  • This basic study is to present the methods and raw data for carrying out to objectively assess an ecosystem by developing the plant ecological indices. The results are as follows. The plant ecological indices were 7 units including RI (Rare Index), EI (Endemic Index), SI (Specific Index), NI (Naturalized Index), UI (Urbanized Index), Pte-Q (Pteridophyta Index) and HI (Halophytes Index). The vascular plants in Mt. Waryong, Mt. Bongmyeong and Bito island were summarized as 471 taxa including 104 families, 294 genera, 419 species, 3 subspecies, 41 varieties and 8 forms. We surveyed 5 taxa of rare plants, 7 taxa of endemic plants, 38 taxa of specific plants by floristic region, 40 taxa of naturalized plants, 1 taxa of invasive alien plant, 19 taxa of pteridophyta and 14 taxa of halophytes. Bito island had the highest RI was 1.2%. Mt. Bongmyeong was 1.4% higher than other sites. If the SI of 2.9% was the highest in Bito island. Bito island was the highest NI, and the UI was the hightest in Mt. Waryong. Mt. Bongmyeong was the lowest NI and UI. In Mt. Waryong and Bito island, the highest DI was 9.1%. The Pte-Q of Mt. Waryong was 1.3 higher than the other sites. Bito island, the highest HI was 8.1%. Overall, 1.5% of RI, 1.9% of EI, 2.3% of SI, 8.5% of NI, 14.3% of UI, 9.1% of DI, 1.0 of Pte-Q and 3.0% were analyzed with HI.

  • Prangos fedtschenkoi (Regel et Schmalh.) Korovin (Apiaceae) is an endemic species for mountainous Middle Asia, which is both a rare and useful plant. Organic extractions from this species are being used in pharmaceutics and cosmetology. In recent years, P. fedtschenkoi distribution area has considerably decreased, presumably, resulting from human activities such as agriculture, construction works, overgrazing and collection from wild for pharmaceutic purposes. Six populations were found in Uzbekistan and their genetic divergence and differentiation were studied with 10 inter-simple sequence repeat (ISSR) markers, selected out of 101. Totally 166 amplified ISSR fragments (loci) were revealed, of which 164 were polymorphic. Relatively moderate level of polymorphism was found at population level with polymorphic bands ranging from 27.71% to 47.59%. Mean P = 39.05%, $N_a=1.40$, $N_e=1.25$, S.I. = 0.21, and $H_e=0.14$ were revealed for all loci across six populations. AMOVA showed higher variation among populations (62%) than within them (38%). The Bayesian model determined 5 clusters, or genetic groups. The posteriori distribution of the Theta II estimator detected full model identifying high inbreeding, intensified by low gene flow (Nm = 0.3954). Mantel test confined population 6 as distinct cluster corresponding to geographic remoteness (R = 0.5137, $p{\leq}0.005$). Results were used as the bases for developing conserve measures to restore populations.

  • Background: The southern and eastern parts of the Gobi Desert area are a unique dry ecosystem with a diverse regional desert, semi-desert, and mountain dry steppe flora. This area habitat is located at the overlap of different floristic regions; on its northeast side, Central Asian desert flora is dominating, and on the eastern side, East Asian flora is observed. The comprehensive survey was carried out to find the floral diversity of the medicinal plants on the region. Methods: All recorded species in this study were based on the collected voucher specimens between June and August in the year 2017. Results: We recorded 23 families, 57 genera, and 78 species of vascular plants. The families Asteraceae (15 species), Fabaceae (10 species), and Amaranthaceae (10 species) were represented most in the study area, while Caragana (5 species), Salsola (4 species), and Arnebia (3 species) were the most common genera found. Conclusion: Conservation status for remarkable species was also reviewed based on the literature. Around the study area, 24 species as "sub-endemic," 10 species as "very rare," 4 species as "rare," 1 species as "alien," 13 species as "relict," 10 species as "Red Book," 2 species as "endangered (EN)," 3 species as "vulnerable (VU)," 3 species as "near threatened (NT)," and 2 species as "least concern (LC)" plants are growing.
