“…Litter removal indirectly and significantly stimulated species richness by increasing PAR in our SEM, because increased PAR stimulates species richness by stimulating photosynthesis in most species (Craine & Dybzinski, ; Davis et al, ), despite some other studies reporting that radiation has no effect on species richness (Dorji, Moe, Klein, & Totland, ; Zhou et al, ). However, the decrease of SM and the increase of PAR indirectly inhibited species richness by inhibiting seedling recruitment rather than directly affecting species richness in the litter removal plots.…”

Plant community diversity is conducive to maintain the regional ecosystems stability and ecosystem services. Seed germination is one of the main ways to regulate plant diversity, owing to seedling recruitment as a basis for plant community renewal. However, the exact mechanism of how plant litter affects seedling recruitment, and species richness is not yet fully understood. Therefore, a litter addition and removal experiment was established in a semiarid grassland to study the effects of plant litter on seedling recruitment and species richness from April to August in 2016 and 2017 in Northern China. The positive correlation between species richness and seedling recruitment indicated that a guarantee of seedling recruitment was the main precondition to protect species richness. Adding rather than removing litter significantly reduced species richness. Litter addition inhibited species richness by directly increasing mechanical damage or indirectly reducing photosynthetically active radiation and seedling recruitment. The results of this study are conducive to understand the evolutionary and regulatory mechanisms of community species richness and seedling recruitment in grassland ecosystems after adding or removing plant litter.

“…Plant diversity is mediated at different stages of plant growth, including seed germination, seedling growth, age of senescence, and offspring performance. Most studies focus on the responses of mature or offspring plant species diversity to N deposition (Bobbink et al, 2010;Hu & Wan, 2019;Liu et al, 2019;Xia & Wan, 2013;Zhou et al, 2019). It is also necessary to study how natural seed germination directly responds to N deposition.…”

Seed germination plays an important role in mediating plant species composition of grassland communities under nitrogen (N) enrichment. Shifts of plant community structure with N‐enhanced deposition in terrestrial ecosystems have occurred globally. Despite numerous studies about the effects of enhanced N deposition on mature plant communities, few studies have focused on seed germination. Using a laboratory experiment, we report the effects of five N concentrations, including 0, 5, 10, 20, and 40 mM N (NH4NO3) on seed germination of eight semi‐arid grassland species. Results showed that low N concentrations (5‐ and 20‐mM N) promoted mean final germination proportion of all eight species by 4.4% and 6.4%, but high concentrations (40 mM N) had no effect. The mean germination rate was decreased 2.1% and 5.1% by higher N concentration (20‐ and 40‐mM N) levels, but germination start time showed the opposite trend, delayed by 0.7, 0.9, and 1.8 d for the 10, 20, and 40 mM N treatments. Final germination proportion, mean germination rate, and germination start time were significantly different among species in response to N concentration treatments. The final germination proportion of Allium tenuissimum and Chenopodium glaucum were suppressed by increased N concentration, whereas it increased for Potentilla bifurca, Plantago asiatica, and Setaria viridis. Our findings provide novel insights into N deposition‐induced species loss based on seed germination factors in semi‐arid grassland communities.

“…For this reason, the strategies and technologies of natural forest restoration have received increased attention in recent years. The transplantation of propagules from similar forests to reestablish or restore forms of vegetation in a destroyed, damaged, or degraded system is a popular approach in ecological practices [3][4][5][6], but the low community similarity between the restored vegetation and the reference forest limits its utilization. The succession process and biological characteristics that are involved indicate that seedling survival, individual growth, and community dynamics are strongly affected by physical environment factors, and light is one of the most important determinants [7][8][9].…”

Shading Gradients Drive Differential Responses of Leaf Traits in an Early Community Germinated by Forest Topsoil

et al. 2022

Seedling performance in the early stage is crucial to natural forest restoration, and functional traits have been widely employed in exploring plant adaptation under field conditions. However, the responses and variabilities of leaf traits have not been clearly defined at the light gradients that are used in restoration practices. We evaluated the variation in leaf treats in species and community levels in a controlled field plot with shading treatments. We found that the variation characteristics differed across different species and trait types along shading gradients. Individuals of most species had a larger leaf area (LA) and specific leaf area (SLA) in the shaded habitats, while only a few tree species showed significant responses in their leaf shape and chlorophyll concentration. Although LA and SLA showed similar directions and trends of changes in the trait mean, four response models were observed based on the light points corresponding to initial responses and following trends. The extent of within-species trait variation for each treatment was similar at the community level due to diverse changes in the direction and degrees of variation in co-occurring species. Intraspecific variation was limited within each shading treatment, while it noticeably contributed to the local adaptation in the entire heterogeneous restoration community. Our findings indicate that species with different trait combinations will have different responses to light gradients, and that the mean and degree of variation in leaf traits will also lead to distinctive strategies being created to match the different shading conditions. Vegetation restoration should consider the adaptive traits and their response diversity when selecting species and for habitat management with specific trait–environment interactions.
