The Yellow River is the key corridor for to disperse from Asia inlands to east seashores.

Plants of the L. genus (Tamaricaceae) mainly occur in arid inlands of Asia, but a few species occur in the coastal areas of China, and the Yellow River may account for this. This study was conducted to elucidate whether and how the Yellow River affects the pattern and development of the genus, involving two critical species of Nakai and Lour.

Species divergence and environmental adaptation of complex at the whole genome level.

To study the interspecific differentiation characteristics of species originating from recent radiation, the genotyping-by-sequencing (GBS) technique was used to explore the kinship, population structure, gene flow, genetic variability, genotype-environment association and selective sweeps of complex with similar phenotypes from a genome-wide perspective. The following results were obtained: 14 populations of complex could be divided into 5 clades; and diverged earlier and were more distantly related to the remaining 6 spruce species. Various geological events have promoted the species differentiation of complex.

Soil nutrient limitation and natural enemies promote the establishment of alien species in native communities.

The invasion of alien plant species threatens the composition and diversity of native communities. However, the invasiveness of alien plants and the resilience of native communities are dependent on the interactions between biotic and abiotic factors, such as natural enemies and nutrient availability. In our study, we simulated the invasion of nine invasive plant species into native plant communities using two levels of nutrient availability and suppression of natural enemies.

Food Nitrogen Footprint Increased by 35% on the Third Pole During 1998-2018.

The N footprint is considered as an indicator of potential environmental damage from N. Quantitative analysis of N footprint distribution, sources and drivers can help mitigate its negative impacts and promote sustainable N management. In this study, we constructed a city-scale food N footprint (FNF) framework for the Qinghai-Tibet Plateau (QTP) using a N mass balance approach.

Genetic diversity and population dynamic of var. (Bunge) Hu ex H. F. Chow in Central China.

Phylogeographic research concerning Central China has been rarely conducted. Population genetic and phylogeography of var. (also called sour jujube) were investigated to improve our understanding of plant phylogeographic patterns in Central China.

Increase in leaf organic acids to enhance adaptability of dominant plant species in karst habitats.

Estimation of leaf nutrient composition of dominant plant species from contrasting habitats (i.e., karst and nonkarst forests) provides an opportunity to understand how plants are adapted to karst habitats from the perspective of leaf traits.

Fine root dynamic characteristics and effect on plantation's carbon sequestration of three shrub plantations in Tibetan Plateau alpine sandy land.

Desertification land in Gonghe Basin of Tibetan Plateau, China accounts for 91.9% of the total land area. Vegetation restoration and reconstruction with desert shrubs in degraded ecosystem are effective ways to prevent and control desertification.

Genetic architecture, demographic history, and genomic differentiation of revealed by whole-genome resequencing.

Forest trees are an excellent resource from which to understand population differentiation and heterogeneous genome variation patterns due to the majority of forest trees being distributed widely and able to adapt to different climates and environments. is among the most geographically widespread and ecologically important tree species in China. Whole-genome resequencing data of 75 individual examples of throughout China were conducted, finding that all examples from different regions were clearly divided into either Northeast (N), Central (C), and South (S) populations.

Belowground biomass of alpine shrublands across the northeast Tibetan Plateau.

Although belowground biomass (BGB) plays an important role in global cycling, the storage of BGB and climatic effects on it are remaining unclear. With data from 49 sites, we aimed to investigate BGB and its climatic controls in alpine shrublands in the Tibetan Plateau. Our study showed that the BGB (both grass-layer and shrub-layer biomass) storage in the alpine shrublands was 67.

Phylogeographic analyses of a widely distributed : Further evidence for the existence of glacial refugia of cool-temperate deciduous trees in northern East Asia.

Despite several phylogeographic studies had provided evidence to support the existence of glacial refugia of cool-temperate deciduous trees in northeast China, the species used in these studies were limited by the species ranges, which could not exclude the possibility that northern populations were the colonists from southern refugial populations during the last glacial maximum (LGM). Here, we estimated the nucleotide variation in , a widespread species distributed in Eurasia. Three groups in northeast, central, and southwest China were constructed according to the simulation results from SAMOVA, composition of chloroplast haplotypes and structure results.
