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 (or Huastec) in Mexico and their distribution within and between the different land-use systems along a tropical altitudinal gradient. 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 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.

生物多样性丧失和气候危机等全球紧急情况促使我们在复杂的本土农业系统中识别作物遗传资源并将其纳入主流,以了解它们作为遗传库的作用,并确定生产性景观中发展、保护和粮食安全之间的协同作用。我们旨在描述墨西哥(或瓦斯特克)食物植物的种间和种内多样性,以及它们在热带海拔梯度上不同土地利用系统内部和之间的分布情况。农民们在轮作玉米田、农林业系统和家庭菜园中管理着高度多样化且动态变化的食物生物群。即使样本量较小,我们的研究也对研究区域内的粮食作物多样性进行了全面分析。(该地区的人们)种植了大量347种已登记的物种和变种,其中大多数位于中等海拔地区。种内多样性占主导(69%)。农业生态系统复合体的所有土地利用系统都是植物遗传资源的特定库,系统之间以及系统内部和不同地点之间的相似度较低,尤其是在种内水平。珍稀独特食物植物的比例很高。我们建议采用农业生态系统方法并优先进行保护,以及开展与原地作物遗传资本相关的其他工作。
