  2. 1. The Earth : climate and anthropogenic interactions in a long time perspective

    Author : Jörgen Olofsson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anthropogenic; climate change; land use; biodiversity; carbon; dynamic global vegetation model; Holocene; pre-industrial; pollen; bison;

    Abstract : The Earth is a highly complex and dynamic system. Life has shaped the entire planet and evolved in response to living conditions. Ecosystems are heavily affected by climate. Rapidly changing conditions imply considerable stress on several species and ecosystems, as well as to the most dominant species on the planet. READ MORE

  4. 2. Analysis of the impact of anthropogenic pollution on shallow groundwater in peri-urban Kampala

    Author : Robinah Kulabako; Roger Thunvik; Mai Nalubega; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shallow groundwater; Sanitation; Peri-urban; Vadose zone; Anthropogenic; Modelling; Environmental engineering; Miljöteknik;

    Abstract : An investigation to assess the anthropogenic pollutant loads, transport and impact on shallow groundwater in one of Kampala’s peri-urban areas (Bwaise III Parish) was undertaken. Bwaise III is a densely populated informal settlement with a high water table (... READ MORE

  5. 3. Application of Passive DOAS using Scattered Sunlight for quantification of gas emissions from anthropogenic and volcanic sources

    Author : Claudia Rivera; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nitrogen dioxide; DOAS; gas emission; sulphur dioxide; volcanic; formaldehyde.; scattered sunlight; anthropogenic;

    Abstract : Monitoring of gas emissions from natural and anthropogenic sources is important due to the negative effects of these emissions on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. READ MORE

  6. 4. Nesting ecology of the grass snake (Natrix natrix) and its implications for conservation

    Author : Kristin Löwenborg Di Marino; Mattias Hagman; Sören Nylin; Tobias Uller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; agriculture; anthropogenic; climate; embryonic development; incubation; zoologisk ekologi; Animal Ecology;

    Abstract : The onset of agriculture about 12,000 years ago has had a major influence on the biodiversity of plants and animals. Unfortunately, the rapid changes in agricultural practices that has occurred in recent times has negatively affected many farmland species. READ MORE

  7. 5. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds

    Author : Epameinondas Tsiligiannis; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VOC; anthropogenic; biogenic; SOA; atmospheric oxidation; organic aerosols; CIMS; FIGAERO; TMB; isoprene; HOM; organonitrates ONs ; NOx; OH; nitrate NO3 ; Go:PAM; SAPHIR;

    Abstract : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. READ MORE
