Sentence examples for distribution dispersal from inspiring English sources

The genetic structure of aphid populations is shaped spatially and temporally by habitat distribution, dispersal capabilities, and life-cycle.

This suggests that in certain areas of the species distribution, dispersal via overland flight across drainage boundaries may be more common than dispersal via overland flight (or larval drift) between distant localities (100 500 km distant) on the same river.

A Laplacian statistical distribution (the dispersal kernel) predicted a mean dispersal distance of 13 19 km, with 90% of settlement occurring within 31 43 km.

Parameter A defines the distribution of dispersal differences, 1/A is the average dispersal distance, and Z is a shape parameter for the dispersal curve [ 50].

These methods produce estimates of migration rates (m) or moments of the distribution of dispersal distances (such as σ, the standard deviation of axial dispersal distances, Box 2) which can be difficult to interpret in an ecological context.

(2003) found a bimodal distribution of dispersal, with a range for long-distance dispersers on the order of 20 200 km/year.

(A) The distribution of dispersal distances can be estimated in two ways: through the direct detection of discrete dispersal events (blue bars), or the indirect estimation of dispersal parameters like the standard deviation of parent offspring dispersal distances.

Secondly, the frequency distribution of dispersal distances is highly skewed with the vast majority dispersing extremely low distances (Harrington et al. 2005).

The approach taken in this study generates information about the distribution and dispersal of a native invasive species and could potentially be used to help make management decisions and develop monitoring programs to control and reduce the expansion of native invasives.

Three well-known models were fitted to normalised frequency distribution of dispersal distances: the lognormal (LN), the inverse Gaussian (IG) and the Weibull (WB), as shown in the lower part of Table 1; however, not as part of eqn. (1) where only seed density vs. distance was modelled instead.

However, little is known about the distribution and dispersal ability of Polysiphonia species.
