  • Relationships between diurnal adrenocortical activity, children’s attachment security and mothers’ attachment representations

    Open AccessLisa Roque, Manuela Veríssimo et al.ARTICLEAnálise Psicológica2015

    This study investigated the relationship between diurnal adrenocortical activity and attachment quality (children’s secure base behaviours and mothers’ attachment representations). Forty-two children ranging in age from 18 to 26 months of age and their mothers participated in this study. Children and mothers’ saliva samples were collected on two consecutive days (Saturday and Sunday), three times per day: awakening; 20m after awakening; bedtime. …

  • Metabolic costs of aggressive behaviour in the Siamese fighting fish,Betta splendens

    Open AccessNídia Castro, Albert F H Ros et al.ARTICLEAggressive Behavior2006References: 30

    Aggressive conflicts between males are often resolved by means of multiple ritualized agonistic displays without damaging escalation. Apparently, in such cases by using those displays opponents exchange important motivational and physical information on which they base a decision to stay or leave the interaction. In the Siamese fighting fish, the time spent spreading the dorsal fin and erecting the gill coverts predicts who will be the winner or …

  • Maternal aggression during the mouthbrooding cycle in the Cichlid fish,Oreochromis mossambicus

    Open AccessG A Oliveira, Rui F Oliveira et al.ARTICLEAggressive Behavior1998References: 34

    Maternal aggression was studied in Oreochromis mossambicus during the mouthbrooding cycle. Brooding females were observed in heterosexual captive groups, and their agonistic interactions and behavioural activities were registered. Brooding females were classified into three classes according to the developmental stage of the brood they were incubating: phase 1, brooding eggs; phase 2, brooding fry with yolk-sac; phase 3, brooding fry with exogene…

  • On the (in)stability of dominance hierarchies in the cichlid fishOreochromis mossambicus

    Open AccessG A Oliveira, Rui F Oliveira et al.ARTICLEAggressive Behavior1996References: 35

    Dominance hierarchies were studied during 8 weeks in eight heterosexual captive groups of Oreochromis mossambicus at the onset of sexual maturity. Linearity was assessed for each group on a weekly basis based on the Landau's index (h) and on the procedure described by Appleby [Appleby MC (1983): Animal Behaviour 31:600–608]. Week-to-week stability of the hierarchical structures was measured using the Burk's stability index (b) and Spearman rank c…
