My Flashcards

Definition

Meaning

The dispersal of seeds by ants.

A specific form of seed dispersal in which ants carry seeds to their nests, often because the seeds possess a lipid-rich appendage called an elaiosome that attracts the ants. The ants consume the elaiosome and discard the intact seed, effectively planting it.

Linguistics

Semantic Notes

The term is almost exclusively used in botany, ecology, and myrmecology (the study of ants). It denotes a specific, mutualistic ecological interaction.

Examples

By Part of Speech

adjective

British English

  • The violet is a myrmecochorous species.
  • They studied myrmecochorous adaptations.

American English

  • Trillium is a myrmecochorous plant.
  • The myrmecochorous relationship is highly specialized.

Examples

By CEFR Level

B1
  • Some forest plants use ants to move their seeds.
B2
  • Myrmecochory is a fascinating example of coevolution between plants and insects.
C1
  • The evolutionary success of many understorey herbs in temperate forests is attributed to myrmecochory, which ensures seeds are dispersed to nutrient-rich microsites.

Learning

Memory Aids

Mnemonic

Think: 'MYRMECology' (study of ants) + 'CHOREography' (a planned movement). Ants perform the choreography of moving seeds.

Conceptual Metaphor

ANTS AS GARDENERS / SEEDS AS REWARD-BEARING PACKAGES.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating as just 'расселение семян' (seed dispersal). The term is specific to ants. A closer translation is 'мирмекохория' (direct borrowing) or 'распространение семян муравьями'.

Common Mistakes

  • Mispronunciation (e.g., 'myr-me-CO-chory').
  • Confusing it with general 'zoochory' (animal dispersal).
  • Using it as a verb (e.g., 'The seed myrmecochoried'). The verb form is not standard.

FAQ

Frequently Asked Questions

It is a widespread dispersal mechanism, particularly in certain ecosystems like temperate deciduous forests and some arid zones, involving thousands of plant species globally.

Ants are attracted to and consume the lipid-rich elaiosome attached to the seed, which provides them with a valuable food source.

No, the standard term is a noun. The related adjective is 'myrmecochorous'. One would say 'seeds are dispersed by myrmecochory' or 'the plant is myrmecochorous'.

It is distinguished by the specific involvement of ants and the presence of an elaiosome on the seed. It typically results in short-distance dispersal to protected, nutrient-enriched nest sites.
