Topic: Pelobatidae


In the News (Thu 31 Dec 09)

  
  Pelobatidae
As generally used, Pelobatidae (for megophryines and pelobatines) is not demonstrably monophyletic, because of the ambiguous relationships of Pelodytes.
The name Pelobatidae was defined by Ford and Cannatella (1993) as the node that is the most recent common ancestor of living Pelobates, Scaphiopus, and Spea, and all of its descendants.
Synapomorphies of Pelobatidae include fusion of the joint between the sacrum and coccyx, exostosed frontoparietals, and the presence of a metatarsal spade supported by a well-ossified prehallux.

 Pelobatidae (Bonaparte, 1850) European Spadefoot Toads
The family Pelobatidae was formerly comprised of three genera, Pelobates from Europe, and Scaphioupus and Spea from North America.
Recently, the two American genera have been placed into their own family, Scaphiopodidae, leaving only Pelobates in the family Pelobatidae.
Synapomorphies of Pelobatids include a fused joint between the coccyx and the sacrum, exostosed frontoparietals, and the presences of the metatarsal spade.

Soc., 38: 273, considered the Sooglossidae to be included in the Pelobatidae (in the sense of including the Megophryidae of this list).
Almost all workers regarded the Scaphiopodidae as in the Pelobatidae prior to the study of García-París, Buchholz, and Parra-Olea, 2003, Mol.
Sinica, 8: 356-370, considered the Megophryidae to be a subfamily of the Pelobatidae and discussed the history of taxonomy of the group.

 Salientia
A derived character that refutes the monophyly of Mesobatrachia is the fusion of the third distal carpal to other carpals, which Pelodytes shares with Neobatrachia (Cannatella, 1985).
Pelobatoidea (Node G) The name was applied to the node that is the common ancestor of living Megophryidae, Pelobatidae, and Pelodytes.
Relationships among the living pelobatoids are an unresolved trichotomy of Megophryidae, Pelobatidae, and Pelodytes.

On August 13, 1999 two colleagues and I set out on an expedition to tag and track two species of pelobatidae (frogs).
These frogs were indigenous to a marl bog in South Carolina where the nutrient levels are higher to that of the muskeg in canada where they are also found.
It was then when we noticed that there was a large discrepancy between the number of females as opposed to males.

The sacrum possesses a combination of characters present in sacra of neobatrachian frogs from southern continents, and the atlas resembles those found among the Pelobatidae.
These fossils document the existence of multiple anuran taxa on Madagascar during the Late Cretaceous.
The tentative referral of the atlas to the Pelobatidae implies that this taxon, best known from northern continents, previously had a more cosmopolitan distribution.

(2003) used mtDNA to examine the phylogentic relationships of Pelobatoidea and found that the family Pelobatidae, as previously defined, is not monophyletic (Pelobates is sister to Megophryidae, not to Spea/Scaphiopus).
They split the Pelobatidae into two families: Eurasian spadefoot toads (Pelobates), which retain the name Pelobatidae, and North American spadefoot toads (Scaphiopus, Spea), which make up the revived family Scaphiopodidae.
Nearly endemic to central and southwestern California, also occurs in northwestern Baja California; extirpated from many sites in the Central Valley and coastal southern California; declining due to impacts of urbanization and agricultural development; some populations may be threatened by habitat fragmentation or exotic species (mosquitofish stocked for mosquito abatement, bullfrogs).
