Trioecy, the co-occurrence of males, females and hermaphrodites in natural populations, is a relatively common sexual system in plants, but is rare and poorly understood in animals. Previously, the marine mussel, Semimytilus algosus , has been described as a simultaneous hermaphrodite and there are reports of unisex animals in the wild. Here, we confirm trioecy in this bivalve, the first report of trioecy in the phylum Mollusca. The consistent sex ratios across all populations suggest that the sexual system is stable in space. Phylogenetic analysis mtDNA of members of the family Mytilidae indicates that this species alone has developed trioecy from dioecious ancestors.

Assessing the risk of sexual offenders on community supervision: The Dynamic Supervision Project

Assessing the risk of sexual offenders on community supervision: The Dynamic Supervision Project

Sexual offenders do great societal damage causing justifiable public concern. These factors are rapidly changing environmental and intrapersonal stresses, conditions, or events that have been shown by previous research to be related to imminent sexual reoffence. These instruments should be used to inform correctional managers as to how much risk they are managing, to inform decisions on levels of community treatment and supervision, and estimate changes in risk status pre and post treatment or other interventions. The Dynamic Supervision Project involved every Canadian province and territory and the states of Alaska and Iowa in a robust test of risk assessment methodologies. All of the probation and parole officers scoring risk of reoffence for these community-based sexual offenders were trained in sexual offender risk assessment by attending a two-day training that focussed on scoring actual case examples. The sexual recidivism rate for this widely disparate group of community-based sexual offenders was 7. This study provides evidence that trained community supervision officers can reliably score valid and useful sex offender risk assessments.
