← Nature & AnimalsWhich vocalization feature correlates with bat colony size?
A)Increased call frequency variation✓
B)Decreased temporal pattern entropy
C)Amplified peak decibel intensity
D)Reduced minimum call spectral bandwidth
💡 Explanation
Increased call frequency variation arises because signature call divergence helps maintain individual recognition within larger groups; therefore, it prevents the bat colony from fragmented social structure, rather than increased signal intensity/bandwidth.
