Impacts of Short-Term Grazing Intensity on the Plant Diversity and Ecosystem Function of Alpine Steppe on the Qinghai–Tibetan Plateau

Plants, 2022
Livestock grazing is the primary land use of grasslands worldwide. Grazing has been asserted to alter grassland ecosystem functions, such as productivity, nutrient cycling, and biodiversity conservation. However, few studies have focused on the impact of

The main driver of soil organic carbon differs greatly between topsoil and subsoil in a grazing steppe

Ecology and Evolution, 2022
Soil organic carbon (SOC) dynamics is regulated by a complex interplay of factors such as climate and potential anthropogenic activities. Livestocks play a key role in regulating the C cycle in grasslands.

Effects of different grazing intensities on grassland production in China: a meta-analysis. [PDF]

PLoS ONE, 2013
Grazing is one of the main grassland disturbances in China, and it is essential to quantitatively evaluate the effects of different grazing intensities on grassland production for grassland carbon budget and sustainable use.A meta-analysis was conducted ...

Temporal profiles of vegetation indices for characterizing grazing intensity on natural grasslands in Pampa biome

Scientia Agricola, 2016
The Pampa biome is an important ecosystem in Brazil that is highly relevant to livestock production. The objective of this study was to analyze the potential use of vegetation indices to discriminate grazing intensities on natural grasslands in the Pampa

Grazing weakens temporal stabilizing effects of diversity in the Eurasian steppe

Ecology and Evolution, 2018
Many biodiversity experiments have demonstrated that plant diversity can stabilize productivity in experimental grasslands. However, less is known about how diversity–stability relationships are mediated by grazing.

Effectiveness of Conservation Measures Based on Assessment of Grazing Intensity in the Yellow River Source Region

Land
Functional zoning diversifies the management of grazing intensity within protected areas (PAs). However, the complexity makes it difficult to assess grazing intensity and thus understand the effectiveness of PAs in reducing grazing intensity.

Effects of post-grazing forage mass on a beef cattle grazing system on Tanzânia grass pastures

Revista Brasileira de Zootecnia, 2014
The objective of this study was to evaluate the effect of grazing intensity on herbage accumulation, animal performance, and total system yield on irrigated Tanzania grass pastures under rotational stocking. The experiment was conducted from October 1999
