1. Ecology and Evolution of Adaptive Morphological Variation in Fish Populations
Abstract : The work in this thesis deals with the ecology and evolution of adaptive individual variation. Ecologists have long used niche theory to describe the ecology of a species as a whole, treating conspecific individuals as ecological equivalent. READ MORE

2. Marriage, money and migration
Abstract : The thesis consists of a summary and four self-contained papers.Paper [I] examines the effects of interregional migration on gross earnings in married and cohabiting couples. In particular, we examine the link between education level and income gains. READ MORE

3. The role of regeneration in plant niche differentiation and habitat specialization
Abstract : To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. READ MORE

4. The links between dispersal and individual fitness: correlation or causality? : Exploring mechanisms using correlative and experimental approaches in a passerine bird species, the collared flycatcher
Abstract : Dispersal is commonly defined as the movement of an individual from its natal orprevious breeding site to a new breeding site. Because dispersal involves movements ofindividuals and genes among populations, it is recognized as a key life history trait withstrong effects on many ecological and evolutionary processes such as populationdynamics and genetics but also species spatial distribution or response to brutalenvironmental variations induced by human activities.

5. Solid-state nanopores : fabrication and applications
Abstract : Nanopores are of great interest in study of DNA sequencing, protein profiling and power generation. Among them, solid-state nanopores show obvious advantages over their biological counterparts in terms of high chemical stability and reusability as well as compatibility with the existing CMOS fabrication techniques.
