seed dispersal
Quick Summary
Zoochory is a type of seed dispersal where plants are distributed by living animals. This process is crucial for plant reproduction and diversification.12
Types of Zoochory:
- Endozoochory: Animals consume seeds or fruits, which are then passed through their digestive system and dispersed in feces. This is a significant method of dispersal, and frugivory (fruit-eating) is thought to have evolved as a mutualistic strategy to facilitate seed dispersal.2
- Epizoochory: Seeds or diaspores (dispersal units) are accidentally carried on the outside of animals. This often involves burrlike seeds with hooks or spines that cling to fur.2
- Synzoochory: Animals intentionally carry seeds or diaspores, typically in their mouths. Birds caching nuts or dropping seeds are examples.345
Various animals, including mammals, birds, reptiles, fish, and even ants and earthworms, can act as zoochorous agents. This animal-mediated dispersal is vital for many plant species, especially in tropical ecosystems.265
