  • Severe fever with thrombocytopenia syndrome virus (SFTSV) is a zoonotic, tick-borne RNA virus of the genus Bandavirus (Family Phenuiviridae), mainly reported in China, Japan, and the Republic of Korea (Korea). For the purpose of this study, a total of 3,898 adult and nymphal ticks of species Haemaphysalis longicornis (94.2%), Haemaphysalis flava (5.0%), Ixodes nipponensis (0.8%), and 1 specimen of Ixodes ovatus, were collected from the Deogyusan National Park, Korea, between April 2016 and June 2018. A single-step reverse transcriptase-nested PCR was performed, targeting the S segment of the SFTSV RNA. Total infection rate (IR) of SFTSV in individual ticks was found to be 6.0%. Based on developmental stages, IR was 5.3% in adults and 6.0% in nymphs. The S segment sequences obtained from PCR were divided into 17 haplotypes. All haplotypes were phylogenetically clustered into clades B-2 and B-3, with 92.7% sequences in B-2 and 7.3% in B-3. These observations indicate that the Korean SFTSV strains were closer to the Japanese than the Chinese strains. Further epidemiological studies are necessary to better understand the characteristics of the Korean SFTSV and its transmission cycle in the ecosystem.

  • Over the last few years, an increased awareness of endocrine disrupting chemicals (EDCs) and their potential to affect wildlife and humans has produced a demand for practical screening methods to identify endocrine activity in a wild range of environmental and industrial chemicals. It is clear that in vivo methods will be required to identify adverse effects produced by these chemicals. (omitted)

  • Prunus speciosa (Koidz.) Nakai belonging to Prunoideae of Rosaceae, a species previously unrecorded in Korean flora, is described. Prunus speciosa (Koidz.) Nakai is similar to Prunus sargentii Rehder and Prunus jamasakura Siebold ex Koidz., but different because it has toothed lobes of calyx tubes with the apex of leaf serrations aristate. This species is naturalized widely in the eastern parts of Jeju Island but is endemic to Japan.

  • Sponges of the family Spongiidae are poorly known in Korean waters. This paper describes Hippospongia bergquistia n. sp. of the family Spongiidae (Demospongiae: Dictyoceratida) collected from Moselpo, Jejudo Island, Korea in 2007. This new species has a cavernous construction, rare pseudo-tertiary fibre, and rare primary fibres.

  • The report describes a case of natural E. ewingii infection confirmed by microscopic examination and molecular analyses in a domestic dog with acute lameness. After the diagnosis, the dog was successfully treated with oral doxycycline. To authors' knowledge, this is the first case report of natural E. ewingii infection in dogs in South Korea.

  • Persistent organic pollutants (POPs) have spread throughout the global environment to threaten human health and damage ecosystems. with evidence of POPs contamination in wildlife, human blood. and breast milk documented worldwide. Breast milk is an ideal medium for assessing exposures to POPs. POPs enter humans largely as contaminants of dietary animal products, where they sequester in adipose tissue, serum, and breast milk and equilibrate at similar levels on a fat weight basis.

  • Carbofuran(CF) is one the most widely used carbamate pesticides in the world applied for insect and nematode control. Due to its widespred use in agriculture and households, contamination of food, water, and air has become serious, and consequently adverse health effects are inevitable in humans, animals, wildlife and fish, it has reported that CF alone or in combination with other carbamate insecticides influences the level of reproductive and metabolic hormones such as thyroxine and corticosterone, and results in impairment of endocrine.

  • The adverse health effects on humans and domestic and wildlife species by exposing to environmental contaminants. which interact with the endocrine system. have he en treated as an important issue without hesitation throughout the 1990s. The chemicals with practical and/or potential interfering actions with the endocrine system functions are called endocrine disrupting chemicals (EDCs). (omitted)

  • Fairy Pittas use the forest around the valley and Gotjawal as breeding places. This survey was conducted to investigate the characteristic of earthworms, specifically its population density, body size around the breeding site in Gotjawal and the forest around the valley areas from the middle of July to the end of July 2013. A total of 405 individual earthworms were collected in the 100 small established quadrats, in which 315 were found in Gotjawal and 90 were found in the forest around the valley area. The density of earthworms in Gotjawal was significantly higher compared to that forest around the valley area. It was also observed that the body size of earthworms was significantly different between Gotjawal and the forest around the valley area. Proportion of number of individuals which are larger than 7cm in body size was 43%(n=135) in Gotjawal and 84%(n=76) in the forest around the valley area, respectively. Soil area was not important factor to the density of earthworms. We suggest that Gotjawal can be considered as a suitable breeding site for Fairy Pitta because of the richness of its primary food in this area.
