足够多样和丰富的资源对多面手消费者来说是必不可少的，并构成了传粉者一整套保护策略的重要组成部分。蜜蜂是多才多艺的觅食者，它们依靠不同的饲料来充分满足自己的营养需求。通过对26份蜜蜂(Apis melvena L.)在英格兰西北部的蜂箱中，我们量化了蜜蜂面包的营养成分以及从花粉中产生这些蜂箱的植物物种。以质量计，蛋白质是最丰富的营养物质(63%)，其次是碳水化合物(26%)。蛋白质和脂肪含量(但不是碳水化合物)对花卉多样性的排列有很大贡献，将饲料质量与饲料组成联系起来。核糖体DNA基因ITS2区域的DNA测序鉴定了89个不同植物属的花粉，每个蜜蜂面包样本包含6到35种花粉类型。优势属包括蒲公英(蒲公英)和樱桃(Prunus)，蒲公英(Taraxacum)和樱桃(Prunus)与蛋白质含量呈负相关，蒲公英与蜜蜂面包蛋白质含量呈正相关。此外，氨基酸(如组氨酸和缬氨酸)的比例随着花卉种类组成的不同而不同。这些结果还量化了个别植物属对蜜蜂营养的影响。我们得出结论，不同植物的花粉对寄主营养的影响是协同作用的；蜜蜂面包的花粉多样性与其营养含量有关。多样化的环境弥补了个体饲料植物的损失，因此，由于获得替代资源的限制，多样性的丧失可能会破坏消费者群体的稳定。本文的在线版本(10.1007/s00442-0173968-3)包含补充材料，可供授权用户使用。
Sufficiently diverse and abundant resources are essential for generalist consumers, and form an important part of a suite of conservation strategies for pollinators. Honey bees are generalist foragers and are dependent on diverse forage to adequately meet their nutritional needs. Through analysis of stored pollen (bee bread) samples obtained from 26 honey bee (Apis mellifera L.) hives across NW-England, we quantified bee bread nutritional content and the plant species that produced these stores from pollen. Protein was the most abundant nutrient by mass (63%), followed by carbohydrates (26%). Protein and lipid content (but not carbohydrate) contributed significantly to ordinations of floral diversity, linking dietary quality with forage composition. DNA sequencing of the ITS2 region of the nuclear ribosomal DNA gene identified pollen from 89 distinct plant genera, with each bee bread sample containing between 6 and 35 pollen types. Dominant genera included dandelion (Taraxacum), which was positively correlated with bee bread protein content, and cherry (Prunus), which was negatively correlated with the amount of protein. In addition, proportions of amino acids (e.g. histidine and valine) varied as a function of floral species composition. These results also quantify the effects of individual plant genera on the nutrition of honey bees. We conclude that pollens of different plants act synergistically to influence host nutrition; the pollen diversity of bee bread is linked to its nutrient content. Diverse environments compensate for the loss of individual forage plants, and diversity loss may, therefore, destabilize consumer communities due to restricted access to alternative resources.
