1. Dialogue and revolution : fostering legitimate stakeholder agency in natural resource governance
Sammanfattning : This thesis explores how people exert their agency in policy processes that pertain to natural resource governance, and how they construct the required sense of legitimacy for such actions. It also examines the manner in which facilitated multi-stakeholder processes foster legitimate stakeholder agency, and reflects on how they may ensure the rigour of research interventions in situations characterised by intractable uncertainty and controversy.

2. Integrative Medicine in the Dutch healthcare system : prerequisites and tools for implementation
Sammanfattning : Integrative Medicine (IM) is a care approach that focuses on the overall well-being and healing process of patients rather than solely on their disease. IM educates and empowers people to be active players in their own care, emphasizes the therapeutic relationship, and makes use of all appropriate evidence-based approaches. LÄS MER
3. Genomic and morphological diversity of marine planktonic diatom-diazotroph associations : a continuum of integration and diversification through geological time
Sammanfattning : Symbioses between eukaryotes and nitrogen (N2)-fixing cyanobacteria (or diazotrophs) are quite common in the plankton community. A few genera of diatoms (Bacillariophyceae) such as Rhizosolenia, Hemiaulus and Chaetoceros are well known to form symbioses with the heterocystous diazotrophic cyanobacteria Richelia intracellularis and Calothrix rhizosoleniae.

4. Environmental conditions governing the distributions of symbiotic and free-living diazotrophic cyanobacteria in two tropical open oceans
Sammanfattning : Di-nitrogen (N2) fixation plays a crucial role in oceanic carbon and nitrogen cycles and is important for marine biogeochemistry on regional and global scales. N2-fixing (diazotrophs) cyanobacteria are considered to contribute the most to marine nitrogen fixation, and thereby fuel the surrounding phytoplankton communities with bioavailable ammonia. LÄS MER
5. Significance of N2 fixing planktonic symbioses for open ocean ecosystems
Sammanfattning : Di-nitrogen (N2) fixers, also called diazotrophs, are able to reduce atmospheric N2 into bioavailable nitrogen, giving them an advantage in open ocean regions with low dissolved inorganic nitrogen concentrations. The focus of this thesis are three lineages of symbiotic heterocystous filamentous types (het-1, het-2 and het-3), that associate with several genera of microalgae called diatoms (collectively referred to as Diatom Diazotroph Associations, DDAs).
