Communal Rearing

AbstractThe Callitrichidae (marmosets and tamarins) typically produce twins, and have communal rearing systems in which all group members help care for the infants. It has been hypothesised that helpers benefit in some way from assisting in infant care. If so, then competition to carry infants would be predicted. This was tested in a study of 14 litters of captive cotton-top tamarins (Saguinus oedipus). All occurrences of infant transfers (movements of infants from one caretaker to another) were recorded from birth to 12 weeks. Individuals in larger groups were less likely to reject infants, more likely to actively take infants, more likely to resist attempts by others to take, and more likely to intervene in transfers, suggesting increased competition to carry in large groups. Singletons were rejected less than twin infants, again suggesting the existence of competition amongst caretakers. Mothers rejected infants more frequently than fathers; young tamarins rejected infants more than older tamarins. There was evidence that carrying by juvenile siblings and by adult daughters was limited by other group members. There was evidence that adult sons and sub-adult sons and daughters competed most strongly, and were more likely to attempt to limit carrying by other group members. These results were interpreted in the light of hypotheses suggesting that the benefits to be gained from helping may differ amongst age-sex classes.

Saguinus Oedipus Oedipus

From November 1976 to February 1979 a total of 8 litters were born to 6 females. Of the 14 infants, 10 were successfully reared by their parents. Housing, nutrition, a balance between environmental stability and stimulation, and female multiparity are seen as factors contributing to the breeding success of this colony. A controlled male and female pairing programme provided information on mating behaviour and gestation length. One gestation of at least 166 days was observed, longer than that of the common marmoset.

Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.
