Welcome!
The unifying goal of the senior scientists, postdoctoral researchers, and graduate students at the Center for Tropical Research (CTR) is to understand the biotic processes that underlie and maintain the diversity of life in the tropics and to advance conservation efforts that protect endangered species and habitats.
| Zachary Cheviron examines adaptation to high elevation in Rufous-collared Sparrows in the Peruvian Andes. Hilton Oyamaguchi reports on his studies of adaptive variation in two frog populations in the Amazon rainforest of Brazil. Raul Sedano discusses the mechanisms of population differentiation in Andean birds and how climatic fluctuations affect bird populations. See our News & Updates section. |

CTR Avian Influenza Virus Research and Surveillance Projects in North, Central, and South America, Cameroon, and Vietnam In 2006, CTR was awarded a four-year grant from the National Institutes of Health/National Institute of Allergy and Infectious Diseases entitled “Effects of Avian Migration and Anthropogenic Change on the Distribution and Transmission Risks of Avian Influenza.” CTR researchers are working in the field and the laboratory to determine the role that North American migratory passerines play in the dispersion of avian influenza virus (AIV) strains. Collaborators have collected more than 36,000 cloacal and tracheal bird samples to screen for AIV. CTR researchers are also monitoring wild and domestic birds for AIV in Cameroon and Vietnam.
