Summary: The seasonal fluctuation of seawater in coastal areas has a close interaction with freshwater, which can affect the behavior of contaminants. This study investigated the transport and transformation of soil colloid and associated Cr during alternating fluctuations of freshwater and seawater through laboratory experiments and numerical simulations. The results showed that seawater fluctuations generated more and larger-sized colloids, which facilitated the transport and transformation of Cr.

Summary: Measuring energy consumption is crucial for evaluating the risk of workers and improving workstyle during green area management. Unlike sports activities, there have been few studies on assessing physical fatigue in this sector by measuring human body function parameters and oxygen consumption. This study aims to measure the energy cost of weed control using the wearable telemetry system Cosmed K4. Twelve male workers were monitored during weed control work using a brush cutter, and the study shows that using facilitating tools like brush cutters results in low energy metabolism rates, averaging 119 Wm-2.

Summary: Pb is extensively used in Bangladesh and has significant effects on aquatic organisms. Exposure of Lamellidens marginalis to different concentrations of Pb(NO3)2 resulted in altered growth performance, hemocyte counts, and histomorphological abnormalities in vital organs. The highest mortality and pathological alterations were observed in the treatment groups with higher doses of Pb. The intrusion of Pb(NO3)2 in the living medium alters the physiology and morphology of the tropical pearl mussel.

Summary: Many ectotherms have shown a reduction in maximum body size in parallel with climate warming, with some fish species forecasted to decline by 14%-24% by 2050. Current research suggests that the decline in fish body size may be related to the gill-oxygen limitation hypothesis, but further investigation into other factors is needed.

Summary: The expression patterns of NKA & alpha;1-isoforms in the gill of chum salmon acclimated to freshwater and seawater were examined using in situ hybridization chain reaction. The results showed that the NKA & alpha;1c isoform was ubiquitously expressed in gill tissue and not affected by salinity. In freshwater, lamellar ionocytes expressed cytoplasmic NKA & alpha;1a and nuclear NKA & alpha;1b transcripts, while in seawater, filament ionocytes expressed cytoplasmic NKA & alpha;1b as the major isoform. The study also demonstrated the plasticity of ionocyte populations in chum salmon, indicating their ability to switch ionocyte types in response to salinity demands.

Summary: In this study, the effects of two freshwater photoperiod regimes and four transfer times to seawater on Atlantic salmon smolt development and growth were assessed. The results showed that smoltification and growth in freshwater were slightly affected by the photoperiod treatment but greatly influenced by low water temperature. The growth rate in seawater was highest in the groups that experienced delayed growth in freshwater, indicating the potential benefits of transferring larger smolts to seawater.

Summary: Agricultural activities play a significant role in contributing to microplastic pollution in water. However, there are limited studies investigating the impact of irrigation on the fate of microplastics in agricultural systems. This study examined the distribution and community composition of microplastics in agricultural soil, surface water, and sediment before and after irrigation in a typical irrigation area of the Yellow River. The results showed that microplastics were present in all examined sites, with increased levels in surface water and sediment after irrigation. Irrigation also facilitated the vertical migration of microplastics into deep soil layers. Furthermore, irrigation altered the correlation between soil properties and microplastics. Overall, this study highlights the secondary pollution caused by river water irrigation and the need to develop strategies for microplastic pollution control in agricultural soil.

Summary: In this study, we investigated the changes in the transcriptome and epigenome of a long shelf-life tomato landrace during post-harvest. We discovered global changes in the transcriptome and epigenome, with increased DNA methylation and loss of a repressive histone mark. Thousands of genes showed differential expression, with a significant portion potentially being regulated by epigenetic mechanisms. Down-regulation of genes related to fruit ripening and softening was consistent with the prolonged shelf-life. Large-scale epigenome reprogramming during post-harvest likely contributes to delayed fruit senescence.

Summary: Research has found that the expression and mobilization of retrotransposons are increased in a Drosophila melanogaster model of Huntington's disease. By inhibiting the mobilization of retrotransposons, the neurodegeneration and genome instability in larval brains can be rescued, and the lifespan of flies is increased. These results suggest that the activation of retrotransposons may be involved in polyQ-induced neurotoxicity and could be a potential pharmacological target.

Summary: Transposable elements (TEs), also known as jumping genes, are repetitive sequences with the capability of changing their location within the genome. This study shows that intron retention (IR) can impact TEs quantification using established tools with default parameters in RNA-seq analysis. Reads mapped on intronic TEs were associated with the expression of TEs and influence their correct quantification as independent transcriptional units. These findings are important for achieving accurate quantification of TEs expression in RNA-seq data, especially in samples with abundant IR.

Summary: Numerous recent studies have shown that many aquatic animals ingest microplastics, but the reason why fish mistakenly feed on plastics remains unclear. This study found that biofilm on the surfaces of microplastics in the water environment may contribute to fish misfeeding. The results showed that the absorbance of microplastics increased exponentially with the formation of biofilm, and the probability and duration of capture by fish also significantly increased over time. This suggests that drifting microplastics in water may cause fish to mistake them for edible prey.

Summary: The metabolic rate of organisms in deep-sea environments is influenced by both intrinsic and extrinsic factors. We studied the impact of food and temperature on the metabolic rate of the deep-sea isopod, Bathynomus doederleini, and found positive correlations between meal size and specific dynamic action parameters. We also discovered that a 10°C increase in temperature could lead to a 2.4-fold increase in resting metabolic rate.
