In this study, we studied the elevational patterns of plant diversity and examined the effectsof climatic factors, area, geometric constraints or mid-domain effect and net primary productivityon the observed diversity patterns along the ridge of the Baekdudaegan Mountains, South Korea. Plant data were colleted from 1,100 plots along a elevational gradient on the ridge of theBaekdudaegan Mountains. A total of 802 plant species from 97 families and 342 genera wererecorded. The elevational patterns of α plant diversity such as species richness andShannon-Wiener index along the ridge of the Baekdudaegan Mountains depicted distinctlyunimodal patterns, whereas the β diversity increased with elevation. The mid-domain effect wasthe most powerful explanatory variables for α diversity. However, climatic factors were betterpredictors for β diversity. This study suggests that different elevational patterns may beobserved between different diversity measurements even in the same taxon and that a combined interaction of some factors influences species diversity patterns along the elevational gradient onthe ridge of the Baekdudaegan Mountains, South Korea. 본 연구는 남한지역 백두대간 마루금 일대의 고도별 식물 다양성 분포 패턴 및 기후인자, 면적, 기하학적 억제인자, 순일차 생산량이 고도별 식물 다양성 분포 패턴에 미치는 효과를 구명하기 위해 수행되었다. 백두대간 마루금 일대를 따라 위치한 1,100개의 조사구에 대한 식생조사 결과, 총 97과 342속 802종의 식물종이 관찰되었으며, 고도에 따른 식물종의 α 다양성을 나타내는 종풍부도와 Shannon-Wiener지수는 단봉형 패턴을 나타내는 반면, β 다양성을 나타내는 Jaccard와 Chao-Jaccard 유사도 지수는고도에 따라 일반적으로 증가하는 경향을 나타내었다. 또한, 이러한 분포 패턴을 제어하는 인자로서 기하학적 억제인자가 α 다양성을 설명하는 가장 중요한 인자로 나타났으며, β 다양성은 기후인자가 가장높은 설명력을 가지는 인자로 나타났다. 본 연구는 동일한 분류군 내에서도 다양성 측정방법에 따라 상이한 고도별 분포 패턴 및 제어인자를 가진다는 것을 제시하며, 백두대간 마루금 일대의 식물 다양성을제어하는 인자가 단순히 하나가 아닌 몇 가지 인자의 복합작용에 의해 나타나는 현상임을 의미한다.

권순직,김태근,전영철 국립공원공단 국립공원연구원 2024 국립공원연구지 Vol.15 No.1

: 변산반도국립공원 일대 수계에 서식하는 저서성 대형무척추동물의 생물다양성을 파악하기 위하여 2023년 3월부터 9월까지 현장조사를 실시하였다. 전체 17개 조사지점에서 관찰된 저서성 대형무척추동물은 총 4문 6강 18목 59과 94종이 출현하였고, 조사지점 평균 출현종수는 26.1(±5.3)종이었다. BS11에서 35종으로 가장 많은 종이 조사되었고, BS09에서 16종으로 가장 적은 종이 조사되었다. 전반적으로하천 차수가 낮은 하천은 출현 종수가 적은 편이었고, 하천 차수가 높을수록 출현 종수가 다소 증가하였다. 군집분석 결과 다양도지수는 1차나4차 하천보다는 2∼3차 하천에서 지수값이 높게 나타났다. 변산반도국립공원의 전체 조사지점에 대한 군집 변이 값(베타다양성)과 베타다양성에 대한 각 조사지점의 기여 값(Local Contribution to Beta Diversity, LCBD)을 산출한 결과 베타다양성 값은 0.509이었고, 조사지점중에 BS03에서 LCBD 값이 0.135으로 가장 높게 나타났다. LCBD 값을 이용하여 멸종위기 야생생물 II급에 해당하는 대모잠자리(Libellula angelina)나 국외반출 승인대상 생물자원인 애반딧불이(Luciola (Luciola) lateralis)와 같은 특이종의 서식지를 탐색하거나, 서식지 교란이발생하여 생물상에 변동이 발생한 지역을 구분하는데 유용한 정보를 제공할 수 있다. 이러한 정보를 이용하여 서식지를 보전하거나 보호지역내에서의 서식지 관리를 위한 유용한 정보를 제공할 수 있을 것으로 기대된다. This study aimed to investigate the diversity of benthic macroinvertebrates in the Byeonsanbando National Park. A total of 94 species belonging to 59 families, 18 orders, and six classes in four phyla were identified during the survey period (March– September, 2023). The taxa richness at the 17 sampling sites ranged from 16 to 35 with an average of 26.1 (±5.3). The taxa richness of the low stream-order sites was relatively lower than that of the higher stream-order sites. The overall benthic macroinvertebrate communities were characterized by moderate competitiveness and low stability based on the Shannon diversity index. This indicates that several sites adjacent to villages and farmlands were influenced by artificial disturbances, such as stream maintenance projects and monotonous microhabitat conditions. The β-diversity value was 0.509 with the highest local contribution to Beta diversity (LCBD) value at BS03 (0.135). LCBD can be a useful parameter for species conservation such as Libellula angelina (Class II endangered wildlife) and Luciola (Luciola) lateralis (biological resources subject to the approval of outbound transfer) inhabiting Byeonsanbando National Park. Additionally, the LCBD is suitable for constructing strategies for habitat preservation, particularly in regions of national parks with high conservation values.

