1. Pollen-based quantitative reconstruction of land-cover change in Europe from 11,500 years ago until present - A dataset suitable for climate modelling
Abstract : The major objective of this thesis was to produce descriptions of the land vegetation-cover in Europe for selected time windows of the Holocene (6000, 3000, 500, 200, and 50 calendar years before present (BP=1950)) that can be used in climate modelling. Land vegetation is part of the climate system; its changes influence climate through biogeophysical and biogeochemical processes. READ MORE

2. Pollen productivity estimates and pollen-based reconstructions of Holocene vegetation cover in Northern and temperate China for climate modelling
Abstract : Model projections of future climate change require that coupled climate-vegetation models are developed and validated, i.e. these models should be able to reproduce past climate and vegetation change. Records of pollen deposited in lake bottoms and peat bogs can provide the information needed to validate these models. READ MORE

3. Intramolecular isotope analysis reveals plant ecophysiological signals covering multiple timescales
Abstract : Our societies' wellbeing relies on stable and healthy environments. However, our current lifestyles, growth-oriented economic policies and the population explosion are leading to potentially catastrophic degradation of ecosystems and progressive disruption of food chains. READ MORE

4. Nitrogenase localisation reveals cell differentiation in filamentous, non-heterocystous cyanobacteria
Abstract : This thesis deals with detecting and interpreting natural and anthropogenic changes in the composition of the Arctic troposphere. It also covers quantifications of regional climate change due to the activities of mankind. READ MORE

5. Swimming with the current : Fictive locomotion reveals subtle phenotypes in the zebrafish locomotor network
Abstract : Neural networks are the functional building blocks of the central nervous system. To better understand how these networks develop and operate, we turned to the zebrafish locomotor network, with a focus on subtypes of interneurons expressing dmrt3a and wt1a. READ MORE
