-To elucidate genetic diversity of common reed in Korea, we collected a total of 674 common reed plants from 27 regions in South Korea. Hierarchical clustering using 7 morphological traits divided the 27 common reed populations into 7 groups. Random amplified polymorphic DNA (RAPD) results identified three distinct groups of common reed. Common reed accessions in group I mostly inhabit coastal areas. Group II includes reeds mostly collected from inland areas. Group III consists of common reed accessions collected from inland and coastal areas, suggesting that this group might contain hybrids. In summary, we suggest that parapatric speciation might be an important factor in the genetic diversity of common reed and geographical speciation of common reed that might be also affected by environmental gradients.

“…Most of the natural forests in Korea are located in mountains; thus, owing to the lack of accessibility, mountain forests are less affected by anthropogenic activities and have continued to grow after regeneration. Mountain forests are an important ecosystem component that plays a key role as a refuge for vulnerable species (Chung et al, 2016(Chung et al, , 2018 and an ecological corridor connecting various ecosystems (Choi, 2004;Cho et al, 2008;Hayes, 2010;Chung et al, 2016Chung et al, , 2018. The network of mountain ridgelines has been traditionally conceptualized in Korea and are called "Daegan" and "Jeongmack" (Choi, 2004).…”

Deforestation is a global issue; however, each deforestation phenomenon occurs within its own local context. Elucidating this context in detail is important to prevent deforestation and maintain sustainable ecosystem management. In this study, we analyzed the land cover changes, forest characteristics, and modeled the forest decline over the last two decades to reveal the pattern and affecting factors of deforestation in the Honam-Jeongmaek mountain range. Forests less than 50-years-old dominate the study area, indicating they were mainly regenerated after the 1970s. Reforestation policies such as planting trees have helped forest regeneration. In the study region, as deforestation occurred, agricultural and residential areas decreased, and barren and grassland increased. We applied the Weibull regression model to determine forest survivorship and covariates. The deforestation risks are significantly different among regions; protected areas lose less forest than non-protected areas but the losses in protected areas were also significant, with approximately 5% from 2000 to 2020. Areas of higher elevation and steep slopes experience less deforestation, whereas areas closer to the mountain ridge are at greater risk. With survival analysis, it is possible to assess the risk of deforestation quantitatively and predict long-term survival of forests. The findings and methods of this study could contribute to better forest management and policymaking.

“…Although these conservation strategies help to sustain the biodiversity of maeulsoops, they do not consider how landscape characteristics influence their biodiversity. This perspective is urgently needed because maeulsoops expand or connect mountain forests that play an important role in maintaining biodi-versity in Korea (Price 2003;Cho et al 2008;Kwon et al 2008;Kang et al 2012).…”

Questions At what spatial scales do plant species with different dispersal potentials respond to landscape characteristics? Do seed rain data support these scale‐dependent responses? Does the relative importance of local factors and surrounding landscape characteristics vary according to species dispersal potential? Location Agricultural landscape, Jinan County, Korea. Methods Forest plant species from 15 traditional Korean village forests, maeulsoops, were recorded and categorized into short‐distance dispersal (SDD) and long‐distance dispersal (LDD) species based on dispersal mode. Seed rain samples were collected every 2 wk for 4 mo and identified at the genus level. Local factors (anthropogenic influence and maeulsoop area) were assessed through field surveys and satellite imagery. Landscape characteristics surrounding maeulsoops (forest cover diversity, composition and fragmentation) were assessed at multiple spatial scales using Shannon‐Wiener index and PCA. The best regression model at each scale was identified by model selection based on AICc, and the effect of each explanatory variable on species richness was quantified with hierarchical partitioning. Results A total of 107 forest plant species (39 SDD and 68 LDD) were recorded, and a total of 25 bird‐dispersed genera were identified in seed rain samples. Species richness in plant records and genus richness in seed samples were strongly affected by anthropogenic influence and maeulsoop area, respectively. SDD species richness was significantly and positively influenced by total forest cover at small scales of around 150 m. In contrast, LDD species richness was significantly influenced by deciduous forest cover at large scales (1500–3500 m). At these larger scales, the relative importance of landscape characteristics for species richness was higher for LDD than for SDD. These results for LDD species were most notably supported by genus richness in seed rain data. Conclusions The most important findings of the study highlight that (1) plant species responses to forest cover are scale‐dependent; and (2) dispersal potential mediates the effects of local and landscape factors on plant species richness. The results suggest that conservation strategies for native forest species in maeulsoops should not only focus on habitat‐specific characteristics but also consider species‐specific interactions with surrounding landscapes.
