This lecture is part of the David Bradford Energy and Environmental Seminar Series, organized by the Center for Policy Research on Energy and Environment. The seminars highlight scholars and practitioners from various fields working on critical research related to science policy. We invite speakers to share new research they are working on, focusing on important policy-relevant issues. Since its inception in Fall 1999, this series has hosted many speakers who are influential in science & environmental policy. Attendance by Princeton students, faculty and staff is encouraged.All seminars are open to the public on a limited basis with approved RSVP to firstname.lastname@example.orgSEMINAR TOPIC:Across all nations and all environments—marine, freshwater, artic, temperate and tropical—large-bodied animals continue to experience significant declines in distribution and abundance. Tigers, which number less than 4000 individuals and occupy only seven percent of their historic range, are no exception to this rule. The largest number of tigers occur in India, a country with over 1.3 billion people and one-third the land area of continental U.S. How is it that tigers precariously persist in India but large bodied predator populations in the U.S., with far fewer people and much greater land area, continue to be imperiled? I will discuss research findings of my Indian students studying tigers, their implications for their long-term conservation, and contrast these with efforts to encourage public support for the reintroduce gray wolves to western landscapes in the U.S.
