A problem with reconstructing historical geographic distributions based on current distributions is that the older a reconstruction, the less likely it is that the reconstructions are correct.
It is hypothesized that R. balteatus colonized the northernmost parts of its range (i.e., British Columbia) post-glacially from a refugium in the Upper Columbia River Basin based on current distributions above barrier falls and several known geomorphic connections [ 18, 19].
Therefore, in the absence of strong signal to support an alternative hypothesis and based on current taxonomic distribution of this character, we currently favour the null hypothesis that the folB-folK-folP three-domain gene fusion is monophyletic and arose once and before the diversification of the opisthokonts and amoebozoans.
Based on current oil and gas distribution, it is found that our evaluation results before and after improvement are significantly different.
Constraints included proximity restrictions (based on current ordinances regulating outlet distribution) of at least 200 feet between alcohol outlets and at least 300 feet between outlets and schools, churches, hospitals, parks and playgrounds.
We used a multivariate approach borrowed from paleoecology to quantify the potential change in California terrestrial breeding bird communities based on current and future species-distribution models for 60 focal species.
These analyses not only help to highlight the current distribution of chicken lineages in the Pacific, but also provide a framework for discussing the complications inherent in distinguishing prehistoric, historic, and recent commercial introductions and in inferring origins based on current lineage frequencies and distributions.
The latter result, which could neither be practically achieved in the controls nor expected based on current models of pore size distribution, demonstrated the greater openness of the pore structure of the bimodal material, which remarkably did not come at the expense of its mechanical properties.
The locations and times of these incidents are stochastic and must be modeled by an empirical distributions based on current incident data.
Besides, for the Corsican pine, data from current coppices apart from its current distribution in forests were available, so we also used one additional LPT, based on current coppice data (the lowest probability associated with the presence of a coppice).
