My research focuses on the structure and organization of bird communities, primarily in tropical forests. I am particularly interested in the impact of resource abundance (e.g., fruit) on temporal and spatial variation in bird populations, spatial patterns of diversity, and effects of habitat alterations on bird populations. The current focus of tropical work is in Ecuador, at the Tiputini Biodiversity Station (~0o 38' S, 76o 08' W), where we have several ongoing projects. One project focuses on spatial and temporal patterns of bird diversity (as well as aspects of community composition, population dynamics, and movement) within and between two 100-ha study plots. The Station was established in 1994 by the Universidad San Francisco de Quito on a tract of undisturbed forest within the ha Yasuní Biosphere Reserve. We established the two 100-ha plots in terra firme forest in February 2001. (A protocol has been established for use of these plots for other researchers.) We use a combination of mist nets and direct observations to record the occurrence and locations of birds within the two plots. A second major project focuses on reproductive success in manakins (Pipridae). A third project, carried out in collaboration with many people at the station, is a camera-trapping program focused on large terrestrial mammals (see article in El Comercio). We have camera traps established along trails, on the plots, and at saltlicks (saladeros). Students in my lab have come from a variety of countries (e.g. Argentina, Bolivia, Brazil, Chile, Colombia, Guatemale, Luxembourg, Peru, Uruguay, United States, Venezuela).
Courses taught at UM-St. Louis include Ornithology, Wildlife Conservation and Ecology, Tropical Ecology and Conservation, and Biometry. In addition, I teach courses on avian ecology and multivariate analyese through Laboratorio de Investigaciones Ecológicas de las Yungas, Universidad Nacional de Tucumán, Argentina. Avian ecology courses are co-taught with Piter Blendinger, LIEY and CONICET. The course, Ecología y Conservación de Aves en el Cono Sur, is a two-week field-based course that visits several sites in northwestern Argentina. We typically have fifteen students from countries throughout South America.
