The Tailed Frog Ascaphus truei, the only species in the
family Ascaphidae found outside New Zealand, is a common inhabitant
of the mountain streams of the Northwestern United States and
British Columbia. The anatomical peculiarities of this primitive
anuran have been investigated, but no literature is available on the
digenetic...
Description of anuran larvae with the use of staging tables is
a common practice in the study of frog life-histories, but there has
been no previous description or table of Ascaphus larvae. In comparing
Ascaphus larvae to a simplified staging table for anurans it
was found that these larvae vary...
Electron microscopic, histochemical and thin-layer chromatographic
techniques have been used to study some cytological changes
associated with seasonal lipid deposition in the liver of Ascaphus.
Histochemical and chromatographic information has shown that unsaturated triglycerides occur in great quantities in the liver of pre-ovulatory females and may serve as a solvent...
