Abstract
Catchment hydro-geomorphological responses to environmental change in the Southern Uplands of Scotland

Lake sediment and geomorphic evidence from the Loch of the Lowes/ St Mary's Loch basin in the central Southern Uplands of Scotland provide a multiproxy reconstruction of changing sediment availability and transmission through the catchment. Argues that close correspondence between the sediment 'flood' archive (dating from 2000BC to the 1990s) and historical records of flooding in Scotland suggests that lake-catchment systems of this type have the potential to yield valuable information on past hydrological response.

The disappearance of the previously abundant moss species Sphagnum imbricatum has been investigated at Butterburn Flow, northern England, using organic geochemical, elemental, macrofossil, pollen and testate amoebae analyses. Variations in the assemblage of peat-forming plants were traded using the macro-fossil distributions as well as the relative chain lengths of n-alkanes and concentrations of 5-n-alkyl resourcinols and triterpols. No significant changes to the vegetation assemblage could be detected prior to the loss of S. imbricatum. Variations in water depth were reconstructed using a testate amoebae transfer function and inferred qualitatively using bulk elemental composition and biomarkers for changing redox conditions in the bog subsurface: the degree of isomerization in the C3 hopares, and the concentration of bishomopherol and archol. Pollen analysis reconstructed the landscape surrounding the mire and revealed evidence for human disturbance. The results suggest that bog surface wetness increased with the transition from Sphagnum imbricatum to Sphagum magelliarium, but the increase was not large and emph{S. imbricatum} coincides with increasing human disturbance surrounding the bog, which may have altered nutrient inputs to the bog surface from agriculturally derived dust, to the detriment of S. imbricatum but to the benefit of S. magelliarium and Eriohome vagination. It is proposed that the stresses imposed by the combination of changing nutrient inputs and a rapidly rising water-table drove the disappearance of S. imbricatum for Butterburn Flow at c. cal. AD 1300.
