An international journal of ecology

ÉCOSCIENCE is published quarterly by the University Laval. ÉCOSCIENCE is a multidisciplinary journal that stems from the need to create a forum for all ecologists. ÉCOSCIENCE publishes original work focusing on patterns and processes at various temporal and spatial scales and at different levels of biological organization.

ÉCOSCIENCE welcomes work in evolutionary and behavioral ecology, ecophysiology, population and community ecology, landscape and ecosystem ecology, numerical ecology, dendroecology and, paleoecology.
