The Amur River

The article is based on a long-term study of floodplain soils of the Amur River valley within the north-eastern part of the Middle-Amur Lowland. The results of field work on the soil-geomorphological profile across the Slavyansky Island, located 200 km from Khabarovsk down the Amur River, are discussed. The study analyzes the occurrence of the island's floodplain soils on riolkas[1] and their properties, with an emphasis on morphology and lithological and particle-size composition. The features of soil formation on riolkas of different genesis – alluvial and aeolian – are shown. On sandy and sandy-loam deposits of alluvial riolkas (“meadow-forest” ridges) poorly developed sod gley soils are formed. On heavy loam and clay alluvium of the “meadow“ ridges, annually flooded by river waters, sod-meadow gley soils develop under the woodreed grass stand. Sand deposits of high aeolian riolkas are characterized by a homogeneous fine-grained structure without interlayers, signs of organic matter and with a significant amount of mica. They describe poorly developed sod-forest soils under high-trunk oak forests. The formation of texture-differentiated soils on all types of riolkas was not revealed. When the floodplain reaches the position of the first terrace above the floodplain, the differences in the lithological composition and particle-size distribution, soil texture, height above the water edge and the nature of vegetation on the inherited riolkas provide a multidirectional evolution of soil formation. At the same time, the development is taking place in accordance with the zonal types of soils (sod-forest, brown-earth, texture-differentiated – soil with a bleached horizon (podbel)). The last are mainly formed on clay-loam alluvium, which can overlay not only alluvial, but also some aeolian riolkas. [1]Riolkas are ancient, relatively high sand ridges (extended dunes) with plant cover found in Amur region (Russian Far East).

A long-term study implemented in the Amur River basin enabled us to generate an updated checklist of 606 valid species in Chironomidae (Diptera) which are composed of 129 genera and six subfamilies, with 98 (17%) described new species belonging to 46 genera. Among the 98 recently described species, 46 ones (45%), were considered as possible endemics and sub-endemics. The numbers of species and genera by subfamilies is as follows: Podonominae (3 species; 3 genera), Tanypodinae (17; 9), Diamesinae (25; 11), Prodiamesinae (7; 3), Orthocladiinae (307; 57) and Chironominae (247; 46). The higher numbers of species (421 and 410, respectively) were recorded in the Lower and Middle parts of the Amur River basin, as compared with the Upper part of the basin. Most of the recorded chironomids (387 species, 67%) are Palaearctic in distribution, while others (191, 33%) are widely Holarctic. Species with Palaearctic distribution mostly have the following range types: East Palaearctic continental (23%); East Palaearctic continental-insular (20%); Palaearctic transpalaearctic (14%); Palaearctic amphi-Eurasian (10%).

The earliest pottery from the Russian Far East, Osipovka and Gromatukha cultural complexes, was radiocarbon-dated to c. 13 300–12 300 BP. In Siberia, the earliest pottery is known from the Ust-Karenga complex, dated to c. 11 200–10 800 BP. The Osipovka and Gromatukha complexes belong to the Initial Neolithic, and they are contemporaneous with the earliest Neolithic cultures in southern China and Japan. In spite of the very early emergence of pottery in the Russian Far East, there is no evidence of agriculture at the beginning of the Neolithic, and subsistence remains based on hunting and fishing, including anadromous salmonids in the Amur River and its tributaries.

Radiocarbon Chronology

The radiocarbon age of the earliest pottery from Russian Far East—Gromatukha and Osipovka cultures—is between around 13,300 BP and around 10,400 BP. This shows that the Amur River basin was one of the centers of origin of pottery in East Asia, at the end of the Pleistocene. Today, there are three areas within East Asia with pottery-associated 14C dates between around 14,000 BP and 13,000 BP—southern China, the Japanese Isles, and Russian Far East.

The Russian Far East

For the Russians, Siberia has always been “Other” and, as a result, it has often been imagined as something other than what it is. As Mark Bassin argues in this richly detailed book, this habit of the Russian imaginaire was on full display during the mid-1800s when hopeful Russian observers and statesmen envisioned the Russian Empire's latest territorial acquisition—the Amur river in far eastern Siberia—as a new Mississippi and the region around it as a potential second America. Ultimately, of course, these geographical analogies proved well off the mark. The region of the Amur never went on to experience the prosperity of the United States and the Amur river never even remotely rivaled the importance of the Mississippi as an artery of trade and settlement. And what is so interesting about all this is that the Russians themselves began to have their doubts about the Amur within just a few years of annexing it. Bassin's work, in fact, concentrates on explaining this strange shift. It is a study of why the Russian vision of the Amur that began so hot ended up turning so cold so quickly and what the vision itself seems to reveal about the content of Russian national identity.

The family Micronoctuidae and the genus Micronoctua Fibiger, 1997 are reported from the Russian Far East and neighbouring countries for the first time. The family is represented in the region by two species in the genera Mimachrostia Sugi, 1982 and Micronoctua both occurring in Russian Far East, Korea, China and Japan. The northern distribution limit of the family Micronoctuidae is the middle of the Amur River (50°31΄N, 137°035΄E), reached by Mimachrostia fasciata Sugi, 1982. The new species, Micronoctua occi, sp. n. is described from Russian Far East, the Korean peninsula, China and the Tsushima Islands of Japan. The male and female genitalia are illustrated and compared with those of Micronoctua karsholti. Distribution maps for the two species are presented.

New finds of seven East Asian Lepidoptera species in the Russian part of the southern Priamurye (Amur Basin area) are presented. Lobocla bifasciata (Bremer et Grey, 1853) (Hesperiidae), Acosmeryx naga (Moore, [1858]) and Rhagastis mongoliana (Butler, [1876]) (Sphingidae) were found in the Amur Oblast’ for the first time. Ambulyx tobii (Inoue, 1976) (Sphingidae) was first discovered in the Khabarovsk Kray; it was also found in the Chernigovsky district of the Primorsky Kray, northward from the previously known localities. New finds of very rare nemoral species, Chrysozephyrus brillantinus (Staudinger, 1887) (Lycaenidae) and Clanis undulosa Moore, 1879 (Sphingidae), in the Khabarovsk Kray are reported. It is shown that the subtropical and tropical species Siglophora sanguinolenta (Moore, 1888) (Nolidae), first collected in Russia in 2020, has successfully naturalized in the southern Khabarovsk Kray. New finds of these species indicate that the species have extended their ranges northward and naturalized in new areas. This has occurred due to climate changes in the Amur River basin over the past decades such as the rising average annual and average air temperatures during cold periods.

Morphna paleo sp. n., the earliest winged representative of any living cockroach genus and the earliest representative of the family Blaberidae, is described from the Danian Arkhara-Boguchan coal mine in the Amur River region (Russian Far East). The branched Sc and A suggest Ectobiidae (=Blattellidae) probably is not the ancestral family because Blaberidae were derived directly from the extinct family Mesoblattindae. The associated Danian locality Belaya Gora yielded Ergaula stonebut sp. n., the earliest record of the family Corydiidae. Both species belong to genera codominant in the Messel locality, thus validating their dominance in early Cenozoic assemblages.
