Field experiments are required to determine the causes of the patterns identified in this report and their potential threats to the internal validity of field studies on mantled howlers. The literature on biotelemetry suggests that radio collars are likely to have deleterious effects on animals when a radio collar exceeds 5% of body weight - "the 5% rule" - (Cooke et al., 2004; Neubaum et al., 2005). Because all adult females in Group 12 wore identification collars and tags (Jones, 1980), however, a partial control was incorporated in this research (Gauthier-Clerc et al., 2004). Ultimately, the benefits of using transmitter collars must be weighed against the costs (Cooke et al., 2004), including the important issues of scientific significance, research ethics, and animal welfare.
