Evolutionary trends in thermal metabolic acclimation patterns in Northean and southern hemisphere crustaceans

Estudos foram conduzidos em caranguejos ecopépodes pertencentes á mesma espécie ou espécies relacionadas dos hemisférios norte e sul, para determinar se estas espécies desenvolveram os mesmos tipos de resposta fisiológica em relação à temperatura nos extremos de sua distribuição geográfica nos dois hemisférios, ou se ao invés diferentes estratégias funcionais foram desenvolvidas

Children’s coping with in vivo peer rejection: An experimental investigation

We examined children's behavioral coping in response to an in vivo peer rejection manipulation. Participants (N=186) ranging between 10 and 13 years of age, played a computer game based on the television show Survivor and were randomized to either peer rejection (i.e., being voted out of the game) or non-rejection control. During a five-min. post-feedback waiting period children's use of several behavioral coping strategies was assessed. Rejection elicited a marked shift toward more negative affect, but higher levels of perceived social competence attenuated the negative mood shift. Children higher in depressive symptoms were more likely to engage in passive and avoidant coping behavior. Types of coping were largely unaffected by gender and perceived social competence. Implications are discussed. © 2006 Springer Science+Business Media, LLC
