TRY plant trait database â enhanced coverage and open access
Plant traitsâthe morphological, anatomical, physiological, biochemical and phenological characteristics of plantsâdetermine 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 traitâbased 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 traitsâalmost complete coverage for âplant growth formâ. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and traitâenvironmental 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

Psychopathology in Multiple Sclerosis: Diagnosis, Prevalence and Treatment
Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous
system. Demyelinization of nerve fibres not only affects the motor and sensory
systems functionally, but may also cause psychopathological signs and symptoms.
In addition to the psychiatric manifestations of MS, many patients have reactive
psychological problems that are often hard to distinguish from the
âorganicâ causation of psychopathology. In any event,
psychiatric comorbidity in MS deserves greater clinical attention than has been
previously paid, because the presence of psychopathology may have deleterious
effects on the disease process and impair coping with disability
