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.
An example of the use of landscape genetics as a means to study seed dispersal, for example, involves studying the effects of traffic using motorway tunnels between inner cities and suburban area. [35] Genome wide SNP dataset and species distribution modelling are examples of computational methods used to examine different dispersal modes. [34]
Over 100 species of vascular plants use this dispersal method for their fruit. [26] Many plants have evolved with specific adaptations to maximize the distance that seeds, fruits, or propagules are dispersed in the ocean. To better protect them against sinking in the water column, some seeds have developed hair or slime on their outer seed ...
Longer dispersal distances and potentially larger ecological consequences follow from sequential endochory by two different animals, i.e. diploendozoochory: a primary disperser that initially consumes the seed, and a secondary, carnivorous animal that kills and eats the primary consumer along with the seeds in the prey's digestive tract, and ...
Plants are produced using material from a single parent and as such, there is no exchange of genetic material, therefore vegetative propagation methods almost always produce plants that are identical to the parent. In some plants, seeds can be produced without fertilization and the seeds contain only the genetic material of the parent plant.
In botany, a diaspore is a plant dispersal unit consisting of a seed or spore plus any additional tissues that assist dispersal. In some flowering plants, the diaspore is a seed and fruit together, or a seed and elaiosome. In a few plants, the diaspore is most or all of the plant, and is known as a tumbleweed. Diaspores are common in weedy and ...
She notes that different species may enjoy other types of seed as well. “Black oil sunflower seed is the number one feed to use in a feeder,” says Mike O’Connor, the owner of Bird Watcher ...
This type of seed dispersal is termed myrmecochory from the Greek "ant" (myrmex) and "circular dance" (khoreíā). This type of symbiotic relationship appears to be mutualistic , more specifically dispersive mutualism according to Ricklefs, R.E. (2001), as the plant benefits because its seeds are dispersed to favorable germination sites, and ...
