High Seismicity

Overwhelming majority of minor, strong and major earthquakes in south Siberia and Russian Far East coincide with relatively narrow intracontinental zones on the boundaries of blocks and lithosphere plates. The geodynamic activity of these zones connects, besides the plate interaction, with deep lithosphere structure and anomalies of the different geophysical fields as well as with blocks’ kinematics. Authors’ located areas of the seismic centers origin and the possible manifestations of the high seismicity based on the distribution of the maximal volumes of releasing seismic energy. We established these areas, with certain care, in the northeast Altai and adjacent part of the west Sayany, in the west of the east Sayany, around the Baikal Lake and in northwest Transbaikalia, in the east of Transbaikalia between the Vitim River and upper stream of the Aldan River, and in the north of the Sakhalin Island. The majority of minor and strong, rarely major, earthquakes took place in these areas. Deep and near surface structural peculiarities influence on these areas’ geodynamics and allow establishing possible levels of seismic energy releasing. We draw areas of intensive seismic energy releasing with its calculating for each from investigated regions. They gravitate towards interblock zones, which separate crust blocks and the North Eurasian Lithosphere Plate. The fulfilled investigation allows establishing specific areas of the increased seismicity in south Siberia, Russian Far East and adjacent territories.

AbstractUmbilicaria orientalis Davydov sp. nov. is described and phylogenetic analysis (ITS, mtLSU and RPB2) confirmed its distinctness and indicated a sister relationship with U. trabeculata within the U. vellea group. The species is morphologically similar to U. vellea but differs by simple, cylindrical or strap-like rhizinomorphs and by thalloconidia, developing both on the lower surface and on rhizinomorphs, that are 1–2 (rarely 4)–celled or in aggregates of up to 5–6 cells. Umbilicaria orientalis is described from the Russian Far East and is currently known from a wide range of localities in East Asia, from the Far East to South Siberia and Mongolia in the north, to Hebei and Tibet in the south. New sequences of U. americana were obtained; the species represents an independent phylogenetic lineage within Umbilicaria subg. Papillophora. Diagnostic traits and variability of different developmental stages of U. orientalis, as well as its East Asian distribution pattern, are discussed.

Plants diversity and riches of specific floras in the Russia’s Far East is determined not only and not somuch by a modern ecotopes diversity, as by the expression in the stale of the limit of permafrost soils, by the spread ofconsolidated boreal-nemoral ecosystems, by the situation of the Holocene boundary, ancient and early Holocene, presenceof the "small" and “big” migratory ways promoted the savings of a vascular plants diversity (RSR) by all praterritory, andthe “bridges” of a land. These bridges provided, first, resettlement of plant species from the West in dry late Pleistocene,updating of floras by Daurian-Mongolian steppe species, secondly, by returning of the species lost in the cold periods dueto their migration from the south, from refuges, by presence of refuges from fire, and elementary pyrogenic degradationof flora and vegetation reduces RSR on the order. However to the north from 50º N. L. on continent and Sakhalin islandand with 46º N. L., from Urup island on the Greater Kuril Islands refuges and isolates for maintenance high RSR has novalue or even it reduces, preserving more cold-resistant and cold-loving flora. Poverty of flora of coasts of KamchatkaPeninsula is connected with this phenomenon.

Because of its energy reserves and long history of economic links with North Korea, the Russian Far East could provide useful incentives needed to help convince Pyongyang to abandon its nuclear program. For this reason, the United States should begin crafting a regionally based strategy that includes Russia.

Gram-negative bacteria belonging to the order Rickettsiales such as Anaplasma, Ehrlichia, Neorickettsia, Rickettsia, and Orientia are the causative agents of infectious diseases collectively known as rickettsioses. Of the different rickettsial diseases, spotted fever and scrub typhus have ravaged India for the past couple of centuries. Specifically called the Indian tick typhus, spotted fever was discovered in India in the latter half of the 19th century. After several decades of dormancy, the disease re-emerged in several parts of India. Scrub typhus, originally discovered in Japan, has been recognised to be endemic to a so-called Tsutsugamushi Triangle, extending from Russian Far East and Korea in the north to northern Australia in the south and Afghanistan in the west, but the geographical description has now been breached. Not only in India, scrub typhus has emerged as the leading infectious disease in all endemic areas. Almost all Indian states have records of recurrent outbreaks. Infection can be of dire consequences, as multi-organ dysfunction and neurological disorder (meningocephalitis) are the common complications. This article discusses the historical background and scientific reports of rickettsioses in India.

