The aim was to evaluate how topographical (soil and vegetation pools in the catchment) and morphological (catchment-to-lake area ratio) characteristics of catchment-lake systems affect in-lake nutrient structures in remote mountain areas. Concentrations of dissolved organic carbon (DOC), total phosphorus (TP), and total organic nitrogen (TON) were closely related (p < 0.001) to each other in lakes and their inlets. Terrestrial TP export (57-1183 mu mol m(-2) yr(-1) on a catchment area basis) and lake-water TP concentrations (0.05-1.0 mu mol L(-1)) were closely associated with DOC leaching, exhibiting significant (p < 0.001) exponential relationships with increasing soil cover in the catchments. Precipitation fluxes of TP (460-918 mmol m(-2) yr(-1), average 692 mu mol m(-2) yr(-1), with 50\% being soluble reactive P) increased with precipitation along the elevation gradient and were highest in windy mountain areas. The C: N and C: P ratios of external nutrient inputs to the lakes were higher for terrestrial than atmospheric sources by a factor of similar to 4 and 32, respectively, and the relative atmospheric contribution to the total external P loading of lakes was inversely related to the soil cover of catchments and the ratio between catchment and lake areas. The different composition and proportion of terrestrial and atmospheric nutrient inputs to mountain lakes along the vegetation zones determine the stoichiometric balance between the DOC and P available as nutrients for the food webs of natural mountain lakes.}, issn = {0024-3590}, doi = {10.4319/lo.2011.56.4.1343}, author = {Jiri Kopacek and Josef Hejzlar and Jaroslav Vrba and Evzen Stuchlik} } @article {KopacekKanaEtAl_2004, title = {Chemical and biochemical characteristics of alpine soils in the Tatra Mountains and their correlation with lake water quality}, journal = {Water Air and Soil Pollution}, volume = {153}, number = {1-4}, year = {2004}, month = {mar}, pages = {307-327}, abstract = {Soils and lakes were sampled in fifteen catchments in the alpine zone of the Tatra Mountains (Slovak-Polish border) to evaluate the dependence of lake water chemistry on soil properties. The amount of soil in alpine meadows varied from 38 to 255 kg m(-2) (dry weight soil <2 mm; average of 121 kg m(-2)). The average cation exchange capacity (CEC) was 12 eq m(-2), average base saturation was 12\%, and average pH(CaCl2) was 4.0. Moraine areas had, on average, 13 kg m(-2) of <2 mm soil in small deposits between stones. Their chemical properties were similar to mineral horizons of alpine soils but had higher concentrations of P forms. Soil composition was spatially uniform, having coefficients of variation of all parameters between 5 and 115\%, and did not exhibit significant differences between the catchments or along the elevation gradient. Variation in pools of soil constituents was similar to2-fold higher. Soil organic matter concentration was the parameter that most strongly and positively correlated with N, P, S, CEC, exchangeable base cations, exchangeable acidity, and all biochemical parameters (C, N, and P in microbial biomass and C and N mineralisation rates). Lake water concentrations of organic C, N, and total P were positively correlated (P < 0.01) with the pool of soil organic matter in the catchments, while NO3- concentrations were negatively correlated (P < 0.001). No correlations were found between C, N, and P concentrations in lakes and soil chemistry, indicating the dominant role of soil quantity over quality for surface water composition in the Tatra lakes. Relatively high concentrations of Ca2+, Na+, SO42-, reactive Si, and acid neutralising capacity in some lakes were not explained by soil characteristics, and were more probably related to bedrock composition and structure.}, author = {Jiri Kopacek and Jiri Kana and Hana Santruckova and Tomas Picek and Evzen Stuchlik} } @article {2311, title = {Hysteresis in reversal of Central European mountain lakes from atmospheric acidification}, journal = {Water Air Soil Pollut.
