Article
Soil water availability is the critical limitation for soil respiration (Rs) and subsequent ecosystem functions in biological soil crusts (BSCs) of arid ecosystems. Thus, uncovering the response mechanism of Rs to different precipitation regimes will improve our knowledge of the potential impacts of global climate change on this fragile ecosystem....

Aims: When the external environment changes, plants can change their own functional traits and adjust adaptation strategies in a timely manner. Therefore, plant functional traits can effectively reflect the response of plants to the change of grassland use. However, there are few studies on the effects of grassland use patterns from the perspective...
Article
The important role of biological soil crusts (biocrusts) in determining the soil carbon balance in dryland ecosystems under future climate change has been widely explored. However, when assessing the effects of biocrusts on soil respiration, few studies have considered biocrusts in bare soil patches and shrub soil patches. A field experiment was pe...

Plant functional traits reflect species ecological strategies and determine how plants respond to environmental changes, however, how dominant species in the Inner Mongolia grassland adapt to different grazing systems by changing their functional traits has not been systematically investigated. In this study, we established four 7-year grazing trea...

Questions: Species-area relationships (SARs) are fundamental for understanding biodiversity patterns and are generally well described by a power law with a constant exponent z. However, z-values sometimes vary across spatial scales. We asked whether there is a general scale dependence of z-values at fine spatial grains and which potential drivers i...
Data
Conceptual figure summarizing our hypotheses how different drivers could influence fine-grain β-diversity via changing mean occupancy of species, based on the findings of our study and theoretical considerations. Fine-grain β-diversity (and likewise for larger grain sizes) is mathematically linked to mean occupancy, which can be decomposed into (i)...

Accurate monitoring of grassland vegetation dynamics is essential for ecosystem restoration and the implementation of integrated management policies. A lack of information on vegetation changes in the Wulagai River Basin restricts regional development. Therefore, in this study, we integrated remote sensing, meteorological, and field plant community...

Aims Functional group composition of a plant community is mainly driven by environmental factors and is one of the main determinants of grassland biodiversity and productivity. Therefore, it is important to understand the role of plant functional groups (PFGs) in mediating the impact of environmental conditions on ecosystem functions and biodiversi...

PhD students and Postdocs are generally rather rare at the IUNR compared to full universities where these two groups account for a big fraction of the staff. In the academic year 2019/20 two Postdocs have joined the Vegetation Ecology Research Group, Dr. Iwona Dembicz from Poland for 9 ½ months and Dr. Jinghui Zhang from China for a whole year. We...
Article
Full-text available
The relationships between community-weighted mean (CWM) functional traits and ecosystem functions have been extensively studied. However, how CWM traits and ecosystem functions respond to grazing types and whether the relationships between CWM traits and ecosystem functions mediate the response of ecosystem functions to grazing types remains contro...
Article
Full-text available
Biotic mechanisms associated with species diversity are expected to stabilize communities in theoretical and experimental studies but may be difficult to detect in natural communities exposed to large environmental variation. We investigated biotic stability mechanisms in a multi-site study across Inner Mongolian grassland characterized by large sp...

Abstract The mechanisms of species coexistence within a community have always been the focus in ecological research. Community phylogenetic structure reflects the relationship of historical processes, regional environments, and interactions between species, and studying it is imperative to understand the formation and maintenance mechanisms of comm...
Article
Although soil respiration (Rs), as the largest flux of CO2 from terrestrial ecosystems to the atmosphere, has been measured and simulated widely, its drivers on different temporal scales in high-altitude regions are not well known. These driving factors were analysed at a site upstream of the Heihe River Basin based on measurements carried out using...

The Ordos Plateau is one of the biodiversity hotspots in the arid and semi-arid areas of China. To extend our knowledge of the flora in this region, we integrated documented data and field survey data to present quantitative analyses on the taxonomy, life forms, endemism, and composition of geographical elements. In total, 790 species of seed plant...

Variations in ecosystem function in response to land-use changes may be expected to reflect differences in the functional traits of plants. In this study, we sought to reveal the relationship between trait variability and grazing management on typical steppe in Inner Mongolia, and explore the implications of this relationship for ecosystem function...
Article
To determine biodiversity, 74 plant community plots were surveyed in western Inner Mongolia between 2012 and 2014. These samples were divided into four vegetation types, including temperate steppe, temperate shrub, meadow, and desert. Four biodiversity indices (Patrick index, Simpson index, Shannon- Wiener index and Pielou index) were calculated to...

Shrub patch configuration is a long-term evolutionary response to several environmental drivers and an equilibrium state in species competition. However, the variance in configuration along the precipitation gradient and its association with climate, soil, and adjacent vegetation remains unclear. Our study aimed to assess the variation of shrub pat...

Plant community structure responds strongly to anthropogenic disturbances, which greatly influence community stability. The changes in community structure, aboveground biomass (AGB), biodiversity and community stability associated with different management practices were studied with a three-year field investigation in a temperate steppe of Inner M...

The public as well as ecologists are aware that biodiversity is declining worldwide. This has led ecologists to study the relationship between biodiversity and ecosystem stability. As a result, there is now mounting evidence supporting the hypothesis that increased diversity stabilizes ecosystem functions; however, the mechanisms underlying diversi...

Grassland is the primary vegetation type throughout the world, and covers approximately 40% of land in China, most of which has been damaged because of intensive livestock use or mowing. The management of grassland is in need of tools to diagnose the state of the vegetation, and for this reason, ecologists have begun to study plant functional trait...

The widely distributed desert ecosystem is one of the most vulnerable regions. Under the global climate change scenario, the enhancement of grazing activities has a serious impact on the composition of desert ecosystems, affecting the structure and function of desert ecosystems. In this study, we used the grassland desert of Wulatezhong Banner in Inner Mongolia as the research area. Under the conditions of grazing and enclosing, the plant hydraulic traits were used as the theoretical framework to study the adaptability of species under grazing disturbance, and the hydraulic traits were explored at the species level. The relationship between species abundance response reveals the intrinsic mechanism of the impact of grazing on species composition; we also explore the relationship between community level traits and ecosystem function response at community, and further analyze level traits and multifunctionality. Our research can help clarify the impact of grazing on the species composition and function of desert ecosystems, and provide a scientific basis for ecological construction, restoration and management of desert areas.
