Abstract
The durations of logging operations may be regarded as critical periods in which primates will be required to make rapid adjustments in behavioral patterns. Primates are extremely difficult to observe during logging operations, but their behavioral response may be interpreted from analysis of calling patterns. In Hylobates lar,increased calling frequencies of groups may be indicative of intruder pressure, as may reduced calling frequencies of animals which are avoiding confrontation with conspecifics or avoiding detection by loggers. In Presbytis melalophosthe function of calling is to mediate intergroup avoidance, such that differential calling frequencies would not be expected. Where reduction in calling occurs it is probably directed toward concealment from loggers. Groups do not emigrate from active logging areas and movement outside of established territories occurs only to a very limited extent.
