Migratory ungulates may be particularly vulnerable to the challenges imposed by growing human populations and climate change. These species depend on vast areas to sustain their migratory behavior, and in many cases come into frequent contact with human populations outside protected areas. They may also act as spatial coupling agents allowing feedbacks between ecological systems and local econo...

Wild herbivores and livestock share the majority of rangelands worldwide, yet few controlled experiments have addressed their individual, additive, and interactive impacts on ecosystem function. While ungulate herbivores generally reduce standing biomass, their effects on aboveground net primary production (ANPP) can vary by spatial and temporal context, intensity of herbivory, and herbivore id...

Climate change affects public land ecosystems and services throughout the American West and these effects are projected to intensify. Even if greenhouse gas emissions are reduced, adaptation strategies for public lands are needed to reduce anthropogenic stressors of terrestrial and aquatic ecosystems and to help native species and ecosystems survive in an altered environment. Historical and con...

Bovine tuberculosis at the animal–human–ecosystem interface Introduction Bovine tuberculosis is a chronic disease of animals caused primarily by Mycobacterium bovis (M. bovis), a member of the M. tuberculosis complex. The disease is characterized by progressive development of specific granulomatous lesions or tubercles in lung tissue, lymph nodes or other organs. The incubation period ranges fr...

Bovine tuberculosis (bTB) is a zoonotic disease caused by Mycobaterium bovis, and is transmissible to humans, wildlife and domestic livestock. In the northern Lower Peninsula of Michigan, white-tailed deer (Odocoileus virginianus) serve as a reservoir for the disease and pose a significant threat to domestic cattle and captive cervids. Scientists at USDA, APHIS, Wildlife Services, National Wild...

Savannas worldwide are vital for both socioeconomic and biodiversity values. In these ecosystems, management decisions are based on the perception that wildlife and livestock compete for food, yet there are virtually no experimental data to support this assumption. We examined the effects of wild African ungulates on cattle performance, food intake, and diet quality. Wild ungulates depressed ca...

The COVID-19 pandemic provided an opportunity to assess the impacts of a global disturbance on conservation land uses and learn from responses crisis enable more resilient systems. To understand socio-economic diverse wildlife working lands COVID-19, we surveyed owners managers 78 private ranches (wildlife lands), 23 agricultural farms (conventional lands) six public protected areas in South Af...
