Summary: Stipa grandis steppe, as a main community type of temperate grasslands in Northern China, is crucial for livestock production and ecological security. This study investigates the relationships among plant traits, diversity, and ecosystem functions in Stipa grandis steppe during restoration stages through field experiments in Inner Mongolia, China. The results reveal that enclosure effectively promotes plant organic carbon storage, diversity, and soil carbon storage in Stipa grandis community. Additionally, the trade-offs and critical stages for plant diversity and soil organic carbon storage are identified. These findings provide scientific basis for promoting grassland sustainability and restoration in similar areas.

Summary: This study provides a comprehensive evaluation of taxonomic, functional, and phylogenetic diversity of rodents along elevational gradients on a global scale. It reveals that the decoupling of functional and phylogenetic diversity from species richness is particularly pronounced in arid regions. Wet-mountain lowlands and arid-mountain highlands harbor the most functionally and phylogenetically diverse rodent communities.

Summary: By comparing genetic variation of plant species in different altitudinal zones, it was found that high mountain regions exhibit different patterns of genetic differentiation compared to non-alpine zones. Genetic differentiation was significantly higher among populations of species from the alpine zone, while genetic diversity was significantly lower within populations from the alpine zone.

Summary: In this study, we used RADseq data to investigate the genetic diversity, structure, differentiation, and local adaptation of Stipa breviflora. We found low genetic diversity within populations and identified four genetic clusters along its distribution. The results showed that both geographic distance and environmental factors contributed to population differentiation. Through outlier and environmental association analysis, we identified 113 candidate loci as putatively adaptive loci. Additionally, the effects of climatic factors, especially precipitation, on genetic differentiation and local adaptation were explored.

Summary: This study evaluated the genetic structure of 85 sideoats grama populations in Mexico and modeled the environmental niche of genetic clusters of this species over time. The genetic analysis revealed two genetically different clusters with different environmental niches at present time, which necessitate the use of local germplasm from each environmental niche for selection and restoration programs. Furthermore, the study highlighted the importance of considering climate change for genotypes selection and restoration programs as the environmental niche of genetic clusters will change in the future.

Summary: This study evaluated the relative importance of water and energy on dryland plant diversity in China, finding that water availability and interaction with energy were pivotal factors. While water limitation was predominant across the aridity gradient, energy had significant effects in mesic regions. Different plant lifeforms showed varying responses to water and energy along the aridity gradient.

Summary: This study examined the relationship between genetic variation and geographical/environmental gradients in endemic Lilium pomponium in the southern Alps. The results showed that genetic diversity does not decrease towards the geographical periphery, potentially due to a decrease in habitat availability among peripheral populations. Environmental factors may play a significant role in shaping genetic variation and differentiation in populations across different geographic ranges.

Summary: Heavy grazing significantly reduces the growth of Stipa grandis. Transcriptomic, proteomic, and metabolic analyses were conducted to study the plant responses to heavy grazing. The results revealed that pathways involved in flavone and flavonol biosynthesis, tryptophan metabolism, and phenylpropanoid biosynthesis played important roles in regulating the growth and stress adaptions of S. grandis.

Summary: The biodiversity of carrot is important for human diet as it provides useful and necessary components. Eight carrot genotypes with different root colors were distinguished using amplified fragment length polymorphism (AFLP) markers. Three sets of primer pairs produced 92 loci, including 60 polymorphic ones. The genetic distances between the genotypes were calculated using Nei's coefficient. The AFLP method can be used for genetic diversity assessment in carrot breeding accessions with slight modifications including gel staining.

Summary: Sweet cherry germplasm exhibits high phenotypic variation, which may be a result of genetic or epigenetic diversity. The genetic diversity was found to be greater than epigenetic diversity, and epigenetic diversity was shown to have a stronger impact on phenotypic traits in predefined populations of sweet cherry than genetic diversity.

Summary: Intense land use and river regulations have led to the destruction of wetland habitats, affecting plant species like Stratiotes aloides. Maintaining genetic diversity is crucial for species survival. Research found low genetic diversity within populations of Stratiotes aloides, but differences between populations were observed, with distinct genetic groups following major river systems.

Summary: The study found that high frequency extreme precipitation events can enhance plant productivity and nitrogen acquisition by reducing the proportion of nitrogen forms available for plants and soil microorganisms in temperate grasslands. This shift in precipitation frequency creates optimal conditions for ecosystem functions in response to extreme climate events.

Summary: Understanding the relationship between species richness and genetic diversity is a continuous challenge. This study uses avian functional traits and genetic sequences to investigate whether increasing species richness affects morphological space occupation or decreases genetic diversity. The results suggest that higher species richness does not necessarily lead to morphological space occupation or reduced genetic diversity.

Summary: This study aimed to evaluate the effects of different LAB strains on silage quality and bacterial community of Stipa grandis. The results showed that the addition of LAB improved pH reduction and increased water-soluble carbohydrate content. At the genus level, the abundance of Pediococcus and Lactiplantibacillus increased significantly. The findings indicated that the addition of LAB reconstructed microbiota and influenced silage quality.

Among them, five compounds have never been found in the Asparagus genus before. Additionally, the results highlight the close evolutionary relationship among A. lycopodineus, A. cochinchinensis, and A. filicinus.
