Identifying impediments to long-distance mammal migrations
Author(s): Seidler, R.G., Long, R.A., Berger, J., Bergen, S., and J.P. Beckmann
Year: 2014
Description/Abstract: In much of the world, the persistence of long-distance migrations by mammals is threatened by development. Even where human population density is relatively low, there are roads, fencing, and energy development that present barriers to animal movement. In order to conserve species that rely on long-distance migration, it is critical to identify existing migration impediments. This paper applies movement models to high-frequency locations of pronghorn (Antilocapra americana) in the Greater Yellowstone Ecosystem to describe the stopover sites associated with anthropogenic development. The findings demonstrate the importance of minimizing development in migration corridors in the future and of mitigating existing pressure on migratory animals by removing barriers, reducing the development footprint, or installing crossing structures.

Optimism and challenge for science-based conservation of migratory species in and out of U.S. national parks
Author(s): Berger, J., Cain, S.L., Cheng, E., Dratch, P., Ellison, K., Francis, J., Frost, H.C., Gende, S., Groves, C., Karesh, W.A., Leslie, E., Machlis, G., Medellin, R.A., Noss, R.F., Redford, K.H., Soukup, M., Wilcove, D., and S. Zack

Description/Abstract: Public agencies sometimes seek outside guidance when capacity to achieve their mission is limited. In 2008, the U.S. National Park Service (NPS) sought help from outside researchers while developing an action plan to conserve aerial, marine, and terrestrial populations of migrating wildlife. Although migration is an ecological process central to maintaining biological diversity, addressing NPS’s request required these individuals to consider attitudes and behaviors of individuals, society, and agencies. The questions, challenges, and potential solutions they present are relevant to many agencies other than NPS in which natural resource managers must grapple with extensive movements and migration of wild animals.

Moving beyond science to protect a mammalian migration corridor
Author(s): Berger, J. and S.L. Cain
Year: 2014
Description/Abstract: As the discipline of conservation biology evolves and practitioners grow increasingly concerned about how to put results into achievable conservation, it is still unclear the extent to which science drives conservation outcomes, especially across rural landscapes. This paper examines the role of science in the protection of a biological corridor for the pronghorn (Antilocapra americana) of the southern Greater Yellowstone Ecosystem.

Pronghorn Hypersensitivity To Avian Scavengers Following Golden Eagle Predation
Author(s): Jon Beckmann and Joel Berger
Year: 2005
Description/Abstract: In the high-elevation deserts of western Wyoming, a highly adaptive scavenger, the Common Raven (Corvus corax), and an avian predator, the Golden Eagle (Aquila chrysaetos), are sympatric with pronghorn (Antilocapra americana). During winter months pronghorm have been observed to respond to these avian species with extreme anti-predatory behavior.
