A robust relationship has been established between psychopathy and violence, and psychopathy is considered essential in the process of violence risk assessment. This study presents data on a patient sample from a forensic psychiatric unit in Denmark. All patients were assessed for psychopathy using the Psychopathy Checklist Screening Version (PCL:SV) and the Comprehensive Assessment of Psychopathic Personality (CAPP). After a follow-up period of 5.7 years, recidivism outcomes were obtained from the Danish National Crime Register. Both psychopathy measures were related to a more severe and versatile criminal career as well as to violent recidivism. Overall, the predictive accuracy of violent recidivism of the two measures was good, and no significant difference was found in terms of predictability. The newly developed CAPP could be a promising clinical risk management tool in terms of its comprehensiveness. Its validity needs to be further explored, but at least its ability to predict violence similar to the PCL:SV is supported by the present study.

We allowed seven willow tits, Parus montanus, to store and retrieve with retention intervals of 1, 7, 21 and 56 days, in four experimental rooms. Retrieval success decreased over time, indicating a decaying memory for cache locations. Compared to what could be expected by chance, retrieval success was better after all retention intervals. Our results suggest that - after the longer retention intervals - this might depend on preferences for certain types of caching locations rather than memory. If both general and individual preferences are controlled for, birds retrieved significantly better than expected one and seven days after storing, but not later than that.

We studied feeding behaviour by twig browsing goats in relation to two types of spines 35 of Acacia tortilis using experimental manipulation of the occurrence of spines.
