Sinanodonta Woodiana

Here, we present an integrative review of the non-native Sinanodonta spp. from Kazakhstan based on molecular and morphological data. Sinanodonta woodiana (Lea, 1834) inhabits the Syr Darya River, while two species, S. woodiana and S. lauta (Martens, 1877), have established viable populations in the Ili River basin, a tributary of the Balkhash Lake. The latter species was probably introduced in 1961-1971 from the Sungari River, a Chinese tributary of the Amur River. A distribution map of the two Sinanodonta species spreading in Middle Asia is provided. In Kazakhstan and Uzbekistan, these species were recorded from endorheic drainages limiting their native expansion throughout the region, although further human-mediated dispersal events are expected. There are no reliable records of these alien freshwater mussels from Kyrgyzstan, Tajikistan, and Turkmenistan. Our study highlight that Sinanodonta lauta represents one more invasive lineage of the Asian pond mussels and that this East Asian species can successfully colonize plain water bodies of inland desert areas such as Middle Asia.

AbstractGraylings (Thymallus) are among the less well-studied groups of salmonid fishes, especially across their Asian distribution range. Here we perform a comprehensive global review of their phylogeography, systematic diversity and range distributions, including biogeographic reconstruction and assessment of both conservation and taxonomic status of each species. Based on a mitogenomic phylogenetic analysis, three approaches to the delineation of molecular operational units, and evaluation of 15 a-priori defined species, we provide biological support for the recognition of 13 grayling species, plus two additional species tentatively. Several instances of paraphyly and its potential effect on systematic inferences are discussed. Overall, the genus displays increasing species diversity and decreasing range size from higher to lower latitudes and ancestral trait reconstruction supports an East Asian origin for extant diversity, most likely centred in the Amur River drainage. Europe’s colonization by Thymallus took place as early as the late Miocene, at least two colonisations of North America are supported, and multiple dispersal events likely took place into Western Siberia. The conservation status for the 15 taxa was estimated to be: 6 least concern, 1 near-threatened, 2 vulnerable, 3 endangered and 3 data deficient.

The purpose of the article is to analyze the significance of the Amur River transport activity in the 1990s for interregional Russian-Chinese cross-border coopera-tion in the Far East. Using the materials in Chinese as well as archival documents, the author examines the process of border ties resumption between Russia and China in the Far East after the normalization of rela-tions between the countries. The peculiarities of the river fleet functioning on the Amur during the period of socio-economic reforms of the last decade of the 20th century in Russia are studied. The characteristic of the Amur River transport potential is presented. The prob-lems of the Amur River transport in the development of cooperation between the Russian Amur Region and the Chinese province of Heilongjiang in the context of Rus-sian-Chinese relations at the interstate and interregion-al levels are structured.
