“…Shallow lakes are expected to be particularly influenced by climate warming (Baulch et al 2005;Carvalho and Kirika 2003;Gyllstrom et al 2005;Moss et al 2003). The fact that the global distribution of lakes is dominated by millions of small water bodies (Downing et al 2006) suggests that the response observed in this experiment to warming may be important to carbon cycling on a global scale.…”

There is an urgent need to understand the effect of climate warming on the carbon dynamics of lakes and ponds in order to assess contributions to global carbon budgets. Currently, we are unable to predict how the exchange of carbon gases (i.e. CO 2 ) across the air-water boundary and organic carbon storage in the sediments will be altered with realistic warming scenarios downscaled from climatic models. Given the prevalence of shallow systems and tight atmospheric coupling, we conducted a mesocosm experiment to test the impacts of warming on CO 2 saturation in a shallow prairie pond. We outline and test three possible scenarios for the effect of warming on the CO 2 saturation of ponds, resulting in either an increase, decrease or no net effect for CO 2 saturation. We show that with approximately a two-degree (8C) increase in average water temperature, the pCO 2 of the warmed mesocosms was nine times greater than the ambient temperature mesocosms by the end of the 5-week experiment. Changes in water colour (a measure of dissolved organic carbon) in warmed systems indicate that decomposition of organic matter in the sediments and water column was the main contributor to the increase in pCO 2 in the warmed mesocosms. Our results show that with warming, the release of CO 2 from shallow ponds to the atmosphere will increase and carbon storage in the sediments will decrease, altering the current functioning of shallow prairie ponds and influencing the contribution of ponds to the global carbon cycle.

“…This is because submerged macrophytes in shallow lakes can form a dense vegetation that controls phytoplankton biomass through several mechanisms, including allelopathic interactions (Gross, 2003), nutrient limitation (Van Donk et al, 1993), shading and providing of a refuge for zooplankton that can control phytoplankton by grazing (Timms & Moss, 1984;Schriver et al, 1995;Burks et al, 2002). Recent studies indicate that zooplankton body size becomes smaller (Gillooly & Dodson, 2000) and that the zooplankton:phytoplankton biomass ratio declines from cold to warm lakes, likely due to enhanced fish predation (Lazzaro, 1997;Gyllström et al, 2005;Jeppesen et al, 2007a;Havens et al, 2009), and that the refuge capacity of submerged macrophyte for zooplankton is lower in warm lakes where fish are very abundant in the vegetation (Meerhoff et al, 2007a, b;Teixeira-de Mello et al, 2009).…”

Influence of nutrients, submerged macrophytes and zooplankton grazing on phytoplankton biomass and diversity along a latitudinal gradient in Europe

In order to evaluate latitudinal differences in the relationship of phytoplankton biomass and diversity with environmental conditions in shallow lakes, we sampled 98 shallow lakes from three European regions: Denmark (DK), Belgium/The Netherlands (BNL) and southern Spain (SP). Phytoplankton biomass increased with total phosphorus (TP) concentrations and decreased with submerged macrophyte cover across the three regions. Generic richness was significantly negatively related to submerged macrophyte cover and related environmental variables. Zooplankton:phytoplankton biomass ratios were positively related to submerged macrophyte cover and negatively to phytoplankton generic richness in DK and BNL, suggesting that the low generic richness in lakes with submerged macrophytes was due to a higher zooplankton grazing pressure in these regions. In SP, phytoplankton generic richness was not influenced by zooplankton grazing pressure but related to conductivity. We observed no relationship between phytoplankton generic richness and TP concentration in any of the three regions. The three regions differed significantly with respect to mean local and regional generic richness, with BNL being more diverse than the other two regions. Our observations suggest that phytoplankton diversity in European shallow lakes is influenced by submerged macrophyte cover indirectly by modulating zooplankton grazing. This influence of submerged macrophytes and zooplankton grazing on phytoplankton diversity decreases from north to south.

“…Temperature is one of the most important physical factors determining biological processes in aquatic environments (de Azevedo and Bonecker, 2003;Gyllström et al, 2008;Starmach et al, 1976;Vadadi-Fülöp et.al., 2009). The average water temperature in the oxbow lake isolated from the Vistula River was lower than in the lake connected with the river.…”

Floodplain lakes are important elements of landscapes with large rivers. In this study we compared planktonic communities of two oxbow lakes of the Vistula River. We investigated how the inflow of the river's water affected their physicochemical and biological conditions including water temperature, water transparency, oxygen concentration, and macrophyte coverage of the bottom. These parameters in turn affected plankton community. The average phytoplankton abundance in the isolated lake was over two times lower than in the lake connected to the river. Cryptophyta dominated in the phytoplankton community in the isolated lake and diatoms -in the lake supplied with water from the river. The average abundance of zooplankton in the isolated lake was more than twice as high as that in the lake which was connected to the river. The first lake proved to be more attractive for zooplankton due to its stable living conditions (similar to the conditions observed in ponds), higher temperature in summer, and nutrient availability due to the high abundance of small phytoplankton. The results of our research indicate that species composition, plankton abundance, and Chl-a concentration depended on whether there was water exchange between the particular lake and the Vistula River. Hydrological conditions shaped the relationships between the components of the biota.
