Amphibian DNA shows marked genetic structure and tracks Pleistocene climate change in northeastern Brazil. Molecular Phylogenetics and Evolution 38:171-188.Ĭarnaval, A. Coalescent models reveal the relative roles of ancestral polymorphism, vicariance, and dispersal in shaping phylogeographical structure of an African montane forest robin. Avian speciation in the Pantepui: the case of Percnostola " leucostigma" saturata. Avian Mitochondrial DNA sequence divergence across as headwater stream of the Rio Tapajos, a major Amazonian river.

Studies on Neotropical Fauna and the Environment 38:87-94.īates, J. An initial assessment of genetic diversity in ten bird species of South American Cerrado. Journal of Raptor Biology 36:183-187.īates, J. Morphology, genetics and the value of voucher specimens: an example with Cathartes vultures. Biogeographic patterns in the South American Cerrado: a tropical savanna hotspot.

These large collaborative projects are providing new perspectives on the history of Amazonia. Our current NSF Dimensions of Diversity grant on the assembly of the Amazonian biota and our NSF grant to survey birds and their parasites across the southern Amazon are generating genomic data for analysis in collaboration with paleoecologists, climatologists, geologists, and remote sensing experts from the U.S.

We are working up similar data sets for Malawian birds. Josh Engel and I are working up multi-species phylogeographic studies of birds across the Albertine Rift, based the Bird Division's long term research throughout the region. Chicago) is studying the diversification of birds in Afromonte forests Jacob Cooper (Committee on Evolutionary Biology, U. Illinois, Chicago) is also working Boris Igic and me, after doing her Master Degree in her native Colombia on genomics and the evolution of migrating Fork-tailed Flycatchers ( Tyrannus savana). New graduate student Valentina Gomez Bahamon (U. Chicago) is studying the impact of urbanization on Neotropical birds. Illinois, Chicago, co-advised with Mary Ashley) is studying phlylogeography of Amazonian white sand specialist birds and Natalia Piland (Committee on Evolutionary Biology, U. We seek to create a broader understanding of diversification in the tropics from a comparative biogeographic framework (Silva and Bates 2002, Kahindo et al, 2007, Bates et al. Illinois, Chicago with Roberta Mason-Gamer, is studying specialization in birds from a modern phylogenetic perspective. Shane DuBay is doing his dissertation research in the Himalayas on physiological plasticity in Tarsiger Bush Robins. 2015) and Amazonian birds (through our NSF Dimensions of Diversity grant). 2013), and we are entering into the genomic realm focusing initially on Andean (Winger et al. Weyandt dissertation research) and South America, particularly the Amazon (Savit dissertation research, Savit and Bates 2015, Figueiredo et al. 2014), the Eastern Arc Mountains (Lawson dissertation research, Lawson et al. We also have used genetic data to better understand evolutionary patterns in relation to climate change across landscapes (e.g., Carnaval and Bates 2007) that include the Albertine Rift (through our MacArthur Grants, e.g., Voelker et al. 2015, Winger and Bates 2015, Lawson et al. Caballero dissertation research, Block et al. Phylogeographic work has sought to understand comparative patterns of divergence at level of population and species across different biomes (Bates et al 2003, Bates et al. Phylogenetic work on Neotropical birds has focused on rates of diversification and comparative biogeography (Tello and Bates 2007, Pantané et al 2009, Patel et al. Research in the our lab has involved gathering and interpreting genetic data in both phylogeographic and phylogenetic frameworks. I am an ornithologist, but students working with me and my wife Shannon Hackett and other museum curators also have studied amphibians and small mammals (bats and rodents) and more recently internal, external and blood parasites (e.g., Lutz et al. We study comparative genetic structure and evolution primarily in the Afrotropics, the Neotropics, and the Asian tropics. My students and I study genetic structure in tropical birds and other organisms to address how this diversity evolved and how it continues to evolve as climates change and humans continue to alter landscapes. I am most intrigued by evolution at the tips of the tree of life. tropics harbor the highest species diversity on the planet.
