- Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives.

- Objectives: Moderate mental health problems are highly prevalent and increasing in Swedish schoolchildren, elevating risk for future mental and somatic disability. The aim of this study was to determine whether an 8-week mindfulness-based intervention, Training for Mindfulness and Resilience (TMR), mitigates mental health symptoms and increases resilience during a 2-year follow-up. Methods: Schoolchildren (aged 9–14years) reporting moderate mental health problems were randomized into either TMR intervention group (N = 22) or control group, receiving best current practice (N = 12). We used validated questionnaires to measure anxiety, depression, anger, disruptive behavior, self-concept, resilience, stress, and mindfulness before treatment with either TMR or control, as well as at 6months, 1year, and 2years follow-up. Results: We found a statistically significant effect of TMR intervention vs control, on resilience, anxiety, anger, and disruptive behavior. Compared to baseline, TMR increased the level of resilience at 6months (p <.001); anxiety at 1 (p < =.033) and 2years (p =.04); anger at 6months (p =.004) and 2years (p =.039); disruptive behavior at 6months (p =.006). In the control group, a decrease in resilience between 6months and 2years (p =.05) was observed. No other significant effects were found in the control group. Conclusions: This study suggested that TMR improved mental health in schoolchildren with effects on anxiety and anger lasting for 2years, and on resilience and disruptive behavior lasting for 6months. Trial Registration Number: NCT04806542, date of registration 18th of March 2021, retrospectively registered.
