    Notes: Abstract At many beaver (Castor canadensis) sites at Allegany State Park in New York State, red maple (Acer rubrum) is the only or one of the few tree species left standing at the ponds' edges. The relative palatability of red maple (RM) was studied in three ways. (1) At seven beaver sites, the available and utilized trees were recorded and an electivity index (E) computed. Of 15 tree species, RM ranked second or fourth lowest. (2) In experiment I, RM, sugar maple (A. saccharum, SM), and quaking aspen (Populus tremuloides) logs were presented cafeteria style at 10 colonies. RM was the least preferred. (3) Bark of RM was extracted with solvents. Aspen logs were painted (experiment II) or soaked (experiment III) with this RM extract and presented to beaver cafeteria-style, along with aspen and RM controls. This treatment rendered aspen logs less palatable, indicating that a chemical factor had been transferred.

Marr and Gardner6 sprayed pups of laboratory rats with cologne and found that they later preferred cologne-smelling rats, while pups treated with methyl-salicylate became socially anosmic as adults.

    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 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 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: Zusammenfassung Bei Zusatz von Lysolecithin in einer 7–8 mM Endkonzentration zu Hirnhomogenaten erfolgt eine Vermehrung des wasserlöslichen, extrahierbaren Proteins um den Faktor 3–5. Die elektrophoretische Wanderung der Hirnproteine wird verändert. Eine wesentliche Denaturation der extrahierten Proteine durch den Lysolecithinzusatz tritt nicht ein. Als Beweis dafür wurden Messungen der enzymatischen Aktivitäten herangezogen. Die Ergebnisse der erhobenen Befunde werden in ihrer möglichen Bedeutung für die Entmarkungskrankheiten diskutiert.

    Notes: Abstract. The reformulation of geodetic measurement processes within the framework of general relativity is discussed. The metric tensor plays an important role in general relativity and has to be represented with respect to a set of appropriate charts. Almost every quantity of interest in geodetic or geophysical applications refers to a geocentric, Earth-fixed coordinate system (chart), therefore they are of great importance in geodesy and geophysics. The space–time metric with respect to an Earth-fixed chart is derived at first post-Newtonian order. The field equations determining the terrestrial gravitational field are derived and its explicit representation is outlined. The impact of the results on the modelling of geodetic measurement processes including space–time positioning scenarios as well as the high-precision gravitational field estimation is outlined.
