Yet continental relative humidity is a key climatic parameter in the evolution of ecosystems. In this presentation, I will show how continental relative humidity controls plant transpiration; how changes in humidity are recorded by the triple isotopic composition of oxygen in water and silica in plants, which we are able to measure at CEREGE; why we are trying to reconstruct these changes over the last 3,000 years in intertropical Africa; and how this could enable us to better predict future changes in continental relative humidity and ecosystems in intertropical regions.<\/p><p>The presentation will be in French and will be available for streaming (<a href=\"http:\/\/streaming-a.osupytheas.fr\/embed\/live.html\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">http:\/\/streaming-a.osupytheas.fr\/embed\/live.html<\/a>)<\/p><\/div><\/div><\/div><div class=\"event-info-section clearfix\">\u00a0<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>7 septembre, 13h30, Amphith\u00e9\u00e2tre Pasteur, CEREGE Arbois &#8220;L\u2019humidit\u00e9 relative atmosph\u00e9rique continentale r\u00e9v\u00e9l\u00e9e par la triple composition isotopique de l\u2019oxyg\u00e8ne de l\u2019eau et de la silice des plantes&#8221; R\u00e9sum\u00e9 : Si [&hellip;]<\/p>\n","protected":false},"author":724,"featured_media":15751,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[19],"tags":[],"class_list":["post-20692","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-archive"],"acf":[],"publishpress_future_action":{"enabled":false,"date":"2026-05-07 10:32:10","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/posts\/20692","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/users\/724"}],"replies":[{"embeddable":true,"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/comments?post=20692"}],"version-history":[{"count":5,"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/posts\/20692\/revisions"}],"predecessor-version":[{"id":20741,"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/posts\/20692\/revisions\/20741"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/media\/15751"}],"wp:attachment":[{"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/media?parent=20692"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/categories?post=20692"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.cerege.fr\/en\/wp-json\/wp\/v2\/tags?post=20692"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
