   Abstract : Introduction: This doctoral thesis in Information Systems disentangles the interplay of an OGD reform and an OGD ecosystem. Open government data (OGD) refers to data shared by public organizations, in the role of providers, following certain principles for anyone to reuse. READ MORE

4. 2. Modelling Evolution : From non-life, to life, to a variety of life

   Author : Yu Liu; David J. T. Sumpter; Peter Dittrich; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Recalling Urban Nature : Linking City People to Ecosystem Services

   Author : Stephan Barthel; Carl Folke; Thomas Elmqvist; Johan Colding; Per Olsson; Susanne Stoll-Kleemann; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecosystem service; functional group; resilience; social-ecological system; urban; institution; property right; knowledge; sense-of-place; social-ecological memory; adaptive governance; scale-crossing broker; ecosystem management; Biology; Biologi; Natural Resources Management; naturresurshushållning;

   Abstract : Societal development is dependent on the generation of ecosystem services (ES) to sustain it; however, many ES are degrading. This thesis investigates how social-ecological features behind practices of actor groups shape the generation of ES. READ MORE

6. 4. Peatland Bryophytes in a Changing Environment : Ecophysiological Traits and Ecosystem Function

   Author : Gustaf Granath; Håkan Rydin; Joachim Strengbom; Steven K Rice; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; allometric scaling; chlorophyll fluorescence; competition; decomposition; flooding; mire; N concentration; nitrogen deposition; photosynthesis; succession; stoichiometry; Ecological Botany; Ekologisk botanik;

   Abstract : Peatlands are peat forming ecosystems in which not fully decomposed plant material builds up the soil. The sequestration of carbon into peat is mainly associated with the bryophyte genus Sphagnum (peat mosses), which dominate and literally form most peatlands. READ MORE

7. 5. Arthropods in Constructed Wetlands : Ecosystem Processes and Riparian Biodiversity

   Author : David Åhlén; Peter Hambäck; Julien Pétillon; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; constructed wetlands; arthropods; community ecology; spiders; insects; hydrology; shoreline properties; primary production; greenhouse gasses; nutrients; grazing management; Ecology and Evolution; ekologi och evolution;

   Abstract : Constructed wetlands in the agricultural landscape are known to harbor immense arthropod biodiversity, however, riparian arthropod communities have often been neglected compared to aquatic communities when studying environmental responses. These wetlands are highly productive, but vary in form and composition based on its purpose, which influences the communities that inhabit them. READ MORE
