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.

Human Impacts on Forest Biodiversity in Protected Walnut-Fruit Forests in Kyrgyzstan [PDF]

, 2014
We used a spatially explicit model of forest dynamics, supported by empirical field data and socioeconomic data, to examine the impacts of human disturbances on a protected forest landscape in Kyrgyzstan.

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

Differentiated Dairy Grazing Intensity in the Northeast

Journal of Dairy Science, 2000
As the dairy industry in the Northeast experienced difficult economic conditions in the 1990s, grazing was increasingly viewed as an option for feeding dairy cattle. This analysis used a large sample of dairy farms randomly drawn from three states (Pennsylvania, Vermont, and Virginia) in early 1997 to compare important aspects of the farming operations

Higher sustainability performance of intensive grazing versus zero-grazing dairy systems [PDF]

Agronomy for Sustainable Development, 2012
Although grazing of dairy cows is an integral part of dairy farming in many European countries, farmers today more often choose for zero-grazing systems, where cows are housed throughout the year. Some studies already compared grazing and zero-grazing systems for specific issues such as labor efficiency, environmental impact, or animal welfare.

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.
