Traditional medicinal plant knowledge under anthropogenic pressure: evidence from the Middle Syrdarya botanical-geographical district, Uzbekistan

Zokir Kosimov — 2026-04-18

Background: Strong anthropogenic transformation in semi-arid regions substantially alters native vegetation and threatens traditional medicinal plant knowledge. The Middle Syrdarya botanical-geographical district represents one of the most intensively modified landscapes in Central Asia, where natural ecosystems have largely been replaced by agroecosystems. Integrated assessments are therefore required to evaluate medicinal plant diversity, adventive components, and the persistence of ethnobotanical knowledge under such conditions.

Methods: Field surveys were conducted between 2021 and 2025 across major landscape types of the Middle Syrdarya region. Medicinal plant species were recorded using floristic inventories, herbarium collections, and semi-structured interviews with local informants. Taxonomic composition, functional use categories, and adventive status were analyzed. The proportion of adventive species was applied as an indicator of floristic transformation, and functional traits were evaluated to assess ecosystem-related services of medicinal plants.

Results: A total of 245 medicinal plant species belonging to 158 genera and 47 families were documented. Asteraceae (49 species), Fabaceae (19), and Lamiaceae (17) were the most species-rich families. Fifty-six species (22.9%) were identified as adventive, indicating pronounced anthropogenic influence on regional flora. Adventive representation was highest in Solanaceae (71.4%) and Malvaceae (54.5%), while no adventive medicinal species were recorded in Polygonaceae. Functional analysis revealed dominance of weed and melliferous species, suggesting that medicinal resources are increasingly derived from secondary and agroecosystems. Traditional knowledge was found to be reorganized around ecologically plastic and widespread species, whereas narrowly adapted aboriginal taxa are gradually disappearing from local practice.

Conclusions: The high proportion of adventive medicinal plants reflects reduced ecosystem stability and ongoing floristic restructuring in the Middle Syrdarya region. Medicinal plants and associated traditional knowledge act as sensitive bioindicators of anthropogenic transformation. These findings provide a scientific basis for monitoring, conservation prioritization, and sustainable management of medicinal plant resources in transformed semi-arid landscapes.

Plants in Caucasian ritual bread traditions: An ethnobotanical and etymological study

Lela Chotalishvili — 2026-04-06

Background: The Caucasus maintains rich ethnobotanical traditions where plants play central roles in religious and ritual practices. In recent decades, however, much of this traditional knowledge has been lost. While medicinal and food plants have been studied, the ritual significance of plants in food preparation and etymological connections between vernacular plant names and ancient religious practices remain unexplored. This study examines plant use in ritual bread traditions across three Caucasian regions.

Methods: The research is based on semi-structured interviews and participant observation conducted in 2024-2025 in three geographical regions of the Caucasus: Svaneti, the Pankisi Gorge, and the Adjara-Kobuleti region. Plants mentioned by informants were identified in collaboration with local populations, linguists, and botanical experts. Etymological analysis was conducted using comparative-linguistic methods and published etymological dictionaries.

Results: Three ritual bread traditions were documented: Svan kut-lemzir, Kist ch'aabilg, and Adjaran sisamiani khach'ap'uri. In these traditions, plants serve not only as culinary ingredients for fermentation and aromatization but also as essential ritual elements. The study focuses on three plants − kut-k'vakh (Plantago major L., Plantago lanceolata L.), kho (Humulus lupulus L.), and sisami (Nigella sativa L.) − revealing how botanical knowledge, linguistic terms, and ritual practice are connected. Their vernacular names reflect Proto-Iranian, pre-Greek, and Kartvelian roots associated with ancient religious practices.

Conclusions: Ritual bread-baking traditions remain vibrant − families continue to pass down both the practical techniques and the ritual knowledge. Plant names carry cultural memory of pre-Christian practices and cross-cultural contact. Documenting these traditions helps preserve cultural heritage and the diversity of local plant uses. Future research should expand to other Caucasian regions.

