  1. 1. Land use effects on greenhouse gas emissions from boreal inland waters

    Author : Marcus Klaus; Jan Karlsson; Peter Staehr; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; greenhouse gas; boreal forest; carbon cycling; whole-ecosystem experiment; limnology; metabolism; forest clearcutting; nitrogen enrichment;

    Abstract : Anthropogenic activities perturb the global carbon and nitrogen cycle with large implications for the earth’s climate. Land use activities deliver excess carbon and nitrogen to aquatic ecosystems. In the boreal biome, this is mainly due to forestry and atmospheric deposition. READ MORE

  2. 2. Antimicrobials in sewage treatment plants : occurrence, fate and resistance

    Author : Marcus Östman; Mats Tysklind; Jerker Fick; Erik Björn; Klaus Kümmerer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

    Abstract : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. READ MORE

  3. 3. Is the Intuitive Statistician Eager or Lazy? : Exploring the Cognitive Processes of Intuitive Statistical Judgments

    Author : Marcus Lindskog; Anders Winman; Peter Juslin; Klaus Fiedler; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Lazy intuitive statistician; Eager intuitive statistician; Intuitive statistics; Sampling model; Numerical cognition; Psychology; Psykologi;

    Abstract : Numerical information is ubiquitous and people are continuously engaged in evaluating it by means of intuitive statistical judgments. Much research has evaluated if people’s judgments live up to the norms of statistical theory but directed far less attention to the cognitive processes that underlie the judgments. READ MORE

  4. 4. Factors regulating the origin and magnitude of carbon dioxide emissions from high-latitude lakes

    Author : Hendricus Verheijen; Jan Karlsson; Cristian Gudasz; David A. Seekell; Marcus Klaus; Anne Ojala; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lake; carbon dioxide; organic carbon; inorganic carbon; arctic; emission; environmental science; miljövetenskap; climate change; klimatförändringar; Physical Geography; naturgeografi;

    Abstract : Lake ecosystems receive, transmit and process terrestrial carbon and thereby link terrestrial, aquatic and global carbon cycles. Most lakes evade CO2 to the atmosphere, but the annual magnitude of CO2 evasion, as well as sources and mechanisms underpinning CO2 evasion from lakes are still largely unresolved. READ MORE
