“…Consequently, the contact of the water to natural bedrock that is mainly composed of gneiss (Moores and Fairbridge, 2006) was reduced or prevented. In a study on young gravel pits in Canada, which, although located at lower elevations, are comparable to the mountain reservoirs in structure and age, however, significantly lower concentrations of phosphorus and nitrogen were found (Vucic et al, 2019). Another factor influencing the abiotic conditions in the mountain reservoirs was the origin of the water, though this aspect was not directly addressed here.…”

Climate warming has multiple effects on an environment. Especially the Alpine region is affected by changing conditions, which do not only have ecological but also economic impacts in respect to winter sports tourism. Due to higher environmental temperatures and less precipitation, artificial snow making is becoming increasingly important and consequently, mountain reservoirs for water storage are built. In these systems, planktonic communities are not only influenced by the naturally harsh environmental conditions of the alpine region, but also by severe changes in water level fluctuations due to water withdrawal and re-filling within short time periods. Information on planktonic communities and species traits in such man-made water bodies is nonexistent. Here, we focused on ciliates, a group of unicellular protists known to adapt and respond rapidly to changing environmental conditions. Simultaneously, we identified abiotic and other biotic factors that shaped these microbial communities. We investigated the species composition, abundance and species traits of ciliates in eleven mountain reservoirs in the Tyrolean Alps, Austria, and hypothesized that these communities differed significantly from natural ones. The mountain reservoirs were investigated twice during the ice-free season and water chemistry, chlorophyll a, bacteria, zooplankton, and ciliates were sampled. We detected 48 ciliate taxa in total, with an average of five taxa per mountain reservoir. A wide range of abundance (summer: 24 to >15,600 Ind L−1; autumn: 38 to ∼7,500 Ind L−1) and no clear pattern in the community composition was found, most likely due to water level fluctuations and the source of water used for filling the mountain reservoirs. The ciliate abundance was significantly affected by pH, nutrients, but also water transparency and potential predators (crustaceans). Planktonic ciliates dominated the mountain reservoirs and, surprisingly, mixotrophic species, typically found in natural (alpine) lakes, were only rarely observed. Our data suggest that in these fast-changing systems, local factors seem to be more important than regional ones.

“…Our results indicated that GPPs have an important ecological role for floodplain wetland fishes and can compensate for wetland loss. Although our study focused only on floodplain wetland fishes, various types of organisms inhabit GPPs (including gravel pit lakes) (Emmrich et al, 2014; Santoul et al, 2009; Seelen et al, 2021; Søndergaard et al, 2018; Vucic et al, 2019; Zhao et al, 2016). Since ecological values often differ among taxa (e.g., Yamanaka et al, 2020), it is important to clarify the ecological value of GPPs for other floodplain wetland taxa in future studies.…”

“…Given the increased demand for geomaterials, the construction of GPPs may continuously increase in the future. Diverse organisms, such as fish, birds, plants, zooplankton, and macroinvertebrates, inhabit GPPs (including gravel pit lakes) (Emmrich et al, 2014; Santoul et al, 2009; Seelen et al, 2021; Søndergaard et al, 2018; Vucic et al, 2019; Zhao et al, 2016). Previous studies on human‐altered floodplain landscapes have examined the difference in macrophyte community structures between GPPs and other pooled water bodies, including artificial canals and natural lakes.…”

Ecological value of gravel pit ponds for floodplain wetland fish

Floodplain wetlands support high biodiversity, but they have been degraded and geographically fragmented due to human activities. Some types of human‐created waterbodies have received growing attention as alternative habitats for conserving wetland biodiversity. Gravel pit ponds (GPPs) are human‐created wetlands formed when a gravel pit is excavated at or below the water table and filled with groundwater. Differences in community structure among GPPs and floodplain wetlands with respect to habitat characteristics are scarcely known, resulting in insufficient evaluations of the ecological value of GPPs for floodplain wetland species. In this study, we evaluated the ecological value of GPPs for wetland fishes in floodplain landscapes. We surveyed fish abundance, community composition, and 10 environmental factors in GPPs and two types of floodplain ponds (remnant ponds and river backwaters) to clarify the biotic and abiotic differences among the pond types. Environmental factors were similar among the pond types, with only water temperature and the distance from the main channel to the pond significantly lower in river backwaters. The richness and abundance of native fish species did not differ among the pond types, but species composition did. Rhynchocypris percnura sachalinensis, Carassius sp., and Lethenteron sp. N (one of the two cryptic species of Lethenteron reissneri) were selected as indicator species in GPPs, remnant ponds, and river backwaters, respectively. These results indicate that GPPs provide valuable habitats for wetland fishes in floodplain landscapes and support regional γ diversity. Since many species inhabited the GPPs in this study, including red list species, appropriate management of GPPs is important to conserve wetland fishes.

“…This culminated in relatively large nitrate levels, as the Harabhanga, Searsole and Dalurbandh Pit Lakes specifically receive domestic sewage through drainage systems from the nearby household. (Vucic et al 2019). However, it is possible that this is the pioneer work about the rotifer composition of the coal mine generated pit lake ecosystem in RCF.…”

“…Remarkably few biotic investigations were executed in these water bodies (Ferrari et al 2015) since these researches are complicated to perform and needs specialized methodologies (Woelfl and Whitton 2000). Researchers have, therefore, started to find out different ecological components in these ecosystems, biotic succession and population dynamics (Geller et al 2013;Wołowski et al 2013;Sienkiewicz and Gasiorowski 2015;Vucic et al 2019). The available information is inadequate to identify the trophic position of planktonic species in the mine lakes food system, which is different from that of more traditional lakes.…”

The research looks at the rotifer diversity in five different coal mine generated pit lakes from Raniganj Coal Field Area (RCF), West Bengal, India. The collection methodology was involved monthly sampling (n = 120) to analyze the rotifer diversity using surface hauling with standard plankton net of mesh size 55 µm and water column at different depths (20 cm to 50 cm) for the periods of two years (February 2018 -January 2020). Analyzes of some limnological parameters and macrophytes were also performed following standard protocol. Statistical analysis based on the physicochemical parameters showed that Harabhanga and Dhandardihi 1 Pit Lakes were more similar while Dhandardihi 1 Pit Lake and Dhandardihi 2 Pit Lake were more alike in terms of rotifer community structure. Seventeen taxa of rotifers under the five families were found with varying densities and diversity indices. The highest diversity was observed in the Searsole Pit Lake, and the dominant species was Keratella tropica Apstein. The five pit lakes can be separated from each other based on the variations in rotifer diversity and water quality parameters, advocating the implementation of limnological management. Our results indicated different abiotic and biotic variables influencing the rotifer assemblages and diversity of the pit lakes studied.
