“…Methylmercury is increasing over time in some lakes (e.g., Meyer et al 2011) and pH is remaining stable over time in most lakes in southeastern Canada (Jefferies et al 2003a), which likely explains why reproductive success in this study decreased over time. Methylmercury concentrations are higher (e.g., Bodaly et al 1993) and pH (e.g., Eilers et al 1983) and abundance of forage fish (e.g., Piper et al 2012) are lower in smaller than in larger lakes, which likely explains why reproductive success in this study was lower in smaller than in larger lakes. Also, methylmercury concentrations are higher where pH is lower (e.g., Jeremiason et al 2006), which combined with the direct negative effects of low pH on food supply, likely explains why reproductive success in this study was lower where pH was lower.…”

“…By virtue of their volume, smaller lakes also have lower total numbers of fish than larger lakes (Alvo et al 1988, Piper et al 2012. Moreover, some smaller lakes receive relatively larger inputs from acid precipitation and hold fewer substances that neutralize acids compared to larger lakes (Eilers et al 1983), which means that smaller lakes generally have lower pH than larger lakes (e.g., Rago and Wiener 1986, Matuszek and Beggs 1988, McNicol et al 1995. Thus, smaller lakes typically are warmer and have lower pH than larger lakes, which likely explains why methylmercury is more abundant in smaller lakes (Bodaly et al 1993, Jeremiason et al 2006.…”

ABSTRACT. Reproductive success of Common Loons (Gavia immer) is a powerful indicator of aquatic ecosystem health, especially in relation to mercury and acid precipitation. We examined relationships between Common Loon reproductive success and longitude, year, lake area, and pH across southern Canada using data collected from 1992 to 2010 by participants in Bird Studies Canada's Canadian Lakes Loon Survey. Our goal was to indirectly describe the health of lakes in southern Canada with respect to mercury and acid precipitation. The overall model-predicted number of six-week-old young per pair per year was 0.59 (95% confidence limits: 0.56-0.62). Six-week-old young per pair per year decreased by 0.19 from west-to-east (−127° to −52° longitude), decreased by 0.14 between 1992 and 2010, increased by 0.22 as lake area increased from 10 to 3000 ha, and increased by 0.43 as acidity decreased from pH 5 to 9. The relationships were likely linked to acid-and temperature-mediated exposure to methylmercury and/or acid-induced reductions in forage fish. The temporal decrease

Mass balances of total nitrogen and total phosphorus were calculated for Lake Verevi (area 0.126 km 2 , maximum depth 11 m, mean depth 3.6 m), a sharply stratified small lake located in South Estonia within the borders of the town Elva. The lake has up to 10 small inflows but only three of them are nearly permanent. Accidental overflows from near-by oxidation ponds during high floods have been the major source of the nutrient load of the lake in the past. L. Verevi receives a significant part of its inflow from groundwater, which is difficult to measure. In dry years the outflow is temporary. During summer the lake is sharply thermally and chemically stratified. The spring turnover is often incomplete even in homothermal conditions, thus giving the lake some meromictic features. The influx of nitrogen exceeded the outflux at any supposed proportion (20%, 50%, 80%) of surface runoff. The lake retained 45-90% of the nitrogen influx by sedimentation and/or by denitrification. The largest nitrogen losses with loss rates more than 10 kg N d )1 occurred in May and June. The calculated phosphorus retention rate became strongly negative during mixing periods. From June to November, phosphorus release from the sediment exceeded sedimentation by 205 kg in 1991 and by 79 kg in 1993. Earlier stagnation and absence of a full spring turnover in the 2000 has slowed down the recovery of the lake because less phosphorus is flushed out. However, the stronger stratification and significantly smaller phosphorus content in the epilimnion limits biological activity and as a result improves the water quality of the surface layer.

“…Such climatic forcing appears to affect nutrient availability through mixing and the amount of heat loading to the system. Lakes also have strong hydrological interactions with their catchments that are influenced by atmospheric deposition, evapotranspiration, and land use-all of which are strongly affected by climate (Schindler et al 1990;Eilers et al 1983).…”

The June 199 1 eruption of Mt. Pinatubo had a marked cooling on global climate that was evident in the regional air temperatures of the northeastern U.S. This climatic perturbation coincided with the 199 l-l 994 pilot surveys initiated by the Environmental Monitoring and Assessment Program-Surface Waters (EMAP-SW). Regional air and summer profile water temperatures for 1992 were significantly lower (-l-2°C) than in the same July-August sampling period in 199 1, 1993, or 1994. Richness of major zooplankton groups such as rotifers and small cladocerans also varied markedly with the 1992 cooling. The median of 323 randomly selected survey lakes had 2-10 additional species of zooplankton per lake in 1992 than in the warmer years of 199 1, 1993, or 1994. This response represented an increase of 7-34% in local richness across lakes. Regional richness was also 17-32% higher in the cooler year. ANOVA showed that total zooplankton richness had a highly significant year effect, suggesting a response to annual climatic differences. The difference in total richness in 1992 was attributed primarily to richness of rotifers and small cladocerans. On the other hand, the richness of large cladocerans and copepods did not show significant year effects, suggesting that their responses may occur at time scales that are longer than the temporal scale of this 4-yr survey. These results indicate that local zooplankton richness can be effectively extrapolated to regional scales for the monitoring of lakes to climate change.
