Why the ongoing occupation of Ukraine matters to ethnobiology.

Ethnobiology and ethnomedicine investigate the continuously changing complex and inextricable relations among culture, nature, and health. Since the emergence of modern ethnobiology a few decades ago, its essence and mission have been the study of biocultural diversities and the centers of its inquiries have been and are local communities and their co-evolutionary interrelationships between natural environments and social systems. At the core of ethnobiologists' work there are not only conceptualizations of and reflections on others' views about nature and the universe, but also a robust commitment to advocacy in defense of these assemblages of local ecological knowledge, practices, and beliefs (LEK). Homogenization processes and therefore erosion of LEK have occurred throughout history in different ways: from colonialism to industrialization, and from financialization to globalization; however, we cannot forget the role played by centripetal states and even dictatorships in this process, nor the associated political ideology of nationalism, which has often elicited and justified policies aimed at standardizing diversities within state borders. Our research groups have been working since eight years together with local communities in Ukrainian rural areas and documented a remarkable erosion of LEK during the Soviet times, yet an extraordinary surviving biocultural diversity occurs; the ongoing military occupation of Ukraine could further threaten this heritage. While citizens' attention now should be on effectively supporting those who are experiencing hardships during this traumatic time, ethnobiologists will be called hopefully soon to directly participate in rebuilding the biocultural "cobwebs" damaged by the military operations.

Knowledge transmission patterns at the border: ethnobotany of Hutsuls living in the Carpathian Mountains of Bukovina (SW Ukraine and NE Romania).

BACKGROUND: Cross-border research is a novel and important tool for detecting variability of ecological knowledge. This is especially evident in regions recently divided and annexed to different political regimes. Therefore, we conducted a study among Hutsuls, a cultural and linguistic minority group living in Northern and Southern Bukovina (Ukraine and Romania, respectively). Indeed, in the 1940s, a border was created: Northern Bukovina was annexed by the USSR while Southern Bukovina remained part of the Kingdom of Romania. In this research, we aim to document uses of plants for food and medicinal preparations, discussing the different dynamics of Local Ecological Knowledge (LEK) transmission among Hutsuls living in Ukraine and Romania. METHODS: Field research was conducted using convenience and snowball sampling techniques to recruit 31 Hutsuls in Ukraine and 30 in Romania for participation in semi-structured interviews regarding the use of plants for medicinal and food preparation purposes and the sources of such knowledge. RESULTS: The interviews revealed that, despite a common cultural and linguistic background, ethnobotanical knowledge transmission occurs in different ways on each side of the border. Family is a primary source of ethnobotanical knowledge transmission on both sides of the border; however, in Romania, knowledge from other sources is very limited, whereas in Ukraine interviewees reported several other sources including books, magazines, newspapers, the Internet and television. This is especially evident when analysing the wild plants used for medicinal purposes as we found 53 taxa that were common to both, 47 used only in Ukraine and 11 used only in Romania. While Romanian Hutsuls used almost exclusively locally available plants, Ukrainian Hutsuls often reported novel plants such as Aloe vera, Aronia melanocarpa and Elaeagnus rhamnoides. Knowledge related to these plants was transferred by sources of knowledge other than oral transmission among members of the same family. Therefore, this may imply hybridization of the local body of knowledge with foreign elements originating in the Soviet context which has enriched the corpus of ethnobotanical knowledge held by Ukrainian Hutsuls. CONCLUSIONS: While ethnobotanical knowledge among Romanian Hutsuls is mainly traditional and vertically transmitted, among Ukrainian Hutsuls there is a considerable proportion of LEK that is transmitted from other (written and visual) sources of knowledge. This cross-border research reveals that despite a common cultural background, socio-political scenarios have impacted Hutsul ethnobotanical knowledge and its transmission patterns.

Gaining momentum: Popularization of Epilobium angustifolium as food and recreational tea on the Eastern edge of Europe.

