Abstract Effective management and mitigation of multiple human impacts on marine ecosystems require accurate knowledge the spatial patterns activities their overlap with vulnerable habitats. Cumulative impact (CI) mapping combines information intensity extent habitats vulnerabilities to those stressors into an intuitive relative CI score that can inform planning processes ecosystem‐based management. Here, we mapped potential CIs 45 from five sectors (climate change, land‐based, marine‐based, coastal, commercial fishing) 21 in Atlantic Canada's Scotian Shelf bioregion. We applied uncertainty sensitivity analysis assess robustness results identify hot cold spots CIs. Nearly entire bioregion experiences activities, high were frequently associated stressors. varied widely across habitats: scores >30 m deep dominated by climate change fishing, while nearshore influenced a much wider range all sectors. When standardized area, coastal had among highest scores, highlighting these despite relatively small emphasizing importance multisector approach when managing ecosystems. Robust (i.e., areas insensitive alternative modeling assumptions simulated data quality issues) occurred mostly where high‐intensity overlapped highly biogenic In contrast, robust offshore. Overall, our emphasize need consider protection demonstrates that, many areas, targeting only one activity will be insufficient reduce overall impact. The map useful highlight impacts, provide for ecological indicator development, establish baseline current state use

Biodegradable plastics can mitigate plastic waste issues by undergoing hydrolysis and microbial digestion. However, biodegradable face unjust accusations of not decomposing in natural environments, including barren soil or cold oceans, under unsuitable conditions. In this study, we simulated end-of-life products real-field seawater Replenishing vermicompost horticultural topsoil (3:7 wt ratio) activated growth, resulting significant degradation. fertile soil, polycaprolactone (PCL) poly(butylene succinate) (PBS) required fewer than 6-months, for complete degradation, while adipate-co-terephthalate) (PBAT) with more 51 mol% terephthalate content was rarely degraded. an artificial aquarium, PCL degraded at the rate 30 μm per month. The degradation bioplastics enclosed coarse nets superior to that fine nets, owing higher aeration water circulation.

Floating microplastic debris are found in most marine environments around the world. Due to their low density and high durability, plastic polymers such as polyethylene, polypropylene, polystyrene serve stable floating substrates for colonization of diverse communities organisms. Despite abundance oceans, it is not clear how geographical location season affect composition its bacterial microbiome natural environment.To address this question, were collected from sea surface near estuaries Mediterranean Sea (Israel) Atlantic Ocean (Portugal) during summer winter 2021. The physical characteristics, including shape, color, polymer composition, analyzed taxonomic structure was characterized using a high-resolution metabarcoding pipeline.Our results, supported by previously published data, suggest that plastisphere highly ecosystem which strongly shaped spatial temporal environmental factors. had highest impact on characteristics followed season. Our analysis showed great variability between different with very limited "core."This notion further emphasizes importance studies locations and/or seasons characterization identification plastic-associated species.

However, scaling task requires considerable effort specific equipment. This experimental study proposes evaluates three methods estimate from aerial images, employing different levels categorization. The most promising approach (accuracy 80 %) combined outcomes manual image screening with generalized mean (14 g) derived studies in literature. Although other two returned values same magnitude as ground-truth, they were found less feasible for aim. represents first attempt assess using remote sensing technology. Considering exploratory nature this study, further research is needed enhance reliability robustness methods.

Abstract Mismanaged plastic waste (MPW) and urban flooding are typically considered distinct environmental challenges. However, there notable links between growing quantities of MPW the rising incidence floods in cities. A majority people now live cities, especially along coastlines estuaries where residents both vulnerable to significant sources waste. Predicted increases frequency severity heavy rainfall associated with anthropogenic climate change coincide global MPW, much which is discharged into water bodies sea. Given urgent expanding nature these issues, understanding impacts on solid management vice versa crucial. Social‐ecological systems (SES) thinking calls for a holistic approach relationships interactions human actors can result dynamic emergent outcomes. In this review paper, we make first step towards better by synthesizing emerging quantitative qualitative research particular aspects such interactions. More needed explicitly focuses elaborates interactions, also consider potential relations across scales (from local) over long short timeframes. We conclude that an SES visible novel possibilities interventions context specific sensitive MPW.
