“…For severely endangered species that have only a few individuals remaining, an optimal strategy could be "complete genotyping (or ubiquitous genotyping)," that is, genotyping all individuals. An ongoing and successful example of this approach is the program in Japan where all individuals of more than 20 critically endangered plant species have been recorded and genotyped with microsatellite markers (Isagi & Kaneko, 2014). For larger populations, the minimum strategy should be to obtain good estimates of allele frequencies, for which sample sizes of 30-50 are typically sufficient (Dale & Fortin, 2014;Nei, 1978) and individual-level data are unnecessary, such as in Poolseq (Futschik & Schlotterer, 2010).…”

Intraspecific variation is a major component of biodiversity, yet it has received relatively little attention from governmental and nongovernmental organizations, especially with regard to conservation plans and the management of wild species. This omission is ill‐advised because phenotypic and genetic variations within and among populations can have dramatic effects on ecological and evolutionary processes, including responses to environmental change, the maintenance of species diversity, and ecological stability and resilience. At the same time, environmental changes associated with many human activities, such as land use and climate change, have dramatic and often negative impacts on intraspecific variation. We argue for the need for local, regional, and global programs to monitor intraspecific genetic variation. We suggest that such monitoring should include two main strategies: (i) intensive monitoring of multiple types of genetic variation in selected species and (ii) broad‐brush modeling for representative species for predicting changes in variation as a function of changes in population size and range extent. Overall, we call for collaborative efforts to initiate the urgently needed monitoring of intraspecific variation.

“…There is no appropriate approach that can examine the man-introduced origin hypothesis based on present study. However, a genetic analysis about "Endangered" species suspected of man-introduced origin also reported the quite low genetic variation (Isagi and Kaneko, 2014;Kaneko et al, 2017). The results of these previous studies are similar in the current genetic status of Korean H. luteovenosa population and might support man-introduced origin hypothesis.…”

“…Many endangered species have small population sizes, sometimes, in extreme situations, with less than 10 remaining individuals (Li et al, 2012;Choi et al, 2013). Understanding the genetic and ecological characteristics of endangered plants or populations is important for the examination of the origin and conservation value (Isagi and Kaneko, 2014;Shiga et al, 2017) and development of effective conservation management programs (Izuno et al, 2012;Choi et al, 2013;Kaneko et al, 2013). The consequences of a small population size have received considerable research attention in the past decades (Ouborg et al, 2006;Li et al, 2012;Choi et al, 2013;Kaneko et al, 2013).…”

The population status of Hydrangea luteovenosa Koidz. in Korea was investigated, with an emphasis on its genetic diversity. From field surveys, we obtained the only locality record for a wild population in Jeju Island, which contained 285 individuals in total. Genotyping was performed using five microsatellite markers for the all extant plants in Korea. Three Japanese populations were also genotyped for the comparative analyses. The genotyping result showed that the Jeju population consisted of only two multilocus genotypes, including identical heterozygous genotypes at two loci; it had been maintained mostly by vegetative reproduction; and although the Jeju population is geographically far from Japanese populations, all alleles observed in the Korean population were shared with Japanese populations, suggesting the possibility that H. luteovenosa in the Jeju Island had been recently migrated or introduced from Japan. Future ecological and genetic studies associated with negative effects of low genetic variation will be essential for determining the conservation direction of the threatened Korean population of this species.
