Background: The use of medicinal plants is integral to global healthcare systems, with Sub-Saharan Africa maintaining a robust tradition of herbal medicine alongside Western-oriented healthcare. As migrant communities tend to continue traditional herbal practices after migration, documenting this use is vital to develop culturally sensitive healthcare. This study investigates plant usage and perspectives in the context of sexual and reproductive health among the Congolese community in Belgium, particularly in the Matongé quarter of Brussels. Our research questions were: (1) What is the current knowledge of medicinal plants among the Congolese community in Belgium in the context of sexual health, and what are the applications and commonly employed administration methods of these plants? (2) What role does herbal medicine play in the context of sexual health for people of Congolese descent in Belgium and how this is influenced by perceptions of sexuality? and (3) Is there a gender bias in the use of medicinal plants, and if so, can this be related to perceived gender norms?

Methods: We conducted 22 semi-structured interviews with people of Congolese descent currently living in Belgium. Participants were selected using both snowball sampling and purposive sampling. Plant use in the context of sexual health was recorded through freelisting. Data on narratives, ideas, and perceptions of this plant use in the context of sexual health were collected. Interview transcripts were analyzed using thematic analysis.

Results: We identified 17 plant species used for sexual health. Three overarching themes emerged from our data. Plants were used with a notable gender bias favoring male sexual potency enhancement. Men used these plants for both remedying potency issues and enhancing sexual prowess. In contrast, knowledge about plants for female sexual health was limited. Gender norms reinforced the importance of male sexual potency, while stigmatizing open discussions of female sexuality.

Conclusions: The use of medicinal plants for sexual health raises health, social, and conservation concerns, underscoring the need for further research in this area. This study contributes to understanding medicinal plant use within the Congolese community in Belgium and highlights the necessity for future research on herbal practices for female sexual health in this context.

This opinion piece, written by ethnobiologists from different parts of the world, emphasizes the importance of ethnobiology research in advancing contemporary biology, natural resource management, biodiversity conservation, sustainable development, and, especially, contributing to the ecological transition and more just and inclusive world. To achieve these goals, it is essential to develop research and collaborate with social groups that live in close relationship with nature in research activities, such as Indigenous Peoples and Local Communities (IPLC), as well as Afro-descendants and other Marginalized, Minority or Minoritized Communities (AMMC). Ethnobiology can identify and provide locally appropriate solutions to local problems, enabling sustainable resource management at the landscape level. The text explores important aspects that need to be considered to guide the future of ethnobiology in the next 20 years, aiming to integrate and amplify previous discussions held in the discipline and identify points that demand ongoing attention. This paper highlights reflections from diverse researchers, emphasizing how ethnobiology can embrace different perspectives and employ rigorous analysis of complex phenomena toward effective policies and practices. This approach holds the potential to address the challenges the planet is currently facing in the coming decades.

Background: The Hani people, who reside in Yuanyang County, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, rely on rice terrace farming as their primary livelihood. They utilize plants in various traditional ritual practices. The Hani people have categorized the value of plants based on their natural attributes and have refined the ways of using different plants in specific rituals through practical observations and experiences derived from their agricultural culture. Although the plants used in these rituals hold significant cultural value, they have yet to be studied from the perspective of ethnobotany. This study aims to approach the ritual plants using ethnobotanical methods.

Methods: Ethnobotanical fieldwork was conducted in 10 villages in Yuanyang County between 2021 and 2023. Data were collected from the local Hani people through semi-structured interviews and participatory observations and 41 informants were interviewed during the field investigations. The frequency of citation (FC) and relative frequency of citation (RFC) were utilized to evaluate the relative importance of ritual plants among the local communities.

Results: A total of 36 plant species, belonging to 18 families and 34 genera, were recorded as being used in 11 ritual practices by the Hani people. Rosaceae, Poaceae, and Fabaceae were found to have the highest number of species. Most of the ritual plants used by the Hani people were collected from the wild. FC and RFC analysis showed that the preferred plants for Hani rituals were Rhus chinensis Mill, Oryza sativa L., Phyllostachys sulphurea (Carr.) A. et C. Riv. and Musa basjoo Siebold & Zucc. ex Iinuma. The 11 rituals are all centered around the performance of people, crops and livestock. The Hani people use plants in different rituals mainly based on their biological attributes.

Conclusions: Many rituals of the Hani people are closely related to their production and livelihood, and the plants used in these rituals are deeply rooted in Hani's traditional ecological knowledge and beliefs. The Hani people's reverence for nature, respect for life, gratitude towards ancestors, and seeking blessings and disaster prevention for their families, crops, and livestock are all reflected in these rituals and their utilization of ritual plants. The Hani people showcase their agricultural culture in the Honghe Hani Rice Terraces through plant-based ritual performances. Studying ritual plants in the core area of the Hani Rice Terraces is of great significance for protecting the Hani Terrace farming culture. In the future, it is essential to pay more attention to the role of traditional knowledge in biodiversity conservation.

Background: Environmental perception involves the interpretation and interaction of individuals with their surroundings, influenced by cultural, social, and individual factors. Analyzing the environmental perception of children and adolescents contributes to fostering awareness and ethical behavior toward the environment. Indigenous communities, such as the Karajá from Brazil, possess significant environmental knowledge due to their connection with nature, providing distinctive insights into biodiversity and natural interconnections. In this study, the perception of fungi among Karajá indigenous children and adolescents was investigated.

