1. The evolution of flat periwinkles Littorina fabalis and L. obtusata emhasizing mitochondrial introgression and restricted recombination
Abstract : The evolution of species takes in general very long time and different mechanisms are likely to operate during the various stages of this process. Accordingly speciation should be studied at different levels of species divergence. READ MORE

2. Genome Evolution of Neurospora tetrasperma
Abstract : In this thesis work, I have used a comparative genomics approach to study a fungal model organism, Neurospora tetrasperma. My specific focus has been on genomic introgression, intron evolution, chromosomal structural rearrangements and codon usage. READ MORE

3. Neurospora tetrasperma from Natural Populations : Toward the Population Genomics of a Model Fungus
Abstract : The study of DNA sequence variation is a powerful approach to study genome evolution, and to reconstruct evolutionary histories of species. In this thesis, I have studied genetic variation in the fungus Neurospora tetrasperma and other closely related Neurospora species. I have focused on N. READ MORE

4. Large-scale releases of native species : the mallard as a predictive model system
Abstract : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.

5. Genetic Analysis of Cytosolic PGI in Festuca ovina
Abstract : Festuca ovina, sheep's fescue is a widely distributed perennial outbreeder that belongs to the grass family Poaceae and is very common in the northern temperate zone. The genus Festuca s.l. is partitioned into fine-leaved fescues to which F. READ MORE