The local use of wild food plants represents a reservoir for the biocultural diversity of human diet and is therefore being extensively studied; yet the effects of the introduction of novel uses into specific biocultural conditions have been little researched. Rosebay willowherb Epilobium angustifolium L. has been intensively promoted in Europe since the mid-18th century. The expert recommendations did not provide any links to local uses thus raising the question of the legitimacy and diffusion of its food use in modern times. To understand if and to what extent those recommendations have influenced local uses, we compared them with the results of our ethnobotanical field study and the ethnographic literature in Russia, Finland, Estonia, Latvia, Lithuania, Belarus and Ukraine. Of the 599 people interviewed, nine used E. angustifolium as a food and 59 as a recreational tea. Thirty-four of those who claimed to use E. angustifolium lived in two regions of Russia. The majority of the recorded tea uses were of recent origin, following a popular trend. Few food uses of E. angustifolium were recorded in Finland, where a trend towards culinary experimentation coincides with a general trend toward the consumption of healthy wild food; yet these uses are difficult to maintain due to the problems in recognizing the plant during its early stages of growth. The popularization of E. angustifolium as a food had more effect in times of hardship, when it was seen as a means of survival and its promotion was advocated. The translation error repeatedly appeared in botanical and later popular literature, whose authors did not clearly differentiate at that time between local uses and suggestions.

Borders as Crossroads: The Diverging Routes of Herbal Knowledge of Romanians Living on the Romanian and Ukrainian Sides of Bukovina.

Cross-border and cross-cultural ethnomedicine are novel ways to address the evolution of local ecological knowledge. As is widely acknowledged, ethnomedicinal knowledge is not static, but evolves according to several factors, including changes in ecological availability and socioeconomic conditions, and yet the effect of the political context on medicinal knowledge remains largely underexplored. Bukovina, a small region of Eastern Europe that has been divided by a border since the 1940s and is currently part of both Romania and Ukraine, represents a unique case study in which to address the impact of political contexts on ethnomedicinal knowledge. The aim of this study was to compare plant-based medicinal uses among Romanians living on the two sides of the Romanian-Ukrainian border. In addition, we performed cross-cultural and cross-border analysis with published data on the ethnomedicine of the neighboring ethnolinguistic group of Hutsuls. We conducted 59 semistructured interviews with conveniently selected Romanians living in both Romanian and Ukrainian Bukovina. We elicited preparations for treating different ailments and disorders by naming each part of the body. We also asked about the sources of this medicinal knowledge. We documented the medicinal use of 108 plant taxa belonging to 45 families. Fifty-four taxa were common to both Romanian communities; 20 were only found among Romanians living in Romania and 34 only among Romanians living in Ukraine. However, the number of recorded uses was higher among Romanians living in Romania, revealing that they make consistent use of local medicinal plants, and Romanians living in Ukrainian Bukovina use more taxa but less consistently. Comparison with the data published in our study on neighboring Hutsuls shows that medicinal knowledge is more homogeneous among Hutsuls and Romanians living in Ukraine, yet many similar uses were found among Romanian communities across the border. We argue that the 50 years during which Ukrainian Bukovina was part of the USSR resulted in the integration of standard pan-Soviet elements as evidenced by several plant uses common among the groups living in Ukraine yet not among Hutsuls and Romanians living in Romania.

Inventing a herbal tradition: The complex roots of the current popularity of Epilobium angustifolium in Eastern Europe.

