“…Unfortunately, resistance to metals that historically may not have been present in aquatic systems dictates that either the evolution of new mechanisms or adaptation of those old mechanisms is primarily used for the transport of essential elements. This process is slow as evidenced by the loss of species diversity in highly acidified waterways (12).…”

“…According to Kremleva and Moiseenko [15] and Lacoul et al [16], one of the pressing global problems is the acidification of natural water bodies. An increase in the acidity of natural waters impacts various components of aquatic ecosystems, such as the modification of the geochemical cycles of elements and enhancement of the concentrations of heavy metals by transforming them into the most toxic species [17][18][19], thus causing various adverse biological effects. Surface water ecosystems can neutralize the acid supply due to their buffer capacity.…”

The research was conducted in Karczemne Lake (area, 40.4 ha; maximum (max.) depth, 3.2 m) and Klasztorne Małe Lake (area, 13.7 ha; max. depth, 20.0 m) located in the Kashubian Lake District (Northern Poland). From the beginning of the 1950s, these reservoirs have received municipal and storm wastewater. The long-term process of lake contamination has shaped the specific buffer capacity conditions and influenced the circulation of carbonate and bicarbonate in the water of these ecosystems. Extremely high concentrations of nutrients (Karczemne Lake: max. total phosphorous (TP) level, 7.5 mg P L−1; max. total nitrogen (TN) level, 5.6 mg N L−1; Klasztorne Małe Lake: max. TP level, 20.6 mg P L−1; max. TN level, 43.3 mg N L−1) have caused very intensive primary production processes (Karczemne Lake: max. chlorophyll-a level, 193.40 µg m−3; max. Secchi disc visibility, 0.85 m; Klasztorne Małe Lake: max. chlorophyll-a level, 160.01 µg m−3; max. Secchi disc visibility, 1.15 m). In the polymictic Karczemne Lake, the pH value of all water columns exceeded 10.0 (max. pH, 10.41), and in the meromictic Klasztorne Małe Lake, the pH of the surface water layers oscillated around 9.5. In the polymictic Karczemne Lake, despite intensive photosynthesis, the calcium content and alkalinity were similar throughout the whole water column due to constant circulation. In the meromictic Klasztorne Małe Lake, during the growing season, a decrease in calcium concentration and alkalinity of the surface water layers and an increase in calcium concentration at the bottom were noted.

Temporal trends and spatial patterns of chironomid communities in alpine lakes recovering from acidification under accelerating climate change

et al. 2021

The biological recovery of remote aquatic ecosystems from atmospheric acidification under ongoing climate change is a complex and poorly understood process, often developing along unanticipated trajectories. Our objective was to evaluate the interacting effects of changing water chemistry and climate on the biological recovery of chironomid communities in the Tatra Mountain lake district (Slovakia and Poland), one of the most strongly acidified alpine regions worldwide. Chironomid communities were chosen as a sensitive indicator to disentangle the effects of acidification and climate change. We used sediment records of a shallow, strongly acidified lake, Starolesnianske pleso, plus data on 77 alpine lakes sampled across the whole study region in 2000–2004 and 2010–2014. Paleolimnological data from Starolesnianske pleso revealed a dramatic effect of acidification on the chironomid communities from the mid‐20th century. A rapid decline of water pH and a depletion of the carbonate buffering system were accompanied by the establishment of a species‐poor chironomid community. The previously dominant Tanytarsus lugens‐type was replaced by the congeneric Tanytarsus mendax‐type in the late 1970s. A subsequent reversal of water chemistry from acidification starting in the early 1990s was followed by a compositional change towards a more diverse community. The effect of chemical recovery was, however, overwhelmed by rising temperatures. Tiny larvae of more thermophilous Corynoneura scutellata‐type quickly gained dominance in the lake community. Throughout the lake district, C. scutellata‐type significantly shifted towards higher elevations, by more than 100 m per decade. The absence of significant interactions between recovering water chemistry and rising temperatures suggests independent effects of these processes on chironomid communities. The observed climate‐related compositional shifts towards the dominance of small‐bodied species are in line with the metabolic theory of ecology predicting higher metabolic demands in warmer environments, which can favour smaller, faster growing organisms and may lead to future changes in the ecosystem functioning of alpine lakes in general. The combination of monitoring and palaeoecological data provided a useful tool for tracking environmental changes. This approach may also help in disentangling the roles of other multiple pressures on aquatic ecosystems. The sensitive responses of shallow Starolesnianske pleso to atmospheric acidification and climate warming suggest that small lentic waterbodies could be useful sentinels of freshwater deterioration, thus deserving special attention in the future monitoring of alpine environments.
