  1. 1. Functional Traits in Sphagnum

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fia Bengtsson; Uppsala universitet.; [2019]
    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.

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

    University dissertation from Stockholm, Sweden : Department of Zoology, Stockholm Univeristy

    Author : Neval Kapan; Stockholms universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insulin signaling; Drosophila melanogaster; peptide hormones; neuropeptides; GABA; Functional Zoomorphology; funktionell zoomorfologi;

    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.

  3. 3. Exploring the functionality of coconut proteins

    University dissertation from Department of Food Technology, Engineering and Nutrition, Lund University

    Author : Borges Chambale; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coconut; coconut milk; extraction; proteins; emulsions; functional properties; denaturation; gels; yield stress; glass structure;

    Abstract : Popular Abstract in English The potential of coconut proteins as food ingredients was studied with the aim of evaluating how plant proteins, in particular those from coconut, could find industrial applications and compete with proteins of animal origin based on meat, fish, milk or eggs. Three research directions were chosen for investigation, to evaluate how coconut proteins would perform in each of the following situations: Would coconut proteins be able to keep stable oil in water dispersions (emulsions), as in cows’ milk? Do coconut proteins stiffen when heated, like when an egg is boiled? Does full-fat coconut milk, heat-treated and homogenised, behave like mayonnaise, showing some initial resistance to flow under stress? These questions address important issues, as they can provide a general picture regarding the potential of coconut proteins for further investigation. READ MORE
