| Popis: | In a single population of a livebearing fish, the green swordtail (Xiphophorus hellerii), a trait considered a static badge of status in males of other populations, the color of a stripe covering the lateral line, has been found to be dynamic relative to their social environment, potentially rendering this signal meaningless. Males change the color expression of their lateral stripe dynamically based on social environment. We investigated if males (n = 26) respond to visual and chemical information about other males with a color change and aggressive behavior. We found that visual information is indeed causing color change, whereas chemical information is less effective. Aggressive responses and frequency of response did not change significantly with the mode of communication. We also studied female preferences for color, but found no significant preference (n = 32). Our results lead to questions as to how interpopulation variation can affect preferences and how dynamic signaling—in this case signal transmission presumably dependent on sex and/or status—influences the behavioral interactions we might expect between X. hellerii in the field. |
