Harvey, Yvonne deReynier, Dawn Davis, Stephani G. Zador, Sarah Gaichas, Mariska Weijerman, Elliott L. Hazen, Isaac C. Kaplan --- class: top, left ## [This paper](https://www.frontiersin.org/articles/10.3389/fmars.2019.00641/full) reviews example cases where scientists have had success in using ecosystem analysis and modeling to inform management priorities and stakeholder activities, and identifies practices that help bring new ecosystem science information into existing policy processes. <img src="EDAB_images/HowardsPaper.png" width="80%" style="display: block; margin: auto;" /> .footnote[ Townsend, H., Harvey, C.
