Naukan ethnobotany in post-Soviet times: lost edibles and new medicinals

Background This study focuses on health-related plant use among speakers of the critically endangered Naukan language (Inuit-Yupik-Unangan family) in the Russian Far East. The Naukan people were forced, in 1958, under Soviet consolidation, to move from their original settlement on Cape Dezhnev, leading to significant changes in spiritual worldview, subsistence, social structure, and language proficiency in the years that followed. Here, we focus on changes that elders report in their edible, medicinal, and spiritual uses of local plant species since their childhood. Methods The authors worked from 2014 to 2016 in the villages of Lavrentiya, Lorino, and Uelen, in the Chukotskiy district of the Chukotka autonomous region, directly adjacent to the Bering Strait. We conducted structured interviews, using an oral history approach, along with participant observation and collection of voucher specimens from the local arctic tundra. Those with Naukan names and uses represent 42 species in 25 families. Results Participants reported a decrease of 13% in the number of edible species that people currently harvest, from what they recall harvesting in their youth. On the other hand, the number of local species considered to be medicinal has actually increased by 225%. Current and past Naukan medicinal practices diverge in some notable ways from those of neighboring societies on the Alaskan side of the Bering Strait. Most of the spiritual significance of local plants species is remembered by only a few elders. Conclusions Naukan elders explained the large increase in use of medicinal plants by noting that their original concept of medicine emphasized prevention and that illnesses were often assigned a spiritual rather than physical cause. Increased integration with ethnic Russians after moving from Naukan led to the adoption not only of new plant uses, but also of an entirely different, more naturalistic way of viewing illness and treatment.


Introduction
Despite the harsh arctic climate of Chukotka, a region in the far northeast of Russia (Fig. 1), plants have played an important role in the subsistence and medical practices of local native peoples [1][2][3]. This is true not only in the short summer growing season, but also throughout the year, due to storage techniques including drying, fermenting, and soaking in animal fat [3,4].
The earliest glimpses of this region's ethnobotany can be found in Frans Reinhold Kjellman's work with the coastal Chukchi in 1878-1879 [5,6]. Bogoraz [7,8] also provided some information on plant use in his more general ethnographic accounts. The Soviet period brought some more focused work on local plant uses. Notable studies include Tixomirov's [9] and Menovshchikov's [10] description of Chaplinskiy Yupik plant uses and Sokolova's [11] and Mimykg Avtonova's [12] work on Chukchi ethnobotanical practices. However, there are important gaps in the knowledge [2,3] of this region, and documenting the continuing importance of plants to these societies in the post-Soviet context [1,13] is especially urgent. One notable recent study [14] has compared attitudes toward edible fungi among the Siberian Yupik (Chaplinskiy and Naukan) and Chukchi in Chukotka and the Iñupiat on Alaska's Seward Peninsula.
In particular, there has been very little ethnobotanical work done with speakers of Naukan (Inuit-Yupik-Unangan family) [15]. Dobrieva et al. [16] listed names for plants in their Naukan dictionary. Mimykg Avtonova [12] and Menovshchikov [10] documented some uses of edible species within larger studies. In the broader ethnomedical perspective, Bogoraz [17] and Tein et al. [18] explained the spiritual beliefs and healing practices of the Chaplinskiy Yupik and Naukan in the first half of the twentieth century. However, this article represents the first published work focusing specifically on ethnobotany of the Naukan people.

History of the Naukan
The village of Naukan (originally called Nevuqaq) (Fig. 2) was built on Cape Dezhnev, at the extreme eastern end of Eurasia. Subsistence practices focused on hunting sea mammals including the gray whale (Eschrichtius robustus), walrus (Odobenus rosmarus), spotted seal (Phoca largha), and bearded seal (Erignathus barbatus). This was supplemented by hunting of land mammals and gathering of plants and smaller marine organisms. During the Russian Imperial and early Soviet period, the site served as an important center for commercial and cultural exchange between the Chukchi on the Russian side and the Iñupiat on the Alaskan side of the Bering Strait. Intermarriages were common between the people of Naukan and the islands of Big and Little Diomede, in the Russian and US territories, respectively [16].
In 1958, the Soviet government closed Naukan as part of a larger program of consolidation of local population centers, and residents were forced to move to the neighboring Chukchi villages of Nunyamo and Uelen. Nunyamo, in turn, was closed in 1977, and local people moved from there to the villages of Lavrentiya and Lorino, where most reside today.
