1. The Greenhouse - Icehouse Transition : a dinoflagellate perspective
Sammanfattning : Through the analysis of the stratigraphic and spatial distribution of organic walled dinoflagellate cysts (dinocysts) from climatologically and oceanographically key sites, this project aims to contribute to a better understanding of the Eocene-Oligocene (E/O) environmental changes and their timing. A central issue is to identify the global environmental changes which are responsible for the Eocene cooling and its underlying mechanisms with the focus on the Oligocene isotope-1 (Oi-1) event, thought to mark the onset of major Antarctic glaciation.

2. Grazer-induced responses in marine phytoplankton
Sammanfattning : Phytoplankton are the most important primary producers in the world’s oceans, yet little is known of how they avoid the constant threats from the pelagic grazers. From land it is well known that plants defend themselves by having thorns or producing compounds unpalatable to grazers. LÄS MER

4. Influence of Human-induced Environmental Changes on the Physiology of the Harmful Benthic Marine Microalga Ostreopsis ovata
Sammanfattning : This thesis focus on the influence of human-induced environmental changes on the physiology of Ostreopsis ovata; a toxic, benthic dinoflagellate, which form blooms in tropical and temperate marine waters. O. LÄS MER
5. Dinoflagellate studies of the Upper Maastrichtian and Danian in southern Scandinavia
Sammanfattning : Three Swedish borehole cores and three Danish outcrop sections, spanning the Upper Maastrichtian and Danian, have been analyzed for dinoflagellates. Variations in the relative abundances of certain dinoflagellate species have been used to establish a quantitatively defined, high-resolution zonation for the Upper Maastrichtian of southern Scandinavia.
