The acoustic adaptation hypothesis finds only modest, inconsistent empirical support

Evidence

Reviews on the acoustic adaptation hypothesis have been proposed by Ey and Fischer (2009) and a meta-analysis was presented by Boncoraglio and Saino (2007), but despite these attempts a clear discriminatory prospect does not emerge between species, and rules and exceptions persist, diminishing the explicative capacity of this hypothesis. It seems that this theory does not explain the communication constraint everywhere. Although the AAH has been tested in 121 species of Australian birds from 41 families by Blumstein and Turner (2005), only a modest support for the hypothesis was found. — Almo Farina, Soundscape Ecology, 460

• DEEPTHINKING: A load-bearing caveat for the whole book’s method: the elegant AAH framing (habitat shapes song) is only weakly supported at scale — a reminder that acoustic patterns are multiply determined, relevant whenever the soundscape-backbone framework is applied.
