The Ecological Society of America currently stands at a boundary between 100 successful years for the Society and an uncharted future for the planet. The Centennial meeting will support both retrospective and prospective sessions – looking back at the history of the field of ecology as well as forward into its future. Proposals examining historical topics and the history of ecology, as well as proposals from early career scientists and students that shine a light on the future of ecological science are welcome. Proposals that explore interdisciplinary connections with areas of social and natural science outside of ecology or that relate to ecological education at any level are also encouraged.
