Coding Strategies in Vertebrate Acoustic Communication
The Mathematical Theory of Communication predicts how the amount of information of a signal is transmitted from an emitter to a receiver after propagation through the environment, which goes far beyond the technical aspects of human communication and was rapidly adopted by other fields.
Coding of Static Information in Terrestrial Mammal Vocal Signals
The body of research reviewed in this chapter illustrates how combining observational, acoustics, experimental, and comparative approaches enables researchers to draw general conclusions about the selection pressures driving the evolution of vocal production and perception in mammals.
Audiograms of howling monkeys: are extreme loud calls the result of runaway selection?
It is suggested that the extraordinary loudness of male howling is an indirect (runaway) result of positive feedback between the selective pressures of hearing infant distress calls and deterring infanticide.
Reduced geographic variation in roars in different habitats rejects the acoustic adaptation hypothesis in the black‐and‐gold howler monkey ( Alouatta caraya )
The combination of high amplitude and low peak frequency of roars, coupled to small home range size and extensive overlap between neighboring groups, allows roars to keep their communication value across habitats without need of specific environmental tuning.

Evidence of biphonation and source–filter interactions in the bugles of male North American wapiti (Cervus canadensis)
It is speculated that male wapiti have evolved such a dual-source phonation to advertise body size at close range (with a relatively low-frequency F0 providing a dense spectrum to highlight size-related information contained in formants) while simultaneously advertising their presence over greater distances using the very high-amplitude G0 whistle component.
Vertebrate Bioacoustics: Prospects and Open Problems
Most known vocal peculiarities including air sacs, vocal fold modifications, the syringeal bulla present in most ducks, or the elongated trachea seen in many bird species are covered.
Vertebrate Sound Production and Acoustic Communication
This chapter provides a historical overview of the origins of two critical bodies of theory, the source-fi lter theory of vocal production and the myo-elastic aerodynamic theory of the voice source, and details how these theories were gradually applied to nonhuman animal vocalizations.

The Meaning of Evolution
VI. Zoology of Mycetes Seniculus
The Howlers belong to the American group of broad-nosed, prehensile-tailed monkeys, which are much lower in structure than the man-like apes, and are said to be developed to a great extent in the male.
