If rain never comes the eggs will remain dormant through the winter if temperatures do not fall too low, then hatch the following spring (Flank 1999). Larval Marbled Salamanders are prey for numerous species, especially invertebrates including dragonfly naiads (Odonata), spiders (Arachnida), dytiscid beetle larvae and adults (Coleoptera), and giant water bugs (Bellostomatidae). the state that some animals enter during winter in which normal physiological processes are significantly reduced, thus lowering the animal's energy requirements. We tested for local adaptation in Wood Frog (Rana sylvatica) populations that face varying selection from an apex predator, the Marbled Salamander (Ambystoma opacum), which is expanding its distribution in the study region.
