Mom's Day Out: Investigating The Proximate Causes Of Allomothering In Squirrel Monkeys, Amber Wright
Mom's Day Out: Investigating The Proximate Causes Of Allomothering In Squirrel Monkeys, Amber Wright
Anthropology Undergraduate Senior Theses
Allomothering, which is defined as non-material infant care, is a behavior that is found among many animal species. Although it is widely acknowledged in primate species in particular, it is not well understood. Allomaternal behavior is well documented but the proximal causes are not known. Most primate species live in groups and have intense social relations which govern every aspect of their behavior. Allomothering could then be better understood by looking at the social relationships that exist between members of a group. This research tries to better understand what causes certain females to allomother over others by looking at the …

Squirrel Monkey Pelvic Morphology And Difficult Pregnancies: It's Not All In The Hips, Lucinda Freeman
Anthropology Undergraduate Senior Theses
Researchers at the CNPRR have observed a reduction in the reproductive success of female squirrel monkeys of Bolivian origin (Saimiri boliviensis boliviensis) due to nonviable termination of their pregnancies. Difficulties with pregnancy, including dystopias and stillborn infants, seem to be a result of an extremely large fetal to mother weight ratio. This factor has led to studies of the pelvic size and shape in the Bolivian origin female squirrel monkeys. Aksel and Able (1983) devised a pelvimetry method for evaluating the bony structures of the pelvis in order to predict perinatal outcome. This thesis will apply the pelvimetry methods of …