Following relocation, the Naukan people and their culture experienced significant changes in spiritual worldview, subsistence practices, social structure, and language proficiency. Waves of military and civilian migrants from other parts of the Soviet Union also contributed to these broad changes through direct personal interaction, including intermarriages. Although Naukan people did not experience the acculturative influences of missionary activity that were widespread on the Alaskan side of the Bering Strait, shamans were persecuted and the accompanying spiritual practices were greatly challenged by the dominance of materialism under Soviet rule [19].
The period immediately after the collapse of the Soviet Union, particularly the second half of the 1990s, was also quite difficult for the study region, as economic support from the central government was withdrawn. One result was the revival of sea mammal hunting brigades to meet the nutritional needs of local people, who were left with very little food in village stores [20]. The economic situation has improved somewhat in the last decade. Currently, the Naukan language is considered critically endangered [21], a designation meaning that only some members of the oldest generation speak it.

Methods
The authors conducted work from 2014 to 2016, principally in the villages of Lavrentiya, Lorino, and Uelen, in the Chukotskiy district of Chukotka, Russia (Fig. 1). The study also included a few interviews with Naukan speakers in the regional capital of Anadyr and two in the  Alaskan towns of Nome and Kotzebue. All study sites have arctic tundra vegetation. The village of Naukan and the area immediately around it are dominated by noncarbonate mountain complex tundra with nearby regions of low shrub and wetland tundra [22] around neighboring villages.
The research was part of a larger study comparing the plant traditions of cultures on the Alaskan and Russian sides of the Bering Strait, funded by NSF grant number 1304612 [3]. The goal of the project was to document and compare edible, medicinal, and spiritual plant use among the Naukan and Chukchi peoples of Chukotka, Russia, and the Central Alaskan Yup'ik. Human subjects approval was obtained from the University of Alaska, Fairbanks Institutional Review Board (IRB), prior to beginning work. The study conformed to the American Anthropological Association's ethical guidelines [23], and prior informed consent was given by all participants.
We began in each village by meeting with local community members to answer questions, discuss the research goals, and recruit potential participants. Since Naukan is a critically endangered language, we attempted to interview as many speakers as possible, rather than aiming for a representative sample. Dorais [24] estimated the number of speakers as 60. However, our detailed discussions with elders, asking them to freelist every speaker they know, yielded a more conservative figure of 29 individuals. We succeeded in interviewing 21 (76%) full speakers and an additional seven partial speakers.
Interviews focused on local plants used presently or in the past for nutritional or health-related purposes. For each species, we asked participants to freelist edible, medicinal, and spiritual uses as well as times and methods of harvest, preparation, and storage. For every use given, we also asked the following: (a) if it was practiced during the participant's youth and (b) if it is currently practiced.
A number of researchers [25][26][27] have found oral history to be a useful approach in achieving a time depth in ethnobotanical studies, particularly when there are no suitable past studies or archival records to use for comparison. To help mitigate potential weaknesses of oral histories [28,29], including selective or inaccurate memories of past events and practices, researchers often combine this method with other approaches. For example, oral history has been corroborated with linguistic evidence [30,31] and comparative ethnography [32][33][34]. For the current analysis, we use evidence from Soviet popular literature [35][36][37][38] to support claimed borrowings. Reports from neighboring indigenous groups [39][40][41] lend credibility to accounts of discontinued uses.
Naukan participants gave a name or use for 39 local plant species, in 22 botanical families and three algae species in three families. Vouchers of these are stored in the herbarium of the Komarov Botanical Institute in St. Petersburg, Russia, and were determined there with the help of botanist Vladimir Razzhivin. We compiled a list of 42 Naukan folk genera [42], including nine whose botanical identity is not still remembered. All but one of these are monotypic. In this article, we focus on those species that study participants considered to be important for human health and nutrition. Table 1 includes those Naukan names whose botanical identity is known and summarizes their uses. Although the major focus of this article is on plants with healthrelated uses, we considered it important to list others here as well, due to the dearth of published literature [15] on Naukan ethnobotany. Algae species are included, since local people group these with plants [1,2,43] in their folk taxonomy. We do not consider fungi, however, as Yamin-Pasternak [14] has already made a thorough treatment of that subject. Russian names are those used by local people for these species. The same names may refer to different species in other parts of Russia.

