Sentence examples for patchy populations from inspiring English sources

Spatially patchy populations present challenges for precise estimation of abundance from surveys, which typically result in high estimation errors compared to surveys of more evenly distributed species.

A convenient way to describe dispersal strategies between species is to distinguish patchy populations from metapopulations [ 11].

In addition, the species forms patchy populations on sandy soils (L. P. Queiroz, personal communication), which together with the pollinator behavior favors autogamy and low heterozygosity.

The pattern of spatio-temporal genetic changes found in our study can be compared to that of cyclic populations, where demographic crashes lead to a patchy population structure with local, isolated demes of small size experiencing strong effects of drift.

If true, this population genetic model would imply even stronger selection on leaf shape and life history traits, as they have diverged latitudinally while the patchy population genetic structure has remained intact.

Investigation of pollen-mediated genetic connectivity and variation in the mating system of rare species is readily achieved in the ancient landscape of south west Western Australia (WA) as it is rich in historically rare plant species with typically small population size and disjunct and patchy population distributions.

Its distribution is patchy, with populations often being isolated from each other.

However, benefits to cooperation may be offset by the increased competition generated between kin in patchy, unmixed populations (Griffin et al. 2004).

An elegant socio-ecological hypothesis on desert drivers contends that an unpredictable climate and scarce resources (low soil fertility) result in a sparse, mobile, and patchy human population.

The dolphin's range is patchy, with major populations around South America, southwestern Africa, New Zealand, and various oceanic islands, with some sightings around southern Australia and Tasmania.

The patchy distribution of populations of this symbiotic system should not only facilitate bottleneck effects, but also the appearance of a genetic pattern of IBD.
