,A multidisciplinary study of the lake Bj?resj?sj?n (S Sweden): land-use history, soil erosion, lakeive forest clearings and dominant pastoral farming). With the expansion of arable farming (around 650 AD), human impact on the landscape was the major factor influencing soil erosion processes in the catchment and limnological changes in the lake.作者: 繁忙 時間: 2025-3-22 01:45
Sequential inorganic chemical analysis of a core from Slapton Ley, Devon, UK, reflect the intensification of agriculture post-1945, and the construction of Slapton sewage treatment works in 1953. A major peak in authigenic nitrogen, 6 cm below the present sediment surface, is correlated with the severe 1976 drought in the UK. The ecosystem of the Ley appears to have been tri作者: Eructation 時間: 2025-3-22 04:42 作者: exclamation 時間: 2025-3-22 11:21 作者: 可憎 時間: 2025-3-22 13:54

Paleolimnology of Slapton Ley, Devon, UK,e uppermost sediments shows that the Ley has recently experienced a major shift in its trophic status, changing from a clear water, macrophyte lake to one dominated by plankton in a hypertrophic system. This last point is further amplified in the paper by Heathwaite & O’Sullivan (1991).作者: faucet 時間: 2025-4-1 16:32
