The final structural equation model relating nitrogen (N) addition, drought, species asynchrony, leaf area of dominant species, dominant species productivity stability (DSPS) and dominant species compositional stability (DSCS) to grassland community compositional and productivity stability under scenarios of (a) intense drought (ID), (c) chronic drought (CD), and (e) reduced precipitation frequency (RF).
#IntenseDrought and #ChronicDrought both reduced the #ProductivityStability without altering #CompositionalStability of the typical steppe, while reduced precipitation frequency had the opposite effect.

Relationships between the stability of plant community ANPP and mean species richness (a), species asynchrony (b), population stability (c) and dominant species stability (d) across control (Cont) and N addition treatments with different IN:ON ratios.
📖 Different inorganic to organic nitrogen ratios (IN:ON) ➡️ Ecosystem stability 🟰 Effects❓
Results:
1️⃣ IN:ON ratio showed no significant effect on community stability.
2️⃣ IN decreased species richness more than ON.

Effects of nitrogen (N) deposition in homogeneous and heterogeneous phosphorus (P) distribution environment on the relative abundance of specific organic acids composition (a). (b–e) All volcano plots that illustrate the significant differences and abundance changes of each organic acid. (a) Specific organic acids are represented by different colors for easy of identification. (b–e) The horizontal axis represents the log-fold changes in the relative abundance of organic acids, while the vertical axis indicates the significance level, expressed as a log-transformed P-value.
🌳 #NitrogenDeposition ➕ phosphorus distribution patterns ➡️ root adaptation
Results:
1️⃣ N deposition restructures root foraging strategies along a “morphological-enzymatic” axis;
2️⃣ P-efficient clones exploit spatial nutrient heterogeneity through root proliferation.

Top: The distribution of sites from the PREDICTS database and the level of total N deposition. The size of the point represents the number of sites per study (Nsites). The change from blue to orange indicates the increase in the total amount of atmospheric N deposition. N deposition values were loge-transformed, with N deposition ranging from 0.8 mg N m−2 yr−1 to 7960.0 mg N m−2 yr−1. Bottom: The response of arthropod species richness (bottom left) and total abundance (bottom right) to the interaction of N deposition and land use. Likelihood ratio test of the interactive effect of N deposition and land use: species richness = 35.62, p < 0.001; total abundance = 30.68, p < 0.001. Values represent the percentage difference compared with Primary vegetation sites with the 2.5th percentile value of total N deposition. The lines with different colors represent the median predicted value for each land-use type, with shaded areas representing the 95% confidence intervals. The results are predicted across 95% of the range of N deposition values for each land-use type.
