[PMID: 39367458 PMCID: PMC11451187 DOI: 10.1186/s13002-024-00732-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Accepted: 09/13/2024] [Indexed: 10/06/2024]
Abstract
In mountainous areas, wild edible plants are an important part of the local diet. Climate change and anthropogenic activities have profound effects on wild edible plants in these areas. Ethnobotanical studies are important for understanding the use patterns and harvest impacts on these plants. In this regard, the Shahrood region, with its diverse historical/ethnic background, is an appropriate starting point to investigate exploitation patterns and impacts of harvest of wild edible plants. During 2021-2022, ethnobotanical surveys were conducted in 12 villages in the region using semi-structured interviews and participatory observations. Data collection included assessing wild edible plant species diversity, their habitats, collection time and quantities, plant parts used and methods of consumption and preparation. The data were analyzed using use report indicators, relative frequency of citations, and use value (UV). A total of 1086 use reports were documented from a total of 44 interviews. A total of 67 wild species (66 plants and 1 fungus) belonging to 54 genera and 24 families were used as edible in the study area. Rosaceae (9 species), Apiaceae (8), Lamiaceae (8), Asteraceae (7), and Amaryllidaceae (5) were the families with the most reported species. Allium (5 species) was the most diverse genus in terms of species diversity. Herbs were the most commonly used life form (79.1%), followed by shrubs (13.4%) and trees (6%). The most consumed plant parts were young leaves (25%) and young aerial parts (21.4%). There were 13 use categories identified. The majority of edible plants were collected in April-May, mainly from areas nearby villages (37.7%) and rangelands (33.7%). The most important edible plants in the study area were Allium iranicum (Wendelbo) Wendelbo (UV = 1.7), Mentha longifolia (L.) Huds. (1.5), Allium umbilicatum Boiss. (1.47), Tragopogon graminifolius DC. (1.38), Lepidium draba L. (1.27), Urtica dioica L. (1.18), Falcaria vulgaris Bernh. (1.13), Malva neglecta Wallr. (1.11) and Eremurus sp. (1.09). Our results showed diverse and valuable knowledge for wild edible plants in this region, which should be considered in the conservation and management plans in the region.

Wang J, Ding X, Guo CA, Zhang X, Feng H, Yang H, Wang Y. An ethnobotanical study of wild edible plants used by the Tibetan in the Rongjia River Valley, Tibet, China. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2023; 19:49. [PMID: 37891585 PMCID: PMC10612173 DOI: 10.1186/s13002-023-00621-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 10/20/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND Wild edible plants (WEPs) play a crucial role in communities with limited communication with the outside world, where unstable factors, such as poor food supply and insufficient access to timely nutritional supplementation, are common, as in the Himalayan region. To document the traditional knowledge of WEPs and explore their significance for communities with minimal global economic exchange, an ethnobotanical study was conducted in the town of Rongjia, which lies in a narrow valley near Mount Everest, Tibet, China. METHODS This ethnobotanical study was conducted in three villages in the Rongjia River Valley between August 2021 and June 2023. Semi-structured interviews and participatory observations were used to collect information on WEPs. The fieldwork was performed with the assistance of local guides. Voucher specimens were collected from each documented plant species for taxonomic identification. We used the use report (UR) and relative frequency of citations (RFC) to evaluate the comprehensive utilization value of WEPs. RESULTS We interviewed 161 informants who provided us with 2499 use reports. We collected 50 WEPs belonging to 28 families and 42 genera used by the Tibetan people in the Rongjia River Valley. WEPs are used in vegetables, fruits, seasonings, healthcare foods, substitute grains, and beverages. Wild vegetables were the most commonly used, followed by wild fruits. Leaves were the most commonly consumed part of the plant. The three most important WEPs ordered by RFC values were Rosa sericea var. glandulosa Osmaston (RFC = 0.76), Zanthoxylum bungeanum Maxim. (RFC = 0.75), and Urtica hyperborea Jacquem. ex Wedd. (RFC = 0.71). Other than that, we also document some of WEPs used in the past. Arisaema erubescens Schott, Pinellia ternata (Thunb.) Makino, and Satyrium nepalense var. ciliatum (Lindl.) Hook. f. used to serve as important substitute grains, are no longer in use, however, they remain vivid in the memories of older people. CONCLUSIONS WEPs included wild vegetables, fruits, seasonings, healthcare food, and substitute grains for Tibetan people in the Rongjia River Valley. Some WEPs have become important cultural symbols for older people, which can help in understanding the relationship between plants and local people in the past. In addition, WEPs can increase the resilience of local people living in remote areas when facing sudden destabilizing events in future. This is the significance of WEPs for communities with minimal global economic exchange. Therefore, we suggest that future studies focus more on WEPs in communities with limited communication with the world to improve their resilience.

