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.

Na segunda metade do século passado iniciava-se um movimento revolucionário no cenário mundial da saúde mental: a Reforma Psiquiátrica. No mesmo momento nascia a proposta das Comunidades Terapêuticas, que mais tarde se tornaria um modelo consagrado de atendimento para a dependência do álcool e outras drogas. Por outro lado, com o alarmante crescimento deste problema no Brasil, assim como pela ausência de políticas públicas que dessem conta do problema, houve uma indiscriminada proliferação de locais de internação para dependentes químicos que, mesmo se autodenominando como Comunidades Terapêuticas, em nada se assemelham ao modelo inicial proposto. Estes locais apresentam práticas desumanas e iatrogênicas, muito semelhantes às criticadas pelo movimento da Reforma Psiquiátrica, o que tem provocado o descrédito para com o modelo das Comunidades Terapêuticas. Este artigo tem como objetivo demonstrar, através de pesquisa bibliográfica, como as bases conceituais e metodológicas da Reforma Psiquiátrica se assemelham profundamente as do movimento das Comunidades Terapêuticas, tendo surgido na mesma época e pelo mesmo motivo, e como a falta de regulamentação dos locais de internação para dependentes químicos no Brasil tem contribuído com o atual descrédito deste modelo.

Better knowledge of the anthropogenic soils can help create future scenarios for the Amazon region through information that supports the sustainable planning. The aim of this study was to evaluate the spatial variability of soil physical anthropogenic and not anthropogenic in the region of Manipur, AM. In the study area we selected two, one with no anthropogenic soils (native forest) and another with anthropogenic soils (black earth archaeological). In each area, we established a grid measuring 70 x 70 m and the soils were sampled at the points of intersection of the grid with regular spacing of 10 by 10 feet, making a total of 64 sampling points in each landscape. Soil samples were collected at a depth from 0.0 to 0.10 I did the analyzes physical (texture, bulk density, macroporosity, microporososidade, porosity and aggregate stability). Then, the data were subjected to descriptive statistics and geostatistics. It was found that the anthropogenic and non-anthropogenic soils showed different behaviors in relation ace their spatial structures. The spatial variability that prevailed in anthropogenic and non-anthropogenic soil was moderate and weak indicating that these soils are strongly linked to changes in the soil by extrinsic factors. The soil was observed anthropogenic best results for total porosity, microporosity and bulk density, showing superior characteristics compared for agronomic soil not anthropogenic. And the range of values found in the above two areas were used in the mesh, showing greater spatial continuity in these environments.
