Opis:
In spite of modern trends in the development of the eastern Polesye flora, the relict have been preserved in the aquatic ecotopes of Europe, including eastern Polesye. The paper highlights the peculiarities of the distribution in the region of three aquatic Tertiary relics preserved by the Bern Convention. According to the results of a field research, the degree of a modern rarity of the aquatic relict species in eastern Polesye was established, in particular, a very rare species (Aldrovanda vesiculosa), a moderately rare species (Trapa natans) and a relatively rare species (Salvinia natans). The current distribution of these relict species in the region has been positively affected by the increase in the values of maximum temperatures and isotherms of the summer months. A negative impact is made by the abrupt changes in the hydrological regime and the growth of anthropogenic eutrophication of reservoirs. Aldrovanda vesiculosa eliminates with minor changes in living conditions; Salvinia natans is the most tolerant to anthropogenic factors, but shows annual fluctuations in numbers; Trapa natans is stable distributed and has a tendency to expanding of its populations. The relics are the dominants of the Salvinio–Spirodeletum (polyrrhizae), Lemno Utricularietum vulgaris, Spirodelo–Aldrovandetum vesiculosae, Trapetum natantis and Trapо–Nymphoidetum (peltatae) communities.

Opis:
Macrophytes and selected physical-chemical water properties were studied in 17 post-mining lakes of Jeziórko Sulphur Mine – one of the largest borehole sulphur mines in the world. Artificial lakes were constructed in subsidence depressions during the reclamation process of mining fields. They were characterized by high mineralization – conductivity ranged from 723 to 2295 μS/cm. The reaction was near neutral, or more frequently, slightly alkaline. Concentrations of phosphorus and organic matter were low. In the group of hydrophytes, Ceratophyllum demersum, Myriophyllum spicatum, Najas marina, Utricularia vulgaris, Eleocharis acicularis, Potamogeton pectinatus, Potamogeton natans and Potamogeton pusillus were frequently dominant. In several lakes, large macroscopic algae dominated – charophytes forming large, dense Chara meadows. In marsh communities, Phragmites australis was the most expansive. Reclamation process had a positive effect on diversity, some of the species found in the study area are regionally rare, including one species which is threatened in Poland (Najas minor). No alien species were recorded.

Opis:
The recovery or reconstruction of aquatic vegetation has recently been reported as a result of water quality improvement aer anthropogenic eutrophication. The objectives of this study were: to investigate long-term trends in aquatic vegetation abundance in relation to decreasing water fertility and to present new directions in changes of the submerged aquatic vegetation structure, species richness, and biodiversity in Lake Kuźnickie (western Poland) with the perspective of the last 40 years (1978–2018). Lake Kuźnickie is an example of water quality improvement taking place without any additional reclamation measures, except a reduction in nutrient discharge into the lake from its direct catchment. Currently, the study lake represents a mesotrophic status. The Trophy State Index evidenced a decrease in the lake’s fertility compared to previous decades. The water quality improvement manifests in a significant reduction in the total phosphorus concentration. An analysis of the spatial changes in the phytolittoral evidenced a decrease in rush vegetation between 1978 and 2018 by over 2 ha. In the period 1978–2018, the aquatic vegetation structure in Lake Kuźnickie underwent significant reconstruction. Currently, charophytes play a much greater role in the lake compared to the last 40 years, contributing to the maintenance of the lake’s high water quality. Moreover, the endangered charophyte Lychnothamnus barbatus has recovered. Concurrently, however, the biodiversity and species richness of the submerged vegetation has decreased. At present, only four species dominate in the lake, including two charophytes L. barbatus, Nitellopsis obtusa, and two vascular plants Ceratophyllum demersum and Myriophyllum spicatum. Over 40 years, Lake Kuźnickie has changed from a eutrophic lake dominated by vascular plants to a mesotrophic lake with a codominant contribution by charophytes. The lake is characterized by good water quality, optimal for the development of aquatic vegetation, especially charophytes.

