Summary: Nitrogen addition can alter the reproductive strategy and growth patterns of Leymus chinensis, leading to higher investment in vegetative and clonal organs, and lower investment in sexual organs. The optimal N addition rates for sexual reproduction, vegetative growth, and clonal reproduction were found to be 16 g N m^(-2) and 32 g N m^(-2) respectively.

Summary: This study found that extreme drought during spring has significant impacts on the grassland ecosystem in Northern China. The effects of drought on grassland vegetation growth were examined by conducting a simulated extreme drought experiment on a Leymus chinensis steppe. The results showed that although drought reduced soil moisture and vegetation coverage, it did not significantly decrease the leaf water potential of L. chinensis. Additionally, the vegetation coverage fully recovered at the end of the growing season, indicating a certain degree of resilience to spring drought in degraded grasslands.

Summary: Oedaleus decorus asiaticus is a harmful pest in Inner Mongolia, China that causes serious problems in animal husbandry and agriculture. This study used a UAV with a camera to collect multi-spectral data and analyzed nine vegetation indices to estimate plant loss caused by O. decorus at different growth stages. The results showed that the density and growth stage of O. decorus have a significant impact on plant loss.

Summary: The study demonstrates that increased rainfall amounts with prolonged dry intervals can promote Leymus chinensis biomass production by increasing soil moisture, while prolonged dry intervals with increased precipitation per event may decrease the available soil nitrogen content. Different rainfall patterns can affect the biomass production of Leymus chinensis.

Summary: This study found that the biomass of Leymus chinensis was significantly higher in saline-alkaline grasslands compared to non-saline-alkaline grasslands. Changes in rhizosphere bacterial and arbuscular mycorrhizal fungi (AMF) communities had a greater impact on biomass than climate, soil moisture, nutrients, and salinity. The co-occurrence networks of bacteria and AMF in saline-alkaline grasslands were more complex and connected, promoting plant tolerance and growth under salt-alkali stress.

Summary: The study found that grazing increased bacterial diversity but reduced fungal diversity in plant leaves. Grazing also increased the abundance of Chloroflexi, Gemmatimonadota, Nitrospirota, Sordariales, and Pezizales in plant leaves, and the Bray-Curtis similarities of microbial communities were higher under grazing plots.

Summary: This study investigated the impact of changes in precipitation volume and dry intervals on bacterial co-occurrence networks in grassland ecosystems. The results showed that alterations in precipitation and dry intervals did not significantly affect bacterial diversity, but had a significant effect on the co-occurrence network structure. Prolonged dry intervals were found to reduce the robustness of bacterial networks, and the complexity and stability of the network were primarily influenced by soil water content, phosphorus, and aboveground biomass.

Summary: The study on the effects of grazing exclusion on Leymus chinensis meadows at different restoration stages highlighted the importance of understanding the variations in plant diversity and productivity during restoration processes. The results showed that the relative benefits of grazing exclusion changed over time, from higher benefits for diversity to greater benefits for productivity. The study recommended a 15-year duration of grazing exclusion for maintaining ecosystem structure and function in grasslands.

Summary: Soil salinity is a significant abiotic stress affecting ecosystems worldwide, with Chinese rye grass having distinct ecotypes, namely yellow-green and gray-green, showing different strategies for coping with salt stress. The gray-green ecotype exhibited higher seed germination percentage and shorter germination time, longer radicles, and longer shoot length compared to the yellow-green ecotype under salinity stress. The gray-green ecotype was more salt-tolerant and had higher thousand-grain weight, indicating its potential for saline grassland restoration.

Summary: Competition drives evolutionary change across species, but our understanding of how competitive differences among species direct the evolution of interspecific interactions is incomplete. By studying competition between a grass species and an invasive species, we found that populations can evolve increased competitive ability through reduced interspecific or intraspecific competition. Trade-offs do not always constrain the evolution of competitive ability, and the evolution of one species can influence its opponent's competitive ability.

Summary: Effective utilization of water is crucial for maintaining plant biomass. The study found that nitrogen deposition has a significant impact on water use efficiency and photosynthesis properties of plants. In salinized-alkalized grasslands, increased nitrogen availability can enhance photosynthesis and water use efficiency. These findings are important for predicting the response of grasslands to future nitrogen deposition.

Summary: The study suggests that gossip is a competition strategy to compete for valuable and scarce resources, especially intensifying with more valuable and scarcer resources. Additionally, alliances help deter negative gossip and increase expectations of reputational harm to competitors.

Summary: Ecologists often use species niches to study community composition, assuming linear response or quadratic curves, but there are differences in species' ability to tolerate deviations from their optimal environment, which can affect relationships between species.

Summary: High-value roadsides play an important role in improving landscape permeability. Increasing the ratio of high-value roadsides can enhance both structural and functional connectivity in landscapes with low permeability. In landscapes with high permeability, roadsides only support movement of specialized species. Therefore, land management should focus on the preservation and restoration of semi-natural grasslands.

Summary: In community ecology, unconstrained ordination and constrained ordination are used to explore drivers of community composition indirectly and directly, respectively. However, existing constrained ordination methods do not explicitly account for community composition that cannot be explained by the predictors, potentially leading to misrepresentation. This article proposes and develops new methods that incorporate predictors directly into an ordination, and evaluates their performance against popular methods in community ecology.
