Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Marine mammal vocalizations are categorized into distinct types, such as whistles, clicks, and pulses, which occupy specific frequency and acoustic niches.

The analysis

The retrieved papers provide strong empirical evidence that marine mammals produce diverse vocalizations (such as echolocation clicks, whistles, burst pulses, and specific seal calls) that exhibit distinguishable acoustic features and occupy distinct frequency niches within their repertoires.
