Consequences of hydrochory in Hibiscus
Plant Species Biology, 2006Abstract Seed dispersal provides a template upon which the demographic processes of plant life cycles operate and, most importantly, seed dispersal determines the spatial distribution of genetic variation.

PROCESSES GOVERNING HYDROCHORY ALONG RIVERS: HYDRAULICS, HYDROLOGY, AND DISPERSAL PHENOLOGY
Ecological Applications, 2002Rivers are important corridors for movement, migration, and dispersal of aquatic organisms as well as for dispersal of the seeds and vegetative propagules of riparian plants. In this investigation, the relationships between flow regime, channel morphology, dispersal phenology, and seed deposition patterns were evaluated using experimentation in a flume.

Importance of hydrochory in structuring plant communities along rivers
Canadian Journal of Botany, 1991Using wooden cubes as experimental seed mimics we tested whether differences in seed deposition among riverbank sites predictably affect the structure of riparian vegetation. Although cube deposition was not interpretable in terms of environmental variables like current velocity, riverbank width, and substrate, it was related to species composition of

Ecohydrology, 2019
AbstractThe configuration of channels in stream networks is vital for their connectivity, biodiversity, and metacommunity dynamics. We compared the capacity of three process domains—lakes, slow‐flowing reaches, and rapids—to disperse and retain plant propagules by releasing small wooden cubes as propagule mimics during the spring flood and recording ...

Hydrochory and Regeneration in A Bald Cypress‐Water Tupelo Swamp Forest
Ecology, 1988The importance of hydrochory, or seed dispersal by water, to the regeneration of Taxodium distichum (bald cypress) and Nyssa aquatica (water tupelo) as examined in a forested floodplain of the Savannah River in South Carolina. Seedfall and dispersal by water were quantified for 2 yr using floating seed traps.

Effect of slope position on hydrochory processes: a natural rainfall study in tropical agroecosystem
2023Soil erosion due to land use change and consequently biodiversity loss are major concerns in agricultural areas. However, the link between runoff, soil loss and plant dispersion by water also called hydrochory is not yet well understood, especially in tropical climate.

Hydrochory, Population Dynamics and Distribution of the Clonal Aquatic Plant Ranunculus Lingua
The Journal of Ecology, 1993The dispersal and dynamics of the clonal aquatic plant Ranunculus Lingua were studied in a marginal river population in northern Sweden, where this species is dispersed exclusively by vegetative diaspores (i.e. floating rhizome fragments). The study focused on the extent and range of dispersal, relationships between dispersal and distribution of ...

Spatial and Temporal Variation in Hydrochory in Amazonian Floodplain Forest1
BIOTROPICA, 2002ABSTRACT The hypothesis that water depth, plant species, and the presence of submerged substrates influence seed dispersal by water was tested in a whitewater tributary of the Tocantins River of the Amazon Basin. Seed dispersal was greatest when water depth was greatest, which occurred during the new moon.
