已知土壤中的金属会对许多生物群体的健康产生负面影响，但尚不清楚它们是否会影响植物-传粉者的相互作用，以及访问在受污染土壤上生长的植物的传粉者是否有可能摄入潜在的有毒资源。我们解决花蜜中的金属的存在是否改变觅食行为的熊蜂操纵花蜜与两种常见的土壤污染物（铝或镍）在凤仙花（凤仙花科）。虽然花蜜中铝的存在并没有影响熊蜂觅食模式，鲜花含有镍花蜜解决方案访问了较短的时间内相对于控制，并劝阻蜜蜂访问附近的镍污染的花朵。然而，由于大黄蜂仍然访问这些花，它们可能摄入了潜在的有毒资源。我们的研究结果表明，土壤中的金属可能会级联产生负面影响传粉者在金属污染的环境。(c)2013爱思唯尔有限公司保留所有权利。
Metals in soil are known to negatively affect the health of many groups of organisms, but it is unclear whether they can affect plant-pollinator interactions, and whether pollinators that visit plants growing on contaminated soils are at risk of ingesting potentially toxic resources. We address whether the presence of metals in nectar alters foraging behavior by bumblebees by manipulating nectar with one of two common soil contaminants (Al or Ni) in flowers of Impatiens capensis (Balsaminaceae). While the presence of Al in nectar did not influence foraging patterns by bumblebees, flowers containing Ni nectar solutions were visited for shorter time periods relative to controls, and discouraged bees from visiting nearby Ni-contaminated flowers. However, because bumblebees still visited these flowers, they likely ingested a potentially toxic resource. Our findings suggest that soil metals could cascade to negatively affect pollinators in metal contaminated environments. (c) 2013 Elsevier Ltd. All rights reserved.
