概括

植物中含有的植物毒素,如花蜜,降低了熊蜂在炎热期间控制体温的能力. 这会影响蜜蜂的健康和授粉,即使在乳蜜中发现的低剂量也会影响.

科学领域:

生态生态学生态生态学
毒理学毒理学毒理学
昆虫学昆虫学是一门学科.

背景情况:

熊蜂是全球人口下降的重要授粉者.
花蜜提供营养,但可能含有有毒的二次化合物,影响蜜蜂健康.
植物毒素可能会影响蜜蜂的温度调节,类似于农药对耐热性的影响.

研究的目的:

为了研究花蜜中有毒的二次化合物如何影响热应激下的熊蜂温度调节.
为了确定ouabain,一个cardenolide和天然花蜜来源对蜜蜂热耐受性的影响.

主要方法:

熊蜂被养了不同度的豆,乳蜜和不同种类的蜂蜜.
在模拟的热应激事件中评估了耐热度.
研究了两种熊蜂物种的效应,它们的乳访问率不同.

主要成果:

在热应激过程中,增加奥阿巴因度显著降低了熊蜂的温度调节.
在现场现实的和行为相关的度下,Ouabain影响了热耐受性.
乳草花蜜对热耐受性产生了类似的负面影响,与大多数测试的蜂蜜不同.

结论:

饮食中的植物防御毒素可能对大熊蜂的压力反应产生次致命影响.
蜜汁中含有的毒素,特别是卡德诺利德,对蜜蜂的温度调节和生存构成威胁.
了解这些影响对于大熊蜂的保护和生态系统健康至关重要.

关键词:

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.
