Herbivoria em Bauhinia rufa (Leguminosae: Caesalpinioideae) em fragmentos de cerrado

Herbivory is the basal link among the trophic chains and therefore has great importance in the energy flow in the ecosystems. However, the ecological interactions have been changed due to the process of fragmentation that has occurred in the cerrado. Thus, our objective was to evaluate the herbivory and the presence of possible constituents of defense in leaves of Bauhinia rufa in two cerrado fragments of different sizes . We evaluated in both of them species richness and abundance of herbivores as well absolute herbivory ( n = 25 plants / fragment ) . Through histochemical tests and scanning electron microscopy we verified the constituents of defense. The difference between the herbivory in the fragments was not statistically significant ( t = -1.387 , p = 0.166 ) . However , we found a higher abundance of morphotypes of herbivores in the smaller fragment. We detected chemical and physical constituents that may confer protection to the plant at all stages of leaf development. Although several publications have indicated that small fragments have a higher susceptibility to changes, our study revealed no effect of fragment size on the absolute herbivory, suggesting that there are other factors acting more strongly and maintaining this type of interaction in these ecosystems

Fronteiras nas Américas: tamanho e composição dos domicílios rurais no oeste do Brasil e EUA na primeira metade do século XIX

The study of the size and composition of the rural household in tradicional societies in transition to modern ones is very useful as a tool in order to understand forms and organizations of the domestic groups and their possibilities of survival, social mobility e developing strategies of material accumulation. The aim of this article is to compare the size and composition of the rural households in the frontier regions of the Americas: the northwest and southwest of U.S.A with the southwest of São Paulo province in Brazil. The findings are surprising in comparative perspective, as the mean size of the American households were very high in relation to the brazilian ones. The sources used in this research are the manuscript census of the U.S.A and Brazil.

Páginas da copa: o mundial do Brasil na Folha de S. Paulo e Estado de S. Paulo

O futebol nos dias de hoje representa algo muito maior do que um exercício físico ou uma atividade de descontração. Ele desempenha um papel dentro da sociedade que extrapola as perspectivas do jogo. Reduzir a análise sobre o futebol profissional apenas ao aspecto lúdico do esporte também diminui a concepção sobre o que ele realmente representa. Nos bastidores do espetáculo futebolístico existe um universo de atos políticos que abrangem diversas esferas do poder que por sua vez auxiliam na execução do esporte como um evento esportivo com milhões de espectadores. Uma das razões para que o âmbito político do esporte seja menos conhecido do que as táticas dos técnicos ou dribles dos jogadores é a cobertura feita pelos meios de comunicação. No decorrer de sua existência, o futebol se transformou em um evento globalizado que envolve em sua órbita muito mais do que apenas o aspecto esportivo. Com os anos, o esporte foi se firmando em diversos países como produto cultural e até mesmo ferramenta política. O que se vê contudo é a sobreposição midiática do jogo sobre a sua verdadeira estrutura. O entretenimento trazido pelo esporte ganha as páginas enquanto o jogo político que sustenta a realização do mesmo recebe uma atenção mais discreta das mídias. A proposta deste trabalho é analisar como foi feita a divulgação de notícias referentes à Copa do Mundo de 2014, que será realizada no Brasil, nos jornais Folha de S.Paulo e O Estado de S. Paulo durante o ano de 2012 através dos seus cadernos de esportes. O objetivo é compreender qual é o teor e a intensidade da cobertura sobre os fatos políticos que ajudam a dar forma ao evento mais importante do futebol. Acontecimentos desta proporção exigem preparação do país, o que implica em um trabalho em conjunto entre o Governo Federal e FIFA. Pretende-se analisar a contextualização feita pelos jornais em relação ao esporte ao seu aspecto esportivo, podendo...

