“…In this study, elevation and slope were both positively correlated with community stability ( p < .05). Previous studies have demonstrated that elevation was a key topographic factor that significantly impacted species distribution and forest stability (Fu et al, 2019 ; Wang et al, 2017 ), while slope may indirectly affect vegetation stability by affecting species composition and diversity (Belote, 2018 ). Furthermore, areas with higher elevation or steeper slope are less accessible for humans or large animals, therefore are less disturbed (Belote, 2018 ; Nüchel et al, 2019 ), which may, improve the temporal stability of community productivity.…”

The stability of forest productivity can reflect the functioning of forest ecosystems. It is a crucial topic to understand the relationship between biodiversity and ecosystem functions in ecology. Although previous studies have made great progress in understanding the effects of diversity, species asynchrony, and other factors on community biomass and productivity, few studies have explored how these factors affect the temporal stability of productivity. In this study, we hypothesized that diversity, species asynchrony, and topography would directly or indirectly impact the temporal stability of productivity. To test this hypothesis, we used a multiple regression model and a piecewise structural equation model based on the inventory data over 20 years (5‐year intervals) from 1992 to 2012 at Jingouling Forest Farm in Northeast China. Our results showed that species asynchrony was the main driving factor affecting the temporal stability of productivity. Structural diversity significantly decreased community stability, while species diversity had a nonsignificant effect on it. We found the combination of a multiple regression model and a piecewise structural equation model is an effective method for evaluating the factors that influence community stability. The effect of species asynchrony is crucial for understanding the ecological mechanisms underlying the diversity–stability relationship in mixed forests.

“…From this perspective, biodiversity-phenology relationships, understudied in real-world landscapes ( 22 ), could help reduce uncertainties in models of ecosystem function that still fall short in capturing seasonality ( 50 ). These questions, again, argue for more rigorous analyses comparing remotely sensed phenology with field measurements of functional and phylogenetic diversity, which have been particularly scarce in wetlands ( 32 , 45 ).…”

“…Climate covariates were included to adjust for climate-induced variability in phenological timing of changes in greenness ( 12 , 15 , 18 , 45 , 55 ) using gridded datasets (table S2) for daily mean atmospheric temperature and daily precipitation over 2002–2019, accessed via Google Earth Engine. For each site, atmospheric temperature was summarized for 2002–2019 as mean and SD of its annual mean value (MeanMeanTemp and StdevMeanTemp, respectively), while precipitation was summarized as 2002–2019 mean and SD of its annual sum (MeanSumPrecip and StdevSumPrecip, respectively).…”

“…Given common zonation of vegetation species and traits along wetland inundation gradients (33,45), mechanisms behind the links between diversity and phenological variability could include seasonal asynchrony and diversity of responses to flooding, climatic variation, and disturbance (4), facilitating complementary utilization of space and resources. However, this assertion requires further research, as earlier studies do not reach a consensus on diversity-complementary relationships, finding them relevant mainly at lower species richness levels (46)(47)(48).…”

Plant diversity reduces satellite-observed phenological variability in wetlands at a national scale

Plant diversity may enhance stability of ecosystem function and its satellite-derived indicators. However, its potential to stabilize phenology, or seasonal changes in plant function, is little understood, especially in understudied systems with high biodiversity potential such as wetlands. Using a large sample of U.S. wetlands and a new satellite-based indicator of phenological stability, we found that plant diversity was negatively associated with interannual phenological variability after controlling for covariates representing climate, site conditions, and spectral fluctuations. Furthermore, plant diversity and covariates better explained phenological variability than stability in annually summarized satellite-based biomass indicators used by earlier studies. Last, a subsequent path analysis indicated that phenological variability could mediate plant diversity relationship with the latter stability. Our results suggest that contributions of plant diversity to seasonality of ecosystems may have a stabilizing role in their functioning and offer a new basis for assessing biodiversity-stability relationships across broad geographic extents.

“…In freshwater lakes, submerged macrophytes are an important trophic level and play a vital role in determining ecosystem stability and services (Fu, Yuan, Jeppesen, Ge, Zou, et al., 2019; Fu et al., 2015, 2018; Scheffer et al., 1993). Thus, understanding the beta diversity patterns, including the turnover and nestedness components, of submerged macrophytes at different scales is essential.…”
