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.Rest of authors: Decky Junaedi, Robert R.

Potencial de uso e qualidade estrutural de dois solos cultivados com cana-de-açúcar em Goianésia (GO) Use potential and structural quality of two soils under sugarcane production in Goianésia, Goiás State, Brazil

Com a expansão do setor sucroalcooleiro, tanto os solos com poucas limitações como aqueles que apresentam riscos permanentes ao cultivo intensivo tiveram sua vegetação nativa removida e foram incorporados ao processo produtivo. Para isso, a adoção de sistemas de manejo que mantêm a estrutura do solo pode ser a chave para a manutenção da qualidade e sustentabilidade dos agrossistemas canavieiros. Assim, o objetivo deste estudo foi avaliar o potencial de uso para cana-de-açúcar e a qualidade estrutural de um Cambissolo Háplico Tb distrófico (CXvbd) e um Latossolo Vermelho-Amarelo distrófico (LVAd), no município de Goianésia, GO. Em cada área, realizou-se a classificação das terras quanto à capacidade de uso. Foram coletadas amostras deformadas nas profundidades correspondentes aos horizontes diagnósticos superficiais e subsuperficiais, para caracterização química e físico-hídrica dos solos. Nas profundidades de 0 a 0,05, 0,1 a 0,15 e 0,3 a 0,4 m, foram coletadas amostras indeformadas para determinação da porosidade do solo, da curva de retenção de água, do intervalo hídrico ótimo e da pressão de preconsolidação. O enquadramento dos solos no sistema de capacidade de uso da terra apontou o CXvbd como pertencente à classe IVe, e o LVAd, à classe IIIs. Os resultados das análises dos atributos químicos e físico-hídricos do CXvbd indicaram que o cultivo contínuo com cana-de-açúcar, mesmo com o enquadramento na classe IVe do sistema de capacidade de uso, deve-se à adoção de terraceamento agrícola, além do fato de essa cultura promover pequeno revolvimento do solo e aumentar a cobertura do solo quando colhida crua. O CXvbd apresentou maior disponibilidade de água para as plantas, o que tende a trazer benefícios à cultura. O LVAd, nas condições de estudo, é mais suscetível à compactação, necessitando da adequação do tráfego de máquinas.<br>With the expansion of the sugar/alcohol sector, the native vegetation was removed from soils with few limitations as well as with great risks for intensive cultivation and the areas incorporated in the production process. Therefore, the adoption of management systems that maintain the soil structure may be a key for the maintenance of the quality and sustainability of sugarcane production systems. The objective of this study was therefore to evaluate the use potential for sugarcane and structural quality of a Dystrophic Haplic Cambisol (CXvbd) (Inceptisol) and Dystrophic Red-Yellow Latosol (LVAd) (Oxisol), in the county of Goianésia, Goiás State. The soils of each area were classified for their use capacity. Disturbed soil samples were collected at depths corresponding to the surface and subsurface diagnostic horizons, for chemical and physical-hydric characterization. Undisturbed samples were collected (from the layers 0-0.05, 0.1-0.15 and 0.3-0.4 m) to determine soil porosity, water retention curves, the least limiting water range and preconsolidation pressure. The evaluation of soils by the land use capacity system indicated that CXvbd belongs to class IVe and LVAd to IIIs. Results of the analysis of the chemical and physical-hydric attributes of the CXvbd indicated that a continuous sugar-cane cultivation, despite the classification as IVe in the use potential system, was due to the adoption of agricultural terraces, aside from the fact that the degrees of soil revolving was lower and of soil cover higher, when sugarcane was harvested green The water availability for plants was highest for CXvbd, which tends to be advantageous for crops. In the study conditions, the LVAd was most susceptible to compaction, which requires limitations of machinery traffic

Spatial variability of physical attributes of an alfisol under different hillslope curvatures Variabilidade espacial de atributos físicos de um argissolo sob diferentes curvaturas do relevo

The influence of relief forms has been studied by several authors and explains the variability in the soil attributes of a landscape. Soil physical attributes depend on relief forms, and their assessment is important in mechanized agricultural systems, such as of sugarcane. This study aimed to characterize the spatial variability in the physical soil attributes and their relationship to the hillslope curvatures in an Alfisol developed from sandstone and growing sugarcane. Grids of 100 x 100 m were delimited in a convex and a concave area. The grids had a regular spacing of 10 x 10 m, and the crossing points of this spacing determined a total of 121 georeferenced sampling points. Samples were collected to determine the physical attributes related to soil aggregates, porosity, bulk density, resistance to penetration and moisture within the 0-0.2 and 0.2-0.4 m depth. Statistical analyses, geostatistics and Student's t-tests were performed with the means of the areas. All attributes, except aggregates > 2 mm in the 0-0.2 m depth and macroporosity at both depths, showed significant differences between the hillslope curvatures. The convex area showed the highest values of the mean weighted diameter, mean geometric diameter, aggregates > 2 mm, 1-2 mm aggregates, total porosity and moisture and lower values of bulk density and resistance to penetration in both depth compared to the concave area. The number of soil attributes with greater spatial variability was higher in the concave area.<br>A influência das formas do relevo tem sido estudada por diversos autores e explica a variabilidade dos atributos do solo na paisagem. Os atributos físicos do solo são dependentes das formas do relevo, e a avaliação desses atributos é importante em sistemas mecanizados como o da cultura de cana-de-açúcar. O presente estudo teve como objetivo caracterizar a variabilidade espacial dos atributos físicos de Argissolos desenvolvidos de arenito e cultivados com cana-de-açúcar bem como a relação desses com as curvaturas do relevo. Uma malha de dimensão de 100 x 100 m foi delimitada em uma área caracterizada pela forma convexa e outra em uma área caracterizada pela forma côncava. As malhas tinham espaçamento regular de 10 x 10 m, e os pontos de cruzamento desse espaçamento determinaram os pontos de coleta das amostras, num total de 121 pontos amostrais georreferenciados. Amostras foram coletadas para determinação dos atributos físicos: agregados, porosidade, densidade do solo, resistência à penetração e umidade nas profundidades 0,00-0,20 e 0,20-0,40 m. Foram realizadas análises estatísticas e geoestatísticas. Todos os atributos, com exceção dos agregados > 2 mm na profundidade de 0,00-0,20 m e dos macroporos nas duas profundidades, apresentaram diferença significativa entre as curvaturas. A área convexa apresentou os maiores valores de diâmetro médio ponderado, diâmetro médio geométrico, agregados > 2 mm, agregados de 2-1 mm, volume total de poros e umidade e os menores valores de densidade do solo e resistência à penetração nas duas profundidades estudadas, em relação à área côncava. A área côncava apresentou maior número de atributos do solo com maior variabilidade espacial
