However removing the introduced birds is difficult due to their inaccessibility to humans and high dispersal ability.

The expansion of these populations was then dictated by the dispersal ability of the population.

This group tested the effect of dispersal ability on predator-prey population dynamics.

Thus, species with greater dispersal ability may in fact have lower speciation rates.

Researchers have shown that body size and dispersal ability do not correlate (Jenkins et al. 2007).

They attributed this to better dispersal ability by smaller organisms, which may result in high distributions globally.

Its dispersal ability is one of the key factors that have allowed P. pinaster to become such a successful invasive species.

This may limit its dispersal ability, making it particularly vulnerable to habitat fragmentation.

Most invasive species tend to be r-selected individuals because of their high growth rate and dispersal ability.

The quality of the matrix surrounding a particular habitat fragment often makes a difference on a species' dispersal ability (Davis et al. 2007).
