  3. 3. Acclimation of plants to combinations of abiotic factors connecting the lab to the field

    Detta är en avhandling från Umeå : Umeå University

    Författare :Zsofia Réka Stangl; Umeå universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogen; carbon dioxide; temperature; thermal acclimation; mycorrhiza; boreal forest; climate change; C:N balance; allocation; respiration; photosynthesis; terrestrial biosphere model;

    Sammanfattning : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. LÄS MER

  4. 4. Modelling the terrestrial carbon cycle – drivers, benchmarks, and model-data fusion

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

    Författare :Zhendong Wu; [2018-09]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Global carbon cycle; Ecosystem modeling; Uncertainty; LPJ-GUESS; Traceability Framework; Model-data fusion; Climate data;

    Sammanfattning : The terrestrial ecosystem sequesters about one-third of anthropogenic emissions each year, thereby providing a critical ecosystem service that slows the rate of increase of atmospheric carbon dioxide and helps mitigate climate change. Observed atmospheric carbon dioxide concentrations exhibit a large inter-annual variability which is considered to be caused primarily by the response of the terrestrial ecosystem to climate change and anthropogenic activity.

  5. 5. The Role of Carbon-Nitrogen Interactions for Terrestrial Ecosystem Dynamics under Global Change - a modelling perspective

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

    Författare :David Wårlind; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C-N Interactions; Ecosystem Modelling; DGVM; Nitrogen; Carbon; Climate Change;

    Sammanfattning : The nature of future climate change will depend on anthropogenic emissions of CO2, as well as climate- and CO2-mediated feedbacks through carbon (C) cycling in both terrestrial ecosystems and oceans. Terrestrial ecosystems remove presently about 25% of the anthropogenic CO2 fossil-fuel and land-use change emissions, but to attribute which mechanisms cause this uptake, and the key regions where it occurs, is a challenging task.
