Long-term studies have provided critical insights into our understanding of the controls over the structure and function of ecological systems. These studies have often reversed conclusions based on short-term studies, elucidated previously unknown ecological interactions, and allowed for an understanding of lag effects, context-dependence, and longer-term ecological and evolutionary processes. They have revealed the impacts of human modifications of the environment, led to improved management under variable conditions, and are critical for predicting and managing future environmental changes. In celebration of ESA’s Centennial, this organized oral session will highlight the contributions of long-term research to ecological science, management, and policy. It will also highlight how addressing the most pressing environmental issues, now and in the future, relies on the scientific infrastructure that supports research on long-term ecological trends (e.g. field stations, historical collections, long-term monitoring, databases).
