Eastern Yellow Robin Mitonuclear Evolution data collection

This Data Collection presents data for research on characterization of the evolution of novel, extended sex chromosomes and their role in population divergence and climate adaptation in an Australian Eastern Yellow Robin. The species falls into two lineages bearing distinct mitochondrial genomes and nuclear-encoded mitochondrial genes on the sex chromosomes. The research aims to test whether this extraordinary genome arrangement is splitting the species into two forms: one adapted to hotter and drier environments, one to milder ones.
