    Species, population and individual specific odors in urine of mole rats (Spalax ehrenbergi) detected by laboratory rats (1996)
    Springer
    Chemoecology 7 (1996), S. 107-111 
    Details
    ISSN: 1423-0445
    Keywords: chemical communication ; characteristic odors ; subterranean mole rats ; mammalia ; Spalax ehrenbergi

    Topics: Biology
    Notes: Summary Urine odors from 4 species of blind subterranean mole rats belonging to theSpalax ehrenbergi superspecies in Israel were evaluated to determine whether there were discriminable differences in the odors that were specific to different individuals, populations, and species of mole rats. Trained laboratory rats assessed these differences in an automated olfactometer using an operant conditioning paradigm. They demonstrated the discriminability of the urine odors in the 3 categories by their correct responses in generalization trials. These characteristic species, population and individual odors may provide these solitary, territorial and blind rodents a means for diverse chemical communication in spacing behavior, reproduction, species isolation and speciation.

    Stability of chemical communicants in urine: Individual identity and age of sample (1983)
    Springer
    Journal of chemical ecology 9 (1983), S. 235-245 
    Details
    ISSN: 1573-1561
    Keywords: Chemical communication ; guinea pig ; Cavia porcellus ; individuality ; odors ; urine ; stability of odors

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Male guinea pigs differentiated between fresh female urine and the same urine aged for 3 hr. Additionally, when tested with an habituation paradigm, they exhibited no evidence of recognizing fresh urine and the same urine aged for 3 hr as coming from the same animal. Males preferred the urine of a strange male compared to their own urine when the urine was fresh, aged for 2 hr or aged for 3 days, but not when the urine was aged for 8 days. These results suggest that the urinary cues of individual identity are not stable and that males have learned to recognize the modifications of their own urine which result from aging. In addition, it was found that changes in urine following aging make it possible for male guinea pigs to discriminate between urine samples aged for different amounts of time.

    Perineal scent gland of wild and domestic guinea pigs (1979)
    Springer
    Journal of chemical ecology 5 (1979), S. 737-751 
    Details
    ISSN: 1573-1561
    Keywords: Chemical communication ; guinea pig ; skin secretion ; scent mark ; C. aperea ; C. porcellus
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Wild and domestic male guinea pigs (Cavia aperea andCavia porcellus) prefer the perineal secretion from males of the same species to that of males of the other species. Gas chromatographic-mass spectroscopic analyses of the volatile components of the secretions show complex mixtures comprised primarily of fatty acids, alcohols, and ketones. Inter-species differences in the composition of the volatiles are evident. The possible role of bacteria in odor production is discussed.

    Syn- andanti-phenylacetaldehyde oxime two novel testosterone-dependent mammalian metabolites (1977)
    Springer
    Journal of chemical ecology 3 (1977), S. 309-319 
    Details
    ISSN: 1573-1561
    Keywords: chemical communication ; phenylalanine metabolism ; guinea pig urinary metabolites ; phenylacetaldehyde oxime
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Domestic guinea pigs having high levels of circulating testosterone (i.e., males and castrate males receiving testosterone propionate injections) excrete in their urine equal amounts of both thesyn andanti isomers of phenylacetaldehyde oxime, while those guinea pigs having low testosterone titers (i.e., females, castrate males, and juveniles) excrete neither. These aldoximes were also detected in the urine of wild male guinea pigs. Radiolabeling studies in the domestic guinea pigs strongly suggest that these aldoximes are derived from phenylalanine. To our knowledge this is the first observation and isolation of phenylacetaldehyde oxime from a mammalian source. The significance of these components in phenylalanine metabolism as well as in guinea pig chemical communication is discussed.
