Research Interests
My major area of interest is conservation biology, including aspects of ecological monitoring, population ecology and species extinctions. I consider it of paramount importance, in endangered species research, to determine and distinguish the effects of natural and anthropogenic factors on population fluctuations and extinctions. Therefore, I participate and/or promote research on the ecology and conservation of birds with small populations; effects of climate, particularly of El Niño events; movements and dispersal; effects of parasites and diseases; long-term research and ecological monitoring of the Harpy Eagle, Galapagos Hawk, Galapagos Penguin, Galapagos Flamingoes, Flightless Cormorant and Mangrove Finch; and last, but not least, impacts of training local people on conservation.
Conservation goals cannot have a lasting impact without involvement of qualified local professionals. Therefore, I am particularly interested in the training of students and enhancement of local capacities for long term research, wildlife management and conservation. Some of my high school students have already graduated as Biologists from Ecuadorian universities (e.g., Martha Veliz and Mariana Jaramillo).
Several undergraduate students who received hands-on training in previous research projects are now having significant impact on conservation action: Diógenes Aguirre, Juan Carlos Valarezo, Carolina Larrea, Gustavo Jiménez, Paola Buitrón, Susana Cárdenas, Paolo Piedrahita, Richard Vokes, Timo Koester, Carlos Fonseca, Carlos Carrión, Carlos Vinueza, Xavier Arturo López, Robert Baulfour, and Daniel Valdivieso.
As senior scientist of the Neotropical Science and Student Education program of the Peregrine Fund, I am currently co-supervising thesis research projects of the following students: Maximiliano Galmes (PhD, Argentina), Victor Escobar (PhD, Chile), Renzo Piana (PhD, Peru), Francisco Denes (PhD, Brazil) Marcus Canuto (MSc, Brazil), Jose de Jesus Vargas-Gonzales (MSc, Panama), Mari Cruz Jaramillo (MSc, Ecuador), Jose Luis Rivera (MSc, Ecuador), Edwin Campbell (MSc, Panama), Laura Riba-Hernandez (MSc, Costa Rica) Andrea Calispa (BSc, Ecuador), Saskia Santamaria (BSc, Panama), Sandra Quiroga (BSc, Colombia), Henry Delgado (BSc, Colombia). All of these students conduct thesis research on little known or endangered species of raptors.
