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

Man to man violence: how masculinity may work as a dynamic risk factor

This article presents masculinity as a dynamic risk factor in offences of violence between men. It argues that existing interventions into such violence, in prison, hospital and community settings may be enhanced by incorporating masculinity as a dynamic risk factor alongside other dynamic risk factors such as difficulties in anger management, social skills deficits or problems in moral reasoning. Masculinity is defined as a common denominator of men, as men, across social divisions, as opposed to existing approaches to men's identity, as men, which employ the concept of different 'masculinities' being produced by men in different social positions. The latter approach, while useful in terms of discovering men's personal identity, may be less useful in terms of explaining commonality between men, across other axes of social identity, and consequent broad patterns of violence between men. The development of masculinity as a dynamic risk factor depends on isolating masculinity from other axes of men's identity. It is argued that the individual man may demonstrate his masculinity by two categories of violence to other men: violence which includes victims in the category 'man' as worthy rivals and violence which excludes victims from the category 'man' as unworthy of being there. Masculinity as a dynamic risk factor in man to man violence is developed with particular reference to racism and homophobia
