Seagrass Respiration An assessment of oxygen consumption patterns of temperate marine macro- phytes

Abstract

List of papers This thesis is a compilation of four manuscripts that will be referred to by their roman numerals. I Rasmusson LM, Björk M (2014) Determining light suppression of mitochondrial respiration for three temperate marine macrophytes using the Kok method. Respiratory oxygen consumption in the seagrass Zostera marina is affected by light and varies on a diel basis: a combined gas exchange and gene expression study. (Manuscript) III Rasmusson LM, Gullström M, Björk M. Effects of increased temperature on respiration and photosynthesis differ among different leaf parts and with tissue age of the seagrass Zostera marina. (2013) Photorespiration and carbon limitation determine productivity in temperate seagrasses. My contribution to the papers: Paper I: Planning the study, analysing data and writing the paper with co-author, performing all experiments. Paper II: Planning the study, performing experiments (CL helped with gene expression analyses), analysing data and writing the paper with co-authors. Paper III: Planning the study, analysing data and writing the paper with co-authors, performing all experiments. Paper IV: Participated in planning and in performing the experiments and writing together with co-authors.
