About the Lab

 

The Behavioral Ecology and Ornithology Lab (LECO) at the Universidade Federal do Paraná is dedicated to advancing research in animal behavior, with a strong emphasis on avian ecology, evolution, and conservation. Our work integrates behavioral ecology, sexual selection, host-parasite interactions, bioacoustics, and migration ecology to explore how environmental factors—both biotic (e.g., species interactions, parasitism) and abiotic (e.g., climate, urbanization)—shape animal phenotypes and adaptive strategies.​

​

Our lab combines field observations, experimental studies, and multidisciplinary approaches (e.g. molecular analyses, citizen science) to address both proximate mechanisms and ultimate causes (e.g., fitness consequences, evolutionary trade-offs) of behavior. By mentoring students and collaborating globally, we aim to deepen understanding of avian biodiversity while contributing to conservation in threatened biomes like the Atlantic Forest.

 

Research​

​

Behavioral Ecology & Sexual Selection

We investigate the evolutionary mechanisms behind avian reproductive behaviors, including courtship displays, mate choice, parental care, and lekking systems. A key focus is the role of sexual selection in shaping secondary sexual traits (e.g., plumage, vocalizations, and courtship displays) in Neotropical birds, such as manakins (Pipridae).

Host-Parasite Interactions

We study how symbiotic organisms (e.g., feather mites, haemosporidians) influence bird health, ornamentation, and fitness.

Avian Migration & Movement Ecology

Using citizen science data, geolocators, stable isotopes, and bioacoustics, we seek to unravel the patterns and drivers of continental bird migration in South America, addressing gaps in tropical migration theory and its conservation implications.

Urban Ecology & Conservation

We assess how anthropogenic changes (e.g., noise pollution, habitat fragmentation) affect avian behavior, communication, and population dynamics, bridging fundamental science with applied conservation.
