Global dataset of soil organic carbon in tidal marshes.

Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil organic carbon (SOC) stocks provide an important resource for researchers, natural resource managers, and policy-makers working towards the protection, restoration, and valuation of these ecosystems. We collated a global dataset of tidal marsh soil organic carbon (MarSOC) from 99 studies that includes location, soil depth, site name, dry bulk density, SOC, and/or soil organic matter (SOM). The MarSOC dataset includes 17,454 data points from 2,329 unique locations, and 29 countries. We generated a general transfer function for the conversion of SOM to SOC. Using this data we estimated a median (± median absolute deviation) value of 79.2 ± 38.1 Mg SOC ha-1 in the top 30 cm and 231 ± 134 Mg SOC ha-1 in the top 1 m of tidal marsh soils globally. This data can serve as a basis for future work, and may contribute to incorporation of tidal marsh ecosystems into climate change mitigation and adaptation strategies and policies

Do environmental influences alter motor abilities acquisition? A comparison among children from day-care centers and private schools Influências do ambiente podem alterar a aquisição de habilidades motoras? Uma comparação entre pré-escolares de creches públicas e escolas privadas

Development occurs in a proper rhythm as result of genetic inheritance and environment factors. This study had the aim to identify some environmental risk factors for the motor development in two groups of healthy children. 100 pre-school aged (five years children) from two day-care centers and a private school were evaluated, in Recife-PE. All the children underwent to a motor skills assessment and their parents answered a questionnaire. The children from the public nursery remained behind in fine motor skills. The results showed that the biologically healthy children development can suffer negative influence of the environmental risk factors. In this research these factors were: the father absence, improper toys use to the correct age, the place were the child was kept in the early childhood, the lack of pedagogical guidance and extra-parental socialization and low familiar socioeconomic status.<br>O desenvolvimento ocorre num ritmo resultante da interação entre herança genética e fatores ambientais. Este estudo teve por objetivo identificar alguns fatores de risco ambientais para o desenvolvimento motor, em dois grupos de crianças saudáveis. Foram avaliadas 100 crianças (idade:5 anos) provenientes de duas creches públicas e uma escola particular, em Recife-PE. Todas as crianças foram submetidas a uma avaliação das habilidades motoras e seus pais responderam a um questionário. As crianças da creche pública mostraram atraso no campo das habilidades motoras finas. Os resultados indicaram que o desenvolvimento das crianças biologicamente saudáveis pode sofrer influência negativa dos fatores de risco ambientais. Os fatores encontrados foram: a ausência do pai; a utilização de brinquedos inadequados para faixa etária; o local onde a criança era mantida em idades precoces da infância; a falta de orientação pedagógica e de socialização extra-familiar precoce, e a baixa condição socioeconômica familiar
