Item Advertisement call length preferences of female Cope's gray treefrogs (Hyla chrysoscelis) in two-alternative choice tests(2020-07-23) LaBarbera, Katie; Nelson, Peggy B; Bee, Mark A; klabarbe@umn.edu; LaBarbera, Katie; University of Minnesota Animal Communication LabFemale Hyla chrysoscelis collected from the wild during the breeding season were tested in two-alternative choice tests for their preference between two synthetic calls, modeled closely after wild male calls, differing in their call length. This experiment was designed to examine whether females exhibit proportional processing (e.g., Weber's Law) of the acoustic signal. The data are being released along with the publication based upon them.Item Data for: Inconsistent sexual signaling degrades optimal mating decisions in animals(2020-03-09) Tanner, Jessie C; Bee, Mark A; jessie.c.tanner@gmail.com; Tanner, Jessie C; University of Minnesota Animal Communication LabData from a series of phonotaxis tests used to investigate the effects of within-individual variation (inconsistency) in male signals and ambient chorus noise on female mating decisions in Cope's gray treefrog. This dataset is among only a few generated to examine the effects of within-individual variation in signal production on animal communication. The data are now being released in support of a publication describing our findings.Item Data for: Species recognition is constrained by chorus noise, but not inconsistency in signal production, in Cope's gray treefrog (Hyla chrysoscelis)(2020-06-18) Tanner, Jessie C; Bee, Mark A; jessie.c.tanner@gmail.com; Tanner, Jessie C; University of Minnesota Animal Communication LabOptimal mate choice based on the assessment of communication signals can be constrained by multiple sources of noise. This dataset was created to examine the effects of two possible noise sources: ambient noise caused by the treefrog chorus and the inconsistency in signal production inherent to many animal communication systems. Our data were generated using two-choice phonotaxis tests of female Cope's gray treefrogs.Item Frogs Exploit Statistical Regularities in Noisy Acoustic Scenes to Solve Cocktail-Party-Like Problems(2017-02-13) Lee, Norman; Ward, Jessica L; Vélez, Alejandro; Micheyl, Christophe; Bee, Mark A; lee33@stolaf.edu; Lee, NormanThis submission is a supplement to the paper entitled “ Frogs Exploit Statistical Regularities in Noisy Acoustic Scenes to Solve Cocktail-Party-Like Problems” by Lee et al. (2017) published in Current Biology. In this paper, we develop an auditory filterbank inspired by the frog peripheral auditory system to quantify the natural scene statistics of frog breeding choruses. We show that natural chorus noise exhibits a high-level of spectrotemporal correlation (comodulation) among frequencies emphasized in advertisement calls. In 4 psychophysical experiments, we demonstrate that treefrogs can exploit comodulation in background noise to mitigate noise-induced errors in evolutionary critical mate-choice decisions.Frogs experienced fewer errors in recognizing conspecific calls and in selecting calls of high-quality mates in the presence of comodulated noise. This submission includes an implementation of the frog auditory filterbank in Matlab, source data, and other Matlab code used in data analyses to generate the main and supplemental figures presented in Lee et al. (2017).
