The acoustic adaptation hypothesis predicts that sound communication signals have an optimal relationship with animals' native environments. However, species sharing a habitat produce signals stratified in the spectral ...

A variety of animals that communicate by sound emit signals from sites favoring their propagation, thereby increasing the range over which these sounds convey information. A different significance of calling sites has been ...

Localization of a sound source is important for animals in mating contexts: females generally orient towards signalling males, and males can estimate the position and quality of potential rivals. In anurans, the effect of ...

The variability of the advertisement calls of males from two Chilean populations of the leptodactylid frogs, Eupsophus calcaratus and E. roseus was studied and their calling behaviour further defined. Characteristic audio ...

The effect of burrow acoustics on the reception of sounds by a leptodactylid frog, Eupsophus emiliopugini, from Southern Chile was investigated. Burrows occupied by E. emiliopugini males amplified vocalizations produced ...

The description of a new species of Eupsophus, from Los Queules National Reserve (35° 59' S, 72° 41'W) adds a new endemic taxon to the fauna of telmatobines (Amphibia, Leptodactylidae) of Chile, and extends the geographical ...

Thresholds for evoked advertisement calling for 18 males were measured in a temperate forest in southern Chile, in order to relate this behavior to the intensities of neighbors' calls that males of this species encounter ...
