Abstract: Temperate forests are currently facing multiple stresses due to climate change, biological invasions, habitat fragmentation and fire regime change. How these stressors interact with each other influences how, when and whether ecosystems recover, or whether they adapt or transition to a different ecological state. Because forest recovery or collapse may take longer than a human lifetime, predicting the outcomes of different stressor combinations remains difficult. A clearer vision of future forest trajectories in a changing world may be gained by examining collapses of forests in the past. Here, we use long‐term ecological data to conduct a post‐mortem examination of the decline of maritime pine forests ( Pinus pinaster Ait.) on the SW Iberian Peninsula 7000–6500 years ago. Portugal and Spain. We compared four palaeoecological records—two with pine declines and two without—using a multiproxy approach. Bioclimatic differences between the four sites were explored. Proxies for past vegetation and disturbance (fire and grazing) were compared with independent palaeoclimatic records. We performed functional traits analysis and used phase plots to examine the causes of pine decline. The pine decline represents a critical transition in SW Iberia, which lies close to maritime pine's bioclimatic limits. Prolonged drought likely killed trees and suppressed the fires that normally stimulate pine germination and pinewood recovery. Increased grazing pressure facilitated the rapid spread of resprouter shrubs. These competed with pine trees and ultimately replaced them. Our data highlight complex interactions between climate, fire, grazing and forest resilience. The pine decline occurred at least a century after post‐fire resprouters overtook obligate seeders in the vegetation, constituting an early‐warning signal of forest loss. Fire suppression, resprouter encroachment and grazing may threaten the persistence of Mediterranean forests as droughts become more frequent and extreme.

Abstract: To meet the growing needs of a erse population, it is critical that healthcare service provision is underpinned by innovative, cost-effective, and sustainable services and solutions. The role of the nurse practitioner creates an opportunity to meet the increasing demands of complex care and enables greater access to high quality care. Understanding how best to support nurse practitioner candidates to develop into the nurse practitioner role will create greater opportunities to transform service delivery and improve healthcare outcomes. To identify key factors that support and positively impact the implementation of nurse practitioner candidacy programs and candidate experiences. A scoping review of research and grey literature was conducted using Joanna Briggs Institute methodology. For the research literature, eight electronic databases (Embase, Medline, CINAHL, Web of Science, Cochrane Library, Joanna Briggs Institute, PubMed and PsycINFO) were searched followed by a hand search of the reference lists of published systematic reviews and relevant topical papers. A review of national and international grey literature sources was completed. Identification of a service gap, developing and promoting a clear role for the nurse practitioner candidate, integration into a multi-disciplinary team with strong mentorship receptorship support, continuing professional development, and evaluation of the program were identified as key factors in the research and grey literature. A well-designed candidacy program can facilitate transition of the candidate into an autonomous, fully independent nurse practitioner. Recommendations to support the implementation of these roles into the clinical setting have been generated.

Abstract: Nowadays, the need for protective devices at man–machine interfaces is increasing in the fields of traffic, sports, construction, and military, etc. Dynamic pressure sensing technology with wide measuring range, high sensitivity, softness, and fast response is crucial for evaluation and optimization of the personal protective equipment under impact scenarios. However, current sensors hardly possess all the aforesaid required characteristics. For the first time, this article reports the evaluation and application of an innovative soft pressure sensor with modulus of 2 MPa, maximum pressure of 8 MPa, and over 500‐Hz frequency. A theoretical model, taking strain rate into consideration, is established to characterize the dynamic sensing behavior. A sensing network in the form of smart clothing is developed and used in a sled crash test, which is a standard approach to evaluate the safety of automobiles in collisions. The pressure distribution over the dummy's surface during the crash is acquired in real‐time, and compared with numerical simulations. This study is important to the study of occupant injury and crashworthiness design for vehicles, and it will benefit the automotive industry. With the built‐in sensing network, the smart clothing has promising applications in the pressure mapping of 3D flexible man–machine interface under impact scenarios.
