2. 21. Functional and structural characterizations of phytoplankton-bacteria interactions in response to environmental challenges

   Author : Eva Sörenson; Catherine Legrand; Elin Lindehoff; Jarone Pinhassi; Sonya Dyhrman; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interactions; phytoplankton; microalgae; bacteria; communities; aquatic; diversity; functions; structure; species-specific; microbiome; core microbiome; response diversity; resilience; resource partitioning; competition; coexistence; amplicon sequencing; metatranscriptome; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

   Abstract : Microorganisms, such as phytoplankton and bacteria, make up ≈70% of aquatic biomass and contribute 50-85% of the oxygen in Earth’s atmosphere. The microbial loop concept and the discovery of the large diversity in microbial communities acknowledge that biotic interactions between microorganisms in addition to resource competition enable the recycling of energy and nutrients in aquatic food webs.

5. 23. Superantigens in group A streptococcus : gene diversity and humoral immune response

   Author : Linda Maripuu; Mari Norgren; Susan Hollingshead; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Group A streptococcus; Streptococcus pyogenes; superantigen SAg ; SAg-gene profile; M-protein; emm-genotype; biomedicinsk laboratorievetenskap; biomedical laboratory science;

   Abstract : Group A streptococcus (GAS) is a strictly human pathogen that causes infections ranging from asymptomatic carriage to the highly lethal streptococcal toxic shock syndrome (STSS). GAS are classified according to the sequence of the variable 5’ end of the emm-gene that encodes the surface associated M-protein. READ MORE

6. 24. A rational response to natural disasters? : Explaining the global rise of regional disaster risk management

   Author : Simon Hollis; Hertie School of Governance; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; World Society Theory; Comparative Regionalism; Disaster Risk Reduction; Neoliberal Institutionalism; Analytical Eclecticism;

   Abstract : Natural disasters pervade the certainty of social life. In a globalized world this truism increasingly calls for transnational solutions to prevent, prepare, and respond to these deadly disruptions. Regional Disaster Risk Management (DRM) has recently emerged to meet this concern. READ MORE

7. 25. Soil salinity as a driver of microbial community structure and functioning

   Author : Kristin Rath; MEMEG; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil salinization; Soil Microbiology; soil microbial community; Bacteria; Aerobic; Fungi; Drying-rewetting; Microbial growth; Microbial biomass; Soil respiration; salinity tolerance; Saline soils; Salinity gradient;

   Abstract : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.