Guo CA, Ding X, Hu H, Zhang Y, Bianba C, Bian B, Wang Y. A comparison of traditional plant knowledge between Daman people and Tibetans in Gyirong River Valley, Tibet, China. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2023; 19:14. [PMID: 37147662 PMCID: PMC10163752 DOI: 10.1186/s13002-023-00583-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Accepted: 04/13/2023] [Indexed: 05/07/2023]
Abstract
BACKGROUND By comparing the differences in plant use between various cultures or regions, we can gain a better understanding of traditional knowledge of plant use among different groups, which may lead to a more objective understanding. Even though the Tibetan and Daman people live in the same ecosystem in Gyirong town, China, their cultural backgrounds and livelihoods differ. Therefore, the objective of this study is to document the traditional knowledge of plant use among the Daman people and compare it with the local Tibetan knowledge of plant use. By doing so, we aim to explore the relationship between plant selection and use and the cultural backgrounds of different groups. METHODS During fieldwork, ethnobotanical data were collected using various methods including free listings, key informant interviews, and semi-structured interviews. To quantify the importance of plant species in the Daman people's culture, the culture importance index, informant consensus factor index, and The Index of Agreement on Species consensus (IASc) were used. In addition, we cited previous ethnobotanical survey data from the Tibetan in Gyirong. To more comprehensively compare the differences in plant use between the Daman and Tibetan, this study constructed a knowledge network to compare the knowledge differences between the two groups. RESULTS In this study, traditional knowledge was collected from 32 Daman informants, resulting in a total of 68 species belonging to 39 families mentioned by Daman people and 111 species mentioned by Tibetans. Of these, 58 plants were used by both populations. The plants were classified into 3 categories and 28 subcategories, with 22 identical classes in both groups. The majority of use categories showed a high degree of sharing in both groups, and the Tibetan people had more plant use categories than the Daman people. Five plants with IASc value > 0.5 were identified in both groups: Rhododendron anthopogon D. Don, Artemisia japonica Thunb., Juniperus indica Bertol., Gastrodia elata Blume, and Rheum australe D. Don. The analysis of the knowledge network revealed a 66% overlap between the knowledge of the Daman and the knowledge of the Tibetans. Additionally, the plant knowledge of Tibetan people was found to be richer and more complex than that of the Daman people. However, the Daman people possess 30 unique knowledge items. CONCLUSIONS From the perspective of plant use, the history of the Daman people's discrete migration on the border between China and Nepal allows them to retain their own knowledge of plant use. The status quo of joining Chinese nationality and settling in Gyirong town allows them to gradually integrate into the local Tibetan society. In summary, despite living in the same ecosystem and biodiversity background, the plant utilization of the Daman people and Tibetans still shows significant differences, which are due to their different cultural backgrounds and social status.

