| Phenotypic plasticity comprises a central concept in the understanding of how organisms interact with their environment, and thus, is a central topic in ecology and evolution. A particular case of phenotypic plasticity is phenotypic flexibility, which refers to reversible change in organism traits due to changes in internal or external environmental conditions. Flexibility of digestive features has been analyzed for more than a century in a myriad of different species and contexts. Studies in rodents on gut size flexibility have been developed mainly from two different áreas of the biological sciences, physiology and ecology. However, as for several other topics related with physiological ecology, both kinds of studies largely developed along sepárate... |
