    Climate change accelerates recovery of the Tatra Mountain lakes from acidification and increases their nutrient and chlorophyll a concentrations

  • Original language description

    We evaluated changes in the concentration of cations, anions, nutrients (dissolved organic carbon, DOC; phosphorus, P; and nitrogen forms including nitrate, NO3- and total organic nitrogen, TON), and chlorophyll a (Chl-a) in 31 Tatra Mountain lakes in Slovakia and Poland during their recovery from acidic deposition (1992-2018). Typical effects of decreasing acidic deposition on the lakes&apos; water composition, such as decreasing base cation concentrations, were confounded by climate change and catchment characteristics, including areal proportions of well-developed soils and scree. A climate-related increase in physical erosion provided freshly exposed unweathered granodiorite (the dominant bedrock) to chemical weathering. Dissolution of accessory calcite in the granodiorite increased the in-lake Ca2+ and HCO3- concentrations and reversed the Ca2+ trends, which originally decreased in parallel with strong acid anions. These changes were most pronounced in steep, scree-rich areas, which are most sensitive to physical weathering. Fresh apatite [Ca-5(PO4)(3)(F, Cl, OH)] in the crushed granodiorite acts as a P source at soil pH&apos;s between 4 and 5 and in the presence of chelating organic acids within soils. These conditions enhance apatite solubility, which in part explains increasing P in lakes with scree-dominated catchments. Soil recovery from acidification due to decreasing acidic deposition and the neutralizing effect of weathering of erosion-derived accessory calcite were the most likely causes of elevated DOC and P export from soils. Their elevated leaching was accompanied by increasing in-lake concentrations of Chl-a and TON. The increasing TON concentrations were, as for Ca2+, most pronounced in the scree-rich catchments, and represented the most sensitive indicator of the changes in the lake water nutrient composition.
