Abstract
Frontiers in Marine Science launched the Marine EcosystemsEcology (FMARS-MEE) section in2014, with a paper that identified eight grand challenges for the discipline (Borja, 2014). Sincethen, this section has published a total of 370 papers, including 336 addressing aspects of thosechallenges. As editors of the journal, with a wide range of marine ecology expertise, we felt it wastimely to evaluate research advances related to those challenges; and to update the scope of thesection to reflect the grand challenges we envision for the next 10 years. This output will matchwith the United Nations (UN) Decade on Oceans Science for Sustainable Development (DOSSD;Claudet et al., 2020), UN Decade of Ecosystems Restoration (DER;Young and Schwartz, 2019), andthe UN Sustainable Development Goals (SDGs;Visbeck et al., 2014)
