Our interests cover a wide array of issues concerning the interaction between humans and wildlife at several levels of organization and scales of time and space. I study interactions between individual behavior, life-history theory and population dynamics. I combine theory with long-term population monitoring data based on marked individuals. I emphasize on comparative and applied analyses of variation in life tables, including patterns of senescence, and physiological and experimental studies of growth, development, and parental care. I also investigate the development of analytical methods for pollutants behavior in the environment and the use of living organism as bioindicators.
