Biogeography of speciation of two sister species of neotropical amazona (Aves, Psittaciformes) based on mitochondrial sequence data.
Coalescent theory provides powerful models for population genetic inference and is now increasingly important in estimates of divergence times and speciation research.We use molecular data and methods based on coalescent theory to investigate whether genetic evidence supports the hypothesis of A.pretrei and A.tucumana as separate species and whethe