The traditional use of wild edible plants in pastoral and agro-pastoral communities of Mieso District, eastern Ethiopia. Trop Med Health 2023; 51:10. [PMID: 36814353 PMCID: PMC9948460 DOI: 10.1186/s41182-023-00505-z] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 02/18/2023] [Indexed: 02/24/2023] Open
Abstract
BACKGROUND The populations in Ethiopia have developed their indigenous knowledge to use, manage and conserve wild edible plants (WEPs). In the eastern part of Ethiopia, wild edible plants are used as a means of survival during times of food shortage and as dietary supplements. Documenting the traditional and cultural use of wild food plants is a vital step in obtaining baseline data for investigating nutritional values and possible side effects, preserving indigenous knowledge, and ultimately interesting in wild edible plant conservation. However, their significance, management and utilization have not been documented in Mieso District. Therefore, this study aimed to provide documentation of wild edible plant use associated with ethnobotanical knowledge in Mieso District, eastern Ethiopia. METHODS An ethnobotanical study of wild edible plant species was conducted from March 2021 to May 2022. A total of 120 (72 males and 48 females) informants were selected using the snowball method. Data collection methods, including semistructured interviews, direct observation and field walks were used. Data were analysed using descriptive statistics, including independent sample t test and analysis of variance (ANOVA). We calculated use values (UVs) to analyse the relative cultural importance of each plant species. RESULTS A total of 41 wild edible plant species belonging to 33 genera in 21 families were documented to be used as food sources both during times of food shortage and as dietary supplements. Family Malvaceae was best-represented with 6 species, followed by Fabaceae and Rhamnaceae (4 species each). The dominant growth form (habit) was shrubs (30 species), followed by trees (11 species). The most widely used plant parts were fruits (covering 39 species, 95%). The largest number (23 species) was collected from forest habitats only, followed by both village and forest habitats (8 species). The majority of wild edible plants (28 species or 68%) were consumed only during famine or in the time of food shortage followed by supplementing staple foods (9 species or 22%). Wild edible plants in Mieso are used for multiple other uses, including for fodder, fuel, medicine, construction, cosmetics and bee keeping. Twenty-three species were mentioned for fodder use, followed by fuel purpose (21 species) and medicinal value (13 species). The species that had the highest use values were Flacourtia indica (Burm.f.) Merr. (1.4), Carissa spinarum L. (1.1), Ziziphus spina-christi (L.) Desf. (0.6), Grewia villosa Willd. (0.5), Cordia monoica Roxb. (0.3) and Opuntia ficus-indica (L.) Mill. (L.) (0.2). Most WEPs were collected from March to May (Badheysa) (33 species). The highest mentioned wild edible plant sold in the market was F. indica (Burm.f.) Merr. mentioned by 20 informants, followed by Z. spina-christi (L.) Desf. (14). CONCLUSION The people in Mieso use wild plants as supplementary food to cultivated crops, during famine, and many could be utilized for day-to-day human consumption. Some plants in the district provide cash income for local people. However, deforestation (54%), drought (22%) and agricultural expansion (12%) were the highest threats to wild plants in Mieso District. Hence, on-site and off-site conservation would help protect wild plant resources in Mieso, eastern Ethiopia.

Ultrasonic Treatment Enhances the Antioxidant and Immune-Stimulatory Properties of the Polysaccharide from Sinopodophyllum hexandrum Fruit. Foods 2023; 12:foods12050910. [PMID: 36900428 PMCID: PMC10001073 DOI: 10.3390/foods12050910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 01/31/2023] [Accepted: 02/02/2023] [Indexed: 02/24/2023] Open
Abstract
We aimed to assess the potential of ultrasonic treatment on the processing of polysaccharides as functional foods or food additives. The polysaccharide from Sinopodophyllum hexandrum fruit (SHP, 52.46 kDa, 1.91 nm) was isolated and purified. SHP was treated with various levels of ultrasound (250 W and 500 W), resulting in the formation of two polysaccharides, SHP1 (29.37 kD, 1.40 nm) and SHP2 (36.91 kDa, 0.987 nm). Ultrasonic treatment was found to reduce the surface roughness and molecular weight of the polysaccharides, leading to thinning and fracturing. The effect of ultrasonic treatment on polysaccharide activity was evaluated in vitro and in vivo. In vivo experiments showed that ultrasonic treatment improved the organ index. Simultaneously, it enhanced the activity of superoxide dismutase, total antioxidant capacity, and decreased the content of malondialdehyde in the liver. In vitro experiments demonstrated that ultrasonic treatment also promoted proliferation, nitric oxide secretion, phagocytic efficiency, costimulatory factors (CD80+, CD86+) expression, and cytokine(IL-6, IL-1β) production of RAW264.7 macrophages.

