概括
蜜蜂 (Apis mellifera L.) 在资源稀缺期间表现出更高的风险耐受性,并采取更危险的食行为,如蜂蜜抢劫. 在食物稀缺时,这种风险感知和沟通的转变对于殖民地生存至关重要.
科学领域:
- 动物行为 动物行为
- 生态生态学 生态生态学
- 进化生物学 进化生物学
背景情况:
- 适应性决策包括平衡奖励和风险,蜜蜂 (Apis mellifera L.) 通常更喜欢高质量的资源,并使用摇摆舞来招募.
- 在资源稀缺的情况下,获取食物的行为发生了变化,蜜蜂接受价值较低的奖励,并参与蜂蜜抢劫,这是一种涉及窃取蜂蜜的危险策略.
- 影响食期间风险感知和沟通的因素,特别是蜂蜜抢劫期间,尚不清楚.
研究的目的:
- 测试假设,季节性资源稀缺和蜂蜜掠夺的增加与更大的采集者风险容忍度相关.
- 调查环境条件如何改变蜜蜂采集者的风险感知和社会沟通.
主要方法:
- 观察蜜蜂在不同资源可用性时期的食行为.
- 量化了用于阻止招募危险资源的抑制性"停止信号"的发生率.
- 评估了采集者对资源的坚持,尽管遇到其他蜜蜂的攻击.
主要成果:

Frequency-dependent Selection
22.2K
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.

Responses to Heat and Cold Stress
13.8K
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.

Adaptations that Reduce Water Loss
26.3K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Energy Budgets
9.7K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Biological Clocks and Seasonal Responses
38.2K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
