We are interested in understanding how island species adapt to local conditions upon colonization from the mainland (or from other islands) and the ecological and genomic mechanisms involved in the…

We use molecular genetic tools and patterns of phenotypic variation to reconstruct the evolutionary history of the songbird genus Junco in order to understand the factors, mechanisms and timing of…

Remote oceanic islands provide unique scenarios in which to study the factors involved in population divergence and the formation of new species. The Reunion gray white-eye (Zosterops borbonicus) shows a…

For more than a decade now we have been investigating the evolutionary history of the yellow-rumped warbler Setophaga coronata (formerly Dendroica coronata). The complex is composed of a white-throated form,…

The island of New Guinea includes some of the least explored areas of the planet. We collaborate with Christophe Thébaud at the University of Toulouse, France, and Hidayat Ashari at…

  Since 2010, we have been studying the evolution and ecology of the fascinating endemic avifauna of Guadalupe, a volcanic oceanic island off the coast of Baja California, in Mexico.…

  We are interested in how populations evolve into distinct evolutionary lineages, and the relative roles of geographic isolation, natural selection and sexual selection in this process. Mexico and Central…

We are interested in the evolutionary mechanisms that drive speciation in tropical regions, and we investigate the relative roles of geography and selection in driving lineage divergence. In Ecuador we…

  In collaboration with Juan Carlos Alonso at the MNCN, we are conducting detailed surveys of genetic diversity in Iberian populations of the great bustard (Otis tarda). Using mtDNA and…
