Here is a communicating about time differences between branch and diameter growth in a tree community of ten species in Neotropical savanna ("cerrado") of Central Brazil. This work was conducted to study branch expansion and diameter growth in a period of one year between 2006 and 2007. Branch growth had begin in middle dry season and had the peak occurrence during the dry period in September, while diameter growth had begin in late dry season and peaked in the middle of wet season in December. The majority of species followed the same pattern. Branch growth did not have relation with rainfall, while diameter growth had a clear and positive relation with rainfall records. These results suggested that branch growth was not depend on rainfall but only on water status recover, while diameter growth probably depends strongly on water and to carbon assimilation that occurs after branch and leaf expansion.

The objective was to understand the relationship of the residents with the place. The research was exploratory and descriptive, with a qualitative approach. For the survey of data we are in observation, semi-structured interview and photographic records. The results revealed that Jardim Oliveira is perceived by the residents experience, that even with the limitations, they know, give meanings and meanings to the place. Topophilia was associated with feeling for the place, which could be contradictory, since the same interlocutors reported that they had experienced and / or witnessed cases of violence in the neighborhood. The Paraguai River appears as centrality in the relations of the residents with the place. The lack of basic infrastructure in the neighborhood is visible, which directly interferes with the lives of the residents, leading them to experience the socio-environmental dilemmas.Keywords: Socio-environmental Themes; Place; Paraguai River; State of Mato Grosso.RESUMENEste estudio fue realizado en el barrio Jardim Oliveira, situado en la ciudad de Cáceres / MT, a la margen izquierda del río Paraguay.

On the left bank of the Cuibá River, one of the main tributaries of the Pantanal in Mato Grosso, are located the Chacororé and Sinhá Mariana Lakes and the Mutum River, the littoral regions of which are covered with aquatic macrophytes, dominated by the species Eichhornia crassipes and Eichhornia azurea. To examine the ichthyofauna associated with this vegetation, in the year 2003, 3510 fish were collected, distributed among 83 species, and the limnological variables verified near the macrophyte stands where they were sampled. The most abundant and richest order was the Characiformes, followed by the Gymnotiformes and Siluriformes. Analysis of similarity showed a very low, or null, index that the limnological conditions and morphology of the aquatic macrophyte species provide habitat sufficiently homogeneous to give. The limnological conditions and morphology of the aquatic macrophyte species provide a sufficient habitat heterogeneity to give very low, or null, index values. Thus, environmental conservation measures should be more effective in promoting the conservation of the species, given the high levels of biological diversity found in the habitats studied.

SPACE-TEMPORAL BIOGEOCHEMISTRY OF THE LITTER IN A NATURAL FOREST ENVIRONMENT IN THE CENTRAL AMAZON. This research was aimed to evaluate the concentration of 15 chemical elements as a reference base for the quality of the litter in a forest in the central region of the Amazon. The sampling of the litter was performed monthly in two topographic positions for one year. For the quantification of the elements, digestion by nitroperchloric solution and reading by ICP OES were performed. The mean of macronutrient contents in the litter in decreasing order were Ca>K>Mg>Na. For micronutrients, the order was Al>Mn>Fe>Sr>Zn>Cu>Ba>Cr>Ni>Co>Cd for the Plateau and Al>Mn>Fe Sr>Zn>Cu>Ba>Cr>Ni>Cd>Co for the Baixio. Among the fractions, calcium had its highest concentration in the woody material, potassium in the reproductive material, while magnesium, sodium, and aluminum showed higher concentrations in the leaf fraction. Also, it was observed that the return of the elements to the soil by litter was greater in the dry period of the region, due to the greater fall in plant material. Calcium differed significantly within the same area, obtaining the highest concentrations compared to the other elements, while aluminum and zinc differed significantly between the areas studied, with a higher return for both elements on the Plateau.

