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. Importance of bacterial maintenance respiration and baseline respiration for development of coastal hypoxia

   Author : Kevin Vikström; Johan Wikner; Jan Karlsson; Josep M. Gasol; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Respiration; Estuarine; Allochthonous; Maintenance; primary production; bacterial production;

   Abstract : Reduced oxygen concentrations and increasing hypoxic zones havebecome more common in the sea due to climate change andeutrophication. The main cause of oxygen loss in oxygenatedenvironments is respiration. READ MORE

5. 3. Climate Change sensitivity of Photosynthesis and Respiration in Tropical Trees

   Author : Myriam Mujawamariya; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon dioxide; Climate change; Drought; Elevation gradient; Photosynthesis; Respiration; Tropical montane forest; Tropical trees; Warming;

   Abstract : Tropical climate is getting warmer, with more pronounced dry periods in large areas. The productivity and climate feedbacks of future tropical forests depend on the ability of trees to acclimate their physiological processes, such as photosynthesis and leaf respiration, to these new conditions.

6. 4. Nocturnal enuresis and rapid maxillary expansion : – long-term effect, prognostic variables, respiration during sleep and quality of life

   Author : Ingrid Jönson Ring; Bazargani Farhan; Tryggve Nevéus; Agneta Markström; Maria Ransjö; Uppsala universitet; []
   Keywords : Rapid maxillary expansion; nocturnal enuresis; sleep disordered breathing; respiration; polygraphic sleep recording; quality of life.; Medicinsk vetenskap; Medical Science;

   Abstract : Background:The orthodontic technique rapid maxillary expansion (RME) has been reported to have a potentially curative effect on nocturnal enuresis (NE). The mechanism behind this is unknown but could possibly be due to placebo and/or effects on respiration during sleep. READ MORE

7. 5. 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
