Interestingly, the population CUM, (ca. 1 km distance from CC which was sampled in 2011), clusters with a more distant population PER, which was sampled during the same season as CUM, 10 years after the first three populations were sampled.
And although differences in morphological characters between species are well defined (see below), testing for morphological intermediacy in individuals in adjacent versus distant populations will help distinguish between genetic similarity due to recent speciation or similarity as a result of secondary contact and hybridization.
Reply: Authors agree with the referee, the thermoreegulatory strategy description is bassed mainly on limited number of studies performed in Czech republic and in Finland (49. Frouz J, Finer L: Diurnal and seasonal fluctuations in wood ant (Formica polyctena) nest temperature in two geographically distant populations along a south-north gradient.
Salkin felt its importance lay not in its horticultural potential but in its appearance in two geographically distant populations.
Interestingly, the organisms in distant populations of a ring species have different reproductive mechanisms (Mayr 1963, 512ff).. Suppose Joe is a member of a ring species.
In comparison with CRISPRs in the ocean metagenome [ 26], the human gut appeared to be a more homogeneous environment as some spacers have protospacers in geographically distant populations.
Characterization of the SSR loci was estimated in two distant populations in China (Bosten Lake population and Liangzi Lake population; Appendix 1), each with 20 individuals.
We plan to test this idea in the future by analyzing genetic diversity in more distant populations from all along the Río Grijalva drainage system.
Recent introductions were typified by the existence of closely-related haplotypes in geographically distant populations, which is difficult to detect in most of Europe because of a lack of overall genetic structure.
These observations suggest that recent gene flow, or presence of the same alleles in the ancestral epigean forms that originally colonized the three cave populations, may explain why the same alleles are observed in geographically distant populations.
