Over a period of 10 years, decision-making processes have been developed to encourage long-term and ambitious thinking in tackling the damaging modifications that have affected these rivers. The programme is based on natural ecosystem function generated by natural riverine processes. The decision-making process aims to tackle practical constraints to more natural river function and to generate strategic plans around which available resources can be harnessed in a coordinated and logical fashion, in partnership with local stakeholders and landowners. The programme has been successful in developing strategic plans for most specially protected rivers in England, and practical implementation of measures is well underway and increasing each year. The process has been valuable in providing a basis for bids to a range of domestic and European funds, and for drawing local stakeholders together within a common delivery framework. Over time, more local stakeholder resources are becoming available as the benefits of restored natural ecosystem function are becoming more apparent. The physical modifications affecting these rivers reflect the impacts on the wider river network in England and in other developed countries. The lessons learnt from this programme over the past 10 years will be of use to those working on river restoration elsewhere in England, the UK, Europe and further afield. Whilst the current global economic outlook for funding is bleak, the processes established in England allow available resources to be harnessed and used in the most efficient way possible. This will be important for river restoration initiatives wherever they are attempted and for whatever purpose.","PeriodicalId":89137,"journal":{"name":"Freshwater reviews : a journal of the Freshwater Biological Association","volume":"8 1","pages":"1 - 25"},"PeriodicalIF":0.0,"publicationDate":"2016-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1608/FRJ-8.1.927","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67393054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, I present some results from a series of airborne campaigns organised in the English Lake District between 1986 and 1991. The main instrument used for the surveys was a Daedalus 1268 Airborne Thematic Mapper. This instrument acquires data in 11 spectral bands ranging from the blue visible to the thermal infrared. The visible band data was used to study the spatial distribution of the phytoplankton and the power-boat movements on the surface temperature of Windermere. The review describes some of the methods used to process the acquired imagery and includes an introduction to the procedures used to analyse the spectral data now being gathered by a new generation of airborne instruments. Introduction The impression that lakes are homogeneous features in a structured landscape is very misleading. Most lakes of spatial scales from a few metres to several kilometres (George, 1993; George & Jones, 1987).

The response mechanisms of zooplankton are diverse and efficient and may explain the success and richness of freshwater zooplankton in optically variable waters. While no single behavioural or physiological protection mechanism seems to be superior, and while several unexplained and contradictory patterns exist in zooplankton UVR ecology, recent increases in our understanding are consistent with UVR playing an important role for zooplankton. This review examines the variability in freshwater zooplankton responses to UVR, with a focus on crustacean zooplankton (Cladocera and Copepoda). We present an overview of UVR-induced damages, and the protection and recovery mechanisms freshwater zooplankton use when exposed to UVR. We review the current knowledge of UVR impact on freshwater zooplankton at species and community levels, and discuss briefly how global change over the last three decades has influenced the UVR milieu in lakes.</p>","PeriodicalId":89137,"journal":{"name":"Freshwater reviews : a journal of the Freshwater Biological Association","volume":"3 2","pages":"105-131"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3079903/pdf/ukmss-34034.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29836313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
