Summary: This review provided an overview of artificial turbulence generation methods and quantification techniques used in phytoplankton-turbulence laboratory experiments. Most experiments feature quantification of turbulence, with turbulent dissipation rates recommended for consistency with physical oceanographic and limnological observations. Dinoflagellates were the primary phytoplankton group studied due to their propensity for forming harmful algal blooms and sensitivity to turbulence.

Summary: Establishing robust estimates of polar marine biodiversity is important for interpreting future changes in the Arctic. Despite the recent increase in scientific expeditions, the region remains relatively underexplored, particularly in terms of small species like protists, fungi, and many small invertebrates known as meiofauna. The study used a metabarcoding approach to assess metazoan biodiversity in sea ice and sediment samples from Utqiagvik, Alaska, and found that season and habitat are significant predictors of meiofaunal biodiversity, supporting the use of meiofauna as indicators of climate change.

Summary: Although bird species showed a decline after habitat disturbance from logging and construction, there were positive signs of recovery during the inundation and operation phases. The recolonisation of species indicates that the bird community is still recovering, with differing species composition across phases due to changing habitat conditions.

Summary: This study investigates the use of graded iron ore tailing sands (GIOT) as aggregates in cemented mortar to reduce the pollution of iron ore tailings (IOT) and shortage of river sands. The fresh and hardened properties of graded tailings cemented mortar (GTCM) with partial replacement of standard sands (SS) by GIOT were studied. It was found that increasing the GIOT content leads to reduced fluidity and increased apparent density of fresh GTCM.

Summary: Speciation in Pterodroma petrels is believed to be influenced by ecological segregation rather than strict allopatry. However, the ongoing distributional range shifts due to global change have raised questions about how the separation of breeding islands and foraging grounds can be maintained. This study found that gene flow occurs across species boundaries in Pterodroma petrels, suggesting that incomplete allopatric speciation processes may be reversed in secondary contact zones. These findings emphasize the importance of considering fine ecological structures for biodiversity mapping and conservation policies.

Summary: Through measuring the physical properties of tailings and conducting experiments, it was found that the underflow concentration of tailing slurry is related to the particle size of tailings. Three relation equations were derived through regression analysis, and the predicted values showed a relative error within 6.1% compared to the test values, indicating the feasibility of these equations. The underflow concentration of the deep cone thickener can be predicted by measuring the particle size of the tailings.

Summary: Using tailings to prepare constructive materials is important for sustainable development of the mineral processing industry. This study explored the possibility of preparing tungsten tailing-based geopolymers. Various analyses were conducted to characterize the composition, bonding, microstructure, and properties of the geopolymers. Results showed that geopolymers with a mixture of tungsten tailings and metakaolin had good compressive strength and could immobilize heavy metals efficiently. This research provides a new idea for the utilization of tungsten tailings on a large scale.

Summary: Catchment-scale plastic pollution assessments provide insights into the sources, sinks, and pathways of plastic pollution. We propose an approach to quantify macroplastic transport and density in the Odaw catchment, Ghana, and find that the urban riverine zone has the highest transport, while the urban tidal zone has the highest riverbank and land macroplastic density.

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.
