Undeniably, acoustic signals are the predominant mode of communication in frogs and
toads. Acoustically active species are found throughout the vast diversity of anuran families …

In 2005, Holy and Guo advanced the idea that male mice produce ultrasonic vocalizations
(USV) with some features similar to courtship songs of songbirds. Since then, studies …

In the search for understanding female sexual decision-making, progress has been made in
uncovering a variety of perceptual biases and most of these concern the animal's sensory …

Since the time of Darwin, biologists have wondered whether birdsong and music may serve
similar purposes or have the same evolutionary precursors. Most attempts to compare song …

Because of its close relationship with the process of evolutionary differentiation, it is
expected that geographic variability in acoustic sexual traits should be greater among than …

Female mate choice behavior is a critical component of sexual selection, yet identifying the
neural basis of this behavior is largely unresolved. Previous studies have implicated sensory …

While the neural circuitry and physiology of the auditory system is well studied among
vertebrates, far less is known about how the auditory system interacts with other neural …

Estradiol plays an important role in mediating changes in female sexual behavior across
reproductive cycles. In the túngara frog [Physalaemus (= Engystomops) pustulosus], the …

To date, there are only few reports of immediate early genes (IEGs) available in insects.
Aiming at identifying a conserved IEG in insects, we characterized an Egr homolog of the …

Geographic variation of traits may represent the first step for evolutionary divergence
potentially leading to speciation. Signals are behavioral traits of particular interest for the …
