Cardiocrinum cordatum (Thunb.) Makino (Family: Liliaceae), commonly known as ‘Ubayuri’, is native to Japan and some islands in the Russian Far East. It has high value as food, medicinal, and ornamental species. The aim of this study was to isolate and characterize the main chemical constituents of the leaves of C. cordatum. A total of 19 compounds, namely caffeic acid (1), caffeic acid methyl ester (2), caffeic acid β-glucopyranosyl ester (3), caffeic acid 4-O-β-glucopyranoside (4), ferulic acid (5), isoferulic acid (6), protocatechuic acid (7), syringic acid (8), 2,6-dimethoxy-p-hydroquinone 1-O-β-glucopyranoside (9), esculetin (10), taxifolin (11), quercetin 3-O-(6-O-α-rhamnopyranosyl)β-glucopyranoside-7-O-β-rhamnopyranoside (12), 2,7-dimethyl-2,4-diene-deca-α,ω-diacid β-glucopyranoside (13), 4-[formyl-5-(methoxymethyl)-1H-pyrrol-1-yl]butanoic acid (14), (3Z)-3-hexenyl β-glucopyranoside (15), tryptophan (16), adenine (17), adenosine (18), and 2-deoxyadenosine (19) were isolated using various chromatographic methods. The structures of isolated compounds were elucidated on the basis of their NMR spectroscopic data. All these compounds were isolated for the first time from the genus Cardiocrinum. Phenolic acid derivatives and flavonoids can be considered as chemotaxonomic markers in the leaves of Cardiocrinum species.

The first lichenological inventory in Koryakia has resulted in the list of 315 species reported from Parapolsky Dale, within and in vicinities of the Koryak State Reserve. Altogether 46 species are published from the Kamchatka Territory for the first time, including Lecanographa grumulosa new to Russia, East Asia and Beringia; Cercidospora trypetheliza, Lecania dubitans, Pertusaria borealis, Piccolia ochrophora, Protoparmelia cupreobadia, Rimularia badioatra and Strangospora moriformis new to Russian Far East; Abrothallus bertianus, Cladonia strepsilis, Physciella melanchra, Rimularia badioatra, Sclerococcum parasiticum, Sphinctrina leucopoda and Strangospora moriformis new to Beringia. The lichen diversity of the study area is relatively poor due to natural reasons. Comparison with neighboring regions (Kamchatka Peninsula, Chukotka, Magadan Region, Yakutia and Alaska) shows that the lichen flora of Parapolsky Dale contains almost no specific species. The majority of the species recorded here are also known from neighboring regions, especially Alaska and Kamchatka Peninsula.

Pale-flowered licorice (Glycyrrhiza pallidiflora Maxim.) is the pea family (Fabaceae) perennial herb. It is a Russian Far East endemic. Pale-flowered licorice refers to the false (not sweet) licorice section (Pseudoglycyrrhiza Krug.), which do not accumulate glycyrrhizin derivatives. The G. pallidiflora successful introduction has been carried out over the past 5 years in the “Apothecary garden” territory, FRC UUH SB RAS, Kemerovo. Phytochemical studies screening biologically active compounds main classes of the plant aerial part confirmed the presence of a complex of phenolic compounds. The content of catechin derivatives and condensed-type tannins - proanthocyanidins (PAC) data in G. pallidiflora herb were obtained for the first time. In different years of cultivation, licorice herb accumulates phenolic compounds - up to 2.83 ± 0.22% in terms of gallic acid, flavonoids - up to 2.44 ± 0.03% in terms of rutin and PAC in terms of cyanidine chloride - up to 2.61 ± 0.11%. It was found that the maximum content of the phenolic compounds and PAC sum was observed in the herb for 4 years development. The greatest number of flavonoids accumulates in the herb harvested in the 3rd year of cultivation. A positive significant linear relation was found between antioxidant activity (AOA) and the total phenolic compounds and PAC content (r≥0.98). Considering that BAC with IC values ≤ 50 μg / ml in the DPPH assay refer to active antioxidant’s licorice herb can be classified as a plant with high antioxidant potential. It was found that the iron chelating activity of the G. pallidiflora herb is in direct dependence (r≥0.94) on the content of flavonoids. The obtained results demonstrate the importance of further study of this plant as a source of BAC, including plant antioxidants.

This paper presents the results of the study of lichen flora in swamp complexes of Sakhalin Island, obtained during expeditionary research in 2005–2009 and 2014–2020. The revealed species composition of lichens includes 172 species. The 28 of them are new for Sakhalin and 93 are new for the island swamp complexes. Bryocaulon pseudosatoanum is included in the regional and federal Red lists. Lecidea nylanderi is new to the south of the Far East. The information about substrates, habitats and locations is given for all species. The data on the distribution in the south of the Far East and, in some cases for all Far East, are listed for selected species that are new for Sakhalin Island and the south of the Far East. For the first time, a characteristic of the distribution of lichens in oligotrophic, eutrophic and mesotrophic bogs of Sakhalin Island is given.

Late Pleistocene-Holocene faunal complexes of small mammals (Lipotyphla, Rodentia, and Lagomorpha) from the Russian Far East are described for the first time. We used material from the Medvezhyi Klyk Cave, located in Southern Sikhote-Alin. The numerous fossil findings from the cave display a remarkable taxonomic diversity and high degree of preservation. AMS 14C dating used for determination of deposits age. The Holocene sediments were divided into three periods: Early, Middle, and Late. The Pleistocene deposits age was not exactly determined, but under approximately estimation it can reach 50–60 ka. Thirty-nine species were found, including one member of the extinct genus of arvicolins. There are six faunal complexes identified from the studied Late Pleistocene and Holocene deposits. In general, the faunal complexes characterized by the dominance of Craseomys rufocanus within rodents, Sorex caecutiens within lipotyphlans; and relatively stability composition of most number of the dominant, codominant and subdominant species. Accordingly, the faunal complexes were described by means of two determining criteria only: relative number of species; and presence or absence of certain species. The dominant species are eurytopic and so they cannot use for reconstruction of the paleoenvironment.

The nasocorine plant bug genus Campylomma Reuter from Japan and neighboring regions is reviewed. Twelve species are currently recognized. Several species, which have pale basic coloration, are rediagnosed, with emphasis on the male and female genitalia as significant taxonomic characters. Two new species, C. fukagawai and C. tanakakiana, are described and figured, and C. marjorae Schuh is reported from Japan for the first time and diagnosed. The females of three taxonomically confused species, C. eurycephala Yasunaga, C. livida Reuter and C. lividicornis Reuter, are documented in detail and figured for the first time. Female specimens of the most frequently encountered congeners, C. lividicornis Reuter and C. livida Reuter, can now be unequivocally identified. Confidently associated final-instar immatures are figured for C. aterrima Yasunaga and C. livida Reuter. Confirmed host plant associations are reported for most treated species. Campylomma chinensis [= chinense] Schuh is proposed as a junior synonym of C. livida Reuter, and C. chichijima Carvalho is regarded as nomen dubium. A checklist and a key to species are provided, which are applicable to the faunas of Japan, and of Korea, NE China the Russian Far East and Taiwan as well.

Twenty species of Orthoptera in 19 genera and four families are recorded from the Komsomolsky Nature Reserve for the first time and only four species in two families are found in the wildlife preserve «Udyl». The species riches of Orthoptera recorded from the natural reserves in the Amur Region of the Russian Far East are compared. Number of species in Komsomolsky and Bastak reserves is almost the same (15–20 species), while 51 species of Orthoptera are known from Khingansky Reserve.
