A multi-taxonomic framework for assessing relative petrochemical vulnerability of marine biodiversity in the Gulf of Mexico

A fundamental understanding of the impact petrochemicals and other stressors on marine biodiversity is critical for effective management, restoration, recovery, mitigation initiatives. As species-specific information levels petrochemical exposure toxicological response are lacking majority species, a trait-based assessment to rank species vulnerabilities activities in Gulf Mexico can provide more comprehensive means prioritize habitats, ecosystems improved restoration recovery. To initiate standardize this process, we developed framework, applicable wide range vertebrate invertebrate that be used relative population Mexico. Through expert consultation, 18 traits related likelihood exposure, individual sensitivity, resilience were identified defined. The resulting multi-taxonomic vulnerability framework adapted applied variety groups geographic regions. Additional recommendations guidance application under specific scenarios, management needs or data limitations also discussed.
