Yet, the genetic variability of ring-width and radial growth\u2013climate relationships among geographic origins within species is rarely investigated. This is what we analyzed in the European black pine,\u00a0<i>Pinus nigra<\/i>\u00a0J.F. Arnold (1785), a forest tree species widely but patchily distributed. Using four partially replicated common gardens in France, we show that late spring minimum temperatures affect radial growth negatively and early summer precipitations positively across all provenances. In contrast, there was a strong provenance effect on mean ring-widths, as well as high phenotypic plasticity and significant genotype by environment interactions in most provenances and all subspecies. Provenances of the subspecies\u00a0<i>P.n.<\/i>\u00a0subsp.\u00a0<i>salzmannii<\/i>\u00a0often displayed the smallest mean ring widths except in the least fertile common garden. A few provenances of\u00a0<i>P.n.<\/i>\u00a0subsp.\u00a0<i>pallasiana<\/i>,\u00a0<i>P.n.<\/i>\u00a0subsp.\u00a0<i>laricio<\/i>\u00a0and\u00a0<i>P.n.<\/i>\u00a0subsp.\u00a0<i>nigra<\/i>\u00a0performed equally well in all common gardens. Climate smart forestry should consider provenance and not just subspecies recommendations for plantations where black pine is not native, either for ecological restoration or timber production.<\/p>\n<p><strong>Keywords<br \/>\n<\/strong>Common garden; Genetic diversity; Phenotypic plasticity; Climate change; Dendroecology<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1186\/s13595-026-01347-5'  style='float: right; ' ><\/div>\n<p><strong>Publication<br \/>\n<\/strong>Giovannelli, G., Tallieu, C., Davi, H.\u00a0<i>et al.<\/i>\u00a0Adaptive effects of geographic origin on ring-width and radial growth\u2014climate relationships in\u00a0<i>Pinus nigra<\/i>\u00a0Arnold, the European black pine.\u00a0<i>Annals of Forest Science<\/i>\u00a0<b>83<\/b>, 31 (2026). <a href=\"https:\/\/doi.org\/10.1186\/s13595-026-01347-5\">https:\/\/doi.org\/10.1186\/s13595-026-01347-5<\/a><\/p>\n<p><strong>Data availability\u00a0<\/strong><br \/>\nThe data that support the findings of this study are available online: <a href=\"https:\/\/doi.org\/10.57745\/SKPSYI\">https:\/\/doi.org\/10.57745\/SKPSYI<\/a><\/p>\n<p><strong>Handling editor<br \/>\n<\/strong>Erwin Dreyer<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Research paper Key Message Radial growth is a fitness related trait that is expected to vary among forest tree populations when habitat conditions change.
