科学领域:

  • 生态生态学 生态生态学
  • 行为生态学 行为生态学
  • 感官生物学 感官生物学

背景情况:

  • 相似的物种经常通过各种机制来分割资源.
  • 感官变异可以驱动利基划分,减少密切相关物种之间的重叠.
  • 了解感官差异是解释社会黄蜂共存的关键.

研究的目的:

  • 为了研究两种在巴塔哥尼亚的维斯普拉物种之间对碳水化合物的感官反应是否不同.
  • 为了确定这些感官变化是否与食模式和资源开发相关.
  • 评估感官区分在促进侵入性黄蜂共存中的作用.

主要方法:

  • 实验室实验测量了Vespula germanica和Vespula vulgaris的碳水化合物反应值.
  • 实地研究分析了两种物种食碳水化合物的糖度.
  • 检查了感官敏感性,食模式和殖民地大小之间的相关性.

主要成果:
