Intraspecific genomic variation and local adaptation in a young hybrid species, the Italian sparrow (Passer italiae)
In this study we investigate how the homoploid hybrid Italian sparrow (Passer italiae, a homoploid hybrid species resulting from past hybridization between the house sparrow (Passer domesticus) and the Spanish sparrow (Passer hispaniolensis)) has evolved since its formation. We focus on population divergence and the role of climatic variation on genomic divergence. As well as how constraints and novel genetic variation, linked to admixture, have impacted the hybrid genomic evolvability, limiting or favouring its adaptive potential and ultimately its population divergence.
