A chytrid fungus, Batrachochytrium dendrobatidi!>, causes the deterioration of the keratinized mouthparts of tadpoles (Nichols et al. 200 I), and has been implicated in amphibian declines in Australia, the Neotropics, and in Europe (Berger et al. 1998; Bosch et al. 200 I). The fungus is widespread, and has been identified on six continents: Africa, South America, Central America, North America, Europe, and Australia (Speare and Berger 2000). In Cali­fornia, chyuids have been identified in nine amphibian taxa (Rana muscosa, RaJW aurora drayton ii, Rana aurora aurora, Rana boylii, Rana catesbeiana, Bufo canorus, Hyla reg ilia, Spea hammondii, and Ambystoma macrodactylum croceum; Fellers et aI., in press); however, it is not known whether they are the cause of population declines.

collection of voucher specimens, will be an important tool in de­termining the extent and severity of chytrid infection. This shouldbe particularly easy in frogs with large tadpoles such as the moun­tain yellow-legged frog, R. muscosa (Vredenburg et aI., in press).The symptoms of chytridiomycosis include loss of black pigmentfrom jaw sheaths and tooth rows witrun 1-3 weeks of infection(Fellers et aI., in press).

The photograph above shows R. muscosa with two potentialstages of chytridiomycosis infection b), and c) and one apparentlyuninfected animal a). The alTOW indicates the lower jaw sheath inall three photos. Notice that a) has complete tooth rows and darkjaw sheaths while b) is lacking dark tooth rows and has only a thindark line on the jaw sheaths. In c) the beak and tooth rows arecompletely colorless. Tadpole a) was collected in 1976 near SonoraPass, Alpine County, California, USA (MVZ 137435). Tadpolesb), and c) were collected near Ebbetts Pass, 2 June 2001, AlpineCounty, California, USA (MVZ, not accessioned). Tadpoles b) andc) are being histologically analyzed. Recently, however, 1.Longcore (pers. comm.) cultivated a Batrachochytrium fungusfrom R. muscosa in the Sierra Nevada and we expect these willalso contain the fungus.

We ask that any herpetologists encountering tadpoles in the Si­erra Nevada pay careful attention to tadpole mouthparts and re­port any occurrences to the authors (e-mail:[email protected]). If proper permits are attained, asingle voucher should be placed in 95% ethanol and sent to theprimary author. We will maintain a website with information onthe chytrid situation in the Sierra Nevada:
