temperatures above 13 degrees Celsius. The adults are often found in open sun, basking on “gravel bars, boulders and cobbles,” because they are “heliotherms” (their body temperature warms by sun’s rays). Their eggs are deposited in shallow water in open sunlight near their cobbles and boulders. Rough-skinned newts can be found in headwater channels or terrestrial habitats. In 2010, Western fence lizards are found along alluvial channels of the river. This number increases as the water temperature and the level of sediment increases. They stay near the warmer climates because their invertebrate prey is more accessible here.
