Pond-Breeding Amphibian Guild
Supplemental Volume: Species of Conservation Concern SC SWAP 2015 Pond-breeding Amphibians Guild Primary Species: Flatwoods Salamander Ambystoma cingulatum Carolina Gopher Frog Rana capito capito Broad-Striped Dwarf Siren Pseudobranchus striatus striatus Tiger Salamander Ambystoma tigrinum Secondary Species: Upland Chorus Frog Pseudacris feriarum -Coastal Plain only Northern Cricket Frog Acris crepitans -Coastal Plain only Contributors (2005): Stephen Bennett and Kurt A. Buhlmann [SCDNR] Reviewed and Edited (2012): Stephen Bennett (SCDNR), Kurt A. Buhlmann (SREL), and Jeff Camper (Francis Marion University) DESCRIPTION Taxonomy and Basic Descriptions This guild contains 4 primary species: the flatwoods salamander, Carolina gopher frog, dwarf siren, and tiger salamander; and 2 secondary species: upland chorus frog and northern cricket frog. Primary species are high priority species that are directly tied to a unifying feature or habitat. Secondary species are priority species that may occur in, or be related to, the unifying feature at some time in their life. The flatwoods salamander—in particular, the frosted flatwoods salamander— and tiger salamander are members of the family Ambystomatidae, the mole salamanders. Both species are large; the tiger salamander is the largest terrestrial salamander in the eastern United States. The Photo by SC DNR flatwoods salamander can reach lengths of 9 to 12 cm (3.5 to 4.7 in.) as an adult. This species is dark, ranging from black to dark brown with silver-white reticulated markings (Conant and Collins 1991; Martof et al. 1980). The tiger salamander can reach lengths of 18 to 20 cm (7.1 to 7.9 in.) as an adult; maximum size is approximately 30 cm (11.8 in.). -
The Origins of Chordate Larvae Donald I Williamson* Marine Biology, University of Liverpool, Liverpool L69 7ZB, United Kingdom

It contests the view that larvae and corresponding adults evolved from common ancestors. The present paper reviews the life histories of chordates, and it interprets them in terms of the larval transfer hypothesis. It is the first paper to apply the hypothesis to craniates. I claim that the larvae of tunicates were acquired from adult larvaceans, the larvae of lampreys from adult cephalochordates, the larvae of lungfishes from adult craniate tadpoles, and the larvae of ray-finned fishes from other ray-finned fishes in different families. The occurrence of larvae in some fishes and their absence in others is correlated with reproductive behavior. Adult amphibians evolved from adult fishes, but larval amphibians did not evolve from either adult or larval fishes. I submit that [1] early amphibians had no larvae and that several families of urodeles and one subfamily of anurans have retained direct development, [2] the tadpole larvae of anurans and urodeles were acquired separately from different Mesozoic adult tadpoles, and [3] the post-tadpole larvae of salamanders were acquired from adults of other urodeles. Reptiles, birds and mammals probably evolved from amphibians that never acquired larvae. -

Fiftee N Vertebrate Beginnings the Chordates
Hickman−Roberts−Larson: 15. Vertebrate Beginnings: Text © The McGraw−Hill Animal Diversity, Third The Chordates Companies, 2002 Edition 15 chapter •••••• fifteen Vertebrate Beginnings The Chordates It’s a Long Way from Amphioxus Along the more southern coasts of North America, half buried in sand on the seafloor,lives a small fishlike translucent animal quietly filtering organic particles from seawater.Inconspicuous, of no commercial value and largely unknown, this creature is nonetheless one of the famous animals of classical zoology.It is amphioxus, an animal that wonderfully exhibits the four distinctive hallmarks of the phylum Chordata—(1) dorsal, tubular nerve cord overlying (2) a supportive notochord, (3) pharyngeal slits for filter feeding, and (4) a postanal tail for propulsion—all wrapped up in one creature with textbook simplicity. Amphioxus is an animal that might have been designed by a zoologist for the classroom. During the nineteenth century,with inter- est in vertebrate ancestry running high, amphioxus was considered by many to resemble closely the direct ancestor of the vertebrates. Its exalted position was later acknowledged by Philip Pope in a poem sung to the tune of “Tipperary.”It ends with the refrain: It’s a long way from amphioxus It’s a long way to us, It’s a long way from amphioxus To the meanest human cuss. Well,it’s good-bye to fins and gill slits And it’s welcome lungs and hair, It’s a long, long way from amphioxus But we all came from there. But amphioxus’place in the sun was not to endure.For one thing,amphioxus lacks one of the most important of vertebrate charac- teristics,a distinct head with special sense organs and the equipment for shifting to an active predatory mode of life. -

Pond-Breeding Amphibian Guild
Pond-breeding Amphibian Guild PRIMARY SPECIES Flatwoods Salamander Ambystoma cingulatum Carolina Gopher Frog Rana capito capito Broad-Striped Dwarf Siren Pseudobranchus striatus striatus Tiger Salamander Ambystoma tigrinum SECONDARY SPECIES Upland Chorus Frog Pseudacris triseriata coastal plain only Northern Cricket Frog Acris crepitans coastal plain only Contributors: Stephen Bennett and Kurt A. Buhlmann DESCRIPTION Taxonomy and Basic Descriptions This guild contains four primary species, flatwoods salamander, Carolina gopher frog, dwarf siren and tiger salamander and two secondary species, upland chorus frog and northern cricket frog. Primary species are high priority species that are directly tied to a unifying feature or habitat. Secondary species are priority species that may occur in or be related to the unifying feature at some time in their life. The flatwoods salamander and tiger salamander are members of the family Ambystomatidae, the mole salamanders. Both species are large; the tiger salamander is the largest terrestrial salamander in the eastern United States. The flatwoods salamander can reach lengths of 9 to 12 cm (3.5 to 4.7 inches) as an adult. This species is dark, ranging from black to dark brown with silver- white reticulated markings (Conant and Collins 1991; Martof et al. 1980). The tiger salamander can reach lengths of 18 to 20 Photo by SC DNR cm (7.1 to 7.9 inches) as an adult; maximum size is approximately 30 cm (11.8 inches). This species has a dark background, typically black, with bright, yellow-orange irregular markings (Conant and Collins 1991; Martof et al. 1980). The broad-striped dwarf siren is a member of the family Sirenidae, a family of salamanders that consists of both dwarf sirens and sirens.
