Ants and Plants

(a Mutualism)

Naturalists spend much time being botanists or zoologists or perhaps just "birders" or "mushroom specialists". Often overlooked are the fascinating ways in which plants and animals inter-relate in what are sometimes called mutualisms (i.e. relationships that benefit two or more participating species). One mutualism relates ants to plants in an important way — ants gain food, plants gain a means of dispersal. The seeds of some of our native and introduced plants have, attached to their seed coat, small food bodies called elaiosomes. They are usually rich in fats but are now known to contain other compounds such as sugars, amino acids and aromatic substances. As seeds fall to the ground ants and possibly other organisms take them to crevices and nests, consume the food body but leave viable seed in sites where they may germinate. The dispersal mechanism was recognized as significant by

Sernander in 1906. The phenomenon of ant-mediated dispersal of seeds has been termed myrmecochory. More study of the phenomenon is warranted.


Other organisms "eat" elaiosome-bearing seeds — rodents, birds, slugs, insects. Some elaiosomes appear to produce aromatics and therefore may be attractants. Thus far however only ants are known to have a truly mutualistic relationship with elaiosome-bearing seeds. Recently we looked on the forest floor in Pacific Spirit Park (Vancouver BC) for plants which have seeds with elaiosomes. Several species were found to possess them including the native Pacific bleeding heart (Dicentra formosa), Siberian spring beauty (Claytonia sibirica), violets (Viola spp.), wild ginger (Asarum caudatum) and trillium (Trillium ovatum), and the European shrub Scotch Broom (Cytisus scoparius). A scanning electron micrograph of a seed of Dicentra from the park shows a food body on the seed coat.


Mutualisms are attracting more attention (1,2). The authors would encourage naturalists to collect native plant seeds, to examine them for elaiosomes and to search for evidence of mutualisms. Elaiosomes appear to us as very beautiful in form, even under a hand lens.

Elaiosomes are characteristic of many species but seem to occur rather randomly within genera and families. They are found in grass, sedge, legume, aster, borage and mint families, to name a few, and in a wide range of habitats.
