Abstract: There are few animal germplasm/gene bank collections in Brazil, and basic studies are needed to attend the future internal and external demands from international partners. The aim of this work was to validate a ?proof of concept? that integrates spatial (georeferenced data) and genetic data regarding the local of origin from 3518 DNA samples from 17 different genetic groups or breeds of sheep in the Brazilian Germplasm bank. Spatialisation shows that not all genetic groups have samples in the bank, and collection is concentrated in the conservation nuclei spread nationwide. Only 21% of states with a specific breed have samples in the gene bank. The mean number of animals sampled per collection was 32, while the mean distance travelled to collect samples was 262 km from the conservation nuclei. For example, the Brazilian Somali were only collected in the conservation nucleus in Ceará State. No samples were collected to date for the Cariri breed, which is recognised by the Brazilian Ministry of Agriculture. Only two farms and one breed in the bank are from the northern region. Of the 27 states, there are samples in the gene bank of sheep from 13, so several states have no samples, requiring collection from herds outside the official system of conservation to make sure that studies using this germplasm realised are not biased. Significant genetic differences are seen above 332 km, which should guide future sampling efforts. Suggestions are given for improving the quantity, quality and diversity of samples in the gene bank.

EN-US: Atrazine still is a widely used herbicide in tropical soils to control annual broad-leaved weeds and annual grasses mainly in maize and sorghum plantations. Sorption and desorption in such soils are important processes that affect transport, ending with soil and water contamination, not only in these soils, but in other soils around the world. Lime and phosphate are important amendments in tropical soils to mitigate low fertility. These treatments can affect interaction among soil particles and between soil and atrazine. The objectives here were to evaluate the effect of lime, phosphate, and lime + phosphate treatments on sorption and transport of atrazine in a Typic Hapludult, using soil-erosion-plots at field conditions in a 3%-slope landscape 20 m away from the floodplain. Water- and sediment-sampler devices were used to measure runoff during an entire rainy season. Soil, water and sediments were sampled and analyzed for atrazine. By increasing pH and changing soil organic matter interaction with mineral particles, lime and lime + phosphate decreased sorption in the upper 20-cm layer. This affected leaching and runoff of atrazine, showing that when lime and lime + phosphate were applied to soil, this herbicide had more potential to go deeper in the soil profile, towards the groundwater, or to runoff towards the lower part of the landscape. However, even with increasing leaching, the amount of rainfall, and water infiltration, were enough to dilute atrazine into levels below the maximum contaminant level (MCL) of atrazine in drinking water. | PT-BR: A atrazina é um herbicida ainda amplamente utilizado em solos tropicais para controlar plantas daninhas de folhas largas anuais e gramíneas anuais principalmente nas culturas de milho e sorgo. A sorção e dessorção nesses solos são processos importantes que afetam o transporte, terminando com a contaminação do lençol freático e de mananciais de água superficial. A calagem e a fosfatagem são importantes práticas em solos tropicais para mitigar problemas de fertilidade. Esses tratamentos podem afetar a interação das partículas do solo com a atrazina. Neste trabalho foi avaliado o efeito de tratamentos calagem, da fosfatagem e da calagem + fosfatagem na sorção e transporte de atrazina em um Argissolo Vermelho Amarelo distrófico, em condições de campo, em parcelas de perdas de solo por erosão, numa paisagem de 3% de declive montadas a distância de 20 m da várzea. Dispositivos de amostragem de água e sedimentos foram usados para medir a erosão durante uma estação chuvosa de 2007-2008, comum para a região (outubro a abril). Solo, água e sedimentos foram amostrados para determinação de resíduos de atrazina. Os tratamentos com calagem e com calagem mais fosfatagem diminuíram a sorção da atrazina na camada superficial, por elevar o pH e afetar a interação entre a matéria orgânica do solo e suas partículas minerais, aumentando a lixiviação para as camadas inferiores do perfil do solo. Esse comportamento mostrou que a calagem e, principalmente, a calagem mais fosfatagem, facilitam a lixiviação do herbicida, evidenciando o potencial para contaminar a água do lençol freático. No entanto, a quantidade de chuva foi suficiente para aumentar a quantidade de água no lençol freático e diluir a quantidade de atrazina para níveis abaixo do limite aceitável para água potável.
