Here we use the nonparametric statistic, Kendall's tau, to assess trends in biomass of exploited marine species across a range of ecosystems.The proportion of ‘Non-Declining Exploited Species’ (NDES) is compared among ecosystems and to three community-level indicators that provide a gauge of the ability of a marine ecosystem to function both in provisioning and as a regulating service: survey-based mean trophic level, proportion of predatory fish, and mean life span.In some ecosystems, NDES corresponds to states and temporal trajectories of the community indicators, indicating deteriorating conditions in both the exploited community and in the overall community.However differences illustrate the necessity of using multiple ecological indicators to reflect the state of the ecosystem.For each ecosystem,wed iscuss patterns in NDES with respect to the community-level indicators and present results in the context of ecosystem-specific drivers.We conclude that using NDES requires context-specific supporting information in order to provide guidance within a management framework.
