“…insignilobus and Paratanytarsus austriacus appeared to vanish completely from the layers from ca. the mid-1980s, while the relative abundances of Tanytarsus gregarius followed by Heterotrissoclaius marcidus increased (Kubovčík & Bitušík 2006). The major shift in chironomid fauna composition coincides with the extinction of the original species of planktonic Crustacea ) and the MAGICreconstructed shift in water chemistry .…”

“…The species is considered a reliable indicator of acid conditions in the Tatra lakes (Kownacki et al 1999;Bitušík et al 2006). Despite its occurrence at high abundance, head capsules remains are not preserved in the sediment, so it cannot be used in palaeolimnological studies (Kubovčík & Bitušík 2006). Historical data from benthic samples are the only evidence of its presence and changes in abundance over time.…”

“…Palaeolimnological analyses of the sediment records from some Tatra Mountain lakes situated on an acidification gradient have revealed the structure of their chironomid fauna prior to the acidification period (Kubovčík & Bitušík 2006;Bitušík et al 2009). However, if the historical data span a sufficiently long interval, they can also be used for the detection of such changes.…”

Data on benthic macroinvertebrate assemblages of two alpine lakes in the Tatra Mts (Slovakia) collected in 1914, 1933, 1979-1982, 1993-1997, and 2000 were collated and analysed in an attempt to define their relationship to major environmental events affecting these alpine lakes over the last century. The oldest data were considered an important background before the onset of acidification in one of the lakes in the 1950s, while the most current contain possible information on biological recovery. Results show that data from the 1910s are insufficient to characterize the macroinvertebrate fauna. Deep zone assemblages of both studied lakes have remained stable since the 1930s. Changes in the density of dominant species over time were found in the acidified lake, suggesting a connection between an increase in phosphorus and chlorophyll-a concentration. The composition of the littoral assemblages in the acidified lake in the 1930s indicates that the lake was not strongly acidified at that time. A stable composition since the 1980s reflects the ongoing acid stress. Incomplete species data on the non-acidified lake did not allow us to detect possible changes in the littoral fauna related to acidification. Single findings of species indicating a recovery process need longer-term data to confirm such a trend. Results from this study suggest that historical datasets consist of valuable information that can supplement palaeolimnological analyses in the reconstruction of lake ontogeny.

“…The surface of sediment was covered with bryophytes in NE-1 and RO-1, and chironomids were present in surface layers of ∼30% of the sediments sampled. Details on biological analysis of sediments in the Tatra lakes are given elsewhere (Kubovčík & Bitušík, 2006;Sacherová et al, 2006;Štefková, 2006).…”

Concentrations of major nutrients (C, N, P) and acid soluble metals (Ca, Mg, K, Al, Fe, Mn, Pb, and Zn) were determined in modern (0-1 cm) and pre-acidification (5-10 cm) sediment layers collected from 37 alpine and 3 forest lakes in the Tatra Mountains (Slovakia, Poland) in 1996-1998. Sediment composition reflected catchment characteristics and productivity of lakes. In the sediments of alpine lakes, C and N concentrations decreased and Mg increased with a decreasing proportion of vegetation and soil in the catchment. Decreasing Ca:Mg ratios in sediments along the vegetation gradient was inverse to that in water, and could be associated with different ratios of cations in water leachate from catchments and in solids which enter the lake due to soil erosion. Phosphorus concentrations increased with the proportion of moraine areas, with till soils rich in P. Concentrations of C, N, P, and Ca in sediments positively correlated to their concentrations in water. Sediment concentrations of Al and Al:Ca ratios increased with decreasing sediment and water pH. A negative correlation between water pH and concentrations of organic C in water and sediments indicated the important impact of organic acids on the acid status of the lakes exposed to higher terrestrial export of organic matter. Compared to the pre-acidification period, the modern sediments had significantly higher Fe, Mn, Zn, Pb, and K, but lower Mg concentrations. The Zn and Pb enrichment was more evident in oligotrophic alpine lakes than in more productive forest lakes and was independent of lake water or sediment pH. Fe and Mn concentrations in the modern sediments were higher than in ambient soils and bedrock, while those in pre-acidification sediments were similar to contemporary soils and to the rock layer. The enrichment of the modern sediments with Fe and Mn thus probably resulted from both their redox recycling and ecosystem acidification.

“…In Central Europe, scientists have devoted much attention to the acidification of mountain lakes in the Czech Republic, Slovakia, Poland, and Germany, particularly in the Bohemian Forest and the Tatra Mountains (e.g., Vranovský et al 1994;Kownacki et al 2000;Kubovčík & Bitušík 2006;Hořická et al 2006;Krno et al 2006;Stuchlík et al 2006;Fjellheim et al 2009). Over the past half-century, these mountain areas witnessed the most pronounced changes in acidic deposition and lake water composition among all European lake districts (Evans et al 2001), due to steep increases in emission and deposition fluxes of sulfur and nitrogen compounds in the 1950s-1980s and their abrupt reduction after 1989 .…”

Mountain lakes in the Bohemian Forest, on both the Czech and German sides, were atmospherically acidified mainly in the 1960s-1980s and have since been recovering from acidification. In 2007, we performed the first complete study on littoral macroinvertebrates in all eight lakes. The goals of the study were to 1) compare macroinvertebrates in the lakes during the process of recovery and 2) investigate relations between the occurrence of taxa and water chemistry. Lake water pH varied from 4.6 to 5.7, concentrations of dissolved reactive Al and labile Al ranged from 118-601 and 11-470 µg L −1 , respectively, and DOC concentrations were < 6 mg L −1 . Altogether 73 taxa were identified from all lakes; a positive relationship was found between pH and the number of macroinvertebrate taxa. The highest number of taxa was found in the least acidic lakes Laka and Grosser Arbersee, including the mollusk Pisidium casertanum. In contrast, the lowest diversity was found in the most acidified Čertovo jezero. Cluster analyses of macroinvertebrates and water chemistry suggested pH as the key factor influencing the occurrence of macroinvertebrate taxa. An interesting finding was the occurrence of the boreo-montane water beetle Nebrioporus assimilis in Prášilské jezero, which is the first documented record of this species in the Czech Republic since 1960.