Opis:
The paper presents results of geobotanical and taxonomic studies on the distribution and habitat requirements of Nymphaea candida in southern Poland. The researches were conducted in southern Poland in 2003-2009, in the provinces of Lower Silesia, Lublin, Małopolska, Opole, Silesian province as well as, in southern parts of Mazowieckie and Lubuskie. Flowers, leaves and fruits of Nymphaea species were collected from 27 locations. Altogether pollens from 73 populations of N. candida and 18 of N. alba from all the researched area were measured. The trophic level of an ecosystem was evaluated according to the results of the total nitrogen, total phosphorus, chlorophyll a, transparency and biological parameters. As the result of the studies of more than 200 water bodies, 57 localities of N. candida were documented within the investigation area. The populations of N. candida occupy mid-forest water bodies and river ox-bow lakes. A significant number of populations was also found in artificial reservoirs - fish ponds. The most suitable habitat conditions for N. candida occur in shallow waters in the shore zone with the amplitude of the water column vary from 0.5 to 2 m. Regarding the trophy level, N. candida occupies different habitats, mainly mesotrophic and also eutrophic with high content of organic matters. Considering the 15 checked morphological parameters, especially the stigma diameter, the number of carpellary teeth, flower and pollen diameters, the found and collected specimens of N. candida significantly differ from N. alba. The study confirms that N. candida ocurrs in whole lowland Poland without any regional distribution gaps. According to the IUCN guidelines to species assessment the data gathered during the presented study do not allow to classify N. candida as a vulnerable species in Poland. Still existing populations for more than 150 years, numerous stable locations, abundant populations, a habitat accessibility, a biotope extent, an ecological amplitude against the trophy level and direct human impacts suggest, that the species should be regarded as a least concern (LC) taxon.

Opis:
Polluted mine waters contain chemical substances, heavy metal ions, solid suspensions, a very low pH, and are discharged into the hydrographic network, often above cross-border levels. Regardless of the aggregation state, the residues of the mining industry affect all components of the environment: soil, water and air. The emphasis in the past on achieving high production levels and neglecting environmental impacts has in the meantime led to the accumulation of serious environmental damage. As a result of the cross-border effect of pollution, environmental problems have overtaken local character, being pursued by local, regional and global stakeholders. The paper aims to find solutions to the use of aquatic vegetation for the treatment of mine acid waters.
Zanieczyszczone wody kopalniane zawierają substancje chemiczne, jony metali ciężkich, zawiesiny stałe, bardzo niskie pH i są odprowadzane do sieci hydrograficznej, często powyżej poziomów transgranicznych. Niezależnie od stanu skupienia pozostałości przemysłu wydobywczego wpływają na wszystkie elementy środowiska: glebę, wodę i powietrze. Nacisk na osiągnięcie wysokich poziomów produkcji i zaniedbanie wpływu na środowisko doprowadził do poważnych szkód w środowisku. W wyniku oddziaływania transgranicznego problemy zanieczyszczenia środowiska przyjęły charakter lokalny, problem zanieczyszczenia jest rozwiązywane przez lokalne, regionalne i globalne zainteresowane strony. Artykuł pokazuje możliwości znalezienia rozwiązań w zakresie wykorzystania roślinności wodnej do oczyszczania kwaśnych wód kopalnianych.

Opis:
This paper discusses the floristic structure, distribution and habitat requirements of a new aquatic syntaxon, Stuckenietum amblyphyllae ass. nova. Patches of the Stuckenietum amblyphyllae association occur in the Pamir Alai Mountains in Middle Asia (Tajikistan). The biotope of this community represent high mountain rivers and ponds at the bottom of glacial river valleys situated at elevations between 1900 and 3800 m. Patches of the Stuckenietum amblyphyllae association are characterised by a clear predominance of the typical species, i.e. Stuckenia amblyphylla, which occupies an aerial extent of between near 40 up to 90% of the surface studied. Patches of the community are poor in species, comprising a maximum of five taxa. Among associated species mainly rush, aquatic, meadow and marsh taxa have been noted. The Stuckenietum amblyphyllae community prefers cold, open, alkaline waters with medium flow-rate, ranging in depth from 15 to 75 cm. It is also, but rarely, found in the mountain ponds. Together with the Stuckenia filiformis community it designates in the Pamir Alai Mountains the upper limit of aquatic vegetation.

Opis:
Klátovské rameno is the lowland slow-flowing groundwater feed eutrophic tributary of the Malý Dunaj River (Danube Plain), where our study of temporal changes of aquatic macrophytes vegetation was realised in 1999 and 2005. For survey of aquatic vascular macrophytes the Kohler’s method (Janauer 2003) was used, which is compliant with European standard EN 14184. Altogether 35 aquatic macrophyte species were recorded during the survey. Nuphar lutea persisted as the most dominant species in 1996 and 2005. Species diversity increased slightly after the nine years: ten species immigrated to the watercourse. The changes in species abundance have shown weak differences, however the abundance of Sparganium emersum has increased markedly. Alien species Elodea canadensis and both S. emersum and Hydrocharis morsus-ranae significantly enlarged their distribution in the stream. The ecological quality of the river, based on the aquatic macrophytes assessment criteria, was slightly impaired after nine years, but still 90% of its studied course has a high or good ecological status.
