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.
Erythrina / ˌ ɛr ɪ ˈ θ r aɪ n ə / [4] is a genus of plants in the pea family, Fabaceae. It contains about 130 species , which are distributed in tropical and subtropical regions worldwide. They are trees , with the larger species growing up to 30 m (98 ft) in height.
No non-native species of Erythrina is known to be naturalized in Hawaiʻi. [4] The wiliwili is distinguished from the other seven cultivated species by a pod with only one to three red or yellow-orange seeds, which sink in water; [10] non-native Erythrina have pods with larger numbers of brown seeds, which float in water. [11]
Seeds have evolved traits to reward animals to enhance their dispersal abilities. [5] Differing foraging behaviours of animals can lead to selection of dispersal traits and spatial variation [3] [8] such as increase in seed size for mammal dispersal, which can limit seed production. [9]
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.
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 ...
Erythrina fusca is a species of flowering tree in the legume family, Fabaceae. It is known by many common names, including purple coraltree, gallito, bois immortelle, bucayo, and the more ambiguous "bucare" and "coral bean". E. fusca has the widest distribution of any Erythrina species; it is the only one found in both the New and Old World.
Erythrina herbacea, commonly known as the coral bean, Cherokee bean, Mamou plant in South Louisiana, red cardinal or cardinal spear, is a flowering shrub or small tree found throughout the southeastern United States and northeastern Mexico; [2] it has also been reported from parts of Central America and, as an introduced species, from Pakistan.
