The United Kingdom Acid Waters Monitoring Network Data Report for 2005-2006 (year 18)

The UK Acid Waters Monitoring Network (UKAWMN) has been operating continuously since 1988. During the first ten years biological and chemical data were summarised in an annual series of printed reports From the year 2000 annual data reports have also been available from the UKAWMN web page. These are of a similar format to earlier annual reports but focus on graphical representations of time trends in raw data and diagnostic statistics (e.g. species richness and diversity indices). Detailed analysis of data is presented in two interpretative reports, Monteith (2005) and Monteith and Evans (2000) dealing with 15 and 10 years of accumulated results respectively. Both are also available on the UKAWMN web page. A full description of sampling methods and analytical procedures, together with site descriptions, are also presented on the UKAWMN web page

Atlantic salmon Salmo salar in the chalk streams of England are genetically unique.

This is the author accepted manuscript. The final version is available from Wiley via the DOI in this recordRecent research has identified genetic groups of Atlantic salmon Salmo salar that show association with geological and environmental boundaries. This study focuses on one particular subgroup of the species inhabiting the chalk streams of southern England, U.K. These fish are genetically distinct from other British and European S. salar populations and have previously demonstrated markedly low admixture with populations in neighbouring regions. The genetic population structure of S. salar occupying five chalk streams was explored using 16 microsatellite loci. The analysis provides evidence of the genetic distinctiveness of chalk-stream S. salar in southern England, in comparison with populations from non-chalk regions elsewhere in western Europe. Little genetic differentiation exists between the chalk-stream populations and a pattern of isolation by distance was evident. Furthermore, evidence of temporal stability of S. salar populations across the five chalk streams was found. This work provides new insights into the temporal stability and lack of genetic population sub-structuring within a unique component of the species' range of S. salar.This research was funded by the Game & Wildlife Conservation Trust and the Atlantic Salmon Trust, with additional support from the Salmon and Trout Association, the Westcountry Rivers Trust and the University of Exeter

The United Kingdom Acid Waters Monitoring Network Data Report for 2003-2004 (year 16)

The UK Acid Waters Monitoring Network (UKAWMN) has been in continuous operation since 1988. For the first ten years biological and chemical data were summarised in an annual series of printed reports and these were followed by a detailed analysis of data in an interpretative report (Monteith and Evans, 2000), which is available on the UKAWMN web page. From the year 2000 annual data reports have been available from the UKAWMN web page. These are of a similar format to earlier annual reports but focus on graphical representations of time trends in raw data and diagnostic statistics (e.g. species richness and diversity indices). An analytical report, providing an interpretation of the first 15 years of data will be completed and made available on the project web page in the near future. A full description of sampling methods and analytical procedures, together with site descriptions, is presented in Patrick et al. (1991)

The United Kingdom Acid Waters Monitoring Network Data Report for 2000-2001 (year 13)

The UK Acid Waters Monitoring Network (UKAWMN) has been in continuous operation since 1988. For the first ten years biological and chemical data were summarised in an annual series of printed reports and these were followed by a detailed analysis of data in an interpretative report (Monteith and Evans, 2000), which is available on the UKAWMN web page. From this year annual data reports will be solely available from the UKAWMN web page. These will be of a similar format to earlier annual reports but will primarily concentrate on graphical representations of time trends in raw data and diagnostic statistics (e.g. species richness and diversity indices). A full description of sampling methods and analytical procedures, together with site descriptions, is presented in Patrick et al. (1991)