Examina procedimentos do Tribunal de Contas (TC) de Mato Grosso para a contabilização da receita e despesa vinculada à Manutenção e Desenvolvimento do Ensino (MDE), pesquisa que pretende abranger todos os Tribunais de Contas do Brasil. Embora a documentação consultada não seja suficientemente detalhada, foi possível constatar equívocos e oscilação nas interpretações do TC. Por exemplo, num ano o TC considerou o percentual mínimo dos impostos (35%) fixados pela Constituição estadual, porém em outros se baseou, sem nenhuma justificativa, nos 25% da Constituição federal. Outro equívoco foi incluir na base de cálculo do percentual mínimo receitas que são adicionais a este mínimo, como os convênios e salário-educação. O surpreendente foi constatar a aceitação pelo TC, desde 2004, a partir de consulta formulada pela Secretaria Estadual de Fazenda, de que o imposto de renda dos servidores estaduais e municipais não seria classificado como imposto e, portanto, não entraria na base de cálculo dos impostos. Na classificação das despesas em MDE, o TC não teve uma interpretação uniforme sobre o pagamento dos inativos com o percentual mínimo, ora aceitando-o, ora rejeitando-o. Na questão das renúncias fiscais, que correspondem a centenas de milhões de reais por ano, o governo estadual e o TC não cumpriram a Constituição estadual, pois elas não podem ser subtraídas do montante sobre o qual incide o percentual mínimo vinculado à educação. Outro equívoco do TC foi contabilizar restos a pagar que sejam pagos no exercício. É um equívoco, porque tais despesas pertencem a exercícios anteriores, mesmo porque suas fontes também a eles pertencem. Em síntese, em conseqüência destes procedimentos equivocados dos governos estaduais e provavelmente dos municipais e sua aceitação pelo TC, é possível estimar em centenas de milhões de reais o prejuízo anual para a educação pública estadual e municipal do Estado de Mato Grosso. Palavras-chave: financiamento da educação; orçamento da educação; Tribunais de Contas; Mato Grosso. Abstract The article examines procedures adopted by the Audit Office of the Brazilian State of Mato Grosso to calculate revenue and expenditures linked to the maintenance and development of education (MDE) and is part of a research intending to cover all the Audit Offices in Brazil. Although the documentation consulted was not sufficiently detailed, it was possible to find mistakes and oscillation in the interpretations by Audit Office. For example, in one year, the Office took into account the minimum percentage of 35% of taxes set by the State Constitution, but in other years, with no justification, it considered the percentage of 25% stipulated in the Federal Constitution. A further mistake was to include in the minimum percentage revenues that are an addition to the above said minimum. It was surprising to find that the Office has accepted since 2004, after a consultation by the State Treasury Secretariat, that the income tax paid by state and municipal civil servants would not be classified as tax and would not, therefore, be included in the calculation of the percentage linked to education. In the classification of expenditures in MDE, the Office has not adopted a uniform interpretation about the payment of retired education personnel using the funds linked to education (the minimum percentage). In the issue of tax incentives reducing the funds to education and amounting to hundreds of millions of Brazilian reais per year, the State government and the Audit Office have not complied with the State Constitution, for the incentives may not be disregarded in the calculation of funds linked to education. Finally, as a result of these mistaken procedures adopted by state governments and probably by municipal administrations and their acceptance by the Audit Office, it is possible to estimate that the state and municipal education in Mato Grosso lose hundreds of millions of Brazilian reais every year. Keywords: education funding; education budget; Audit Offices; the Brazilian State of Mato Grosso.

AbstractIn this study, we aim to examine past dry and wet events for the western Anatolia, performing local and spatial reconstructions. 17 new black pine site chronologies were developed, May–June precipitation time series were reconstructed for four localities, and the first spatial May–June precipitation reconstruction was achieved for western Anatolia. The long-term local May–June precipitation reconstructions contain mostly one-year and less commonly, two-year drought events. The longest consecutive dry period (AD 1925–1928) in the reconstructed time series for Kütahya lasted four years. Spatial reconstructions revealed that between AD 1786 and 1930 the extreme dry years for all of western Anatolia were AD 1887, 1893, 1794 and 1740. The driest year during the 215-year-long period under consideration was 1887. The wettest years for the entire western Anatolia were determined to be AD 1835, 1876, 1881 and 1901. There is a big overlap between agricultural famine years and dry years as determined from reconstructions. In this context, our study provides a basis for understanding agricultural drought and better management of regional water resources.

