Scientists are not well known as communicators but a memorable few have mastered both fields - Aldo Leopold, Rachel Carson and E.O. Wilson, for example. The University of Nevada at Reno will pay tribute over the next seven months to similar contemporary scientists through a series of free public readings and discussions titled Literary Natural History: Scientists and Artists. The series, which runs October through April, includes columnist David Quammen; Richard K. Nelson, an anthropologist who has studied Alaskan hunting cultures; Louise B. Young, a geophysicist who worked in a radiation lab during World War II; and ethnobotanist Gary Paul Nabhan.
