  • From April 2009 to October 2011, we surveyed the higher fungi in the Byeonsanbando National Park, Korea. In total, we identified 2 kingdoms, 3 divisions, 7 classes, 22 orders, 63 families, 149 genera, and 313 species (including 6 undocumented taxa: 2 families, 2 genera, and 2 species). Seventeen 17 orders, 49 families, 128 genera, and 286 species belonged to Basidiomycota; 7 orders, 9 families, 15 genera, and 21 species were of Ascomycota; and 4 orders, 5 families, 6 genera, and 6 species of primordial fungi. Among the Basidiomycota, Agaricomycetes were represented by 47 families, 126 genera, and 282 species. The most common fungi were Boletaceae (33 species), followed by Russulaceae (30), Agaricaceae (27), and Amanitaceae (24). Various species of most of the higher fungi occurred during periods with average temperatures of $23{\sim}24.9^{\circ}C$, maximum temperatures of $28{\sim}31.9^{\circ}C$, minimum temperatures of $22{\sim}22.9^{\circ}C$, > 82% relative humidity, and > 200 mm precipitation.

  • The purpose of this study was to perform retrospective data collection of the sites and types of fracture in raptors in order to enable wildlife veterinarians to manage cases of fracture more effectively. This study included raptors with fracture, rescued between January 2013 and August 2015 in the Daegu-Gyeongbuk region in Republic of Korea. The data were collected from the medical reports and radiographic findings acquired from designated animal hospitals for wild animals, the Dongin Animal Hospital and the Kyungpook wildlife rescue center. The distribution, sites, and types of fracture, and outcomes of rescue and fracture management of the raptors included in this study were analyzed. Among the 31 birds included in this study, Falco tinnunculus was the most common species. Of the 42 sites of fracture, the diaphysis of the humerus was the most common site of fracture, and comminuted fracture was the most common type. Of the 31 birds, 13 were treated surgically. Intramedullary pinning with bandaging was the most common method of surgical treatment. While 7 of the 13 birds died, 2 were reintroduced into the wild, and 4 were kept captive. This study presents the evaluation of the data on the species, sites, and types of fracture, and treatment procedures and outcomes in raptors with fractures, rescued in the Daegu-Gyeongbuk region. The findings of this study could serve as a basic database for the treatment of fracture in raptors.

  • There are 18,638 insect species recorded in Korea, representing 35.4% of Korean Biodiversity (52,628). In this study, we classified Korean common name into 11 categories (color, size, shape, plant, location, ecology, foreign language, personal name, native, physiology, positive/negative) and assigned every species into each categories and researched the meaning of Korean common names. We conducted further analysis on 506 cases of hate speech (disability, racial·regional·appearance discriminations). Also we analyzed 508 cases of Japanese expressions (person's name, place name, Japanese language), and proposed alternative words in case of inappropriate usages.

  • Common dermatophytosis in upper Egypt were studied at three hospitals in Minia city. Tinea corporis (ringworm of glabrous skin) was diagnosed in 127 patients (84 males and 53 females). Trichophyton was the most common genus and was represented by 6 species among which T. violaceum was the commonest fungus. Microsporum was represented by 4 species and M. canis was the prevalent species. Tinea pedis (ringworm of the foot) was noticed in 22 cases (13 males and 9 females) and also Trichophyton and Microsporum were the causal organisms. Three species of Trichophyton namely: T. violaceum, T. kuryngei and Trichophyton sp. were isolated. Tinea cruis (ringworm of the groin) was diagnosed in 21 patients (16 males and 5 females). Epidermophyton floccosum was the most prevalent fungus associated with tinea cruris whereas Trichophyton and Candida were less frequent. Tinea unguium (ringworm of the nail) was diagnosed in 9 patients, 8 were females and one was male and the age incidence ranged between 5 and 55 years. M. canis occurred in 2 cases and T. mentagrophytes in one case. Out of 86 cases of tinea versicolor, 71 were males and 15 were females. Malassezia furfur was the main causal agent. All patients of candidiasis and paronychia were females and Candida was the most prevalent causal agent.

  • Bacterial symbionts are common across insects, including ants (Hymenoptera: Formicidae). Reproduction-manipulating endosymbionts, such as Wolbachia, Spiroplasma, Rickettsia, and Cardinium, are closely associated with many aspects of host-insect life. In addition, phage WO plays an essential role in the phenotypic effects of Wolbachia. Although endosymbionts are possible biological control agents, there is a lack of knowledge of their rate of infection of ants in Korea. We tested a range of Korean ant species for the presence of Wolbachia, Spiroplasma, Rickettsia, Cardinium, and phage WO by extracting DNA from the ants and using specific primer sets to test the status of infections. In addition, the mitochondrial cytochrome c oxidase I (COI) gene of the host ants was amplified to confirm the molecular identification and phylogenetic relationship between the hosts. We found that infection with Wolbachia (29.6% of species) is relatively common when compared with that of other endosymbionts. Only one species was infected with Spiroplasma. Infection with Rickettsia and Cardinium was not detected in the examined ants. Most Wolbachia in ants were infected with phage WO. Although the phenotypic effects of endosymbionts in ants are still unknown, this first survey of endosymbionts in Korea is the first step toward the use of reproduction-manipulating endosymbionts.

