Wind Shapes the Growth Strategies of Trees in a Tropical Forest.

In tropical forests, trees strategically balance growth patterns to optimise fitness amid multiple environmental stressors. Wind poses the primary risk to a tree's mechanical stability, prompting developments such as thicker trunks to withstand the bending forces. Therefore, a trade-off in resource allocation exists between diameter growth and vertical growth to compete for light. We explore this trade-off by measuring the relative wind mortality risk for 95 trees in a tropical forest in Panama and testing how it varies with tree size, species and wind exposure. Surprisingly, local wind exposure and tree size had minimal impact on wind mortality risk; instead, species wood density emerged as the crucial factor. Low wood density species exhibited a significantly greater wind mortality risk, suggesting a prioritisation of competition for light over biomechanical stability. Our study highlights the pivotal role of wind safety in shaping the life-history strategy of trees and structuring diverse tropical forests.

Evaluating step-down, intermediate care programme in Buckinghamshire, UK: a mixed methods study.

BACKGROUND: Intermediate care (IC) services are models of care that aim to bridge the gap between hospital and home, enabling continuity of care and the transition to the community. The purpose of this study was to explore patient experience with a step-down, intermediate care unit in Buckinghamshire, UK. METHODS: A mixed-methods study design was used. Twenty-eight responses to a patient feedback questionnaire were analysed and seven qualitative semi-structured interviews were conducted. The eligible participants were patients who had been admitted to the step-down IC unit. Interview transcripts were analysed using thematic analysis. FINDINGS: Our interview data generated five core themes: (1) "Being uninformed", (2) "Caring relationships with health practitioners", (3) "Experiencing good intermediate care", (4) "Rehabilitation" and (5) "Discussing the care plan". When comparing the quantitative to the qualitative data, these themes are consistent. CONCLUSIONS: Overall, the patients reported that the admission to the step-down care facility was positive. Patients highlighted the supportive relationship they formed with healthcare professionals in the IC and that the rehabilitation that was offered in the IC service was important in increasing mobility and regaining their independence. In addition, patients reported that they were largely unaware about their transfer to the IC unit before this occurred and they were also unaware of their discharge package of care. These findings will inform the evolving patient-centred journey for service development within intermediate care.