Conservation of Biocultural Diversity in the Huasteca Potosina Region, Mexico. DIVERSITY 2022. [DOI: 10.3390/d14100841] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/05/2022]
Abstract
The Huasteca Potosina region has a relevant landscape heritage of biocultural diversity, due to high biological diversity and the presence of the Teenek (Huastec Mayan), Nahua, and Xi’iuy (Pame) ethnic groups. The object of this study is to analyze, among the different cultural groups of the region, how the performances of the relevant Socioecological Systems (SESs) influence the conservation of biocultural diversity. Quantitative approaches are used to determine the expected trends of indices (Informant Consensus Factor, ICF; Cultural Importance Index, CII; Shannon–Wiener Biodiversity Index, SWI) commonly used in the ethnobotanical field. Data of the main domestic forest species used by the groups mentioned above were collected in 2021. We analyzed the SES profile for each of the ethnic groups and a mestizo group, as well as their relationship with the biome they mainly inhabit and the domestic functions fulfilled by the ethnobotanical species. As a result, we found that the low deciduous forest and the sub-evergreen tropical forest biomes, which co-evolved mainly with the Nahua and the Teenek SESs, present higher diversity and effective use of species so that offer better chances for conserving the landscape heritage of biocultural diversity. Otherwise, the results also show the critical nature regarding the biomes inhabited by the Pame and the mestizo’s SESs.

Transcriptome and Metabolome Analyses of Codonopsis convolvulacea Kurz Tuber, Stem, and Leaf Reveal the Presence of Important Metabolites and Key Pathways Controlling Their Biosynthesis. Front Genet 2022; 13:884224.

Abstract
Codonopsisconvolvulacea Kurz. var. vinciflora (Kom.) L.T. Shen is a member of Campanulaceae, which is used in traditional Chinese medicine. However, apart from a few Codonopsis species, no detailed knowledge is available on the metabolite composition and respective transcriptome signatures. We performed a combined transcriptome and metabolome analysis of the tuber, stem, and leaf of C. convolvulacea and found 1,144 metabolites and 231,840 unigenes in three experimental groups. The analysis revealed considerable variations in the three tissues. Tubers were rich in amino acids and derivatives, flavonoids, and organic acids, whereas the stems and leaves were rich in alkaloids and flavonoids, respectively. Transcriptome sequencing revealed candidate genes being involved in flavonoid, tryptophan, and alkaloid biosyntheses. In particular, we indicated that the variation in the isoflavone content is linked to the expressions of CHI, CYP73A, C3′H, F3H, CYP75B1, anthocyanidin synthase, and FLS. In a similar way, the levels of indole, L-tyrosine, and tryptamine were also consistent with the expressions of TDC/DDCs in the respective tissues. In addition, the expression levels of ASP5, ARO8, GOT, and AOC3 indicated that L-tryptophan is being converted to downstream metabolites. Overall, our datasets present a useful resource for future research on the uses of this medicinal plant and put forward many research questions.

Abstract
INTRODUCTION Plant resources gathered from the wild are important sources of livelihood needs, especially for low-income populations living in remote areas, who rely on these plants for food, fuelwood, medicine and building materials. Yadong County is a valley at the border between the China, India and Bhutan in southern Tibet. Yadong is rich in biodiversity and culture, but ethnobotanical knowledge has not been systematically studied. This study aimed to document the ethnobotanical knowledge of Tibetans in Yadong County. METHODS Ethnobotanical data were documented through free listings, key informant interviews, and semi-structured interviews during fieldwork. The culture importance index (CI) and informant consensus factor index (FIC) were used as the quantitative indices. RESULTS In total, 163 informants (46 women and 117 men). A total of 3,031 use reports and 121 plant species belonging to 52 families and 91 genera were included. These use reports were then classified into 20 categories belonging to 9 major categories. The utilisation category that containing the most plant species was food, followed by economic, medicine, animal feed, social uses, other uses, environmental uses, materials and fuels. Among the economic plants, 32 medicinal plants are traditionally used in the local region. Plants with high CI included Fritillaria cirrhosa, Neopicrorhiza scrophulariiflora, Betula utilis, Rheum nobile, and Urtica hyperborean. CONCLUSION This research demonstrates the diversity of the types and functions of Yadong Tibetan traditional plant knowledge. Knowledge of edible and medicinal plants in this area is prominent, reflecting the ability to cope with the lack of fruits and vegetables and basic family medical care. There were exchanges between the traditional plant culture in the study area and its surroundings. With socioeconomic development, the commercial value of medicinal plants has increased, and locals are also seeking ways to adoptsustainable development to cope with the excessive consumption of plant resources.

