16. Fishing for Females : Sensory Exploitation in the Swordtail Characin
Abstract : Mate choice plays an important role in sexual selection and speciation. The evolution of mate choice is intriguing in cases where choosy individuals gain little except for genetic material from the mate and where the trait used as a criterion for the choice is costly to its bearer.

17. Condition-dependence in life history evolution
Abstract : Ageing is the progressive physiological deterioration that appears with increasing age and eventually leads to a decline in survival and reproduction. This physiological process is omnipresent across the tree of life, but the expected trajectory can widely vary between and within species. READ MORE

18. Sex in Murky Waters : Anthropogenic Disturbance of Sexual Selection in Pipefish
Abstract : Animals experience variation in their environment because of natural changes. However, due to anthropogenic disturbance, the speed and severity of these changes have recently increased. This thesis investigates how reproductive behaviours may be affected by human induced environmental change. READ MORE

19. 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.

20. The role of Assortative Mating in the Initial Stages of Sympatric and Parapatric Speciation
Abstract : Divergence in the face of gene flow is perhaps the most wildly disputed subject among researchers through time. The debate is an old one and we find its origin as far back as the era of Darwin. READ MORE
