TRY plant trait database – enhanced coverage and open access

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

A High-Morbidity Outbreak of Methicillin-Resistant Staphylococcus aureus among Players on a College Football Team, Facilitated by Cosmetic Body Shaving and Turf Burns

Background. Athletics-associated methicillin-resistant Staphylococcus aureus (MRSA) infections have become a high-profile national problem with substantial morbidity. Methods. To investigate an MRSA outbreak involving a college football team, we conducted a retrospective cohort study of all 100 players. A case was defined as MRSA cellulitis or skin abscess diagnosed during the period of 6 August (the start of football camp) through 1 October 2003. Results. We identified 10 case patients (2 of whom were hospitalized). The 6 available wound isolates had indistinguishable pulsed-field gel electrophoresis patterns (MRSA strain USA300) and carried the Panton-Valentine leukocidin toxin gene, as determined by polymerase chain reaction. On univariate analysis, infection was associated (P\u3c .05) with player position (relative risk [RR], 17.5 and 11.7 for cornerbacks and wide receivers, respectively), abrasions from artificial grass (i.e., turf burns ; RR, 7.2), and body shaving (RR, 6.1). Cornerbacks and wide receivers were a subpopulation with frequent direct person-to-person contact with each other during scrimmage play and drills. Three of 4 players with infection at a covered site (hip or thigh) had shaved the affected area, and these infections were also associated with sharing the whirlpool ⩾2 times per week (RR, 12.2; 95% confidence interval, 1.4-109.2). Whirlpool water was disinfected with dilute povidone-iodine only and remained unchanged between uses. Conclusions. MRSA was likely spread predominantly during practice play, with skin breaks facilitating infection. Measures to minimize skin breaks among athletes should be considered, including prevention of turf burns and education regarding the risks of cosmetic body shaving. MRSA-contaminated pool water may have contributed to infections at covered sites, but small numbers limit the strength of this conclusion. Nevertheless, appropriate whirlpool disinfection methods should be promoted among athletic trainers
