Pacific chorus frog (Pseudacris regilla)

The Pacific Tree Frog (Pseudacris regilla) is a species of tree frogs.

The Pacific chorus frog Pseudacris Regilla can be found in abundance across the state's Sierra Nevada mountain range.

The taxonomic confusion introduced by this name change means that much of the information about Pseudacris sierra is attached to the name Pseudacris regilla.

The Amphibian Species of the World 6.0 recognizes the split, but uses the name Pseudacris regilla for the northern component, the definition followed in this article.

However, if this split is accepted, the correct name (i.e., the oldest available name) for the northern component is Pseudacris regilla and for the central one Pseudacris sierra.

Pacific Tree Frog (Pseudacris regilla) has a range from the West Coast of the United States (from Northern California, Oregon, and Washington) to British Columbia, in Canada.

Recuero et al. attached the name Pseudacris regilla to the northern species, renaming the central species the Sierran tree frog (Pseudacris sierra) and the southern piece the Baja California tree frog (Pseudacris hypochondriaca).

Experimental exposure to Ribeiroia ondatrae cercariae has been shown to cause limb malformations in various frog, toad and salamander species, including Pseudacris regilla, Anaxyrus boreas, Rana pipiens, A. americanus, Ambystoma macrodactylum, R. clamitans and R. sylvatica.

In enclosure experiments, the survival to metamorphosis of both the Red-legged Frog and the Pacific Treefrog (Pseudacris regilla) in permanent pools tended to be low when compared to temporary pools, regardless of the presence or absence of Bullfrog tadpoles (Adams 2000).

For example, White's tree frog (Litoria caerulea) varies between pale green and dull brown according to the temperature, and the Pacific tree frog (Pseudacris regilla) has green and brown morphs, plain or spotted, and changes colour depending on the time of year and general background colour.
