11. Sex, Sperm and Speciation : On sexual selection and fertility in hybridizing flycatchers
Sammanfattning : Sexual reproduction entails complex co-evolution between the sexes, necessary for successful fertilization, ensuring individual and population-level fitness. Interfertility is the main criterion for species definition and understanding speciation requires detailed studies of reproductive barriers. LÄS MER
12. Avian Malaria and Interspecific Interactions in Ficedula Flycatchers
Sammanfattning : Parasitism is a core theme in ecological and evolutionary studies. Despite this, there are still gaps in our knowledge regarding host-parasite interactions in nature. LÄS MER
13. Genomics of population decline
Sammanfattning : With human populations forecasted to grow in the next decades, many mammals face increasing anthropogenic threats. The consequential population declines are a precursor to extinctions, as small populations are not only more sensitive to stochastic events, but reduction in population size is generally also followed by a decrease in genetic diversity, which in turn reduces adaptive potential and fitness of the population.

14. Sexual Conflict and Gene Expression in Drosophila melanogaster
Sammanfattning : Sexual conflict is broadly defined as a conflict between the evolutionary interests of the two sexes. Depending on the genetic architecture of the traits involved, it can occur at the level of male-female interactions or take the form of selection acting to change the mean of a shared trait against the sign of its genetic correlation.

15. Spatial Strategies for Biodiversity Conservation
Sammanfattning : Biodiversity is being lost under alarming rates due to an unsustainable socio-economic trajectory causing global change. Such loss is unequally spread over the Earth, and Southern Asia has been and is projected to continue to be one of the most affected regions. LÄS MER
