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.

不仅仅是玉米、香蕉和咖啡：墨西哥 Huastec 玛雅景观马赛克中的种间和种内食用植物多样性。生物多样性丧失和气候危机等全球紧急情况敦促我们在复杂的本土农业系统中识别和主流化作物遗传资源，以了解它们作为遗传储存库的作用，并确定发展、保护和粮食安全在生产环境中的协同作用。我们旨在描述墨西哥Tének（或 Huastec）食用植物的种间和种内多样性，以及它们沿热带海拔梯度在不同土地利用系统内部和之间的分布。特内克农民在玉米地、农林业系统和家庭花园中管理着高度多样化和动态的食物生物群。即使样本量很小，我们的研究也提供了对研究领域粮食作物多样性的完整分析。Tének种植了大量 347 种已登记物种和变种，其中大部分位于中等海拔。种内多样性占主导地位（69%）。农业生态系统综合体的所有土地利用系统都是植物遗传资源的特定库，系统和地方之间和内部的相似性较低，特别是在种内水平上。稀有和独特的食用植物比例很高。我们建议采用农业生态系统方法和优先考虑保护以及与原地作物遗传资本相关的其他努力。
