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.

Foraminifera are microorganisms which, due to their abundance and diversity, are often used as proxies to describe climatic changes in marine environments. For this purpose, experiments containing antibiotics that are intended to reduce the activity of other microorganisms are carried out with foraminifera. In our study, we examined the influence of antibiotics on foraminifera and tested whether these chemicals are really harmless for foraminifera or not.

Short summary
Benthic organisms show aggregated distributions due to the spatial heterogeneity of niches or food. We analysed the distribution of Globobulimina turgida in the Gullmar Fjord, Sweden, with a data–model approach. The population densities did not show any underlying spatial structure but a random log-normal distribution. A temporal data series from the same site depicted two cohorts of samples with high or low densities, which represent hypoxic or well-ventilated conditions in the fjord.

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.

This study is the first to show non-selective deposit feeding in the foraminifera Nonionella labradorica and the possible uptake of methanotrophic bacteria. We carried out a feeding experiment with a marine methanotroph to examine the ultrastructure of the cell and degradation vacuoles using transmission electron microscopy (TEM). The results revealed three putative methanotrophs at the outside of the cell/test, which could be taken up via non-targeted grazing in seeps or our experiment.

Short summary
The concentration of the trace metal barium (Ba) in coastal seawater is a function of continental input, such as riverine discharge. Our geochemical records of the severely hot and dry year 2018, and following wet year 2019, reveal that prolonged drought imprints with exceptionally low Ba concentrations in benthic foraminiferal calcium carbonates of coastal sediments. This highlights the potential of benthic Ba / Ca to trace past climate extremes and variability in coastal marine records.

The study presents (1) a validation of a method which was previously published allowing us to recognize different Ammonia phylotypes (T1, T2 and T6) based only on their morphology and (2) a refined biogeographical distribution presented here supporting the putatively invasive character of phylotype T6. Results suggest that phylotype T6 is currently spreading out and supplanting autochthonous phylotypes T1 and T2 along the coastlines of the British Isles and northern France.

Short summary
Small boat harbours are suggested to cause pollution and alien species introductions. Here we analysed surface sediments in Hinsholmskilen harbour (Sweden) for benthic foraminifera and potentially toxic elements. Molecular and morphological analyses of foraminifera show the presence of two alien species, Trochammina hadai and Ammonia confertitesta, whilst pollution is mostly low for Cd, Co, Ni, and Pb. In contrast, As, Zn, Cu, Hg, and Cr have high levels due to the use of these elements in boat paints.
