Abstract:
... Grazing lands provide many goods and ecosystem services, such as forage, livestock, soil carbon (C) storage, biodiversity, and recreational opportunities. Ensuring the long-term sustainability of grazing lands requires optimal management to simultaneously balance livestock productivity for sustaining human food and nutritional demands while reducing environmental impacts, such as greenhouse gases ...

Abstract:
... Collaborative adaptive management (CAM) is hypothesized to benefit management of rangeland ecosystems, but the presumed benefits have seldom been quantified, and never in a multipaddock rotational grazing system. Here, we evaluated average daily weight gain (ADG) of livestock (kg steer⁻¹ d⁻¹) in four grazing management treatments during the summers of 2016−2018 in a semiarid shortgrass steppe. The ...

Abstract:
... Soil organic carbon (SOC) plays a key role in sustaining pasture agroecosystem function and its rate of accumulation can be influenced by management practices including manure deposition and grazing intensity. This study was conducted to determine the impacts of 13-years of different pasture management practices on SOC content and aggregation. The field experiment was conducted in a watershed cons ...

Abstract:
... Multiple disturbances can have mixed effects on biodiversity. Whether the interaction of sequential disturbances drives local extinctions or promotes diversity depends on the severity of biomass reductions relative to any stabilizing and/or equalizing effects generated by the disturbance regimes. Through a manipulative mesocosm experiment, we examined how warming events in the fall and simulated g ...

Abstract:
... In the Nama-Karoo, South Africa, rainfall and grazing by livestock are two important drivers of botanical composition. Summer rains are advantageous particularly to the grass layer, whereas the characteristic dwarf shrubs survive better than grasses during drought, and benefit from rainfall during cool months. Heavy grazing by livestock during summer reduces the abundance of grasses, whereas winte ...

Abstract:
... Rhipicephalus microplus is the most significant tick of livestock and its control is particularly challenging due to its resistance to commercial acaricides. Pasture rotation is considered a management strategy that could help control R. microplus, however, the literature only contemplates mathematical models and little is known about the effects of this practice in the field. The objective of thi ...

Abstract:
... Grazing exclusion of grasslands has traditionally been considered to reduce nitrogen inputs and decrease nitrous oxide (N₂O) emissions. However, recent studies have shown that grazing exclusion may increase N₂O emissions because of freeze-thaw cycles. In this study, year-round N₂O fluxes (including high-frequency measurements during the freeze-thaw cycles) were measured in three sites that include ...

Bement (1969) developed a stocking rate (SR) guide for yearling cattle grazing shortgrass steppe based on relationships among average daily weight gain (ADG, kg · d⁻¹), beef production per hectare (BP, kg · ha⁻¹), and stocking rate (animal unit days, AUD · ha⁻¹) measured in long-term grazing experiments conducted from 1940 to 1963. These analyses identified an optimal biophysical SR of 13.5 AUD ·  ...

Abstract:
... Grazing systems emit greenhouse gases, which can, under specific agro-ecological conditions, be partly or entirely offset by soil carbon sequestration. However, any sequestration is time-limited, reversible, and at a global level outweighed by emissions from grazing systems. Thus, grazing systems are globally a net contributor to climate change and the time scale of key processes needs to be facto ...

Abstract:
... In the context of grazing, the intermediate disturbance hypothesis (IDH) predicts that plant diversity peaks under moderate grazing, resulting in a hump‐shape pattern for the grazing–diversity relationship. Although this has been debated due to contradictory empirical results, the IDH is still widely accepted among rangeland ecologists. The Milchunas–Sala–Lauenroth (MSL) model predicts that in ari ...
