Species List

In Commander Islands, the peculiar geographic location, hydrology and geomorphology contributed to de-velopment of a very peculiar algal floristic complex. First scientific information on species composition in this region appeared in XIX century. In this revision, we analyzed scientific publications containing algal floristic information from this region and composed list of species recorded during 1889–2020. We provided information about 52 green and 55 brown algal species recorded from the Commander Islands. The infor-mation concerning representatives of Laminariales is discussed in details, as they form basis of the underwa-ter vegetation. Our species list includes citations of references containing records from the Commander Is-lands and brief description of their biological and morphological characteristics. As we noted, in Russian Far East, Commander Islands belong to one of the few regions with highly examined algal flora.

Complete Study

We present results of revision based on our personal data and reports published from 1889 to 2020 on the red algal species composition from the Commander Islands. The general list includes 150 species. Six species are reported for the first time, including Phymatolithon lamii, Neoabbottiella valentinae, Callophyllis beringensis, Kallymeniopsis verrucosa, Velatocarpus kurilensis, and Mazzaella hemisphaerica. These species are illustrated by photographs of samples collected by us from Bering Island in September 2020. Another 15 red algal species reported from this area by different authors we attributed by us to doubtful and incorrectly identified taxa. The list of valid species is organized similarly to that in our recent paper on flora of the green and brown algae from the Commander Islands [Klochkova et al., 2020]. In the list, we cite papers containing information on species records from this area. For all species, information on their distribution frequency, depth, and some ecological and biological features are provided. It is shown that in contrast to many other regions of the Russian Far East, the Commander Islands are well studied from phycological and floristic aspects. This is due to seasonal and year-round investigations carried out in this region in different time periods, a thorough diving survey on the coastal area and more complete study on microepiphyte species composition, including microscopic red algae.

A new species of scincid lizard allied to Plestiodon japonicus (Peters, 1864) was described as P. finitimus sp. nov., fromthe eastern part of Honshu and Hokkaido, Japan. A previous DNA study reported the taxonomic status of the easternJapanese populations of Plestiodon as an undescribed species on the basis of their collective genetic distinctness from aparapatric congener P. japonicus sensu strict from the western part of mainland Japan. We present the diagnostic featuresof P. finitimus compared to P. japonicus and P. latiscutatus Hallowell, 1861, the other parapatric species occurring in theIzu Peninsula and Izu Islands of central Japan, on the basis of morphological characteristics and DNA barcode patterns.Both P. finitimus and P. japonicus have a small postnasal and large anterior loreal that contacts the supralabials. In contrast,the Izu Peninsular populations of P. latiscutatus, which had no known diagnostic features relative to the other two species,usually have a large postnasal and small anterior loreal, with the latter separated from the supralabials by the former, ormay otherwise lack a postnasal. In most populations of P. finitimus, the right and left prefrontals are usually isolated fromeach other, whereas they exhibit medial contact in most populations of P. japonicus. Although all the above characters arevariable both within and between populations, 60–90% of the specimens from each locality on mainland Japan werecorrectly identified using a combination of these characters. Based on these characters, the Russian Far East populationof Plestiodon was also identified as P. finitimus. The interspecific sequence differences in the standard DNA barcoderegion (a 658 base pair fragment of the cytochrome c oxidase subunit I gene of mitochondrial DNA) were distinct, andeach of the three species was exclusively clustered in a neighbor-joining tree. The limited hybridization among the threespecies indicated by previous studies suggests that DNA barcodes could provide a reliable key for their correctidentification. The implications for the biogeography and speciation of the three parapatric lizard species are briefly discussed.

