This study aimed to determine how the richness and composition of ant species behaves with changes in the recovery process of a gully erosion. The study area has 0.9 hectares subdivided into three sections called sector: A, B and C. For the definition of the sectors, erosive and natural restoring were taken as the base level of activity. Four transects were laid systematically throughout the area and surrounding compound with forest and grassland. Each transect had three pitfall trap ten meters apart from each other, with catches of ants were held in rainy and dry seasons. Analysis of variance was applied to compare the number of ant species per plot captured and Scott-Knott test 5% for comparison of means. To verify the similarity of species between environments it was performed an analysis of similarity (ANOSIM) and ordering of environments a Nonmetric Multidimensional Scaling (NMDS). We captured 74 species of ants inside and around the gully erosion. The more degraded environment and initial stage of regeneration, showed greater richness of ant species. The composition of ant species was different between the recovery environments and around. The parameters of ant communities analyzed, richness and composition species were influenced by the regeneration of the area, indicating that ants can be used as bioindicators of gullies recovery.

The aim of this research was to analyze the composition and structure of the plant community in four phytophysiognomies at Pantanal Poconé-Mato Grosso, assuming that each sample group is a type of community, and there would be a corresponding group of species that characterize that community. We set up five plots of 50 × 50 m and subdivided each one into subplots of 10 × 10 m. In each subplot, individuals with CAP (circunference at breast height) > 10 cm were sampled. To check the structural and floristic similarity of the five vegetation types the unweighted averages grouping method was used - UPGMA, with Jaccard's coefficient and Bray-Curtis, respectively. DCA ordination of plots was used for inundation gradient analysis and TWINSPAN indicator species groups for the three strata. In the four areas 55 species belonging to 30 families were sampled. The UPMGA indicated floristic and structural differences between cambarazal, savanna types and campo de murundu and similarity between the semideciduous formations. The DCA separated the vegetation types according to the level of flooding and TWINSPAN indicated the existence of typical species for each vegetation type. In the Pantanal, some species may be restricted to certain types of vegetation, and these species can be used as indicators of the effect of flooding and possible changes in flood pulse dynamics in plant communities.

AIM: In this study, we evaluated and compared community attributes from a tropical deforested stream, located in a pasture area, in a period before (PRED I) and three times after (POSD I, II, and III) a flash flood, in order to investigate the existence of temporal modifications in community structure that suggests return to conditions previous to the flash flood. METHODS: Biota samples included algae, macrophytes, macroinvertebrates, and fish assemblages. Changes in stream physical structure we also evaluated. Similarity of the aquatic biota between pre and post-disturbance periods was examined by exploratory ordination, known as Non-Metric Multidimensional Scaling associated with Cluster Analysis, using quantitative and presence/absence Bray-Curtis similarity coefficients. Presence and absence data were used for multivariate correlation analysis (Relate Analysis) in order to investigate taxonomic composition similarity of biota between pre and post-disturbance periods. RESULTS: Our results evidenced channel simplification and an expressive decrease in richness and abundance of all taxa right after the flood, followed by subsequent increases of these parameters in the next three samples, indicating trends towards stream community recovery. Bray-Curtis similarity coefficients evidenced a greater community structure disparity among the period right after the flood and the subsequent ones. Multivariate correlation analysis evidenced a greater correlation between macroinvertebrates and algae/macrophytes, demonstrating the narrow relation between their recolonization dynamics. CONCLUSIONS: Despite overall community structure tended to return to previous conditions, recolonization after the flood was much slower than that reported in literature. Finally, the remarkably high flood impact along with the slow recolonization could be a result of the historical presence of anthropic impacts in the region, such as siltation, riparian forest complete depletion, and habitat simplification, which magnified the effects of a natural disturbance.

Este estudo tem como tema o teste de padrão de frequência e de duração no Brasil e como objetivo revisar e explanar sobre a avaliação do processamento auditivo temporal no Brasil, mais especificamente sobre os testes tonais de ordenação temporal (teste de padrão de frequência e duração). Para atingir tal objetivo foi realizado um trabalho de revisão sistemática da literatura em periódicos nacionais, acessados eletronicamente na base de dado Scielo e Lilacs, sem restrição ao ano de publicação. A pesquisa foi estruturada por meio dos descritores: processamento temporal, processamento auditivo temporal, testes temporais, testes tonais de padrão de frequência e testes tonais de padrão de duração, percepção auditiva e testes auditivos. A pesquisa retornou 33 publicações nacionais sendo 28 artigos de periódicos, uma dissertação de mestrado e quatro teses de doutorado. Com isso, pode-se perceber que a utilização de testes que avaliem a habilidade de ordenação temporal no Brasil é recente, sendo notável o aumento significante das publicações nos últimos cinco anos. Desta forma, o emergente conhecimento possibilitado pelo acesso aos testes no Brasil permite ampliar um campo de pesquisa a todos os profissionais comprometidos com este tema.

The use of the adjective radical to identify the variety of behaviorism proposed by Skinner is current nowadays. However, historically, this qualifier was not exclusively applied to Skinner's proposal and its polysemy tends to generate inaccuracies in the interpretation of what characterizes Skinner's Radical Behaviorism. This article aims to clarify the most appropriate sense of radical when applied to Skinner's behaviorism by means of four articulated activities: (1) the description of the etymological origins of the word radical and its different meanings in Portuguese, Spanish and English, (2) a reconstruction and analysis of the evolution of a historical setting that culminated in the use of the term in the behaviorist context, (3) an analysis of the main meanings of radical when associated with behaviorism, (4) an examination of some ways in which the use of the term associated with behaviorism is consistent, and the current and future implications for Radical Behaviorism and Behavior Analysis in a scientific context.

