Our results indicate that: (1) the life cycle extraction method achieved a classification accuracy exceeding 80%, and from 2001 to 2022, the overall distribution of early-spring ephemeral plants exhibited an increasing trend; (2) snowend, snowday, and precipitation during the driest quarter were the primary drivers of ephemeral plant distribution, collectively explaining over 60% of the observed variation, and structural equation modeling further revealed that snow and precipitation had significant positive effects on their distribution; and (3) under future climate scenarios, Medium-NDVI areas are projected to expand northward and westward, with the potential emergence of new suitable habitats in northern localities by mid-century.

By analyzing the local and SR at 18 h in both induced and constitutive leaves of the damaged plants, a clear trend in the response to the stimulus was noticed, with the levels of some defense-related metabolites increasing.

Collectively, these results demonstrate a clear trend of enhanced accumulation of these principal sedative constituents with delayed harvest time.
Consistent with the Y(II) pattern, ETR(II) also showed a decreasing trend during the spike coloration process of CPZ, indicating a gradual decline in PSII electron transport capacity ( Figure 4 b).
[ 18 ] examined the temperate coniferous forests of Kalam, Pakistan, and they reported a decreasing trend in the plant carbon storage across functional groups with increasing elevation that peaked within the mid- to low-elevation zones.
As shown in Table 2 , with the increase in nitrogen content, the contents of soil total nitrogen (TN), nitrate nitrogen (NO 3 − -N) and nitrite nitrogen (NO 2 − -N) all showed a trend of first increasing and then decreasing.
It can be seen from Figure 3 that with the increase in soil nitrogen content, the soil urease activity (UE) and neutral protease activity (NPA) in the treatment without biochar addition both showed a decreasing trend.
ranged from 4.66 to 11.87 g per pot, with a decreasing trend as PE application rates increased.
Analysis of variance (ANOVA) confirmed highly significant effects of genotype (Cv), environment (E), and their interaction (Cv × E) for almost all traits studied ( Table 1 ).
A p < 0.05 was considered statistically significant, and p < 0.01 and < 0.001 were considered highly significant.
Concurrently, soluble sugar and soluble protein contents showed an increasing trend under 0.05% PE treatment, with soluble sugar increasing by 41.6% compared with CK.
Two levels of correlation were set, with p < 0.05 indicating a significant correlation and p < 0.01 indicating a highly significant correlation. 4.11.
Furthermore, Table 4 and Table 5 display the overall effect (χ 2 ) of the species variable on the content of the different compound classes, indicating that species had a highly significant effect on all analyzed compound classes as a result of the type II ANOVA.
During fruit development, biochemical quality traits showed an increasing trend, while several bioactive compounds (total phenolic content, antioxidant capacity, and vitamin C) exhibited a decreasing trend towards maturity.

Based on the values of average annual air temperatures and average annual precipitation in the Banja Luka area ( Figure 6 ), recorded over the past 15 years (2010–2024), there is a clear trend of increasing average annual air temperatures since 2010, with the maximum value recorded in 2024 (14.3 °C).
For total chlorophyll, Chl (a + b), statistical analysis revealed no significant differences among groups; however, an increasing trend was observed in the MgSO 4 and Bulk treatments.
Total protein content decreased significantly under the Bulk treatment (by 26%) and showed a decreasing trend in variants with 75–200 mg L −1 MgO-NPs (by 12% and 18%, respectively).
The results indicated a decreasing trend in leaf PTS content under Cd exposure, although the changes were not statistically significant.
In this study, a highly significant positive correlation was observed between REC and MDA content, suggesting that membrane lipid peroxidation may contribute to low-temperature injury.
The Pearson correlation analysis in this study showed positive and highly significant associations between the vegetative variables, highlighting the codependency between LW and LL (r = 0.99), as well as of the PH with the LL (r = 0.94) and the LW (r = 0.94) ( Figure 1 ).

Overall, the comparison between 2023 and 2024 showed a clear trend: in all three mixture types, the proportion of legumes increased markedly, while the share of grasses declined accordingly.
As the growth stage progressed, the rolling rates of the top three leaves of ST-12 showed a decreasing trend, and there was no significant difference between the two nitrogen levels ( Figure 2 C,E). 2.3.2.
In this study, SWC showed an increasing trend with afforestation, which resulted in the highest microbial biomass occurring in L42.
Specifically, low-density stands exhibited a pattern of initially decreasing, then increasing, and finally decreasing again; medium-density stands showed a trend of initially increasing, then decreasing, then increasing again, and finally decreasing; while high-density stands displayed a pattern of initially decreasing, then increasing, and then decreasing again.
NtRD26 was also induced by mannitol, and NtCAPE17 treatment showed a decreasing trend, although the difference compared with mannitol alone was not significant ( Figure 9 D).
