Evolutionary ecologist Dan Janzen to speak

BAR HARBOR — Renowned evolutionary ecologist Dan Janzen discusses a lifetime of work studying and protecting tropical forests in Costa Rica in a presentation at College of the Atlantic on Saturday, Sept. 8.

The free program begins at 5 p.m. in the Gates Community Center.

Janzen’s talk will explore his 54-plus years of being a biologist in Costa Rica. With his wife and research partner Winnie Hallwachs, Janzen established the Guanacaste Dry Forest Conservation Fund and the Area de Conservación Guanacaste.

He will discuss how a large, complex, tropical protected area can survive by being “biodeveloped,” and thereby becoming integrated with its society—and why this matters to tropical biodiversity.

Janzen, the DiMaura Professor of Conservation Biology at the University of Pennsylvania, believes that the people affected must be involved in the conservation process in order for any effort to be truly successful.

“From his pioneering work on co-evolution in the 1960’s to his leadership role in the conservation of tropical dry forests, Dan Janzen has always been on the forefront of ecological and evolutionary theory and practice,” said COA Professor John Anderson. “His work has been informed by an intense appreciation of detail, and livened by a delightful sense of humor that makes students, friends, and colleagues all look for the ‘next Janzen paper,’ knowing that we will be surprised, amused, and above all informed and inspired.”
