(Cocroft and Ryan, 1995; Ervin, 2020; Ewert, et al., 2001), California tree frog tadpoles are known to be generalists, with a diet consisting of plant material, periphyton from algal mats, and organic detritus found in their natal ponds (Ervin, 2020). Eggs appear to be resistant to the negative effects of solar UV-B radiation and even to increased water acidification. at https://www.jstor.org/stable/3892719. Many of the frogs rely on camouflage to protect themselves from predators, and the more arboreal species escape ground-dwelling predators by hiding in trees. Egg-laying takes place in slow streams, permanent, seasonal and artificial ponds, reservoirs, natural and roadside ditches, marshes, shallow vegetated wetlands, and wet meadows. The underside is creamy with yellow underneath the back legs. The range of this species is not clear, due to the small number of specimens sampled for the study that described it as a new species in 2006. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. (Stebbins & McGinnis, 2012). Some herpetologist believe that it is not accurate because there are no obvious differences in appearance or in the advertisement calls between the three species of frogs. They use loud advertising calls during the breeding season to let females and other males know how fit they are. 2. Observations on the ecology of the canyon tree frog, Hyla californiae. Treefrog Tadpoles Pictures, Images and Stock Photos However, attempts to hybridize these species in the laboratory have resulted in the production of inviable crosses that failed at the earliest stages of development (Maxon and Jameson, 1968; Ball and Jameson, 1970; Gaudin, 1979)."
