Seasonal variation in marine macroalgal community structure was examined at the intertidal zones of Heuksando and Hongdo, Shinan, Korea, from July 2008 to May 2009. In total, 86 macroalgal species were identified, including 12 green, 19 brown, and 55 red algae; 67 species at Heuksando and 70 species at Hongdo, were observed. Annual seaweed biomass was 252.44 g dry $wt/m^2$ at Heuksando and 217.67 g dry $wt/m^2$ at Hongdo. The dominant seaweed in importance value (IV > 15) differed between the sites: Sargassum thunbergii at Heuksando and Corallina pilulifera at Hongdo. The vertical distribution pattern of seaweeds from the upper to lower intertidal zones at Heuksando was Gloiopeltis spp., Ulva spp. - S. thunbergii, S. fusiforme, Hildenbrandia rubra - S. thunbergii, C. pilulifera. On the rocky shore of Hongdo, seaweed zonation was distinct: Porphyra yezoensis, Gloiopeltis spp., Ulva spp. - C. pilulifera, S. fusiforme, Myelophycus simplex - Chondrus ocellatus, C. pilulifera, and Carpopeltis affinis. Annual seaweed coverage, richness index (R), evenness index (J'), and diversity index (H') values were greater at Hongdo (41.35%, 12.82, 0.59, and 2.50 respectively) than at Heuksando (31.54%, 11.93, 0.44, and 1.87 respectively), which may indicate that the seaweed community at Hongdo is more stable relative to the one at Heuksando.

During the breeding seasons in 2002 and 2003, the influences of vegetation cover on breeding processes of Black-tailed Gulls (Laurs crassirostris) were studied on Hongdo Island. We checked dutch sizes, calculated hatching success and survival rates on day 15 and a vegetation cover, There was significant positive relationship between vegetation cover and hatching success, and survival on day 15. In order to analyze the relationship, sample nests were categorized as 'exposed' and 'covered' nests, and the breeding processes at each nest were compared. Hatching success and survival on day 15 in covered nests were significantly higher than ones in exposed nests. However, in clutch size, there was no significant difference. The rate of the hatching and survival failure was different amongst the categorized nests. The primary cause of hatching failure in covered and exposed nests was 'disappeared', and the primary causes of survival failure on day 15 were 'disappeared' and 'killed by adults'. The failure in exposed nests was significantly larger than that of covered nests. In the breeding of Black-tailed Gulls on Hongdo Island, vegetation cover influenced the survival of eggs and chicks as the cover provided shelter against predators and extreme weather.

The purpose of this study was to identify the natural habitat of Bulbophyllum inconspicuum Maxim. in Hongdo, Jeonnam Province, South Korea. A field investi gation was conducted between May 2019 and May 2021. The growth of B. inconspicuum species was confirmed in three known regions based on National Survey on the Distribution of Endangered Species. Additionally, in the area investigated, 37 new regions harboring B. inconspicuum were detected. The newly observed B. inconspicuum grew naturally on Quercus mongolica, Rhaphiolepis indica var. umbellata, Carpinus turczaninowii, and rocks. Most of them were found on southeast and southwest slopes with altitude above 250 m. As few as 10 up to hundreds of B. inconspicuum were found in clusters. Close to their habitat, Calanthe sieboldii Decne. ex Regel, C. aristulifera Rchb. f. and C. × kibanakirishima Maek. were also found. As Hongdo is an island, multiple endangered species were found together. Thus, once the habitat of a certain plant is discovered, it is very likely that illegal collection of several other species will also occur. Proactive internal and external measures are needed to preserve these species.

고들빼기속에 속하는 홍도산 홍도고들빼기의 학명은 이고들빼기와 절영풀의 잡종인 Crepidiastrum ×nakaii로 기록되어 왔다. 홍도 식물상을 조사하는 과정에서 홍도고들빼기의 분류학적 실체를 재검토하였다. 이를 위해 홍도고들빼기의 형태적 특징과 지리적 분포 및 internal transcribed spacer (ITS) 염기서열을 고들빼기속 근연종들과 비교하였다. 형태적 특성 조사에서, 홍도고들빼기는 짧고 굵은 아관목성 줄기와 8개의 내총포편 및 10 내지 12개의 소화수를 갖는 점에서 갯고들빼기와 유사한 반면, 개화기에 시드는 뿌리잎과 막질로 예 거치인 줄기잎 및 부리가 있는 수과 형태 등에서는 이고들빼기와 유사하였다. 한편 이고들빼기와 갯고들빼기는 홍도와 인근 섬 지역에 자라지만, 절영풀은 분포하지 않는다. 이러한 형태 및 분포 조사결과, 홍도고들빼기의 학명은 이고들빼기와 절영풀의 잡종인 C. ×nakaii가 아니라, 이고들빼기와 갯고들빼기의 잡종인 C. ×muratagenii로 판단된다. 하지만, ITS 염기서열은 조사된 종들을 구별할 수 있는 해상력을 보여주지 못하였다.

