Sentence examples for level of dispersal from inspiring English sources

We found a pronounced difference in the evolved level of dispersal for certain combinations of local extinction and dispersal cost.

This low level of dispersal has led to genetic divergence across its range.

Nonetheless, the interactions between ecology, geography and social context on mating isolation detected here highlight the importance of expanding the predictions of speciation models to incorporate detailed investigations of the phylogenetic history, current ecological differences, and the level of dispersal between populations.

We would note that even though evidence suggests that most plethodontids will be limited in their ability to disperse northward under a warming climate, our study allowed for an optimistic level of dispersal that was still not sufficient to prevent significant declines in most species.

Consistent with this, the high level of dispersal among young males in house mouse populations [31] will have a general effect of separating close relatives of the opposite sex, reducing inbreeding even between pairs that do not share MUP type.

Theoretically, in the simplest scenario, these two factors exactly cancel each other out, such that the level of dispersal has no effect of the evolution of altruism (Taylor 1992).

High levels of dispersal, associated with interbasinal invasions, reduced opportunities for allopatric speciation.

A second important conclusion is that larger levels of dispersal can have very contrasted effects depending on the composition of the host community in the area of lower intrinsic transmission.

We show at first that weak levels of dispersal are associated with a reduction in infection as vectors infected in habitats of high transmission tend to spread into habitats with fewer hosts.

However, dispersal is a double-edged sword because too much can homogenize genetic variation across all populations, reducing the benefits of dispersal, and causing the rate of coevolution to drop off at very high levels of dispersal (Vogwill et al. 2008).

Zebra sharks are highly susceptible to localized depletion due to their shallow habitat and low levels of dispersal between populations, and market surveys suggest that they are much less common now than in the past.
