Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
Ants disperse seeds in fairly predictable ways, either by disposing of them in underground middens or by ejecting them from the nest. [2] These patterns of ant dispersal are predictable enough to permit plants to manipulate animal behaviour and influence seed fate, [13] effectively directing the dispersal of seeds to desirable sites. For ...
Pogonomyrmex badius workers transporting a seed to add to their granary Messor sp. carrying seeds into their nest. Harvester ant is a common name for any of the species or genera of ants that collect seeds (called seed predation), or mushrooms as in the case of Euprenolepis procera, which are stored in the nest in communal chambers called granaries.

Epilobium hirsutum — Seed head. In the broadest sense, dispersal occurs when the fitness benefits of moving outweigh the costs. There are a number of benefits to dispersal such as locating new resources, escaping unfavorable conditions, avoiding competing with siblings, and avoiding breeding with closely related individuals which could lead to inbreeding depression.
The ripe pods are brown and cacao-flavored, and fall to the ground over the space of a month. Though many wild animals eat the pods' flesh, only tapirs are large enough to swallow and disperse the seeds. The pods are eaten and dispersed with ease by domestic horses and cattle, making trees common in pastures or near them. [1] [4] [54]
A strawberry aggregate accessory fruit damaged by a mouse eating the seeds ().. Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source, [1] in many cases leaving the seeds damaged and not viable.
“For their size, chia seeds are very nutrient dense,” says Laura Iu, RD, a certified intuitive eating counselor, and owner of Laura iu Nutrition in New York City. In addition to omega-3s ...
Zoochory is the dispersal of seeds by animals and can be further divided into three classes. Endozoochory is seed dispersal by animal ingestion and defecation of a seed. In a mutualistic behavior, the animal is rewarded with nutritious fruit while harmlessly dispersing the seed or seeds, thereby increasing their fitness and chances for survival.
