- 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.

- Gartland type III fracture is the most troublesome type of supracondylar humerus fracture. These injuries most often occur in school age children, but they are seen in pediatric patients of all ages. The goal of this study was to analyze toddlers with Gartland type III fractures to identify clinically significant differences compared with older children. A retrospective cohort study was conducted with 94 toddlers (<3 years) and 378 older children (3 to 12 years). Factors including demographics, mechanism of injury, additional injuries, location of trauma, pin configuration, postoperative complications, follow-up time, and compliance with the treatment plan were collected and compared. The study included 94 toddlers (59% girls, 2.11±0.64 years) and 378 older children (48% girls, 6.32±1.89 years), chosen at random, who were treated between 2000 and 2015. Among toddlers, fractures were more likely to occur at home (P<.001) and to be the result of suspected nonaccidental trauma (P<.001). Older children had more additional injuries (P<.001), but were no more likely to have an open fracture (P=.59) or a flexion-type fracture (P=.42). Older children were more likely to undergo open reduction (P=.03), whereas toddlers were more likely to be treated with a medial pin (P<.001). Toddlers experienced more cubitus varus (P<.001) and loss of reduction (P=.02). No difference was found in length of follow-up (P=.83) or compliance with the treatment plan (P=.11). This study provides novel insights into clinical differences between toddlers and older children with Gartland type III fractures. Knowledge of these differences can facilitate the delivery of targeted, age-specific care for patients with type III supracondylar humerus fractures. [Orthopedics. 2020;43(5);e421-e424.].
