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

Arginine vasotocin (AVT) is the non-mammalian homolog of arginine vasopressin (AVP)
and, like vasopressin, serves as an important modulator of social behavior in addition to its …

Zhao et al. recently reported results which, they claim, suggest that sexual selection
produces the multimodal displays seen in little torrent frogs (Amolops torrentis) by co-opting …

Natural history specimens are a widely used and valuable resource for conservation,
ecology, and evolutionary biology. One might assume that these collections are …

A hallmark of sexual selection is the evolution of elaborate male sexual signals. Yet, how the
physiology of an animal changes to support a new or modified signal is a question that has …

The use of acoustic signals is a common characteristic of most anuran species to mediate
intraspecific communication. Besides many social purposes, one of the main functions of …

Cascades and fast-flowing streams impose severe restrictions on acoustic communication,
with loud broadband background noise hampering signal detection and recognition. In this …

In this study a new species of Pristimantis (Anura: Craugastoridae) of the P. conspicillatus
species group is described. Pristimantis latro sp. n. is known only from the municipalities of …

Frogs of the genus Thoropa comprise six endemic Brazilian species on the Eastern side of
the country. Little is known about their natural history, especially about their acoustic …

Vocalisations play a vital role in animal communication, as they are involved in many
biological functions such as mate selection, individual recognition and care of young …
