Title of the thesis
Genomic divergence and speciation in lampreys
Current Research Topics
The thesis research will investigate the genomic basis of species divergence using lampreys as model system. Two paired species found in Europe are used: Lampetra fluviatilis (LF) and Lampetra planeri (LP). Despite distinct life histories, both species use the same breeding habitats and may represent two ecotypes of a single species.
The objectives of the thesis are to:
- Identify the genomic regions linked to the divergence between both species using available genomic data
- Measure the level of hybridization in wild LF and LP populations and the frequency of different hybrids types using SNPs genotyping. Controlled crosses with hybrids and individuals from both parental species will be performed to measure the viability of different hybrid types.
- Investigate the role of immune system genes in reproductive isolation. Controlled crosses will also be performed to test the effect of genes of the immune system on pre-zygotic reproductive isolation. This part of the project will be conducted in close collaboration with the laboratory of Thomas Boehm in Freiburg.
