概括

猫头 (Aotus nancymaae) 主要使用嗅觉线索在夜间检测昆虫,转换到视觉线索进行更密切的检查. 这种感官策略有助于它们夜间捕食昆虫.

科学领域:

灵长类动物学灵长类动物学
感官生态学感官生态学
行为生物学行为生物学

背景情况:

夜行哺乳动物拥有专门的感官适应性,以在夜间寻找食物.
猫头 (Aotus spp.) 是一个类型. 它们是夜间活动的灵长类动物,在低光下擅长捕食昆虫.
它们利用声学和化学信号进行通信,并通过嗅觉来检测水果.

研究的目的:

为了研究特定的感官线索 (听觉,嗅觉,视觉) Aotus nancymaae用于昆虫食.
为了比较对个人和综合感官线索的行为反应.

主要方法:

23只被囚禁的猫头参加了含有昆虫线索的感觉盒的试验.
每种感官模式 (听觉,嗅觉,视觉) 都被单独和多模式测试.
一般化的线性混合模型分析了对不同线索的行为反应.

主要成果:

与控制盒相比,猫头对带有昆虫线索的盒子表现出更大的兴趣.
嗅觉线索,单独或组合,引起了显著的食行为 (打喷,).
视觉线索在接近时被更多地吸引,这表明了一种连续的感官策略.

结论:

Aotus nancymaae在很大程度上依赖于嗅觉来远距离检测猎物,以及用于最终猎物定位的视觉线索.
它们的感觉食策略不同于夜间的链状虫,可能是由于它们夜间活动的次要演变.
雄性猫头可能比雌性更少的新恐惧症,更快地接近感官刺激.

Optimal Foraging

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

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.

Olfaction

Olfaction

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Osmoregulation in Insects

Osmoregulation in Insects

Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area.

Physiology of Smell and Olfactory Pathway

Physiology of Smell and Olfactory Pathway

Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
The olfactory...

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.
