2. 1. Microbial Communities in Boreal Peatlands : Responses to Climate Change and Atmospheric Nitrogen and Sulfur Depositions

   Author : Magalí Martí Genero; Bo Svensson; Åsa Danielsson; Torben Christensen; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Microbial communities; methanogens; plant communities; peatland; temperature; nitrogen; long-term; field experiment; high-throughput sequencing; Microbiella samhällen; metanogener; växtsamhällen; myrar; torv; temperatur; kväve; långtid; fältexperiment; high-throughput-sekvensering;

   Abstract : Myrmarker har en stor roll i regleringen av den globala kolbalansen och koncentrationerna av koldioxid och metan i atmosfären, vilket gör dem till speciellt viktiga ekosystem ur ett klimatförandringsperspektiv. Förändringar av myrmarker genom naturlig utveckling eller antropogen påverkan kan därför få långtgående störningar av myrars klimatreglerande funktion. READ MORE

4. 2. Regeneration measures in time and space : Site preparation, planting and digital tools

   Author : Per Nordin; Karin Hjelm; Erika Olofsson; Nelson Thiffault; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Betula pendula; microsite; Picea abies; Pinus contorta; Pinus sylvestris; planting; regeneration; site preparation; remote sensing; Betula pendula; mikromiljö; Picea abies; Pinus contorta; Pinus sylvestris; föryngring; plantering; markberedning; fjärranalys; Technology byts ev till Engineering ; Teknik;

   Abstract : Regeneration success depends on decisions made based on factors on aregional, site, and microenvironmental level. Therefore, understanding andmapping of such factors between and within sites can guide decisions forbetter seedling establishment. READ MORE

5. 3. Effects of solar radiation on the abiotic and bacterially mediated carbon flux in aquatic ecosystems

   Author : Alexandre Magno Anesio; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bacteria; dissolved inorganic carbon DIC ; bioavailability; aquatic macrophytes; photooxidation; detritus decomposition; Ultraviolet radiation; dissolved organic carbon DOC ; fungi; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

   Abstract : In this Thesis, I studied some of the current aspects of organic matter photochemistry. I analyzed abiotic phototransformations of several types of dissolved (DOM) and particulate organic matter (POM). I also evaluated the effects of phototransformation of several types of DOM on bacteria. READ MORE

6. 4. A multi-resolution approach for modeling flow and solute transport in heterogeneous porous media

   Author : Hrvoje Gotovac; Vladimir Cvetkovic; Alberto Bellin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-resolution adaptive approach; Atomic and Fup basis functions; Monte- Carlo method; Heterogeneous porous media; Flow; Transport; Travel time; Water engineering; Vattenteknik;

   Abstract : Subsurface processes are usually characterized by rare field experiments, sparse measurements,multi-resolution interpretations, stochastic description, related uncertainties and computational complexity. Over the last few decades, different computational techniques and strategies have become indispensable tools for flow and solute transport prediction in heterogeneous porousmedia. READ MORE

7. 5. Soil Remediation and Sustainable Development : Creating Appropriate Solutions for Marginalized Regions

   Author : Henrik Haller; Anders Jonsson; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The scope of this doctoral thesis is appropriate soil remediation methods for marginalized regions that go beyond pollution reduction targets and include strategies to support sustainable development. Contaminated soil from industrial or agricultural activities poses potential health threats to animals and humans and also threatens economic systems by making land unsuitable for agriculture and other economic purposes.
