Abstract |
An understanding of patterns of leadership during grazing movements is important where the management of grazing cattle is concerned. This paper describes the leadership displayed by grazing cattle by recording the spatial relationship (grazing style) among herd members as the group progressed slowly through a field. Grazing style was divided into “A”, “B” and “C”, meaning following, independence and leading, respectively. The results revealed the following features: (1) the frequency distributions of grazing style and grazing formation used by the herd varied with the seasons; (2) the individual animal variation in grazing style did not fundamentally change with the seasons; (3) there was negative linear correlation between Styles A and C and between Styles A and B. The more any cow followed the grazing movement, the less likely it was to lead the grazing movement or to be independent. Styles C and B tended to be positively related; (4) high, medium and low ranking animals in social dominance showed tendencies to behave in Styles C, A and B, respectively; (5) grazing style and weight gain were not clearly related; (6) the cows that tended to lead, be independent or follow less, tended to get out of their paddocks. The observations suggested (1) that the leader-follower-independent relationship, although modified in each season, did not vary fundamentally, (2) that the active movement of high ranking animals and the independent movement of low ranking animals governed the voluntary formation in grazing, and (3) that as grazing cattle that behaved in a single group and did not escape from their paddock were much easier to manage, the grazing style that expressed these characteristics was one of the significant indices for management of grazing cattle. |

Abstract |
Preconditioning experience with the unconditional stimulus (UCS) retards subsequent excitatory conditioning. Three experiments demonstrated that this UCS retardation effect is attenuated by associative manipulations of contextual stimuli of the UCS preexposure environment. The UCS retardation effect was reduced by (a) altering contextual stimuli between preexposure and conditioning (Experiment 1), (b) latently inhibiting contextual stimuli prior to UCS preexposure (Experiment 2), and (c) extinguishing contextual stimuli subsequent to UCS preexposure (Experiment 3). Although UCS preexposure retarded excitatory conditioning, the results of Experiment 4 demonstrated that UCS preexposure facilitated inhibitory conditioning. These results indicate that an association between contextual stimuli and the preexposed UCS contributes to the effects of preconditioning UCS experience on subsequent learning. |

Abstract |
The African wild ass is endangered. Its habitat is a drought-stricken war zone; its flesh is eaten and is believed to cure hepatitis; it is eagerly sought by dealers and collectors. The author, Chief Curator at Israel's Hai-Bar reserve, examines the problems hindering the conservation of this animal and explains why it is urgently necessary to list it on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora at its meeting in April 1983. |
