Summary: Moonlight has been shown to suppress coral spawning, with spawning typically occurring 5 days after shading. Laboratory experiments demonstrate that a dark period between day-light and night-light conditions can eliminate the suppressive effect of night-light on spawning. The period of darkness between sunset and moonrise during the lunar cycle triggers synchronized mass spawning of corals in nature.

Summary: Differences in selective pressures and the energetic cost of gametes may lead to sexual dimorphism in gonochoristic corals. This study found sexual dimorphism in the corallites of the gonochoric broadcast spawner Porites lobata, with males having larger corallite area. Phenotypic modularity analysis showed that the integration of skeletal traits differs between sexes in both P. lobata and its congener P. panamensis, suggesting the degree of corallite integration may vary with reproductive mode.

Summary: Loss of foundation reef-corals is damaging reef communities globally, leading to a decline in ecosystem function. Active intervention and effective coral restoration techniques are needed to enhance coral recruitment and density. Enhancing larval supply significantly increases settlement on reefs, facilitating rapid re-establishment of breeding coral populations and enhancing fish abundance.

Summary: We investigated the effect of seawater temperature on coral spawning timing for four species of scleractinian corals. Monitoring in Lyudao, Taiwan, revealed that spawning always occurred between April and June, coinciding with a rapid rise in seawater temperature to 26-29 degrees C. The timing of spawning was influenced by both daily and hourly seawater temperatures, with earlier spawning observed at warmer sites. Transplant experiments confirmed the role of temperature, as corals at the warmer site spawned earlier than those at the cooler site. These findings highlight the pervasive influence of temperature on coral reproductive processes.

Summary: The discovery of multi-species synchronous spawning on the Great Barrier Reef in the 1980s led to efforts to document spawning times globally. The Coral Spawning Database (CSD) compiles data from over 100 sites in the Indo-Pacific region to provide open access for studying coral reproductive biology. The CSD aims to accelerate understanding of coral reproduction and to establish a baseline for evaluating future changes in reproductive patterns.

Summary: Deltas and estuaries worldwide are facing the challenge of capturing sufficient sediment to keep up with relative sea-level rise. Anthropogenic interventions in the urbanized Rhine-Meuse Delta of the Netherlands have led to a negative sediment budget since the 1980s. The increase in dredging activities in ports and harbors, as well as changes in sediment composition, have important implications for navigation, ecology, flood safety, and management of sediment in the system.

Summary: Research on the sub-lethal effects of coal contamination on tropical marine organisms, including fish, showed that high coal concentrations significantly affect the aerobic metabolism and gill structure of marine fish species. However, most observed effects occurred at high coal concentrations that are unlikely under most coal spill scenarios. Future studies should focus on chronic exposures to lower concentrations of coal contamination to further understand its impacts.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