Degradabilidade e digestibilidade de híbridos de milho em função do estádio de colheita, tamanho de partícula e processamento por meio do esmagamento na ensilagem

During the process of silage corn, should take into consideration some aspects that will result in better utilization. The aim of this study was to evaluate the degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and starch digestibility and in vitro dry matter (DM) of silage corn hybrids due two textures, three stages of harvest, three particle sizes and processing by crushing. After harvesting and chipping, part of the material was crushed and then ensiled and sealed for 45 days. After opening the silos, analyzed the degradability in the incubation time of 20 hours using the technique in situ macro bag. The experimental design was a randomized split plot. The DM degradability was influenced only by the effect of stages of sampling used. The degradability of CP showed interaction between processing and particle size (Tp), noting that increased degradation due to processing. For NDF degradation significant interaction of factors, hybrid and processing, similar to the degradation of starch. The IVDMD was influenced by the effects of hybrid, stadium, Tp and processing. It can be concluded that benefits were higher with the use of processing associated with more advanced stages of harvest, in larger particle sizes.

Estudo histomorfométrico do processo de cicatrização óssea em defeitos cirúrgicos de tamanho crítico em calvárias de ratos preenchidos com polímero de mamona

Objectives: The aim of this study was to evaluate the behavior of the polymer histomorphometrically castor during the healing process of defects of critical size calvarial preparations in rats. Materials and Methods: Twenty animals underwent a surgical procedure that was to be held in the calvaria of each animal a critical defect of 8 mm in diameter with a drill trephine. The rats were divided into two groups according to the following procedures: group C received no treatment and the bone defect site was filled with blood clot, group M, the bone defect was filled with castor oil polymer particles. The animals were sacrificed 180 days after the surgical procedures. After routine laboratory procedures the specimens were subjected to analysis histomorphometric. Results: In groups C the newly formed bone tissue was well developed, with adjacent areas of osteoid matrix rich in osteoblasts, and restricted to the vicinity of the edges of the defect. In animals of group M was observed newly formed lamellar bone tissue restricted to the vicinity of the defect edges and particles of polymer Castor distributed throughout the defect. There was a higher percentage of newly formed bone area was statistically significant in group C compared to animals in group M. Conclusions: Within the limits of this study can conclude that the castor oil polymer is biocompatible and had kept the area during the healing of critical size defects in surgically prepared rat calvariae

A proporção de plasma rico em plaquetas/enxerto ósseo autógeno pode influenciar o reparo ósseo de defeito de tamanho crítico: estudo radiográfico em calvária de ratos

Introduction: It has been suggested that bone grafts combined with platelet rich plasma (PRP) present greater density than bone grafts without PRP after healing process. However, this result may depend on proportion PRP/autogenous bone (AB) graft used. Objective: The purpose of this study was to analyze radiographically the influence of the proportion PRP/particulate autogenous bone (AB) graft on bone healing in surgically created criticalsize defects (CSD) in rat calvaria. Material and method: 50 rats were divided into 5 groups: C, AB, AB/PRP-50, AB/PRP-100 and AB/PRP-150. A 5 mm diameter CSD was created in the calvarium of each animal. In Group C the defect was filled by blood clot only. In Group AB the defect was filled with 0.01 mL of AB graft. In groups AB/ RP-50, AB/PRP-100 and AB/PRP-150 the defects were filled with 0.01 mL of AB graft combined with 50, 100 and 150 µL of PRP, respectively. All animals were euthanized at 30 days post-operative. Standardized radiographic images of the rat calvaria were obtained using Digora System (Soredex, Finland). The images were evaluated by three examiners using scores that indicated the percentage of radiopacity of the defect. The obtained data were subjected to statistical analysis (Kruskal-Wallis test, p < 0.05). Result: Group C presented radiopacity significantly lower than groups AB, AB/PRP-50, AB/PRP-100 and AB/PRP-150. Group AB/PRP-50 showed radiopacity significantly greater than groups AB/PRP-100 and AB. Conclusion: It can be concluded that the proportion PRP/AB graft influences bone healing in CSD in rat calvaria.
