概括
这项研究表明,狗的品种和对训练的反应能力在自然检测任务中显著影响嗅觉性能. 然而,广泛的培训可能会矛盾地减缓搜索时间.
科学领域:
- 狗的伦理学 狗的伦理学
- 动物的嗅觉 动物的嗅觉
- 行为遗传学 行为遗传学
背景情况:
- 以前的狗嗅觉研究通常依赖于训练有素的狗或特定的个体.
- 自然检测任务 (NDT) 提供了一种新的方法,可以在没有事先培训的情况下评估嗅觉表现.
研究的目的:
- 通过使用NDT在大量多样化的狗群体中研究影响嗅觉表现的因素.
- 为了确定品种,个性特征和训练水平对自然检测成功的影响.
主要方法:
- 使用自然检测任务 (NDT) 评估了484只狗.
- 分析了品种的影响,功能性品种群,人格分数 (对训练的反应,活动/兴奋能力,多动症) 和训练水平.
- 与业主的奖励风格相关联的性能.
主要成果:
- 嗅觉的成功程度因品种而异,边境犬的表现优于用于狩猎/嗅觉任务的品种.
- 比格尔比其他几种品种的搜索时间更快.
- 对培训成绩的更高反应与更大的成功相关,而高级培训水平与更慢的搜索有关.
- 品种组不是重要的预测因素;品种特有的特征更有影响力.

01:25Olfaction
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.

01:20Physiology 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.
