WQXR's Artist Propulsion Lab talks to UC biologist

Paleobotanist David Lentz studies ancient cultures in Mesoamerica

WQXR's Artist Propulsion Lab spoke with a University of Cincinnati biology professor about the environmental lessons we can learn from the ancient Maya.

UC College of Arts and Sciences paleobotanist David Lentz and his UC collaborators study ancient cultures in Mesoamerica. They have studied the ancient Maya and their use of natural resources over the centuries more than 2,000 years ago.

Lentz told WQXR that the ancient Maya initially used slash-and-burn agriculture. But over time and as their population increased, these farming methods created problems such as erosion that the ancient Maya had to address.

"They developed more sustainable agriculture and agri-forestry techniques to control erosion and intensify food production," Lentz said.

"They protected forest tracts to maintain major amounts of tree cover and conserve habitat," Lentz said.

These forests contained important medicinal plants and sources of timber, he said.

Joining Lentz on the program are composer Layale Chaker and pianist Fabian Alamazan for a discussion on music and environmental stewardship.

Lentz told WQXR that the ancient Maya protected sacred groves and planted parks around their reservoirs in some cities. But they also converted some tropical rainforest to pine savanna through continual use of slash-and-burn methods.

But Lentz said these rainforests recovered over time, giving him hope for deforested rainforests around the world today.

"There is some hope that even though some of that land in Amazonia has been degraded, if we can leave it alone long enough, these forests will return," Lentz said.

The average time to clinical diagnosis of endometriosis is nine years. Definitive diagnosis of the disease is difficult, and until recently, has relied on laparoscopic surgery. Now, as Medscape recently reported, novel clinical recommendations, advanced diagnostic tools and research into inflammation and immune responses, are bringing promise that women with endometriosis will find relief sooner and without surgery, according to experts, including Katie Burns, PhD, University of Cincinnati College of Medicine associate professor.