Results and discussion
The focus here is on how the overall importance of species has changed over time. For the purpose of calculating use values (UVs) [44], we included only data from the 21 members of the oldest generation (ranging in age from 62 to 91), who remember the period before and immediately after the forced move from Naukan in 1958. However, interviews and participant observation with younger people did help to confirm whether the uses that elders described should be considered currently practiced or not. Table 2 presents changes in gathering and use of edible plants from elders' oral histories. Our extensive participant observation in summer field sessions from 2014 to 2016 also helps confirm which plants are still collected and prepared. The total number of edible species is 26. This is roughly comparable to what has been reported for neighboring societies (Fig. 1). For example, Kjellman's pioneering work [5]  As expected, the number of species gathered for food has decreased after integration with ethnic Russian neighbors and greater access to store-bought food. Of 26 total edibles, 19 (73%) have been retained from the days of elders' youth. Two (8%) were adopted more recently, while five (19%) were discontinued. Some species in the Local accounts of the six discontinued edible species can be backed up using comparative ethnography. Here we cite reports of their use in neighboring societies and by other arctic peoples. The Central Alaskan Yup'ik [41] have harvested tubers of Claytonia tuberosa Pall. ex Schult. as well as leaves and flowers of the dwarf willow (Salix) species for food. Residents of King Island [39], in the Bering Sea, used to gather Claytonia acutifolia Pall. ex Schult. tubers and Anemone sibirica L. flowers. Egeland et al. [40] report that the Iñuit of Baffin Island eat the flowers of Saxifraga oppositifolia L.
For the 19 maintained edible species, there has also been an increase, in 14 cases (74%), in the ways they are prepared. Eleven of that group (79%) have acquired new uses, principally, from ethnic Russians. For example, wild greens are now added to soups such as borsch and the cabbagebased shchi, as well as eaten in the traditional manner with seal oil. Berries are now made into jams, kompot (stewed fruit), and mors (fruit drink). For three species, the new uses came from Chukchi neighbors [3]. For example, Naukan people traditionally fermented the leaves and stems of rose root (Rhodiola integrifolia Raf.) by itself. Now some people add the flowers of Pedicularis verticillata L. or the leaves of Rumex arcticus Trautv. as well. Table 3 discusses past and present medicinal uses. Of 13 total species in this category, Naukan elders said nine (69%) are new additions since their youth and that none has been lost, leaving four (31%) with maintained use over that period. Although past studies [25,49,50] have demonstrated the importance that borrowed species and uses can play in local pharmacopeias, the Naukan elders' claim to have previously used so few species medicinally  Tuber 0 0.14 -Eaten raw with seal oil -Polygonaceae and to have borrowed such a large proportion of the uses they currently practice can still be considered atypical [51,52]. The Saami of northern Sweden [53] do provide another example where local plant species traditionally played a relatively minor part in healing practices compared to animal, mineral, and magical cures. Unfortunately, older literature on Naukan ethnobotany is scant [10], particularly for medicinal uses. So, we take another approach here to support elders' reports of borrowings. Following other researchers [32][33][34], who have used comparative ethnography to help triangulate memory ethnography, we examine Soviet era popular literature on the medicinal and nutritional qualities of plants [35][36][37][38]. The idea is to test whether newcomers arriving in Chukotka from other parts of Russia, including professionals such as teachers, doctors, and health aids, could have brought new information on medicinal uses of local plants as Naukan elders described. We have italicized those uses in Table 3 where this comparative evidence (for the same or closely related species) supports the alleged borrowing.  Current and past Naukan medicinal plant use diverges in some notable ways from that of neighboring societies on the Alaskan side of the Bering Strait. Although the floras of both regions are very similar [54], the most salient medicinal species are different. For example, Artemisia tilesii Ledeb. and Rhododendron tomentosum Harmaja are the two most important and commonly mentioned medicinal plants among the Central Alaskan Yup'ik [41,43] and Iñupiat [47,55] of western Alaska. Although both species were cited by Naukan elders as medicinal, their use values of 0.28 (for Artemisia tilesii Ledeb.) and 0.31 (for Rhododendron tomentosum Harmaja) indicate that their importance in this pharmacopeia is minor. Also, Naukan elders claim that they did not use either species before Russian influence, while there are no similar claims of borrowing on the Alaskan side [41,47]. By the same token, species of greater medicinal importance for the Naukan, such as Angelica gmelinii (DC.) Pimenov and Rubus chamaemorus L., are principally used for food among the Iñupiat [47] and Central Alaskan Yup'ik [41].
