Distribution and Habitat
Country distribution from AmphibiaWeb's database: United States
U.S. state distribution from AmphibiaWeb's database: Alabama
Habitat preferred by Phaeognathus hubrichti is steep, mesic ravines shaded by a mature hardwood overstory (Jordan 1975; Schwaner and Mount 1970) P. hubrichti is almost entirely fossorial and appears to be found most often in areas of soft soil which allows burrowing. P. hubrichti burrows are often most abundant on the steepest regions of slopes (Valentine 1963b). Burrows are subject to constant erosion and burrow openings may only last a few motnhs, at which point the salamander must repair or reconstruct its burrow (Gunzburger and Guyer 1998).
Life History, Abundance, Activity, and Special Behaviors
Phaeognathus hubrichti are often observed sitting with just their head visible at the entrance of their burrow on moist nights. P. hubrichti probably forages opportunistically on any prey item that passes by the burrow entrance or enters the burrow. Diet of P. hubrichti consists of a variety of invertebrates including snails, beetles, ants, millipedes, and spiders (Brandon 1965; Gunzburger 1999).
Analysis of proteins from individuals from 13 populations of Phaeognathus hubrichti throughout their range suggests that there are 2 distinct geographic groups (McKnight et al. 1991). An effort to conserve population within both of these groups should be attempted.
