To maintain the dynamic equilibrium in elemental contents, zoo-benthos must get a balance with their resource supply or alter their stoichiometric characteristics in response to environmental changes. We investigated the ecological stoichiometric characteristics of six macrozoobenthos species, including bivalve (<i>Moerella jedoensis, Nitidotellina minuta, Mizuhopecten yessoensis</i>) and ophiuroidea (<i>Amphioplus japonicus, Ophiura sarsii vadicola, Ophiopholis mirabilis</i>), which were collected from the coastal waters of Dalian Island in the northern Yellow Sea in May and August 2020. Results showed that the range of C, N, and P contents in the six species was 23.4%-49.8%, 4.3%-14.7%, and 0.1%-1.1%, respectively. The range for C:N, C:P, and N:P was 3.12-6.75, 29.01-410.63, and 6.32-113.9, respectively. The P content exhibited a relatively larger range of variation than C and N, leading to higher variability in C:P and N:P. There were significant differences in element contents and ratios between the two groups, bivalve and ophiuroidea. The stoichiometric characteristics of the three shellfish species under bivalve was significantly different in N content, C:N and N:P, while the three ophiuroidea species had significant differences except for C content, indicating that the ecological stoichiometric characteristics of marine macrozoobenthos had interspecific differences. The ecological stoichiometric characteristics of the same group and species were not significantly different between the two months.

Following the framework of ecological-living-production space, we analyzed the dynamics and driving factors of the coupling transformation of the ecological-living-production system in 26 mountainous counties from 2010 to 2021, based on coupling coordination model, kernel density estimation, spatial Markov chain model and optimal parameter geodetector model. The results showed that, the coupling coordination degree of the green transformation of the ecological-living-production system had significantly increased, and the gap among counties had shown an evolutionary trend of stepwise narrowing. In 2016, there was a polarization phenomenon. The coupling coordination degree of the green transformation of the ecological-living-production system presented a spatial pattern of \"high in the east and low in the west, high in the north and low in the south\". The spatial directivity characteristics were gradually obvious, while the spatial structure evolution showed the characteristics of collaborative response. There was an obvious \"club convergence\" phenomenon in the coordinated transformation of the ecological-living-production, and each convergence club had strong stability. It was difficult for the coupling coordination type to achieve leap-forward transfer in adjacent years, and there were still \"path dependence\" and self-enhancement \"lock-in effect\". The spatial lag factor had a greater influence on the type of coupling coordination. The counties with higher coupling coordination degree had a greater probability of driving the neighboring counties to move upward, whereas the counties with low coupling coordination degree may inhibit the improvement of the coupling coordination degree of the surrounding counties. The coordinated transformation of the ecological-living-production system in 2010, 2015, and 2021 was driven by the progress of social civilization, opening up and economic development, economic development and scientific and technological development, respectively.

We subjected two-year-old <i>Pinus tabuliformis</i> seedlings to a long-term drought stress period of 20 months, followed by a high-intensity drought treatment (continuous 80 days with 100% rainfall reduction). Additionally, we administered re-irrigation treatments lasting 10 days on days 10, 40, 70, and 80 of the high-intensity drought period. We aimed to investigate the relationships among hydraulic conductivity, percentage loss of hydraulic conductivity, and the content of osmotic adjustment substances in new branches of <i>P</i>. <i>tabuliformis</i>, as well as their responses to drought. The results showed that under long-term drought stress, the water potential threshold at which hydraulic conductivity loss reached 50% for new branches under mild stress was -2.04 MPa, which was significantly lower than that of the other treatments. After 80 days of high-intensity drought, the proline content in new branches increased significantly by 19.9% to 226.0% compared to the initial value. Redundancy analysis showed that proline explained 40.4% of the variability in hydraulic function and was the primary osmotic adjustment substance during high-intensity drought. During re-irrigation, soluble sugars explained 29.4% of the variability in hydraulic function and were the main osmotic adjustment substances in this stage. Different factors accounted for the differences in hydraulic function of <i>P</i>. <i>tabuliformis</i> during drought and re-irrigation.

We measured the concentration and stoichiometry of carbon (C), nitrogen (N), and phosphorus (P) in leaves, branches, and soils at different layers. We analyzed the relationship between leaf, branch nutrient characteristics and soil physicochemical properties. The results showed that soil C and N contents decreased after an initial increase with increasing stand ages, being the maximum at the 39 years old stand, while P content was the maximum at 47 years old stand.
