Response To Water

The dwarf hamsters Phodopus campbelli and P. sungorus are found in semi-arid areas of Siberia and northern Mongolia, but habitat and diet differences suggest species differences in water regulatory efficiency. These differences were investigated by examining the effect of moderate water restriction (50% of ad libitum consumption) on solitary dams and on their reproductive success. In response to water restriction, P. sungorus dams lost less body mass than P. campbelli dams, and despite similar litter sizes, P. sungorus produced heavier litters and pups than P. campbelli, indicating that P. sungorus pups were larger. These results suggest that P. sungorus is more tolerant of water restriction than P. campbelli. In a second experiment the possibility that paternal care may mitigate the effects of water restriction was examined by leaving the mated pair together throughout lactation. Pairing reduced mass loss by P. campbelli dams and increased the proportion of large P. campbelli pups at weaning, but had no effect on these measures in P. sungorus, eliminating interspecific differences in responses to water restriction. Results suggest that biparental care may be a facultative response to environmental stress in P. campbelli.
