Understanding the Information Value of Repeated Exposure to Chemical Alarm Cues: what Can Growth Patterns Tell us?

摘要: Chemical cues released into the environment from injured prey animals provide a rich source of information about ambient risk. However, these could also not associated with predation Here we exposed wood-frog tadpoles (Lithobates sylvaticus) to control diet and one that was soaked in chemical conspecifics, documented growth development tadpoles. If perceive repeated exposure conspecific as indicating high risk environment, then predict would reduce foraging, prolonging time metamorphosis, reducing rate initiating adaptive changes tail morphology. Conversely, if interpret an indicator competitor density, they should increase body size become better competitors. We found exhibited significantly larger width length relative control. These patt...
