Many aquatic (water dwelling) and some terrestrial (land dwelling) species use hydrochory, or seed dispersal through water. Seeds can travel for extremely long distances, depending on the specific mode of water dispersal; this especially applies to fruits which are waterproof and float on water. The water lily is an example of such a plant.
Drift seeds (also sea beans) and drift fruits are seeds and fruits adapted for long-distance dispersal by water. Most are produced by tropical trees, and they can be found on distant beaches after drifting thousands of miles through ocean currents .
Afzelia africana seeds bearing elaiosomes Chelidonium majus diaspores consisting of hard-coated seeds and attached elaiosomes. Myrmecochory (/ m ɜːr m ɪ ˈ k ɒ k ɔː r i / (sometimes myrmechory); [1] from Ancient Greek: μύρμηξ, romanized: mýrmēks ("ant") and χορεία khoreíā ("circular dance") is seed dispersal by ants, an ecologically significant ant–plant interaction ...
The patterns of seed dispersal are determined in large part by the specific dispersal mechanism, and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals.
Hydrochory is seed dispersal by water. [13] Seeds can disperse by rain or ice or be submerged in water. Seeds dispersed by water need to have the ability to float and resist water damage. They often have hairs to assist with enlargement and floating. More features that cause floating are air space, lightweight tissues and corky tissues.
Hydrochory is dispersal using water, including oceans, rivers, streams, and rain. [26] It affects many different dispersal units, such as seeds, fern spores, zooplankton, and plankton. Water sources surrounded by land tend to be more restricted in their ability to disperse units. [27]
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 ...
A diaspore of seed(s) plus fruit is common in plants dispersed by frugivores. Fruit-eating bats typically carry the diaspore to a favorite perch, where they eat the fruit and discard the seed. Fruit-eating birds typically swallow small seeds but, like bats, may carry larger seeded fruits to a perch where they eat the fruit and discard the seed.
