Yet all organisms, including humans, cooperate with beneficial microbes. \u201cFor example, our gut bacteria give us vitamins and nutrients and are crucial to our well-being,\u201d Johnson said.<\/p>\n
Microbes also cooperate with plants. Johnson and the other authors discuss diverse economic strategies employed by microbes, including avoiding bad trading partners, saving for a rainy day and building local business ties.<\/p>\n
The paper, \u201cEvolution of Microbial Markets,\u201d arose from a working group of scientists at the Lorentz Center in Leiden, The Netherlands, in January 2012. Johnson, a professor in the\u00a0School of Earth Sciences & Environmental Sustainability and the Department of\u00a0Biological Sciences, was invited to participate in the workshop during her sabbatical while she was a Fulbright Scholar living in Prague.<\/p>\n","protected":false},"excerpt":{"rendered":"
A closer look at microbes reveals there is big business going on in their very small world, and sometimes we are part of the transaction. An international team of researchers, including Northern Arizona University scientist Nancy Collins Johnson, argue in the Proceedings of the National Academy of Sciences that microbes, like many animals, can evolve…<\/a><\/p>\n","protected":false},"author":46,"featured_media":28580,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[11],"tags":[564,561,562,560,38,24,563],"class_list":["post-28569","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research-academics","tag-fulbright","tag-microbes","tag-microbial-trading","tag-nancy-collins-johnson","tag-nau","tag-northern-arizona-university","tag-pnas"],"acf":[],"_links":{"self":[{"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/posts\/28569","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/users\/46"}],"replies":[{"embeddable":true,"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/comments?post=28569"}],"version-history":[{"count":0,"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/posts\/28569\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/media\/28580"}],"wp:attachment":[{"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/media?parent=28569"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/categories?post=28569"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/in.nau.edu\/news\/wp-json\/wp\/v2\/tags?post=28569"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