이명현,김재곤,김경휘,김민선,윤성식 한국식품과학회 2023 Food Science and Biotechnology Vol.32 No.4

Imbalanced intestinal microbiota is associated with diseases, including inflammatory bowel disease and obesity, and diet can alter the structure of the gut microbiota. In this study, the effects of dietary treatments including the potential probiotic Lactiplantibacillus plantarum FBT215 with/without prebiotics on the intestinal microbiota composition of mice were investigated. Lactiplantibacillus plantarum FBT215 administration significantly decreased the Firmicutes/Bacteroidetes ratio and increased the abundance of Muribaculum and Duncaniella. The diversity within and between groups was measured according to α and β diversity metrics, respectively. The Shannon index of α diversity decreased significantly in all treatment groups except the probiotic group, although this group showed an increase in the Chao1 index. Principal coordinate analysis of β diversity showed that the groups had different species distributions. Finally, gamma-aminobutyric acid (GABA) concentration increased in groups fed L. plantarum FBT215. These findings improve our understanding of the association between the gut microbiota structure and specific probiotic/prebiotic-containing diets.

Understanding how future climate conditions will be impact on the biodiversity and species composition is important, because biodiversity becomes more important in environment assessment. To understand the biological changes including diversity and species composition over time (temporal variation within a year), the species diversity and composition of ground beetles were investigated in two well-preserved areas in the Sobaeksan National Park using pitfall traps. In addition, relationships between ground beetles and environmental variables were studied by considering temporal variation. We collected 2,146 ground beetle specimens representing 45 species, and individual-based rarefaction curves indicated that similar species richness was found between Geumseon Valley (GV) and Namcheon Valley (NV). The Bray-Curtis matrix comparisons between study sites were characterized by similar ground beetles sample heterogeneity, while temporal variations in abundance, species richness, and -diversity of ground beetles showed rather difference over time according to location of study sites. In GV site, minimum temperature was selected as the best predictor for abundance, species richness, and -diversity of ground beetles, while those relationships in NV site were more complicated. In conclusion, our study suggests that understanding the different response of ground beetles to climatic variables related to local habitat conditions is important to predict the effect of climate change on biological communities.

The Bray-Curtis matrix comparisons between study sites were characterized by similar ground beetles sample heterogeneity, while temporal variations in abundance, species richness, and b-diversity of ground beetles showed rather difference over time according to location of study sites. In GV site, minimum temperature was selected as the best predictor for abundance, species richness, and b-diversity of ground beetles, while those relationships in NV site were more complicated. In conclusion, our study suggests that understanding the different response of ground beetles to climatic variables related to local habitat conditions is important to predict the effect of climate change on biological communities.