Keywords: Caucasus, ethnobotany, ritual bread, traditional knowledge, plant name etymology.

Ethnobotanical study of aromatic and medicinal plants used by women of reproductive age in Taza (Morocco) and modeling of their satisfaction through a machine learning approach

Ibtissam Rhbibou — 2026-04-22

Background: The use of aromatic and medicinal plants (AMPs) remains widespread in Morocco, despite advances in modern healthcare and a lack of data on their safety. In Taza province, which is distinctive nationally for its floristic diversity, no studies had previously been conducted on the use of AMPs among women of reproductive age, to the best of our knowledge. The objective of this study was therefore to identify and document the use of such plants among this population.

Methods: An ethnobotanical survey was conducted in both urban and rural settings, involving 430 women aged 15 to 49. The collected data were analyzed through descriptive statistics, ethnobotanical indices, linear regression, and by mobilizing association rules (AI approach), for the first time, to reveal usage profiles that link consumed plants to the participant’s satisfaction, thus offering predictions of perceived efficacy and tolerance.

Results: All the participants (100%) used medicinal plants. 70 plant taxa belonging to 32 families were recognized, with the most represented families being Verbenaceae (FIV = 30.2%), Lauraceae (FIV = 13%), and Lamiaceae (FIV = 10.68%); and the most frequently used species: Origanum compactum Benth. (RFC = 0.595) and Salvia rosmarinus Spenn. (RFC = 0.588). Leaves were the most frequently used component (77.5%), decoction was the most commonly used preparation (76.9%), and administration was mainly oral (97.2%). Perceived effectiveness was closely associated with the level of satisfaction (χ² = 66.5; p < 0.001) and the lack of side effects (χ² = 34.1; p < 0.001).

Conclusion: Thereafter, the studied women have an ancestral knowledge and use a diversity of plants for their health and well-being in Taza. Their satisfaction is linked to plant’s effectiveness and safety. Hence, future pharmacological investigations are required for safe use of local AMPs.

Comparative ethnobotanical analysis of medicinal plants in the Western Tien Shan Transboundary Region using an integrated approach: A comparison with the Nurata Range

Zokir Kosimov — 2026-04-18

Background: Mountain ecosystems of Central Asia represent key centers of biological and cultural diversity, yet comparative quantitative assessments of medicinal plant use across ecologically contrasting mountain systems remain limited. This study aims to evaluate the ethnobotanical significance of medicinal plants in the Western Tien Shan transboundary region and compare the results with the Nurata Range using an integrated assessment model.

Methods: Medicinal plant species were selected based on documented traditional use and confirmed occurrence within each region. A total of 185 species from Western Tien Shan and 110 species from Nurata were evaluated using the Ethnobotanical Value Index (EVI), calculated as the mean of five equally weighted parameters: use diversity, chemical richness, plant part diversity, preparation diversity, and additional functional value. Floristic similarity between regions was assessed using the Jaccard similarity coefficient.

Results: Western Tien Shan exhibited higher species richness, while Nurata showed a higher mean EVI value (2.97 vs. 2.32), indicating stronger knowledge concentration. A greater proportion of high-EVI species (≥3.0) was recorded in Nurata, whereas Western Tien Shan displayed a more dispersed distribution across value categories. Jaccard analysis (J = 0.45) revealed moderate similarity, with 91 shared species and substantial regional differentiation.

Conclusion: The findings demonstrate that species richness and ethnobotanical use intensity represent distinct structural dimensions of traditional knowledge systems. The integrated EVI framework provides a quantitative basis for prioritizing medicinal plant species and supports conservation-oriented management strategies in transboundary mountain ecosystems of Central Asia.

Ethnobotany in science education: A pathway for biology teachers to engage with climate change and local knowledge

Fernanda Melo Gomes — 2026-04-11

Background: Ethnobotany is an essential science for biocultural conservation and climate resilience, helping explain human-plant relationships in socio-ecological contexts. However, integrating Local Ecological Knowledge (LEK) and climate change into science education remains challenging in schools serving traditional and socially vulnerable communities, due to curricular rigidity, limited resources, and disconnection between curricula and local realities. This study investigates how Brazilian Biology teachers navigate these barriers in their pedagogical practices.

