Effects of individual variation in length, condition and run-time on return rates of wild-reared Atlantic salmon Salmo salar smolts.

Groups of wild-reared Atlantic salmon Salmo salar smolts were captured during their seaward migration on a tributary of the River Conon, Scotland, U.K., from 1999 to 2014 and tagged with passive integrated transponders (PIT). Fish that subsequently returned to the river after growing at sea were recorded automatically by a PIT-detector in a fish pass. Return rate was related directly to length and condition and inversely to day of the year that the smolt was tagged. Over years, as the study progressed, there was a significant increase in the proportion of smolts returning after two or more years at sea and no trend in returns of salmon having spent one winter at sea. There was no trend in the date of return of salmon across the study period. Fish that had spent more winters at sea returned earlier in the year.

Eye movement desensitization and reprocessing in posttraumatic stress disorder: a pilot study using assessment measures.

Spectacular claims have been made regarding the efficacy of eye movement desensitization and reprocessing (EMDR) in the treatment of posttraumatic stress disorder (PTSD), but almost entirely on the basis of patients' reports and without objective criteria. This study reports on the treatment of eight patients with a diagnosis of PTSD who received EMDR treatment over four sessions. Assessment measures included two structured interviews, three self-report inventories, and the electromyogram (EMG). Assessments were conducted pre and posttreatment, and at 3-month follow-up. Despite some residual pathology at posttreatment and follow-up, significant improvements were obtained on all measures and across all PTSD symptom clusters. Compared with other treatments of PTSD, change was achieved in far fewer sessions.
