AbstractWe address the issue of whether call alternation is a mechanism for diminishing call overlap between male midwife toads who are competing acoustically. Additionally, we study the effect of call overlap on the calling behavior of males and on female preferences. In both species, naturally interacting males emitted calls that did not overlap less than expected when males called randomly. Interactive playback calls showed that males increase their calling rate when responded to by a non-overlapping call, and that they do not increase their calling rate when responded to by calls that overlap with their own calls. In phonotaxis tests, females discriminated against duets of males that overlapped their calls. Furthermore, when calling males overlapped the males' calls, females did not discriminate between the male who was leading a calling duet and the follower. We conclude, therefore, that call overlap plays an important role in communication, since overlapping calls are less attractive to females. However, timing of male calling interactions does not diminish the overlap between calls.

Nyctimantis rugiceps Boulenger, 1882 (Fig. 1A) is a Neotropical treefrog (Duellman & Trueb 1976; Faivovich et al. 2005) known only from disjunct localities in Amazonian Colombia, Ecuador, and Peru (Pérez-Villota et al. 2009). This species has the skin of the skull co-ossified and reproduces—including calling behavior, egg deposition and tadpole development—in water-filled tree or bamboo cavities (Duellman & Trueb 1976; Duellman 1978). Given its secretive behavior, this is a poorly known species and, as noted by Duellman (1978: 169), “the major clue to the life history of Nyctimantis is the calling behavior of the males”. Unfortunately, the only quantitative description of the advertisement call of N. rugiceps is a brief passage in Duellman (1978) based on four specimens from Santa Cecilia, Ecuador, where important variables are missing (e.g., call duration). More importantly, graphs illustrating the waveform and spectrogram are missing. Considering these limitations and the importance of advertisement calls to the study of anurans (Köhler et al. 2017), we provide a quantitative description using a call recording obtained in Leticia, Amazonas, Colombia.

The field of behavioral ecology has recently been reinvigorated by the addition of the notion of behavioral syndromes (a.k.a. animal personality). Behavioral syndromes imply the existence of individual variation in behavioral expression that is consistent across distinct functional contexts (e.g. foraging, mating, anti-predator). The syndromes paradigm suggests that the behavioral phenotype is best viewed as an integrated phenomenon wherein any given behavior can only be fully understood by studying selection pressures in all contexts. Here we report on a pilot study on behavioral syndromes in the Sagebrush cricket (Cyphoderrris strepitans), an acoustic Orthopteran insect that inhabits high altitude sagebrush meadows of Grand Teton National Park. The results of our preliminary analysis suggest very little consistent repeatability in the mating behavior of C. strepitans. In addition, we make note of the synergistic collaboration in our group between faculty researchers and graduate, undergraduate and high school research collaborators.

Anuran advertisement calls are life history traits associated with sexual selection and reproduction, and they play an important role in premating isolation mechanisms between species. Comparative bioacoustical analyses of these calls can be useful for taxonomic purposes. Phylogenetic relationships within the genera Pseudis are controversial, especially those related to P. platensis, which is often considered a full species or a subspecies within P. paradoxa. The advertisement call of P. platensis has not been described in detail; therefore, call comparisons of these two conspecifics have not been possible. In this study, we describe the advertisement call and diel activity pattern of P. platensis in the Brazilian Pantanal and compare the calls of P. platensis and P. paradoxa to elucidate whether acoustical parameters may help resolve the present uncertain taxonomic treatment. The advertisement call of P. platensis lasted 0.21 ± 0.01 s and consisted of a short series of 8.05 ± 0.69 distinct pulses (9.34 ± 2.94 ms of pulse duration). The vocal activity of the species was largely restricted to a few hours after dusk (7 – 11 p.m.), which is inconsistent with the diurnal and nocturnal calling behavior described for other Pseudis congeners. The advertisement calls of P. platensis and P. paradoxa were similar in note duration, number of pulses per note and dominant frequency. The geographic variation of calls within species was similar to that found among species. This bioacoustical comparison does not provide new insights into whether P. platensis should be considered a distinct species.

Abstract Acoustic interference can impede effective communication that is important for survival and reproduction of animals. In response to acoustic interference, some animals can improve signalling efficacy by altering the structure of their signals. In this study, we played artificial noise to 46 male spring peepers Pseudacris crucifer, on their breeding grounds, and tested whether the noise affected the duration, call rate, and peak frequency of their advertisement calls. We used two experimental noise treatments that masked either the high- or low-frequency components of an average advertisement call; this allowed us to evaluate whether frogs adaptively shift the peak frequency of their calls away from both types of interference. Our playback treatments caused spring peepers to produce shorter calls, and the high-frequency noise treatment caused them to lower the frequency of their calls immediately after the noise ceased. Call rate did not change in response to playback. Consistent with previous studies, ambient temperature was inversely related to call duration and positively related to call rate. We conclude that noise affects the structure of spring peeper advertisement calls, and that spring peepers therefore have a mechanism for altering signal structure in response to noise. Future studies should test if other types of noise, such as biotic or anthropogenic noise, have similar effects on call structure, and if the observed changes to call structure enhance or impair communication in noisy environments [Current Zoology 60 (4): 438–448, 2014].
