RESUMO -(Relação entre a presença de vegetação herbácea e a regeneração natural de espécies lenhosas em pastagens abandonadas na Floresta Ombrófi la Densa no Sul do Brasil). A conversão de áreas fl orestais em pastagens constitui uma das atividades que mais degradam a Floresta Ombrófi la Densa. Neste estudo, avaliaram-se áreas de pastagens abandonadas há oito, 14, 48, 50 e 96 meses, em Antonina (Estado do Paraná, 25°19'15'' S e 45°24'24'' W), com o objetivo de verifi car se a presença da cobertura herbácea diminui a regeneração natural das espécies arbóreas. Foram identifi cadas as espécies e avaliada a biomassa de espécies herbáceas (em 24 parcelas de 1 m²) e volume das espécies lenhosas (altura igual ou superior a 1 m; 24 parcelas de 25 m²). Nas cinco áreas estudadas foram amostradas 59 espécies herbáceas (1.062 indivíduos), das quais, a maioria (95%) era exótica (incluindo Brachiaria decumbens e B. humidicola). Para a comunidade de hábito arbustivo-arbóreo, foram amostradas 104 espécies (2.234 indivíduos). Houve signifi cativa modifi cação fl orística e estrutural da vegetação nos primeiros quatro anos após o abandono das pastagens. O desenvolvimento da vegetação lenhosa foi inversamente relacionado à presença de espécies herbáceas, o que sugere que a cobertura vegetal promovida pelas ervas, principalmente B. decumbens, seja um dos fatores que infl uenciam negativamente a regeneração natural. Estes resultados sugerem que práticas de manejo que incluam a remoção ou redução dos efeitos de Brachiaria spp sejam necessárias na restauração de pastagens abandonadas.

We analyzed pastures abandoned for 8, 14, 48, 50 and 96 months in Antonina (Paraná state; 25°19'15'' S; 45°24'24'' W) to verify if herb cover reduces the natural regeneration of the Atlantic forest. We identifi ed species and assessed shoot biomass of herbaceous species (in 24 1 m² plots), and calculated the volume of all woody species (height ≥ 1m; in 24 25 m² plots). We collected 59 herbaceous species (1,062 individuals) most of which were allochthonous species (95%), including Brachiaria decumbens and B. humidicola. We also sampled 104 woody species (2,234 individuals). There were signifi cant fl oristic and structural changes in the community during the fi rst four years since the pasture was abandoned. Woody vegetation development was negatively related to herb species' biomass, suggesting that grasses (B. decumbens) inhibited forest regeneration. Our results suggested that management, including Brachiaria spp removal, is necessary for the restoration of abandoned pastures in the Atlantic Forest region.
Replacing the Brazilian Atlantic Forest by pastures has caused a strong impact on this biome. Hence, to evaluate the forest recovery after removing disturbance is a key factor to conserve biodiversity. In this study we analyzed changes in forest structure in five abandoned pastures in southern Brazil, aiming to verify the direction and rate of structural and functional changes in the early succession. The abandoned pastures (by periods of 8, 14, 48, 50 and 96 months) were colonized mainly by trees, animal-dispersed and pioneer species. The data showed that the forest structure was quickly changed with an increase in tree abundance, stem volume and species richness. It indicates that in low fragmented landscapes, such as the northern littoral of Parana State, the resilience of the Atlantic Forest is relatively high and assisted regeneration may be an option to biodiversity conservation strategies.
The aim of this study was to evaluate the diversity of Meliponini and anothers Apiformes (Apidae sensu lato) from a Cerrado fragment and its surrounding. Malaise traps were installed in a pasture near a fragment of Cerrado and its surrounding, from October to December 2010. Samples were collected at seven-day intervals and preserved in Dietrich solution. The apiforms specimens from each sample were separated in morphospecies and sent to identification. The tribe Meliponini was the most abundant in open areas of pasture than in the Cerrado fragment. The Meliponini species present were Trigona gr. fulviventris, Paratrigona lineata, Trigona recursa, Partamona sp, Trigona spinipes, Trigona gr. hyalinata, Trigona gr. fulviventris, Tetragonisca fiebrigi, Tetragona clavipes, Frieseomelitta cf. flavicornis, Lestrimelitta rufipes. The dominant species was Paratrigona lineata, comprising 82.47% of all species collected.
Resumo O presente trabalho pretende apresentar ao leitor a importância do Museu José Antônio Pereira como patrimônio histórico e cultural de Campo Grande, Mato Grosso do Sul. Partiu-se do pressuposto de que os museus devem colocar-se como locais para a formulação de um pensamento crítico Para isso, foram realizadas observações durante o estágio não-obrigatório da graduação em Licenciatura em História pela Universidade Federal de Mato Grosso do Sul. Observou-se a potencialidade do museu em dialogar com o público realizando atrelamentos entre a educação reflexiva e o lazer. Este trabalho almeja promover a salvaguarda dos acervos e a valorização das ações educativas nos museus. Palavras-chave: Patrimônio. Educação. Museus. KNOWING THE MUSEUM JOSÉ ANTONIO PEREIRA: a historical heritage of Campo Grande-MS Abstract The present work intends to present to the reader the importance of the Museum José Antônio Pereira as historical and cultural patrimony of Campo Grande, Mato Grosso do Sul. It was assumed that museums should be placed as places for the formulation of critical thinking (RAMOS, 2008). For this, observations were made during the non-compulsory stage of the undergraduate degree in History by the Federal University of Mato Grosso do Sul. It was observed the potentiality of the museum in dialoguing with the public performing attitudes between reflexive education and leisure. This work aims to promote the safeguarding of collections and the valuation of educational actions in museums.
