ABSTRACT The Acoustic Adaptation Hypothesis (AAH) posits that animal acoustic signals
used in long-range communication should be adapted to transmit well within the habitats in …

It has been 25 years since the formalization of the Sensory Drive hypothesis was published
in the American Naturalist (1992). Since then, there has been an explosion of research …

Many species use acoustic signals to attract mates, and such signals can be degraded by
anthropogenic noise. Anuran abundance has been shown to be negatively correlated with …

Habitat characterisation is a pivotal step of any animal ecology study. The choice of
variables used to describe habitats is crucial and need to be relevant to the ecology and …

In many animals, males display colorful ornaments to females during courtship, the
effectiveness of which depends on the ambient lighting environment. While a variety of …

Although acoustic signals are important for communication in many taxa, signal propagation
is affected by environmental properties. Strong environmental constraints should drive call …

Animal communication occurs in environments that affect the properties of signals as they
propagate from senders to receivers. We studied the geographic variation of the …

It has been hypothesized that the physical properties of the environment exert selection
pressure on long-range acoustic communication signals to match the local habitat by …

To evaluate the effects of calling site on call degradation, we broadcast synthetic
advertisement calls of male gray treefrogs through forest, over open terrain, and across pond …

Long-range acoustic signals are subject to a variety of evolutionary pressures, such as
sexual selection, species recognition, body-size constraints, physiological constraints, and …
