Data from: Hiding among colors: Background color diversity impedes detection time
<p><span>Avoiding detection is vital for the survival of many animals. Factors extrinsic to animals, such as the visual complexity of the background, have been shown to impede the detection of animals. Studies using artificial and natural backgrounds have attributed background complexity to various visual features of the background. One feature that has received less attention is the diversity of color (hue) in the background. We used chickens and artificial backgrounds containing perceptually distinct elements in experiments to test whether color and luminance diversity affect detection time. We found that color diversity in the background impeded detection, while color diversity in prey and luminance diversity in the background did not impede detection. We also did not find an effect of luminance contrast on detection time. Our study suggests a prey animal can benefit in terms of increased detection times by predators when resting on backgrounds with enhanced color diversity.</span></p>

Data from: Hiding behavior in Christmas tree worms on different time scales
Many animals escape predators by hiding. Hiding decisions are economic in that individuals trade off the physiological costs of hiding with the benefits of increased security. The number of conspecifics may increase competition, security, or attract predators, influencing predation risk. We studied hiding time in Christmas tree worms (Spirobranchus giganteus), sessile marine invertebrates, which lived with 0–17 other worms within 20cm. Competition and predation risk reduction both predict a shorter latency to re-emerge given the necessity to feed and potential for safety in numbers, respectively. In contrast, if grouped worms attract more predators, individuals should hide longer. We experimentally induced hiding in 174 worms and found a significant, positive relationship between hiding time and number of conspecifics. We repeated the test 4 consecutive times in 1 day on a subset of 30 worms that were either solitary or lived with one other untested worm. We found that worms with longer hiding times habituated more quickly than worms with shorter hiding times, and that the individual worm explained 55.8% of the variation in hiding time. When we conducted the trials for 4 days, we found that the individual worm explained 41.75% of the variation, but no evidence of behavioral plasticity. Worm antipredator responses were consistently individualistic, but behavioral plasticity was only evident over short time scales. For sessile marine invertebrates, higher densities may attract predators, enhancing rather than diluting predation risk. Worms that cannot move away from their neighbors, thus seemingly modify antipredator behavior in consistent ways.
