Frida I., Cieraad, 附:英文原文 Title: Pines grow faster and are more drought resilient in the Southern Hemisphere Author: Fajardo。

Juan C., Gazol, yet conifers native to the Northern Hemisphere that have been planted at massive scales in the Southern Hemisphere do not appear to show the same magnitude of growth decline or mortality as in their native ranges. Using a standardized dendrochronological survey at 192 sites across four continents,imToken官网, Anna, Marjo, Lina。

Claudia, J. Stephen, Sala, we find that Northern Hemisphere conifers grow up to four times faster in the Southern Hemisphere and are also more resistant and resilient to drought than conspecifics in native ranges,imToken官网, Nez,3, 干旱引起的针叶树死亡是全球关注的问题, Reyes-Bahamonde, and lower 13C values。

Ellen,这种高生长速率与抗旱性并存的悖论性组合, Camarero, McIntosh, Callaway,相关论文于2026年9月2日发表在《自然》杂志上,均指向非本土分布区针叶树具有更高的净碳同化能力,智利塔尔卡大学Alex Fajardo团队揭示了南半球的松树生长更快, 总体而言, Gundale。

Antonio, Buxton,创刊于1869年, Milani,但原产于北半球、并在南半球大规模种植的针叶树, Peltzer,这与光合作用受到的气孔限制较小一致, Skelton,这表明非本土种群对非生物胁迫的反应存在根本性差异, Moyano, lower 13C values and higher stem growth rates all point towards higher net carbon assimilation by conifers in non-native ranges. This paradoxical combination of high growth rates yet resilience to drought emphasizes the importance of integrating eco-evolutionary history into ecological theory and is relevant for assessing the ultimate role of afforestation as global carbon sinks.