Methods: Using mixed methods, we conducted semi-structured questionnaires and interviews with Biology teachers from eight public schools across Brazil's North, Northeast, and South regions, selected for socio-environmental vulnerability and proximity to traditional communities. Analysis included thematic coding, descriptive statistics, Spearman's correlations (ethnobotany inclusion × teacher self-efficacy), and Fisher's exact test for regional Didactic Sequences (DS) adoption patterns.

Results: While 92% of teachers acknowledge ethnobotany's relevance, implementation revealed structural gaps. Curricula prioritized curriculum-based botanical content (morphology: 64%; reproduction: 55%) over LEK-related themes (medicinal plants: 36%; Unconventional Food Plants: 27%). Climate change education relied predominantly on expository methods (78%), with place-based strategies being marginal. DS adoption was low, with no significant regional association (p = 0.776). Three barriers were identified: 1) disconnection between curricula and community knowledge, 2) lack of contextualized materials, and 3) structural constraints in teacher training.

Conclusions: Despite barriers, pedagogical resilience emerged through school gardens, community-based projects, and locally adapted DS. We recommend co-developing materials with communities strengthening teacher training through intercultural and place-based approaches and building collaborative networks between schools and universities to embed ethnobotany and climate justice within science curricula.

Taxonomic diversity and ethnobotanical importance of adventive medicinal plants in the urban flora of Andijan city (Uzbekistan)

N.M. Sidikjanov — 2026-04-20

Background: Urban ecosystems are characterized by intensive anthropogenic transformation that facilitates the spread of adventive plant species. Many of these species possess medicinal properties and are widely used in traditional ethnobotanical practices. However, the taxonomic diversity and ethnobotanical importance of adventive medicinal plants in urban flora remain insufficiently studied in many regions, including Uzbekistan.

Methods: Floristic surveys were conducted in different urban habitats of Andijan city (Uzbekistan) during the vegetation seasons of 2019–2023 using route (transect) methods. Plant identification was carried out based on regional floristic literature and herbarium materials. Ethnobotanical information on medicinal plant use was compiled from published scientific and ethnobotanical sources.

Results: A total of 66 medicinal plant species belonging to 61 genera and 22 families were recorded in the urban flora of Andijan city. The taxonomic spectrum showed that the majority of species belong to the families Asteraceae, Fabaceae, Brassicaceae, Lamiaceae, and Polygonaceae, which represent the dominant medicinal plant groups in the urban environment. Ethnobotanical analysis revealed that many species are traditionally used for treating digestive, respiratory, inflammatory, and skin-related diseases. However, medicinal plants growing in urban environments may accumulate heavy metals and other anthropogenic pollutants originating from transport emissions, industrial activities and contaminated soils. Therefore, the safety of medicinal plants collected from urban habitats should be carefully evaluated before their use in traditional medicine.

Conclusions: The results highlight the ecological and ethnobotanical importance of adventive medicinal plants as a significant component of urban biodiversity. The findings contribute to a better understanding of the role of adventive species in urban ecosystems and emphasize the need to consider ecological safety when using medicinal plants collected from urban environments.

Initial introduction of selected promising foreign medicinal species for establishing a collection of essential-oil plants

Dilovar T. Khamraeva — 2026-04-01

Background: The article presents the results of the initial introduction of several promising foreign medicinal plants aimed at establishing a collection of essential-oil species at the Tashkent Botanical Garden. The obtained data can be used to expand the assortment of medicinal and essential-oil plants, as well as to develop specialized collections and implement new crops in agricultural practice.

