Short summary
Short summary
The foraminifer Trochammina hadai, native to Asia, has been found in the USA, Canada, Sweden, France, Brazil, and Australia coastal waters. The primary vectors of introduction include mariculture of oysters and the plant matter in which they were shipped, as well as the release of ballast water/sediment in receiving ports. Secondary introductions occur by mud attached to anchors of fishing and pleasure boats. Globally, the species has spread rapidly, impacting native species and local biodiversity.

Short summary
This study evaluates benthic foraminifera as indicators of environmental health in Brazil’s coastal waters and tests Foram-AMBI using a regional species list and criteria for ecological quality status (EcoQS). A total of 95 species were classified into five groups based on their response to total organic carbon. Data from Sepetiba Bay and Guanabara Bay validated these groups, showing that Foram-AMBI accurately reflects ecological conditions. The study highlights the importance of regional species lists for biomonitoring.

Short summary
The Espírito Santo Continental Shelf hosts a highly diverse benthic foraminiferal fauna, with assemblages varying across distinct compartments due to differences in sediment composition, seafloor morphology, and oceanographic conditions, reflecting its mixed carbonate–siliciclastic nature.
The Espírito Santo Continental Shelf hosts a highly diverse benthic foraminiferal fauna, with...
