Agroindústria canavieira e unidade de conservação: Impactos Sociais na comunidade de pescadores de Baía Formosa (RN)

The conservation unities emerged in response to the environmental damages. In the Atlantic Forest of the Brazilian Northeast, the most of the damages come from the sugar-cane agro-industry, especially by the deforestation for the introduction of sugar-cane fields and installation of the industry structure. Besides the damages over the biodiversity, there are critical social problems that affect the communities which survive using directly or indirectly the biome from the Atlantic Forest. The objective of this research is to analyze the social impacts on the fishermen of Baía Formosa/RN generated by the changes and socio-environmental transformations occurred starting the installation of a sugar-cane factory and the creation of a conservation area in the municipality of Baía Formosa/RN community. The research is based on a qualitative and diachronic perspective, for both approach, it was used the method of oral history in conjunction with the literature search and some technical and research tools such as direct observation, interview, records images and recordings . The results show that social and symbolic practices of the community in the conservation unit Mata Estrela last more strongly presented. Today fewer natural resources are used, due to factors such as limit access to forest and disappearance of some natural resources by deforestation. It is believed that the loss of free access to space for the community is the most significant negative impact, as promoted changes in the relationship of the community with the Star Forest that contributed to the fading of their social and symbolic practices. The loss of free access caused the decline in the practice of agriculture, which resulted in the loss of one of the means of social reproduction of the community

Avaliação da chuva de sementes em áreas de restinga em diferentes estágios de regeneração

This study was conducted in an area of restinga in the municipality of Silo Vicente (SP). The study aimed to evaluate the seed rain in three different conditions of regeneration. Was selected the following conditions: High Forest of Restinga in the middle stage of regeneration, an area of clearing in the same condition mentioned above and a third in early stages of regeneration. hi each condition were installed 10 seed collectors made of wood and screen with 80% of shade, supported to a height of 20cm of soil. They were evaluated monthly for one yew; the densities of seed deposited in the collector these seedlings are identified and categorized based on their dispersion syndrome and successional classes. The Area of High Forest area was carried out a phytosociological survey to identify which seedlings present in the rain could be from these areas. It was found that the densities of seedlings are relatively low compared to other formations of the Atlantic rain forest, but consistent with other studies of the same type of vegetation used in the study. Regarding dispersal syndromes and successional classes, there was prevalence of the zoocoric syndrome and species of secondary successional classes. The results indicate that the area has good ability to maintain their succession dynamics.

Vertebrados consumidos por Brycon opalinus (Pisces, Characidae) em rios do Parque Estadual da Serra do Mar, SP

A análise da alimentação da pirapitinga do sul (Brycon opalinus), peixe ameaçado de extinção de rios da Mata Atlântica da Serra do Mar na região Sudeste, revelou a ocorrência de itens alimentares incomuns. As espécies deste gênero são onívoras oportunistas e alimentam-se de itens vegetais e animais, tais como: flores, folhas, frutos e sementes e grande variedade de insetos. em três rios do Parque Estadual da Serra do Mar - Núcleo Santa Virgínia foram encontrados exemplares de B. opalinus que consumiram três itens animais incomuns, os anfíbios Hypsiboas aff. pardalis (Anura, Hylidae) e Eleutherodactylus guentheri (Anura, Leptodactylidae) e o mamífero Oligoryzomys cf. nigripes (Rodentia, Sigmodontinae). O registro do consumo destas espécies de vertebrados foi relacionado com o período de chuvas, quando o material animal ou vegetal carreado até o rio pode ser consumido por B. opalinus, mesmo que não sejam itens habituais para a espécie. A mata ripária preservada, como foi verificado nos três rios do Parque Estadual da Serra do Mar - Núcleo Santa Virgínia (SP), é de suma importância para o fornecimento de itens alimentares animais e vegetais e pela manutenção das condições bióticas e abióticas para a sobrevivência de B. opalinus.

Primeiro registro de predação de Poecilia reticulata Peters, 1859 e Phalloceros caudimaculatus (Hensel, 1868) por Noctilio leporinus (Linnaeus, 1758) (Chiroptera, Noctilionidae)

Noctilio leporinus (Chiroptera, Noctilionidae) has adaptations to piscivorous feeding habits, but also consumes crustaceans and insects. Between June 2005 and May 2006, bats were surveyed with mist nets during two evenings per month in the gallery forest of Corrego dos Tenentes, Pindorama, São Paulo State, Brazil. The objectives were to collect fecal samples and identify the fish species that were consumed by N. leporinus in this fragmented forest landscape. We documented two new fish species to its diet, the guppy Poecilia reticulata, Peters, 1859 and the "guaru" Phalloceros caudimaculatus (Hensel, 1868). Both fish species forage near the surface of water for insects and zooplankton, which is an area also utilized by N. leporinus when foraging for insects, crustaceans and fishs.

Anura, Estacao Ecologica de Jatai, São Paulo State, southeastern Brazil.

