Within the context of global warming, understanding molecular mechanisms behind physiological plasticity and local adaptation is essential for insect populations. This study performed an integrated miRNA mRNA analysis on Aquatica leii larvae exposed to temperatures 20 °C, 24 28 32 °C. Under varying thermal conditions, 1983 genes exhibited differential expression (i.e., DEGs). These showed significant enrichment in Kyoto Encyclopedia Genes Genomes (KEGG) pathways related carbohydrate metabolism, glycan biosynthesis metabolism. Notably, we detected that “neuroactive ligand–receptor interaction” signaling pathway, which involved environmental information processing, was significantly upregulated °C treatment groups. indicates starting at A. needs maintain normal cellular functions by regulating binding signal transduction. Furthermore, 220 differentially expressed miRNAs (DEMs) were under different temperature conditions. An interaction network constructed between key DEMs DEGs, revealing 12 DEM-DEG regulatory pairs treatments. We found three miRNA-mRNA candidate modules could be leii’s response high temperature, including ggo-miR-1260b ptr-miR-1260b/RN001_010114, CM069438.1_43851/RN001_014852, CM069438.1_43851/RN001_014877. Our data provide deeper insights into responses levels.

Aquatic ecosystems face significant impacts from human-related stressors, demanding a deep understanding of their dynamics and interactions for effective management restoration. The Albufera Lake (Valencia, Spain) presents complex scenario multiple interacting stressors affecting its eutrophic status. In this study, we compiled 50-year dataset used Generalized Additive Models (GAMs) to analyse the main ecological status Lake. Then, assessed individual combined effects on eutrophication using chlorophyll-a concentration as proxy provided recommendations enhance water quality. Overall, found decrease in annual inflow clear effect rice cultivation seasonal patterns Lake's residence time. Our analysis also shows an increase average temperature 2 °C last 50 years, frequency severity heat waves. contrast, slightly negative long-term trend conductivity, despite occurrence peaks summer. Regarding nutrients, identified reduction total phosphorus (from 1.08 mg/L 1987 0.20 2022), while nitrate concentrations have been rather stable. results point at toxic pressure exerted by organic inorganic contaminants during with toxicity occurring field drainage periods. levels were be temperature, scarcity, well between conductivity nitrate, phosphorus. We that stressor are highly dynamic result synergistic antagonistic vary according different levels. Finally, our GAM framework points two potential scenarios: increasing freshwater inflows or deregulating hydrology allow seawater exchange, which key improving short-term.
