Asymmetries in postural control and locomotion in chimpanzees (Pan troglodytes)

Article Abstract:

The degree of asymmetry in four behaviors related to locomotion, namely walking, ascending, descending and brachiating, and four behaviors associated with posture, namely sitting, lying, hanging and changing postures, are studied in a group of chimpanzees. Few subjects show individual preferences, but the observed trends and correlations in the behaviors highlight the importance of postural and locomotion factors in motor asymmetry in primates.

Quantifying remaining forested habitat within the historic distribution of the cotton-top tamarin (Saguinus oedipus) in Colombia: Implications for long-term conservation

Article Abstract:

Landsat Thematic Mapper (TM) data were used in a study to examine the amount of habitat loss and fragmentation that has occurred within the historic distribution of the cotton-top tamarin (Saguinus oedipus) in Colombia. The results of the study provide valuable information to assist in the long-term development of effective conservation strategies for this endangered primate.

Effect of the enclosure on carriers' body weight loss in the cotton-top Tamarin (Saguinus oedipus)

Article Abstract:

An attempt is made to study the body weight changes in adult and subadult individuals from eight large groups for 9 weeks after the birth of infants. Results indicate that reproductive males lost more weight in the big indoor/outdoor enclosures than in the small indoor ones, as did male adult helpers and female adult helpers.