Methods: Phenological observations and biometric measurements (Shulz 1981) were carried out throughout the growing season of essential-oil plants in 2025. Following the traditional methodology of phenological observations (Methodology… 1975), the dates of the following phenological phases were recorded: onset of vegetation, beginning of budding, flowering period, fruit ripening, and end of the growing season.

Results: Under the agrocenosis conditions of the Botanical Garden, the introduced species (Agastache scrophulariifolia, Dracocephalum moldavica, Hyssopus ambiguus, Leonurus cardiaca, Monarda citriodora, Nigella damascena, Origanum laevigatum, Salvia deserta, Scutellaria albida subsp. colchica, Scutellaria altissima) reached the flowering and fruiting phases during their first year of vegetation. For Salvia hispanica, flowering was observed in the second half of October; however, due to a sharp temperature drop, flowering and seed formation were interrupted, and viable seeds were not obtained. In Scutellaria albida subsp. colchica, Scutellaria altissima, and Nigella damascena, self-seeding and rapid transition to generative stages were recorded, indicating their successful adaptation to the introduction conditions. Analysis of flowering times showed a shift compared to their natural habitats, with the introduced species being classified into five groups based on the onset of flowering.

Conclusion: The introduced species (Hyssopus ambiguus, Origanum laevigatum, Agastache scrophulariifolia, Leonurus cardiaca, Monarda citriodora, Dracocephalum moldavica, Scutellaria albida subsp. colchica, Scutellaria altissima, Salvia deserta, and Nigella damascena) of alien flora successfully completed a full ontogenetic cycle and produced viable seeds during their first year of vegetation under the conditions of the Botanical Garden. Salvia hispanica is characterized by genetically determined short-day flowering without photoperiodic variability and, considering the successful seed formation in the subtropical zone of Uzbekistan, can be recommended for cultivation in the Surkhandarya region. Scutellaria albida subsp. colchica, Scutellaria altissima, and Nigella damascena successfully regenerate through self-seeding and partially proceed to generative development, indicating their good adaptation to the new growth conditions.

Evaluation of the ethnobotanical importance of Chromolana odorata (L.) R.M.King & H.Rob. and Mesosphaerum suaveolens (L.) Kuntze, two invasive alien plant species in southern and central Benin

Gorgias Aikpon — 2026-04-23

Background: Traditional medicinal knowledge remains a major source of healthcare for rural communities in developing countries. Chromolaena odorata and Mesosphaerum suaveolens, native to tropical America and invasive in Africa and Asia, are widely used in traditional medicine despite their ecological impacts. This study documents and compares the ethnobotanical uses, preparation methods, and cultural importance of these two invasive species.

Methods: An ethnobotanical survey was conducted among 196 respondents selected using purposive sampling in rural communities of central and southern Benin. Data were collected from May to July 2025 using structured questionnaires to document uses, use categories, local names, plant parts, and preparation methods of both species. Relative Frequency of Citation (RFC) and Use Value (UV) indices were calculated to assess species importance. Associations between sociocultural groups and use categories were analysed using chi-square and Fisher’s exact tests, and Correspondence Analysis.

Results: Twelve distinct vernacular names were identified for both species combined, five for C. odorata and seven for M. suaveolens, reflecting sociocultural variability in their designation. Three main categories of use were identified: medicinal, veterinary, and repellent. Among the different use categories, medicinal use was the most frequently cited for C. odorata (RFC = 55.6%) and M. suaveolens (RFC = 57.6%). Repellent use was markedly higher for M. suaveolens (RFC = 49.4%) than for C. odorata (RFC = 12.2%), while veterinary use remained limited for both species (RFC ≈ 11%). Leaves were the most used plant part, and preparation methods mainly included decoction, infusion, trituration, and inhalation. Statistical analyses revealed significant associations between sociocultural groups and use categories (p < 0.001).

Conclusions: These findings highlight the widespread use of both species in traditional healthcare practices despite their invasive status. The reported uses of C. odorata and M. suaveolens highlight their potential relevance for the development of plant-based pest management strategies and emphasize the importance of documenting local ethnobotanical knowledge.

