sediments of Paleocene (?) age.
Integration and characterization of T-DNA insertion in upland cotton
cotton (Gossypium hirsutum L.) deletion of border genetic transformation transgene copy vector integration
2014/2/24
Copy numbers were evaluated by real-time quantitative PCR, and 149 junctions of T-DNA were isolated by thermal asymmetric interlaced PCR from 92 independent transgenic cotton lines transformed by Agro...
Radon activity concentrations measurements in some Jurassic caves of Poland are presented. The aim is to estimate
the radiation doses to casual visitors, cavers and guides in show caves. Radon levels...
The Plynlimon water balance 1969-1995：the impact of forest and moorland vegetation on evaporation and streamflow in upland catchments
Plynlimon water balance moorland vegetation vaporation streamflow upland catchments
2009/6/8
The Plynlimon experiment in mid-Wales, designed to determine the extent to which coniferous plantation increases evaporation losses and reduces streamflow relative to upland grassland, has now been yi...
Stream water quality in acid sensitive UK upland areas：an example of potential water quality remediation based on groundwater manipulation
Stream water quality potential water quality groundwater manipulation
2009/6/8
The patterns of variation in water quality for an acidic stream draining plantation forest overlying acidic and acid sensitive gley soils with shale and slate bedrock changed following the introductio...
The occurrence of groundwater in the Lower Palaeozoic rocks of upland Central Wales
groundwater upland Central Wales Lower Palaeozoic rocks
2009/6/8
A series of boreholes of up to 50 m depth, drilled into Lower Palaeozoic mudstone, shale and greywacke bedrock in the headwater catchment areas of the River Severn at Plynlimon in Central Wales, show...
Non-linearity and spatial resolution in a cellular automaton model of a small upland basin
cellular automaton Cam Gill Beck upland basin
2009/6/5
The continuing development of computational fluid dynamics is allowing the high resolution study of hydraulic and sediment transport processes but, due to computational complexities, these are rarely ...
Snow, whilst not a dominant feature of Britain's maritime climate, can exert a significant influence on major floods through its contribution as snowmelt. Flood warning systems which fail to take acco...

2009/5/18
The heterogeneous nature of upland hard-rock catchments in terms of geology, geomorphology, superficial deposits, soil type and land use gives rise to a range of hydrochemical characteristics in strea...
The role of catchment characteristics in determining surface water nitrogen in four upland regions in the UK

2009/5/6
Hydrochemical and catchment data from 80 upland moorland sites in four regions with contrasting climate, soils, geology and geomorphology have been analysed to assess the key catchment attributes that...
Implications of changing from grazed or semi-natural vegetation to forestry for carbon stores and fluxes in upland organo-mineral soils in the UK
semi-natural vegetation carbon stores upland organo-mineral soils
2009/5/6
In the UK, as organo-mineral soils are a significant store of soil organic carbon (SOC), they may become increasingly favoured for the expansion of upland forestry. It is important, therefore, to asse...
