EFFECT OF IONIZING RADIATION AND OTHER ENVIRONMENTAL FACTORS ON BREEDING BEHAVIOR, ACTIVITY PATTERNS AND MOVEMENTS OF SELECTED VERTEBRATES

摘要

For any two animals, three major factors limit communication. These are (1) whether appropriate signal mechanisms are available to them, (2) whether the animals are motivated to communicate, and (3) whether their movements and locations are such that signal can pass between them. In this study, signal mechanisms and motivation were not considered as variables, but the role of animal movement in limiting communication was. A computer simulation study of amounts of communica¬tion which occur in red fox (Vulpes vulppes) dyads when various means of signalling arc used, and when the animals move about and signal with various emission intensities and at various time intervals is reported.
