The effect of the presence of a con-specific in the temporal organization of food hoarding was studied in two varieties of Syrian hamster (Mesocricetus auratus): golden and long-haired. Four male hamsters of each variety were used. Their foraging behavior was observed during four individual and four shared trials in which animals were not competing for the same food source or territory. During individual trials, long-haired hamsters consumed food items directly from the food source, transporting and hoarding only remaining pieces. During shared trials, the long-haired variety hoarded food items before consumption, and increased the duration of hoarding trips, food handling in the storage, and cache size. Golden hamsters maintained the same temporal organization of hoarding behavior (i.e., hoarding food items before consumption) throughout both individual and shared trials. However, the golden variety increased handling time at the food source and decreased the duration of hoarding trips, the latency of hoarding and storing size throughout the shared trials. In Syrian hamsters, the presence of a con-specific may signal high probability of food source depletion suggesting that social pressures over food availability might facilitate hoarding behavior. Further studies are required to evaluate cost-benefit balance of food hoarding and the role of cache pilferage in this species.

Bovet claims that Smith et al. (D.W. Smith, R.O. Peterson, T.D. Drummer, and D.S. Sheputis, 1991. Can. J. Zool. 69: 2178–2182) and Dyck and MacArthur (A.P. Dyck and R.A. MacArthur, 1992. Can. J. Zool. 70: 1668–1672) analyzed their data on activity and body temperature of beavers (Castor canadensis) incorrectly because they ignored the likelihood that northern beavers in winter have activity rhythms with periods >24 h. The analysis by Smith et al. was in fact appropriate for demonstrating seasonal changes in body temperature and its correlation with activity. These are important issues because researchers have obtained conflicting results and because seasonal changes in activity and body temperature have implications for colony energetics in the context of food-hoarding behavior and social organization.

AbstractWhen an environment is uncertain, humans and other animals benefit from preparing for and attempting to predict potential outcomes. People respond to uncertainty both by conserving mental energy on tasks unrelated to the source of the uncertainty and by increasing their attentiveness to information related to the uncertainty. This mental hoarding and foraging allow people to prepare in uncertain situations.
