WebPassive Dispersal by Parasitic Stages. Parasitic stages are important for dispersal because usually the host can move much greater distances than the parasite would, even if the parasite has a motile stage. This type of dispersal is passive on the part of the parasite, and is successful only if the host is fed upon by another suitable host. ... WebJun 30, 2024 · By contrast, passive directed dispersal occurs when the donor plant takes advantage of vector behaviour to arrive at favourable microsites. Whereas predictable post-removal vector behaviour is dictated by characteristics of the donor plant in active directed dispersal, characteristics of the destination dictate predictable post-removal vector ...

WebJan 26, 2024 · Dispersal is one of the key processes determining biodiversity. The passive sampling hypothesis, which emphasizes dispersal processes, suggests that larger habitats receive more species from the species pool as the main mechanism leading to more species in larger habitats than in smaller habitats (i.e., species-area relationships).

WebDispersal over thousands of kilometres would require that propagules travel via high altitude winds and so be subject to low temperatures, dryness and high levels of UV radiation. Finally, regardless of how far a propagule is carried, it must land in a suitable habitat and there be able to overcome any competitors or predators.
