“…Nonetheless, females may also be larger than males due to higher growth rates and delayed reproduction (Miaud et al 1999, Valdez & Maneyro 2016. Although larger size usually benefits males competing for females (Davies & Halliday 1978, Vági & Hettyey 2016, being smaller can also be advantageous for males by resulting in higher mobilization capacity and agility (Hudson et al 2020, Zhang et al 2020a.…”

Sexual dimorphism, i.e., differences in morphology between sexes of a species caused by intersexual differences in the strength or direction of sexual or natural selection, is prevalent throughout the animal kingdom. Contrary to differences in body size, little is known about sexual shape dimorphism in anurans. Here we investigated intersexual shape differences in Bufo verrucosissimus (Pallas, 1814) by taking 27 linear measurements to characterize body morphology of 23 males and 23 females. Relative to their overall body size, males had longer limbs and larger eyes, while females displayed larger parotoid glands and had wider heads. We speculate that these intersexual differences may have arisen due to differences in natural and sexual selection regimes acting on males and females, especially during foraging, mate searching, or intrasexual competition.

“…Similar to that of a sympatric species, Odorrana tormota , the calls of O. graminea consist of ultrasonic and NLP components (Shen et al, 2011 ; Zhang et al, 2021 ). In O. tormota , smaller males with higher call frequencies had greater mating success than larger rivals, as their calls were more conspicuous in the species’ habitat with intense but predominantly low‐frequency stream noise (Zhang et al, 2020 ). Whether the mode of mate choice in O. graminea is similar to that in O. tormota remains unknown.…”

In anurans, the complexity of courtship calls may affect female mate choice. The current study suggests that nonlinear phenomena (NLP) components can contribute to increasing complexity in courtship calls and attracting female attention. The results of a recent study showed that calls of large odorous frog ( Odorrana graminea ) contained NLP components. However, whether the nonlinear components of courtship calls in O. graminea improve male attractiveness remains unknown. We hypothesized that female O. graminea would prefer males producing calls with a higher proportion of NLP components (P‐NLP‐C). To test this hypothesis, we recorded the advertisement calls of 28 males and confirmed that the P‐NLP‐C was significantly positively related to body size. We also measured the body size of natural amplectant males and non‐amplectant males in the field and found that amplectant males had larger body sizes than non‐amplectant males, and the results of two‐choice amplexus experiments similarly revealed a female preference for males with larger body sizes. Additionally, phonotaxis experiments also revealed that females preferred male calls with a high P‐NLP‐C. The results suggest that a higher P‐NLP‐C in calls can enhance male attractiveness, and the P‐NLP‐C may provide key information about male body conditions for female O. graminea . Our study provides a new insight for better understanding the role of NLP in anuran mate selection.

“…High-quality or ‘attractive’ calls by males are often those which are energetically more costly, correlating with individuals’ health, fitness, locality, parental care and/or increased egg fertilisation (Ryan et al 1992 ; Prestwich 1994 ; Morrison et al 2001 ; Gerhardt and Huber 2002 ; Felton et al 2006 ; Jacobs et al 2017 ; Kaiser et al 2018 ). Exact call characteristics that are considered attractive such as frequency, call rate and tenure (number of nights spent at the chorus) differ between species (Morrison et al 2001 ; Zhang et al 2020 ). Thus, the detection and processing of conspecific calls is a crucial component of anuran mating behaviour.…”

Limited effects of traffic noise on behavioural responses to conspecific mating calls in the eastern sedge frog Litoria fallax

Anthropogenic noise is a pervasive environmental feature across both urban and non-urban habitats and presents a novel challenge especially for acoustically communicating species. While it is known that some species adjust acoustic signals to communicate more effectively in noisy habitats, we know very little about how the receivers of these signals might be impacted by anthropogenic noise. Here, we investigated female and male Litoria fallax frogs’ ability to distinguish between high- and low-quality acoustic signals during the presence of background traffic noise and without. We performed a controlled behavioural experiment whereby frogs were presented with simultaneously broadcasted attractive and unattractive calls from opposing directions, once with background traffic noise and once without. We found that females in particular chose the unattractive call significantly more often (and males significantly less often) when noise was being broadcast. This indicates that anthropogenic noise potentially affects receiver responses to acoustic signals, even when calls are not acoustically masked, with potential consequences for maladaptive mating behaviours and population outcomes.
