Sentence examples for environmental breadth from inspiring English sources

Moreover, because populations of many wild relatives are under threat from habitat loss and degradation, there is an urgent need to collect and conserve crop wild relatives (CWRs) and to do so using methods that maximize genetic and environmental breadth.

Implicit in the effort to collect the environmental breadth of chickpea's wild progenitors are the idealized assumptions that differing environments will harbor locally optimal genotypes, and that some of the corresponding phenotypes will have utility for crop improvement.

Partial correlations were used to determine the relationship between geographic range and environmental breadth independent of sampling effort.

Not surprisingly, the partial correlations reduced the strength of the relationship between geographic range size and environmental breadth.

Our hypothesis that cosmopolitan genera have wider environmental breadth is also supported by a stronger positive relationship between area and environments than is observed for endemics.

Although our results cannot speak to physiology directly, our findings suggest that difference in environmental breadth between endemic and cosmopolitan genera may be one explanation.

Specifically, genera that occur outside of the focal region are significantly longer lived and have larger geographic ranges and environmental breadths within the focal region than do their endemic counterparts, even after controlling for differences in sampling intensity.

This may be due to factors such as niche breadth, environmental heterogeneity, dispersal, and immigration differing in importance among the two environments.

Environmental or niche breadth is one property that likely holds explanatory power.

A range of ecological and evolutionary explanations have been suggested for the observed range size variation, based on differences in niche breadth or environmental tolerance, body size, population abundance, latitude, environmental variability, colonization and extinction dynamics, and dispersal ability [ 3, 6- 8].

Given the breadth of environmental benefits oysters provide, as well as their commercial and cultural importance, sustainable oyster production has become a priority in several regions, including the Chesapeake Bay.