Naukan spiritual plant uses appear in Table 4. In current times, there is only really one species of any great spiritual importance, Angelica gmelinii (DC.) Pimenov. Its root is burned for a variety of ritual and medicinal purposes. Oral histories suggest this same plant was the most important spiritual species in the past as well, although there were others that very few elders remember now. The Central Alaskan Yup'ik people, in contrast, burn the strongly aromatic species Rhododendron tomentosum Harmaja for spiritual cleansing [41]. However, Oswalt [56] reported that Yup'ik people in the middle Kuskokwim region of Alaska remembered formerly burning the tops of dried Angelica gmelinii (DC.) Pimenov for smudging. More recently, Jernigan [41] reports a similar cultural memory from the village of Chevak, on the Bering Sea coast, of previous use of this same species for ceremonial cleansing during the Nakaciuq (Bladder festival).
It is worth noting that our findings about one particular species of spiritual significance to the Naukan, Lagotis glauca Gaertn., conflict with some earlier published accounts. Both Menovshchikov [10] and Ainana and Zagrebin [1] wrote that this species is called ngerngaq in Naukan and is stored with Saxifraga nelsoniana D. Don leaves in seal oil to eat during the winter. However, all participants in this study assigned the name ngerngaq and its edible use to Rumex arcticus Trautv. No one we interviewed considered Lagotis glauca Gaertn. to be a food, and most did not know a name or significance. A few elders independently gave the name qungum neqenllaa-"dead man's bistort." The name stems from a resemblance to the local edible species Persicaria bistorta (L.) Samp. and comes from the fact that this plant was considered to be food for the dead. The discrepancy with earlier published literature can be explained by noting that Menovshchikov [10] and Ainana and Zagrebin [1] did most of their fieldwork with speakers of the related Chaplinskiy Yupik language, rather than in the Naukan area.

Conclusion
Testimony of Naukan elders indicates a decrease in the number of species harvested for food over the last 60 years. However, there has been an increase in the ways that edible plants are prepared due to the influence of Russian and Chukchi neighbors. Knowledge of spiritual species has also shown significant decline.
The most surprising result of this research is the direction of change in medicinal plant use. The Naukan present an interesting case where acculturative forces appear to Naukan participants often said that their original concept of medicine emphasized prevention. For example, the leaves of willows (Salix pulchra Cham.) and willow herb (Epilobium latifolium L.) aid the digestive system and help prevent stomach upset when they are eaten as part of a meal. This traditional emphasis on staying healthy reflects findings by researchers working in some other parts of the arctic as well.
For instance, Hakkarainen [57] has observed that the reindeer-herding Chukchi have tended to use plants for maintaining health rather than curing sickness. Black et al. [58] report that preventative medicine is the most important category for the Iñuit of Qikiqtaaluk, Nunavut. Naukan elders also emphasized that, when people became sick in the old days, they often assigned a spiritual cause. So that meant the cure also had to be spiritual rather than physical in nature. Bogoraz's [7,8] classic ethnography with the neighboring Chukchi also mentions a dearth of medicinal plant usage, stating that cures were largely spiritual. In contrast to many other parts of the world [59,60], Naukan elders reported that they did not rely on psychoactive plants to achieve altered states of consciousness. According to native scholar Tein et al. [18], Naukan shamans established relationships with helper spirits in visions or dreams. The spirits, in turn, would teach the healers special songs that would allow the latter to make contact in the future. The shamans also healed the sick with the help of these spirits and with symbolic acts like changing the name of a sick child or blowing an illness toward the door of a dwelling. So, it is clear that increased integration with ethnic Russians after moving from Naukan led to the adoption not only of new plant uses, but also of an entirely different, more naturalistic way of viewing illness and healing.
The authors are currently carrying out research on the ethnobotanical traditions of the neighboring Chukchi and the Central Alaskan Yup'ik to expand the discussion of the plant traditions of the Bering Strait region. Future work could also expand the region of study to other adjacent locations such as Little Diomede and the Seward Peninsula which both had a high degree of historical contact [16] with the Naukan people.
