Summary: The study investigated the abundance and diversity of copepods associated with foundation species in different physiochemical environments at the active vent site ABE, finding that species richness and Shannon diversity were significantly higher in the Bathymodiolus habitat with lower temperatures, sulfur concentrations, and higher oxygen levels, driven by a community comprised mostly of habitat generalists.

Summary: Desmas-bearing demosponges known as lithistids have heavily silicified skeleton and are typically found in bathyal environments of warm and tropical areas, but may also occur in certain shallow marine caves. This study reports the presence of two lithistid species in the north-eastern Mediterranean marine caves, with an unexpected association between lithistids and freshwater springs leading to their development. Age estimation suggests that the large populations of lithistids discovered in the caves could be as old as 769-909 years, having colonized the caves from adjacent deep-water areas after the last glaciation.

Summary: For the first time, benthic foraminifera and geochemical proxies were used to characterize oceanographic conditions in cold-water coral ecosystems. The study revealed higher diversity of foraminifera near corals and indicated important nitrogen fixation and degradation processes in the region. Advection of freshly exported organic matter was found to be more effective at the mound top compared to the base or off-mound.

Summary: This review summarises the research outcomes of the past 30 years on the environmental factors influencing the deep benthic communities in the Eastern Mediterranean Sea. The availability of food and sediment texture were found to be the key factors shaping the structure of these communities. Additionally, recent findings on the ecological services provided by hydrocarbon-degrading bacterial consortia in the biodegradation of crude oil constituents are featured.

Summary: This study discovered new brine pools in the ultraoligotrophic Eastern Mediterranean Sea using geophysical analysis and seafloor surveying. The composition of these pools, including salinity and chemical composition, was analyzed, and possible formation processes were proposed.

Summary: By analyzing samples of epibenthic foraminifera from the eastern Arabian Sea, this study reveals the variations of stored CO2 and carbonate ion in deep waters from the Last Glacial Maximum to the Holocene. The rise in CO2 and carbonate ion during the deglaciation and the mid-Holocene is attributed to the release of glacial CO2 from deep waters through the Southern Ocean and via intermediate waters of the eastern Arabian Sea.

Summary: Deep-sea trenches are a largely unexplored frontier for biodiversity, with meiofauna like kinorhynchs representing a significant gap in our understanding. A study in the Atacama Trench revealed six species of mud dragons, including a new species. The results suggest geographic isolation and limited connectivity between deep-sea trenches and other habitats in terms of sediment dwelling fauna biodiversity.

Summary: This article reports the discovery of three new species of Zosime and one new species of Peresime from the benthic ecosystem samples in the southwestern Gulf of Mexico. The researchers found that these new species have unique characteristics that differentiate them from known species, and discuss the global diversity and distribution of Zosimeidae.

Summary: Global warming is causing a net loss of biodiversity in the Mediterranean Sea, particularly on the Israeli shelf, with only a fraction of historically present native species remaining. As climate warms, this native biodiversity collapse is predicted to intensify and spread geographically, but may be offset by Indo-Pacific species entering from the Suez Canal. The impact of climate change and biological invasions has led to the formation of a 'novel ecosystem' that cannot be restored to historical baselines.

Summary: This study investigates the variations of the surface Moho beneath the northwestern Arabian plate using Bouguer gravity data and a 3DINVER program. The calculation results show that the maximum Moho depth is over 40 km in the western Arabian shield and the minimum depths of 16-20 km are mainly located beneath the Mediterranean Sea. The study also innovatively implements an exponential density contrast decrease in the sediment-basement interface, resulting in a more accurate representation of the subsurface structure and providing valuable insights into the geodynamic processes and seismogenic potential of the area.

Summary: Worldwide legislation emphasizes the importance of monitoring the health of aquatic ecosystems based on the response of biological quality elements to environmental conditions. Recent studies have explored the use of new biological quality elements and methodologies, such as benthic foraminifera and nematodes, as well as environmental DNA, to efficiently assess the health of transitional and marine ecosystems. These methods still require further calibration, but they are promising tools for environmental biomonitoring and can address key ecological knowledge gaps.

Summary: This study analysed macrofaunal foraminifera in three abyssal sites in the Clarion-Clipperton Zone, finding that monothalamids were important components of the foraminiferal assemblages. Species richness and diversity were higher at impacted and resedimented sites compared to the control site, but the differences were not significant.

Summary: This study evaluates how local iron enrichment affects small benthic biota (bacteria, meiofauna) at the deep seafloor. By analyzing sediment samples and associated infauna along a short transect, the researchers found that iron-enriched sediments had lower densities and biomasses of bacteria and meiofauna compared to unaffected sediments. The structure of bacterial and nematode communities also differed significantly between iron-enriched and unaffected sediments, with lower taxonomic richness and diversity observed in sediments closest to the iron source.

Summary: This study is the first to investigate the presence of microplastics in sediment, water, and benthic organisms (foraminifera) of a marine cave in the Gulf of Orosei, Italy. The microplastics identified in the samples consisted mainly of PVC and polyethylene fragments and fibers. The source of these microplastics was likely the sea rather than seasonal freshwater supplies. Furthermore, the study found that foraminifera collected and incorporated microplastic items into their shells. This study provides evidence that marine caves can act as collectors of microplastics and highlight the potential impact on protists.

Summary: The study examined sinking particle flux data collected in the deep Ierapetra Basin for a three-year period and investigated the seasonality and interannual variability of particle fluxes. Results showed an increase in POC flux in spring 2012 related to extreme atmospheric forcing. Lipid biomarkers indicated a significant contribution of both natural and anthropogenic POC reaching the deep-sea floor.