Currently, invasive species spreading is becoming a key problem on the global scale. Scope of invasive species control get solved at governmental level in many countries; hundreds of billions dollars a year are allocated as financial support; global programs are created. For the first time, biological control of invasive species Ambrosia artemisiifolia using an introduced phytophage insect was applied in Russia (former USSR) in the 60-70s years of the 20th century and it remains a unique large-scale example until to nowadays. Ambrosia leaf beetle (Zygogramma suturalis (Fabricius, 1775) was brought to the Russian Far East for biological control of Ambrosia artemisiifolia in the 80-90s years of the 20th century for the first time, however the targeted result was not achieved. At present, Zygogramma suturalis were adapted at the Primorskii Krai in the south of the Far East, but due to climatic conditions its numbers are low and, as a result, the impact on ambrosia is minimal. The search for native insect species with capable of effectively suppressing the spread of aggressive quarantine weed in local conditions remains in the area of focus. At the moment, two species of native leaf beetles have been identified, using Ambrosia as an additional element in the diet. Climate changes and the shift of biogeographic boundaries cause the natural expansion of the areals of some East Asian insect species to the north within the Russian Far East. Bug-edge Molipteryx fuliginosa (Uhler, 1860) is one of such species. Expanding the area to the north and east, the species also corrects trophic preferences. As a result of our research in the south of Primorskii Krai, the trophic relations of Molipteryx fuliginosa were studied in the field conditions and in rearing cages. The same work was carried out in places where Ambrosia artemisiifolia were growing in a great number. For insects observing were used standard methods. As a result, firstly was established and confirmed that the bug-edge uses Ambrosia artemisiifolia as a feed plant only in select developmental stages, including imago. The feeding of larvae of IV – V ages was noted in natural conditions. The long-time Molipteryx fuliginosa development cycle on ambrosia leads to break the course of normal plant ontogenesis and causes wilting of individual organs.

Runs and escapements of sockeye salmon to the Zhupanova River have increased since 1985 with the run of 10.63 . 103 ind. instead of 1.45 . 103 ind. in 1960–1984, on average. The increasing was reasoned by change of the pink salmon odd year-classes domination in West Kamchatka to domination of even year-classes after the extremely high escapement in 1983. In 2005–2006, the sockeye salmon stock in the Zhupanova River became even more higher that continues till nowadays (runs of 68.20 . 103 ind. in 2005–2017, on average). This growth corresponds with general increasing of the pacific salmons abundance in the Russian Far East as the result of favorable environmental and feeding conditions in the North Pacific. General biological indices (age, body length and weight, maturity, fecundity) of mature sockeye salmon originated from the Zhupanova River are presented on the data of commercial catches in the sea in 1999–2017. The sockeye salmon population from this river has 11 age groups. The age group 1.3 is the most abundant and associated with the age groups 1.2 and 1.4. Majority of sockeye in the catches from the Zhupanova has the age 1.3 (on average 66.2 % in 1999–2017). Besides, returns of underyearlings with age 0.2, 0.3, and 0.4, and the fish with age 2.2, 2.3, 2.4, 3.2, and 3.3 are detected. The body length and weight are similar for all age groups of sockeye salmon: for males/females the mean length is 57.56/57.70 cm, mean weight is 2.69/2.62 kg. The mean males:females ratio is 44.7 : 55.3. The mean absolute fecundity is 4121 eggs. In opposite of sockeye salmon in some rivers of East Kamchatka, the population of the Zhupanova has no negative year-to-year trend of the body length or weight.
