动物授粉的世界作物所提供的营养素以前没有作为衡量授粉服务价值的生物物理措施进行过评估。这项研究评估了动物授粉的世界作物的营养成分。根据Klein等人（2007）的研究，我们采用粮农组织的作物生产数据、美国农业部的营养成分数据和传粉者依赖性数据，计算了世界作物中不同营养成分的传粉者依赖性和独立性比例。完全或部分依赖于动物授粉的作物含有超过90%的维生素C，全部番茄红素和几乎全部的抗氧化剂β-隐黄素和β-生育酚，大部分脂质，维生素A和相关的类胡萝卜素，钙和氟化物，以及大部分叶酸。因此，持续的传粉媒介减少可能会加剧目前为全球人口提供营养充足的饮食的困难。
The contribution of nutrients from animal pollinated world crops has not previously been evaluated as a biophysical measure for the value of pollination services. This study evaluates the nutritional composition of animal-pollinated world crops. We calculated pollinator dependent and independent proportions of different nutrients of world crops, employing FAO data for crop production, USDA data for nutritional composition, and pollinator dependency data according to Klein et al. (2007). Crop plants that depend fully or partially on animal pollinators contain more than 90% of vitamin C, the whole quantity of Lycopene and almost the full quantity of the antioxidants beta-cryptoxanthin and beta-tocopherol, the majority of the lipid, vitamin A and related carotenoids, calcium and fluoride, and a large portion of folic acid. Ongoing pollinator decline may thus exacerbate current difficulties of providing a nutritionally adequate diet for the global human population.