Abstract In the south of Russian Far East Amorpha fruticosa (Fabaceae Lindl.) is used as ornamental plant. It actively blooms and fruits here and successfully spreads by suckers, rarely by seeds. There are another ways of Amorpha fruticosa application in Primorsky Krai – as melliferous and technical plant for reclamation of disturbed lands and formation of protective field belts. These activities requires a great amount of quality seeds and, in turn, investigation of Amorpha fruticosa seed propagation. The study of the morphological characteristics of fruits from 12 different places in the Primorsky Krai showed that the linear characteristics of the fruits have minor differences but length of racemes and seed germination vary greatly. The longest racemes are detected in the city of Bolshoy Kamen (17.8 cm), the shortest ones – in Nekruglovo settlement (12.7 cm). The largest fruit number has racemes from Partizansk city (152). The weight of 100 fruits varies from 1.16 g (Kraskino settlement) to 0.94 g (city of Bolshoy Kamen). Highest germination capacity is observed in plants at Lake Soldatskoe (91%), the smallest in plants from Strugovka settlement and the city of Bolshoy Kamen (43%). Absence of germination of seeds from Vadimovka settlement is probably caused by pest – American seed beetle, Acanthoscelides pallidipennis.

Noise Statistics

A new technology for predicting strong earthquakes with a magnitude range of Mw about 7 and more is considered, based on the use of continuous recordings of seismic noise on a network of 21 broadband stations of the GS RAS in the region of the Kamchatka Peninsula, the Commander Islands and the Paramushir Island. The article is described a forecasting algorithm created by A.A. Lyubushin, IPE RAS, and the state of its implementation in the Kamchatka Division GS RAS for the purpose of an advance (months - first years) assessment of the strong earthquakes preparation sites. The data processing algorithm includes the calculation of four noise statistics time series for each station and the construction of their spatial distribution maps for different time intervals. We used four noise statistics, including the minimal entropy of the orthogonal wavelet coefficients squares and three characteristics of the multifractal spectrum of singularity – the generalized Hurst exponent, the carrier width, and the spectral wavelet exponent. Based on previous research, characteristic features of the four seismic noise statistics behavior at preparation stages of the local earthquakes 2013-2016 with Мw=6.6-8.3 were revealed, corresponding to similar changes before the two earthquakes with Мw=8.3 and 9.0 in Japan. It was found that an increase in the danger of a strong earthquake is accompanied by an increase in minimal entropy and a decrease in the carrier width and other parameters of the singularity spectrum. Since 2020, the processing of current data from the network of broadband stations of the GS RAS in the Far East region has been carried out in accordance with the seismic forecasting algorithm for drawing up quarterly forecast conclusions, which are sent to the Russian Expert Council on Earthquake Forecasting, Seismic Hazard and Risk Assessment (REC) and to Kamchatka Branch of REC

Представлена научная биография геолога Эдуарда Эдуардовича Анерта (1865–1946), внесшего огромный вклад в геологическое исследование российского Дальнего Востока и северо-восточного Китая. В 1895 г. он начал исследования вдоль Транссибирской магистрали, а позднее продолжил их в Приморье, на Сахалине и в Маньчжурии. Анерт основал Дальневосточный геологический комитет, организовал комплексное изучение минеральных ресурсов региона. Эмигрировав в Китай, он продолжил исследования в районах, прилегающих к Китайско-Восточной железной дороге, стал соучредителем Общества изучения Маньчжурского края и его музея (ныне – музей Хэйлунцзянской провинции). Результатом его многолетней деятельности на Дальнем Востоке стала публикация более двухсот научных трудов, многие из которых не потеряли актуальности и сегодня. В статье использованы материалы архивов и библиотек США и Китая. This article presents the scientific biography of the geologist Eduard Eduardovich Ahnert (1865–1946), who contributed much to the geological research in the Far East, both Russian Far East and the Northeast China. Having begun his research along the Trans-Siberian Railway in 1895, he continued his work in Primorye, Sakhalin, and Manchuria. Ahnert established the Far Eastern Geological Committee and succeeded in organizing a comprehensive study of the regional mineral resources. Having emigrated to China, he continued his research along the Sino-Eastern Railway, became a co-founder of the Society for the Study of Manchuria and its museum (now the museum of the Heilongjiang Province). His multi-year activity in the Far East resulted in more than two hundred scientific publications, many of them have not lost their relevance today. Writing the article the author used materials from foreign archives and libraries of USA and China.
