Are Mixtec Forgetting Their Plants? Intracultural Variation of Ethnobotanical Knowledge in Oaxaca, Mexico. Erosion of ethnobotanical knowledge in indigenous communities has been reported increasingly in recent decades. This study quantitatively and qualitatively analyzed the variation of ethnobotanical knowledge in communities of the high Mixtec subregion. We interviewed 64 Mixtec about edible and medicinal plants. We evaluated the knowledge (names and knowledge of use) and the active application of the use among people of different ages, gender, education level, migrants, and non-migrants. In general, increasing age, female gender, decreasing formal education, and non-migration are positively correlated with the knowledge and use of plants. The most alarming finding concerns the knowledge of the Mixtec names of plant-people under 30 years old no longer know them. We envision a process of transition and adaptation of the knowledge and uses of plants, but inevitably enormous ethnobotanical knowledge is quickly disappearing along with the Mixtec language. ¿Los mixtecos están olvidando sus plantas? Variación intracultural del conocimiento etnobotánico en Oaxaca, México. La erosión del conocimiento etnobotánico en las comunidades indígenas se ha informado cada vez más en las últimas décadas. Este estudio analizó cuantitativa y cualitativamente la variación del conocimiento etnobotánico en comunidades de la subregión Mixteca alta. Entrevistamos a 64 mixtecos sobre plantas comestibles y medicinales. Evaluamos el conocimiento (nombres y conocimiento de uso) y la aplicación activa del uso entre personas de diferentes edades, género, nivel educativo, migrantes y no migrantes. En general, el aumento de la edad, el género femenino, la baja educación formal y la no migración se correlacionan positivamente con el conocimiento y uso de las plantas. El hallazgo más alarmante se refiere al conocimiento de los nombres mixtecos de las plantas: las personas menores de 30 años ya no los conocen. Visualizamos un proceso de transición y adaptación del conocimiento y usos de las plantas, pero inevitablemente un enorme conocimiento etnobotánico está desapareciendo rápidamente junto con el idioma mixteco.

More than Maize, Bananas, and Coffee: The Inter- and Intraspecific Edible Plant Diversity in Huastec Mayan Landscape Mosaics in Mexico. Global emergencies such as biodiversity loss and climate crisis urge us to identify and mainstream crop genetic resources in complex indigenous farming systems to understand their role as genetic reservoirs and identify synergies in productive landscapes between development, conservation, and food security. We aimed to characterize the inter- and intraspecific diversity of food plants of the Tének (or Huastec) in Mexico and their distribution within and between the different land-use systems along a tropical altitudinal gradient. Tének farmers manage a highly diverse and dynamic food biota in swidden maize fields, agroforestry systems, and home gardens. Even with a small sample size, our study provides a complete analysis of the food crop diversity in the research area. The Tének cultivate a high number of 347 registered species and variants, most of them at medium altitude. Intraspecific diversity dominates (69%). All land-use systems of the agroecosystem complex serve as a specific pool for plant genetic resources, and there is a low similarity between and within systems and localities, especially at the intraspecific level. The proportion of rare and unique food plants is high. We recommend an agroecosystem approach and prioritization for conservation as well as other efforts related to the in situ crop genetic capital.
