1. Dispersal, inbreeding and fitness in natural populations
Abstract : To evaluate how inbreeding affects the viability of small populations, it is crucial to determine what constitutes a population (i.e., the number of breeders in local patches and the degree of dispersal), and also to estimate the reproductive consequences of philopatry and emigration.

2. Dynamics of inbreeding and genetic rescue in a small population
Abstract : Isolation at small population size can reduce individual fitness and impede population growth caused by inbreeding and genetic drift (i.e. inbreeding depression). Inbreeding depression can however be circumvented by gene flow from unrelated individuals through masking of recessive deleterious alleles and contribute to population persistence (i. READ MORE

3. Evolutionary genetics and consequences of inbreeding in sand lizards (Lacerta agilis)
Abstract : Inbreeding is a well-known phenomenon in evolutionary and conservation biology. In the 19th century, Charles Darwin demonstrated the detrimental effects of inbreeding in plants, followed by over a century of extensive research including various animal and plant taxa. READ MORE

4. The use of museum specimens in conservation genomics
Abstract : In the face of an increasing number of species being threatened by extinction, museum collections can constitute a powerful resource for acquiring genomic data of endangered taxa. By utilising datasets that combine genomes from present-day populations with those from historical timepoints, several questions relevant for conservation can be investigated. READ MORE

5. 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