이 연구는 지역의 소리환경의 정체성을 회복하고 소리문화로 계승/발전시키기 위하여, 그 지역의 소리경관 자원을 발굴하여 보존하고 육성하기 위한 방안을 마련하기 위한 조사연구이다. 이러한 목표를 위해, 이 연구는 한국의 서남해안의 섬인 홍도를 대상으로 주민의 면담조사와 소리들으며 걷기를 이용한 관찰조사를 수행하였다. 조사결과, 홍도에서 들을 수 있는 소리는 새소리, 파도소리, 바람소리, 갈매기소리, 몽돌구르는 소리 등의 자연의 소리, 그리고 뱃고동소리, 선박의 안내방송, 관광객들의 말소리, 교회의 종소리, 등대의 에어사이렌 등의 인공의 소리에 이르는 많은 소리가 있는 것으로 확인되었다. 또한 연구의 결과, 홍도의 고유한 사운드스케이프를 회복하기 위해서는 몇가지 방안을 배려할 필요가 있는 것으로 조사되었다. 즉, 선박 안내방송의 효율적 운영개선, 몽돌해수욕장의 선착장 이전, 당산제 행사의 운영 및 관리, 홍도 등대 및 무종의 보존 및 관리, 마을 복개하천의 복원 및 정비, 마을 공동어시장의 운영 및 관리, 풍어제 및 홍어축제의 복원, 홍도운동회의 운영관리, 뱃고동소리의 음질 변경, 상여소리 등의 민속문화자원의 복원, 생태자연환경 및 도서해양환경의 보존활동, 지역의 활력과 매력을 위한 어메니티 증대를 꾀하는 방안이 필요한 것으로 파악되었다. 또한 많은 관광객들이 이러한 홍도의 사운드스케이프의 정체성과 소리환경의 중요성을 깨닫고 홍도의 사운드스케이프를 직접 체험하고 느낄 수 있도록 하기 위한 소리지도 (Sound Map)를 작성하였다.

We studied variation in clutch size, hatching, fledging and breeding success of the Black-tailed Gull (larus crassirostris) at Hongdo Island, which supported the largest breeding colony of the species, in South Korea in 1997 and 2000 to 2003. Cluck size was recorded in 1,388 nests and breeding success was estimated in 83 nests. Mean clutch size was 1.89 t 0.65. A total of 63.9% of the eggs hatched and 53.5% of the chicks survived until fledged. Breeding success was 34.2%. Causes of breeding failure were eggs missing (14.9%), rotten eggs (15.5%) and predation (2.4%) during the incubation period and chicks missing(35.8%), starvation (7.4%) and pecked chicks (3.2%) during the chick rearing period. In 2002, the main causes of breeding failure were eggs missing (17.2%) and rotten eggs (6.9%) during the incubation period and missing chicks (15.5%), starvation (3.5%) and pecked chicks (6.9%) during the chick rearing period. Most chick mortality occurred within three days after hatching.

Until now, five species (Meghimatium bilineatum, M. fruhstorferi, Limax flavus, L. marginatus, Deroceras reticulatum) in three genera of families Philomycidae and Limacidae have been reported in Korea. Philomycidae is a family of air-breathing land snails. Meghimatium hongdoensis sp. nov. is described based on its middle size (60-80 mm in body length), its body coloration (dark-red yellow), no dorsal with streaks, its genitalia, and 16rDNA sequence analysis. Specimens of this new species were collected from Hongdo island, Sinan-gun, Jeollanam-do, Korea. This species is only known from the type locality at Hongdo to date. It could be found in high-humidity sites. Meghimatium uniforme (Laidlaw 1937) was the first one reported in Korea. It was also collected from Gageodo island, Sinan-gun, Jeollanam-do, Korea. In this study, morphological characteristics including their radula and genital structures of these two species were described. Preliminary results of mitochondrial 16S rDNA sequencing and phylogenetic analyses indicated that these species belonged to the Korean clade.

Sea gulls are high trophic level consumers in the coastal environment, and thus, which have been widely used to monitor contamination biomagnified through a food web. However, such monitoring studies using sea gulls have been rare in the Korean literature. The National Environmental Specimen Bank chose eggs of a black-tailed gulls (Larus crassirostris) to serve as an environmental specimen for the long-term monitoring of the coastal ecosystem affected by terrestrial pollutants. Black-tailed gull eggs were collected from Baengnyeongdo, Hongdo and Uleungdo, and their DDTs and total mercury content were determined. The highest concentration of ${\Sigma}DDTs$ was $231.6{\pm}106.1{\mu}g/kg$ wet in Baengnyeongdo, followed by $230.0{\pm}123.8{\mu}g/kg$ wet in Ulleungdo, and $117.7{\pm}18.3{\mu}g/kg$ wet in Hongdo. In addition, total mercury was detected at $414.5{\pm}97.6{\mu}g/kg$ wet in Ulleungdo, $363.9{\pm}123.6{\mu}g/kg$ wet in Hongdo, and $237.5{\pm}42.3{\mu}g/kg$ wet in Baengnyeongdo. Relatively high concentrations of the target pollutants were recorded in specimens from Ulleungdo. Additional comprehensive and prolonged studies are required to elucidate spatial and temporal patterns of contamination in black-tailed gull eggs with regard to monitoring contaminant trends in eggs and prey.
