Short summary
We report the first benthic foraminifera with a composite test (i.e. shell) made of opal, which coats the inner part of the calcitic layer. Using comprehensive techniques, we describe the morphology and the composition of this novel opal layer and provide evidence that the opal is precipitated by the foraminifera itself. We explore the potential precipitation process and function(s) of this composite test and further discuss the possible implications for palaeoceanographic reconstructions.

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.

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.

Short summary
Benthic foraminifera are single-cell marine organisms which can move in the sediment column. They were previously reported to horizontally and vertically transport sediment particles, yet the impact of their motion on the dissolved fluxes remains unknown. Using microprofiling, we show here that foraminiferal burrow formation increases the oxygen penetration depth in the sediment, leading to a change in the structure of the prokaryotic community.

Short summary
Coastal seas experience sediment discharges whose intensity and frequency can strongly be affected by human activities and climate change. We analysed the response of benthic species in an experimental set-up. After the burial under a single thick layer of sediment or multiple thin layers at different times, the analysed species migrate rapidly towards the surface. A stronger effect of a single thick deposit on standing stocks and biodiversity is visible compared to frequent low-sediment inputs.

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.

Short summary
Short summary
Marine microorganisms such as foraminifera are able to live temporarily without oxygen in sediments. In a Swedish fjord subjected to seasonal oxygen scarcity, a change in fauna linked to the decrease in oxygen and the increase in an invasive species was shown. The invasive species respire nitrate until 100 % of the nitrate porewater in the sediment and could be a major contributor to nitrogen balance in oxic coastal ecosystems. But prolonged hypoxia creates unfavorable conditions to survive.

Short summary
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.
