Data from: Similarity in temporal variation in sex-biased dispersal over short and long distances in the dark-eyed junco, Junco hyemalis

Eric B. Liebgold, Nicole M. Gerlach & Ellen D. Ketterson
Patterns of sex-biased dispersal are typically consistent within taxa, e.g., female-biased in birds and male-biased in mammals, leading to theories about the evolutionary pressures that lead to sex-biased dispersal. However, generalizations about the evolution of sex biases tend to overlook that dispersal is mediated by ecological factors that vary over time. We examined potential temporal variation in between- and within-population dispersal over an 11-year period in a bird, the dark-eyed junco (Junco hyemalis). We measured...

Data from: Interactions of multisensory components perceptually rescue túngara frog mating signals

Ryan C. Taylor & Michael J. Ryan
Sexual signals are often complex and perceived by multiple senses. How animals integrate signal components across sensory modalities can influence signal evolution. Here we show that two relatively unattractive signals that are perceived acoustically and visually can be combined in a pattern to form a signal that is attractive to female túngara frogs. Such unanticipated perceptual effects suggest that the evolution of complex signals can occur by alteration of the relationships among already-existing traits.

Data from: Risky ripples allow bats and frogs to eavesdrop on a multisensory sexual display

Wouter Halfwerk, Patty L. Jones, Ryan C. Taylor, Michael J. Ryan & Rachel A. Page
Animal displays are often perceived by intended and non-intended receivers in more than one sensory system. In addition, cues that are an incidental consequence of signal production can also be perceived by different receivers, even when the receivers employ different sensory systems to perceive them. Here, we show that vocal responses of male túngara frogs (Physalaemus pustulosus) increase two-fold when call-induced water ripples are added to the acoustic component of a rival’s call. Hunting bats...
