Summary: China, as the world's largest producer of aquaculture and capture fisheries, has seen significant changes in its aquaculture industry over the years. While there has been a strong relationship between marine aquaculture and wild fisheries from 1989 to 2002, the impact of freshwater aquaculture has increased from 2003 to 2018. Despite the ongoing pressure on marine wild fisheries, China's aquaculture is moving towards a sustainable development pattern with low input and high output.

Summary: This study used population models to investigate the impact of forage fish abundance on 45 marine predator populations and found that only a small percentage of predator populations were positively influenced by increasing prey abundance. This suggests that further limitation of forage fish harvest to levels below sustainable yields would rarely result in detectable increases in marine predator populations.

Summary: This study presents the first circumpolar assessment of mercury contamination in Antarctic marine ecosystems, using Adelie penguins as bioindicators. It found regional variation in mercury concentrations across 24 colonies, with the highest concentrations observed in the Ross Sea due to a higher consumption of fish in the diet. This assessment is important for evaluating the effectiveness of the Minamata Convention on Mercury.

Summary: This study investigated the influence of consumer ontogeny on stable isotope ratios and trophic discrimination factors (TDFs) in African penguins. The results showed that age class affected the stable isotope compositions of whole blood and red blood cells, with chicks and fledglings exhibiting lower delta C-13 and delta N-15 values than juveniles and adults. Plasma, however, demonstrated no effect of ontogeny.

Summary: The stable carbon and nitrogen isotopic compositions of sedimentary organic matter in fish farms were studied to quantify the deposition dynamics of aquaculture-derived organic matter in the sediment. The isotopic compositions of mixed organic matter in surface sediments differed significantly from reference sites, indicating an increased deposition of fish feces or uneaten feed. The contribution of fish feces during farming activities was significantly higher than that of other natural sources.

Summary: Understanding the drivers and consequences of global environmental change is crucial for predicting the effects on ecosystems. This study focuses on the mammal community in Bialowieza Forest and analyzes changes in stable carbon and nitrogen isotope values of hair over seven decades. The study finds a significant decline in hair delta 15N, particularly for herbivores, which is consistent with nitrogen deposition patterns and global-scale declines in non-urban terrestrial ecosystems. The study also detects a global depletion of 13C content in atmospheric CO2, but this effect becomes non-significant after correction. The study highlights the importance of studying mammal communities in natural forests as a way to identify early detection of ecosystem changes.

Summary: The study in French Guiana aimed to investigate the impact of gold-mining activities on mercury concentrations and isotopic signatures in freshwater fish consumed by local residents. Analysis of Hg concentrations and isotopic ratios in fish muscles revealed differences in biogeochemical processes between fish from impacted and pristine areas, indicating potential influences of suspended particles on mercury concentrations. The study also highlighted the potential of Hg isotopes in fish as complementary tracers to understand the sources and processes of mercury accumulation in aquatic ecosystems.

Summary: This study systematically mapped 50 years of scientific literature on 11 forage fish species in Canada's Arctic, Atlantic, and Pacific oceans. The findings highlighted knowledge gaps in forage fish research, including noncommercially exploited species, the life history of eggs, larvae, and juveniles, diets, migration and performance, and the effects of certain pressures. Addressing these knowledge gaps would enhance the application of ecosystem approaches to fisheries management (EAFMs).

Summary: This study improves our understanding of the ecology of Newfoundland herring and its vulnerability to climate change by examining its feeding strategies and stable isotope analysis. The research finds that Newfoundland herring is an opportunistic feeder, primarily consuming amphipods and calanoid copepods, and is sensitive to larval densities. Stable isotope analysis supports the prevalence of herring piscivory in eastern Newfoundland.

Summary: The study investigates the variation of predator-prey mass ratios (PPMR) across different taxa and body sizes, which has significant implications for ecosystem structure, function, and modeling. The findings indicate that different predator species demonstrate varying abilities in transitioning across size-structured prey taxa, leading to differences in their size-PPMR relationship. Incorporating taxon-specific PPMR size dependency in multispecies size-based ecosystem models is suggested to enhance model realism and trophic transfer efficiency.

Summary: Forage fish play a critical role in marine ecosystems, but there is limited information available for many species. This study systematically mapped 50 years of scientific literature for 11 forage fish species in Canada's Arctic, Atlantic, and Pacific oceans, identifying knowledge gaps and the pressures studied in relation to forage fish outcomes. Addressing these gaps would improve the application of ecosystem approaches to fisheries management.

Summary: The study on Magellanic penguins revealed a male-biased sex ratio in broods, influenced by sea surface temperature and potentially female reproductive decisions. Despite the higher cost of rearing male offspring, it does not seem to drive an adaptive bias in the sex ratio of nestlings.

Summary: This study reveals unusually high mercury concentrations in southern rockhopper penguins in the Southwest Atlantic Ocean. The variation in mercury concentrations among colonies is primarily determined by location rather than trophic position. The findings highlight the presence of a mercury hotspot in the Patagonian Shelf, located at the southern tip of South America. Regional and colony-based seabird conservation management is necessary in the presence of high local variability and plasticity in foraging habits.

This study presents updated information on the regional distribution of Chinook salmon, revealing a significant expansion of their range both to the north and south of the previously known colonized areas. This expansion includes major basins draining to both the Pacific and Atlantic coasts and highlights the ongoing invasion of Chinook salmon in South America.

Summary: The lower abundance, biomass, and homogenization of sizes of herbivorous fish caused by overfishing may lead to a disproportionate loss of functions. This study compares isotopic niche breadth, redundancy, and resource use in a herbivorous fish community to investigate the extent to which fishing affects species niche and functions. The results suggest that within the marine protected area, fish may have a greater amplitude of isotopic niche and greater niche overlap. This finding is consistent with previous studies that suggest the delimitation of marine protected areas can contribute to the redundancy of functions and resilience of coral reefs. More isotopic characterization of resources within the MPA is needed to determine if fish are using different resource species or the same ones.

Summary: The research in central-southern Chile found that crustaceans and demersal fish caught with bottom trawling clustered into three groups based on stable isotope values. Different species showed varying degrees of specialization within their own groups, with overlap in isotopic niches between populations. This suggests a complex interaction among benthic and demersal species sharing resources in the habitat, likely supported by a productive pelagic system.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
