Sentence examples for distributional boundaries from inspiring English sources

Because of limited sampling, all but the most common species are known from small numbers of specimens, and the available specimens and distributional records are inadequate to determine taxonomic and distributional boundaries, especially for similar-looking species (or subspecies) that inhabit the same areas, so are frequently misidentified.

Consideration of M. namaquensis diversity within a biological species concept (BSC) framework would require accurate delineation of the distributional boundaries of the identified lineages and mapping of areas of overlap through further sampling and genetic analyses.

Rather than invoking unrealistic long-distance dispersal (e.g. [ 13]) or ecological niche shifts (e.g. [ 14]) to explain discordant genetic structure and predicted paleo-distributions, species may simply have persisted in scattered microrefugia that supported isolated, low-density populations beyond their inferred distributional boundaries during the Pleistocene [ 12].

The region separating the Piedmont from the Coastal Plain is the "fall line" and often forms the distributional boundary between many upland and lowland species.

For many other species whose range partially overlaps the CVT (e.g., Colomesus psittacus, Paralabrax dewegeri, and Genyatremus luteus), their western distributional limit coincides with the Santa Marta-La Guajira boundary, around the PNNT.

To derive existence and comparison results for extremal solutions of nonlinear singular distributional initial value problems and boundary value problems.

The convergence rates of both schemes are comparable, and the use of finite elements requires a parameterization of the boundary, while the wavelet-Galerkin method admits an implicit description of the boundary in terms of a wavelet representation of the boundary measure defined as the distributional gradient of the characteristic function of the interior.

We saw no significant hotspot distributional biases with respect to chromosomal arm/core boundaries (p-value 0.9618, Figures 2, 3 and 4).

This paper is devoted to the study of existence and dependence of solutions of the first-order periodic boundary value problems involving the distributional Henstock-Kurzweil integral.

In the present paper, we investigate the existence of solutions to second order nonlinear boundary value problems (BVPs) involving the distributional Henstock-Kurzweil integral.

Distributional information, by contrast, consists of "knowledge about the distribution of outcomes in similar situations".
