Four feral cats and a raccoon dog purchased from a local collector on Aphaedo Island, Shinan-gun, where human Gymnophalloides seoi infections are known to be prevalent, were examined for their intestinal helminth parasites. From 2 of 4 cats, a total of 310 adult G. seoi specimens were recovered, Other helminths detected in cats included Heterophyes nocens (1,527 specimens), Pygidiopsis summa (131), Stictodora fuscata (4), Acanthotrema felis (2), Spirometra erinacei (15), toxocarids (4), and a hookworm (1). A raccoon dog was found to be infected with a species of echinostome (55), hook-worms (7), toxocarids (3), P. summa (3), and S. erinacei (1). No G. seoi was found in the raccoon dog. The results indicate that feral cats and raccoon dogs on Aphaedo are natural definitive hosts for intestinal trematodes and cestodes, including G. seoi, H. nocens, and S. erinacei, It has been first confirmed that cats, a mammalian species other than humans, play the role of a natural definitive host for G. seoi on Aphaedo Island.

We investigated vascular plants of Aphaedo Island in Shinan-gun, Jeollanam-do, Korea. By referring to voucher specimens collected over the course of 28 days from May of 2011 to March of 2016, a total of 451 taxa were identified and grouped into 102 families, 294 genera, 413 species, 6 subspecies, 30 varieties, and 2 forms, of which 9 taxa were classified as endangered or rare, including Albizia kalkora, Salomonia oblongifolia, and Centranthera cochinchinensis var. lutea. A total of 59 taxa were identified as regional indicator plants. Six taxa were endemic to Korea, including Hepatica insularis, Indigofera koreana, and Lespedeza maritima. Three taxa (Rumex acetosella, Aster pilosus, and Hypochaeris radicata) among 52 naturalized taxa were ecosystem-disturbing plants as designated by the Ministry of the Environment. The results of preceding floristic research before and after the inauguration of the Aphaedaegyo (bridge) were used to analyze changes in the number of naturalized species on Aphaedo Island.

We investigated the moth diversity on an island of southern sea of Korea. We collected moths at three sites on the island of Bogildo, Wando-gun, Jeonnam using a 22-watt ultraviolet light trap from May to October, 2008, and identified a total of 272 species and 948 individuals in 13 families. Species of Noctuidae was the most abundant, with 107 species and 318 individuals, followed by Geometridae (62 species and 147 individuals) and Pyralidae (53 species and 269 individuals). The graph of the estimated species richness in Chao 1 (432.25$\pm$37.39) did not reach an asymptote, which suggests that more moth species could be identified on the island through further sampling. An arctiid moth, Miltochrista striata, was the most abundant species captured in this study. Monthly changes in moth species richness and abundance formed M-shaped curves, with peaks in early summer (June) and late summer (August). Cluster analysis of seven sites on three islands (Aphaedo Island, Sinan-gun, Oenarodo Island, Goheung-gun and Bogildo Island) divided the sites into two groups. Distances among sites and habitat types may play an important role in determining the similarities of moth faunas among sites.
