抽象。从俄罗斯东北部的苔原（64-70°N）到俄罗斯东部和韩国的温带类型，再到日本南部小笠原群岛（26-27°N）的亚热带植被，沿沿着梯度，在当地社区和区域植物区系中评估了具有花外蜜腺的土著植物的发生和丰度。从苔原到亚热带植被，有一个模式，增加丰富的extrafloral轴承植物的功能，总的植物覆盖（从10.25%到40.18%），每采样面积的物种数（从0.11到1.13/100米），和区域植物区系内的物种比例（从0.32%到7.46%）。所有群落中都有部分植物具有花外蜜腺，但蜜腺的数量差异很大。在北方四个纬度和c. 7-70%在亚热带地区。蚂蚁，与植物花外蜜腺相关的主要互利者，具有相似的模式，沿着相同的南北纬度梯度增加丰富度（物种丰富度，巢密度和殖民地规模）。
Abstract. The occurrence and abundance of indigenous plants with extrafloral nectaries was evaluated within local communities and regional floras along a north to south gradient from tundra in northeastern Russia (64–70°N) through temperate types in eastern Russia and Korea to subtropical vegetation in the Bonin Islands (26–27°N) south of Japan. Moving from tundra to subtropical vegetation, there is a pattern of increasing abundance of extrafloral bearing plants as a function of total plant cover (from 10.25 to 40.18%), number of species per sampled area (from 0.11 to 1.13/100 m), and proportion of species within regional floras (from 0.32 to 7.46%). There were some plants with extrafloral nectaries in all communities but their abundance varied greatly, c. 1–25% in the four northern latitudes and c. 7–70% in the subtropical region. Ants, the primary mutualists associated with plants bearing extrafloral nectaries, have a similar pattern of increasing abundance (species richness, nest density, and colony size) along the same north–south latitudinal gradient.
