  • Twenty-five nominal species of Korea stag beetles have been reported from Korea since Heyden (1887). As a result of the present study, seven species are synonymized and the following six species are excluded from Korean fauna because they have been misidentified: Aegus laevicollis, Platycerus delicatulus, P. acuticollis, Gnaphaloryx velutinus, Prismognathus angularis and Nipponodorcus montivagus. The two species, Dorcus taiwanicus and A. laevicollis are discovered newly. Therfore, Korean Lucanidae consists of 14 species of 10 genera.

  • The Conus Linnaeus, 1758 is a large genus of marine gastropod mollusks belonging to the family Conidae. The Conus species are mostly distributed in the tropical waters of the world, and they are especially abundant in the Indo-West Pacific region. To date, more than 600 species, most of which are predatory species, have been named worldwide in this genus and only six species have been recorded in the Korean waters. Conus sponsalis Hwass in Brugui$\grave{e}$re, 1792 was collected from Jeju Island and identified as a new Korean record. In this study, we report a description of the shell morphology of the species.

  • Drought alters soil microorganisms; however, it is still not clear how soil microbes respond to severe drought conditions. In this study, the responses of soil bacterial community to experimental drought in a coniferous stand were examined. Six $6m{\times}6m$ plots with three replicates of control and drought treatments were delimited. PCR amplification and Illumina sequencing were conducted for cluster analysis of soil bacterial community and species richness and species diversity was analyzed. Along the 393 days of simulated drought from July 2016 to October 2017, soil bacterial species diversity slightly increased whereas species richness decreased in both control and roof plots. Moreover, soil bacterial species richness more decreased in roof plots than in controls. Combining these results, soil bacterial activity might have been altered by simulated drought.

  • Ishizakiella supralittoralis (Schornikov, 1974) was collected from rock pools near Busan, South Korea, and is redescribed herein. It is the first record of this species from Korea, and also the first finding of a living population of Ishizakiella McKenzie & Sudijono, 1981 from the continental margins. Here we also comment on the diversity of Ishizakiella in Japan, possible existence of cryptic species, and provide a key to all six currently known species of this genus, including the two fossil ones.

  • According to the energy hypothesis, the energy input per unit area primarily determines species richness in regions of roughly equal area. Some energy-related ecological research included identification of major climatic variables to determine regional species richness. In this study, the local butterfly species richness was examined to find out whether weather variables affected the local distribution or abundance of butterfly populations. Butterfly monitoring data from May 2001 to April 2002 taken at Mt. Yudal, Mokpo, in the southwestern part of Korea, and six weather variables (monthly mean values of temperature, precipitation, evaporation, wind speed, air pressure, and sunlight) were analyzed. Multiple regression analysis showed that only temperature explained 80% and 70% of the variability of log-transformed number of species and individuals, respectively, indicating that temperature played an important role in local species richness. Furthermore, global warming could affect the abundance and distribution of butterflies regionally as well as locally.

  • Comparative morphology of winter buds of 16 species of gymnosperms which belong to six families and 13 genera was investigated. All the species examined except Taxaceae had bracts and ovuliferous scales in female buds, and the bract was fused with ovuliferous scale in various degrees. Comparison of the modern conifers with fossil ones in the position of ovule and structure of bract-scale complex suggested that Taxaceae should be placed in Coniferales, rather than treating as a distinct order. The disposition of bract surrounding the ovules of Cephalotaxus and Torreya indicated that the origin, of ovules had separate evolutionary line in spite of similar structure of female bud. The shape of microsporophyll in male bud was diverse among the species. The dehiscence of microsporangium was transverse in Abies and Tsuga, while longitudinal in other species. Descriptions and key to the species based on bud morphology were provided.

  • The patterns of serum proteins in seven species of Korean rodents were analyzed by immunoprecipitin, immunodiffusion, and immunoelectrophoresis. It is found that the serum proteins of each species were different with one another and thatntigenic divergence among the seven species seems to be enormous , ie., serological correspondence ranged from 99.6 in Rattus norvegicus caraco(suborder Myomorpha) to 2.7 in Tamias sibircus asiaticus (suborder sciuromorpha). In the six species of the family Muridae (Suborder Myomorpha), the lowest value of 8.2 was shown in Clethrionmys rufocanus regulus (Subfamily Microtinae).

  • Two shark species captured in Samcheok in 2006 and Ulsan in 2013, previously reported as Heptranchias perlo and Alopias pelagicus, were confirmed to in fact be Hexanchus griseus and A. superciliosus, respectively, neither of which has previously been reported in Korea. H. griseus has six gill slits and is thus distinguishable from Heptranchias perlo, which has seven gill slits. A. superciliosus is clearly distinguishable from A. pelagicus and A. vulpinus, members of the family Alopiidae, due to its large eyes and a groove extending from the center of the head to both eyes. The keys to the family Hexanchidae, including H. griseus, and the family Alopiidae, including A. superciliosus, were presented along with the morphological characteristics of these two new shark species. These two species were given the Korean names "Gi-reum-sang-eo" and "Keun-nun-hwan-do-sang-eo," with reference to their morphological characteristics and English names.

  • In 2021, during a survey of cnidarian fauna around Geomundo located in the Dadohaehaesang National Park in the South Sea, complete pinnated hydroid colonies attaching on vertical rocky surface at depth of 45 m were collected by SCUBA diving. Through taxonomic examination, unrecorded species, Sertularella acutidentata Billard, 1919, is newly added to the hydrozoan fauna of Korea. Recently, taxonomic position of the genus Sertularella has been relocated into the new family Sertularellidae Maronna et al., 2016 and six species from Korean waters have been synonymized or transferred to new genera. Thus, a total of 17 species belonging to genus Sertularella, including the species reported in this study, have been reported in Korean waters so far.
