Table 1.

Some examples of peak energy intakes of non-domesticated small (less than 1 kg) mammals at different phases of the reproduction cycle. LS is litter size. Under P this is litter size at birth; under L, this is litter size at weaning. Where original paper does not state which, it is entered under both. Status: NB, non-breeding; P, pregnant; L, lactating. × NB is the intake expressed as a multiple of the non-breeding intake. In all cases (except *), the animals were studied in the laboratory at standard room temperatures (21–24°C) with ad libitum access to food. ** animals kept at 5°C * animals kept at 10°C. In some cases, the original data were quoted relative to body mass0.75, and in these instances the actual intakes have been recalculated using the cited body mass. In other papers, only mass of food ingested is cited and these have been converted assuming a dry mass energy content for the food of 20.9 kJ g−1, unless a different value was cited in the paper. In yet other studies, average daily metabolic rate (ADMR) is quoted. I have converted this to energy intake assuming a digestive efficiency of 80%. Genera: Rodents C. = Clethrionomys, P. = Peromyscus, M. = Microtus, Me. = Meriones, A. = Acomys, Ca. = Cavia, S. = Sigmodon, Sc. = Sciurus. Insectivores, S. = Sorex, C. = Crocidura, Ec. = Echinops, E. = Erinaceus. Bats P. = Plecotus, T. = Tadarida, E. = Eptesicus, M. = Myotis, R. = Rousettus. ^ estimates relative to NB calculated using the NB in reference 7. $ estimates expressed as difference to unquoted NB level in original ms.
