Anuran amphibians use vocal signals as one of the most important forms of communication, emitted in various social contexts. Anuran species present specific vocalizations, however, acoustic parameters can vary by several factors. Thus, the aim of this study was to investigate the influence of environmental, morphological and temporal factors on vocalizations of Dendropsophus minutus, through two approaches. We analyzed the acoustic variability of D. minutus along reproductive seasons, and afterwards, the effect of temperature on acoustic and body parameters of D. minutus. The analyzes were based on nine breeding seasons, carried out in individuals in a temporary pond in the municipality of Piracanjuba, state of Goiás, Brazil. We considered a mean of five advertisement calls per individual, being spectral (dominant and fundamental frequency) and temporal properties (call duration, pulse duration, number of pulses and call repetition rate) quantified. Air temperature data at the time of recording, snout-vent length and mass of individuals were also measured.
