    Summary: 1. Ecosystems are complex and multivariate; hence, methods to assess the dynamics ofecosystems should have the capacity to evaluate multiple indica tors simultaneously. 2. Most research on identifying leading indicators of regime shifts has focused on univariatemethods and simple models which have limited utility when evaluating real ecosystems, par-ticularly because drivers are often unknown. 3. We discuss some common univariate and multivariate approaches for detecting criticaltransitions in ecosystems and demonstrate their capabilities via case studies. 4. Synthesis and applications. We illustrate the utility of an information theory-based indexfor assessing ecosystem dynamics. Trends in this index also provide a sentinel of both abruptand gradual transitions in ecosystems.
