Vegetation classification of Stipa steppes in China, with reference to the International Vegetation Classification [PDF]

Vegetation Classification and Survey (VCS), 2022
Aims: The vegetation classification system of China (China-VCS) is not completed. Stipa steppes are the most important steppes in China. Here we made optimal use of available plot data to classify Stipa steppes into associations in a way that is ...

Biome regulates the effects of long‐term grazing on soil microbial diversity

Journal of Sustainable Agriculture and Environment, 2023
Introduction Livestock overgrazing represents one of the most destructive uses of land in terrestrial ecosystems and threatens biodiversity. However, understanding the effects of livestock overgrazing on below‐ground soil microbial diversity is limited ...

Plant functional diversity and species diversity in the Mongolian steppe. [PDF]

PLoS ONE, 2013
The Mongolian steppe is one of the most important grasslands in the world but suffers from aridization and damage from anthropogenic activities. Understanding structure and function of this community is important for the ecological conservation, but has ...

Using the dynamics of productivity and precipitation-use efficiency to detect state transitions in Eurasian grasslands

Frontiers in Ecology and Evolution, 2023
In the face of accelerated global dryland expansion and grassland degradation, signaling grassland ecosystem state transitions is an ongoing challenge in ecology.

Grazing effects on intraspecific trait variability vary with changing precipitation patterns in Mongolian rangelands

Ecology and Evolution, 2020
Functional traits are proxies for plant physiology and performance, which do not only differ between species but also within species. In this work, we hypothesized that (a) with increasing precipitation, the percentage of focal species which ...

Short-term land degradation driven by livestock grazing does not affect soil properties in semiarid steppe rangelands

Frontiers in Environmental Science, 2022
The soil–vegetation relationships are reciprocal and fundamental for terrestrial ecosystem integrity. However, the long-term degradation of vegetation cover alters edaphic conditions, which can lead to degradation of habitats, and obstructs proper ...

The diversity and co-occurrence patterns of diazotrophs in the steppes of Inner Mongolia

, 2017
Soil diazotrophs possess the function of fixing atmospheric NZ into biologically available ammonium in terrestrial ecosystems. However, there are limited studies into how diazotrophic communities change when grassland environments differ.

Effects of grazing intensity and topography on steppe vegetation and soil properties of Mt. Aragats, Armenia

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
Steppes are large ecosystems and diverse in plant composition and soils-climatic conditions. Steppes have been used for pastoralism for centuries. Few studies have considered interactive effects of grazing intensity and topography on steppe productivity,
