Differential use of visual and chemical cues in predator recognition and threat-sensitive predator-avoidance responses by larval newts (Notophthalmus viridescens)

For prey under the threat of predation, the ability to distinguish between different levels of danger can have important fitness consequences. Larval central newts, Notophthalmus viridescens louisianensis, distinguished between predatory (Ambystoma tigrinum tigrinum larvae) and nonpredatory (Hyla ch...

More Information
Summary:For prey under the threat of predation, the ability to distinguish between different levels of danger can have important fitness consequences. Larval central newts, Notophthalmus viridescens louisianensis, distinguished between predatory (Ambystoma tigrinum tigrinum larvae) and nonpredatory (Hyla chrysoscelis/versicolor complex tadpoles) heterospecifics, but only when chemical cues were available.
