  1. 1. Modelling Evolution From non-life, to life, to a variety of life

    Detta är en avhandling från Uppsala : Department of Mathematics

    Författare :Yu Liu; Uppsala universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical biology; Biocomplexity; Artificial chemistry; Ecosystem evolution; Origin of life; Self-replication; Prebiotic evolution; Collectively-catalytic; Golden ratio; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Sammanfattning : Life is able to replicate itself, e.g., a microorganism is able to divide into two identical ones, and a single plant is able to forest a whole island. LÄS MER

  2. 2. Element transport in aquatic ecosystems – Modelling general and element-specific mechanisms

    Detta är en avhandling från Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Författare :Lena Konovalenko; Stockholms universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radionuclides; elements; concentration ratio; bioaccumulation; biomagnification; fish; modelling; aquatic food web; ecosystem; Cs; Sr; environmental risk assessment; Marine Ecotoxicology; marin ekotoxikologi;

    Sammanfattning : Radionuclides are widely used in energy production and medical, military and industrial applications. Thus, understanding the behaviour of radionuclides which have been or may be released into ecosystems is important for human and environmental risk assessment. LÄS MER

  3. 3. Linking distributed hydrological processes with ecosystem vegetation dynamics and carbon cycling: Modelling studies in a subarctic catchment of northern Sweden

    Detta är en avhandling från Department of Physical Geography and Ecosystem Science, Lund University

    Författare :Jing Tang; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon cycling; Water cycling; Hydrological modelling; Ecosystem modelling; Subarctic ecosystems; Climate change;

    Sammanfattning : The Arctic and Subarctic regions are of particular importance to the global climate change and are now experiencing a climate warming that is higher than the global average. Around 50% of the global soil carbon is stored in high latitude soils, especially in permafrost and peatland soils. LÄS MER

  4. 4. Towards an integrated ecology through mechanistic modelling of ecosystem structure and functioning

    Detta är en avhandling från Geobiblioteket, Lunds Universitet, Sölvegatan 12, SE-22362 Lund, Sweden

    Författare :Thomas Hickler; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; geomorphology; Physical geography; integrated ecology; plant hydraulic architecture; climate change; CO2 fertilisation effect; biogeography; biogeochemistry; vegetation dynamics; ecosystem modelling;

    Sammanfattning : Plant physiology, population dynamics and the structure and functioning of ecosystems are closely interrelated. However, these processes are often investigated independently within different subdisciplines of ecology. LÄS MER

  5. 5. Biophysical and Human Controls of Land Productivity under Global Change : Development and Demonstration of Parsimonious Modelling Techniques

    Detta är en avhandling från Lund University, Faculty of Science, Department of Physical Geography and Ecosystem Science

    Författare :Florian Sallaba; [2016-11]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecosystem Modelling; Meta-modelling; Net Primary Production; Global Change; Model coupling;

    Sammanfattning : Net primary production (NPP) serves as an indicator for plant-based resources such as food, timber and biofuel for human appropriation. It is defined by the annual production of plant matter and is mainly controlled by climate and human activities. Climate change in combination with human activities is altering NPP. LÄS MER
