The impact of parasitic infection on acoustic communication and mate choice in two torrent frogs with nonlinear vocalization

For frogs with linear vocalization, Hamilton and Zuk’s hypothesis indicated that parasites adversely affect male sex characters and parasite infection can result in sexual signals that are less intense or conspicuous than in healthy individuals, which causes females to prefer unparasitized over parasitized males. In order to investigate the effects of parasite infection on vocal characteristics and mate choice in frogs, which can emit nonlinear phenomena calls (NLP). The calls of the two species of torrent male frog, namely the concave-eared torrent frog (Odorrana tormota) and the large odorous frog (Odorrana graminea), were recorded, and several vocal parameters (calling duration, calling rate, average fundamental frequency, NLP duration and NLP content) and parasite intensity were analyzed in detail. The results revealed a negative relationship between calling rate and parasite intensity and a positive relationship between NLP content and parasite intensity. Furthermore, the effects o..., , , # Title: Impact of parasitic infection on mate choice in two torrent frogs with nonlinear vocalization

Our three dataset files are the parasite species contained in the different organs of the two male frogs, the parasite content of the male selected by the female in the sexual selection experiment, and the parameters related to the amplectant male and the non-amplectant male (parasite content, body size, environmental parameters and acoustic parameters).
