説明
<p>The aquatic beetle Cybister rugosus has experienced ongoing habitat loss, a decline in population numbers, and confirmed extinctions among insular populations in Japan, it has recently been listed on the Red List as endangered by the Japanese Ministry of Environment and has been designated a specified class II nationally rare species of wild fauna and flora. To design effective conservation strategies for this species, it is essential to compile data on its genetic variation to ascertain its genetic diversity and population structure. However, studies on the COI gene revealed low levels of genetic variation among Japanese insular populations and failed to detect a fine population structure. Then, we developed ten novel microsatellite markers for C. rugosus, using whole genome shotgun sequencing. The degree of polymorphism for these markers was further characterized using summary statistics describing the genetic variation in 49 individuals from the populations in Cambodia and on the islands of the Ryukyu Archipelago. Microsatellite data indicated differentiation among the insular populations in Japan, which could not be clearly shown in the COI data, and some insular populations showed low levels of genetic diversity. The newly developed microsatellite markers will contribute to future ecological or evolutionary studies on this species and conservation research.</p>
