E.O. Wilson, Pellegrino University Professor Emeritus, will host a lecture and benefit dinner with biologist Daniel H. Janzen, from the University of Pennsylvania, on Oct. 1. The event, titled “Biodiversity: Conserving Through Knowing,” is in support of conservation in Area de Conservación Guanacaste (ACG), which is a tropical treasure of 163,000 hectares located in northwestern Costa Rica. The event includes a free public lecture and discussion followed by an optional ticketed dinner.

Currently, the ACG comprises 2 percent of Costa Rica, and 2.6 percent of the world’s biodiversity — an estimated 230,000 species of plants and animals. It is the product of one of the world’s most successful habitat restoration and conservation efforts, and it supports research at the leading edge of ecology, evolutionary biology, biotechnology, biodevelopment, child education, and conservation. It is also a UNESCO World Heritage site.

The lecture will take place at Tsai Auditorium, 1730 Cambridge St., at 6 p.m. Donations are encouraged. The benefit dinner will be held at 8 p.m. at UpStairs on the Square, and tickets are available here. All proceeds will benefit the Guanacaste Dry Forest Conservation Fund.
