景观因素在形成近北极东部地区熊蜂病原体负荷中的作用

病原体和寄生虫是导致熊蜂数量下降的原因。它们的数量会受到许多非生物和生物因素的影响，因此管理这些蜜蜂的疾病需要了解这些因素对病原体负荷的相对影响。我们评估了大黄蜂（Bombus impatiens）和蜜蜂（Apis mellifera）中黑蜂王细胞病毒（BQCV）和畸形翅病毒的载量，以及大黄蜂中寄生虫Vairimorpha bombi和Crithidia bombi的载量。根据土地覆盖、花卉质量、蜜蜂多样性和天气等指标对病原体负荷进行了评估。研究结果与美国宾夕法尼亚州的类似数据以及北美其他有关熊蜂的景观研究结果进行了比较。与宾夕法尼亚州相比，北卡罗来纳州熊蜂病原体负荷的空间变化较小，这降低了检测景观效应的能力。例如，Crithidia相当普遍，而Vairimorpha则未检测到。来自这两个州的数据显示，已开发土地和蜜蜂与病毒载量（尤其是 BQCV）呈最一致的正相关，而森林和筑巢栖息地的可用性通常与病毒载量呈负相关。多变量模型仅支持北卡罗来纳州熊蜂夏季花卉资源与 BQCV 病毒量之间的正相关关系。结合更广泛的文献，这些数据表明，发达土地和蜜蜂的水平与病原体负荷的增加关系最大，而花卉资源和蜜蜂群落组成则显示出更多的环境依赖性影响。
