Animals can disperse plant seeds in several ways, all named zoochory. Seeds can be transported on the outside of vertebrate animals (mostly mammals), a process known as epizoochory. Plant species transported externally by animals can have a variety of adaptations for dispersal, including adhesive mucus, and a variety of hooks, spines and barbs ...
Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. 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 ...
“It is a new idea that optimal seed dispersal is not only about building the greatest pressure in the fruit,” said Dr. Angela Hay, a research group leader at the Max Planck Institute for Plant ...
Dandelion seeds are adapted to wind dispersal. A dispersal vector is an agent of biological dispersal that moves a dispersal unit, or organism, away from its birth population to another location or population in which the individual will reproduce. [1] [2] These dispersal units can range from pollen to seeds to fungi to entire organisms.
Ants disperse seeds in fairly predictable ways, either by disposing of them in underground middens or by ejecting them from the nest. [2] These patterns of ant dispersal are predictable enough to permit plants to manipulate animal behaviour and influence seed fate, [13] effectively directing the dispersal of seeds to desirable sites. For ...
A bur (also spelled burr) [1] is a seed or dry fruit or infructescence that has hooks or teeth. The main function of the bur is to spread the seeds of the bur plant, often through epizoochory. The hooks of the bur are used to latch onto fur or fabric, enabling the bur – which contain seeds – to be transported to another location for ...
Diplochory, also known as “secondary dispersal”, “indirect dispersal” or "two-phase dispersal", is a seed dispersal mechanism in which a plant's seed is moved sequentially by more than one dispersal mechanism or vector. [1]
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.