PurposeTo characterize and compare the performance of malnourished children and normal children in auditory processing. MethodThe sample comprised 30 children from five to ten years old, both genders, being 15 malnourished children (G1) and 15 children with adequate nutritional status, as a control group (G2). The groups were paired according to gender, age and grade level. Both groups underwent peripheral and central auditory assessment, noting that malnourished children had higher changes in the skill of sequencing score for verbal and nonverbal when compared to normal children, and the same occurred in closing skills and background figure. ResultRegarding the degree of auditory processing disorder, it was more severe in malnourished children. ConclusionChildren with malnutrition have higher frequency alterations in auditory abilities when compared to normal children, being the temporal ordering skills, auditory memory, selective attention, figure-ground and closing the most affected skills.

Cardoso Island, settled in the south of paulista region, is characterized by its ecological importance due to the great biodiversity of Mata Atlântica and for accommodating several kinds of ecosystems as mangroves, which were considered by UNESCO as human natural ownership. The mangroves are among the most important marine ecosystems, known as warranty of biological productivity and diversity and supply of food and economical resources to the local population. Although the island has been transformed in a state park for preservation, it hasn’t become free from environmental impacts made by antropical activities. This way it was proposed a rebuilt of an evolutionary process in the region, having as an objective to subsidize programs of environmental conservation and planning , aiming to a sustainable development. For this it was used a isobasis methodological analyses where by the drainage channels and its confluences makes relative maps to the different base levels represented by the isobasis, characterizing itself by an attempt to rebuilt the preterit local landscape. There were elaborated eight maps referring to four orders of confluences met in the region of Cardoso Island and round it where you can conclude it is about an appropriate methodology to rebuilt preterits environments that specially aim to actions of environmental planning and conservation.

Among several sites in Brazil, where the local human community develop a consistent knowledge on the environment they live, there is Cananeia local authority in south coast of Sao Paulo. The history of Cananeia is presented as an ancient human occupation, which, nowadays, culminates in 12000 habitants that survive from tourism and fishing. Considering the great importance of the knowledge about plant toxicity, the objective of this work is to develop a study with the residents and its focus is their acquaintance with toxic plants, which occur on contiguous areas. After a preliminary recognition field work, the local authority under study was subdivided into two areas for sampling, characterized by the different levels of human occupation: (A) Island area, more occupied, and (B) Continental area, less occupied. The semi-structured interviews were conducted in both areas according to the “snow ball” method, due to the specifically interest of making comparisons. The plant species cited in the interviews were collected, herborized and identified. One proceeded quali- and quantitative analysis in order to elucidate differences between the studied areas, to establish relations among age/sex of the habitants, the cited species diversity and the practice of knowledge transmission. Were carried out 90 interviews (47 in island, 43 in continent) in which the habitants have cited 137 ethno-species. Both communities are much alike, although the manly differences were presented by the occupation and the uses of the toxic plants. At the island, were interviewed three key-informers, this fact that has not happened at the continent. It was not noticed significant statistical difference between the diversity of toxic plants knew by the habitants of both areas, but a huge dissimilarity was found. The most cited plants, especially the ornamental ones, at both areas are scientifically... (Complete abstract click electronic access below)

This monograph is aimed at reflecting the internal structure of the book Coroa da Terra (1946), the Portuguese poet Jorge de Sena (1919-1978), investigating for this, the guiding criteria for the ordering of poems. Starting from a question posed by an author paratext, we considered the possibility that the book is constituted as a unit of poetic path, in which each poem comprises a stretch of the pilgrimage undertaken by the poet toward the crown of the Earth. Moreover, from the epigraph of the book and the Preface (1960) of 1st edition of Poesia I (1961), we consider the idea that the Coroa da Terra is a search for truth, or even that the pilgrimage made by the poet is on the trail of a poetic word conscious and therefore ethically responsible. This search would set the poetic language of testimony, from which derive two other important vectors for the exegesis of poetry seniana: metamorphosis and pilgrimage. Upholding the unity of the book would be the language in dialectical flow as a formal procedure, which enables the poet be an expression in constant motion. To check the validity of our hypothesis, we conducted an analysis of four poems in sequential order (―Purgatório‖, ―Suma Teológica‖, ―Os trabalhos e os dias‖, ―Espiral‖). To them, it was added to analyze the poem ―Metamorfose‖, poem 23rd of the Coroa da Terra, which acted as a reference point and as close to the research by presenting a character's thought seniano synthesis. It was found that the idea of unity is sustained when we consider Coroa da Terra as a journey of formative poetic direction

A rápida expansão do espaço urbano no Brasil ocorreu e continua ocorrendo, geralmente, de forma desordenada e sem perspectivas imediatas de ordenação das práticas de uso e ocupação do solo. O planejamento da ocupação do espaço urbano, baseado na racionalidade capitalista, embora englobe fundamentos interdisciplinares, na prática tem sido realizado dentro de um âmbito mais restrito do conhecimento, desconsiderando aspectos fundamentais dessa dinâmica. Essa situação tem resultado em grandes transtorno e custos para a sociedade e para o meio ambiente, atingindo diretamente os sistemas de drenagens urbanos e resultando no crescimento dos eventos de cheia. Assim, o planejamento urbano vem buscando alternativas que possibilitem o alcance do desenvolvimento urbano sustentável. Neste sentido, este trabalho objetiva avaliar qualitativamente a implantação reservatórios de detenção implantados no alto curso da sub-bacia do Alto Tietê, de modo a avaliar os problemas apresentados através da realização de um inventário dos avanços atingidos na incorporação destas medidas no gerenciamento dos sistemas de drenagem nesta subbacia.
