  2. 1. Myc-induced Lymphomagenesis : In vivo assessment of downstream pathways

    Author : Sara Rimpi; Jonas Nilsson; Juha Klefström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Myc; lymphomagenesis; Aurora kinases; polyamine; glycolysis; targeting; mouse models of cancer; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Myc oncogenes encode transcription factors that bind to E-box sequences in DNA, driving the expression of a large number of target genes and are deregulated in approximately 70% of human cancers. Deregulated Myc expression cause enhanced proliferation (which is counteracted by apoptosis), angiogenesis and cancer. READ MORE

  4. 2. Molecular mechanisms involved in prokaryotic cycling of labile dissolved organic matter in the sea

    Author : Benjamin Pontiller; Jarone Pinhassi; Daniel Lundin; Catherine Legrand; Martin F. Polz; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bacteria and archaea; labile dissolved organic matter; metatranscriptomics; monomers; polymers; carbohydrate-active enzymes CAZymes ; peptidases; membrane transporters; Natural Science; Naturvetenskap; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Abstract : Roughly half of the global primary production originates from microscopic phytoplankton in marine ecosystems, converting carbon dioxide into organic matter. This organic matter pool consists of a myriad of compounds that fuel heterotrophic bacterioplankton. READ MORE

  5. 3. Climate change time machine : Adaptation to 30 years of warming in the Baltic Sea

    Author : Friederike Ermold; Anssi Laurila; Jukka Jokela; Kerstin Johannesson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; thermal adaptation; evolution; Baltic Sea; Biotest Basin; ecological interactions; biological invasions; phenotypic plasticity; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Earth mean surface temperature has increased by 1 °C since the industrial revolution, and this has already had considerable effects on animal and plant species. Ecological responses to the warming climate – often facilitated via phenotypic plasticity – are ubiquitous. READ MORE

  6. 4. Carbon Dioxide in Inland Waters : Drivers and Mechanisms Across Spatial and Temporal Scales

    Author : Anna Cecilia Nydahl; Gesa A. Weyhenmeyer; Marguerite Xenopoulos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon dioxide; dissolved organic carbon; inland water; lake; stream; groundwater; mesocosm; carbonate system; carbon; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Inland waters are an essential component of the global carbon cycle as they are very active sites for carbon transformation processes. Much of this carbon is transformed into the greenhouse gas carbon dioxide (CO2) and emitted into the atmosphere. READ MORE

  7. 5. Structure and Stability of Ecological Networks : The role of dynamic dimensionality and species variability in resource use

    Author : David Gilljam; Bo Ebenman; Peter Münger; José Montoya; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The main focus of this thesis is on the response of ecological communities to environmental variability and species loss. My approach is theoretical; I use mathematical models of networks where species population dynamics are described by ordinary differential equations. READ MORE
