The relative effectiveness of signaling systems: relying on external items reduces signaling accuracy while leks increase accuracy.

Multiple evolutionary phenomena require individual animals to assess conspecifics based on behaviors, morphology, or both. Both behavior and morphology can provide information about individuals and are often used as signals to convey information about quality, motivation, or energetic output. In cer...
