Pinus uncinata is the major treeline‐forming species in the Pyrenees. Yet, the role of its reproduction and dispersal as drivers of treeline dynamics remains unknown. Here we quantify seed production, dispersal and germination changes along the elevation gradient to assess whether they may constrain the foreseen treeline advance in the Pyrenees.

比利牛斯山的种子生产和传播限制树线进展

松林是比利牛斯山脉的主要树种。然而，其繁殖和传播作为树线动力学驱动力的作用仍然未知。在这里，我们量化了沿海拔梯度的种子生产，散布和发芽变化，以评估它们是否可能限制比利牛斯山脉中预见的林木行进。
