    Notes: Abstract Urine of the black-tailed deer is the source of the “deer lactone,” which is deposited on the tarsal gland tufts by “rub-urination.” The enantiomer composition of the lactone from the urine of the female is 89(R)-(−)/11(S)-(+). Responses by deer were strongest toward the synthetic racemic lactone in the social test and toward the natural lactone in the choice test. In both tests, the (−)- lactone released slightly stronger responses than its enantiomer.

    Notes: Abstract Two subspecies of deer, black-tailed deer (Odocoileus hemionus columbianus) and Rocky Mountain mule deer (O. h. hemionus) were exposed to the tarsal scents of both subspecies in a social setting. The scent was sprayed on one individual in a group. The responses, consisting of sniffing, licking, and following, were stronger to each subspecies' own tarsal scent. This discrimination may be important for sexual isolation in areas where the ranges of the two species overlap.

    Notes: Abstract Black-tailed deer (Odocoileus hemionus columbianus) discriminate between the geometric isomers of a lactone used as a pheromone by the species. They react strongly to (Z)-4-hydroxy-6-dodeceonic acid lactone, which occurs in their tarsal scent, but the response to theE isomer did not differ from the response to the solvent. The isomers were applied to one member of a group of freely interacting deer, and the sniffing, licking, and following responses were recorded. The synthesis of the geometric isomers of the lactone is described.

    Notes: Abstract Male black-tailed deer were exposed to conspecific urine samples monthly for one year. The urine samples tested were from adult male, nonestrous female, estrous female, male fawn, and female fawn. The urine was offered with and without a wire screen cover; Flehmen occurred only when direct mouth and/or tongue contact with the urine was possible. The frequency of Flehmen varied seasonally, and urine from adults released more Flehmen than urine from fawns. But there was no difference in Flehmen frequency in response to urine from adult males or estrous or nonestrous females, when presented out of context, although in a natural situation males respond more to urinating females than males.

    Notes: Abstract Behavior observations in European reindeer (Rangifer tarandus) showed a high frequency of sniffing the tails of conspecifics. A caudal gland was found, and it is the largest skin gland inRangifer. Behavioral contexts of tail sniffing, the histology of the gland, and some aspects of the composition of the volatiles in the gland's secretion are described.

    Notes: Abstract Flehmen (or “lipcurl”) is a response of male mammals primarily to female urine, performed primarily during the reproductive season. To elucidate the components of female urine that release the Flehmen, urine of black-tailed deer (Odocoileus hemionus columbianus) was fractionated, and the fractions were presented to captive male conspecifics during three rutting seasons. The active principle (one or more compounds) is watersoluble, of low volatility, not readily extractable with organic solvents, and between 200 and 12,000 daltons in molecular weight. Several urine components were identified, but none of these showed activity.
