Vocalizations of anuran amphibians have received much attention in studies of behavioral
ecology and physiology, but also provide informative characters for identifying and …

Acoustic signals are the most important communication mechanism for many anuran
species. However, acoustic parameters can be influenced by several factors (eg, body size …

Many animals rely on vocal communication for mating advertisement, territorial displays, and
warning calls. Advertisement calls are species‐specific, serve as a premating isolation …

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 …

Acoustic communication is vital to the survival and fitness of many vertebrates. While
successful communication is reliant on acoustic signals reaching an intended receiver and …

Studies of the variability of signals at different levels are important to resolve issues related
to the evolution of a species' recognition system. We analysed the variation within males …

Background We examined differences in reproductive activities and intraspecific variations
in advertisement calls of Duttaphrynus melanostictus (Schneider, 1799) that lives in a …

We investigated the influence of air and water temperature, relative humidity, morphological
characteristics and distance between males on call parameters of Physalaemus cuvieri. We …

Geographic variation in acoustic characteristics of anuran advertisement calls could be an
important indicator of species divergence due to its importance for species recognition. In …

Acoustic signals are employed to support the correct designation of species and enables the
discrimination between individuals. We analyzed both intra and interindividual variability of …
