“…, Ciccotto and Mendelson , Roberts and Mendelson , Roberts et al. ); moreover, darters are stream‐dwelling fish for which olfactory cues may be relatively ineffective. Importantly, however, we compare our results with those of a previous study testing mate choice in the same focal species pairs in artificial streams, where individuals had full physical access to mates and expressed their preferences by spawning (Martin and Mendelson , see next).…”

Preference for conspecifics evolves earlier in males than females in a sexually dimorphic radiation of fishes

Speciation by sexual selection is generally modeled as the coevolution of female preferences and elaborate male ornaments leading to behavioral (sexual) reproductive isolation. One prediction of these models is that female preference for conspecific males should evolve earlier than male preference for conspecific females in sexually dimorphic species with male ornaments. We tested that prediction in darters, a diverse group of freshwater fishes with sexually dimorphic ornamentation. Focusing on the earliest stages of divergence, we tested preference for conspecific mates in males and females of seven closely related species pairs. Contrary to expectation, male preference for conspecific females was significantly greater than female preference for conspecific males. Males in four of the 14 species significantly preferred conspecific females; whereas, females in no species significantly preferred conspecific males. Relationships between the strength of preference for conspecifics and genetic distance revealed no difference in slope between males and females, but a significant difference in intercept, also suggesting that male preference evolves earlier than females'. Our results are consistent with other recent studies in darters and suggest that the coevolution of female preferences and male ornaments may not best explain the earliest stages of behavioral isolation in this lineage.

“…It is, however, possible that even closely related species differ in their response to video stimuli. For example, Roberts, Gumm & Mendelson (2017) tested the efficacy of video playback in two species of darters, Etheostoma barrenense and Etheostoma zonale , and found that despite the same experimental set-up and close relatedness of the species, only E. zonale females’ responses to video playback of conspecific males were comparable to live males, whereas E. barrenense females showed a preference only for live males. Similarly, blue tits might respond to videos differently than great tits.…”

Video playback provides a promising method to study social interactions, and the number of video playback experiments has been growing in recent years. Using videos has advantages over live individuals as it increases the repeatability of demonstrations, and enables researchers to manipulate the features of the presented stimulus. How observers respond to video playback might, however, differ among species, and the efficacy of video playback should be validated by investigating if individuals’ responses to videos are comparable to their responses to live demonstrators. Here, we use a novel foraging task to compare blue tits’ (Cyanistes caeruleus) responses to social information from a live conspecific vs video playback. Birds first received social information about the location of food, and were then presented with a three-choice foraging task where they could search for food from locations marked with different symbols (cross, square, plain white). Two control groups saw only a foraging tray with similar symbols but no information about the location of food. We predicted that socially educated birds would prefer the same location where a demonstrator had foraged, but we found no evidence that birds copied a demonstrator’s choice, regardless of how social information was presented. Social information, however, had an influence on blue tits’ foraging choices, as socially educated birds seemed to form a stronger preference for a square symbol (against two other options, cross and plain white) than the control birds. Our results suggest that blue tits respond to video playback of a conspecific similarly as to a live bird, but how they use this social information in their foraging decisions, remains unclear.

“…In this study, our aim was to validate the use of computer animations in the banded darter Etheostoma zonale by comparing behavior between live and animation trials. Previous work with this species validated the use of video playback studies (Roberts et al. 2017) and motorized models (Williams and Mendelson 2011), showing that preferences for conspecific over heterospecific stimuli in playback and motorized model trials were not significantly different than preferences in live trials.…”