ETHNOPHARMACOLOGICAL RELEVANCE: Currently various scientific and popular sources provide a wide spectrum of ethnopharmacological information on many plants, yet the sources of that information, as well as the information itself, are often not clear, potentially resulting in the erroneous use of plants among lay people or even in official medicine. Our field studies in seven countries on the Eastern edge of Europe have revealed an unusual increase in the medicinal use of Epilobium angustifolium L., especially in Estonia, where the majority of uses were specifically related to "men's problems". THE AIM OF THE CURRENT WORK IS: to understand the recent and sudden increase in the interest in the use of E. angustifolium in Estonia; to evaluate the extent of documented traditional use of E. angustifolium among sources of knowledge considered traditional; to track different sources describing (or attributed as describing) the benefits of E. angustifolium; and to detect direct and indirect influences of the written sources on the currently documented local uses of E. angustifolium on the Eastern edge of Europe. MATERIALS AND METHODS: In this study we used a variety of methods: semi-structured interviews with 599 people in 7 countries, historical data analysis and historical ethnopharmacological source analysis. We researched historical and archival sources, and academic and popular literature published on the medicinal use of E. angustifolium in the regions of our field sites as well as internationally, paying close attention to the literature that might have directly or indirectly contributed to the popularity of E. angustifolium at different times in history. RESULTS: Our results show that the sudden and recent popularity in the medical use of E. angustifolium in Estonia has been caused by local popular authors with academic medical backgrounds, relying simultaneously on "western" and Russian sources. While Russian sources have propagated (partially unpublished) results from the 1930s, "western" sources are scientific insights derived from the popularization of other Epilobium species by Austrian herbalist Maria Treben. The information Treben disseminated could have been originated from a previous peak in popularity of E. angustifolium in USA in the second half of the 19th century, caused in turn by misinterpretation of ancient herbals. The traditional uses of E. angustifolium were related to wounds and skin diseases, fever, pain (headache, sore throat, childbirth), and abdominal-related problems (constipation, stomach ache) and intestinal bleeding. Few more uses were based on the similarity principle. The main theme, however, is the fragmentation of use and its lack of consistency apart from wounds and skin diseases. CONCLUSIONS: Historical ethnobotanical investigations could help to avoid creating repeating waves of popularity of plants that have already been tried for certain diseases and later abandoned as not fully effective. There is, of course, a chance that E. angustifolium could also finally be proven to be clinically safe and cost-effective for treating benign prostatic hyperplasia, but this has not yet happened despite recent intensive research. Documented traditional use would suggest investigating the dermatological, intestinal anti-hemorrhagic and pain inhibiting properties of this plant, if any.

From economic survival to recreation: contemporary uses of wild food and medicine in rural Sweden, Ukraine and NW Russia.

BACKGROUND: There are many ethnobotanical studies on the use of wild plants and mushrooms for food and medicinal treatment in Europe. However, there is a lack of comparative ethnobotanical research on the role of non-wood forest products (NWFPs) as wild food and medicine in local livelihoods in countries with different socio-economic conditions. The aim of this study was to compare the present use of wild food and medicine in three places representing different stages of socio-economic development in Europe. Specifically we explore which plant and fungi species people use for food and medicine in three selected rural regions of Sweden, Ukraine and the Russian Federation. METHODS: We studied the current use of NWFPs for food and medicine in three rural areas that represent a gradient in economic development (as indicated by the World Bank), i.e., Småland high plain (south Sweden), Roztochya (western Ukraine), and Kortkeros (Komi Republic in North West Russia). All areas were characterised by (a) predominating rural residency, (b) high forest coverage, and (c) free access to NWFPs. A total of 205 in-depth semi-structured interviews were conducted with local residents in the three study areas. The collected NWFPs data included (1) the species that are used; (2) the amount harvested, (3) uses and practices (4) changes over time, (5) sources of knowledge regarding the use of NWFPs as wild food and medicine and (6) traditional recipes. RESULTS: In Sweden 11 species of wild plant and fungi species were used as food, and no plant species were used for medicinal purposes. In Ukraine the present use of NWFPs included 26 wild foods and 60 medicinal species, while in Russia 36 food and 44 medicinal species were reported. CONCLUSIONS: In the economically less developed rural areas of Ukraine and Russia, the use of NWFPs continues to be an important part of livelihoods, both as a source of income and for domestic use as food and medicine. In Sweden the collection of wild food has become mainly a recreational activity and the use of medicinal plants is no longer prevalent among our respondents. This leads us to suggest that the consumption of wild food and medicine is influenced by the socio-economic situation in a country.
