Opportunities and challenges in incorporating benthic foraminifera in marine and coastal environmental biomonitoring of soft sediments: from science to regulation and practice

Scientific studies have demonstrated the usefulness of benthic foraminifera as bioindicators to assess the health of marine, coastal, and transitional ecosystems. Similar to macrofauna, these organisms are reliable proxies for biomonitoring. Despite recent scientific advances, Brazilian official monitoring plans using biotic indices on coastal and ocean environments with soft sediment areas remain mostly restricted to a few types of organisms. Therefore, to include benthic foraminifera in Brazilian biomonitoring routines regulated by national environmental guidelines and standards, the paper presents the challenges, which must be overcome, some recommendations and steps to move forward to implement foraminifera as bioindicators in biomonitoring routines. In light of it, it is essential to consider the contribution of the Brazilian foraminiferal research in this implementation process, improving ecological quality indices, adapting methods, and applying genetics tools. This paper is a step in this direction, which aims to strengthen the role of benthic foraminifera as a reliable tool in Brazilian biomonitoring.
