To determine whether modern theories predict snail growth responses to trematode infestation a field growth study of Onoba aculeus, Littorina saxatilis and L. obtusata infected with two closely related Microphallidae trematodes was conducted in the White Sea. In each of the three host–parasite combinations studied trematode infection causes inhibition of snail reproduction. However, contrary to the classical interpretation of the gigantic growth of infected snails as a side effect of parasitic castration, the presented study failed to demonstrate that Microphallus piriformes causes gigantism in Littorina. The infection tended to stunt growth in L. obtusata and had no significant effect on growth rate of L. saxatilis. In contrast, gigantic growth was observed in O. aculeus infected with M. pseudopygmaeus. Considering that both trematode species are very similar biologically, the discrepancy is attributed to differences in the life history of the snail's hosts. Onoba aculeus is a relatively short-lived snail (2.5–3 y). The lifespan of L. saxatilis and L. obtusata is much longer (up to 9–11 y). These findings agree with a previously reported ‘energetic’ hypothesis that predicts growth alterations in accordance with life history variations of the snail species.

This article is based on the fi eld work data of Pushkin House related to the history of the Anoufrievsky Skete that existed at the Winter Coast of the White Sea in the 18th — early 20th centuries. Specific storylines and motives are discussed, selected by the authors from the body of the recorded narratives concerning the Skete. The locals reproduce the historical narratives, including the legendary tales about the fi rst settlers, the life of the Skete community, the Old Believers’ wealth, recombining the history of the site in various ways; eschatological motives are superimposed on the speculations concerning the decline of the Pomor villages.

The article reconstructs the biography of a little-known Ukrainian poetess Lada Mogylianskaya and the history of her relationship with M. Gorky; fragments of her poems in Ukrainian and Russian are given. Mogilyanskaya was first repressed in 1929 in the case of the Ukrainian “Democratic Union”, passed through the Solovetsky prison, D.S. Likhachev. Subsequently, she ended up at the construction site of the White Sea-Baltic Canal, was released ahead of schedule and received an award sign. From 1934 she worked in the cultural and educational department of the Dmitrov prison and on the construction of the Moscow — Volga Canal. M. Gorky repeatedly took part in the fate of Mogilyanskaya, appealing to high-ranking officials and petitioning to alleviate her fate. In 1937, after the arrest of G.G. Yagoda and the head of Dmitlag S.G. Firin, she was repressed a second time and died. The article also examines the work of the cultural and educational departments of the GULAG, in which representatives of the creative intelligentsia could escape from overwhelming, destructive labor. For the first time, the article introduces into scientific circulation M. Gorky's letters to various persons related to the fate of the poetess, letters to him from the Ukrainian philologist M.M. Mogilyansky, poet S. Marshak and other documents stored in the A.M. Gorky’s archive in Moscow.

This paper demonstrates the results of diatom analysis of the Holocene sediments from the southeastern part of the Tersky Coast of the White Sea. The main subject of the study is the diatom assemblages’ concentration and composition, as well as the ratio of the main diatom ecological groups in sediments. The study sites were located on the Tersky Coast from the village Chavanga to the right coast of the Varzuga River, at heights from 17 to 52 m. Our reconstruction of the Tersky Coast of the White Sea development is based on diatom study of Holocene sediments from three cores. Age was determined according to radiocarbon dating. In this work, the author determines the features of environmental development, starting from the first half of the early Holocene, clarified the age of the main transgressive stages - Folas, Tapes, Trivia and the absolute heights of their marine sediments. According to the changes in concentration and composition  of the main ecological groups of diatoms, the author records the significant trends in the water temperature changes in coastal reservoirs and hydrobiological conditions in the Holocene, such as short-term decrease in the temperatures of the end of Boreal and the first half of Atlantic time, the Holocene hydrobiological optimum, and changes in temperatures of the Subboreal and Subatlantic time.

The article deals with the toponymy of the Karelian Pomorje of the XVI-XX centuries, extracted from written monuments, documents of the National archive of Karelia and topographic maps. These materials, which contain the names of haymaking and fishing grounds, saltern and other objects, are a valuable source for studying the history of the village of Keret' and the entire Karelian coast of the White sea. Based on ethnographic, historical and toponymic data, it is possible to identify evidence of the existence of reindeer herding in this territory in the past (before the 17 th century).
