Resumen:
We analyzed
immature-to-mother social distance (juveniles and nonnursing infants) in two
Mexican mantled howler monkey (Alouatta palliata) troops inhabiting a tropical
rainforest fragment (40 ha) at Los Tuxtlas, Veracruz, Mexico. During July and
August of 2000 and 2001 we applied an instantaneous sampling method (317 hr) to
record the behaviors of the immatures and their mothers, as well as distances (ordinal
scale) between immatures and their mothers (IMD), and between immatures and
nonmother individuals (INMD). Immatures were generally less than 5 m away from
any individual of the troop. Social distance was influenced by the different
behaviors of both mothers and immatures, with the shortest distances occurring
during rest (IMD < 5 m in 94% of all instantaneous samples) and the longest
during exploration (21% ≥ 10 m) and play (26 % ≥ 10 m). When IMD increased, we
found a higher percentage of records < 5 m to other individuals,
particularly with the probable father. When the variation in distance to the
mother and to other individuals in the troop was considered, the immature
animals distance to other troop members depended on the immatures age and type
of behavior. Overall, these results suggest that in this low-activity species
the development of the immature is associated with a complex set of
relationships with other troop members.
