How gene expression evolves to enable divergent ecological adaptation and how changes in gene expression relate to genomic architecture are pressing questions for understanding the mechanisms enabling adaptation and ecological speciation. Furthermore, how plasticity in gene expression can both contribute to and be affected by the process of ecological adaptation is crucial to understanding gene expression evolution, colonisation of novel niches and response to rapid environmental change. Here, we investigate the role of constitutive and plastic gene expression differences between host races, or host-specific ecotypes, of the peacock fly Tephritis conura, a thistle bud specialist.

System-involved youth are a vulnerable population at high-risk of experiencing numerous sexual reproductive health (SRH) outcomes. They are likely to have several risk factors for teen pregnancy and parenting including abuse and neglect histories, lack of a supportive consistent adult in their lives, and limited opportunities to experience normal romantic relationships. Issues of pubertal development are rarely addressed in this population.

Background: The aim of this feasibility study was to adapt and model a behavioural intervention for anxiety with autistic adults with moderate to severe intellectual disabilities.

Method: Twenty-eight autistic adults with moderate or severe intellectual disabilities, 37 carers, and 40 therapists took part in this single-group non-randomised feasibility study designed to test intervention feasibility and acceptability, outcome measures, and research processes.

Results: The intervention was judged as feasible and acceptable by autistic adults with intellectual disabilities, carers, and therapists.

Generalist plant-feeding insects are characterised by a broad host repertoire that can comprise several families or even different orders of plants. The genetic and physiological mechanisms underlying the use of such a wide host range are still not fully understood. Earlier studies indicate that the consumption of different host plants is associated with host-specific gene expression profiles.

Article Synopsis
  • Frailty is common among lung transplant candidates, and this study explores how frailty changes during the first year after the transplant.
  • Participants underwent a 12-week exercise rehabilitation program, and their frailty was assessed using the Edmonton Frail Scale (EFS) throughout the process.
  • Results showed significant improvements in physical capacity (measured by 6-Minute Walk Distance) and mental health outcomes for all participants, suggesting that pre-transplant frailty may improve with rehabilitation and should not prevent individuals from receiving a lung transplant.
