Summary: This study demonstrates that as trophic levels increase, biomagnification of MMHg becomes more significant. Trophic magnification factors show opposite spatial patterns between lower and higher trophic levels. With a warmer future climate, global average TMF is projected to increase, leading to higher MMHg exposure for top predators, such as humans, if no mitigation measures for Hg emission are implemented.

Summary: This study investigated the trophic dynamics of Hg in the polluted Baltic Archipelago Sea using trophic magnification and biomagnification factors. The results showed overall biomagnification of THg, with higher TMFs in pelagic species compared to benthic species when excluding homeotherm birds. However, when including homeotherm birds, the difference in TMFs between benthic and pelagic species disappeared. The study emphasizes the importance of considering ecological and ecophysiological traits when studying trophic contaminant dynamics.

Summary: This study investigated the variability of concentrations and distributions of PCB and PBDE congeners in 26 species from different locations around Scotland. The study found clear differences in congener distribution between sample categories and species, influenced by physiological processes and eco-biological parameters. Trophic magnification was observed for the ICES-7 PCBs and BDE47 using the traditional method, with CB52 showing the highest degree of magnification. The unbalanced dataset influenced the calculated trophic magnification factor (TMF) and sometimes the overall conclusions of congener biomagnification. The use of a balanced method is recommended for accurate TMF calculations, particularly in regional comparisons with difficult sampling requirements.

Summary: Mercury biomagnification in aquatic ecosystems, especially in alpine regions like the Qinghai-Tibetan Plateau, is poorly understood. This study investigates the biomagnification potential of mercury in the food web of the Q-T Plateau and finds that the mercury concentrations exceed consumption guidelines in 26.75% of fish samples. The biomagnification rates on the Q-T Plateau are generally higher than global averages and are positively correlated with sediment mercury, elevation, and population density.

Summary: Although many attempts have been made to improve the accuracy of trophic magnification factor (TMF) and biomagnification factor (BMF) for assessing pollutant bioaccumulation, this study suggests an improved BMF (BMF') for mercury bioaccumulation in freshwater fish. The results show that the values of BMF' are generally higher than TMF, indicating that it is a more reliable index for risk assessment. This ecological approach provides novel insights into the behavior and trophic transfer of pollutants like mercury.

Summary: The decline of shark populations in the world ocean has unpredictable effects on ecosystem structure and function, necessitating new ecological information for a better understanding of the role of sharks in their habitats. Research has found that many shark species primarily forage in the mesopelagic area, but the extent to which different pelagic sharks rely on this habitat has been overlooked. By using mercury stable isotopes in the muscle of pelagic sharks, it is possible to reveal their food partitioning and the relationship between foraging depth and resource competition.

Summary: Spatial variability in fish food-web structure in the Wadden Sea was studied by comparing stomach content and bulk stable isotopes of fish species caught in the Ems and Marsdiep basins. The findings showed that most fish species in both basins were generalist feeders, with a few key prey species driving the food web. The study also revealed spatial differences in prey preferences, which were likely influenced by local predator and prey abundances.

Summary: A new generalized depletion model was developed for the rapid life cycle of Octopus vulgaris in a co-managed small-scale fishery in northwest Spain. The study found high density-dependence in the fishery stock, leading to overcompensation and making the maximum sustainable yield (MSY) inapplicable. It is suggested that harvest rates based on mean latent productivity are more appropriate and sustainable for fluctuating stocks.

Summary: The detrital-based food web in abyssal plains relies on deposit feeders as secondary consumers, with their gut contents mainly consisting of living biomass of heterotrophic prokaryotes. The guts of deposit feeders act as hotspots of organic matter, forming a unique food source distinct from the surrounding surface detritus, and increasing the food-chain length in detritus-based ecosystems.

Summary: In this study, the dynamics and connectivity of local populations of the stalked barnacle P. pollicipes along the Iberian coast were assessed using genetic markers. The results showed high genetic diversity among adults, while juveniles exhibited a more pronounced genetic structure. The lack of spatial genetic heterogeneity in adults may be due to overlapping generations of settlers from different geographic origins, while the genetic differentiation of juveniles may be influenced by hydrodynamics producing chaotic genetic patchiness. Most of the genetic heterogeneity in juveniles was found in Galicia, possibly indicating an admixture between distinct metapopulations or an old refuge for northern populations. These findings highlight the importance of considering genetic variation and larval exchanges in management and conservation plans for P. pollicipes in the Iberian Peninsula.

Summary: Research has found that Turritopsis dohrnii has the ability to regenerate, and this ability is associated with variations and expansions of several genes related to replication, DNA repair, telomere maintenance, stem cell population, and intercellular communication. Furthermore, during its life cycle reversal process, silencing of polycomb repressive complex 2 targets and activation of pluripotency targets are proposed to be key factors in T. dohrnii's ability to undergo rejuvenation.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
