Helmintofauna associada à Physalaemus cuvieri proveniente de duas áreas de Mata Atlântica

From November 2009 to January 2010 we collected 22 specimens of Physalaemus cuvieri from a preserved area (State Park of Serra do Mar - Núcleo Santa Virginia, São Paulo State, Brazil) and 21 specimens from a disturbed area with habitat fragmentation (rural areas – São Luis do Paraitinga municipality, São Paulo State, Brazil) to compare the helminth fauna associated to this anuro species. The helminth fauna is composed by the nematodes of family Cosmocercidae, Physaloptera sp. and Rhabdias sp. as well as Acanthocephalus saopaulensis in the individuals from the preserved area; the individuals from the fragmented area also presented nematodes of family Cosmocercidae, Physaloptera sp. and Rhabdias sp. as well as Oswaldocruzia subauricularis and the monogenea Polystoma cuvieri. Prevalence, mean intensity of infection, mean abundance, mean richness, importance index (IE) and Dominance frequency were calculated in both localities, but there was no statistical diference. The diversity of helminth species was calculated by Shannon, Brillouin and Berger-Parked index, and by using Shannon diversity t-test we compared helminths diversity associated with anfibian from this two localities

Avian communities in woodlots in the Parque das Neblinas, Bertioga, São Paulo, Brazil

Parque das Neblinas (PN) is a 2,800 ha nature reserve contiguous with an Atlantic Forest fragment known as Parque Estadual da Serra do Mar located in the municipality of Bertioga, in the state of São Paulo, Brazil. The area originally contained Eucalyptus trees grown for paper pulp production. The aims of the study were the following: (1) to characterize the diversity of the bird community in PN; (2) to compare bird species observed in PN to species found in the Atlantic Forest; and (3) to list the percentages of species endemic to the Atlantic Forest and present in PN. Quantitative surveys used the point count method. The number of avian species recorded in PN totaled 222, of which 150 (66.4%) were associated with forest environments, 66 (29.3%) with open areas, and 10 (4.3%) with aquatic environments. The quantitative survey recorded 141 species and 2,527 contacts in 120 samples for an average of 21.05 contacts per sample. The general diversity index was H´=3.82. The study identified 15 bird species that actively participated in mixed flocks and 25 species endemic to Atlantic Forest, two of which present some kind of concern relating to conservation. Areas with Eucalyptus trees and a dense understory displayed the greatest bird species diversity, as opposed to areas with less developed or non-existent understories.

Habitação e gestão ambiental em áreas de mananciais: o caso do município de Santo André (SP)

Este artigo tem como objetivo levantar e discutir as ações de gestão ambiental e sua interface com a questão habitacional junto à área administrada pela Subprefeitura de Paranapiacaba e Parque Andreense, Santo André-SP, no biênio 2007-2008. O foco do trabalho é a capacidade política e institucional do município criada para tratar de tais questões. Os métodos usados foram pesquisa documental, bibliográfica e de campo, com entrevista a gestores do município. A pesquisa identificou que o município conta com propostas com grande potencial de contribuição para a melhoria da qualidade ambiental e habitacional na área de mananciais, principalmente por seu caráter de integração entre planejamentos. O estabelecimento de conselhos com participação de várias pastas representa um potencial elemento de integração nas ações desses órgãos, permitindo o compartilhamento de temas pertinentes ao longo do desenvolvimento das agendas de forma contínua. Quanto à recuperação urbana e ambiental dos loteamentos irregulares, é possível afirmar que os parâmetros urbanísticos e a definição do uso e ocupação do solo estão intimamente relacionados à qualidade ambiental e precisam ser construídos em conjunto por profissionais da área de urbanismo e da área ambiental, e discutidos com a comunidade local. O formato de gestão na área de mananciais, foco deste estudo de caso no município de Santo André, representa um significativo passo na construção da integração entre os sistemas de gerenciamento de recursos hídricos e de planejamento urbano/metropolitano.

