Climate change has dramatic impacts on ecological systems, affecting a range of ecological factors including phenology, species abundance, diversity, and distribution. The breadth of climate change impacts on ecological systems leads to the occurrence of fingerprints of climate change. However, climate fingerprints are usually identified across broad geographical scales and are potentially influenced by publication biases.

Little is known about the mechanisms through which routine outcome monitoring (ROM) influences psychotherapy outcomes. In this secondary analysis of data from a randomized clinical trial (Brattland et al., 2018), we investigated whether the working alliance mediated the effect of the Partners for Change Outcome Monitoring System (PCOMS), a ROM system that provides session-by-session feedback on clients' well-being and the alliance.

Background: Patients dropping out of mental health treatment is considered a widespread and significant obstacle to providing effective treatment, thus reducing the probability of patients achieving the desired improvement. Here, relative to ordinary treatment, we investigate the effects of providing an educational group programme before mental health treatment on mental health symptomatology and the risk of patients dropping out or prematurely discontinuing treatment.

Methods: A randomized controlled trial in which adults referred to a community mental health center were randomized to either a Control Group (n = 46) or a pretreatment educational programme followed by treatment as usual (Intervention Group, n = 45).

This study investigated the effects of the Partners for Change Outcome Management System (PCOMS) in adult outpatient treatment at a hospital-based mental health clinic. It also investigated whether the effects differed with the timing of the treatment within a 4-year implementation period, with clients' initial distress levels, and between therapists. Adult clients (N = 170) were randomized to treatment as usual (TAU) or routine outcome monitoring (ROM).

The aim of this study was to test the hypothesis that hatchery brown trout Salmo trutta smolts, with 50% reduced or no feeding over the last 5 months before release, were more likely to migrate to the sea than individuals with standard feeding ratios. The juvenile fish were divided into three groups 176 days before release: (A) with no feeding, (B) with 50% and (C) with 100% feeding. To study their seaward migration, 40 fish from each feeding group were tagged with acoustic transmitters and tracked by automatic listening stations in the River Nidelva, Trondheim, Norway, its estuary and in the nearest marine environment.
