- Abstract:
- ... Pastures and rangelands are a dominant portion of global agricultural land and have the potential to sequester carbon (C) in soils, mitigating climate change. Management intensive grazing (MIG), or high density grazing with rotations through paddocks with long rest periods, has been highlighted as a method of enhancing soil C in pastures by increasing forage production. However, few studies have e ...

However, increasing interest in local food production and on-going challenges posed by drought and fire on Western rangelands give reason to believe that the importance of Northeastern grass-based ruminant meat could grow in the near future. Using an integrated modeling approach, the present study quantifies curr ...

A deeper understanding of rainfall and runoff dynamics can assist in the development of sustainable management strategies. Current methods to measure surface runoff (e.g., natural runoff plots, rainfall simulation and overland flow experiments, modeling approaches) have many advantages but can be proh ...

Agriculturists are advocating for the integration of crop-livestock systems (ICLS) to recouple nutrient cycles, improve biodiversity, and increase resilience of agricultural operations. We address the benefits of ICLS in the Great Plains, ...

On rangeland landscapes, management is often focused on provisioning services (e.g., livestock) but can also include maintaining biodiversity. Rangeland landscapes are often large and complex, suggesting understanding the invasion and management efforts is best done at mul ...

- Abstract:
- ... Rangeland scientists have long relied on thermocouples for measuring temperature, especially in agris—in the field, under the extreme conditions of wildland fire. But the electronics required to sense and record thermocouple data remain expensive to both purchase and protect from exposure to heat and flames. Open-source, do-it-yourself (DIY) electronics platforms such as Arduino are increasingly p ...

- Abstract:
- ... Beef cattle grazing patterns are influenced by topography in that cattle generally select grazing sites near water while avoiding steep, rugged terrain; therefore, forage is often left ungrazed in the mountainous uplands whereas lowland riparian zones can be heavily grazed. Improving uniformity in beef cattle terrain-use provides opportunities to increase forage harvest and sustain sensitive ecosy ...

- ... One-seed juniper (Juniperus monosperma [Englem.] Sarg.) encroachment into grassland habitats is facilitated by a diverse group of frugivores. To test seed germination after gut passage, we collected pellets or scats containing mature seeds from four frugivore groups: passerine (perching) birds, lagomorphs (hares and rabbits), mesocarnivores (coyotes and foxes), and porcupines. For comparison of ge ...

Honey mesquite (Prosopis glandulosa Torr.) may maintain apical dominance after a treatment that causes partial top-kill (PTK) and leaves canopies with “stem flagging.” In contrast, top-killing treatments stimulate multistemmed regrowth (i.e., basal sprouting; BSP). Because this difference may impact competition with grasses, a better understanding of physiology associated with PTK and BSP canopies ...

- Abstract:
- ... Flood irrigation on western rangelands is important for diverse social and ecological reasons, providing forage for many agricultural operations and maintaining many critical wetlands across the region. However, recent debate over the efficiency of flood irrigation and resulting transition to other “more efficient” types of irrigation has put many of the working wet meadows sustained by flood irri ...

- Abstract:
- ... Gastrointestinal nematode (GIN) infections in cattle cause appetite suppression which leads to poor feed conversion, reduced weight gain and reduced milk production. Overuse and exclusive reliance on anthelmintic drugs has resulted in widespread resistance in many parasitic nematode species infecting livestock making control increasingly difficult. Wild ruminants are competent hosts of a number of ...

Empirical findings expand current understandings of livelihood shift in Maa ...
