Island Biodiversity - Tracking Human Influences

In this video, archaeologist Dr. Torben Rick talks about the impacts early inhabitants of North America had on island and coastal ecosystems.

Description: 

Meet Dr. Torben Rick, an archaeologist at the National Museum of Natural History. Join him in analyzing archaeological evidence of human life on islands. Look back over thousands of years of influence of humans on the West Coast (Channel Islands) and East Coast (Chesapeake Bay). See how changing environmental conditions interacted with human lifestyles to shape the biodiversity of the islands. Follow Torrey as he uses radiocarbon-dating of bones, DNA analysis, and other techniques to tackle elusive questions such as how foxes arrived in the Channel Islands. Find out how archaeological information can help manage island ecosystems today. This show aired November 6, 2014.
