Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The present study describes the acoustic structure and associated behavioural contexts of vocalizations of Asian elephant calves. Three hundred twenty-seven vocalizations of six calves aged between 6 and 27 months were recorded at the Emmen and the Cologne zoo. Based on temporal and structural characteristics including nonlinear phenomena, we structurally distinguished four call types, the rumble, the roar, the chirp and the trumpet. Most vocalizations were uttered during all forms of play behaviour, with chirps and trumpets dominating here. Rumbles were mainly recorded in combination with roars; the latter were highly chaotic in structure and associated with higher arousal contexts (e.g., being separated from the mother). These first insights into the vocal behaviour of Asian elephant calves reveal that calf vocalizations clearly differ in acoustic structure and application from those of adults and older juveniles. This highlights the importance of investigating the vocal ontogeny of elephants as well as other species having a long adolescence and developmental period.
