“…Because phosphate is often the limiting nutrient in lakes (e.g. Maberly et al 2003;Petaloti et al 2004), this could stimulate primary production (Holmer and Storkholm 2001 and references therein). In recent years, in North America and especially in Europe, lake sulfate has declined (Tipping et al 1998;Stoddard et al 1999) as a consequence of the enforcement of legislations limiting SO 2 emissions (Cape et al 2003).…”

Sulfur is one of the critical elements in living matter, as it participates in several structural, metabolic and catalytic activities. Photosynthesis is an important process that entails the use of sulfur during both the light and carbon reactions. Nearly half of global photosynthetic carbon fixation is carried out by phytoplankton in the aquatic environment. Aquatic environments are very different from one another with respect to sulfur content: while in the oceans sulfate concentration is constantly high, freshwaters are characterized by daily and seasonal variations and by a wide range of sulfur concentration. The strategies that algal cells adopt for energy and resource allocation often reflect these differences. In the oceans, the amount and chemical form of sulfur has changed substantially during the course of the Earth's history; it is possible that sulfur availability played a role in the evolution of marine phytoplankton communities and it may continue to have appreciable effects on global biogeochemistry and ecology. Phytoplankton is also the main biogenic source of sulfur; sulfur can be released into the atmosphere by algal cells as dimethylsulfide, with possibly important repercussions on global climate. These and related matters are discussed in this review.

Ecological impacts of global warming and water abstraction on lakes and reservoirs due to changes in water level and related changes in salinity

et al. 2015

According to the Intergovernmental Panel on Climate Change report released in September 2014, unprecedented changes in temperature and precipitation patterns have been recorded globally in recent decades and further change is predicted to occur in the near future, mainly as the result of human activity. In particular, projections show that the Mediterranean climate zone will be markedly affected with significant implications for lake water levels and salinity. This may be exacerbated by increased demands for irrigation water. Based on long-term data from seven lakes and reservoirs covering a geographical gradient of 52°of latitudes and a literature review, we discuss how changes in water level and salinity related to climate change and water abstraction affect the ecosystem structure, function, biodiversity and ecological state of lakes and reservoirs. We discuss mitigation measures to counteract the negative effects on ecological status that are likely to result from changes in climate and water abstraction practices. Finally, we highlight research required to improve knowledge of the impacts of anthropogenically induced changes on lake water level and consequent changes in salinity.

“…The scarceness of O 2 on the bottom is indicative of lack of organic contamination and eutrophication of the lake (Premazzi and Chiaudani, 1992). This was also confirmed by the values of BOD 5 , a parameter generally evaluated to define the trophic status of lakes (Petaloti et al, 2004). The values were extremely low at the surface, and were not measurable in the medium and bottom layers.…”
