Document Summary

Chemical ecology: the study of structure, origin and function of naturally occurring chemicals that mediate interaction between individuals of the same species and between individuals of different species. Semiochemical: signaling chemical released into environment (between individuals of the same & different species) Primer pheromone: pheromones that alter or prime the receiver"s physiology for some event, such as bringing about sexual maturity in preparation for mating. Releaser pheromone: compounds that cause or release" an immediate behavioural response in the receiver. Chemoreception: the detection of chemical compounds of the environment. Volatility: a property referring to the vapour pressure of a chemical - that is, the affinity the chemical has for the gaseous phase at ecologically relevant temperatures. Stability: in the context of pheromones, refers to the reactivity of a chemical. Pheromones which do not tend to react or break down are referred to as stable. Stable pheromone signals can be long-lasting or act over long distances.
