Oikos is a journal issued by the Nordic Ecological Society and is one of the leading peer-reviewed journals in ecology. Oikos publishes original and innovative research on all aspects of ecology. Emphasis is on theoretical and empirical work aimed at generalization and synthesis across taxa, systems and ecological disciplines. Papers should be well founded in ecological theory and contribute to new developments in ecology by reporting novel theory or critical experimental results. Confirming or extending the established literature is given less priority. Synthesis of new and emerging fields in ecology and beyond is encouraged. Papers of review character should should strive for conceptual unification and being a point of departure for future work rather that restrospective summaries of established fields or topics. Papers in Brevia, Horizons and Forum sections are given high priority in the publication process.
