Whether considered as a risk for human health or as ecological tracers, contaminants' concentrations measured in fish muscles are commonly expressed relative to wet or dry mass. Comparison of results required conversion factors (CF) but accurate values are scarce and case-specific. The present paper is aimed at investigating errors linked with the use of the theoretical value. Muscles dry and wet masses were measured in 15 fish species to determine the actual CF. Most CF were lower than the theoretical wet:dry ratio of 5 classically used, with variations at individual and species level. Muscle lipid content (inferred by C/N ratios) was a crucial factor explaining discrepancies, claiming for caution when working with lipid-rich species. The observed variability demonstrated that using the theoretical CF may be inaccurate, when actual CF largely differs from the theoretical value. Dedicated measurement is the better approach when accuracy is required.

Inferences to estimate consumer's diet using stable isotopes: Insights from a dynamic mixing model

Marine Ballutaud, Morgane Travers-Trolet, Paul Marchal, Stanislas F. Dubois, Carolina Giraldo, Andrew C. Parnell, M. Teresa Nuche-Pascual, Sebastien Lefebvre

Summary: Stable isotope mixing models are used to reconstruct animal diet, but current research neglects the dynamics of isotopic ratios and the impact of time lag on diet reconstruction. By using a dynamic mixing model, it is possible to more accurately estimate the consumer's diet and avoid misinterpretation in ecosystem functioning and food-web structure analysis.

Trace elements, dioxins and PCBs in different fish species and marine regions: Importance of the taxon and regional features

Aourell Mauffret, Tiphaine Chouvelon, Nathalie Wessel, Pierre Cresson, Daniela Banaru, Jerome Baudrier, Paco Bustamante, Rachida Chekri, Petru Jitaru, Francois Le Loc'h, Benoit Mialet, Vincent Vaccher, Mireille Harmelin-Vivien

Summary: Chemical contaminant concentrations in wild organisms are used to assess environmental status, but they are challenged by intra- and inter-species variability and regional differences. This study monitored concentrations of trace elements and organic pollutants in 8 fish species from three French regions, aiming to identify contaminated species or regions and determine how to account for variability in environmental assessment. The results showed higher concentrations in benthic and demersal piscivores, while lipid-normalized concentrations were similar in most teleost species. Regional differences were observed, with higher concentrations in the Eastern English Channel and Gulf of Lions compared to the Bay of Biscay. Taxa-specific thresholds might be a more practical approach for environmental assessment than normalizing to trophic levels.

Effect of temperature and CO2 concentration on the morphogenesis of sagittal otoliths in Atlantic herring (Clupea harengus) larvae

Kelig Mahe, Lea Justine Joly, Solene Telliez, Jose Luis Zambonino-Infante, Cedric Leo Meunier, Kirsteen M. MacKenzie, Carolina Giraldo

Summary: Otoliths are important biomarkers for fish growth, and climate change may affect their calcification and morphology. However, the shape of otoliths seems to be unaffected by climate change. The onset of otolith morphogenesis is fixed, but the relationship between otoliths and fish size is dependent on the environment.

Different mechanisms underpin the decline in growth of anchovies and sardines of the Bay of Biscay

Andy Boens, Bruno Ernande, Pierre Petitgas, Christophe Lebigre

Summary: The declines in growth of European anchovy and sardine are found to be related to both fishing pressure and environmental changes. The adaptive response is significant in anchovy, with larger individuals selectively disappearing and growth declining when biomass increases. In contrast, sardine shows a plastic response, with higher growth associated with increasing biomass and changes in food availability.

Smaller herring larval size-at-stage in response to environmental changes is associated with ontogenic processes and stress response

Lea J. Joly, Maarten Boersma, Carolina Giraldo, David Mazurais, Lauriane Madec, Sophie Collet, Jose-Luis Zambonino-Infante, Cedric L. Meunier

Summary: The development and physiology of herring larvae were monitored in response to warming, acidification, and different food quality treatments. The experiment showed that warming and acidification resulted in a stress response at the molecular level and a decrease in herring larvae size-at-stage. The findings suggest that the predicted warming and acidification environment is stressful for herring larvae, potentially affecting their survival and recruitment.

Aliya Baidourela, Qian Sun, Gongxin Yang, Umut Halik, Zhongkai Dong, Kaixu Cai, Guili Sun, Wenya Zhang, Sisi Cheng

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.

Microplastic inputs to the Mediterranean Sea during wet and dry seasons: The case of two Lebanese coastal outlets

Rosa Sawan, Perine Doyen, Florence Viudes, Rachid Amara, Celine Mahfouz

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.

Trait-based classification and environmental drivers of phytoplankton functional structure from anthropogenically altered tropical creek, Thane Creek India

Revati Hardikar, C. K. Haridevi, Shantaj Deshbhratar

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.
