Mostrar más [+] Menos [-]Home field advantage is an evolutionarily stable strategy in which the convention of “resident will attack and intruder will flee,” is upheld in a population. The Rock Bass, Ambloplites rupestris is a territorial member of the centrarchid family. When intruders are introduced into the territory of a resident bass, the resident bass will show agonistic behaviors towards the intruder, and the intruder will flee. This paper focuses on determining whether there is a pheromone or chemical released into the water by a resident bass to label itself as the ‘owner’ of a territory. Our experiment found no indication of such a hormone which indicates that the home field advantage convention followed by the rock bass is established by environmental cues other than pheromones released into the water.
