Seed dispersal in myrmecochorous plants, in which a sequence of two or more steps is often involved, has profound effects on plant benefits. First, seeds mature or fall onto to the ground (primary dispersal), then ants transport them into nests (ant dispersal), and sometimes ants subsequently discard seeds out of nests (re-dispersal). By neglecting one or the other of these phases, we might misjudge the benefits of myrmecochory to plants. Here, we investigated the difference between two common Chinese myrmecochorous plants, Corydalis incisa and C. wilfordii, in the importance of each dispersal...
