动物授粉是生态系统为人类提供的重要服务之一。面对潜在的全球授粉危机，重要的是评估哪些国家可能更容易受到影响，以便优先考虑授粉者保护工作。贫困程度、人口密度和粮食供应对授粉者的依赖程度是确定脆弱国家的关键因素。我们评估这些方面，并确定在墨西哥，一个发展中国家和人口稠密的国家的人类食物供应依赖传粉者的水平。墨西哥农作物种类的多样性非常高。近85%的水果和/或种子消费物种在某种程度上依赖于传粉者的生产力。总的来说，与非授粉依赖作物相比，授粉依赖作物的收入更高，但种植面积更小，产量更少。然而，单位面积的体积以及单位面积的收入对于依赖授粉者的作物来说要高得多。本地野生传粉者在墨西哥驯化植物物种的果实或种子生产以及许多有用的野生物种的繁殖中也发挥着关键作用。因此，确保免费授粉服务在墨西哥特别重要，因为很大一部分人口的生计完全和直接依赖于生态系统服务来维持生计。可行的保护战略包括向努力保护或恢复植物资源和本地传粉者的Ejidos（社区土地保有制度）支付环境服务费，并建立新的自然保护区，确保传粉者的食物供应、交配和筑巢地点。(C)2009爱思唯尔有限公司保留所有权利。
Animal pollination is one of the essential services provided by ecosystems to humans. In the face of a potential worldwide pollination crisis it is important to assess which countries may be more vulnerable in order to prioritize pollinator conservation efforts. The poverty level, the population density and the level of pollinator dependence for food provisioning are key aspects to identify vulnerable countries. We evaluate these aspects and determine the level of human food provisioning dependence on pollinators in Mexico, a developing and highly populated country. The diversity of crop species in Mexico is exceptionally high. Nearly 85% of fruit and/or seed consumed species depend to some degree on pollinators for productivity. Overall, pollinator-dependent crops generate larger income but cover a lower cultivated area and produce less volume compared to non-pollinator-dependent crops. Volume per unit area, however, as well as revenue per unit area, is much higher for pollinator-dependent crops. Native wild pollinators also play a key role in fruit or seed production of Mexican domesticated plant species and in the reproduction of many useful wild species. Thus, assuring free pollination services is particularly important in Mexico as the livelihood of a large proportion of the population exclusively and directly depends on ecosystem services for subsistence. Feasible conservation strategies involve the payment of environmental services to Ejidos (communal land tenure systems) making efforts to protect or restore plant resources and native pollinators, and the creation of new protected natural areas, which ensures food provision, mating and nesting sites for pollinators.
