Oxygen dynamics and plant-sediment interactions in isoetid ...

PrefaceThe content of this thesis includes part of the work I have been involved in during the last three year as aPhD-student at the Freshwater Biological Laboratory. Five scientific manuscripts are presented forevaluation. Two are already published in New Phytologist and Plant Signaling and Behavior. The otherthree manuscripts are ready for submission. One additional article published in the Danish magazineURT is also included.In addition to the papers selected for evaluation I am a co-author of two peer reviewed articles and fourarticles published in magazines during my time as a PhD-student. One article addresses the rare slow growingcyanobacterium, Nostoc zetterstedtii (submitted to Limnology & Oceanography), where in-situ growth ratesproved to be the slowest recorded for any aquatic macrophyte. Three other articles arose from our yearly fieldtripsto Öland working with the remarkably inhabitants of the small alvar ponds an environment with constantlychanging temperatures and water levels. One of these articles is published in Svensk Botanisk Tidskrift, theremaining ones in URT. The last article is also published in URT addressing effects of organic enrichment ofsediments on root morphology and plant anchorage.
