“…Still, B . leptolineata is known to change call rate in response to the calls of invasive frogs, even when their calls present little spectral overlap, as well as in response to continuous white noise [ 31 ]. In sum, these results point out that adjustments in call rate are likely to be stimulus-specific, and that the triggers for that adjustment are yet to be fully explored.…”

“…One should expect a close relationship between the degree of frequency overlap between calls and noise and the type or intensity of call modification. Indeed, species calling at frequencies within the noise spectral range will tend to be more affected [ 31 ], and therefore are more likely to have to adjust their calls towards a reduction in temporal and spectral overlap. Changes in call pattern may also be directly related to the intensity of the noise [ 14 , 32 , 33 ], as background noise can limit the distance over which an individual can perceive acoustic signals [ 3 ].…”

Anthropogenic disturbance has been pointed to as one of the major causes of the world´s biodiversity crisis. Among them, noise pollution is a potential underestimated threat, projected to increase in the next decades accompanying urban expansion. Rising levels of noise pollution may result in negative impacts on species highly dependent on acoustic communication. Amphibians have long served as model organisms for investigating animal acoustic communication because their reproduction depends on transmitting and receiving acoustic signals. A few studies have investigated the effects of anthropogenic noise on anurans, but there is still limited knowledge on how it affects them. In this study, we test the effect of two intensities of traffic noise on calling males of two Neotropical treefrogs species. We expect to record more changes in call parameters, to avoid masking effect, at higher intensity noise treatments, and in the species with higher call/noise frequency overlap. We performed a set of field playback experiments exposing male frogs to road noise at two different intensities (65dB and 75dB). Focal species are Boana bischoffi (high call/noise frequency overlap) and B. leptolineata (low call/noise frequency overlap). Both species changed acoustic parameters during or after the exposure to traffic noise. Advertisement call rate of B. bischoffi decreased during road noise, and dominant frequency decreased over time. Call length of B. leptolineata increased or decreased, depending on the order of noise intensity. We also observed spatial displacement in both species, which moved away from the noise source. Our results provide evidence that traffic noise affects anuran calling behavior, and noise intensity is an important factor affecting how species respond.

“…Invasive species, for instance, can disturb sexual communication in native species by masking or altering their signals. For instance, the calls of the invasive American bullfrog ( Lithobates catesbeianus ) cause native Brazilian frogs to modify their calls (Both & Grant, ; Medeiros et al ., ). Similarly, the invasive cane toad ( Rhinella marina ) causes a native Australian frog ( Limnodynastes convexiusculus ) to reduce its calling (Bleach et al ., ).…”

Human activities by altering environmental conditions are influencing the mate choice of animals. This is by impacts on: (i) the production and expression of traits evaluated by mate choosers; (ii) the transmission of information about potential mates to choosers; (iii) the reception and processing of the information by choosers; and (iv) the final mate choice. Here, I first discuss how these four stages of the mate‐choice process can be altered by environmental change, and how these alterations, in turn, can influence individuals, populations, and communities. Much evidence exists for human‐induced environmental changes influencing mate choice, but the consequences for the fitness of courters and choosers are less well known, and even less is known about the impact on population dynamics, species interactions and community composition. More evidence exists for altered mate‐choice systems influencing interspecific matings and thereby community composition and biodiversity. I then consider whether plastic adjustments and evolutionary changes can rescue adaptive mate‐choice systems, and reflect on the possibility of non‐adaptive mate‐choice systems becoming less maladaptive under environmental change. Much evidence exists for plastic adjustments of mate‐choice systems, but whether these are adaptive is seldom known, as is the contribution of genetic changes. Finally, I contemplate the possibility of mate‐choice systems rescuing populations from decline in changing environments. I explain how this is context dependent with both positive and negative outcomes possible. In summary, while much evidence exists for human‐induced environmental changes influencing mate‐choice systems, less is known about the consequences for ecological and evolutionary processes. Considering the importance that mate choice plays in determining individual fitness and population viability, the effects of environmental change on mate‐choice systems should be considered in studies on the ecological and evolutionary consequences of human disturbances to habitats.

“…This suggests that the frequency band of L. larvaepartus can mask the frequency band of L. modestus. Based on the acoustic niches, these two frogs cannot live together in the same habitat, because the overlap in the acoustic niches disturbs the comfort zone of the other frog acoustic niches, which calls that has wide-frequency band and broad-energy spectrum can interfere the acoustic niches of other frogs species that has calls with a narrow frequency spectrum [21]. Harmonization of acoustics with minimal overlapping of frequency bands is a requirement to occupy the same microhabitat of the frog species group [22].…”

The advertisement call of Limnonectes larvaepartus is unique among frogs of the genus Limnonectes which have a true acoustic organ. The calls of three adult males L. larvaepartus were recorded at the foothill of Hutadelita Mountain (N 000 48’ 48.3” E 1220 23’ 00.8”; 396 m asl), Nantu Wildlife Sanctuary, Gorontalo, northern Sulawesi by using an Olympus LS-11 recorder with built-in microphones. Air temperature during recording was around 26°C. Adobe Audition 3.0 software was used to visualize and analyze the calls. The advertisement calls consist of 1-6 pulses, though only one pulse is usually produced. The wave structure of the call of L. laervaepartus is unusual because it is characterized by a short series of pulses that form a pulse train. Each pulse from the beginning of the call until the middle of the call has its own frequency spectrum, whereas the pulse train during the second half of the call becomes tightly compressed and forms one frequency spectrum. Calls of L. larvaepartus do not have a dominant frequency. Minimum frequencies decrease gradually from the beginning to the end of the pulse train; however, the maximum frequency rises gradually. Ascending frequency characters in one pulse also occur in the energy spectrum and bandwidth of frequency. The lowest minimum frequency at the end of pulse train is ~165 Hz; while the highest maximum frequency is also located at the end of the pulse train and is ~6860 Hz. The short pulses call of L. larvaepertus is similar to that of L. hasceanus, although the two species are not close relatives; in L. larvaepartus, the pulse only consists of one period, whereas in L. haschenus it consists of two periods. Considering acoustic adaptation, call of L. larvaepartus has similar frequency spectrum with call of L. modestus, we assume that they would not call at the same time and at the same localities because of their similar acoustic niches.
