germany) to 1.5 l of USEPA water. These physical and chemical values were chosen to simulate the values of physical and chemical conditions that occur in the aquatic environments susceptible to be invaded by the NZMS, such as endorheic basins, rivers, estuaries or inner seas (Costil et al 2001;Dybdahl and Kane 2005;Moffitt and James 2012;Astel et al 2016). Glass vessels (volume, 0.23 l; height, 6 cm; diameter, 8 cm; control water volume, 0.17 l) were used as experimental units.…”

The New Zealand mudsnail (NZMS) Potamopyrgusantipodarum (Gray, 1843) (Tateidae, Mollusca) is a successful invasive species able to alter the functioning of the invaded ecosystems. However, to arrive and establish in new aquatic ecosystems, this snail must survive to the overland translocation through aerial exposure and must tolerate the new physical and chemical conditions of the recipient ecosystem. In this study, we simulated different conditions for the NZMS invasion by combining two air exposure treatments (0 and 20 h) with different physical and chemical conditions of the rehydration water (low and normal water temperatures and normal and high water conductivities). Mortality, behavior and neonate production were compared across treatments. Air exposure caused a high percentage of mortality but survivors tolerated the subsequent abiotic conditions. Low temperatures and high conductivities altered the behavior of adult snails, increasing significantly their reaction time (i.e. time to start normal movement). This may have negative consequences for the survival of this species under natural conditions. Finally, these conditions did not affect significantly the production of neonates. These results supported that the surviving NZMS to a brief period of air exposure possess the ability to acclimate to contrasting abiotic conditions with a potential establishment of new populations and that survivors can reproduce in different abiotic conditions after an air exposure period.

Zmiany zasolenia i poziomu wody jeziora Jamno wynikające z budowy wrót przeciwsztormowych Changes in Salinity and Water Level of the Lake Jamno Resulting from the Construction of Storm GatesThe aim of the study is to determine changes in salinity and water level of the Lake Jamno, which occurred as a result of the construction of the storm gate. It is very important aspect, as in the case of coastal lakes rather seeks to "open" object on the direct impact of the sea, and not his "closing". Of course there are many examples in the world to create such hydrotechnical building, the aim of which is to prevent the phenomenon of flooding from the sea. Often it is the result of climate change causing an increase in the number of observed extreme phenomena, example of which are the storm gates in the Thames. Therefore, you should always think about the meaning of the creation of such structures and their subsequent impact on the biotic and abiotic environment. Also be sure to with great care to prepare a draft of such a construction that does not cause more losses than benefits. The study consisted primarily of a review of source materials and fieldwork prior to the construction of a storm barrier (2002)(2003)(2004)(2005)(2006)(2007)(2008) and following the construction of the storm barrier (2015). Fieldwork included hydrographic surveys and water sampling for laboratory analysis. The most important source of information on changes following the construction of the storm barrier was the online source: www.hydrowskaz.pl. The website included data on water levels and specific conductivity for Lake Jamno and the Jamno Canal. The main and most readily observable outcome of the construction of a storm barrier has been a change in water quality in Lake Jamno. This is especially true in the case of key indicators related to marine water including conductivity, whose values changed from brackish-water-type to freshwater--type. A second outcome of the construction of the storm barrier was a change in the water level fluctuation range for Lake Jamno. The fluctuation range has now been reduced by 30 to 40 cm.Keywords: Lake Jamno, storm gate, conductivity, salinity, water level WstępStosunki wodne na świecie, w tym obraz sieci hydrograficznej, ulegają stałym i ciągłym zmianom, wynikającym z szeregu procesów naturalnych (zmiany klimatyczne, warunki pogodowe, specyfika rzeźby terenu, budowa geologiczna itd.) oraz oddziaływań antropogenicznych (procesy melioracyjne, zmiany przebiegu koryt rzek i ich obudowa, dopływ zanieczyszczeń, użytkowanie terenu itd.), szczególnie dobrze widocznych w ostatnim dwustuleciu [1].

“…Studies have also shown that freshwaters in the coastal area are characterized by large changes in water chemistry determined by the area's hydrography, hydraulic contact between land and sea, as well as hydrologic regime (Astel et al 2016). According to Cieśliński (2011), the main driver of water quantity and chemistry in this area is the degree of isolation from the sea.…”

The purpose of the paper is to provide some calculations on the current water balance for the Vistula Lagoon, which is exceptionally valuable in terms of biology and hydrology. It is located along the southern coast of the Baltic Sea in both Poland and Russia. In the era of marked climate change, but first and foremost the plans of the Polish side of the cross-cutting of the Vistula Spit, there has been a need to update the balance data of the Vistula Lagoon. In the near future, they may be an excellent comparative material to changes in the proportions of individual water circulation components in the Vistula Lagoon and changes in its entire ecosystem, caused by the implementation of the project. In the literature on the subject, balance sheet data from 50 years ago are used (these data were compiled in the initial part of the study), hence the concept of attempting to update them has appeared. Due to the lack of data from the Russian part of the catchment area, the main emphasis in the work was put on the completion and modernization of the components of the balance sheet of the Polish catchment. A novelty at work is the refinement of the potamical inflow to the Vistula Lagoon with small but numerous streams flowing from the Elbląg Upland, as well as the inflow forced by polder discharges. Climate water balance data are shown based on data available from IMGW in Warsaw and include monthly precipitation totals for the period 1996–2010 obtained at six gauging sites located near the Vistula Lagoon. Evaporation was calculated using Tichomirov’s formula. River water influx was determined based on data available in Kruk (2011), data from IMGW (Pasłęka River) and data from papers Bogdanowicz (2007, 2009) and documents associated with the Program for biological passages in rivers in Warmińsko-Mazurskie Province (2007). Raw data were also obtained from the Office of Water Management in the city of Elbląg for the period 2006–2011. These data covered water flow moving from the polders. Groundwater influx was estimated using values provided by Silicz (1975). The volume of seawater influx was estimated using the data provided by Silicz (1975) and Chubarenko and Chubarenko (2002). The study confirms that water exchange in coastal lagoons is quite complex due to the presence of several different sources of recharge and several different places where water is lost. The complexity of water cycle is enhanced by a complex hydrographic system of lagoon catchments and a complicated system of water exchange with the sea. The total water volume involved in circulation in the Vistula Lagoon is estimated to be 24,225 mln m3 per year. The largest part of the water received by a coastal lagoon comes from the sea. In this case, it is about 77% (18,130 mln m3 per year). In addition, an array of catchment sources yields about 21% of the studied lagoon’s water. Its catchment provides an additional 4,974 mln m3 of water. The Pregolya River produces 55% of the catchment influx. The volume of water forcibly produced by area polders is so small that it does not produce an observable effect on the water balance in the Lagoon (about 0.04% of total influx). The precipitation constitutes 2.3% of the power supply source of the Vistula Lagoon. On the other hand, the Strait of Baltiysk constitutes the main outflow pathway for water exiting the Vistula Lagoon – close to 98% of all outflow (23,694 mln m3). The remaining 2% is lost due to evaporation.
