The study investigated whether there were associations between how much adolescents slept per night and how much aggressive and antisocial behavior they displayed and were exposed to. Two hundred thirty-eight adolescents (122 females, 116 males; mean age = 15.5 years, SD = 2.0) from Ejigbo, Lagos, Nigeria, participated in the study, which was conducted with a paper-and-pencil questionnaire. It was found that the total sleeping time of the adolescents correlated negatively with five scales measuring Adult Aggression, Sibling Aggression, Domestic Violence, Parental Negativity, and Antisocial Behavior. Thus, the less the adolescents slept, the more they were exposed to aggression, and they also themselves behaved more aggressively and antisocially. Participants living in overcrowded conditions slept less than others.

SummaryFrom 2000–2008 we used transmitting video cameras to document the breeding biology of the endangered Bearded Vulture in the Pyrenees (NE Spain), focusing the study on sibling aggression. Our goals were to study the feasibility of rescuing second-hatched chicks for conservation purposes in this species that shows obligate brood reduction. The age at which the second chick died varied between 4 and 9 days (n= 5). Prey items delivered per hour were not related to the survival time of the second chick or the aggressiveness of the first-hatched chick towards their sibling. Although sibling aggression generally began on day 1 after hatching, in two nests supplemented with food, aggression was delayed until the second and third day after hatching and the second chick survived for nine days. Our results on the death of the second chick and the test involving the rescuing of a second-hatched chick aged five days, suggest that the recommended age for intervention should be between 3 and 6 days, with 4–5 days probably being the optimal age for the rescue.

Abstract Sibling aggression occurs in a wide variety of asynchronously hatching bird species. In some, fights among siblings lead inevitably to death, in which case the benefits of winning are clear. In species where sibling aggression is common but usually not fatal, the benefits gained by winning and the methods used to achieve them are less obvious. In a Texas colony of Cattle Egrets (Bubulcus ibis), sibling aggression was frequent but siblicide rare. Parents rarely interfered with fights. Last-hatched chicks lost more fights and received less food than their elder siblings. Fighting limited the losers' immediate access to food and contributed to the senior sib's ability to monopolize boluses. These results are consistent with the hypothesis that monopolizable food can act as both a proximate and ultimate cause of sibling aggression. The main effect of sibling aggression lay in depressing food supplies to last-hatched chicks. First- and second-hatched sibs accrued roughly equal feeding advantages.