The Estacao Ecologica de Jata comprises one of the largest mesophytic semideciduous forest and savanna remnants in the state of São Paulo. However, anuran surveys on this site have not been registered in the literature. As result of an exploratory survey conducted in water bodies in the mesophytic semideciduous forest and surroundings in December 2006, we recorded 21 anuran species belonging to five families and 10 genera. These findings contribute to the knowledge of the anuran fauna associated to the mesophytic semideciduous forest of São Paulo state, Brazil.

Predação de morcegos (Phyllostomidae) pela cuíca d’água Chironectes minimus (Zimmermann, 1780) (Didelphimorphia, Didelphidae) e uma breve revisão de predação em Chiroptera

Bats are predated for some of vertebrates and invertebrates. Some opportunistic species preys these animals' prisoners in nests during procedures of capture in field. This study records the predation of Carollia perspicillata (Linnaeus, 1758) and Sturnira lilium (E. Geoffroy, 1810) for Chironectes minimus (Zimmermann, 1780) on riparian forest of the brook Talhadinho belonging of the São Paulo, São Paulo, Southeast Brazil, and also presents a lifting previous of mammalian what they present the same one behavior opportunistic predatory, discussing measures simple to avoid this type of predation.

Heavy metals in a degraded soil treated with sludge from water treatment plant

A aplicação do lodo de estação de tratamento de água (LETA) em solos degradados é uma alternativa tanto para disposição desse resíduo como para a recuperação do solo. Neste trabalho avaliaram-se os efeitos do LETA nos teores de metais pesados em um Latossolo degradado por mineração de cassiterita na Floresta Nacional do Jamari, RO, Brasil. Utilizou-se delineamento experimental inteiramente casualizado com cinco tratamentos: testemunha (n = 4); testemunha química, que recebeu apenas calagem (n = 4) e doses D100, D150 e D200 (respectivamente 100, 150 e 200 mg de N kg-1 solo na forma de LETA), aplicadas antes da calagem (n = 20). Após 30 dias da calagem, período em que o solo contido nos vasos foi mantido com teor de umidade próximo à capacidade de retenção, coletaram-se amostras de solo, que foram analisadas com relação aos teores totais e extraíveis de Fe, Cu, Mn, Zn, Cd, Pb, Ni e Cr. A aplicação de LETA aumentou os teores dos metais pesados do solo. A aplicação deste tipo de lodo em áreas degradadas pode causar impacto ambiental e, portanto, deve ser monitorada.

Classificação fitogeográfica das florestas do Alto Rio Xingu

Este trabalho propõe a inclusão da categoria Floresta Estacional Perenifólia no sistema oficial de classificação da vegetação brasileira, devido às particularidades florísticas e fisionômicas da floresta da borda sul-amazônica, que atinge maior amplitude geográfica na região do Alto Rio Xingu. Para justificar essa inclusão são apresentadas as características ambientais (clima, solo, hidrologia) e diferenças fisionômicas e florísticas entre as florestas do Alto Xingu e demais florestas ombrófilas da Bacia do Amazonas e estacionais do Planalto Central.

Fugitive species in a harlequin environment: Ants (Hymenoptera : Formicidae) and banana baits in the Amazon

A total of 9 ant species were sampled from four sites covering 2000 km in the Amazon Basin using banana fruit baits: two sites on the Jurua River, one site on the Xingu River and in a dry forest of eastern Amazon, Paragominas. Camponotus abdominalis was present in all sites, and Camponotus sericeiventris, Camponotus sp. and Crematogaster sp. were present in two sites. All other species were present in only one site. Paragominas had the highest species richness because of a higher number of site restricted species. However, Jaccard faunas similarities among sites were not significantly related with distance between sites. Mosaic diversity showed a relatively simple taxonomic composition. The strong differences of the fauna sampled at banana fruit baits from other reported Neotropical ant faunas suggests that the fauna represents widespread fugitive species in an apparently complex environment.

Persistência de mamíferos de médio e grande porte em fragmentos de floresta ombrófila mista no estado do Paraná, Brasil

The Araucaria Forest is now represented by remnants of what was a continuous area of about 200,000 km(2). Medium and large mammals inhabiting this forest have suffered the impacts from the disturbance process and environmental degradation. Thus, this study determined which medium and large mammal species still inhabit the remnants of this vegetation type in Western Parana State. Three study areas, with 520, 405 and 135 hectares, consisting of stretches of primary forest mixed with secondary forest, were considered for mammal inventory. The evidence of mammals was verified directly (views) and indirectly (traces, trichology and interviews with local dwellers). It was recorded 32 species (including one exotic and two small ones), belonging to eight orders and 18 families. Nine animals of these species are at risk of extinction in the Parana State and five configure with insufficient data in the List of Endangered Species of the state. The results of this study indicate the great importance of these forest fragments in the conservation of several medium and large mammals in the Araucaria Forest of Parana State. Nevertheless, due to the negative pressures that these areas have been suffering, immediate and concrete public actions are required to ensure the maintenance of these mammal populations.
