“…Zone IV unifies the historical floristic zones of the southern coast, Jejudo Island, and Ulleungdo Island, which have previously been more finely divided (Appendix ), and has a high relative abundance of Orchidaceae, Asteraceae, and Rosaceae as well as specific taxa that only appear in this zone. Although Zone IV includes some inland areas, it mostly consists of regions along the coast of the Korean Peninsula and islands that are important for biodiversity, such as the oceanic island Ulleungdo (Chang & Gil, 2014; Choi, Yang, Yang, & Friesen, 2019; Holman et al., 2017) and the volcanic island Jejudo, which contains Hallasan Mountain (1,950 m). This zone ranges from the temperate zone of evergreen broad‐leaf trees (e.g., Castanopsis sieboldii ) to the cool zone of polar trees (e.g., Diapensia lapponica var.…”

The use of biota to analyze the distribution pattern of biogeographic regions is essential to gain a better understanding of the ecological processes that cause biotic differentiation and biodiversity at multiple spatiotemporal scales. Recently, the collection of high‐resolution biological distribution data (e.g., specimens) and advances in analytical theory have led to the quantitative analysis and more refined spatial delineation of biogeographic regions. This study was conducted to redefine floristic zones in the southern part of the Korean Peninsula and to better understand the eco‐evolutionary significance of the spatial distribution patterns. Based on 309,333 distribution data of 2,954 vascular plant species in the Korean Peninsula, we derived floristic zones using self‐organizing maps. We compared the characteristics of the derived regions with those of historical floristic zones and ecologically important environmental factors (climate, geology, and geography). In the clustering analysis of the floristic assemblages, four distinct regions were identified, namely, the cold floristic zone (Zone I) in high‐altitude regions at the center of the Korean Peninsula, cool floristic zone (Zone II) in high‐altitude regions in the south of the Korean Peninsula, warm floristic zone (Zone III) in low‐altitude regions in the central and southern parts of the Korean Peninsula, and maritime warm floristic zone (Zone IV) including the volcanic islands Jejudo and Ulleungdo. Totally, 1,099 taxa were common to the four floristic zones. Zone IV showed the highest abundance of specific plants (those found in only one zone), with 404 taxa. Our study improves floristic zone definitions using high‐resolution regional biological distribution data. It will help better understand and re‐establish regional species diversity. In addition, our study provides key data for hotspot analysis required for the conservation of plant diversity.

The use of biota to analyze the spatial range and distribution of biogeographic regions is essential to gain a better understanding of the ecological processes that cause biotic differentiation and biodiversity at multiple spatiotemporal scales. Recently, the collection of high-resolution biological distribution data (e.g., specimens) and advances in analytical theory have led to their quantitative analysis and more refined spatial delineation. This study was conducted to redefine floristic zones in the southern part of the Korean Peninsula and to better understand the eco-evolutionary significance of the spatial distribution patterns. Based on the distribution data of 309,333 vascular plant species in the Korean Peninsula, we derived floristic zones using selforganizing maps. We compared the characteristics of the derived regions with those of historical floristic zones and ecologically important environmental factors (climate, geology, and geography). In a clustering analysis of the floristic assemblages, four distinct regions were identified, namely, the cold floristic zone (Zone I) in high-altitude regions at the center of the Korean Peninsula, cool floristic zone (Zone II) in high-altitude regions in the south of the Korean Peninsula, warm floristic zone (Zone III) in low-altitude regions in the central and southern parts of the Korean Peninsula, and maritime warm floristic zone (Zone IV) including the volcanic islands of Jejudo and Ulleungdo. A total of 1,099 taxa were common to the four floristic zones. Zone IV had the highest abundance of specific plants (those found in only one zone), with 404 taxa. This study improves floristic zone definitions using high-resolution regional biological distribution data. It will help better understand and re-establish regional species diversity. In addition, our study provides key data for hotspot analysis techniques required for the conservation of plant diversity.

The complete chloroplast genome of Sorbus hupehensis var. paucijuga was sequenced with Illumina HiSeq 2000 platform. It was a typical quadruple structure as other plants of Sorbus with 160,050 bp in length, including a large single-copy (LSC: 87,905 bp) region and a small single-copy (SSC: 19,325 bp) which were separated by a pair of inverted repeats (IRa, b: 26,410 bp) region. The overall GC content is 36.5%. A total of 130 genes was annotated which contained 85 protein-coding genes including the Trans splicing gene of rps12, 37 tRNA genes, and 8 rRNA genes. ML phylogenetic analysis compared with 7 expressed chloroplast genomes of Rosaceae revealed that S. hupehensis var. paucijuga was a sister to other Sorbus species. Six species of Sorbus were divided into two groups, the species of group one is distributed in Asia and the species of group two distributed in Europe. Among group one, S. hupehensis var. paucijuga had the closest genetic relationship with S. ulleungensis which is a New Endemic Species on Ulleung Island of Korea, and followed by S. setschwanensis which is only distributed in Sichuan and Guizhou of China. Sorbus hupehensis var. paucijuga has a relatively close relationship with the other three species of Sorbus in the group two. And, it has a relatively distant from other genera of Prunus mongolica and Rosa rugosa.
