The Role of Male Vocal Signals During Male-Male Competition and Female Mate Choice in Greater Prairie-Chickens (<i>Tympanuchus cupido</i>)
In many taxa, vocal communication plays an integral role in aggression, territorial defense, and female choice. The acoustic structure of vocalizations is influenced by physical constraints on the vocalizer, suggesting a potential for discrimination among individuals. In the lek-mating Greater …

Diversity of Form, Content, and Function in the Vocal Signals of Adult Male Blue Monkeys (Cercopithecus mitis stuhlmanni): An Evolutionary Approach to Understanding a Signal Repertoire
… virtually every vertebrate taxonomic division, vocal signals play key roles in predator avoidance, reproduction, competition, and mediating social interactions. Understanding signaling systems, and the various selection factors relating to their evolution and maintenance, therefore provides …

The role of social environment in shaping vocal communication systems in wild songbirds
For many taxa, vocal communication is an essential means of navigating continuously changing social and ecological environments. Among passerine birds, vocal signals are critical to survival and play an important role in mate attraction, territory defense, and predator avoidance. In my …

Cultural evolution in Rufous-and-white Wrens (Thryophilus rufalbus): Insights from acoustic and genetic analyses
Acoustic signals play an important role in the evolutionary process. Studying variation in acoustic signals and the evolutionary forces that act on acoustic evolution will help to clarify the role that acoustic divergence plays during speciation. The acoustic signals of birds have been well …

Demography and Behavior of Western Sandpipers (Calidris mauri) Breeding on the Yukon-Kuskokwim River Delta, Alaska
… Through experimental playback of adult vocalizations to chicks in the field, I demonstrated: (1) chicks respond to the alarm call by vocalizing relatively less often and moving away from the signal source, (2) chicks respond to the gather call by vocalizing relatively more often and …
