ABSTRACT

Biodiversity has been declining and extinction rates have been exponentially increasing because of land use changes, invasion of exotic species, nutrient enrichment and climate change. In this scenario, many international networks such as the International Union for the Conservation of Nature have been making efforts to raise conservation awareness and preserve species and their habitats in many countries. The relict longhorn beetle Callipogon relictus Semenov, 1899 (Coleoptera: Cerambycidae) is the largest coleopteran species in the Palearctic region and has a unique distribution compared to its congeneric species. Callipogon relictus has been protected by two Korean laws since it was designated as a Korean Natural Monument and an Endangered Species in 1968 and 2012, respectively. To improve the conservation of this species, ecological and biological data were obtained from studies performed during the last 12 years on its populations in Gwangneung Forest, the fourth UNESCO biosphere reserve in South Korea. Previously scattered distribution records of C. relictus from South Korea from 1932 to 2007 are therefore summarized and ecological features of adults observed during fields studies performed from 2008 to 2019 are presented. Based on the summarized data, we suggest different management measures and conservation efforts to maintain the size of C. relictus populations in South Korea, which can also be further used in the restoration of other endangered insects.

ABSTRACT

We estimated the genome size of a relict longhorn beetle, Callipogon relictus Semenov (Cerambycidae: Prioninae)-the Korean natural monument no. 218 and a Class I endangered species-using a combination of flow cytometry and k-mer analysis. The two independent methods enabled accurate estimation of the genome size in Cerambycidae for the first time. The genome size of C. relictus was 1.8 ± 0.2 Gb, representing one of the largest cerambycid genomes studied to date. An accurate estimation of genome size of a critically endangered longhorned beetle is a major milestone in our understanding and characterization of the C. relictus genome. Ultimately, the findings provide useful insight into insect genomics and genome size evolution, particularly among beetles.

ABSTRACT

An investigation on the habitation of Callipogonrelictus Semenov, 1899 in Gwangneung forest was carried out, where the Korea National Arboretum is located. In an investigation spanning the last eleven years (2007-2017), 22 emergence holes, nine pupal chambers, six adults, and two larvae of C.relictus were identified. In this study, biological information about habitation of C.relictus is provided by comparing and combining the results of this investigation with a survey conducted in Ussurisky Nature Reserve, Russia, in 2015. The distribution is also reviewed to include the Korean Peninsula and a new location of South Korea is added to the distribution for C.relictus.
