Simulated data for: The evolution of mating preferences for genetic attractiveness and quality in the presence of sensory bias
<p>This repository contains simulated datasets relating to the publication: </p> <p>Henshaw JM, Fromhage L, Jones AG (2022) The evolution of mating preferences for genetic attractiveness and quality in the presence of sensory bias. Proc. Natl. Acad. Sci. USA (doi:10.1073/pnas.2206262119)</p> <p>In this paper, we simulate the evolution of female preferences for multiple male ornament types (e.g., 'Fisherian', 'handicap' and 'indicator' ornaments) that differ in their associations with genes for attractiveness and for general 'quality' (operationalized as the ability to acquire resources). We allowed for ornaments to differ in their saliency to females. We also analyze the causal mechanisms generating sexual selection (e.g., 'good genes' and 'sexy sons') using causal inference. </p> <p>Datasets are organised into ZIP files named after the corresponding figure in the publication.

Data for: Sensory biases in response to novel complex acoustic signals in male and female gray treefrogs, Hyla chrysoscelis
<p>The sensory bias hypothesis proposes that female preferences for male sexual signaling traits evolved in contexts other than mating. Individuals of both sexes may experience similar selection pressures in these contexts, thus males may have similar biases to females for variation in signal traits. We tested this prediction in the gray treefrog, <em>Hyla chrysoscelis</em>, in which males produce simple advertisement calls, but females are more attracted to certain novel complex stimuli. We recorded males' responses to playbacks of both simple advertisement calls and complex calls consisting of the advertisement call with an acoustic appendage (filtered noise, or heterospecific call pulses) either leading or following the call. We tested females' preferences for the same stimuli in phonotaxis tests. We found evidence for a sensory bias in both sexes: males gave more aggressive calls in response to complex stimuli and females sometimes preferred complex over simple calls. These biases were not universal and depended on both temporal order and appendage characteristics, but how these effects manifested differed between the sexes. Ultimately, our approach of studying biases of both sexes in response to novel mating signals will shed light on the origin of mating preferences, and the mechanisms by which sensory biases operate.</p>

Female preference for colour-enhanced males: a test of the sensory bias model in medaka, a drab fish
<p>Sexual selection research has long focused on the evolution of female mate preferences. Most of the models that have been developed posit that mate preferences evolve in a mating context. In contrast, the sensory bias model proposes that mate choice preferences arise in a non-mating context, as a by-product of natural selection acting on a female's perceptual system. Recent research has shown that many species of fishes, from across a large clade including poeciliids, goodeids, and medaka, have a bias for long wavelength (LW) colors (yellow, orange, red) in a non-mating context. Even species that do not have LW-colored ornaments, apparently because they have been lost secondarily, retain this latent bias for LW colors. Here, we predicted that female <i>Oryzias latipes </i>(Japanese medaka), a drab species with a latent preference for LW colors, would show a mate choice preference for males with an artificial secondary sexual trait—a colored stripe added to their flank. We confirmed that females were more responsive to red and orange objects in a non-mating context than to other colors. We also showed that females were less resistant towards males with a LW-colored stripe than to those enhanced with a non-LW stripe and that, for many females, responses towards specific LW colors were consistent across these non-mating and mating contexts. Therefore, our results provide support for the sensory bias model by providing a link between a sensory bias in a non-mating context and a mate choice preference in a drab species like medaka.</p>
Data from: A sensory bias overrides learned preferences of bumblebees for honest signals in Mimulus guttatus
<p class="CxSpFirst">Insect pollinators readily learn olfactory cues, and this is expected to select for "honest signals" that provide reliable information about floral rewards. However, plants might alternatively produce signals that exploit pollinators' sensory biases, thereby relaxing selection for signal honesty. We examined the innate and learned preferences of <i>Bombus impatiens</i> for <i>Mimulus guttatus</i> floral scent phenotypes corresponding to different levels of pollen rewards in the presence and absence of the innately attractive floral volatile compound β-trans-bergamotene. Bees learned to prefer honest signals after foraging on live <i>M. guttatus</i> flowers, but only exhibited this preference when presented floral scent phenotypes that did not include β-trans-bergamotene. Our results suggest that a sensory bias for β-trans-bergamotene overrides the ability of <i>B. impatiens</i> to use honest signals when foraging on <i>M. guttatus</i>. This may represent a deceptive pollination strategy that allows plants to minimize investment in costly rewards without incurring reduced rates of pollinator visitation.</p>