Sharma R, Sharma YP, Hashmi SAJ, Kumar S, Manhas RK. Ethnomycological study of wild edible and medicinal mushrooms in district Jammu, J&K (UT), India. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2022; 18:23. [PMID: 35331275 PMCID: PMC8953059 DOI: 10.1186/s13002-022-00521-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Accepted: 03/07/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Union Territory of Jammu and Kashmir (J&K) has a rich tradition of usage of wild edible mushrooms (WEMs) for culinary and medicinal purposes. But very few studies, restricted to some regions of the Union Territory, have been conducted to enlist the WEM. District Jammu has never been explored for WEM. Moreover, the quantification of the traditional knowledge of WEM has not been carried out as yet in J&K. Therefore, the present study was conducted in the Jammu district with the aims of enlisting the WEM and its usage, finding the most used WEM, and enumerating the consensus of usage for a species and associated knowledge. METHODS A total of 192 informants between the age of 25 and 87 years were interviewed. The collected information was organized and arranged based on use reports for quantitative analysis. The cultural importance index (CI) and factor informant consensus (Fic) were calculated to estimate the cultural importance and to test homogeneity of information and knowledge sharing about WEM, respectively. Analysis of variance was used to evaluate the significance of differences in the usage of WEM among different informant categories. RESULTS Results of the present study show that the locals were having knowledge of fourteen fleshy fungi that are mainly utilized for culinary purposes. They also stated various medicinal values of some of these fungi. Agaricaceae and Lyophyllaceae were the most used families, and Termitomyces (5 species) was the most represented genus. Based on CI values, Termitomyces sp. (CI 0.57) was the most important and diversely used species. Termitomyces heimii, Termitomyces clypeatus, and Termitomyces striatus var. annulatus were the other culturally important and frequently consumed species by the locals. More than 78.6% of these WEM were new records as culinary and medicinal for J&K (UT). The values of factor informant consensus (Fic) varied between 0.98 (culinary) and 0.76 (skin diseases). Females, elders, and informants who have not attended schools were having significantly (P < 0.05) higher information regarding WEM. CONCLUSION The inhabitants of district Jammu had good knowledge of WEM, but no documentation, lying of most of the information with elders and uneducated people, and destruction of forests and other natural habitats of WEM pose a serious threat of losing this valuable information in near future. An ardent need is to educate locals regarding regionally available WEM. Further studies are recommended for developing protocols of cultivation of these WEM so that their future availability is ascertained along with creating income resources for the local population.

JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2022; 18:19. [PMID: 35303920 PMCID: PMC8933993 DOI: 10.1186/s13002-022-00519-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Accepted: 03/01/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND The local Dong people in Qiandongnan Prefecture, Guizhou Province, China, with rich biocultural diversity, have developed the traditional rice-duckweed-fish-duck agroecosystem (RDFDA) to support biodiversity conservation and to meet food and cultural needs. However, there is still not much research on traditional ecological knowledge (TEK) in this area. In particular, there is a lack of traditional knowledge of edible plants used by the Dong people as flavoring to grill fish (Cyprinus carpio) collected from RDFDA, which is extremely valuable in their traditional culture. The study focused on documenting plant species used in grilling fish and analyzing the status of its TEK. METHODS Twenty-one sampling points of three Dong minority villages in Qiandongnan were selected for the research. The local TEK associated with plant resources for fish-grilling was recorded through free listing and semi-structured interviews. Fidelity level (FL) and ethnoecological importance value (EIV) indicators were designed to determine the socioeconomic influence of TEK. The non-metric multidimensional scaling (NMDS) method was used to evaluate the differentiation of edible plant species distribution in dissimilar accessibility types. RESULTS A total of 430 people were interviewed about grilled fish, of whom 75% were men and 85% were farmers. Thirty-four edible plants were documented for fish-grilling in three Dong villages. They belong to 16 plant families, such as Apiaceae, and Asteraceae. The life forms included herbaceous (76%), shrubs (18%) and trees (6%). Leaves are the most commonly used part of for grilling fish, followed by aerial parts, and whole plants. Among these edible plants, Allium hookeri, A. macrostemon and Houttuynia cordata with the highest fidelity level (100%) were cited as edible plants for grilling fish by all informants. The NMDS showed different accessibility types of collection sites, with different importance values. Paddy rice field edge (2.03) has the highest value, followed by forest-farming ecotone (1.74), streamsides (1.71) and woodland (0.48). CONCLUSION The purpose of this study was to investigate the traditional knowledge of edible plant materials used by the Dong people for grilling fish. The results demonstrate the strong connection between local people, the bio-environment and agroecosystem services. The survey and comparative analysis revealed that plant species with high FL values may be potential sources of natural flavors.

