Impacts of introgressive hybridisation may range from genomic erosion and species collapse to rapid
adaptation and speciation but opportunities to study these dynamics are rare. We investigated the
extent, causes and consequences of a hybrid zone between Anopheles coluzzii and Anopheles gambiae
in Guinea-Bissau, where high hybridisation rates appear to be stable at least since the 1990s. Anopheles
gambiae was genetically partitioned into inland and coastal subpopulations, separated by a central

Discordance between mitochondrial and nuclear patterns of population genetic structure is providing key insights into the eco-evolutionary dynamics between and within species, and their assessment is highly relevant to biodiversity monitoring practices based on DNA barcoding approaches. Here, we investigate the population genetic structure of the fire salamander Salamandra salamandra in peninsular Italy. Both mitochondrial and nuclear markers clearly identified two main population groups.
