    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

    The objective of this study was to estimate the variance components for body weight in Japanese quails by Bayesian procedures. The body weight at hatch (BWH) and at 7 (BW07), 14 (BW14), 21 (BW21) and 28 days of age (BW28) of 3,520 quails was recorded from August 2001 to June 2002. A multiple-trait animal model with additive genetic, maternal environment and residual effects was implemented by Gibbs sampling methodology. A single Gibbs sampling with 80,000 rounds was generated by the program MTGSAM (Multiple Trait Gibbs Sampling in Animal Model). Normal and inverted Wishart distributions were used as prior distributions for the random effects and the variance components, respectively. Variance components were estimated based on the 500 samples that were left after elimination of 30,000 rounds in the burn-in period and 100 rounds of each thinning interval. The posterior means of additive genetic variance components were 0.15; 4.18; 14.62; 27.18 and 32.68; the posterior means of maternal environment variance components were 0.23; 1.29; 2.76; 4.12 and 5.16; and the posterior means of residual variance components were 0.084; 6.43; 22.66; 31.21 and 30.85, at hatch, 7, 14, 21 and 28 days old, respectively. The posterior means of heritability were 0.33; 0.35; 0.36; 0.43 and 0.47 at hatch, 7, 14, 21 and 28 days old, respectively. These results indicate that heritability increased with age. On the other hand, after hatch there was a marked reduction in the maternal environment variance proportion of the phenotypic variance, whose estimates were 0.50; 0.11; 0.07; 0.07 and 0.08 for BWH, BW07, BW14, BW21 and BW28, respectively. The genetic correlation between weights at different ages was high, except for those estimates between BWH and weight at other ages. Changes in body weight of quails can be efficiently achieved by selection

    OBJETIVO: Descrever a relação entre a frequência de insatisfação com a imagem corporal e a presença de sintomas de transtornos alimentares em adolescentes. MÉTODOS: O estudo foi realizado com uma amostra de 300 adolescentes, de ambos os sexos, na faixa etária de 10 a 17 anos, estudantes de uma escola pública estadual da cidade do Recife, Brasil. Foram utilizadas as versões brasileiras para adolescentes de três escalas autoaplicativas (EAT-26, BITE e BSQ), além de um questionário contendo dados biodemográficos. RESULTADOS: A frequência de sintomas de transtornos alimentares detectada pelo EAT-26 foi de 32,3%; 2,3% para comportamentos sugestivos de bulimia nervosa, por meio da escala BITE, tendo 36,67% dos alunos apresentado padrão alimentar não usual; 5,6% apresentaram insatisfação com a imagem corporal; 8,6% demonstraram tendência à preocupação com a insatisfação com a imagem corporal e 17,6% apresentaram leve insatisfação, além de 66,3%, que mostraram normalidade em relação à sua forma corporal. CONCLUSÃO: Os adolescentes apresentaram níveis de alteração na autoimagem corporal, com alta frequência de insatisfação da imagem corporal, podendo apresentar associação com comportamentos alimentares inadequados

    Práticas baseadas em evidências publicadas no Brasil: identificação e análise de suas vertentes e abordagens metodológicas

    Revisão integrativa de estudos brasileiros sobre práticas baseadas em evidências (PBE) em saúde, publicados em periódicos ISI/JCR, nos últimos 10 anos. O objetivo foi identificar as especialidades que mais realizaram estes estudos, seus enfoques e abordagens metodológicas. A partir de critérios de inclusão, foram selecionados 144 trabalhos. Os resultados indicam que a maior quantidade de estudos feitos em PBE foram sobre infância e adolescência, infectologia, psiquiatria/saúde mental e cirurgia. Os enfoques predominantes foram prevenção, tratamento/reabilitação, diagnóstico e avaliação. As metodologias mais empregadas foram revisão sistemática sem ou com metanálise, revisão de protocolos ou síntese de estudos de evidências já disponíveis, e revisão integrativa. Constata-se forte expansão multiprofissional da PBE no Brasil, contribuindo para a busca de práticas mais criteriosas pela reunião, reconhecimento e análise crítica dos conhecimentos produzidos. O estudo contribui também para a própria análise dos modos de fazer pesquisa e novas possibilidades de investigação
