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

Levantamento da mastofauna terrestre de médio e grande porte em três fragmentos de mata na Fazenda Experimental Lageado - Botucatu, SP

The present study aimed to survey the medium and large land mammals in three fragments at the Fazenda Experimental Lageado - UNESP/Botucatu, through the method of sand plots. 48 plots were used in total, 16 on each track. The paw prints found were photographed and identified from specific guides. 12 different species of mammals were found, these, 7 were classified at the level of species belonging to 9 families and 6 orders. The most representative order was Carnivora. Most of the species found have a generalist or omnivore habit, which can be related with the degree of the forest fragmentation. The only fragment of natural forest (semideciduous), presented the fewer numbers of species, which can be explained due to its isolation. The other fragment, which has near highway and other large fragment (Fazenda Experimental Edgárdia) was the most representative fragment, demonstrating the importance of nearest fragments to the continuity and survival of medium and large mammals

Filoctetes de Sófocles: o espaço e o labor humano

This article analyses the transformations of spatial references in Sophocles’Philoctetes. As we can see, instead of being cristalized in formulas and conventions, Ancient Greek Theater has renewed itself constantly, by experiencing different ways to correlate audience and events on stage.

A escolarização da literatura infantil nos anos iniciais do ensino fundamental: um processo subsidiário aos fins pedagógicos

Literature is a treasure for humanity and for the school. It causes psychological function of the individual, inserts it in the context of various cultures and historic moments, and, by having formative nature, School and Literature are intrinsecally related institutions. But literature is not the end of the first teaching, while the school has the purpose of teaching literature. Literature is not a source of good leads standards; have to be educated without this process to misrepresent. Thus, it was estalished is to investigate the inadequacy of schooling of Children's Literature pointed out by Soares in 2006, is still reality that becomes present in school or if there was any change in that status. Specific objectives were established: 1)Scanning separately in each of the books education system, from first to fifth grade of elementary school, according to the following categories involving education of literary reading: selection of genres and authors; presentation of these genres and no change from one genre to another; 2)analyze the way children's literature is presented by note-books analyzed education system develop the sensitivity of the student for pluris-signification and expressiveness of literary language, while fulfilling its social function and knowledge; 3)review the comprehension activities of literary reading proposed by notebooks to seize their educational goals. Therefore, we carried out basic theoretical research, demonstrating the functions of literature and the teaching of literature in school, and documentary research. Were analyzed 20 documents (the system apostilled notebooks), paying attention to classwork it to him of genres, authors and works chosen to be worked out, observing the cases of texts fragmentation and transport the genre to the page of the notebook system apostilled, and investigating the goals of literary reading instruction through the analysis of comprehension activities. The data received quantitative...

Impaired protamination and sperm DNA damage in a Nellore bull with high percentages of morphological sperm defects in comparison to normospermic bulls

The routine semen evaluation assessing sperm concentration, motility and morphology, does not identify subtle defects in sperm chromatin architecture. Bulls appear to have stable chromatin, with low levels of DNA fragmentation. However, the nature of fragmentation and its impact on fertility remain unclear and there are no detailed reports characterizing the DNA organization and damage in this species. The intensive genetic selection, the use of artificial insemination and in vitro embryo production associated to the cryopreservation process can contribute to the chromatin damage and highlights the importance of sperm DNA integrity for the success of these technologies. Frozen-thawed semen samples from three ejaculates from a Nellore bull showed high levels of morphological sperm abnormalities (55.8±5.1%), and were selected for complementary tests. Damage of acrosomal (76.9±8.9%) and plasma membranes (75.7±9.3%) as well as sperm DNA strand breaks (13.8±9.5%) and protamination deficiency (3.7±0.6%) were significantly higher compared to the values measured in the semen of five Nellore bulls with normospermia (24.3±3.3%; 24.5±6.1%; 0.6±0.5%; 0.4±0.6% for acrosome, plasma membrane, DNA breaks and protamine deficiency, respectively) (P<0.05). Motility and percentage of spermatozoa with low mitochondrial potential showed no differences between groups. This study shows how routine semen analyses (in this case morphology) may point to the length and complexity of sperm cell damage emphasizing the importance of sperm function testing.

Avaliação dos fragmentos florestais do município de Jaboticabal-SP

Este estudo foi conduzido no Município de Jaboticabal, SP, com o objetivo de avaliar a evolução temporal e o número de fragmentos florestais no período de 29 anos, utilizando-se técnicas de sensoriamento remoto e fotointerpretação. Para a elaboração dos mapas foram utilizadas Cartas do IBGE de 1971 e fotografias áreas de 2000. Os resultados apontaram diminuição das áreas de floresta. em 1971, o município apresentava 3,63% da área total com fragmentos florestais, e em 2000 observou-se, apenas, 1,55% dessa área. Tal fato ocorreu tendo em vista o avanço de práticas agrícolas com predominância da cultura de cana-de-açúcar. A porcentagem de fragmentos florestais em 1971, com áreas menores que 10 ha, era de 46,72%, já em 2000 esse número passou para 78,51%, concluindo-se um processo de fragmentação acentuado (31,79%) no período analisado. Os fragmentos florestais com maior extensão em 1971 se apresentaram extremamente fragmentados em 2000. Aproximadamente 60% dos fragmentos, nas duas épocas, apresentavam forma alongada, indicando alta relação perímetro/área.
