1. 11. Composition and dynamics of the bacterial community in aerobic granular sludge reactors

   Författare :Enikö Barbara Szabo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; qPCR; sequencing batch reactors; microbial community composition; T-RFLP; functional groups; Illumina MiSeq; wastewater; aerobic granular sludge; nitrogen removal; population dynamics;

   Sammanfattning : The aerobic granular sludge (AGS) technology is probably the future standard for wastewater treatment, due to its low footprint and low energy consumption. Although achieving granulation is usually not a challenge anymore, our understanding of the community assembly during start-up, and of the microbial ecology of these reactors in general, is incomplete.

3. 12. Community Robustness Analysis : Theoretical Approaches to Identifying Keystone Structures in Ecological Communities

   Författare :Sofia Berg; Tomas Jonsson; Bo Ebenman; Daniel Stouffer; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Most of the world’s ecosystems suffer from stress caused by human activities such as habitat destruction, fragmentation, overexploitation of species and climate change. These factors affect the reproduction and/or survival of individual species as well as interactions between species in ecological communities. LÄS MER

4. 13. Spatial and temporal ecology of oak-associated fungal communities

   Författare :Maria Faticov; Ayco Tack; Peter Hambäck; Paula Baptista; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; abiotic and biotic forces; climate warming; community ecology; foliar fungal community; host genotype; plant microbiome; powdery mildew; seasonal dynamics; warming-by-genotype interaction; Quercus robur; soil fungal community; spatial patterns; ekologi och evolution; Ecology and Evolution;

   Sammanfattning : Plants host a large diversity of microorganisms, which includes fungi, bacteria and archaea. Among these, fungi are highly diverse, and known to play a vital role in plant health and in regulation of the essential ecosystem functions. LÄS MER

5. 14. Bio-based recovery of organic carbon from municipal waste streams : Process optimization and microbial community dynamics

   Författare :Isaac Owusu-Agyeman; Zeynep Cetecioglu; Elzbieta Plaza; Piet Lens; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

   Sammanfattning : Resource recovery from waste contributes to the transition to a sustainable society. Municipal organic wastes have enormous potential for resource recovery due to the inherent organic content which makes it possible to obtain bio-based chemicals and bioenergy. LÄS MER

7. 15. Macroalgal community dynamics on coral reefs : Implications for management

   Författare :Erik Mörk; Nils Kautsky; Magnus Nyström; Tim R. McClanahan; Stein Fredriksen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Coral Reefs; Herbivory; Nutrients; Ecosystem change; Fish; Sea Urchins; East Africa; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : Although rather inconspicuous on healthy coral reefs, macroalgae form the basis of coral food webs. Today, macroalgae are generally increasing and many reefs undergo transitions from coral to macroalgal dominance resulting from e.g. enhanced nutrient loading or increased fishing. LÄS MER
