Document Summary
Intraspecies within species wood frog vs spadefoot toad. Interspecies among species families of anurans: life history strategy fig. Increasing size and reducing amount of energy put into reproduction: environmental differences. Phenotypic plasticity: a single genotype may produce different phenotypes under different environmental conditions. Phenotypic plasticity that responds to temp variation often produces a continuous range of sizes. In other types there will only be one discrete size. Phenotypic plasticity in spadefoot toad tadpoles fig 7. 5. The great basin spadefoot (spea intermontana) is a species of toad in the scphiopodidae family. They have a hard-part on each of the hind feet that allow them to dig underground (fossorial) Anuran metamorphosis is a phenotypically plastic trait. Phenotypic plasticity may result in a continuous range of sizes; or discrete types called morphs. The morphological variation between these new mexico spadefoot toad tadpoles stems largely from differences in diet.
