Highlights•Rodents exhibit extreme variation in acoustic signal structure.•Intraspecific
acoustic variation is often overlooked.•Acoustic variation is associated with ontogenic, social …

Like many adaptive behaviors, acoustic communication often requires rapid modification of
motor output in response to sensory cues. However, little is known about the sensorimotor …

Highlights•Rodents display diverse social behaviors.•Many social behaviors are supported
by acoustic communication.•Rodent studies are providing insights into the neural circuits …

Neocortical activity is thought to mediate voluntary control over vocal production, but the
underlying neural mechanisms remain unclear. In a highly vocal rodent, the male Alston's …

mice (genus Scotinomys) are small (~ 12–15g), diurnal, insectivorous, highly vocal rodents
belonging to the family Cricetidae. They live in the montane cloud forests and pastures of …

Highlights•I explore two factors that can limit sexual trait elaboration: costs and constraints.•I
discuss operational strategies for identifying constraints on sexual traits.•I propose that costs …

Highlights•Some honey bee nurses altered offspring care when the hive was
threatened.•Nurses from highly aggressive hives decreased larval care following alarm …

Vocalizations are often elaborate, rhythmically structured behaviors. Vocal motor patterns
require close coordination of neural circuits governing the muscles of the larynx, jaw, and …

Highlights•We examine how energy balance/social context affect display effort in singing
mice.•We injected mice with leptin or saline before or after exposure to conspecific …

Because of their roles in courtship and intrasexual competition, sexual displays are often
sexually dimorphic, but we know little about the mechanisms that produce such dimorphism …
