The tropics harbor the highest species diversity on the planet. 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.

Systematics, genetic structure, and geographic variation in the tropics.
My research focuses on genetic structure of tropical birds, primarily at the level of populations and species. At a continental scale, I use data from DNA sequences to uncover patterns of history among lineages of South American, African, and Malagasy birds. Multi-taxon studies, in which samples of different taxa are obtained at each geographic site provide insightful comparative data sets. Coupled with an understanding of distribution and ecology, we can search for correlations between molecular differentiation and other aspects of the biology of these birds such as morphological differentiation, ecology (e.g., habitat selection, foraging guild membership, breeding system, degree of seasonal movement) and phylogenetic relationships (phylogenetic constraints). With Shannon Hackett and TFM research scientist Jason Weckstein, I have been studying co-evolutionary patterns in birds, their parasites and pathogens. In addition to addressing evolutionary questions, I have focused research efforts on demonstating how patterns of genetic structure have relevance to conservation biology.
My former students have studied similar questions in birds and other organisms throughout the tropics (e.g., flycatchers and antbirds in the neotropical lowlands, Jose Tello; Albertine Rift warblers, Charles Kahindo; Ana Carnaval, frogs of northeastern Brazil; Philippine Fruit bats, Trina Roberts; East African frogs, Lucinda Lawson; Philippine insectivorous bats, Sara Weyandt.). Current students Ben Winger and Aaron Savit (University of Chicago) are studying evolution of South American birds, and Isabel Caballero (Univeristy of Illinois, Chicago) is studying population genetics of Peregrine Falcons.
At the local geographic scale, I have studied genetic structure in populations of five forest understory species from continuous forest and from forest fragments in northeastern Bolivia. The sites in continuous forest and the forest fragments are all within 200 km of one another, yet genetic differentiation appears to have developed in the forest fragments for three of the species studied. This work also has implications for the design of nature reserves and for conservation planning, because my data indicate that genetic structure in these forest species can be affected by forest fragmentation.
I also study geographic variation using traditional museum specimens and computerized databases. One such study of geographic variation in some South American finches (genus Tiaris) uncovered misconceptions about traditional species limits and diagnosable populations. Another led to the description of a new species of hanging parrot (Loriculus camiguinensis), which is endemic to the small island of Camiguin in the Philippines. This description was based on a series of specimens collected in the 1960s and deposited in the Field Museum's collections. A colalborative project with Research Associate Guy Kirwan used Field Museum specimens to document a previously unrecognized pattern of migration in Eurpoean stonechats (Saxicola torquata). In 2010, a collaborative project led by Research Associate Gary Voelker described a new species of Bush-shrike, Laniarius willardi, based on a detailed anaylsis of both modern and historical Field Museum specimens. The new species, named in honor of our recently retired Collections Manager of Birds David Willard, is only known from mid-elevations of Albertine Rift forests in central Africa and appears highly endangered based on our ongoing assessments of the niche of this species.
Such studies demonstrate the vital importance of museum collections and, along with results of molecular studies, emphasize that additional inventory work on birds is sorely needed. Collaborative fieldwork by the division over the last 10 years has included Malawi, the Democratic Republic of Congo, South Africa, Uganda, Central African Republic, Gabon, Peru, Brazil, Bolivia, Madagascar and Bhutan. In all countries where we work, building capacity for collections-based ornithological science is a primary goal of our efforts because collections everywhere can be used for teaching and research, telling us now and in the future so much about the birds with which we share the planet.
