描述Shallow lakes are important for their amenity value and the ecosystem services that they support. However, many are located in areas of high population density and intensive farming activity. As such, they are subject to many stressors, including eutrophication and climate change. This book examines 40 years of data from Loch Leven, a shallow lake in the lowlands of Scotland, UK, to gain a better understanding of the links between pollution, climate change and ecological response at the landscape scale. A wide range of topics is presented, including long term changes in nutrient inputs, internal phosphorus loading, water quality, algal concentrations, and the biodiversity of macrophytes, zooplankton, benthic invertebrates, fish and waterfowl. The book provides evidence that attempts to improve ecosystem services at this site in the past have often resulted in unintended consequences for the lake and the local community.  It concludes that successful management actions in the future are likely to be those that incorporate lessons learned from previous decisions. This book will be of great interest to freshwater ecologists working in the field and managers responsible for the protect

,Historical changes (1905–2005) in external phosphorus loads to Loch Leven, Scotland, UK,suggest that inputs in the early 1900s were about 6 t TP year. (0.45 g TP m. year.). By 1985, this had risen to about 20 t TP year. (1.5 g TP m. year.) due to increases in runoff from agricultural land and discharges from point sources. By the late 1970s, increased TP inputs were causing serious deg

Long-term variation and regulation of internal phosphorus loading in Loch Leven,Leven, Scotland. A whole-lake sediment P inventory (upper 3 cm of sediment; 2005) suggested a release-potential of 29.7 tonnes (t) from the release sensitive sediment P pools. 18.5 t was contained within shallow water sediments (<4.5 m water depth) with 7.6 t in deeper water sediments below the phot

Water quality of Loch Leven: responses to enrichment, restoration and climate change, Leven shows, however, that seasonal changes in temperature and rainfall may have positive and negative impacts on water quality. In response to reductions in external nutrient loading, there have been significant reductions in in-lake phosphorus concentrations. Annual measures of chlorophyll . have

Changes in aquatic macrophyte communities in Loch Leven: evidence of recovery from eutrophication?,s are associated with eutrophication and with subsequent recovery from eutrophication when anthropogenic nutrient inputs to the loch were reduced. This study uses macrophyte survey data from 1905, 1966, 1972, 1975, 1986, 1993, 1999 and 2008. In each of the four most modern surveys, the loch was divi

Long-term trends in Loch Leven invertebrate communities,rried out from 1966 to 1973 as part of the International Biological Programme (IBP). The results revealed a reduction in species diversity that was attributed to increasing eutrophication. This work provides a baseline against which the response of the invertebrate communities to subsequent changes

Long-term variations in waterfowl populations in Loch Leven: identifying discontinuities between los importance as a site for overwintering waterfowl. However, no comprehensive assessment of trends in waterfowl at the local versus national scale has been conducted at the site.

Modelling the response of phytoplankton in a shallow lake (Loch Leven, UK) to changes in lake retender to assess the lake’s sensitivity to these two climatic drivers. Whilst the simulated annual mean total chlorophyll . proved relatively insensitive to these changes, at the species level marked changes were recorded. Some species responded positively to increased temperature (e.g. .), some negati

Managing ecosystem services at Loch Leven, Scotland, UK: actions, impacts and unintended consequenchese systems by enhancing one ecosystem service at the expense of another. Loch Leven, Scotland, UK, is a good example of this. Over the past 150 years, the lake has been subjected to hydrological modification, fish stocking and pollution control to improve the delivery of key goods and services. Th
