This conclusion is also consistent with the presence of several well-supported subclades that are comprised of specimens from a single geographic locality, or multiple geographically proximate localities (Fig. 4).
Similar to the clustering in the Pacific Northwest, in California, a main cluster was observed that showed some geographic substructure (i.e. geographically proximate populations tend to cluster more closely with each other).
We then compared these pairwise distances with the respective geographical distances to test if geographically proximate populations of the species differ more strongly in acoustic parameters than distant populations using Mantel correlation.
Genetic differentiation at neutral genetic markers is common in salmonids, including at small geographic scales (e.g., within large river systems, between geographically proximate lakes) (Taylor 1991; Garcia de Leaniz et al. 2007).
These emerging giants have also exploited similarities between geographically proximate developing markets to grow across borders.
They too have the ability to find like-minded people who may not be geographically proximate and can collaborate on collective political action.
The increase in different investment incentives is well documented, and it reflects more-intense competition, especially between similar and geographically proximate locations.
At the same time, similarly sized and geographically proximate cities (i.e., Mobile, AL and Nashville, TN) did not experience a comparable rise in property crime during this time.
China, India and Russia are all Asian powers, geographically proximate to Afghanistan and better able, therefore, to garner practical advantages from any stability our armed forces would make possible.
Even if our lives overlap, even if they are geographically proximate, the men who fathered our parents are often depleted or ill by the time we may question them.
The implicit assumption in these specifications is that geographically proximate areas provide better controls.