Cheng Z, Lu X, Lin F, Naeem A, Long C. Ethnobotanical study on wild edible plants used by Dulong people in northwestern Yunnan, China. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2022; 18:3. [PMID: 35062974 PMCID: PMC8781162 DOI: 10.1186/s13002-022-00501-3] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 01/07/2022] [Indexed: 05/23/2023]
Abstract
BACKGROUND Dulong (Drung people) are one of the ethnic minorities of China, consisting of a small population living in remote and mountainous regions with limited facilities. Over the years, the Dulong have maintained their livelihood by collecting wild medicinal and edible plants. Therefore, through their experience and understanding, they had accumulated sufficient traditional knowledge about local plant resources. Since ancient times, wild edible plants have been essential to the food security of the Dulong people. However, there is almost no comprehensive report available on WEPs consumed by the Dulong people. The objectives of this study were to: (1) make a systematic study of WEPs used by Dulong people, (2) record traditional knowledge related to WEPs, (3) analyze multiple uses of WEPs, and (4) evaluate species with significant cultural significance to Dulong people. METHODS Ethnobotanical survey including free listing, semi-structured interviews, key informant interviews and participatory observations was conducted in Dulongjiang Township, Gongshan County, Yunnan Province, Southwest China. A total of 127 informants were selected using the snowball method and information about WEPs, including vernacular name, food categories, parts used, mode of consumption, collection season, and other local uses were collected. The RFC and CFSI were calculated to identify the most culturally significant WEPs. One-way analysis of variance was performed to evaluate whether the four reference variables (gender, age, occupation, and education) significantly influenced the number of plant species mentioned by the respondents. RESULTS AND DISCUSSION A total of 148 species of WEPs consumed by the Dulong people belonging to 58 families were collected, including wild vegetables (71), wild fruits (52), staple food substitutes (15), spices (7), nuts (4), tea substitute (2), liquor making materials (3) oils and fats (3), and culinary coagulants (1). WEPs are used in a number of different ways, including as fuelwood, feed, and medicine. Food substitute plants accounted for the majority of the top 27 wild food plants identified by RFC and CFSI. It was observed that farmers have more knowledge of WEPs, and moderate education level informants reported less WEPs used. CONCLUSION The WEPs used by the Dulong people are diverse and abundant in the Dulongjiang region. In the future, WEPs such as Maianthemum atropurpureum, Caryota obtusa, Cardiocrinum giganteum, and Angiopteris esculenta with economic potential can be developed to provide a source of income for the residents. More studies of the nutritional value, chemical composition, and biological activities of WEPs are needed. The demands and development of local communities can be realized under the premise of protecting WEPs and the associated traditional knowledge. More attention should be paid to the value of WEP and underutilized plants during future rural development.

Regional Features and Spatial Distribution of Fifty-Eight Ethnic Groups in Southwest China. SUSTAINABILITY 2021. [DOI: 10.3390/su132413570] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 01/05/2023]
Abstract
Eco-environmental variability was the basis of ethnic diversity with a persistent influence on the regional development. The unique geographic conditions and multi-ethnic characteristics in southwest China were valuable for exploring sustainable development of ethnic regions. In this study, the regional features of distribution areas of ethnic groups in southwest China were analysed, and it was found that average altitude, slope, water coverage and water form ratio of each ethnic group differed apparently. Additionally, regional features of southern minorities were relatively stable, while those of northern minorities changed evidently from 1990 to 2010. Furthermore, taking the spatial coordinates and regional features as parameters, fifty-eight ethnic groups were clustered into six categories via spatial cluster analysis. Moreover, based on the county-level population data, the ethnic similarities in southwest China were identified by correlation analysis, and the results were in accordance with those of spatial cluster analysis but more detailed. In addition, the eco-environmental adaptability of various ethnic groups was discussed in terms of living and production as well as regional sustainable development. This research was of referential meaning for population settlement, natural resources utilization and biodiversity conservation in multi-ethnic regions.
