Eine internationale Studie unter Leitung der Universit\u00e4t G\u00f6ttingen hat die Faktoren untersucht, welche die Verbreitung von Samenpflanzen beeinflussen und wie sich diese Muster im Laufe der Jahrmillionen ver\u00e4ndert haben. Die Forschung unterstreicht, dass Umweltbedingungen und geografische Barrieren verschiedene Pflanzenarten unterschiedlich stark beeinflussen und damit die globale Pflanzenvielfalt zu einem hohen Ma\u00df mitgestalten. Die Ergebnisse wurden in der Fachzeitschrift <em>Nature Ecology &amp; Evolution <\/em>ver\u00f6ffentlicht.<\/p>\n<p style=\"font-weight: 400;\">Die Forschenden analysierten rund 270.000 Samenpflanzenarten weltweit. Mithilfe neuartiger statistischer Verfahren, welche die Verbreitung von Pflanzen mit ihren evolution\u00e4ren Verwandtschaftsbeziehungen verbinden, konnten sie moderne Umweltdaten mit der Klima- und Geografiegeschichte der Erde \u00fcber Millionen von Jahren kombinieren. Das Team untersuchte, wie Ver\u00e4nderungen in Klima, Boden und anderen Umweltfaktoren bestimmen, wo Pflanzen gedeihen k\u00f6nnen, und wie physische Barrieren \u2013 also zum Beispiel Ozeane, Gebirgsz\u00fcge und Gebiete mit lebensfeindlichem Klima \u2013 die Ausbreitung von Pflanzen einschr\u00e4nken.<\/p>\n<p style=\"font-weight: 400;\">Die Ergebnisse zeigen, dass der Einfluss von Umweltbedingungen, insbesondere dem Klima, \u00fcber evolution\u00e4re Zeitskalen hinweg gleich hoch bleibt. Geografische Barrieren wie Ozeane und Gebirge hinderten besonders die Ausbreitung von Pflanzengruppen, die erst in j\u00fcngerer Zeit entstanden sind, beeinflussten aber kaum evolutiv \u00e4ltere Pflanzengruppen, die mehr Zeit hatten, sich weit zu verbreiten. Die Positionen und Bewegungen der tektonischen Platten in der Vergangenheit beeinflussten die Pflanzenvielfalt nur gering, wobei die st\u00e4rksten Auswirkungen vor 20 bis 50 Millionen Jahren zu verzeichnen waren.<\/p>\n<p style=\"font-weight: 400;\">\u201eDie Ergebnisse verdeutlichen einen grundlegenden Prozess in der Natur\u201c, so Erstautorin Dr. Lirong Cai vom iDiv und der Universit\u00e4t G\u00f6ttingen. \u201eWenn sie genug Zeit haben, k\u00f6nnen Pflanzen selbst gro\u00dfe Entfernungen und hohe geografische H\u00fcrden \u00fcberwinden, aber sie bleiben oft durch das Klima, auf das sie treffen, begrenzt.\u201c<\/p>\n<h3><strong>Originalpublikation<\/strong><\/h3>\n<p>(Forschende mit iDiv-Affiliation und Alumni sind fett hervorgehoben)<\/p>\n<div><span lang=\"EN-GB\"><strong>Cai, L.<\/strong>, Kreft, H., Denelle, P., Taylor, A., Craven, D., Dawson, W., Essl, F., van Kleunen, M., Pergl, J., Py\u0161ek, P., <strong>Winter, M.,<\/strong> Cabezas, F.J., Wagner, V., Pelser, P.B., Wieringa, J.J., and Weigelt, P. <\/span><i><span lang=\"EN-GB\">(2024). <\/span><\/i><span lang=\"EN-GB\">Environmental filtering, not dispersal history, explains global patterns of phylogenetic turnover in seed plants at deep evolutionary timescales.<\/span><i><span lang=\"EN-GB\"> Nature Ecology and Evolution.