The mean number of oviductal eggs was somewhat higher than the mean previously reported for this frog from Arkansas. The number of eggs per mass oviposited in Illinois was about half the number reported for Arkansas females. The eastern woodrat, a state-endangered species, is a generalist herbivore that depends on cached food during part of the year. We identified seasonal variation in the diet of woodrats at Pine Hills, Union County, Illinois, based on analysis of fecal pellets, and determined if they consumed forage in proportion to its availability in the habitat. Woodrats did not consume forage in proportion to availability for any season during 1995.
Resource caching decisions of woodrats depend on nutrient content and perishability.
Woodrats appeared to ration cached resources so as not to be left with poor foods at the end of the cache-dependent period.
