  2. 1. Seagrass Respiration : An assessment of oxygen consumption patterns of temperate marine macrophytes

    Author : Lina M. Rasmusson; Mats Björk; Martin Gullström; Katharina Pawlowski; Jonas Collén; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mitochondrial respiration; Photorespiration; Seagrass productivity; Zostera marina; Marine carbon budgets; Ruppia maritima; Ulva intestinalis; Plant Physiology; växtfysiologi;

    Abstract : In coastal seas, the abundance of marine macrophytes has profound influence on the flows of oxygen and inorganic carbon through the water. Vast amounts of carbon dioxide are taken up by photosynthesis and part of this is respired back into the water column. READ MORE

  4. 2. Low temperature acclimation in plants : alterations in photosynthetic carbon metabolism

    Author : Maria Lundmark; Vaughan Hurry; Charles Guy; Umeå universitet; []
    Keywords : Plant physiology; cold acclimation; carbon metabolism; photosynthesis; respiration; Växtfysiologi; Physiological Botany; fysiologisk botanik;

    Abstract : Although low temperature plays an important role in determining agricultural yield, little is known about the effect on the underlying biochemical and physiological processes that influence plant growth. Photosynthesis and respiration are central to plant growth and both processes are heavily affected by temperature. READ MORE

  5. 3. Proton pathways in energy conversion : K-pathway analogs in O2- and NO-reductases

    Author : Nathalie Gonska; Pia Ädelroth; Alessandro Giuffré; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; membrane protein; respiration; electron transfer; proton transfer; redox reaction; metalloprotein; non-heme iron; cytochrome ba3; flow-flash; carbon monoxide; liposome; respiratory control ratio; Biochemistry; biokemi;

    Abstract : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.

  6. 4. Explaining temporal variations in soil respiration rates and delta13C in coniferous forest ecosystems

    Author : Daniel Comstedt; Alf Ekblad; Rolf Siegwolf; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Autotrophic; Boreal forest; Elevated CO2; 13C; Natural abundance of stable isotopes; Picea abies; PLS; Root respiration; Soil respiration; Biology; Biologi; Biology; Biologi;

    Abstract : Soils of Northern Hemisphere forests contain a large part of the global terrestrial carbon (C) pool. Even small changes in this pool can have large impact on atmospheric [CO2] and the global climate. READ MORE

  7. 5. Seagrasses in warming oceans : physiological and biogeochemical responses

    Author : Rushingisha George; Mats Björk; Martin Gullström; Teresa Alcoverro Pedrola; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
