    Notes: Abstract In one study, using a habituation procedure, male South American cavies,Cavia aperea, distinguished individual differences in odors collected from three sources: perineal gland secretions, urine, and supracaudal gland secretions. In a second study, male cavies spent more noninvestigatory time and rested more on the side of a cage containing the odor of a familiar subordinate male as compared to the cage side containing the odor of a familiar dominant male. Since the odor source was a glass plate which had been left in the home cage of the donor males for three days, the actual odorous cue to which the test males responded is not known. These studies demonstrate that male cavies distinguish odors of individuals, that individual differences in odors are found in at least three different sources, and that cavies use chemical cues to distinguish between known individuals.

    Notes: Abstract We examined voluntary NaCl intakes of five mouse strains: NZB/B1NJ, SM/J, 129/J, C57BL/6ByJ, and CBA/J. Using two-bottle tests with water as one choice, the mice were offered series of progressively increasing or progressively decreasing NaCl concentrations (37.5–600 mMNaCl in 48-h tests), then 300 mMNaCl for 6 days and 75 mMNaCl for 8 days. Low concentrations of NaCl were more avidly accepted by mice given the increasing rather than the decreasing series. However, irrespective of the test order, test duration, or how the results were expressed (i.e., as raw intakes, intakes corrected for body weights, or preferences), the NZB/B1NJ mice always had higher NaCl acceptance than did the CBA/J mice. The SM/J, 129/J, and C57BL/6ByJ strains were intermediate between the NZB/B1NJ and the CBA/J strains, but their distributions varied from concentration to concentration. Low (≤150 mM) NaCl concentrations were avoided by the C57BL/6ByJ and CBA/J mice, but the NZB/B1NJ, SM/J and 129/J mice either preferred or were indifferent to them. High (≥300 mM) NaCl concentrations were strongly avoided by all mice, except for the NZB/B1NJ strain. It is suggested that separate genes underlie the strain differences in acceptance of dilute and concentrated NaCl solutions.
