Hydrochory

 

the dissemination of the fruits, seeds, and other primordia of plants by means of water currents. Hy-drochory is typical primarily for marsh and water plants, algae, and some kinds of fungi. The adaptations for this means of transmission are various bulges and growths on fruit membranes or seed coats (or special cells, as in the spores of fungi), which are filled with air and act as floating sacs. Plants in which hydrochory occurs include water plantain, arrowhead, flowering rush, bur reed, and pondweed.

Furthermore, this species has a peculiar type of hydrochory in addition to autochory.
For example, barochory (primary dispersal) could be followed by myrmecochory or hydrochory (secondary dispersal).
However, secondary amenochory and hydrochory cannot be ruled out from these accounts.
In order to evaluate the importance of ichthyochory and hydrochory in the seed dispersal process we compared the number of seedlings produced between the FMS and a soil seedbank study performed in the a neighboring area (Pagotto et al., 2011).
Hydrochory and regeneration in a bald cypress-water tupelo swamp forest.
Hydrochory is probably of neglectable importance, and ichthyochory is responsible for long distance dispersal helping to colonize new habitats.

Angiosperms have evolved a multitude of external dispersal adaptations, including wind (anemochory), water (hydrochory), animal (zoochory), and self-dispersal (autochory; Fenner, 1985).
Hydrochory is probably another important way of seed dispersal in riparian palms that often form oligarchic populations close to rivers and lakes (Goulding & Smith, 2007).
Fruits are relatively large (2 by 2.5 mm), corky, and buoyant (Affolter, 1985); thus, hydrochory is expected to be the main mechanism of dispersal.

Though thistles are usually wind- or animal-dispersed, clearly Cirsium vinaceum is capable of hydrochory. There are several cases of normally wind-dispersed species whose seeds travel effectively by water (e.g., Telenius and Torstensson, 1989; Thebaud and DeBussche, 1991).
