Modern coastal environments are considered highly selective and dynamic, not only due to the natural variability
of physical and chemical parameters, but also because of anthropogenic contamination. Our study aims to identify
environmental and/or anthropogenic factors influencing benthic foraminiferal abundances over a period of one year
in the Tramandaí-Armazém Lagoon, southern Brazil. Assemblages were composed exclusively of agglutinated species
assigned to the genera Trochammina, Trochamminita, Ammotium, Haplophragmoides and Miliammina. Total abundances
varied throughout the year, reaching the highest values during the wetter months of March and July, when living and
dead assemblages became dominated by Ammotium salsum. This pattern is likely related to salinity fluctuations due
to changes in freshwater input that, consequently, affected the amount of organic matter (e.g., phytodetritus) brought
into the lagoon by surrounding drainages. To assess the impact of anthropogenic pollution, we evaluated total relative
abundances of deformed tests in the Tramandaí-Armazém Lagoon. Relative abundances of deformed tests were the
highest during the months of January and March, when contaminant (e.g., sewage) discharge was probably increased
due to the seasonal population growth in the region.