<\/span><\/i><span lang=\"EN-GB\"> DOI:<\/span><span lang=\"EN-GB\"><a href=\"https:\/\/doi.org\/10.1038\/s41559-024-02599-y\">10.1038\/s41559-024-02599-y<\/a><\/span><\/div>\n<h3><\/h3>\n<h3>Ansprechpartner<\/h3>\n<p><strong>Dr Lirong Cai<\/strong><br \/>\nUniversit\u00e4t G\u00f6ttingen<br \/>\nDeutsches Zentrum f\u00fcr integrative Biodiversit\u00e4tsforschung (iDiv) Halle-Jena-Leipzig<br \/>\nTelefon: +49 341 97 33176<br \/>\nEmail: &#x6c;&#x69;&#x72;&#x6f;&#110;&#103;&#46;&#99;ai&#64;&#x69;&#x64;&#x69;&#x76;&#x2e;&#100;&#101;<\/p>\n<p><strong>Christine Coester<\/strong><br \/>\nMedien und Kommunikation<br \/>\nDeutsches Zentrum f\u00fcr integrative Biodiversit\u00e4tsforschung (iDiv) Halle-Jena-Leipzig<br \/>\nTelefon: +49 341 97 33197<br \/>\nEmail: &#x63;&#x68;&#114;&#105;&#115;t&#x69;&#x6e;&#x65;&#46;&#99;oe&#x73;&#x74;&#x65;&#114;&#64;i&#x64;&#x69;&#x76;&#46;&#100;&#101;<\/p>\n<\/div>\n                            <\/div>\n                        <\/div>\n    <\/div>\n<\/div>\n\n<div class=\"textbildrepeater pb-24 pt-0 no-bg modulclass \" id=\"\">\n    <div class=\"container\">\n        <div class=\"row\">\n                                                                <div class=\"pb-0   mod_bild  col-md-4 offset-md-2 pos_top\">\n                            <div class=\"bildrepeater \" id=\"\">\n    <div class=\"relativ\"><img decoding=\"async\" class=\"responsiv desktop\" src=\"https:\/\/www.idiv.de\/wp-content\/uploads\/2025\/03\/20240519_191421_Resized.jpg\" height=\"\" width=\"\" alt=\"idiv-Mountains in the distance with a stream in the foreground.\"\/><img decoding=\"async\" class=\"responsiv mobile\" src=\"https:\/\/www.idiv.de\/wp-content\/uploads\/2025\/03\/20240519_191421_Resized.jpg\" height=\"\" width=\"\" alt=\"idiv-Mountains in the distance with a stream in the foreground.\"\/><a href=\"#\" class=\"cr\" role=\"button\">\n<svg  xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"22\" height=\"22\" viewBox=\"0 0 22 22\">\n    <rect id=\"BG\" width=\"22\" height=\"22\" rx=\"11\" fill=\"#fff\"\/>\n    <g id=\"Wrapper\" transform=\"translate(-1 -1)\">\n        <g id=\"Icon_material-copyright\" data-name=\"Icon material-copyright\">\n            <circle id=\"Ellipse_30\" data-name=\"Ellipse 30\" cx=\"8\" cy=\"8\" r=\"8\" transform=\"translate(4 4)\" fill=\"#fff\"\/>\n            <path id=\"Icon_material-copyright-2\" data-name=\"Icon material-copyright\" d=\"M9.464,10.088a2.045,2.045,0,0,1,.24-.7,1.4,1.4,0,0,1,.472-.5,1.42,1.42,0,0,1,.728-.184,1.45,1.45,0,0,1,.5.1,1.29,1.29,0,0,1,.416.288,1.54,1.54,0,0,1,.272.424,1.4,1.4,0,0,1,.112.512H13.64a2.864,2.864,0,0,0-.224-1.032,2.4,2.4,0,0,0-.56-.808,2.613,2.613,0,0,0-.864-.528,3.09,3.09,0,0,0-1.112-.184,3.127,3.127,0,0,0-1.36.272,2.751,2.751,0,0,0-.96.736,3.007,3.007,0,0,0-.568,1.088A4.685,4.685,0,0,0,7.8,10.9v.216a4.684,4.684,0,0,0,.184,1.312,2.908,2.908,0,0,0,.568,1.08,2.731,2.731,0,0,0,.96.728,3.246,3.246,0,0,0,1.36.272,3.051,3.051,0,0,0,1.056-.184,2.729,2.729,0,0,0,.864-.5,2.442,2.442,0,0,0,.592-.752,2.153,2.153,0,0,0,.24-.92H12.192a1.139,1.139,0,0,1-.12.464,1.177,1.177,0,0,1-.288.368,1.26,1.26,0,0,1-.416.24,1.589,1.589,0,0,1-.48.08,1.359,1.359,0,0,1-.712-.184,1.4,1.4,0,0,1-.472-.5,2.09,2.09,0,0,1-.24-.7,5.392,5.392,0,0,1-.064-.8V10.9a5.33,5.33,0,0,1,.064-.808ZM11,3a8,8,0,1,0,8,8A8,8,0,0,0,11,3Zm0,14.4A6.4,6.4,0,1,1,17.4,11,6.408,6.408,0,0,1,11,17.4Z\" transform=\"translate(1 1)\" fill=\"#4d4d4d\"\/>\n        <\/g>\n    <\/g>\n<\/svg>\n<span>H.
