Background: Cuatrociénegas, part of the Chihuahuan Desert, is a region of unique biological, geological, geographical, and evolutionary importance. Its current population is mestizo; nevertheless, it has high national historical, cultural, and touristic relevance in Mexico. It has been cataloged as nationally significant for its flora and fauna by Mexican law, as well as being designated a High Protection site by the World Wildlife Fund and UNESCO. Because of its diverse and complex biological and sociocultural characteristics, we considered it important to determine, identify, and analyze various aspects of the traditional ethnobotanical knowledge and practices in this region. Methods: Between 2016 and 2019, seven field trips were made to document the knowledge and use of flora. Cuatrociénegas is a protected area, collecting botanical material is regulated, so specimens were photographed and collected in neighboring communities, and in public and private gardens. Later permission was obtained to complete the collection of specimens (2019–2020). The plants were identified and entered into the flora database of the state of Coahuila, and deposited in the Herbarium of the Faculty of Forest Sciences, Autonomous University of Nuevo León, Mexico. One hundred ten local residents (50 men and 60 women), aged between 27 and 91 years, were interviewed (semi-structured interviews). The cultural importance of ethnobotanical resources (cultural significance index) and its significance with respect to ethnobotanical richness in other Biosphere Reserves in Mexico (Mann-Whitney test), and similarities in the diversity of exotic species (Sørensen index) were studied. Results and discussion: The ethnobotanical information registers 158 species and 132 genera in 57 vascular and non-vascular families, documenting a greater knowledge and use of cultivated species (84) with respect to wild species (74). The diversity of plants reported is compared to other ethnobotanical studies carried out in Mexican Biosphere Reserves. These results are highly relevant, in spite of unique exotic species. The people local pay special attention to medicinal and ornamental plants. The species that presented the highest use values are Larrea tridentata, Jatropha dioica, and Machaeranthera pinnatifida, three species characteristic of the desert region. Conclusions: The particular diversity of wild flora in Cuatrociénegas Valley, combined with the varied introduced flora, is an important multifunctional resource. Special attention to introduced species is associated with harvesting use restrictions in the protected area as well as the high value of ornamental species that are difficult to maintain in desert areas. The extensive use of ethnobotanical knowledge is an example that biocultural diversity (at the conceptual level) is also strongly associated with socio-ecological systems incorporating mestizo groups and semi-urban rural landscapes, thus ceasing to be an exclusive focus of indigenous communities and regions.

Iturbide is in the northeast of Mexico and has a rich native and exotic flora; however, there are no ethnobotanical records, therefore, it requires attention in the documentation of traditional knowledge and practices of its botanical resources. In 2021, twelve field trips were carried out, applying 110 semi-structured interviews. Plant samples were collected, identified and deposited in an herbarium. We used the Chi-square test to compare the anthropocentric categories concerning others reported in Mexico. To determine the cultural importance, three ethnobotanical indices were applied (UVI, ICF and FL). We recorded 250 species with ethnobotanical implications associated with 121 genera and 83 families, including 140 native and 110 exotic species. The most common plant families were Asteraceae, Lamiaceae and Fabaceae. The main categories of uses were: ornamental, medicinal and food. The species with the highest UVI values were Lepidium peruvianum, Ocimum basilicum and Salvia rosamrinus. The multifunctionality of the native and exotic flora demonstrates the extensive knowledge associated with botanical resources. For example, the role of ornamental plants, with a direct impact on human well-being, the resilience of healers and traditional inhabitants by using different species for the treatment of various ailments or indigenous edible plants in the daily diet.

Systematic reviews and meta-analytical approach are a tool used in different social and biological disciplines, but its application in evaluating ethnobiological information is scarce. Thus, through this analytical approach, we seek to answer if there are any patterns in the mexican ethnozoological scientific production. We searched for studies published between 2005 and 2015 in catalogues, repositories and databases. For evaluating significative differences among seven variable datasets, we first used non parametric Kruskal-Wallis tests and then Tukey multiple comparison tests. We also determined the link between researchers and institutions with a multidimensional non-metric scaling analysis. We found 295 published studies, book chapters were the most representative (27%), diffusion articles (20%), impact factor articles (15%) and indexed articles (14%). There are significant differences in the number of publications among the evaluated years, among thematic areas, study focus (qualitative/quantitative), ethnographic and biological methods. Regarding academic linking, we identified 94 author adscription institutions, however, no research networks were identified. Our results suggest that the amount, diffusion and reach of mexican ethnozoological production show a tendency to non-periodic publishing, predilection for qualitative approach, a low use of statistical and ethnobiological analysis, as well as an inadequate selection of biological methods. We suggest this data analysis approach will allow a better standardization for information taking and processing, aiding the discipline in its growth and consolidation.

In Linares, Nuevo León, Mexico, there is no record of the total number of species or the uses that people make of native plants. The purpose of this study was to know the species and their uses in the municipality of Linares, Nuevo León, Mexico. Based on 180 semi-structured interviews, collection, identification, and storage of botanical specimens, the regional ethnobotanical knowledge was assessed. The ethnobotanical information and significant use of plants in Linares was studied. To identify the cultural importance of the ethnobotanical uses of the plants, three indices were calculated: the Use Value Index (UVI), the Informant Consensus Factor (ICF), and the Fidelity Level (FL). We recorded 59 plant families, 151 genera, and 152 species. The families with the largest number of genera and species with uses registered are Asteraceae, Fabaceae, Cactaceae, Araceae, and Euphorbiaceae. The most common uses recorded are ornamental, medicinal, food, and forage. The highest values for ICF were for the circulatory, endocrine, and digestive systems. At least 20 species had 100% FL index values. The species with the highest UVI values were Equisetum laevigatum, Persea ameriana, Amaranthus palmeri, Lophophora williamsii, and Artemisia ludoviciana. A wide use of native flora is recognized in Linares, Nuevo León, which directly influences the livelihood of people in the area.

Background. The indigenous and mestizo communities in Mexico have used Armillaria mellea as a non-timber forest resource, mainly as food; ecologically it is an abundant species in forests. For this reason, we establish A. mellea as a species with cultural importance and a high potential for the development of sustainable regional and ethnomycotourism projects. Methods. The field work was carried out in the Ñhöñho communities of Texquedó and Xahai, Querétaro; Mexico. Semi-structured surveys were applied to local specialists in collecting mushrooms. Species were identified at the taxonomic level. Participation-action workshops were held for the organization and development of ethnomycotourism events. Results. A total biomass of 107.11 kg of A. mellea was collected with the support of the “hongueros” (local mushroom collectors) during the rainy seasons of 2017, 2018 and 2019. A greenhouse-type solar dehydrator was designed to process the mushrooms with a minimum dehydration capacity of 30 and a maximum of 100 kg of fresh mushrooms; and value-added products were designed with edible wild mushrooms. On the other hand, tours and mushroom collections (edible and inedible) were designed with local specialists, academics and visitors; promoting and laying the foundations for the development of ethnomycotourism with an approximate economic income per year in each community of 700 to 1200 dollars. Finally, as a result of this project, the non-profit civil organization; Ethnomycology, Research and Community Development A.C. Conclusion. Mushrooms constitute the basis for the planning of regional sustainable projects, as means of revaluing traditional systems, and strengthening the local economy, as well as conservation and management under a biocultural approach.
