The Effect of Climate Change on Indicator Wetland Insects: Predicting the Current and Future Distribution of Two Giant Water Bugs (Hemiptera: Belostomatidae) in South Korea.

Giant water bugs (Hemiptera: Belostomatidae) are top predators in wetland ecosystems, serving as biological indicators of the health of lentic ecosystems and as effective biological control agents for freshwater snails and mosquitoes. This study aimed to predict the current and future distribution of two Korean giant water bugs, and , under three climate change scenarios, contributing to the sustainable management of wetland ecosystems in South Korea. Using MaxEnt models, we employed seven climatic and three non-climatic variables to investigate the habitat preferences and distribution patterns of the species.

Genetic Attributes and Conservation of an Endangered Giant Water Bug Species, Miyamoto and Lee, 1966 (Hemiptera: Belostomatidae).

, a water bug from the family Belostomatidae, plays an important role in freshwater ecosystems as one of the top predators. In this study, we investigated the genetic diversity and population structure of by analyzing 318 specimens across 27 sites in South Korea. We found that the populations of possess 11 haplotypes with a haplotype diversity of 0.

A new species of genus Mulsant, 1842 (Scarabaeidae, Aphodiinae, Aphodiini) from South Korea.

A new species of the genus Mulsant, 1842, from South Korea, is described and illustrated on the basis of morphology and mitochondrial sequences. The species was compared with four related species; (Waterhouse, 1875), (Petrovitz, 1958), (Fabricius, 1775), and (Nomura & Nakane, 1951). The taxonomic status and diagnostic characters of the new species are discussed.

Climate change will lead to range shifts and genetic diversity losses of dung beetles in the Gobi Desert and Mongolian Steppe.

Desertification is known to be a major threat to biodiversity, yet our understanding of the consequent decline in biodiversity remains insufficient. Here, we predicted climate change-induced range shifts and genetic diversity losses in three model dung beetles: Colobopterus erraticus, Cheironitis eumenes, and Gymnopleurus mopsus, distributed across the Gobi Desert and Mongolian Steppe, areas known for desertification. Phylogeographic analyses of mitochondrial COI sequences and species distribution modeling, based on extensive field investigations spanning 14 years, were performed.
