  1. 1. Seagrasses in warming oceans : physiological and biogeochemical responses

    Författare :Rushingisha George; Mats Björk; Martin Gullström; Teresa Alcoverro Pedrola; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Global warming; greenhouse gas; warming oceans; temperate; tropical; coastal waters; Western Indian Ocean WIO ; tidal variability; seagrass; photosynthesis; respiration; photorespiration; biogeochemical processes; sulphide; methane; nitrous oxide; carbon dioxide; Plant Physiology; växtfysiologi;

    Sammanfattning : The exponential increase of atmospheric greenhouse gas concentrations over the past 50 years has caused a rise in the global average temperature by more than 1ºC above pre-industrial levels. Ninety-three percent of this heat energy has been absorbed and stored by the oceans, increasing their temperatures, particularly in surface waters. LÄS MER

  4. 3. Ecosystem processes and biodiversity : theoretical studies and experiments with an aquatic model ecosystem

    Författare :Jon Norberg; Michael L Pace; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Systems Ecology; systemekologi;

    Sammanfattning : Today, human enterprise has implications for all of nature, from the well being of the smallest organism, to the alteration of global biogeochemical cycles. To understand how major ecosystem processes are affected by environmental changes and decreasing biodiversity is crucial as many of natures services depend of such processes. LÄS MER

    Sammanfattning : Forests in Sweden are undergoing rapid and considerable changes regarding both management methods and environmental conditions. To understand the effects of these changes and to be able to predict impending changes in forest ecosystems, a holistic understanding of the processes governing the ecosystem is needed. LÄS MER
