To reassess the influence of the population structure, we used the Mantel test (zt software [ 53]) to evaluate the existence of isolation-by-distance in our dataset.
Genetic (ΦST values) and geographic distances (km) were significantly and positively correlated in the IRS1 (Mantel test, rp = 0.487, n = 13, p < 0.001) suggesting the existence of isolation-by-distance within IRS1.
In a grid connected PV system, the existence of galvanic isolation depends on the regulations of each country [38].
It is my hope that this article will partially fill the void of information that exists concerning the CMU, will help dispel rumors, and will inspire you to support those of us on the inside fighting the existence of these isolation units -- in the courts and in the realm of public opinion.
Furthermore, the presence of identical haplotypes in the analyzed mitogenomes adds further support to the existence of moderate isolation of Maya into relatively small consanguineous groups.
The nuclear genomes of the two clusters remained distinct in sympatry, particularly at three syntopic sites, suggesting the existence of reproductive isolation between the identified clusters.
We show, for example, that the number, size, and dynamics of modes in the distributions of the pairwise nucleotide differences in populations are informative on the existence of past isolation.
Since few crossings of deer with distinct karyotypes were obtained from the same chromosomal lineage (one female; H5), it is difficult to prove the existence of reproductive isolation within chromosome lineages, despite the fact that the hind produced was subfertile.
The mitochondrial DNA is regarded as fast evolving, but its mode of maternal inheritance can only reveal the presence of divergent lineages and cannot confirm the existence of reproductive isolation between lineages.
A larger sample must be collected, and more studies, particularly concerning the existence of reproductive isolation among closely related cytotypes must be performed so that the correct management and conservation decisions can be made.
However, a recent study that used a set of microsatellite loci to study pairs of populations distributed across the natural range suggested the existence of reproductive isolation rather than high rates of gene flow between Q. robur and Q. petraea [ 14].
