MYRMECOCHORY Meaning and
Definition
-
Myrmecochory is a biological process in which ants and plants have a mutualistic relationship for the dispersal of plant seeds. The term "myrmeco" refers to ants, and "chory" means dispersal. This phenomenon is a specialized seed dispersal mechanism facilitated by ants.
In myrmecochory, certain plant species develop small, nutrient-rich structures called elaiosomes attached to their seeds. These elaiosomes attract ants due to their high lipid content, serving as a food reward for the ants. The ants carry the seeds back to their nests, where they feed the elaiosomes to their larvae. Once the larvae consume the elaiosomes, the ants discard the seeds within nutrient-rich ant mounds or in their underground tunnels. This process offers mutual benefits for both the plants and the ants.
For the plants, myrmecochory promotes seed dispersal over short distances and facilitates seed germination in nutrient-rich microsites created by the ants. The ants benefit from the nutritious elaiosomes, providing food for their larvae. Additionally, some ant species use the seeds as a food source for themselves during times of scarcity.
Myrmecochory is an example of a specialized and intricate ecological interaction between ants and plants. It is particularly common in certain plant families, such as violets, bloodroot, and trilliums. This seed dispersal mechanism is ecologically significant as it allows plants to colonize new areas, maintain genetic diversity, and enhance their chances of survival. Overall, myrmecochory is a fascinating symbiotic relationship between ants and plants that plays a crucial role in the dynamics of ecosystems.
Etymology of MYRMECOCHORY
The word "myrmecochory" is derived from two Greek words: "myrmex" meaning "ant" and "khorein" meaning "to disperse" or "to spread". These components come together to create the term "myrmecochory", which refers to the process of seed dispersal by ants.
