  2. 21. Nitrogen removal by wetlands in a cold climate : understanding interactions between macrophytes and microorganisms

    Author : Maidul Choudhury; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nitrogen (N), a fundamental component of living organisms, has become one of the main global concerns for human society due to the myriad of negative effects of excessive N on ecosystems. Anthropogenic activities such as agriculture, industrial production, urbanisation and mining are major sources of N to freshwaters. READ MORE

  4. 22. On the conditions for developing hunting and fishing tourism in Sweden

    Author : Anders Kagervall; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : In many rural areas industrial development have reduced the number of available jobs in traditional industries such as agriculture and forestry. Areas that historically have been dependent on extraction of resources, experience a reduced need for labor. In some areas the result is high unemployment and depopulation. READ MORE

  5. 23. Contested Landscapes : social-ecological interactions between forestry and reindeer husbandry

    Author : Tim Horstkotte; Jon Moen; Camilla Sandström; Micheline Manseau; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Reindeer husbandry; forestry; adaptive capacity; arboreal lichens; snow; winter pasture; natural resource management; multiple use; land-use conflict; habitat fragmentation;

    Abstract : Throughout northern Fennoscandia, reindeer husbandry is a central part in the cultural heritage of the Sámi people. In its history, Sámi culture and reindeer husbandry have undergone significant adaptations to environmental, social and political challenges. READ MORE

  6. 24. Nutrient Transfer in Aquaponic Systems – Optimizing microbial processes for greater circularity and economic viability

    Author : Victor P. Lobanov; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aquaculture; Aquaponics; Controlled environment agriculture; Waste revalorization; Microbiology;

    Abstract : The trend towards sustainable process design in modern industries combines the goal of improving process efficiency with a conscientious shift towards resource conservation. Aquaponics, a system that involves co-cultivating fish and plants, is a waste-conscious food production system. READ MORE

    Abstract : Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. READ MORE
