Digestive Phenotypic Flexibility in Post-Metamorphic Amphibians: Studies on a Model Organism

Studies of phenotypic flexibility are central to the understanding of evolutionary and comparative physiology. Research conducted on many vertebrate species has shown that the digestive system is highly responsive and sensitive to environmental cues. However, amphibians, which are a standard and cla...
