Effect of Environment and Ontogeny on Color Pattern Variation in Arizona Tiger Salamanders (Ambystoma tigrinum nebulosum Hallowell)

We assessed effect of microhabitat and ontogeny on color pattern variation within and among three populations of Ambystoma tigrinum nebulosum Hallowell from the Mogollon Rim of central Arizona. Laboratory and field observations show that salamander color correlates with substrate color and water
