Estudio demuestra que la cerca fronteriza impide el paso de osos de Arizona a México:
New research has found that black bears and other large carnivores may be impacted by urbanization, roads and border security activities along the U.S.–Mexico border. The paper was co-authored by WCS conservationist Jon Beckmann, along with researchers from the USDA-National Wildlife Research Center, Purdue University, and the Arizona Game and Fish Department. Beckmann and his colleagues conclude that protecting wildlife corridors on the highly diverse border area will help to mitigate the effects of habitat fragmentation and prevent genetic isolation for populations of bears, mountain lions, jaguars, and other species. Study findings will be disseminated to the Department of Homeland Security and other agencies involved with safeguarding the border.
