With the intention of communicating scientific knowledge to the public and stakeholders, focus is on evaluating and comparing the status of exploited marine ecosystems using a set of six ecological indicators and a simple and transparent graphic representation of ecosystem state (pie charts). A question that arose was whether it was acceptable to compare different types of marine ecosystems using a generic set of indicators. To this end, an attempt is made to provide reference levels to which ecosystems can be objectively compared. Unacceptable thresholds for each indicator are determined based on ecological expertise derived from a questionnaire distributed to a group of scientific experts. Analysis of the questionnaires revealed no significant difference in the thresholds provided for different ecosystem types, suggesting that it was reasonable to compare states directly across different types of ecosystem using the set of indicators selected. specialized comparative approach indicators marine ecosystems reference levels thresholds 036 020 67 4 717-731 2010 1054-3139 https://www.documentation.ird.fr/hor/fdi:010049489 10.1093/icesjms/fsp287 1054-3139 [F B010049489] https://www.documentation.ird.fr/hor/fdi:010049489 https://www.documentation.ird.fr/intranet/publi/2010/05/010049489.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2010-06-02 2017-08-23 fdi:010049489 fre
