Experiments on the feeding of frogs are not numerous, although much dissection work has been done to determine stomach contents. One of the most complete records of the diet of an individual frog appears in D. C. Beard's "American Boy's Handy Book." He itemizes the daily diet of a frog, probably Rana catesbeiana, from May 14 to November 17. During this period, the frog consumed 12 beetles, 9 mice, 1 frog, 3 crawfish, 1 bat, two thirds of a perch, and, in addition, tackled a young alligator 113… Expand

The Food and Food Habits of Blanchard's Cricket Frog, Acris crepitans blanchardi (Amphibia, Anura, Hylidae), in Iowa
Stomach contents of 218 Blanchard's cricket frogs were analyzed relative to frog size, reproductive status, size of fat bodies, sex, and date. Food consumption was found to be greater in largerExpand
A Study of the Western Chorus Frog, Pseudacris triseriata, in Vigo County, Indiana
TLDR
An ecological study was conducted on the Western Chorus Frog, Pseudacris triseriata, at Terre Haute, Vigo County, Indiana, between 1963 and 1969, and described the development of tadpoles, froglets, and young individuals. Expand
GASTRIC DIGESTION IN THE LOWER VERTEBRATES
TLDR
It is concluded that the absence of a stomach from the Holocephali, the Dipnoi and certain Teleostei is likely to be a secondary rather than a primitive condition, and it is emphasized that a clear-cut reciprocity between sympathetic and parasympathetic systems may be lacking in the lower vertebrates.

MOULTING IN THE ANURA: THE NORMAL MOULTING CYCLE OF BUFO REGULARIS REUSS
TLDR
The frequency of moulting is not influenced by size, age or feeding, nor does there appear to be any difference in this regard between the sexes; any seasonal variation is slight. Expand
Net neutral effects of a generalist vertebrate predator on seed production result from simultaneous suppression of plant antagonists and mutualists
TLDR
It is suggested that simultaneously examining the effects of predators on plant mutualists and antagonists is necessary to fully understand the roles of generalist predators in natural food webs. Expand
GASTRIC DIGESTION IN THE LOWER VERTEBRATES
True gastric digestion, involving the action of pepsin, appears to be found in animals only in the Chordata, and in this group, at the present day, only from the Pisces upwards. It is suggested thatExpand
