Sexual Size Dimorphism in the Plethodontidae
2000Sexual size dimorphism (or SSD for short) is common in vertebrate animals. It reflects the adaptation of males and females to different reproductive or ecological roles. SSD is male-biased when males are larger than females (as is often the case in birds and mammals), and female-biased when females are larger than males (as in many ectothermic ...

Limb chondrogenesis of the seepage salamander, Desmognathus aeneus (Amphibia: Plethodontidae)
Journal of Morphology, 2005AbstractSalamanders are infrequently mentioned in analyses of tetrapod limb formation, as their development varies considerably from that of amniotes. However, urodeles provide an opportunity to study how limb ontogeny varies with major differences in life history.

Afferent visual projections in three species of lungless salamanders (family plethodontidae)
Neuroscience Letters, 1982Afferent visual projections were demonstrated in three species of plethodontid salamanders by means of anterograde transport of horseradish peroxidase. On the contralateral side three optic tracts and seven neuropil areas can easily be distinguished, which are similar among the three species examined as well as in European salamandrids.

Southeastern U.S. Coastal Plain Habitats of the Plethodontidae
2000Because the Coastal Plain is geologically and biologically a very distinct region of the southeastern United States—the southern portion having a nearly subtropical climate—the life cycles, ecology, and evolutionary relationships of its plethodontid salamanders may be significantly different from plethodontids in the Appalachians and Piedmont.

Aggression and Competition in Eastern Plethodon (Amphibia, Urodela, Plethodontidae)
Journal of Herpetology, 1976Aggression (including territoriality, social dominance, and feeding competi- tion) was observed among and between salamanders of different eastern large and eastern small Plethodon. The aggression affects the overlapping food and shelter use in sympatric Plethodon species, and so is a part of competition.

First Record of Bolitoglossa mulleri (Caudata: Plethodontidae) from Mexico
The Southwestern Naturalist, 1992The plethodontid salamander Bolitoglossa mulleri (Brocchi) is a member of the Bolitoglossamexicana species group and is known to occur in tropical and subtropical forests (approximately 100 to 1,500 m elev.) on the Gulf versant of Guatemala (Elias, 1984). The major taxonomic character differentiating B.
