Next Sustainability Series Lecture is on Oct. 22

“What Obsidians Can Tell Us about the Cultural Landscape”
10/9/13

The University of Wisconsin-Fond du Lac’s fall lecture series on sustainability continues at 12:30 p.m. and 6:30 p.m. on Tuesday, Oct. 22 in UC-114 (LGI Room).

“What Obsidians Can Tell Us about the Cultural Landscape” will be presented by William Whitehead, anthropology lecturer. He will focus on the science and anthropology of obsidian sourcing in San Pedro de Atacama, Northern Chile. The natural glass called obsidian has been used by humans to make artifacts where ever it is encountered on the landscape.  It is almost the perfect lithic material to use when tracing human movement, trade, technology and landscape use.  Learn more from an archaeological professional with over 20 years of experience in excavations, lab and the sub field of archaeometry. 

The final lecture in the series “Invasive Plant Species and Chemical Warfare” is at 12:30 p.m. and 6:30 p.m. on Tuesday, Nov. 19 in UC-114 (LGI Room). Presented by David Demezas, biological sciences professor, attendees will learn about plants that produce a myriad of compounds for different purposes including protection against herbivores and invasive processes. This may be one mechanism that allows invasive plant species to become established in new territories. Garlic mustard is a highly invasive plant species that is found in many different locations in Fond du Lac County. Results from undergraduate students' research projects on compounds from garlic mustard will be presented.

The lectures are free and open to the public.
