Bioma cerrado: um estudo de valoração e conservação da biodiversidade e dos recursos naturais

The region of the biome Cerrado is under threat due to the replacement of their native areas for expansion of agriculture and livestock. This occupation is responsible for the loss of about 50% of two million square kilometers of original native savannah. The land use, without control or zoning, has caused serious damage to natural resources of this biome, considered as an international hotspot area. As a result, some problems caused by ecological imbalances already topping the urban and rural environments, such as species extinction, water scarcity and desertification. Any occupation in this biome should be evaluated with caution, because this region, besides being considered one of the most productive of Brazil, is also rich in biodiversity and water resources. The understanding of the importance of the Cerrado biome and its remaining areas, allows the preparation of detailed studies of environmental valuation, which is essential for the development of conservation policies, avoiding even greater environmental impacts. To meet the growing demand for food, you can increase productivity through agroforestry, for example, and to preserve the remaining areas, you can create new protected areas and tailor existing units

Caracterização do grau de impermeabilização relativa das vertentes de uma bacia hidrográfica urbanizada: o exemplo do Córrego da Servidão - Rio Claro (SP)

The expansion and growth of towns affect the hydrology of watersheds included in the urban environment, impacting mainly the slopes and river channels. This interference can be in soil waterproofing, the runoff of rainwater, the extinction of surface drainage, the dynamics of flooding processes, etc. For studies concerning the hydrological behavior of watersheds, Remote Sensing techniques have been used to support the acquisition and analysis of data and also to generate new information from the integration of these data. In this context, the study aimed to characterize scenarios and conduct comparative analysis of urban occupation of parts of watershed the Córrego da Servidão, in Rio Claro (SP) and analyze the degree of waterproofing on the ground. With the support of the soil categories of waterproofing listed in Soil Conservation Service (S.C.S / USDA) this analysis was conducted, considering the scenarios of 1958 and 2006, through processes of interpretative analysis of panchromatic and color images aerofotogramétricas. The analysis, data integration and mapping of the watershed area were conducted in an environment of a Geographic Information System (GIS). Maps were obtained to characterize land cover in the watershed, showing the evolution of urban occupation, as well as indicating the densely built and waterproofed

Estimativa da diversidade genética de Queixadas (Tayassu pecari) da região do Taboco (Corguinho, MS)

The Brazilian fauna has been constantly threatened by deforestation and forest fragmentation. As a result, many populations become isolated and small which negatively impacts their genetic diversity, putting them at a higher risk of extinction than large and stable populations. The aim of this work was to estimate the genetic diversity of white-lipped peccaries (Tayassu pecari) in the region of Taboco (Corguinho, MS), a fragmented area; and to compare these estimates with that obtained previously for two populations from Brazilian Pantanal, which is considered a relatively well-preserved biome and where the species is not threatened. A total of 18 blood and 72 hair samples of white-lipped peccaries had their DNA extracted and amplified for five polymorphic microsatellite loci. With the individuals identified, genetic diversity indicators (such as number of alleles, allelic richness, expected end and observed) and the inbreeding coefficient FIS were calculated. In addition, to verify if the population suffered a recent population bottleneck, we used the tests implemented in the program Bottleneck. The population of Taboco showed no evidence of recent population bottleneck (p > 0.05) or inbreeding (FIS = 0.008; p > 0.022). In addition, the levels of genetic diversity in this population (mean number of alleles = 2.60; mean allelic richness = 2.56 mean observed and expected heterozygosities = 0.45 and 0.47, respectively) were statistically similar to those found previously for the two populations from Pantanal (p > 0,05); although the region of Taboco is more impacted than the Pantanal. Even though we showed no evidence of loss of genetic diversity, it does not mean that the population is not suffering with fragmentation; but that there was not sufficient time to evidence the genetic changes. In addition, may be occurring gene flow with populations of nearby fragments, which is maintaining... (Complete abstract click electronic access below)

Globalização, estado-nação e organização da sociedade civil

The questions that guide this article deal with the nation-State configuration and civil society organization, as well as the contours of the relation between both in the globalization context. As a qualitative change of internationalization, globalization brings to the social sciences field the discussion about its social impacts and the problematization about extinction of State. Thus, the article is guided by the debate between determined authors that deal with the analysis about new strategies of the State action, in order to understand where national States go, seeking to adapt themselves to the new context of Capital globalization.

Acompanhamento psicológico de criança com problema de sono: um relato de caso

Difficulties with sleep are frequent in the pre-schooler children. The aim of this study was to present a case report of behavioural intervention by parental guidance to sleeping problems in a pre-schooler child. Participated in this study a four years old boy that had difficulties to sleep without the presence of his parents and his mother who was oriented through a parental program. The program of intervention was composed by five sessions in which the mother acquired education about the child’s sleep, received orientation about the establishment of time and routine to sleep and about the use of techniques (extinction and positive reinforcement) for the improvement of the sleep difficulties. The sleep and behaviour were evaluated in four periods (pre-treatment, post-treatment, one and six months follow up) according to the following instruments: 1) UNESP Scale of Habits and Hygiene of the Sleep – Children Version, 2) Scale of Sleep Disorders for Children and Teenagers, 3) Child Behavior Checklist (CBCL 1,5-5) and 4) sleep diary. The results showed that after intervention the child developed independent sleep, reduced the bed resistance and showed improvement in daily behaviors. To conclude: a behavioral intervention by parental guidance was effective to sleep problems of the child.

Novo substrato para o cultivo de orquídeas: estudo do seu potencial de uso em plantas de Laelia pulcherrima

The use of new substrates, which do not lead to extinction of important species such as xaxim, has gained special attention to the cultivation of ornamental and exotic plants. This study aimed to evaluate the potential of using corn cob as substrate for growing orchids. Thus, we used plants of Laelia pulcherrima grown in pine bark (control) and corn cob. We evaluated the development and physicochemical characteristics. We assessed also the benefit of fertilization for the development of this species in both substrates. The corn cob had higher nutrient contents and higher water retention capacity than pine bark, as well as pH and porosity more appropriate. Plant development of L. pulcherrima on the cob was comparable to that obtained with pine and the use of fertilizer promoted the best growing, especially when the substrate used was the cob. Thus, it is recommend to use the same for the cultivation of this orchid.
