Indigenous people are often depicted as helpless victims of the forces of eighteenth and nineteenth century colonial empire building: forces that were beyond their understanding or control. Focusing on the story of a mid-nineteenth century diplomatic mission by Sakhalin Ainu (Enchiw), this essay (the first of a two-part series), challenges that view, suggesting instead that, despite the enormous power imbalances that they faced, indigenous groups sometimes intervened energetically and strategically in the historical process going on around them, had some impact on the outcome of these processes. In Part 1, we look at the story of one Sakhalin Ainu family over multiple generations in order to highlight the strategic place of the Sakhalin Ainu in cross-border relationships – particularly in the relationship between China and Japan – from the early eighteenth to the mid-nineteenth century.

In Part 2, we look at the Nayoro Ainu elder Setokurero’s intervention in imperial negotiations between Japan and Russia in the early 1850s, and consider what impact this may have had on the experiences of Sakhalin Ainu during the early phases of Russian and Japanese colonial rule in Sakhalin.

Podocotyle is a genus of marine opecoelid digeneans that parasitize a wide variety of fish as adults. We present the first phylogenetic analysis of several Podocotyle isolates using nuclear 28S rDNA and mitochondrial cox1 DNA regions. New sequences were obtained for Podocotyle specimens from fish caught in the Sea of Okhotsk and the White Sea. Based on morphological and molecular data, eight Podocotyle lineages of species rank were revealed. However, this diversity is poorly formalized within the current taxonomic model of the genus. As a result, we identified Podocotyle cf. angulata, Podocotyle cf. atomon, Podocotyle cf. reflexa, Podocotyle atomon of Sokolov et al., 2019, Podocotyle sp. of Denisova et al., 2023, Podocotyle sp. 1, Podocotyle sp. 2 and Podocotyle sp. 3. We also highlight the unresolved question of the life cycles of representatives of Podocotyle whose intramolluscan stages parasitize the intertidal snails Littorina spp.

An expanded description of a little-known arctic species Montacuta spitzbergensis from the Sea of Okhotsk with new data on its morphology, ecology and geographical distribution is given. This is the first record of M. spitzbergensis from the north-western Pacific. It differs from other species of Montacuta in its large (to 8.4 mm), elongate–ovate, thick shell with wide, slightly curved hinge plate, wide, short, and shallow resilifer, and weakly developed external ligament. This species occurs in the Arctic Ocean (Spitsbergen, Barents, Kara, Laptev and Chukchi Seas) and the Pacific Ocean (Sea of Okhotsk) at depths from 9 to 232 m at a bottom temperature from −1.62°C to +2.50°C. The hinge structure of the type species of the genera Montacuta and Tellimya is also discussed.
