INVASIVE SPECIES AND PANNE ECOSYSTEMS: THE EFFECTS OF ATMOSPHERIC POLLUTION
invasive species nutrients
2015/1/16
Pannes are rare intradunal wetlands. Though small, they are known to exhibit extremely diverse and sensitive vegetation and are home to a number of reptile and amphibian species. In the United States,...
Effects of Acid Precipitation on a Small Acid Lake in Southern Norway
Acid Precipitation Small Acid Lake Southern Norway
2009/10/29
Langtjern is an acid lake situated in south-central Norway, 516 m above sea level.
The watershed is underlain by biotite gneisses and granites. Coniferous forests
cover 63% of the watershed, while 1...
Effects of Land Use on the Diffuse Load of Phosphorus and Nitrogen
Land Use Diffuse Load Phosphorus Nitrogen
2009/10/28
The diffuse load of phosphorus and nitrogen was studied in 23 small drainage
basins in different parts of Finland between 1965 and 1974. Total phosphorus
and total nitrogen concentrations were analy...
Mixing Effects of Carbonate Dissolving Waters on Chemical and 13C/12C Compositions
Mixing Effects Carbonate Dissolving Waters 13C/12C Compositions
2009/10/27
Seasonal variations in chemistry and r1atios o f total inorganic carbon of
carbonate dissolving waters are considered in the frame-work of a simplified
approach dealing explicitly with major ionic s...
Modelling the Effects of Acid Deposition:Estimation of Long-Term Water Quality Responses in Forested Catchments in Finland
Acid Deposition Long-Term Water Quality Responses Forested Catchments
2009/10/27
A modelling study has been undertaken to investigate long-term changes in
surface water quality in two contrasting forested catchments; Yli-Knuutila, with
high concentrations of base cations and sul...
Modelling the Effects of Acid Sulphate Soils on River Acidity in Finland
Effects of Acid Sulphate Soils River Acidity
2009/10/26
Acid sulphate (AS) soils cover extensive areas of the coastal plains in western
Finland. These soils constitute an environmental hazard due to their ability to
relcase acidity when exposed to atmosp...
Seasalt Effects on the Acid Neutralizing Capacity of Streamwaters in Southern Norway
Seasalt Effects Acid Neutralizing Capacity Southern Norway
2009/10/26
Input of neutral salt, primarily NaCI, from sea spray is an important factor for shortterm
acidification of surface water, primarily in already acidified areas, because Na
may substitute for H+ and ...
HYDROCHEMICAL CHARACTERISTICS OF THE JORDAN AND YARMOUK RIVERS：EFFECTS OF NATURAL AND HUMAN ACTIVITIES
Water chemistry HYDROCHEMICAL CHARACTERISTICS Jordan Rivers Yarmouk Rivers
2009/10/13
Water chemistry was used to assist in understanding the effect of human and natural activities on the Jordan and Yarmouk Rivers. Eighty-eight water samples were collected from different locations alon...
Modelling the ecosystem effects of nitrogen deposition：Model of Ecosystem Retention and Loss of Inorganic Nitrogen
nitrogen deposition Ecosystem Retention
2009/6/8
A catchment-scale mass-balance model of linked carbon and nitrogen cycling in ecosystems has been developed for simulating leaching losses of inorganic nitrogen. The model (MERLIN) considers linked bi...
A two-layer application of the MAGIC model to predict the effects of land use scenarios and reductions in deposition on acid sensitive soils in the UK
acid soils UK Acid Waters Monitoring Network
2009/6/5
A two-layer application of the catchment-based soil and surface water acidification model, MAGIC, was applied to 21 sites in the UK Acid Waters Monitoring Network (AWAMN), and the results were compare...
Modelling the effects of climate on long-term patterns of dissolved organic carbon concentrations in the surface waters of a boreal catchment
Dissolved organic carbon artificial neural networks
2009/4/29
Dissolved organic carbon concentrations ([DOC]) in surface waters are increasing in many regions of Europe and North America. These increases are likely driven by a combination of changing climate, r...
Effects of decreasing acid deposition and climate change on acid extremes in an upland stream
climate change upland stream acid deposition
2009/4/29
This study assesses the major chemical processes leading to acid extremes in a small, moorland stream in mid-Wales, UK, which has been monitored since 1979. Results suggest that base cation (mainly ca...
