Summary: By examining the physiological parameters of corals and zooxanthellae in Sanya Bay coral reef areas in winter and summer, it was found that water temperature and salinity were the main factors affecting their physiological variations. High temperature/low salinity aquatic environment in summer reduced the density and chlorophyll a+c2 content of zooxanthellae, resulting in high superoxide dismutase and caspase3 activities. Turbidity was also an important factor affecting the physiological characteristics of coral-zooxanthellae symbionts. Overall, these findings have important implications for understanding and protecting coral reef communities in Sanya Bay.

Summary: Estuaries worldwide have undergone modifications over centuries, impacting sediment dynamics. The Coos Bay Estuary in Oregon, a small estuary with complex geometry, has experienced significant changes since 1865, leading to alterations in tidal amplitudes, salinity intrusion, and estuarine flow. These changes have resulted in reduced current magnitudes, increased stratification, and the formation of an estuarine turbidity maximum supplying sediment to proximal embayments.

Summary: This study used baited remote underwater stereo-video to investigate 82 demersal teleost species in Australia's continental shelf, finding that seascape relief, water depth, and human gravity were strong predictors of the occurrence of large fishes and the abundance of fishes above the minimum legal size. No-take marine reserves had a positive effect on legal-size fish abundance, while sublegal fishes were best predicted by sea surface temperature gradients.

Summary: Macroalgal habitats contribute to small-scale tropical reef fisheries to a certain extent, supporting a diversity of fish species. Fish associated with macroalgal habitats account for 24% of the catch, but very few species rely solely on macroalgal or coral habitats. Fish in macroalgal and coral habitats have similar life-history traits, and the vulnerability to fishing decreases as the contribution of macroalgae to the catch increases. The study also shows that macroalgae-associated fish can enhance catch size and diversity, which is important in seascapes where coral reefs are being replaced by macroalgal habitats.

Summary: This article describes the characteristics of time series data commonly observed in ecological monitoring and proposes methods for modeling and adaptive monitoring in such settings. Analyzing the monitoring data from Scott Reef, it is found that future monitoring designs do not need to prioritize specific locations and that sampling sites can be omitted based on observed disturbances without substantial loss in expected information gain. As the methods developed in this study are generic, this research has the potential to improve ecological monitoring in collecting complex data over time.

Summary: Consideration of economic outcomes is common in fisheries management globally, but few jurisdictions prioritize economic objectives. Australia's federally managed fisheries have adopted maximum economic yield (MEY) as their primary objective, with biomass-based target reference points used in harvest control rules. In the absence of explicit estimates for biomass-based MEY (BMEY), proxy estimates based on maximum sustainable yield (BMSY) are used. However, estimating BMEY in multi-species fisheries is challenging due to assessments conducted at the individual species level, while economic activity spans across species. This complexity is further compounded in fisheries with multiple fishing gears and targeting practices. Using an age-structured bioeconomic model, this study estimates BMEY for key species in a multi-species, multi-metier fishery, revealing higher optimal biomass levels compared to the current proxy-based system, with economic targets sensitive to changing prices and fishing costs.

Summary: The eastern Australian stock of orange roughy, a deep-water, long-lived species, experienced significant exploitation in the late 1980s and early 1990s, resulting in a drastic reduction in biomass. The fishery was closed in 2006, but recent assessments have shown an increase in the stock's biomass, leading to its reopening in 2015. The assessment process is controversial and closely scrutinized, using the Stock Synthesis platform and key inputs such as catch data, acoustic surveys, and age-composition data.

Summary: The term data-limited fisheries refers to situations where there is insufficient data to support a fully integrated stock assessment model. These conditions can range from a complete lack of data to reliable quantitative assessments, and can also be constrained by limited resources. The DLMapper tool is introduced to identify the level of data limitation in a fishery and provide guiding principles for management. By outlining the conditions that create data-limited situations and linking them to guidance, this approach aims to improve the communication and development of limited stock assessment in fisheries management.

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.