  • This study aimed to understand whether the geo-ecological segregation of native plant species affects the root-associated fungal community. Rhizoplane (RP) and rhizosphere (RS) fungal microbiota of Sedum takesimense native to three geographically segregated coastal regions (volcanic ocean islands) were analyzed using culture-independent methods: 568,507 quality sequences, 1399 operational taxonomic units, five phyla, and 181 genera were obtained. Across all regions, significant differences in the phyla distribution and ratio were confirmed. The Chao's richness value was greater for RS than for RP, and this variance coincided with the number of genera. In contrast, the dominance of specific genera in the RS (Simpson value) was lower than the RP at all sites. The taxonomic identity of most fungal species (95%) closely interacting with the common host plant was different. Meanwhile, a considerable number of RP only residing fungal genera were thought to have close interdependency on their host halophyte. Among these, Metarhizium was the sole genus common to all sites. These suggest that the relationship between potential symbiotic fungi and their host halophyte species evolved with a regional dependency, in the same halophyte species, and of the same natural habitat (volcanic islands); further, the fungal community differenced in distinct geographical regions. Importantly, geographical segregation should be accounted for in national culture collections, based on taxonomical uniqueness.

  • This study was surveyed to identify changes of flora during three years after restoration in Cheonggyecheon stream. There are four sections in Cheonggyecheon. One and two sections are upper streams and three and four sections are down streams. It was surveyed 328 species in 2006. In 2007 and 2008, 446 and 444 species were found, respectively. This result shows that Cheonggyecheon is unstable initial condition in restored stream ecosystem. Naturalized species were 58 species in 2006 and it was respectively 61 and 63 species in 2007 and 2008. Hazard species of ecosystem were three common species during survey period. In appearance of flora per section, three and four sections constituted by natural sites such as point bars, wide flood plains, riffles and ponds, marshes, etc. were surveyed more species than one and two constructed by concrete materials and narrow flow channel. Recently, as time goes by, introduced species are being increased. And succession has mainly been progressed by one year or binary herbs and perennial herbs. Compared with other restored streams, Cheonggyecheon showed more flora than Yangjaecheon and Anyangcheon. It is judged owing to length of surveyed site, various planted species and area of inhabitation space. To manage restored stream ecosystem, monitoring is essential. Further, because change of vegetation after restoration in Cheonggyecheon is very important, continuous monitoring about Flora and Naturalized species and Hazard species of ecosystem is also very important.

  • The oligochaete worms in the genus Nais are common to freshwater habitats. These worms have a highly-developed prostomium and pigmented eye spots. All species have hair chaetae, bifid or single pointed needle chaetae on the dorsal side and ventral chaetae beginning in II with bifid crotchets. Most species of Nais genus live in areas where bottom is covered by sand, gravel or organic matter in aquatic plants. Currently, 26 species of Nais have been recorded worldwide. From the recent faunal studies, 3 species of Nais have been newly reported in Korea. Here, we newly report 6 species of Nais with diagnosis, illustrations and identification keys to Korean Nais species: N. behningi, N. pseudobtusa, N. simplex, N. bretscheri, N. stolci and N. elinguis.

  • Many areas of vegetation in the British uplands have reduced species diversity as a result of sheep overgrazing. It has been suggested that abandonment or re-wilding strategies might be used to reverse this. A likely first step would be the removal or reduction of grazing livestock from upland areas, with a presumption that this would lead to a recovery in species richness. However, we do not know if this would work, or the timescales involved. One of the important areas where more knowledge is needed is information on the size and composition of soil seedbanks as regeneration from zseed is a likely pathway of recovery. Here, we compared seedbanks in both grazed and ungrazed plots in five experiments at Moor House NNR in the northern Pennines; these sheep grazing exclusion experiments were started 52 and 63/64 years ago. Soil samples (n=10) were collected from both grazed and ungrazed plots in each experiment, and seed emergence counted in glasshouse trials. We detected only seeds of common species and very few dicotyledonous species. This suggests that the soil seedbank is unlikely to be a reliable source of the less common species for ecological restoration in these upland communities, suggesting an extinction debt. Therefore, seed addition and the creation of suitable safe-sites for germination may be needed in conjunction with grazing controls to allow the establishment of plants that will increase the species richness of the vegetation. However, this interventionist restoration approach remains to be tested.

  • Genetic and morphological studies using morphological and isozymic data from 20 populations of 6 Korea Hylotelephium were conducted to resolve the species relationships and the origin of polyploid species. The results of morphological studies suggest that triploid H. viviparum is closely related to H. verticillatum, and the high frequency alleles of two species were very similar each other in isozyme analyses. Unique fixation of $PGI-1^b$ in two species supports that H. verticillatum should be the diploid ancestor of H. viviparum. However, a unique $ALD-1^c$ allele is present in H. viviparum, and the lack of the common alleles of H. erythrostictum and H. spectabile in this species eliminated them from the candidates of another tetraploid ancestor of H. viviparum. Based on the high morphological and genetic similarities, our results supported that the Korea endemic H. viridescens might be originated from the H. erythrostictum or share a common ancestor with it. Besides, H. ussuriense is closely related with H. erythrostictum and H. viridescens.
