Our study provides guidelines improving the reuse of marine microfossil assemblage data, which are valuable for understanding past ecosystems and environmental change. Based on a survey of 113 researchers, we identified key data attributes required for effective reuse. Analysis of a selection of datasets available online reveals a gap between the attributes scientists consider essential and the data currently available, highlighting the need for clearer data documentation and sharing practices.

Through the first large-scale study of meiobenthic ostracods from the diverse and productive reef ecosystem in the Zanzibar Archipelago, Tanzania, we found that the diversity and composition of ostracod assemblages as controlled by benthic habitats and human impacts were indicative of overall reef health, and we highlighted the usefulness of ostracods as a model proxy to monitor and understand the degradation of reef ecosystems from the coral-dominated phase to the algae-dominated phase.

BlackGate seeks to MSP drill a transect to study the impact of dramatic hydrologic change in Mediterranean–Black Sea connectivity by recovering the Messinian to Holocene (~ 7 Myr) sedimentary sequence in the North Aegean, Marmara, and Black seas. These archives will reveal hydrographic, biotic, and climatic transitions studied by a broad scientific community spanning the stratigraphic, tectonic, biogeochemical, and microbiological evolution of Earth’s most recent saline and anoxic giant.

Sedimentology and micropaleontology analyses provide the dynamic processes that shaped the environmental evolution of the Thapsus coastline (Tunisia) including its lagoon and Roman harbor. The highlights are paleoenvironmental change records from the coast of Thapsus for the last 4000 years, benthic foraminiferal biota recording the dynamic coastal processes, two transgressive events being recognized, and a presented model for the paleoenvironmental evolution.

Short summary
Analyses of foraminiferal assemblages from the Mamanguape mangrove estuary (northern Brazil) revealed highly diverse, species-rich, and structurally complex biotas. The atypical fauna resembles shallow-water offshore assemblages and are interpreted to be the result of highly saline ocean waters penetrating deep into the estuary. The findings contrast with previous studies, have implications for the fossil record, and provide novel perspectives for reconstructing mangrove environments.

Short summary
This study analyzes the diversity of benthic foraminifera at the range expansion front of the invasive species Amphistegina lobifera in Corfu (central Mediterranean). The species has been suggested to impact local diversity and community structures, and our results confirm these effects as soon as A. lobifera exceeds a specific abundance threshold (> 20 %). Nevertheless, we found that the study area reveals an overall high biodiversity that can be attributed to its unique location.
