“…These findings are partly explained by the fact that the cover and biomass of sedges and grasses were highest in the undisturbed meadows ( Liu et al., 2022 ). Therefore, the coupled effects of the strong competition of maternal plants and the persistent renewing capacity of buds could be regarded as a virtuous cycle in maintaining a higher diversity of buds and dominating species ( Li et al., 2022 ).…”

Bud banks are considered a crucial factor in regulating the species composition of grassland communities and maintaining the ecological function of alpine grasslands. However, few studies have paid attention to the dynamic changes of bud banks from undisturbed to severely degraded alpine meadows. Therefore, this study examined the correlations between plant diversity and bud bank traits at different stages of alpine meadows degradation. Grass biomasses and plant diversity were found to be highest in moderately degraded meadows, and sedge biomasses were highest in lightly degraded meadows. Lack of disturbance and moderate disturbance by herbivores increased the bud bank density of alpine meadows. Consistent with the changes in bud bank density, bud bank diversity was highest in undisturbed meadows. The structural equation model indicated that the densities of rhizome and the densities and diversities of tiller buds play crucial roles in facilitating the greater diversity of the plant community. Our findings suggest that the diversities and densities of rhizome and tiller buds in the degradation stages are synchronized with changes in plant diversity, and in the regenerative ability of bud banks, which largely determine the outcome of restoration in degraded meadows. These findings could provide a frame of reference for effectively restoring degraded alpine regions by regenerating bud banks. The potential driving force and renewal capacity of bud banks should be taken into account in restoring the Qinghai-Tibet Plateau’s degraded meadow.

“…The mud cracks filled with fine sediment particles exhibited multiple linear crack scars on the tidal flat surfaces (Figure 1B). The Chongming Dongtan saltmarsh exhibited continuous sedimentation from April to October, and the accumulated accretion exceeded 20 cm (Li and Yang, 2007). Therefore, the geomorphology of tidal flats changed gradually, which facilitated seed burial.…”

Saltmarshes are valued as key buffering ecosystems against global climate change and sea level rise. However, the knowledge deficit regarding links between colonization of saltmarsh fringes by plants and mud cracking in the lateral dimension considerably limits our understanding of marsh resilience. Here, the role of mud cracks in colonization by saltmarsh plants was investigated. A combination of field experiments, remote sensing, and experimental results revealed that: (1) potential mud cracking zones were formed at the seaward edge of saltmarshes under the influence of tide-induced wetting–drying cycles, where mud cracks were extensively distributed and colonized by new seedlings. (2) The seedling density in the mud cracks was higher than that in the patches, and seedlings in the mud cracks sprouted earlier than those in the patches. The results implied that mud cracking enhanced colonization by saltmarsh plants, rather than being a water stressor. (3) The two main ecological functions of mud cracks in saltmarsh colonization were acting as “seed traps” and “seedling growth promoters.” (4) Mud cracking could be a key factor influencing saltmarsh resilience, especially by promoting the colonization and dispersal of saltmarsh plants. Rapid colonization of potential zones with mud cracks could occur as soon as seeds are available. Our results could facilitate the development of appropriate saltmarsh rehabilitation strategies.

“…The utilization and regulation of water by terrestrial plants have always been the core focus of ecohydrology research (Li et al, 2022;Wang et al, 2021a). Plant water source refers to the water required for plants to maintain normal growth and physiological activities, and affects the distribution of plant populations; it usually includes rainfall, condensation, soil water, surface water and groundwater (Ehleringer and Dawson, 1992;Nie et al, 2011;Song et al, 2016).…”

Research on the ecohydrological processes of terrestrial plants is a frontier field comprising ecology, hydrology and global change research, yielding the key theoretical foundations of ecohydrology. The basic characteristics of the inorganic environment in a karst ecosystem are a lack of water, a lower amount of soil and high amounts of calcium. Vegetation growing in karst areas has certain particularities and a greater degree of complexity compared with other ecosystems. To comprehensively and intuitively understand the current progress and development trends in plant water use research focusing on karst areas, this paper uses the VOSviewer software to analyze the literature on plant water use in karst areas between 1984 and 2022. The results show that: (1) Research on plant water use in karsts has developed rapidly worldwide, and the number of relevant studies in the literature has increased year by year, which together means that it is attracting more and more attention. (2) Research on plant water sources, the geological background of karst areas, seasonal arid tropical climates, the relationship between δ13C values and plant water use efficiency, karst plant water use in karst savannas and subtropical areas, and ecosystems under climate change yields the knowledge base in this field. (3) Most studies in this area focus on the division of water sources of plants in karst areas, the methods of studying the water use sources of plants, and the water use strategies and efficiency of plants. (4) The functional response of plant water use in karst areas to the influence of the Earth's critical zones, the impact of climate change on plant water use in karst areas, the phenomenon of ecohydrological separation in karst areas, and explorations at the community scale and in the spatial dimension will be the focus of future research. These studies will provide key scientific basis for guiding ecological restoration in karst areas and promoting regional sustainable development and are important research directions in the future.
