SUMMARY:Evolutionary history of boreotropical lineages: Hypericum (Hypericaceae) and Euphorbia subgenus Esula (Euphorbiaceae)
DESCRIPTION:<p style="text-align:justify">	<span><span><span><span><span style="color:#000000">Because of its unique climatic history, the northern hemisphere provides a natural laboratory to study the effects of climate cooling on biodiversity on a continental scale. In the early Cenozoic era, the global temperature was high, allowing paratropical conditions at high latitudes. During this period, the boreotropical forest covered the Holarctic region. The climatic cooling that took place 35 million years ago promoted the disappearance and replacement of this ancient "boreotropical" biome by different types of temperate and seasonal vegetation. In this seminar we will explore the evolutionary and biogeographic history of two plant lineages with boreotropical ancestors, the genus <em>Hypericum</em> L. and <em>Euphorbia</em> subgenus <em>Esula </em>Pers., two of the most species-rich groups of angiosperms.</span></span></span></span></span></p><p style="text-align:justify">	<span><span><span><span><span style="color:#000000">This seminar is framed within </span></span></span></span></span>the activites of the RCCHU Study Group <em>'Botanical Collections and Herbaria: New Insights and Challenges'</em></p><p style="text-align:justify">	<drupal-media data-entity-type="media" data-entity-uuid="042790dd-19d9-4873-9324-3ad2dce7c1bd" alt="RJB"></drupal-media></p><p style="text-align:justify">	                                                    <a href="https://harvard.zoom.us/j/96079112456?pwd=emltU3cyRTZmbEZwNXVDUWN6dWtCZz09%20%20" title="Hypericum">You can follow this seminar here</a></p><p style="text-align:justify">	<span><span><span><span><span style="color:#000000"><strong>Speaker</strong>: <strong>Irene Masa-Iranzo <em>(</em></strong><em>Real Jardín Botánico de Madrid, CSIC; Universidad Autónoma of Madrid, UAM;  Madrid, Spain)</em></span></span></span></span></span></p><p style="text-align:justify">	<strong>Sponsors</strong>: <span><span><span><span><span style="color:#000000">Real Jardín Botánico de Madrid (RJB-CSIC); Universidad Autónoma of Madrid (UAM); RCCHU</span></span></span></span></span></p><p style="text-align:justify">	 </p><p style="text-align:justify">	 </p>