OCUPAÇÃO SUSTENTÁVEL DO ENTORNO DO PARQUE DO SUMIDOURO

A preservação ambiental ganhou respaldo a partir do momento que a degradação do meio ambiente passou a interferir na qualidade de vida humana. Para controlar os danos gerados na natureza foram criados os parques. No Brasil a criação de um parque implica no isolamento das comunidades que antes ocupavam as suas áreas. Como não ocorre um processo de envolvimento, mas de isolamento as reservas naturais são ilegítimas frente aqueles que vivem no seu entorno. O Parque Estadual do Sumidouro sofre com essa falta de legitimidade e é o objeto de estudo desse trabalho. O objetivo da pesquisa realizada é demonstrar como o sucesso de uma ação de preservação ambiental depende da educação ambiental e de políticas sociais que promovam a participação da comunidade de forma sustentável. A fundamentação da pesquisa foi feita baseada na legislação e autores da área. Para o resultado alcançado foram utilizadas técnicas exploratórias, descritivas e explicativas, mediante métodos de pesquisa de trabalho de campo e bibliográfica.

Complicações imediatas e tardias após cirurgia de reservatório ileal na polipose adenomatosa familiar

BACKGROUND: Restorative proctocolectomy is the procedure of choice to treat familial adenomatous polyposis, however it can be associated to short-term and long-term postoperative complications. AIM: To evaluate the occurrence of complications related to the surgical treatment of familial adenomatous polyposis with ileal pouch technique. METHODS: Retrospective study of 69 patients with familial adenomatous polyposis after rectocolectomy with ileal reservoir between 1984 and 2006, operated on Coloproctology Group, Medical Sciences Faculty, State University of Campinas, Campinas, SP, Brazil. The median follow-up period was 82 (2-280) months. Data obtained were surgical techniques and postoperative complications. RESULTS: The morbidity and mortality were 63.8% and 2.9%, respectively. The most frequent complications were small-bowel obstruction (17.4%), anastomotic stricture (15.9%) and pelvic sepsis (10.1%). Acute ischemia of the ileal pouch (4.3%), pouchitis (2.9%) and ileal pouch-related fistula (2.9%) had poorer frequency than others. CONCLUSIONS: The morbid-mortality was similar to the literature?s data and it is acceptable for a complex surgery in two terms like the ileal reservoir-anal anastomosis. The small-bowel obstruction was the most frequent complication. However, ischemia of the reservoir, pouchitis and pelvic sepsis were important complications and was related to the failure of the ileal reservoir.

Resultados da cirurgia de reservatórios ileais em pacientes com doença de Crohn

BACKGROUND: Total rectocolectomy and ileal pouch-anal anastomosis is the choice surgical procedure for patients with ulcerative colitis. In cases of Crohn's disease post-operative diagnosis, it can be followed by pouch failure. AIM: To evaluate ileal pouch-anal anastomosis long-term outcome in patients with Crohn's disease. METHODS: Between February 1983 and March 2007, 151 patients were submitted to ileal pouch-anal anastomosis by Campinas State University Colorectal Unit, Campinas, SP, Brazil, 76 had pre-operative ulcerative colitis diagnosis and 11 had post-operative Crohn's disease diagnosis. Crohn's disease diagnosis was made by histopathological biopsies in nine cases, being one in surgical specimen, two cases in rectal stump, small bowel in two cases, ileal pouch in three and in perianal abscess in one of them. The median age was 30.6 years and eight (72.7%) were female. RESULTS: All patients had previous ulcerative colitis diagnosis and in five cases emergency colectomy was done by toxic megacolon. The mean time until of Crohn's disease diagnosis was 30.6 (6-80) months after ileal pouch-anal anastomosis. Ileostomy closure was possible in 10 cases except in one that had ileal pouch fistula, perianal disease and small bowel involvement. In the long-term follow-up, three patients had perineal fistulas and one had also a pouch-vaginal fistula. All of them were submitted to a new ileostomy and one had the pouch excised. Another patient presented pouch-vaginal fistula which was successfully treated by mucosal flap. Three patients had small bowel involvement and three others, pouch involvement. All improved with medical treatment. Presently, the mean follow-up is 76.5 months and all patients are in clinical remission, and four have fecal diversion. The remaining patients have good functional results with 6-10 bowel movements/day. CONCLUSION: Crohn's disease diagnosis after ileal pouch-anal anastomosis for ulcerative colitis may be usual and later complications such fistulas and stenosis are common. However, when left in situ ileal pouch is associated with good function.