김경민,류태훈,서상재 한국육종학회 2010 한국육종학회지 Vol.42 No.2

본 연구는 대규모 GMO 격리포장에서 비타민 A 영양성분이 강화된 황금벼의 안정성 평가에 대한 가이드라인 및 프로토콜을 개발하고자 모본으로 사용된 ‘낙동’을 대조로하여 수행하였다. 경북대학교 농업생명과학대학 GMO 실습격리포장에서 총 사용면적 4,700 m2에서 황금벼와 모품종인 ‘낙동’에 대해 거미류를 포함한 곤충류 다양성을 조사하였다. 조사기간동안 채집된 개체들은 기능별로 해충군, 천적군, 거미군으로 크게 구분하여 계수하였으며, 조사된 개체군의 해충 This study was carried out to develop of macro-protocol and the biosafety guide for ‘Nakdong’, and ‘Golden Rice’ (genetically modified vitamin A rice) by large scale field trial of GM crops. Typically, when a new GM crop is created, breeders should conduct field test to make sure the GM crop is safe, and provide some information on GM crops for approval. A total of isolated 4,700 m2 field for trial of GM crops were prepared, and ‘Nakdong’ and ‘Golden rice’ were cultivated by standard method of RDA (Rural Development Administration, Korea). Field studies indicated that the population densities of insect pests and natural enemies have no difference between two varieties. While insect pest density on ‘Nakdong’ was slightly higher than on Golden Rice, but natural enemy density on Golden Rice was a little higher. These results provided the insect diversity for risk assessment analysis of Golden Rice and suggested that the macro-protocol could be useful to detect GM plants.

지역적인 규모에서 식물다양성의 보전을 위해서는 기초적인 정보가 바탕이 된다. 조사의 결과로 나타나는 식물의 종수는 조사의 면적과 조사지역 내에 분포하는 다양한 생육지의 수와 밀접하게 연관된다. 경상북도 울진군의 마룡산과 대소산 일원에서 각각 9회와 6회에 걸쳐 식물자원을 조사하였다. 조사경로에 다양한 생육지가 포함되도록 계획하였다. 조사의 결과로 마룡산 일원에서는 112과 349속 548종 10아종 34변종 2품종 594분류군이 대소산 일원에서는 89과 270속 400종 9아종 25변종 434분류군이 조사되었다. 21개의 생육지로 구분하여 관찰된 식물을 정리하면 계곡주변의 전이대에 분포하는 식물과 건조한 초원에 분포하는 식물이 높은 비율을 차지하였다. 해안에 위치한 전통적인 묘지는 식물의 주요한 분포지로 기능하였다. 2개 지역에서 한국고유종은 19분류군이 조사되었다. 2개 지역에서 식물구계학적 특정식물종은 Ⅴ등급이 1분류군, Ⅳ등급이 11분류군, Ⅲ등급이 24분류군이 조사되었다. 귀화식물은 총 77분류군이 조사되었고 그중 생태계교란외래식물은 4 분류군이 분포하였다. 마룡산 일원과 대소산 일원에 분포하는 식물에서 나타나는 차이는 먼저 조사지역 내에 분포하는 각각의 생육지 크기 차이에 따른 것으로 판단되었다. 또한 대소산 일원이 주변의 산지와 연결되어 있지 않고 주거지와 경작지에 둘러싸인 고립된 공간에 해당하였기 때문으로 판단되었다. Basic information such as flora and their distribution are the key factors to consider for preserving plant diversity on a regional level. The number of plant species identified through a survey is closely related to the survey area and the number of habitats distributed within the survey area. In this study, we surveyed the flora of Mt. Maryong-san (PH) and Mt. Daeso-san (YH) located in Uljin-gun, Gyeongsangbuk-do, six and nine times, respectively. We planned to include a variety of habitats in the survey routes. As a result, we identified a total of 594 taxa composing of 112 families, 349 genera, 548 species, 10 subspecies, 34 varieties, and 2 formulas in the Mt. Maryong-san (PH) area and a total of 434 taxa composing of 89 families, 270 genera, 400 species, 9 subspecies, and 25 varieties in the Mt. Daeso-san (YH) area. Of the plants observed in the 21 habitats, the plants distributed in the transition zone around the valley and the dry grassland accounted for the highest proportion. The traditional graveyards located on the coast also served as the major habitat for the distribution of some plant species. In the two graveyards, 19 taxa of endemic plant species were surveyed. Moreover, the identified floristic target species included 1 taxon for grade Ⅴ, 11 taxa for grade Ⅳ, and 24 taxa for grade Ⅲ. A total of 77 taxa of naturalized plants were identified, and four of them were invasive alien plants as designated by the Ministry of Environment. The differences in the plants distributed in the area of Mt. Maryong-san (PH) and Mt. Daeso-san (YH) were mainly due to the difference in the size of each habitat distributed within the survey area. Moreover, it was judged that the entire vicinity of Mt. Daeso-san (YH) was not connected to the surrounding mountains and was an isolated area surrounded by farmland and residential areas.
