Population Ecology, formerly known as Researches on Population Ecology launched in Dec 1952, is the official journal of the Society of Population Ecology. Population Ecology publishes original research articles and reviews (including invited reviews) on various aspects of population ecology, from the individual to the community level. Among the specific fields included are population dynamics and distribution, evolutionary ecology, ecological genetics, theoretical models, conservation biology, agroecosystem studies, and bioresource management. Manuscripts should contain new results of empirical and/or theoretical investigations concerning facts, patterns, processes, mechanisms or concepts of population ecology; those purely descriptive in nature are not suitable for this journal. All manuscripts are reviewed anonymously by two or more referees, and the final editorial decision is made by the Chief Editor or an Associate Editor based on the referees' evaluations.
