متن کاملInfluences of Free-Roaming Equids on Sagebrush Ecosystems, with a Focus on Greater Sage-Grouse
Free-roaming equids (horses [Equus caballus] and burros [E. asinus]) in the United States were introduced to North America at the end of the 15th century, and have unique management status among ungulates. Legislation demands that these animals are neither hunted nor actively managed with fences and rotation among pastures, but instead constitute an integral part of the natural system of the pu...
متن کاملThe effects of exclosure on plants in the semi-arid rangeland of North Khorasan province, Iran
Abstract Over the last fifty years, most of the semi-arid rangeland in Iran has been converted to cropland without an equivalent reduction in grazing animals. This shift has led to heavy grazing pressure on rangeland vegetation. The present study has been conducted in Sisab Research Station in the North Khorasan Province to evaluate effects of long-term grazing exclosures on biodiversity of ra...
متن کاملEffects of Long-Term Livestock Grazing on Fuel Characteristics in Rangelands: An Example From the Sagebrush Steppe
Livestock grazing potentially has substantial influence on fuel characteristics in rangelands around the globe. However, information quantifying the impacts of grazing on rangeland fuel characteristics is limited, and the effects of grazing on fuels are important because fuel characteristics are one of the primary factors determining risk, severity, continuity, and size of wildfires. We investi...
متن کاملMulti-year fertility reduction in free-roaming feral horses with single-injection immunocontraceptive formulations
Context. Contraception is increasingly used as a management technique to reduce fertility in wildlife populations; however, the feasibility of contraceptive formulations has been limited until recently because they have required multiple treatments to achieve prolonged infertility. Aims. We tested the efficacy and evaluated potential side effects of two contraceptive formulations, a porcine zon...
