First routinely deployed in 1931 the Continuous Plankton Recorder (CPR) technology has established the most extensive, marine biological sampling programme in the world. With more than 90 years of sampling, over a total of 8 million nautical miles covered and 500 000 curated samples, the CPR survey provides a gold mine of information available to marine researchers. Such information is likely to exponentially increase thanks to new cutting-edge molecular technologies that are beginning to be applied on CPR samples. In this review we aim to address the exciting developments that the genomic revolution is having on CPR applications from the study of marine microbiome to ocean plankton communities leading to a new 'digital era' of the global ocean CPR observation programme.

Microbial communities play a crucial role in the functioning of freshwater ecosystems but are continuously threatened by climate change and anthropogenic activities. Elevated temperatures and salinisation are particularly challenging for freshwater habitats, but little is known about how microbial communities respond to the simultaneous exposure to these stressors. Here, we use mesocosm experiments and amplicon sequencing data to investigate the responses of pelagic and benthic microbial communities to temperature and salinity increases, both individually and in combination.

Assessing pollutant fate in highly impacted industrial harbors is challenging, yet crucial for effective ecological risk assessment. This study analyzed key aspects of pollutant fate: spatial distribution, sources, and biomagnification for the organic pollutants polycyclic aromatic hydrocarbons (PAHs), phthalate esters (PAEs), and alkylphenols (APs) in phytoplankton and zooplankton across Kaohsiung Harbor, Taiwan. Spatial variability identified harbor entrances and marine outfall as key hotspots for all three contaminant groups.

Here we present the study of 48 new dinoflagellate cyst assemblages from the west Antarctic shelf sediments on a wide longitudinal scale, with a greater representation of ice-proximal sites, and provide a comprehensive overview of their distributional patterns and multiple environmental forcing factors. We find a strong spatial heterogeneity in the dinoflagellate cyst distribution patterns; 1) the northern Antarctic Peninsula region is dominated by Islandinium? minutum, Selenopemphix antarctica and Brigantedinium spp. in association with meltwater-induced stratification and high diatom productivity, 2) the Bellingshausen-Amundsen Seas is dominated by Gymnodinium microreticulatum and Selenopemphix sp.

Post-mining lakes in the Czech Republic, especially in North Bohemia, represent distinctive opportunities for ecological transformation of degraded landscapes. Such lakes form in closed open-pit mines, where they create new water and wetland habitats. The ecological development of such systems is strongly affected by water quality, which is often impaired by residual contamination from mining and nutrient imbalances.

Plankton communities form the foundation of marine food webs, determining the ecosystem carrying capacity and the services they provide. Their spatial distribution patterns are highly dynamic, influenced by ocean stratification, mixed layer depth, and nutrient availability. In this study, we combined an advanced imaging system with a machine learning model to explore how environmental factors shape plankton distribution on the South Brazilian Shelf.
