Summary: This study examines the impact of global change factors on the abundance of microbial mediators of nitrogen cycling pathways in soil. The results show that most nitrogen-cycling genes are resistant to climate change and nutrient addition, but the addition of nitrogen and its combination with other global change factors significantly increase the abundance of ammonia oxidizer bacteria. Additionally, changes in the abundance of soil microbes and nitrogen-cycling genes are closely associated with changes in soil pH.

Summary: This paper explores the application of the concept of CURL borrowed from vector calculus to the zoom motion detection and classification problems. The proposed method utilizes interframe block motion vectors extracted from compressed bitstream and analyzes them by partitioning the motion vector field, quantizing the block motion vectors, and converting them into complex motion vector space. The estimated CURL provides information about the enclosed area between quadrant motion vectors, which is used for separating zooming and non-zooming camera types. Zooming camera frames are further classified into zoom-in and zoom-out types based on the direction information extracted from the CURL of the velocity field. Experimental validation shows the superiority of the proposed features extracted from CURL.

Summary: Coral reefs and associated fish populations are at risk of extinction by the end of the century without additional long-term strategic conservation efforts. This study examines public willingness to pay for global coral and reef fish conservation in 12 countries of varying income and tropical reef proximity. The findings suggest that public preferences are not aligned with effective conservation measures, with individuals being more willing to act when reefs are in serious decline and preferring hands-on restoration measures over other approaches. Conservation demand is highest in countries with lower income. These results have important implications for policymaking decisions.

Summary: Coastal habitats are facing challenges of decreased seawater pH and increased temperature due to anthropogenic climate change. The Caribbean king crab plays a crucial role in Western Atlantic reefs by grazing macroalgae that competes with coral. A laboratory experiment found that juvenile king crabs are tolerant to changes associated with climate change, suggesting they could benefit coral reef restoration efforts to make them more resilient to warming and acidic oceans.

Summary: The oceans have been acidifying due to the absorption of anthropogenic CO2, with the surface ocean aragonite saturation state and pH declining over the past four decades. The main driver of these trends is the increase in dissolved inorganic carbon from anthropogenic CO2 uptake, with surface warming contributing to the decrease in pH. Regional differences in the ability to take up and buffer anthropogenic CO2 result in variations in the long-term trends.

Summary: Research on marine invertebrates has shown that the interaction between body extensions and limb motion plays a crucial role in shaping evolution and biomechanical performance. In the study of dorsal thoracic spines, it was found that amputated individuals swam slower, with lower efficiency, and displayed altered limb beat patterns. These findings suggest that body extensions have biomechanical implications for larval performance and potentially influence evolutionary form.

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.
