Female Preferences for Aposematic Signal Components in a Polymorphic Poison Frog
Martine E. Maan and Molly E. Cummings, University of Texas at Austin, Integrative Biology
Aposematic signals may be subject to conflicting selective pressures from predators and conspecifics. We studied female preferences for different components of aposematic coloration in the polymorphic poison frog Oophaga pumilio across several phenotypically distinct populations.
Male reflectance spectra. Curves represent average reflectances of all males used in the experiments. Gray areas indicate between-individual variation (standard errors). Left panels are dorsal reflectance spectra; right panels are ventral Male reflectance spectra. Curves represent average reflectances of all males used in the experiments.
