Data from: The biogeography of sodium in Neotropical figs (Moraceae)

Sodium is essential for animals but not for most plants. Terrestrial sodium comes largely from marine aerosols, so inland ecosystems should have greater potential for sodium limitation than coastal ecosystems. We report a significant decrease of sodium in fruits of four Neotropical Ficus species with distance from presumed marine source.

钠（Sodium）为动物所必需的营养元素，但多数植物并不需要钠。陆地钠的主要来源为海洋气溶胶，因此内陆生态系统相较于沿海生态系统，更易出现钠限制现象。本研究发现，4种新热带区榕属（Ficus）植物的果实钠含量随其距推定海洋钠源的距离增加而显著降低。
