Host Meagan Cantwell talks to Staff Writer Elizabeth Pennisi about the first comprehensive survey of microbes in Hawaii\u2019s Waimea Valley, which revealed that plants and animals get their unique microbiomes from organisms below them in the food chain or the wider environment.   Going global, Meagan then speaks with Erle Ellis, professor of geography and environmental science at the University of Maryland, Baltimore County, about a project that aggregated the expertise of more than 250 archaeologists to map human land use over the past 10,000 years. This detailed map will help fine-tune climate models.   This week\u2019s episode was edited by Podigy.   Ads on this show: Science Sessions Podcast; Kroger   Listen to previous podcasts   About the Science Podcast   [Image: Chris Couderc\/Flickr; Music: Jeffrey Cook]      ++  Authors: Meagan Cantwell; Elizabeth Pennisi ","author_name":"Science Magazine Podcast","author_url":"http:\/\/www.sciencemag.org","html":"
