Humans fundamentally affect dispersal, directly by transporting individuals and indirectly by altering landscapes and natural vectors. This human-mediated dispersal (HMD) modifies long-distance dispersal, changes dispersal paths, and overall benefits certain species or genotypes while disadvantaging others.

What is the role of man in seed dispersal?
Humans are known for their capacity to disperse organisms long distances. Long-distance dispersal can be important for species threatened by habitat destruction, but research into human-mediated dispersal is often focused upon few and/or invasive species. ... Average potential dispersal distances were measured at 13 km.
What is the role of human being in the dispersal of fruits and seeds?
Humans also play a big role in dispersing seeds when they carry fruits to new places and throw away the inedible part that contains the seeds. All of the above mechanisms allow for seeds to be dispersed through space, much like an animal's offspring can move to a new location.
How is a human dispersed?
Human-vectored dispersal (HVD) occurs when humans transport organisms directly. ... However, organisms can also be dispersed passively by abiotic or biotic vectors, such as animals, wind, or water. In this case, dispersal is determined by traits that affect uptake by the vector and survival during transport.
What is the purpose of dispersal?
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
