The Natural History Institute (NHI) presents Peter Sherman, Ph.D., who will speak on the natural history of slave-making ants, their victims and a macabre parasite that haunts them both at 7 p.m. Thursday, Feb. 7, at NHI, 126 N. Marina St., Prescott.

Sherman’s presentation, “Slave Raiding Ants of Prescott: Natural history of the ants, their slaves, and the parasites that attack them both” will discuss the 400-million-year history of insects that produced some of the most bizarre and fascinating relationships found in nature.

“Come prepared to be surprised,” an NHI press release states.

Sherman is a systems ecologist studying the world’s most complex ecosystem: the tropical lowland rainforest. In addition, he has published scientific articles on the slave-raiding ants of the Chiricahua Mountains of Arizona, the economics of web building in spiders of upstate New York, the distributions of alligators in Texas swamps, and effects of the giant land crabs on plant diversity in Costa Rica’s Corcovado National Park.

Sherman earned his doctorate degree in rainforest systems ecology from the University of Michigan in 1997. He has been a professor and chair of the Master of Arts program in Environmental Studies at Prescott College since 2005.
