Foraminifera could be used as indicators to evaluate the impacts of oil spills because the crude oil causes several disturbances on the development and reproduction of the species. However, little is known about the relationship between mangrove species and this pollutant. Foraminiferal assemblages were studied in 22 surface sediment samples collected from a mangrove in Guanabara Bay (Brazil) that was severely impacted by an oil spill six years earlier.

Article Synopsis
  • The study examines the environmental degradation of Sepetiba Bay, Brazil, focusing on the impact of toxic elements on living benthic foraminifera.
  • It utilizes a multiproxy approach, correlating benthic foraminiferal species density with pollutants like arsenic and lead, revealing a poor ecological quality status, especially in inner bay areas.
  • The findings suggest that specific tolerant foraminifera species can indicate environmental health, making the study significant for coastal ecosystem management and biomonitoring efforts.

This study aimed to describe for the first time the vertical motion behaviour of the intertidal foraminifera and its contribution to bioturbation. Its infaunal behaviour leads to the creation of a one-end tube within the first centimetre of sediment. In addition, a vertical trail following behaviour was described for the first time in foraminifera, which may be linked to the sustainability of the biogenic sedimentary structures.

Article Synopsis
  • Plastic pollution is a major environmental issue in the Anthropocene, causing visual and physical harm along with releasing harmful chemicals.
  • Despite the importance of benthic foraminifera in ecosystems, only a tiny fraction (0.4%) of studies have looked into the effects of micro- and nano-plastics on them.
  • The authors recommend including benthic foraminifera in future plastic pollution research to better understand their responses and to use them as indicators of pollution levels for effective coastal ecosystem management.

Using benthic foraminifera, we evaluate the ecological quality status (EcoQS) of transitional waters of the Guanabara Bay (SE Brazil) by applying the diversity-based index exp (H') and the sensitivity-based Foram-AMBI for the first time in South America. The Guanabara Bay was selected for this study as it is one of the largest transitional ecosystems in the State of Rio de Janeiro and has been severely impacted by anthropogenic activities. Concentrations of potentially toxic elements (PTEs) were assessed by sequential chemical extraction in three phases (i.
