2. 1. Functional Traits in Sphagnum

   Author : Fia Bengtsson; Håkan Rydin; Gustaf Granath; Cronberg Nils; Sari Juutinen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; peat mosses; functional traits; NPP; decay resistance; N2 fixation; desiccation resistance; climate; Biology with specialization in Ecological Botany; Biologi med inriktning mot ekologisk botanik;

   Abstract : Peat mosses (Sphagnum) are ecosystem engineers that largely govern carbon sequestration in northern hemisphere peatlands. I investigated functional traits in Sphagnum species and addressed the questions: (I) Are growth, photosynthesis and decomposition and the trade-offs between these traits related to habitat or phylogeny?, (II) Which are the determinants of decomposition and are there trade-offs between metabolites that affect decomposition?, (III) How do macro-climate and local environment determine growth in Sphagnum across the Holarctic?, (IV) How does N2 fixation vary among different species and habitats?, (V) How do species from different microtopographic niches avoid or tolerate desiccation, and are leaf and structural traits adaptations to growth high above the water table?Photosynthetic rate and decomposition in laboratory conditions (innate growth and decay resistance) were related to growth and decomposition in their natural habitats.

4. 2. Regulation of insulin producing cells, stress responses and metabolism in Drosophila

   Author : Neval Kapan; Dick R. Nässel; Alberto Ferrus; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insulin signaling; Drosophila melanogaster; peptide hormones; neuropeptides; GABA; funktionell zoomorfologi; Functional Zoomorphology;

   Abstract : In Drosophila, neuropeptides have regulatory roles in development, growth, metabolism and reproduction. This study focused on GABA and the neuropeptides Drosophila tachykinin (DTK), short neuropeptide F (sNPF), adipokinetic hormone (AKH), corazonin (CRZ) and Drosophila insulin-like peptides (DILPs) as possible regulators of metabolic stress responses and homeostasis.

5. 3. Exploring the functionality of coconut proteins

   Author : Borges Chambale; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coconut; coconut milk; extraction; proteins; emulsions; functional properties; denaturation; gels; yield stress; glass structure;

   Abstract : At present, coconut proteins are discarded as a waste product by the coconut oil industry. If the range of applications of coconut proteins is to be expanded, their potential functionalities should be investigated. Emulsions and gels are of the greatest interest in food industry. READ MORE
