Center for Tropical Research Spring 2009 Newsletter
CTR Researchers report from Peru, Brazil, and Colombia.
The Center for Tropical Research (CTR) has posted its Spring 2009 newsletter on the News and Updates page of its website. The biannual CTR newsletter contains feature articles by CTR researchers, field reports from graduate students, a letter from CTR Director Thomas Smith, and updates on CTR projects, field research trips, graduate student and postdoctoral scholar activities, and donor and grant support.
The April 2009 feature article by Zachary Cheviron describes his studies of adaptation to high elevation in Rufous-collared Sparrows in habitats in the Peruvian Andes that are threatened by climate change. The two field reports are from CTR graduate students doing work in Brazil and Colombia. 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 in Colombia, how past climatic fluctuations have affected bird populations, and the future impacts of climate change.