Conservation of Tupistra (Tupistra nutans Wall. ex Lindl and T. wattii (C.B. Clarke) Hook.f.) aids its ecology and ethnobotany in Darla, Chhukha, Bhutan

Prabhat Mukhia — 2026-04-22

Background: Tupistra nutans Wall. ex Lindl and T. wattii (C.B. Clarke) Hook.f. are useful species grown wild in Bhutan. Former has now been hailed as a climate-smart species as it grows elsewhere in transition and ruderal areas, needs little effort in cultivation, and has historically been used in rural livelihood. T. nutans have been extensively cultivated, collected, and used to address the current changes, urging timely documentation and conservation.

Methods: Ethnomedicinal plants and the ethnobotany and ecology of T. nutans were assessed following interviews with 78 household members inhabiting Darla, Chhukha, Bhutan.

Results: A linear relationship was observed between planting space and T. nutans inflorescence per year, as Pearson’s bivariate correlation coefficient showed significant values (r = 0.48, p< 0.012). The species is now increasingly cultivated and sustainably managed in forests, resulting in growing uses for its parts in the household economy and primary health care, and supporting the theory of availability. Almost all parts (inflorescence, leaf, root, seed) of T. nutans are useful for ethnomedicine. A total of 83.33% of the population (n = 65) used T. nutans, followed by 59 used Swertia chirayita (Roxb.) Karsten and Bergenia ciliata (Haw.) Sternb.

Conclusions: Use value shows that T. nutans can be used as a source of nutrition and a future constituent of traditional medicine. Continued research on commercial cultivation and sustainable utilization of T. nutans should be sustained, as it is considered a potential climate-smart crop to benefit the larger society.

Prateep Panyadee — 2026-04-14

Background: Senna siamea (khilek) is a common bitter vegetable and medicinal plant in mainland Southeast Asia. In Nakhon Chum, Kamphaeng Phet Province, a unique full-moon ritual known as Pli Ya transforms the local khilek curry (kaeng khilek) into a medicinal dish believed to protect health and bring good fortune.

Methods: Ethnobotanical data were collected through semi-structured interviews with community elders, direct observation of the 2025 Pli Ya ritual, and photographic documentation. Field notes were supported by informal discussions with local cooks and ritual participants.

Results: Households prepare kaeng khilek using young buds gathered before sunrise on the full moon of the twelfth lunar month. The curry, shared within the community, symbolizes both food and medicine, reflecting beliefs that moonlight enhances the plant’s healing properties.

Conclusions: The Pli Ya tradition of Nakhon Chum illustrates the fusion of ecology, belief, and healing in Thai ethnobotany. It exemplifies how ritual timing and shared food practices sustain cultural memory and the concept of “food as medicine.”

Keywords: Senna siamea, khilek, full-moon ritual, ethnobotany, Thailand

Ethnobotanical and biophysical properties of wood species used in the traditional Uzbek cradle (beshik)

О.К. Khojimatov — 2026-04-18

Background: Traditional infant care systems constitute an important component of cultural heritage shaped by long-term interactions between human societies and their natural environment. In Central Asia, the Uzbek cradle (beshik) represents a distinctive traditional infant care device that integrates cultural practices with ecological and functional design. Despite its widespread use, the ethnobotanical basis and biophysical properties of materials employed in cradle construction remain insufficiently investigated.

Methods: Ethnobotanical data were collected through semi-structured interviews with 46 traditional craftsmen across four regions of Uzbekistan (Tashkent, Fergana, Samarkand, and Kashkadarya). The study integrated ethnographic observations, literature analysis, and comparative assessment of material properties. Tree species used in cradle construction were identified and taxonomically verified using international botanical databases, and their functional and cultural roles were systematically analyzed.

