Summary: Coral reefs, as the most spectacular underwater creation, play crucial roles in ecosystem functioning and coastal community livelihood. However, marine debris poses a severe threat to these sensitive habitats and their associated organisms. Despite scientific attention, data regarding the sources, abundance, distribution, and potential consequences of marine debris on reef ecosystems are lacking. This review aims to provide an overview of the current status and impacts of marine debris, with emphasis on sources, distribution, affected species, and management strategies, as well as highlighting the adhesion mechanisms and diseases caused by microplastics to coral polyps.

Summary: Previous studies have believed that coral reef islands will gradually become uninhabitable due to sea level rise, but GIS-based analyses have shown that these islands are highly dynamic landforms and can adjust their shorelines. Research in the Maldives has found that despite sea level rise, 53% of the islands have increased in size, 25% have eroded, and 22% have remained stable. These findings suggest that coral reef islands have the ability to adapt to sea level rise and increase groundwater storage, providing valuable ecosystem services.

Summary: The degradation of shallow ecosystems has led to a need to study and understand the biodiversity and functioning of Mesophotic Ecosystems. However, most research has been limited to tropical regions and focused on species, neglecting other important aspects of biodiversity. By studying a subtropical island in the Atlantic Ocean, we found that fish communities in mesophotic black coral forests (BCFs) differed in functional structure compared to shallow reefs, indicating the importance of specific management and conservation strategies for preserving the unique biodiversity and functionality of mesophotic BCFs.

Summary: Ocean acidification threatens carbonate-dominated marine systems, like tropical coral reefs, by affecting the ability of organisms to calcify. To assess coral reef flat susceptibility to open ocean acidification, it is crucial to understand the dynamics between carbonate chemistry of open ocean waters and local ecological and hydrodynamic processes. This study measured variations in seawater pH and temperature along coral reef flat transects, complemented by surveys of benthic community composition and reef flat bathymetry. Results showed that reef flat hydrodynamic processes determine spatial pH modifications, with little influence from benthic community composition. As reef flat pH largely mirrors ocean conditions, ocean acidification has an unhindered impact on narrow fringing reef flats.

Summary: The study on a reef island in the Great Barrier Reef over a 57-year period shows that while some shorelines experience erosion, the overall stability is maintained. Human impact causes localized increase in shoreline change but has minimal impact on stable shorelines. There is a significant decreasing trend in island planform area, but the interval between sampled shorelines has a strong effect on the change recorded.

Summary: The response-and-effect framework is a trait-based approach that aims to analyze the mechanistic links between ecosystem disturbances, species' traits, and ecosystem processes. A review of coral reef fish traits literature shows a focus on linking response traits to disturbances, with fewer studies connecting effect traits to ecosystem processes. Size and diet of fish are identified as common traits in the literature, crucial for understanding both disturbance and process in ecosystems.

Summary: This study uses Cu and Zn isotopic compositions as proxies to investigate sources and metal transfers in the planktonic food webs of the Mediterranean Sea. The findings suggest that geogenic particles are ubiquitous in plankton assemblages and that the planktonic food web enriches heavy isotopes of Cu and Zn at higher trophic levels. It is also observed that biogeochemical processes may impact the isotopic compositions of Cu and Zn in the planktonic community.

Summary: We evaluated the spatial variability in the size structure, community composition, primary production, and carbon fluxes of phytoplankton in the Gulf of Gabes. The results showed high concentrations of nutrients, chlorophyll a, and primary production, indicating eutrophic conditions. The distribution of phytoplankton community was influenced by nutrient gradients, with smaller fractions dominating in the northernmost zone and larger fractions prevailing towards the South and offshore. The herbivorous protozooplankton and metazooplankton were more abundant in these zones, leading to increased herbivory and carbon export.
