Summary
Male frogs adjust their vocal sequences and repertoire size when facing rivals. Network analysis reveals decreased call network connectivity in competitive contexts, offering insights into animal communication.
Area of Science:
- Animal Behavior
- Bioacoustics
- Network Science
Background:
- Vocalizations are crucial for anuran survival and reproduction, with males altering calls based on ecological context.
- While vocal sequences convey context-dependent information in many species, studies on anuran vocal sequence variation are limited.
Purpose of the Study:
- To investigate context-dependent vocal repertoire, sequence, and call network structure in serrate-legged small treefrogs (Kurixalus odontotarsus).
- To apply network analysis to understand vocal sequence patterns in anurans.
Main Methods:
- Employed conventional methods alongside network analysis to study vocalizations.
- Analyzed vocal sequences and call network properties during competitive (rival presence) and non-competitive contexts.
Main Results:
- Male frogs modified vocal sequences by switching call types and increasing repertoire size when a rival was present.
- Call network analysis showed decreased mean degree, closeness, and betweenness, indicating lower connectivity during competition.
- Increased one-way motifs and average path length further supported reduced network connectivity in competitive contexts.
Conclusions:
- Male Kurixalus odontotarsus alter vocal sequences and network structure in response to social competition.
- Network analysis provides a valuable framework for studying vocal sequences in anurans, with implications for understanding communication evolution.
