5. Lampreys as a model of speciation research
6. Goals of the Thesis
Chapter 2: Investigating gene flow and reproductive isolation in lampreys 
Article 1: Low reproductive isolation and highly variable levels of gene flow reveal limited progress towards speciation between European river and brook lampreys
Chapter 3: Investigating divergence history of European river and brook lamprey 
Article 2: Reconstructing the demographic history of divergence between European river and brook lampreys using Approximate Bayesian Computations
Chapter 4: Understanding speciation: moving toward genomics 
Article 3: Inferring the demographic history underlying parallel genomic divergence among pairs of parasitic and non-parasitic lamprey ecotypes
Chapter 5: Effect of anthropogenic disturbance on population genetic diversity and structure of European brook lamprey 
Article 4 Moderate effect of river fragmentation but strong influence of gene flow between ecotypes on the genetic diversity of brook lamprey populations
Chapter 6: Discussion & Perspectives 
1. Low levels of reproductive isolation and high viability of F1s at an early developmental stage
2. The importance of the geographical context in studying speciation
3. The complexity of histories of divergence
4. Better characterizing isolated L. planeri populations
