    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.

    The “deer lactone” (1978)
    Springer
    Journal of chemical ecology 4 (1978), S. 247-256 
    Details
    ISSN: 1573-1561
    Keywords: Black-tailed deer ; “deer lactone” ; discrimination ; enantiomers ; (Z)-4-hydroxy-6-dodecenoic acid lactone ; Odocoileus hemionus columbianus ; lactone

    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.

    Subspecies specificity of response to a mammalian social odor (1975)
    Springer

    ISSN: 1573-1561
    Keywords: deer ; mammals ; odor preference ; odor specificity ; olfactory discrimination ; pheromone ; sexual isolation ; social odor ; tarsal scent

    Topics: Biology , Chemistry and Pharmacology
    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.

    Response to a mammalian pheromone and its geometric isomer (1976)
    Springer
    Journal of chemical ecology 2 (1976), S. 389-398

    ISSN: 1573-1561
    Keywords: Black-tailed deer ; geometric isomers ; (E) and (Z)-4-hydroxy-6-dodecenoic acid lactone ; mammals ; Odocoileus hemionus columbianus ; olfactory discrimination ; pheromones ; stereoisomers ; tarsal scent

    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.

    Petrological significance of prograde homogenization of growth zoning in garnet: an example from the Llano Uplift (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of metamorphic geology 15 (1997), S. 0 
    Details
    ISSN: 1525-1314
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: In the Llano Uplift of central Texas (USA), prograde homogenization of garnet growth zoning took place during moderate-to high-pressure dynamothermal metamorphism over a narrow temperature range near the transition from the amphibolite to the granulite facies. This subtle record of early dynamothermal metamorphism survived subsequent static metamorphism at low pressures in the middle-amphibolite facies, despite the destruction of most high-pressure mineral assemblages that originated in the early metamorphic episode. Geographically systematic variations in the degree of homogenization indicate that the uplift as a whole underwent high-pressure metamorphism, in accord with emerging tectonic models for the mid-Proterozoic evolution of the southern margin of the North American continent.

    HOW INCOME INEQUALITY CHANGED IN GERMANY FOLLOWING REUNIFICATION: AN EMPIRICAL ANALYSIS USING DECOMPOSABLE INEQUALITY MEASURES (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Review of income and wealth 42 (1996), S. 0 
    Details
    ISSN: 1475-4991
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Economics
    Notes: This paper analyzes how inequality in Before and After Government income has changed in Germany since reunification using the 1990 through 1992 waves of the German Socio-Economic Panel. A Theil decomposable inequality index is used to measure inequality in Germany and in its eastern and western states. Massive public transfers from west to east have narrowed the east-west income gap, substantially offset the rise in income inequality from private sources, and lowered overall inequality in the western states. The net result of this policy has been a drop in After Government income inequality in Germany between 1990 and 1992.

    Using Panel Data on Income Satisfaction to Estimate Equivalence Scale Elasticity (2003)
    Oxford, UK and Boston, USA : Blackwell Publishing Ltd
    Review of income and wealth 49 (2003), S. 0 
    Details
    ISSN: 1475-4991
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Economics
    Notes: In this paper, the equivalence scale elasticity will be estimated by using individual panel data on income satisfaction from the German Socio-Economic Panel Study (GSOEP). Satisfaction or happiness data have been more frequently used by economists in recent years to analyze individual well-being. The approach differs from other subjective approaches as respondents are requested to evaluate current income rather than income in hypothetical situations. The estimated scale elasticity is higher compared to those from other subjective approaches based on German data. In addition, panel data enable different scale use by the respondents to be controlled. It can be shown that elasticity decreases when unobserved fixed-effects are controlled for.

    A COMPARISON OF ALTERNATIVE MEASURES OF ECONOMIC WELL-BEING FOR GERMANY AND THE UNITED STATES (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Review of income and wealth 43 (1997), S. 0 
    Details

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Economics
    Notes: This paper, using six waves of data (1984-89) from the United States Panel Study of Income Dynamics (PSID) and the German Socio-Economic Panel (GSOEP), compares economic well-being using single year income, multi-year income, and wealth as measures. We find inequality to be greater in the United States than in Germany regardless of the measure used. However, the relative degree of inequality varies across measures. When we disaggregate our data by age and gender categories, in general we find greater inequality in the United States, but wealth inequality among older Germans is greater than it is among older Americans.
