“…It was broadly documented that the eutrophication process causes several negative ecological consequences, mostly affected by massive phytoplankton and algae blooms, a serious problem in the context of water supply due to its toxicity and impact on human health [4][5][6]. Changes in physico-chemical water properties, such as the decrease in water saturation with oxygen, the increase of water acidification, and the reduction of its transparency [7,8], were also documented as results of eutrophication. In addition, the presence of high nutrient concentrations, especially various nitrogen forms, also has a direct impact on the life-cycles of aquatic organisms in inland waters [9].…”

The influence of landscape on nutrient dynamics in rivers constitutes an important research issue because of its significance with regard to water and land management. In the current study spatial and temporal variability of N-NO3 and P-PO4 concentrations and their landscape dependence was documented in the Świder River catchment in central Poland. From April 2019 to March 2020, water samples were collected from fourteen streams in the monthly timescale and the concentrations of N-NO3 and P-PO4 were correlated with land cover metrics based on the Corine Land Cover 2018 and Sentinel 2 Global Land Cover datasets. It was documented that agricultural lands and forests have a clear seasonal impact on N-NO3 concentrations, whereas the effect of meadows was weak and its direction was dependent on the dataset. The application of buffer zones metrics increased the correlation performance, whereas Euclidean distance scaling improved correlation mainly for forest datasets. The concentration of P-PO4 was not significantly related with land cover metrics, as their dynamics were driven mainly by hydrological conditions. The obtained results provided a new insight into landscape–water quality relationships in lowland agricultural landscape, with a special focus on evaluating the predictive performance of different land cover metrics and datasets.

“…Global warming and eutrophication might reduce the availability of fresh water, especially in dry areas (Kundzewicz et al. ), and might also lead to reductions in the quality of freshwater habitats (Dorgham ). This may have indirect effects on bats as, for example, successful lactation in a bat species living in an arid area is related to water availability (Adams & Hayes ).…”

“…Knowing the extent to which bats depend on aquatic resources may also help us to predict the effects on bats of climate change and eutrophication, which are threats to freshwater systems. Global warming and eutrophication might reduce the availability of fresh water, especially in dry areas (Kundzewicz et al 2008), and might also lead to reductions in the quality of freshwater habitats (Dorgham 2014). This may have indirect effects on bats as, for example, successful lactation in a bat species living in an arid area is related to water availability (Adams & Hayes 2008).…”

Bats and aquatic habitats: a review of habitat use and anthropogenic impacts

Many bats use aquatic habitats for foraging and for drinking water. Interactions between aquatic and terrestrial systems are important for understanding food web dynamics and for conserving species and ecosystems. Therefore, in this review, I examined the data available on bats’ use of aquatic habitats. The objectives of the present review were to evaluate the importance of aquatic resources for bats and to identify the effects that eutrophication, water pollution, and other anthropogenic impacts on water bodies have on bats. Most studies on bats and aquatic habitats have been conducted in Europe or in North America. They show, directly or indirectly, how bats use aquatic resources. Acoustic survey is the most common technique employed to assess habitat use by bats, although some researchers have used radio telemetry or other methods. Myotis daubentonii is the most commonly studied species. Within this topic, research does not tend to be focused more on threatened species. The effects of water pollution and eutrophication on bats remain unclear: different effects are reported for different species and in different areas. More studies are needed from Africa, South America, and Asia, regions for which few data are available, as well as from arid regions where fresh water is a limited resource.

“…The results of this study indicate that access to the examined lakes should be limited (Figures 9 and 10). Tourist infrastructure in the evaluated trail segments should be upgraded, for example by introducing barriers to separate visitors from the lakes (segments number 2, 3,4,5,6,11,14,16,17,18,24,26) and by eliminating lake access points and illegal paths (segments number 1,7,8,9,10,12,13,15,25,28,29,30,31, and an illegal path south of Lake Zadni Staw Polski) (Figure 7). the studied lakes, and wastewater should be directed to the existing wastewater treatment plant at the shelter.…”

“…Unnatural proliferation of all types of algae (both microalgae and macroalgae, i.e., hydromacrophytes), in water is considered to be the main symptom of eutrophication. Algal growth is stimulated not only by external factors such as sunlight availability and the physicochemical properties of water (nutrient content, temperature, transparency and pH), but also by the hydrodynamic regime of a water body, including water disturbance, flow velocity and flow rate [11,[27][28][29]. According to the literature, ecological models are valuable tools for investigating lake eutrophication and managing lake ecosystems [26,30,31].…”

An Evaluation of the Impact of Hiking Tourism on the Ecological Status of Alpine Lakes—A Case Study of the Valley of Dolina Pięciu Stawów Polskich in the Tatra Mountains

et al. 2020

Eutrophication is one of the major threats to the quality of water in high mountain lakes. The inflow of elements having biological origin may significantly aggravate the ecological status of those ecosystems. For this reason, the aim of this study was to map and assess the impact of anthropogenic pressure on alpine lakes in the valley of Dolina Pięciu Stawów Polskich (known in English as the Valley of Five Polish Lakes) in the Tatra National Park in Poland. The effects of tourism and easy access to alpine lakes on changes in their ecological status were determined. Tourist trails were evaluated based on the difficulty of access to the water surface of analyzed alpine lakes, with a method developed for assessing anthropogenic pressure on aquatic ecosystems. The method, deployed for the first time in 2019, was modified and adapted to the local environmental conditions in the research area. The results of this study indicate that tourism pressure contributes to the growth of submerged vegetation in alpine lakes. The presence of aquatic plants (including vascular plants) shows ecosystem response to water enrichment with biogenic substances. The present findings were used to formulate practical recommendations and propose modifications to the evaluated hiking trails. The research method developed in the study can support analysis and control of tourist traffic, thus reducing anthropogenic pressure on alpine lakes in national parks located in mountain areas.
