What chemical substances are released by various species that can influence behaviors, such as mating?

Pheromones are chemical substances secreted by an organism to communicate with others of the same species, often influencing behaviors such as mating, territory establishment, and marking pathways. These airborne chemicals are detected by the vomeronasal organ in many animals, which helps them to identify potential mates or rivals. Pheromones play a crucial role in social and reproductive behaviors within species, leading to specific actions based on their presence.

Neurotransmitters are chemicals that transmit signals across a synapse in the nervous system, affecting neuronal communication but not directly influencing behaviors in the same way pheromones do in species interactions. Hormones are also important, as they are released into the bloodstream and can influence various bodily functions and behaviors, but they operate on a broader physiological level rather than through direct chemical communication among individuals. Cooking extracts are not relevant in this context, as they do not serve a purpose in animal behavior related to mating or interaction. Overall, pheromones are the specific substances recognized for their role in influencing social and reproductive behaviors in animals.