Урожайность картофеля в России остается низкой из-за возделывания не только в производственных предприятиях, но и в личных подсобных хозяйствах (ЛПХ), где возделывание трудоемкое, неиндустриального типа. Однако картофель, выращиваемый в ЛПХ, может быть интегрирован в сегмент производства экологически чистого картофеля при поддержке Министерства сельского хозяйства РФ и переведен из сектора личного потребления в формат коммерческой деятельности. Особенность органического земледелия отказ в технологиях возделывания от использования любых химических соединений. Поэтому использование природного материала концентрата глауконитового песка Бондарского месторождения Тамбовской области становится все более актуально. Цель нашей работы изучить влияние концентрата глауконитовых песков на продуктивность картофеля. Исследования проводили в 20182019 годах на участке лаборатории овощеводства РГАУМСХА имени К.А. Тимирязева. Почвы дерново-подзолистые среднесуглинистые, мощность пахотного слоя 2022 см, легкогидролизуемого азота 9,3 мг на 100 г почвы, фосфора 15,0, калия 8,3 мг на 100 г почвы, содержание гумуса 2,6, рН сол. 5,8. Использовали сорт Удача с различными концентрациями глауконитовых песков (10 г/раст., 20 г/раст., 30 г/раст., 40 г/раст.). Повторность опытов трехкратная. Варианты в опыте были размещены рендомизированным методом. Площадь одной опытной делянки 25 м2. Схема посадки 7035 см. Густота стояния 46,7 тыс. растений на га. На посадку использовали семeна средней фракции (4080 г), элиту. Все варианты высажены одновременно в один год. Были проведены наблюдения и учеты фенологические, биометрические, структуры урожая. Технология возделывания стандартная. Установлено, что внесение природного минерала глауконитовых песков при возделывании картофеля раннего дает прибавку урожая до 30,2, лучшая норма 30 г/раст.The yield of potatoes in Russia remains low due to cultivation not only in production enterprises, but also in private farms, where cultivation is labor-intensive, non-industrial type. However, potatoes grown in PSP can be integrated into the segment of production of organic potatoes with the support of the Ministry of agriculture of the Russian Federation and transferred from the sector of personal consumption to the format of commercial activity. The peculiarity of organic farming is the refusal of cultivation technologies to use any chemical compounds. Therefore, the use of natural material-a concentrate of glauconite sand from the Bondar Deposit in the Tambov region is becoming more and more relevant. The purpose of our work is to study the effect of glauconite sand concentrate on potato productivity. The research was carried out in 20182019 on the site of the vegetable growing laboratory of the Russian State Agrarian University Moscow Timiryazev Agricultural Academy. Sod-podzolic soils are medium-loamy, the capacity of the arable layer is 2022 cm, easily hydrolyzed nitrogen is 9.3 mg per 100 g of soil, phosphorus is 15.0, potassium is 8.3 mg per 100 g of soil, humus content is 2.6, pH 5.8. We used the Udacha variety with different concentrations of glauconite sands (10 g/plant, 20 g/plant, 30 g/plant, 40 g/plant). The repeatability of experiments is three-fold. The variants in the experiment were placed by rendomized method. The area of one experimental plot is 25 m2. The planting scheme is 7035 cm. The density of standing 46.7 thousand plants per ha. Seeds of the average fraction (4080 g), elite, were used for planting. All variants are planted simultaneously in one year. Observations and records of phenological, biometric, and crop structure were made. Cultivation technology is standard. Adding the natural mineral glauconite sands when cultivating early potatoes gives an increase in yield up to 30.2, the best rate is 30 g/plant.

ABSTRACT The distribution of the callitrichids inhabiting the Tapajós-Xingu interfluvium is still poorly understood, probably because of the limited number of studies in this remote region. Mico emiliae is a callitrichid endemic to Brazil, occurring between the Jamanxim and Teles Pires rivers, and Serra do Cachimbo in the west and Iriri River in the east, in the states of Pará and Mato Grosso. However, its current distribution is still uncertain. After ca. 430-km surveys in Serra do Pardo National Park, we successfully confirmed the occurrence of this species for the first time approximately 180 km east of its previously known eastern limit in Pará. Our records expand the distribution of M. emiliae to the left bank of the Xingu River, increasing the known extent of its occurrence by 83%.
