Home-range size and use and territorial behavior in the common marmoset,Callithrix jacchus jacchus, at the tapacura field station, recife, Brazil
Data were obtained both from observation and by radiolocation on the size and use of the home range of the common marmoset, Callithrix jacchus jacchus.Ranges were small compared to those of other callitrichids, varying between 0.72 to 1.62 ha, and a high proportion of the home range was used each day. The marmosets showed territorial behavior, defending an area almost equivalent to the home range. Despite this, mating between animals belonging to neighboring groups was seen. Correlations between the use of the home range and some environmental variables showed little consistency between two groups which occupied ranges of differing resource density, and their activity patterns, as measured by movement through their ranges, were also different. Possible reasons for these inconsistencies are discussed.
