Genomic Mapping of Speciation-Related Traits in Hybridizing Sculpins (Cottus)

European freshwater sculpins, Cottus rhenanus and Cottus perifretum, have formed hybrid lineages (invasive Cottus) in the Lower River Rhine. The hybrid Cottus particularly resembles one of its ancestral species, C. perifretum, in phenotypic features. This contrasts with the fact that the invasive genome...

Environmental and Genetic Determinants of Bacterial Microbiota and Parasites...

Natural hybrid zones often emerge at habitat clines where distinct populations meet, mate and hybridize. The possible factors that govern the dynamics of a hybrid zone are insufficiently explored. For example symbiotic bacteria and also parasites can induce selection pressure by influencing the host’s...
