Postembryonic ontogeny of the spadefoot toad, Scaphiopus
intermontanus (Anura: Pelobatidae): External morphology.
The frog diversity observed during the course of this study includes the first record of the Eastern Spadefoot, Scaphiopus
holbrookii, in St.
Adaptive plasticity in amphibian metamorphosis: response of Scaphiopus
hammondii tadpoles to habitat desiccation.
Rubin returned to the site the same evening, along with another student, Phil Evers, and found a single spadefoot toad, Scaphiopus
holbrookii, in the flooded meadow.
The pool is a site that is used for breeding by three species of amphibians; Ambystoma maculatum, Ambystoma opacum, and Scaphiopus

These sites have produced 4261 amphibian captures of six different species: one salamander (Ambystoma tigrinum) and five frogs (Rana sylvatiea, Ranapipiens, Bufo cognatus, Pseudacris maculata, and Scaphiopus
The two missing species were Gastrophryne carolinensis and Scaphiopus
holbrookii, each recognized as being secretive, burrowing anurans that favor habitats with sandy, gravelly, or other loose soils (Conant and Collins, 1998).

hurterii and the Plains spadefoot, Spea bombifrons (Anura: Scaphiopodidae), from southern Oklahoma.
The Eastern Spadefoot, Scaphiopus
holbrookii, an anuran that ranges widely across eastern North America, exhibits latitudinal variation in breeding activity.
Previous field work found that amphibian species that use the pond for breeding include Ambystoma maculatum, Ambystoma opacum, and Scaphiopus
