概括
工作蜂避免食用有金属污染的食物, 但如果替代品含糖量低, 尤其是在不照顾幼时, 这表明蜜蜂根据社会背景和食物质量来调整食.
科学领域:
- 生态学
- 环境毒理学
- 行为生态学
背景情况:
- 金属污染对野生动物构成重大威胁,
- 虽然蜜蜂的金属毒性已知,但它们检测和避免受污染的食物来源的能力以及社会因素对此的影响需要进一步调查.
研究的目的:
- 调查大黄蜂是否避免食用有金属污染的食物.
- 为了确定社会背景,特别是育儿照顾,是否会影响这种避开行为.
- 探索金属污染,食物能量含量和蜜蜂食决策之间的相互作用.
主要方法:
- 尾蜂工人可以选择含铜或的糖溶液和未受污染的替代品.
- 由于糖度的变化 (50%与20%相比) 造成了能量权衡.
- 通过比较幼虫存在和不存在的工人选择来评估繁殖护理的影响.
主要成果:
- 当两种选择均 (50%的糖) 时,工作人员始终避免使用金属污染溶液.
- 当未受污染的选项含有较低的糖分 (20%的糖分) 时,工人选择含有金属的溶液,但只有当他们不倾向于繁殖时.
- 工人优先选择没有金属的,虽然含糖量较低的溶液,这表明适应性供应.
结论:
- 蜜蜂工作者积极避免金属污染的食物来源.
- 熊蜂的食行为取决于环境,受食物质量和母蜂的存在的影响.
- 这些发现突出了蜜蜂用来平衡营养需求与环境风险的复杂适应策略,特别是在家长照顾的背景下.

314
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
