Environmental and Ecological Characteristics of Habitats of Abelia tyaihyoni Nakai

적 요: 한반도 특산식물인 매미꽃 자생 집단의 보전대책 수립을 위한 기초자료로 활용하고자 자생 집단의 분포와 식생환경 및 보전지위 평가를 수행하였다. 문헌자료 및 표본정보 수집과 현지조사를 통해 분포도를 작성한 결과 매미꽃은 지리산과 백운산 등 경상남도와 전라남도를 중심으로 주로 한반도 남부지방에 집중 분포하는 것으로 확인되었다. 또한 자생 집단은 주로 해발 227~744 m의 범위에 분포하였으며, 경사는 5~11 o 계곡의 중·하부 지역에 많이 분포하였다. 8개 자생 집단에 대한 식생조사 결과 29개 조사구에서 총 238분류 군이 출현하였으며, 각 조사구 내 초본층의 피도와 빈도를 기초로 매미꽃의 중요치를 산출한 결과 평균 25.34%로 나타났다. 8개 집단 내에 출현 종의 다양도는 평균 1.52였으며, 균등도와 우점도의 평균은 각각 0.83과 0.17로 산출되었다. 수집된 생물학적 자료를 바탕으로 IUCN 적색목록 기준에 의한 보전 지위를 평가 한 결과 매미꽃은 Near Threatened(준위협종)에 포함되는 것으로 나타났으며, 이에 따라 매미꽃 자생 집단의 지속가능한 보존을 위한 전략수립과 필수적인 기초연구의 내용 및 방법이 논의 되었다.ABSTRACT: The distribution, vegetation characteristics and an assessment of the conservation status of the Korea endemic species Coreanomecon hylomeconoides Nakai were investigated to collect biological basic data to formulate a conservation strategy. According to the distribution map of C. hylomeconoides based on the literature, specimen information, and local field surveys, natural populations of C. hylomeconoides are intensively distributed in the Southern regions of the peninsula, around Gyeongsangnam-do and Jeollanan-do. C. hylomeconoides was distributed in the middle and low slope adjacent to a valley. The altitude ranged from 227 m to 744 m, with inclinations of 5-10 o . As a result of a vegetation survey within natural populations, a total of 238 taxa were identified from 29 quadrates in 8 natural populations. The importance value of C. hylomeconoides is 25.34% based on the coverage and frequency of the herbaceous layer with in the populations. The species diversity of the occurrence of the species in 8 natural populations was 1.52, while the averages of species evenness and the dominance values were calculated to be 0.83 and 0.17, respectively. As a result of assessing the conservation status through IUCN Red List criteria, C. hylomeconoides was evaluated as Near Threatened (NT). Conservation strategies are also discussed for the sustainable conservation of C. hylomeconoides.

“…This species is very similar to Zabelia mosanensis (T.H. Chung ex Nakai) Hisauti and Hara, but it is distinguished in that its leaf length is half or less, and hair on the filament is absent [ 4 ]. In the current classification system, however, it is common to treat the two taxa as one taxon and treat Z. mosanensis as a synonym for Z. tyaihyonii according to the principle of priority [ 5 ].…”

“…It is important to establish a conservation strategy based on ecological conditions and the genetic diversity suitable for each species to prevent extinction and maintain continuous natural populations [ 13 , 14 , 15 ]. Previous studies on Z. tyaihyonii were mainly focused on systematics [ 16 , 17 , 18 , 19 , 20 , 21 ], and only four studies have been performed on its conservation biology [ 4 , 10 , 22 , 23 ]. The ecological characteristics of Z. tyaihyonii habitats were very thoroughly described in three studies conducted on all native habitats [ 4 , 10 , 23 ].…”

Zabelia tyaihyonii (Nakai) Hisauti and H. Hara is a perennial shrub endemic to Republic of Korea that grows naturally in only a very limited region of the dolomite areas of Gangwon-do and Chungcheongbuk-do Provinces in the Republic of Korea. Given its geographical characteristics, it is more vulnerable than more widely distributed species. Despite the need for comprehensive information to support conservation, population genetic information for this species is very scarce. In this study, we analyzed the genetic diversity and population structure of 94 individuals from six populations of Z. tyaihyonii using a genotyping-by-sequencing (GBS) approach to provide important information for proper conservation and management. Our results, based on 3088 single nucleotide polymorphisms (SNPs), showed a mean expected heterozygosity (He) of 0.233, no sign of within-population inbreeding (GIS that was close to or even below zero in all populations), and a high level of genetic differentiation (FST = 0.170). Analysis of molecular variance (AMOVA) indicated that the principal molecular variance existed within populations (84.5%) rather than among populations (17.0%). We suggested that six management units were proposed for conservation considering Bayesian structure analysis and phylogenetic analysis, and given the various current situations faced by Z. tyaihyonii, it is believed that not only the in situ conservation but also the ex situ conservation should be considered.

“…In Korea, four taxa, Z. insularis, Z. biflora, Z. tyaihyoni, and Z. densipila, are currently recognized (Hisauchi and Hara 1954;Kim 2007;Hong et al 2012). Z. tyaihyoni, named after the first Korean plant taxonomist, Professor Tyaihyon Chung (Ha Eun Herbarium, Sungkyunkwan University), is endemic to limestone area with very small population size in the central region (36 59 0 37 12 0 N) of the Korean peninsula (Kim et al 2010;Chung et al 2017). An extensive limestone mining has been resulted in significant habitat fragmentation and destruction, greatly threating population size and genetic resources.…”

The first complete chloroplast genome sequence of Korean limestone endemic, Zabelia tyaihyoni, was reported in this study. The plastome size was 156,449 bp in total length, with one large single copy (LSC; 89,242 bp), one small single copy (SSC; 17,331 bp), and two inverted repeat (IR) regions (IR a and IR b , each with 24,938 bp). The overall GC content was 38.3% and the genome contained 128 genes, including 83 protein-coding with 3 pseudogenes (two ycf2 and accD), 37 transfer RNA and 8 ribosomal RNA genes. Phylogenetic analysis of 21 representative plastomes within the Caprifoliaceae suggests that Zabelia formed a monophyletic clade with 100% bootstrap value and Z. tyaihyoni was closely related to Z. biflora and Z. corymbosa.
