野生熊蜂是农作物和野生植物的主要授粉者，这些植物依赖于花卉资源的持续可用性。更好地了解花食物资源的时空可用性和使用可能有助于促进熊蜂及其在农业景观中的授粉服务。我们将熊蜂的殖民地。在24个具有不同程度花卉资源可用性的农业景观中，评估了群落生长和适合度的不同参数。我们估计花粉可用性在不同时期的殖民地发展的基础上的详细信息的熊蜂花粉饮食和空间分布的访问植物物种。总花粉可用性并没有显着解释殖民地的增长或健身。然而，当使用栖息地地图时，殖民地的重量增加，女王细胞的数量，殖民地的存活率随着距离森林的增加而下降。更好地解释熊蜂性能的森林接近比（植物推断）花粉的可用性表明，其他功能的森林比花粉供应是重要的。保护农田附近的森林可能有助于维持这些重要的野生授粉者的高种群，并加强其作物授粉服务。结合不同的映射方法可能有助于进一步理清B之间的复杂关系。陆生植物及其在农业景观中的生态环境
Wild bumblebees are key pollinators of crops and wild plants that rely on the continuous availability of floral resources. A better understanding of the spatio-temporal availability and use of floral food resources may help to promote bumblebees and their pollination services in agricultural landscapes. We placed colonies of Bombus terrestris L. in 24 agricultural landscapes with various degrees of floral resource availability and assessed different parameters of colony growth and fitness. We estimated pollen availability during different periods of colony development based on detailed information of the bumblebee pollen diet and the spatial distribution of the visited plant species. Total pollen availability did not significantly explain colony growth or fitness. However, when using habitat maps, the weight gain of colonies, the number of queen cells, and colony survival decreased with increasing distance from the forest. The better explanation of bumblebee performance by forest proximity than by (plant-inferred) pollen availability indicates that other functions of forests than pollen provision were important. The conservation of forests next to agricultural land might help to sustain high populations of these important wild pollinators and enhance their crop pollination services. Combining different mapping approaches might help to further disentangle complex relationships between B. terrestris and their environment in agricultural landscapes.
