摘要: The reactions of a territorial male lizard (Anolis aeneus) to an intruder were filmed and analyzed. Five displays given the intruder: Fanbob, Multibob, Jerkbob, Gorged-throat Fan. Fanbob consists species-specific signature bob dewlap extension is normal display as challenge intruders. another pattern, occurs when degree anxiety present. It closely resembles Courtship Bob, so in effect giving appeasement while courting female. Jerkbob used introductory preceding during advertisement. threat display, Fan may be instead inhibitory factors prevent from being expressed. was analyzed test whether it fulfills criteria Fixed Action Pattern. cadence individual-specific stereotyped, but other components varied greatly. Among these presence absence movements (related distance), sideflattening resident aggressiveness), height head display. Height extension, necessary integral independently, correlated with different sets stimulus response variables. thus shown fit none fixed action pattern.
