Abstract/Summary Managing local water quality in coastal marine ecosystems is fundamental for the long-term protection of diversity and carbonate production, to maintain reef accretion. Although there are numerous indicators to measure the resilience and health of reef environments, the use of foraminifera is building momentum. Key mechanisms controlling productivity in benthic ecosystems can be assessed by investigating foraminiferal calcification and physiology in response to changing water quality (primarily nutrients) and temperature. Benthic foraminifera are among the most abundant protists in the shallow reef marine environment yet, even in low abundance, the ecological record they leave in the sediments is extremely useful for reconstructing past and present environmental conditions. This application can enable studies to pinpoint the duration and timing of long-term influence of eutrophication in coastal marine ecosystems. This is largely due to their biology and sensitivity to environmental conditions, high taxonomic diversity (ca. 4,000 extant species) and relatively short life cycles (months to a year or more). However, altering ecological conditions influence species differently, so the community and physiological responses needs to be clearly identified. For example, the host-algae association is complex and typically photosymbiont-bearing marine organisms suffer adverse metabolic effects directly from sediment runoff, inorganic nutrient runoff, light and temperature. Therefore, validation is recommended when applying indices created in one region to another.
