概括

捕食者保护可口的模仿者只有当他们同时发生与无血型模型. 如果没有模型,学会避免有毒模型并不能保护模仿者,这凸显了当前捕食者信息在模仿动态中的重要性.

科学领域:

生态生态学生态生态学
进化生物学进化生物学
行为生态学行为生态学

背景情况:

贝蒂斯模仿涉及类似于有毒物种的可口物种,以阻止捕食者.
维持模仿的机制,特别是捕食者学习和猎物现象学,尚未完全理解.
之前的观察表明,模仿系统中时间同步和模型首次出现非常重要.

研究的目的:

用实验来测试捕食者寻食物的决定是否推动了模仿复合体中的猎物现象学的进化.
调查时间同步和模型首次出现对模仿保护的重要性.
为了确定是否学会了避开 aposematic 模型的好处,Bateesian 模仿.

主要方法:

使用了模型物种*Battus philenor*和模仿物种*Limenitis arthemis astyanax*的表型准确的蝶复制品.
在四种不同的现象学条件下测量了复制品的掠食率.
操纵时间同步和模型首次出现以模拟自然的捕食者-猎物相互作用.

主要成果:

即使在短时间内,异步模型的首次出现也没有增加模仿保护.
模仿者仅在与模型的时间同步条件下才能获得保护.
捕食者对模型的避开在模型缺席的情况下不会随着时间的推移而持续.

结论:

在贝蒂斯模仿中,时间同步对于捕食者与猎物的相互作用至关重要.
捕食者依赖于当前的环境线索 (即模型和模仿者的同时存在),而不是从过去的遭遇中学习避免.
这些发现表明,捕食者寻找食物的决定,由即时信息驱动,塑造模仿复合体的现象进化.

Nonconscious Mimicry

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

What is a Species?

Communication

Communication

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

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.

Mate Choice

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
