Males of some species build nests for reproductive activities but generally do not directly convey information of these constructions to *** the present study,we demonstrate that the calls of the males of the Emei music frog(Babina dauchina) that vocalize from male-built nests carry information of the nest structure and this information can be recognized by ***-nest calls consisted of syllables with energy concentrated at lower frequency ranges and longer syllable durations compared with outside-nest *** the fundamental and center frequencies of the inside-nest call were positively correlated with the area of burrow ***,the syllable durations of were positively correlated with the depth of the *** significant relationships were found between fundamental frequency,center frequency,syllable duration and body mass or body *** than 70% of the females tested chose inside-nest calls when given a choice between outside-and inside-calls played *** percent of the females tested chose outside-calls when using white noise as control sound for antiphonal *** demonstrate that males of this species faithfully advertise nest resources to potential mates by vocal communication,facilitating mate selection by *** results suggest a novel means for studying the tradeoff between selecting body condition and resource quality.