Análise da estrutura de duas unidades fitofisionômicas de savana (cerrado) no sul do Brasil

The Jaguariaiva region is located at Parana State, southern Brazil, and it keeps up the last remnants of savanna vegetation in the State. Thus, it should be considered a mark of the meridional distribution limit of this vegetation type in Brazil. The Parque Estadual do Cerrado (24º09' S; 50º18' WG), whose vegetation is not solely composed by savanna forms, was the object of this study that analysed the vegetation of two dominant savanna physiognomic types (cerrado sensu stricto and campo cerrado). Twenty quadrats of 200m² (20 x 10m) were sistematicaly established in each physiognomic unit, and all the individuals having Basal Perimeter (BP) over 15 cm were sampled. The survey results indicated a low number of woody species in both units (33 species in cerrado sensu stricto and 18 in campo cerrrado). Most important species were virtually the same for both units, specially Byrsonima coccolobifolia, Acosinium subelegans, Couepia grandiflora and Stryphnodendron adstringens. The total density, total dominance and diversity were higher in cerrado sensu stricto. Moreover. there was apparently a higher lloristic resemblance with savannas of São Paulo State, specially those located in the South of thc State.

Isotopic view of vegetation and carbon and nitrogen cycles in a cerrado ecosystem, southeastern Brazil

Carbon and nitrogen biogeochemical cycles in savannas are strongly regulated by the seasonal distribution of precipitation and pulses of nutrients released during the wetting of the dry soil and are critical to the dynamics of microorganisms and vegetation. The objective of this study was to investigate the spatial and temporal variability of C and N isotope ratios as indicators of the cycling of these elements in a cerrado sensu stricto area, within a protected area in a State Park in the state of São Paulo, Brazil. The foliar δ13C and δ15N values varied from -33.6 to -24.4 ‰ and -2.5 to 4.5 ‰, respectively. The δ13C values showed a consistent relationship with canopy height, revealing the importance of structure of the canopy over the C isotopic signature of the vegetation. Carbon isotopic variations associated with the length of the dry season indicated the importance of recent fixed C to the integrated isotopic signature of the leaf organic C. The studied Cerrado species showed a depleted foliar δ15N, but a wide range of foliar Nitrogen with no difference among canopy heights. However, seasonal variability was observed, with foliar δ15N values being higher in the transition period between dry and rainy seasons. The variation of the foliar C and N isotope ratios presented here was consistent with highly diverse vegetation with high energy available but low availability of water and N.

The ichthyofauna of upper rio Capivari: defining conservation strategies based on the composition and distribution of fish species

Although the rio Capivari basin is recognized as an area of great importance for the ichthyofauna, it lacks virtually every basic requirement for the definition of appropriate conservation strategies, since not even its species composition is known. The objective of this work is to determine the composition and distribution of fish species in the upper rio Capivari basin, relating them to the local physical features, and to evaluate the effectiveness of proposed conservations units, delimited based on areas of native vegetation remains, on the conservation of local ichthyofauna. During 2007, 50 different watercourses were sampled with gillnets, cast nets and kick nets. A total of 1308 individuals belonging to 41 species were captured. Degree of conservation, altitude and width were the parameters that best explained fish species richness. Considering the recently proposed boundaries for potential conservation units in the region only 15 or 20 out of 41 species would be found in the State Park and Environmental Protection Area respectively. In practice, the proposed conservation units would not be effective tools for fish conservation, since it would be located in mountainous areas of high altitude, of headwaters streams and where few species are found. In such context, the conservation of specific stretches of larger rivers is critical.

Native bromeliads as biomonitors of airborne chemical elements in a Brazilian restinga forest

Epiphytic bromeliads have been used as biomonitors of air pollution since they have specialized structures in leaves for absorbing humidity and nutrients available in the atmosphere. Leaves of five bromeliad species were collected in the conservation unit Parque Estadual Ilha do Cardoso, Sao Paulo State, Brazil, and analyzed by INAA. Vriesea carinata was the species showing most accumulation, with the highest mass fractions of K, Na, Rb and Zn. Similar results were previously found for the same species collected in the dense ombrophilous forest. Chemical composition of bromeliads provided an indication of the atmosphere status in the conservation unit.

Status of chemical elements in Atlantic Forest tree species near an industrial complex

Environmental quality assessment studies have been conducted with tree species largely distributed in the Atlantic Forest. Leaf and soil samples were collected in the conservation unit Parque Estadual da Serra do Mar (PESM) nearby the industrial complex of Cubatao, Sao Paulo State, Brazil, and analyzed for chemical elements by instrumental neutron activation analysis. Results were compared to background values obtained in the Parque Estadual Carlos Botelho (PECB). The higher As, Fe, Hg and Zn mass fractions in the tree leaves of PESM indicated anthropogenic influence on this conservation unit.
