How do pheromones affect animal behavior?

Pheromones are crucial chemical signals that can significantly influence the behavior and physiology of animals. Various species release pheromones to convey important information regarding territory, mating readiness, social interactions, or alarm signals. When another animal detects these chemical substances, it can trigger specific behavioral responses or physiological changes. For example, in many species, the presence of a pheromone can stimulate mating behavior or establish dominance hierarchies.

In contrast to visual signals, which rely on sight, pheromones operate through the sense of smell and can be effective across distances and in low-light conditions, making them particularly important for communication in nocturnal or social species. Additionally, pheromones are not limited to mating seasons; they can be relevant in various social contexts throughout an animal's life. Overall, pheromones play a critical role in maintaining social structures and survival in animal populations.
