Amphibiaweb's Illustrated Amphibians of the Earth
AmphibiaWeb's Illustrated Amphibians of the Earth Created and Illustrated by the 2020-2021 AmphibiaWeb URAP Team: Alice Drozd, Arjun Mehta, Ash Reining, Kira Wiesinger, and Ann T. Chang This introduction to amphibians was written by University of California, Berkeley AmphibiaWeb Undergraduate Research Apprentices for people who love amphibians. Thank you to the many AmphibiaWeb apprentices over the last 21 years for their efforts. Edited by members of the AmphibiaWeb Steering Committee CC BY-NC-SA 2 Dedicated in loving memory of David B. Wake Founding Director of AmphibiaWeb (8 June 1936 - 29 April 2021) Dave Wake was a dedicated amphibian biologist who mentored and educated countless people. With the launch of AmphibiaWeb in 2000, Dave sought to bring the conservation science and basic fact-based biology of all amphibians to a single place where everyone could access the information freely. Until his last day, David remained a tirelessly dedicated scientist and ally of the amphibians of the world. 3 Table of Contents What are Amphibians?

Effects of land cover Watersheds change on species can be direct (when habitat is converted to alternative land cover types) or indirect (when Structural equation model land outside of the species habitat is altered). Hydrologic and ecological connections between terrestrial and California aquatic systems are well understood, exemplifying how spatially disparate land cover conditions may influence Arroyo toad aquatic habitats, but are rarely examined. We sought to quantify relative effects of land cover at two different but Anaxyrus californicus interacting scales on habitat suitability for the endangered arroyo toad (Anaxyrus californicus). Based on an Anthropogenic development ff Riparian areas existing distribution model for the arroyo toad and available land cover data, we estimated e ects of land cover along streams and within entire watersheds on habitat suitability using structural equation modeling. -

The species was discovered in 1996 and was determined to occupy 26.7 km of the San Antonio River from approximately 2.4 km northwest of the San Antonio Mission de Padua, to the river delta above the San Antonio Reservoir. The construction of the San Antonio Reservoir dam in 1963 isolated this northern population of arroyo toads. Through time, the Fort Hunter Liggett landscape has changed drastically. The land was heavily grazed by cattle until 1991, which considerably reduced vegetation in riparian areas. Military training following acquisition of the land in 1940 far exceeded current allowable training. Fire was used extensively to reduce unfavorable vegetation, and as a result, extreme tree loss occurred through the ranges. -

Frequently Asked Questions About Critical Habitat for the Endangered Arroyo Toad
Frequently Asked Questions about Critical Habitat for the Endangered Arroyo Toad Q. What is the arroyo toad? The arroyo toad (Bufo californicus) is a small, light greenish-grey or buff-colored toad with dark-spotted, warty skin. Arroyo toads were historically found in streams and river basins in California from San Luis Obispo County to San Diego County, and south to Baja California, Mexico. Within the United States, populations of the arroyo toad are currently found in river basins in Monterey, Santa Barbara, Ventura, Los Angeles, Orange, Riverside, San Bernardino, and San Diego counties. On December 16, 1994, the U.S. Fish and Wildlife Service (Service) listed the species as endangered, under the Endangered Species Act (Act). Q. What habitats does the arroyo toad need? Arroyo toads prefer shallow pools and open, sandy stream terraces with cottonwoods, oaks, or willows. They breed in streams that have enough water from late March to mid-June to support the tadpoles until they change into toads. Females lay eggs in shallow, slow moving portions of streams that have little or no vegetation. Juveniles and adults forage for insects on sand and gravel bars with little or no grass or other low-growing cover. Subadult and adult arroyo toads excavate shallow burrows on sand bars, stream side terraces or in the uplands where they shelter during the day when the surface is damp, or for longer intervals during the dry season. Because arroyo toad habitats are favored sites for water storage reservoirs, flood control structures, roads, agriculture, urban development, and recreational facilities such as campgrounds and off-highway vehicle parks, many arroyo toad populations were reduced in size or eliminated due to extensive habitat loss from 1920 into the 1990s.
