Substance abuse disproportionately impacts American Indian/Alaska Native (AI/AN) communities in the United States. For the increasing numbers of AI/AN individuals who enter and receive treatment for their alcohol or other drug problem it is imperative that the service they receive be effective. This study used qualitative methodology to examine attitudes toward evidence-based practices, also known as evidence-based treatments (EBTs) in minority-serving substance abuse treatment programs in the San Francisco Bay area. Twenty-two interviews were conducted in the study, of which seven were with program directors and substance abuse counselors at two urban AI/AN focused sites. These clinics were more likely than other minority-focused programs to have experience with research and knowledge about adapting EBTs. Only in the AI/AN specific sites did an issue arise concerning visibility, that is, undercounting AI/AN people in national and state databases. Similar to other minority-focused programs, these clinics described mistrust, fear of exploitation from the research community, and negative attitudes towards EBTs. The underutilization of EBTs in substance abuse programs is prevalent and detrimental to the health of patients who would benefit from their use. Future research should explore how to use this research involvement and experience with adaptation to increase the adoption of EBTs in AI/AN serving clinics.

Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses the knowledge gap of vertical movements by compiling the first global synthesis of vertical habitat use by elasmobranchs from data obtained by deployment of 989 biotelemetry tags on 38 elasmobranch species. Elasmobranchs displayed high intra- and interspecific variability in vertical movement patterns. Substantial vertical overlap was observed for many epipelagic elasmobranchs, indicating an increased likelihood to display spatial overlap, biologically interact, and share similar risk to anthropogenic threats that vary on a vertical gradient. We highlight the critical next steps toward incorporating vertical movement into global management and monitoring strategies for elasmobranchs, emphasizing the need to address geographic and taxonomic biases in deployments and to concurrently consider both horizontal and vertical movements.
