“…Climate-related changes will challenge the protection and use of ecosystem services such as water supply, industry, recreation and fisheries, not least because nutrient loading and climate warming effects act in synergy (Jeppesen et al, 2010;Moss et al, 2011; Jeppesen et al, 2014). Adaptation and management actions are needed, but to be sufficiently efficient they should be based on the knowledge of the key functions of the ecosystem.…”

“…More detailed studies and new practical tools, in particular better buffering of the system to hydrological extremes, are needed to compensate for the climate change-induced higher nutrient loading, as highlighted also in other studies (Trolle et al, 2011;Jeppesen et al, 2014). Controlling the nutrient load during very rainy periods and extreme weather events may turn out to be a strongly demanding and almost impossible task.…”

“…It is expected that the pressure on lakes and their ecological state will increase in the future due to both an increasing world population, demanding a higher food production and to climate change (Millennium Ecosystem Assessment, 2005). Such changes will further challenge the protection and use of ecosystem services of the lakes such as water supply, industry, recreation and fisheries, not least because nutrient loading and climate warming can have a synergistic effect (Jeppesen et al, 2010;Moss et al, 2011;Jeppesen et al, 2014). Thus, adaptation and management actions are often needed.…”

Ecosystem change in the large and shallow Lake Säkylän Pyhäjärvi, Finland, during the past ~400 years: implications for management

Lake Säkylän Pyhäjärvi has been an important fishing site and drinking water source for the local population for centuries. The lake has undergone significant changes: (1) the water level was lowered in the 1600s and in the 1850s; (2) planktivorous coregonid fish were successfully introduced in the early 1900s; (3) nutrient input from intensified agriculture has increased since the 1950s and (4) the effects of the current variable climate on the lake and its catchment have become more evident since the 1990s. We determined the phases of oligotrophication, eutrophication and recovery and elucidated the ecosystem changes by combining palaeolimnological records with detailed neolimnological data. The sedimentary diatom and cladoceran assemblages first showed a relatively eutrophic period followed by oligotrophic periods, linked with the artificial changes in water level and consequent shifts in macrophyte abundance. The oligotrophic period in the early 1900s is thought to represent the target trophic state for the lake. After the 1950s, introduction of vendace resulted in higher planktivory reflected by an increased relative abundance of small-bodied pelagic cladocerans. Signs of eutrophication occurred due to increased nutrient load. During the last 10 years, signs of recovery have been recorded. A complex history such as that of Lake Pyhäjärvi illustrates the difficulties in selecting management targets, and the risk of setting false targets, for lakes based solely on monitoring data-both neolimnological and palaeolimnological approach are needed.

“…Incorporating Lake Rotcze into the drainage network substantially lowered natural fluctuations in water level. This mechanism will also counteract water level increases in the future as climate models predicted enhanced net precipitation in the North temperate zone (IPCC, 2014), particularly during winter (Jeppesen et al, 2014).…”

“…Long-term observation of both natural-and human-influenced conditions are required to determine the drivers of plant succession which often act concurrently (e.g. Jeppesen et al, 2014) and so place complex pressures on the lake ecosystem. Palaeolimnology is a wellestablished method to approach these questions (Battarbee, 1999;Davidson et al, 2013) because the limitations of the methods are now well understood (e.g.…”

Disentangling natural and anthropogenic drivers of changes in a shallow lake using palaeolimnology and historical archives

et al. 2015

Shallow lakes are susceptible to catastrophic regime shifts characterised by the presence or absence or macrophytes. However, the long-term controls on macrophyte succession in shallow lakes are incompletely understood. To investigate this, we analysed multiple sediment proxies in Lake Rotcze (Eastern Poland), a small, shallow and densely macrophyte-covered lake to (1) reconstruct the 'reference conditions' (sensu WFD) and development of the lake in recent centuries, (2) compare historical evidence with the sedimentary record, and (3) identify the natural and anthropogenic drivers of macrophyte succession. Before the twentieth century, conditions in the lake may be referred to as 'reference conditions'. Subsequently forest clearance in the catchment resulted in lower water transparency, but concurrent catchment drainage lowered water levels and increased macrophyte development. Since 1950 elevated nutrient supply and climatically driven increases in water levels led to the deterioration of water transparency and partial macrophyte withdrawal. At the end of the twentieth century lake-level drawdown led to low phytoplankton biomass and clear water creating a novel ecosystem where macrophytes invade the whole lake. These patterns suggest that both natural and anthropogenically induced water level fluctuations have been critical drivers of macrophyte development.

Excess warming of a Central European lake driven by solar brightening

2016

Recent trends in summer surface temperatures of many lakes exceed the corresponding air temperature trends. This disagrees with expectations from lake surface heat budgets, which predict that lake surface temperatures should increase by 75–90% of the increase in air temperatures. Here we investigate the causes for this excess warming for Lower Lake Zurich, a representative deep and stratified Central European lake, by a combined data analysis and modeling approach. Lake temperatures are simulated using a one‐dimensional vertical model driven by 33 years of homogenized meteorological data. The model is calibrated and validated using an equally long time series of monthly water temperature profiles. The effects of individual forcing parameters are investigated by scenarios where the trends of single variables are retained while those of all other forcing variables are removed. The results show that ∼60% of the observed warming of spring and summer lake surface temperatures were caused by increased air temperature and ∼40% by increased solar radiation. The effects of the trends of all other forcing variables were small. Following projections of climate models, the increasing trends in solar radiation, and consequently the excess warming of lake surface temperatures, are not likely to continue in the future.
