title: Daily variation and repeatability of advertisement calls in an austral temperate forest frog under controlled conditions

description: Estimating repeatability allows a first approximation that may indicate a
 potential response to selection of sexual traits. Acoustic sexual signals
 comprise spectral and temporal variables, where the former generally have
 lower intra-individual variation and higher repeatability values. Studies
 of repeatability in anurans have been conducted mainly in natural
 conditions, but the stability of laboratory settings allows extended
 recording intervals, favoring measurement accuracy. We conducted a study
 of variation and repeatability of the calls of males of Batrachyla
 taeniata, a frog from the South American temperate forest to evaluate
 under homogeneous environmental and social conditions: i) the extent of
 variation in acoustic properties of calls within and among days, ii) the
 extent of temporal variation in the repeatability of call properties, and
 iii) differences in repeatability among call variables. Variation of
 acoustic properties differed within and across days of recording, call
 rate generally increased within and throughout days, suggesting
 sensitization processes. Call duration decreased during these time spans,
 yielding constant calling effort. In contrast, the dominant frequency
 decreased within days but increased across days. Overall repeatability
 differs significantly among variables: dominant frequency, call rate and
 call duration having the highest, intermediate and lowest values,
 respectively. The high repeatability of call rate relative to call
 duration contrasts with an opposing general tendency in previous studies
 in anurans. The repeatability of the three variables analyzed increases
 within days and the repeatability of call rate also increases throughout
 days, highlighting the relevance of this variable for individual identity
 over different time ranges. The procedures were in accordance with
 national laws of animal welfare and were approved by the Comité
 institucional de cuidado y uso de animales (CICUA, Protocolo UNI
 21014-MED-UCH). This dataset contains the acoustic variables analyzed in
 the study. Specifically, the file “Data_DF_DUR.csv” includes 5 columns
 corresponding to: ID of individuals, day, block, snout-vent length,
 dominant frequency (Hz), duration (s). The file “Data_nCalls.csv” includes
 4 columns corresponding to: ID of individuals, day, block, snout-vent
 length, number of calls produced within 10 min. In addition, the R script
 including the analyses and figures is provided.
