ABSTRACT The sediments in mangrove forests play an important role the global carbon cycle due to high inputs of organic matter (OM) and low decomposition rates, making them highly efficient at sequestering carbon. balance between OM sequestration these systems is influenced by a complex interplay environmental factors. However, there large amount uncertainty surrounding rates from forests, particularly regional scales. We used standardized assays labile recalcitrant substrate 30 estuaries, spanning gradient human land use intensity, identify dominant drivers temperate forests. Our results reveal that, while strongly driven eutrophication, primarily increases minimum sediment temperature. Furthermore, we demonstrate that nutrient enrichment use, combination with increased temperature, synergistically accelerates OM, thereby threatening potential ecosystems. This suggests coastal eutrophication can exacerbate effects warming on decomposition, leading heightened vulnerability storage feedbacks local stressors.

Difenoconazole and imidacloprid are key components of seed-coating agents, which alter soil microbial community structure function after application. Existing studies mainly focus on the environmental effects their spraying application, while research impacts ecosystem when used as agents is relatively limited. Through field experiments, this study systematically evaluated compared difenoconazole seed coatings wheat rhizosphere communities ecological functions by measuring enzyme activities, employing 16S rRNA ITS high-throughput sequencing technologies predicting KEGG functional pathways. The results showed that significantly reduced bacterial diversity, particularly under high-dosage treatment (0.18 g a.i./kg seed), with a 5.80% decrease in diversity day 30. This most strongly inhibited phyla Bacteroidota Myxococcota, maximum reductions 23.87% 63.57%, respectively. However, abundance Actinobacteriota increased, increase 38.53%. Additionally, fungal increased both treatments. Both altered from days 20 to 60, recovery occurring 120. Furthermore, pathway analysis revealed seed) activated pathways such cell motility, signal transduction, membrane transport, whereas standard dosage (0.12 exhibited metabolic suppression. elucidates dynamic agent application communities, providing theoretical support for rational pesticide use optimization agricultural strategies.
