We have conducted a verification test of correlation between bird community indices and bird sound recording results in order to use the equipment which deals with the automatic sound collecting system, the song meter. The study areas include four sites which are Gombaeryoung and Zochimryoung in Jeombongsan Mountain and Jookryoung and Gochiryoung in Sobaeksan National Park. We collected the bird sound data five times using a sound recorder and field survey results in the same place of the study site. As a result of the sound recording from the field survey, the species recorded by three researchers of sound analyst include common resident species or species which have a relatively conspicuous call and song. On the contrary, the species recorded by only one researcher are a relatively rare or inconspicuous species or was familiar with the personal experiences of each researcher. The number of species recorded by only one researcher totaled fourteen species (36.8 %), and that of two researchers totaled twelve species (31.6 %), and that of three researchers totaled twelve species (31.6 %). The correlations of the number of species among three researchers was not significant in some results, but the sum or maximum count of the number of species was useful to estimate a significant correlation between the result of researchers and the indices of field surveys. As a result of correlation analysis by using sound recordings, the maximum number of species among the three researchers significantly correlated with the number of species, the species diversity index and the species abundance index in the field survey at the same site, however it did not correlate with the number of individuals and species evenness index. As a result of sound analysis collected from the stationary sound recording system; song meter, the number of frequencies in bird songs and calls correlated with the number of species in the field survey at the same site. The number of calls and songs decreased as time went by. Finally, we could test the active time range and change the activity strength by using a sound recording system. In particular, that sound recording system is able to collect data in same time and site, so it is expected so that the equipment not only replenish a shortage of researchers and survey periods in field research in a short term monitoring survey, but also be able to acquire statistical objectivity.

Recent herbarium reexamination and field studies yielded two monocotyledonous plant taxa of the family Poaceae that could be documented in the national inventory list of species of Korea. These species, collected from Jeollabuk-do and Gyeongsangnam-do, were introduced and naturalized in Korea. Two species were identified as Holcus mollis L. and Aira elegantissima Schur. We provided the descriptions and descriptive photos of these species. Keys to the newly recorded species and related taxa were also provided.

This study reports three species in the genus Tubastraea from Korea: Tubastraea coccinea Lesson, 1829; Tubastraea faulkneri Wells, 1982; and Tubastraea micranthus (Ehrenberg, 1834). Tubastraea faulkneri and T. micranthus are newly recorded in Korea. The specimens of three species were collected in the subtidal zones off Jeju-do between 1991 and 2010. The two newly recorded species were described in detail based upon the morphological characters of skeletal structures. The previous records of T. coccinea in Korea were supplemented with additional data in the remarks. These three species have a straight septal arrangement or irregular septal fusion in common as a main character for the genus Tubastraea, but they differ with respect to the growth form, intercorallite distance, exsertness from common coenosteum, and the detailed characters of septal arrangement. Tubastraea faulkneri is similar to T. coccinea in its plocoid growth form, well developed common coenosteum, and corallite size. However, unlike the latter species, the former species is characterized by rare or absent budding adjacent to the corallite edges, wider intercorallite distance, and irregularly developed septal fusion near the columella. In particular, T. micranthus is distinguished by an axial dendroid growth form, and the smallest corallites in this genus.
