Abstract |
Feral horses (Equus caballus) in the Venezuelan savannas (Ilanos) formed bands of 3-35 individuals; mean group size varied between 15 and 21. Some bands had up to three adult males, and there was a positive correlation between the number of males and the number of females in bands. Adult males also were seen solitary or formed bachelor groups. One association of three females was observed for 3 months. We noted a correlation between number of females in bands and number of foals per female born during our study (January-July 1992). The advantages of being in larger groups were unclear, because natural predators were rare. Perhaps females in larger groups have more time available for foraging due to reduced individual vigilance or that larger groups live in better-quality home ranges. |

Abstract |
A two-compartment maze providing a single left- or right-side choice was used to test maze-learning ability in 37 quarter horses. Preference for left- or right-side choices varied among the horses. The taller and thinner horses tended to go left. The horses showed learning ability based on decreases in latency and decreases in errors as trials progressed in a right-side escape pattern. The rate of learning an opposite escape pattern, left-side escape, was faster but owing to the large number of errors occurring when the pattern was reversed, the level of errors did not reduce to a level comparable to that achieved in the right-side escape pattern until adverse stimuli were presented in the blind compartment. Heavier horses took longer to escape from the maze when adverse stimuli were presented. Differences in learning ability for horses fed various levels of dietary protein were not consistent. N1 - |

Abstract |
The oxidation-reduction reaction of horse heart cytochrome c and cytochrome c (552, Thermus thermophilus), which is highly thermoresistant, was studied by temperature-jump method. Ferrohexacyanide was used as reductant. Thermodynamic and activation parameters of the reaction obtained for both cytochromes were compared with each other. The results of this showed that (1) the redox potential of cytochrome c-552,+0.19 V, is markedly less than that of horse heart cytochrome c. (2) [up triangle, open]Hox++ of cytochrome c-552 is considerably lower than that of horse heart cytochrome c. (3) [up triangle, open]Hox++ and [up triangle, open]Sred++ of cytoochrome c-552 are more negative than those of horse heart cytochrome c. (4) kred of cytochrome c-552 is much lower than that of horse heart cytochrome c at room temperature. |