Results: The study identified four principal tree taxa used in cradle construction: Salix spp., Populus spp., Morus alba L. and Juglans regia L. Among these, Salix spp. was the dominant material, accounting for approximately 89-90% of cases, primarily due to its high elasticity, low density, and ease of processing. In contrast, Morus alba and Juglans regia were mainly associated with symbolic and cultural functions. Structural analysis demonstrated that the cradle incorporates a semi-arched support system capable of generating rhythmic, low-amplitude oscillations, which may contribute to infant stabilization and comfort. Additionally, ethnobotanical practices involving aromatic and medicinal plants were documented.

Conclusions: The findings indicate that the Uzbek cradle represents an integrated system shaped by traditional ecological knowledge, combining functional material selection with cultural values. This interdisciplinary approach elucidates the relationships between plant resources, traditional craftsmanship, and infant care practices, and provides a scientific basis for future research on ethnobotanical systems and biofunctional design.

Floristic diversity of ethnomedicinally important Artemisia species in Pakistan: An extensive overview of their distribution across regions, native status and global conservation concerns

Adil Hussain — 2026-04-14

Background: Pakistan is recognized for its rich diversity of medicinal plants, with the genus Artemisia representing an ecologically and ethnobotanically important component of the flora. This review synthesizes information on distribution of reported Artemisia species across Pakistan with emphasis on their native status and conservation concerns.

Methods: The data for this review was systematically searched across various reputable scientific databases, including Web of Science, Scopus, MEDLINE and ScienceDirect using specific keywords.

Results: Earlier floristic treatments, including the Flora of Pakistan, documented 38 Artemisia species from various regions. The present compilation records a total of 66 species, reflecting a substantial increase in documented diversity from Pakistan. Growth-form analysis shows that herbaceous taxa dominate the genus in Pakistan (34 species), followed by shrubs (15 species). Most species are perennial (48 species), while annuals constitute a smaller fraction (6 species) with a few species exhibiting biennial or mixed life cycles. According to Plants of the World Online (POWO), Artemisia species in Pakistan occur primarily in temperate, subalpine, subtropical and desert habitats indicating broad ecological adaptability across altitudinal and climatic gradients. Of the 66 species recorded, 45 are mentioned as native to Pakistan, whereas the native status of 21 species remains unclear. The Flora of Pakistan and POWO revealed 38 species listed in both but only 31 species are consistently shared, highlighting taxonomic inconsistencies. Conservation assessments are notably limited, with only 13 species (20%) evaluated at the global level.

Conclusion: The increase in reported species from 38 to 66 in Pakistan may reflect improved taxonomic resolution, expand geographic surveys and increased ethnobotanical research and may or may not be an expansion of the genus in Pakistan. To confirm this, future studies should prioritize underexplored regions resolve taxonomic ambiguities and integrate molecular and ecological approaches to better understand the diversity, conservation needs and expansion of the genus Artemisia in Pakistan.

Traditional medicinal uses, diversity, and conservation status of Malagasy aromatic plants: a review

Henintsoa Jean Baptiste Ramaminirina — 2026-04-03

Background: Madagascar is a global biodiversity hotspot, with high plant endemism. Aromatic plants are crucial for traditional medicine and for economic applications, including essential oils, cosmetics, and pharmaceutical products. However, habitat loss, overharvesting, and climate change threaten many species, and comprehensive nationwide assessments remain scarce. This study aims to provide an updated synthesis of the diversity, medicinal uses, and conservation status of Malagasy aromatic plants.

Methods: A literature-based review was conducted using 314 scientific and technical references, including peer-reviewed publications, books, theses, and institutional reports. Aromatic species were identified through essential-oil analyses, botanical descriptions, and herbarium records. Taxonomic and ecological information was compiled from the Catalogue of the Plants of Madagascar and conservation data from the IUCN Red List. Traditional medicinal uses were extracted from the CNARP database and quantified using citation frequency indices. Relationships among plant parts, disease categories, and bioclimatic distribution were explored using Correspondence Factor Analysis.

