You sound like my Mr. Right: female frogs choose size-assortative mates through acoustic features

Key Points

• Female frogs show a preference for mating based on the acoustic features of potential mates, leading to size-assortative mating.
• The analysis indicates that vocalizations influence female choice, aligning with the size of the frogs, which may affect reproductive success.
• This observational analysis investigates vocalization patterns in various frog species to understand mating preferences through acoustic features.
• Findings suggest that the role of sound in mate selection can promote reproductive isolation, reinforcing evolutionary divergence.
