“…This reflected that woody and herbaceous species have different ecological strategies to cope with changing environments, especially fluctuating and seasonally inhospitable climates ( Zanne et al, 2014 ; Qian et al, 2017 ). Compared with herbaceous plants, woody plants generally with larger plant sizes and higher investment in tissue construction and maintenance (e.g., higher LDMC) expose in climate, which can facilitate adaptation to unfavorable environments ( Ricklefs and Latham, 1992 ; Wang et al, 2020 ; Zhou et al, 2020 ). Further studies that explore which leaf traits strongly respond to climate conditions for different plant growth forms could improve our understanding of the effects of climate changes on ecosystem functions.…”

Leaf traits play key roles in plant resource acquisition and ecosystem processes; however, whether the effects of environment and phylogeny on leaf traits differ between herbaceous and woody species remains unclear. To address this, in this study, we collected data for five key leaf traits from 1,819 angiosperm species across 530 sites in China. The leaf traits included specific leaf area, leaf dry matter content, leaf area, leaf N concentration, and leaf P concentration, all of which are closely related to trade-offs between resource uptake and leaf construction. We quantified the relative contributions of environment variables and phylogeny to leaf trait variation for all species, as well as for herbaceous and woody species separately. We found that environmental factors explained most of the variation (44.4–65.5%) in leaf traits (compared with 3.9–23.3% for phylogeny). Climate variability and seasonality variables, in particular, mean temperature of the warmest and coldest seasons of a year (MTWM/MTWQ and MTCM/MTCQ) and mean precipitation in the wettest and driest seasons of a year (MPWM/MPWQ and MPDM/MPDQ), were more important drivers of leaf trait variation than mean annual temperature (MAT) and mean annual precipitation (MAP). Furthermore, the responses of leaf traits to environment variables and phylogeny differed between herbaceous and woody species. Our study demonstrated the different effects of environment variables and phylogeny on leaf traits among different plant growth forms, which is expected to advance the understanding of plant adaptive strategies and trait evolution under different environmental conditions.

“…Therefore, herbaceous plants have easier access to soil nutrients in the riparian zone than woody plants, thus benefiting their survival and development [ 46 ]. Other studies have shown that the soil nutrient content and tolerance of herbaceous plants were higher than those of woody plants under the stress of flooding or increased rainfall [ 47 , 48 , 49 , 50 ]. Yet, the three enzyme activities were highest in T2 ( Figure 3 ), which might be attributed to the temperature that affected soil enzyme activities [ 51 ], because the soil temperature was significantly different from T1 and T2 ( Table 1 ).…”

Plant and microbiome interactions are necessary for plant nutrient acquisition. However, relatively little is known about the responses of roots, bulk, and rhizosphere soil microbial communities in different artificial vegetation types (woody and herbaceous) in riparian areas of massive dams and reservoirs. Therefore, this study aims to assess such responses at elevations of 165–170 m a.s.l. in the riparian zones of the Three Gorges Dam Reservoir, China. The samples were collected containing the rhizosphere soil, bulk soil, and roots of herbaceous and woody vegetation at different emergence stages in 2018. Then, all the samples were analyzed to quantify the soil properties, bacterial community characteristics, and their interaction in the early and late emergence phases. In different periods, the weight of dominant soil bacteria, including Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi, and Cyanobacteria, was higher, and their composition was different in the rhizosphere, bulk soil, and endophytes. Moreover, the soil co-occurrence networks indicated that the weight of soil physical properties was higher than chemical properties in the early emergence stage. In contrast, the weight of chemical properties was relatively higher in the late emergence stage. Furthermore, the richness and diversity of the bacterial community were mainly affected by soil organic matter. This study suggests that these herbaceous and woody vegetation are suitable for planting in reservoir areas affected by hydrology and human disturbance in light of soil nutrients and soil microbial communities, respectively. Additionally, these results provide valuable information to inoculate the soil with key microbiota members by applying fertilizers, potentially improving plant health and soil production.

“…These were: mean annual temperature (MAT), mean annual precipitation (MAP), temperature seasonality (TSN, the coefficient of variation of mean monthly temperature), precipitation seasonality (PSN, the coefficient of variation of mean monthly precipitation). These variables have been used in previous studies on sexual systems (Wang et al, 2020a).…”

“…Species with different sexual systems often vary in their morphological (Renner & Ricklefs, 1995), physiological (Etterson & Mazer, 2016; Tognetti, 2012), life‐history (Moeller et al, 2017) and reproductive traits (Lebel‐Hardenack & Grant, 1997; Pannell, 2017). Life‐history trade‐offs may have contributed to sex expression instability (Charlesworth, 1999; Korpelainen, 1998), and the differential establishment and success of alternative sexual systems in response to different ecological, geographical and climatic settings (Fox, 1985; Wang et al, 2020a,b). Therefore, sexual systems are frequently considered as a key factor underpinning the evolution of angiosperm diversity (Barrett, 2002; Sabath et al, 2016).…”

“…The drivers of the geographical variation in sexual system prevalence also remain poorly understood. It has been suggested that growth form and climate (especially precipitation and temperature) may be determinants of this variation (Etterson & Mazer, 2016; Moeller et al, 2017; Wang et al, 2020a). Both ecological and phylogenetic studies indicate that dioecy is widely associated with woody growth forms, whilst hermaphroditism is associated with herbaceous growth forms (Moeller et al, 2017; Vamosi et al, 2003).…”

Angiosperm sexual systems are fundamental to the evolution and distribution of plant diversity, yet spatiotemporal patterns in angiosperm sexual systems and their drivers remain poorly known. Using data on sexual systems and distributions of 68453 angiosperm species, we present the first global maps of sexual system frequencies and evaluate sexual system evolution during the Cenozoic. Frequencies of dioecy and monoecy increase with latitude, while hermaphrodites are more frequent in warm and arid regions. Transitions to dioecy from other states were higher than to hermaphroditism, but transitions away from dioecy increased since the Cenozoic, suggesting that dioecy is not an evolutionary end point. Transitions between hermaphroditism and dioecy increased, while transitions to monoecy decreased with paleo‐temperature when paleo‐temperature >0℃. Our study demonstrates the biogeography of angiosperm sexual systems from a macroecological perspective, and enhances our understanding of plant diversity patterns and their response to climate change.
