  1. 1. Effect of elevated pCO2 and environmental oxazepam on the behavior and physiology of teleost fish

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Laura E. Vossen; Svante Winberg; Robert Gerlai; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fish; GABA; CO2; ocean acidification; pharmaceutical pollution; oxazepam;

    Abstract : This doctoral thesis investigated the effect of two aquatic pollutants on the behavior and physiology of teleost fish: i) elevated concentrations of carbon dioxide (CO2) in the context of ocean acidification and ii) low concentrations of the anxiolytic pharmaceutical oxazepam in the context of pharmaceutical pollution.Anthropogenic emissions of CO2 are lowering the pH of the oceans.

  2. 2. Seagrass productivity from plant to system

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Diana Deyanova; Mats Björk; Mirta Teichberg; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Seagrass; Chlorophyll a fluorescence; Ageing; Productivity; Seasonality; Stress response; växtfysiologi; Plant Physiology;

    Abstract : Seagrasses form one of the most productive habitats on earth and are recognized as very efficient carbon sinks. The levels and patterns of productivity within and across different seagrass systems vary widely due to natural or human-induced factors. READ MORE

  3. 3. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways

    University dissertation from Lund University Department of Cell and Organism Biology Sölvegatan 35B SE-223 62 Lund

    Author : Daniela Geisler; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzymology; Proteins; Kärlväxters fysiologi; Physiology of vascular plants; Växtekologi; Plant ecology; Växtbiokemi; Plant biochemistry; respiratory chain; plant mitochondria; nitrogen; NADPH dehydrogenase; NADH dehydrogenase; alternative oxidase; calcium; Proteiner; enzymologi; Bioenergetics; Bioenergetik; Lipids; steroids; membranes; Lipider; steroider; mebran;

    Abstract : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. READ MORE

  4. 4. The actinorhizal plant Datisca glomerata interpreting its symbiotic adaptations by omics-based comparisons with model and non-model organisms

    University dissertation from Stockholm University : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Marco Salgado; Katharina Pawlowski; Daniel Lundin; Rene Geurts; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Root nodule symbiosis; nitrogen fixation; actinorhizal; Datisca glomer-ata; Frankia; nodule development; defensin; antimicrobial; carboxylate transporter; phylogenomics; transcriptomics; växtfysiologi; Plant Physiology;

    Abstract : Nitrogen is the element that most often limits plant growth and development. Common agricultural practices rely on the application of large quantities of industrially-produced nitrogen fertilizer, which poses a worldwide environmental threat. Sustainable agriculture encourages the use of biologically fixed nitrogen. READ MORE

  5. 5. The circadian clock in annuals and perennials coordination of Growth with Environmental Rhythms

    University dissertation from Umeå : Umeå Universitet, Institutionen för fysiologisk botanik

    Author : Mikael Johansson; Umeå universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; circadian clock; arabidopsis; populus; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; TECHNOLOGY Bioengineering Plant biotechnology; TEKNIKVETENSKAP Bioteknik Växtbioteknik; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; molekylärbiologi; Molecular Biology;

    Abstract : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. READ MORE