Methods: The study involved 229 elementary school students from the Macaúba, Fontoura and Santa Isabel do Morro communities, located on Bananal Island, Brazil. Students were encouraged to draw what they knew about fungi and answer where they learned about fungi and what name they give to these organisms. The drawings were analyzed considering seven categories.

Results: The term most used to refer to fungi was hedoro(u) (56%), followed by fungus (21%) and mushroom (11%). Most students said they had learned about fungi in nature (38%) and at school (36%). The most represented organisms were in fact fungi (93%), mainly being portrayed in nature (94%). Most participants did not attribute any ecological function to fungi (83%), although 16% of them recognized fungi as decomposers and 1% as phytopathogenic agents. Negative aspects, particularly food contamination, were more frequently represented (13%) than positive aspects (4%). The drawings identified two morphological types: mushrooms (87%) and mold (13%). Among these mushrooms, 68% possibly represent the Amanita muscaria species.

Conclusions: Although the children and adolescents showed that they noticed the fungi around them, the group's concept and understanding were limited to the figure of the mushroom and the negative aspects related to food contamination. Strong association of the fungi with the A. muscaria is noteworthy, since it does not occur in the environment in which the participants live, suggesting that external stimuli, such as TV or the internet, can influence their perception more than the nature they are exposed to.

Background: Several hypotheses have been used in ethnobotany to explain the plant's selection criteria by people for their daily needs. Thus, it is important to assess synergy and complementarity among them, especially, those concerning the plant use value, social dynamics and human traits. The study aims to (i) highlight people's socio-economic factors, and plant ecological traits that affect the plant use-availability dynamic (PUD); and (ii) assess the available species diversity effect on ethno-medicinal knowledge diversity in Benin.

Methods: Ethnobotanical interviews were carried out to quantify the importance of local species in different ecological zones of Benin with 590 traditional medicine actors. Vegetation surveys were done to assess species availability within 337 plots of 50 m x 40 m or 60 m x 30 m, depending on the climatic zone, for a total of 61.6 ha, established in 15 forests distributed within the 10 phytodistricts of Benin. The plant use availability hypothesis was quantified as a dynamic link between species use value and availability (PUD). A general and mixed linear models were used to assess the significance of each factor's effect on PUD. Pearson correlation test was applied on Shannon diversity index considering inventoried species in the field and those which were cited by people, for the available species diversity effect on ethno-medicinal knowledge diversity assessment.

Results: A hundred and twenty woody medicinal plants, mostly trees (68.33%), were sampled. Growth form and its interaction with phytodistrict have a significant effect (p: 0.005) on PUD. The less available trees were the most used in the phytodistricts 3, 4, 8 and 10. PUD varies significantly according to social factors (p: 0.007). Ethnicity, age and main activity were the most quoted social factors which influenced the PUD. Ethnicity and age have various effects considering the phytodistricts. Moreover, the influence of age changes following the main activity. Plant selection did not solely link to the surrounding diversity (r: - 0.293; p: 0.403). Within some phytodistricts, especially those of 3, 4, 8 and 10, the less available tree species were the most requested.

Conclusion: It is urgent to reforest vegetation patches in some phytodistricts (3, 4, 8 and 10) of Benin with widely requested and no available species to avoid the extinction of their wild populations. This concerns Cassia sieberiana DC., Anonychium africanum (Guill. & Perr.) C. E.Hughes & G. P. Lewis, Pterocarpus erinaceus Poir., Cola millenii K. Schum., Azadirachta indica A. Juss., Khaya senegalensis (Desr.) A. Juss., Pseudocedrela kotschyi (Schweinf.) Harms, Treculia africana Decne. ex Trécul, Uapaca heudelotii Baill., Vitellaria paradoxa C. F. Gaertn., Kigelia africana (Lam.) Benth. and Newbouldia laevis (P. Beauv.) Seem. ex Bureau.

The names of plants convey information on their appearance (shape, structure, colour), taste or smell, their uses (practical, ceremonial, magical and medicinal) as well as the beliefs and convictions associated with them. Assuming that the particular features of plants, entrenched in their names, must have been important to language users for some reason, the analysis of plant names can help reconstruct traditional knowledge about plants. The author analyses the standard and dialectal names for the black elder (Sambucus nigra) in Polish, juxtaposing the plant's features revealed in its names (linguistic data) with the cultural accounts associated with the plant ("with-linguistic" data). This allows for the reconstruction of the following features of the plant: (a) the appearance of the shrub, (b) the properties of its fruit, (c) the smell of the plant, (d) the place where it grows, (e) the time of harvesting, (f) its use in folk medicine and (g) the association of the plant with impure powers and diseases. The conducted analyses show that reaching for hard "linguistic evidence" (standard and folk names) makes it possible to compile hierarchies of the characteristics of the plants described. Situating these names against the background of "with-linguistic" data leads to the conclusion that folk nomenclature and folk knowledge enrich and complement each other. The vast number of names for the black elder with different onomasiological bases, presenting different points of view, also demonstrate the relationship between the degree of lexical differentiation and the cultural meaning of the plant. The ethnolinguistic analysis of the names for the black elder (Sambucus nigra), similarly to ethnobotanical studies of folk plant names, provides insights into past and contemporary uses of the plant. Thus, it can provide a starting point for further ethnobotanical research.
