蚂蚁传播种子，称为蚁播，在各种植物类群中普遍观察到。这些植物的种子有吸引蚂蚁的弹性体。在日本，人们对几种低地植物物种的蚁群分布进行了深入研究，但对生长在树线以上的高地植物物种的研究却没有。我们调查了在日本被称为“高山植物皇后”的荷包牡丹（Dicentra peregrina）的种子是否被2510 m a.s.l.的Formica gagatoidesants携带。在日本北阿尔卑斯山的纪仓山上我们观察到F.gagatoides工蚁通过抓住种子体并将种子带入巢穴来拾取D.peregrinaseeds。根据蚂蚁行为和种子形态的观察，我们推测，杜父蚁是一种蚁媒传播的物种。
Seed dispersal by ants, known as myrmecochory, is commonly observed among various plant taxa. The seeds of these plants have an elaiosome to attract ants. In Japan, myrmecochory has been well studied in several lowland plant species, but not in highland plant species that grow above the tree line. We investigated whether the seeds ofDicentra peregrina, known as the “queen of the alpine plants” in Japan, are carried byFormica gagatoidesants at 2510 m a.s.l. on Mt Norikura, Kita‐Alps, Japan. We observedF. gagatoidesworkers picking upD. peregrinaseeds by grasping the elaiosome and carrying the seeds into their nests. We inferred from the observed ant behavior and the seed morphology thatD. peregrinais a myrmecochorous species.
