The neotenic amphibians are species that present a phyletically truncated development with absence of a complete metamorphosis, as well known in Ambystomatidae
family (Reilly & Brandon, 1994), this species of ambystomatidae
like mole salamanders retaining larval characteristics, what has been described as an adaptation to aquatic life (Reilly & Brandon).
When moisture levels in forest environments decrease, plethodontid salamanders rely more heavily upon DCWD for refuge than other salamanders (i.e., those in the family Ambystomatidae
, Owens et al, 2008) due to the plethodontids reliance on sustained moist conditions for dermal respiration.
Reproduction ex situ en Ambystoma granulosum y Ambystoma lermaense (Amphibia: Ambystomatidae
sp., from the Pacific Northwest, USA (Amphibia: Caudata: Ambystomatidae
We include the Lago de Patzcuaro salamander Ambystoma dumerilli (Ambystomatidae
) in the analysis because it is functionally equivalent to a fish in the ecosystem (Mercado-Silva et al., 2002).
Most of these paedomorphic species belong to the Family Ambystomatidae
, and paedomorphic species are either obligatory paedomorphs or facultative paedomorphs.
The most complex condition, found in the Ambystomatidae
, Hynobiidae, Proteidae, Salamandridae, and Siren idae, consists of the following ducts leading from the testes sequentially: the vasa efferentia, Bidder's duct (longitudinal collecting duct), afferent epididymal ducts, and efferent epididymal ducts.
Endoparasites of the smallmouth salamander, Ambystoma texanum (Caudata: Ambystomatidae
) from Dallas County, Texas.
Because of this and the overall size of the vertebra (see below) SEKI-20167 does not belong to Ambystoma (mole salamanders, Ambystomatidae
) or Diacamptodon (giant salamanders, Dicamptodontidae [Dicamptodontinae of Frost et al.
Species that were collected in this survey that are not included in Minton (2001) belong to the Ambystomatidae
Key words: Ambystoma talpoideum, Ambystomatidae
, harmonic radar detection, mole salamanders, terrestrial habitat, reflector tag, tracking
The wildlife area contains extensive marshland and abundant temporary aquatic habitats (ponds, roadside ditches) that serve as breeding areas for anurans and pond breeding caudates (Ambystomatidae
) that cannot coexist with predatory fish.