Results: This study documented 1,021 aromatic species across 285 genera and 68 families, on which 70.5% are endemic to Madagascar. Shrubs were dominant with a percentage of 47%. Essential oil composition has been reported for only 34.5% of species. Traditional medicinal uses were recorded for 473 species, commonly used in infectious diseases, digestive disorders, and traumatic injuries. Among the species assessed by the IUCN, nearly 68% fall within threatened categories (Critically Endangered [CR], Endangered [EN], and Vulnerable [VU]), indicating substantial conservation concern. Conclusions: Malagasy aromatic flora is highly diverse, medicinally important, and economically valuable, largely threatened. Ex situ conservation and sustainable cultivation of endemic species can reduce pressure on wild populations while supporting local and national economies. This study provides a critical foundation for integrated strategies in research, conservation, and sustainable utilization of aromatic plants, ensuring their continued contribution to traditional medicine and potential pharmacological innovation.

Integrating Spatial Availability into ethnobotanical research: Introducing the Spatial Availability Score (SAS)

Hamid Nazari — 2026-04-01

Background: Ethnobotanical research has traditionally emphasized the documentation of cultural importance and patterns of plant use through indices such as the Relative Frequency of Citation and Use Value. While these metrics effectively capture cultural relevance within specific knowledge systems, they overlook an important dimension: the spatial availability of plant species beyond their original ethnobotanical context. Consequently, species with comparable ethnobotanical importance may differ substantially in their feasibility for future application in food systems, medicinal use, or local resource planning due to contrasting geographic distributions.

Methods: Here, we introduce the Spatial Availability Score (SAS), a quantitative index designed to integrate geographic availability into ethnobotanical assessment. SAS is calculated using species occurrence data to estimate the extent of occurrence after spatial outliers are identified and removed through a reproducible statistical procedure based on multivariate distance (Mahalanobis distance).

Results: The resulting measure is normalized within a defined geographic reference area, enabling comparison among species at spatial scales relevant to intended applications, from local to regional contexts. SAS is conceptually independent from existing ethnobotanical indices and is not intended to replace measures of cultural importance or use intensity. Rather, it provides complementary information on the spatial feasibility of ethnobotanical knowledge, allowing researchers and decision-makers to distinguish between culturally important species with restricted distributions and those that are geographically widespread. By explicitly incorporating biogeographic information into ethnobotanical analysis, SAS enhances the interpretability, transferability, and future-oriented relevance of ethnobotanical studies.

Ethnobotany and the Productivity-Endurability Trade-off

Zaal Kikvidze — 2026-04-18

Background: Ethnobotany serves as an exemplary interdisciplinary science, synthesizing concepts from botany, ecology, sociology, and ethnography to explore the complex relationships between human societies and plant resources. While ethnobotanical research frequently documents the superior sensory qualities, nutritional profiles, and medicinal potency of wild plants and traditional landraces compared to modern commercial varieties, these observations often lack a unified biological framework. This paper unifies these phenomena — along with the global dominance of annual plants as staple foods — within a framework of the productivity-endurability trade-off.

Methods: Rooted in the historical "law of compensation" proposed by Darwin and Wallace, this trade-off posits that biological resources allocated to one function, such as biomass accumulation (productivity), are necessarily withdrawn from others, such as stress tolerance and pest resistance (endurability). Drawing on J.P. Grime’s C-S-R Triangle theory, this study examines how artificial selection and agricultural intensification bypass environmental constraints, often resulting in highly productive crops with significantly reduced self-defense mechanisms.

Results: Through this theoretical lens, the preference for annual staples is revealed as a strategic selection for rapid reproductive output over the high metabolic costs of perennial longevity, which are only mitigated in tropical environments. Furthermore, the trade-off explains the diminished potency of cultivated medicinal and aromatic plants; in the absence of wild environmental stressors, plants downregulate the synthesis of costly secondary metabolites that define their flavor and therapeutic value.

Conclusions: The trade-off concept provides a comprehensive explanatory framework for key ethnobotanical observations, offering critical insights for the future of sustainable breeding and global food systems.
