  2. 1. Iodine Isotopes (129I and 127I) in the Baltic Sea   : Tracer applications & environmental impact

    Author : Peng Yi; Ala Aldahan; Glen Snyder; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; radioactive 129I; stable 127I; AMS; iodine species; nuclear reprocessing facilities; tracers; Baltic Sea; circulation; water exchange; environmental impact;

    Abstract : 129I is a radioactive isotope (T1/2= 15.7 million years) produced through natural and anthropogenic pathways, but the anthropogenic production is presently dominating the Earth’s surface environments. 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. A palaeolimnological study of the anthropogenic impact on dissolved organic carbon in South Swedish lakes

    Author : Petra Bragée; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DOC; Brownification; Landscape Reconstruction Algorithm; Land-use changes; Lake sediments; Anthropogenic impact;

    Abstract : During the past three decades, increases have been observed in dissolved organic carbon (DOC) concentrations and colour in the surface waters of lakes and rivers in parts of Europe and North America, raising concern about the effects on the quality of aquatic environments with consequences for biodiversity, resource availability and recreational use. Various hypotheses have been put forward to explain the recent increases in DOC concentration and numerous studies have been published linking them to declining anthropogenic atmospherically deposited sulphur.

  6. 4. 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

  7. 5. Anthropogenic impact on predator guilds and ecosystem processes : Apex predator extinctions, land use and climate change

    Author : Marianne Pasanen Mortensen; Bodil Elmhagen; Francisco Palomares; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mesopredators; apex predators; top-down; bottom-up; interspecific killing; red fox; Eurasian lynx; grey wolf; wolverine; productivity; winter severity; cropland; zoologisk ekologi; Animal Ecology;

    Abstract : Humans affect ecosystems by changing species compositions, landscape and climate. This thesis aims to increase our understanding of anthropogenic effects on mesopredator abundance due to changes in apex predator status, landscape and climate. READ MORE
