Fungos anamorfos do solo da região dos lagos no Município de Santa Gertrudes, SP, Brasil

O solo do pólo cerâmico no município de Santa Gertrudes, SP, tem sido poluído há décadas por diversos elementos químicos, principalmente chumbo e zinco. Foram realizadas quatro coletas de amostras de solo, duas durante a época chuvosa e duas na seca, em cinco locais, de novembro de 2002 a junho de 2003, determinando-se temperatura, pH, teores de chumbo e zinco e a umidade do solo. Os fungos foram isolados pelo método de Warcup, modificado pelo preparo de suspensões aquosas de solo (1:10) e aplicação de 1 cm³ das suspensões sobre malte agar (2%), adicionado de Zn(NO3)2 e Pb(NO3)2 em concentrações crescentes: 0, 100, 200, 500 e 1.000 mg dm-3. Após cinco dias de incubação a 25 ºC, as colônias foram purificadas e identificadas. Foram obtidos 70 táxons de fungos anamorfos, com 70% de similaridade entre as micotas obtidas nos meios com os dois metais. Foram isolados 43 táxons nos meios de cultura com Pb(NO3)2, com predominância deles nas concentrações mais elevadas (500 a 1.000 mg dm-3). Foram obtidos 63 táxons nos meios com Zn(NO3)2, principalmente nas concentrações moderada e elevada (200 e 500 mg dm-3). Prevaleceram espécies de Trichoderma, de Penicillium e diversos fungos que são encontrados associados a substratos vegetais em decomposição. A tendência de se obter número elevado de táxons em meios de cultura com concentrações moderadas a elevadas de Zn e Pb pode ser justificada pela existência de bem adaptada e competitiva micota do solo, caracterizada por elevada capacidade de tolerância aos metais e eficiente habilidade sapróbia competitiva.

Distribution of Cr, Ni, Cu, Cd and Pb in different molecular size of humic fractions extracted from water and sediment samples collected at Anhumas reservoir - Araraquara/SP

In this work was studied the distribution of Cr, Ni, Cu, Cd and Pb in humic fractions with different molecular size. The HS were extracted from waters (AHS), surface sediments (HESS), interface water sediment (HSIS) and bottom sediment (HSBS) collected in the Anhumas surface water collection reservoir, located in the district of Araraquara - São Paulo State Brazil. The humic substances were extracted by procedures recommended by International Humic Substances Society (IHSS). After purification by dialysis, the humic substances were fractionated using a multistage tangential flow ultrafiltration system. The fractionation patterns of HS characterized a mass distribution relatively uniform among the fractions with different molecular sizes, with larger values in the fractions F-2 (20.8%) and F-4 (23.8%), Except for the ions Pb(II) and Cu(II), which presented relatively higher concentrations in the fractions F-2 and F-4, respectively. In general, chromium, nickel, cadmium and lead have similar distributions in the five fractions with larger and medium molecular sizes (F-1 to F-5). With relation to the mass distributions in the different humic substances fractions extracted from sediment samples collected at three depth, they presented 42-48% of HS in the fractions with larger molecular sizes (F-1 and F-2), 29-31% in the middle fractions (F-3 and F-4) and 13-20% in the fractions with smaller molecular sizes (F-5 and F-6). In general, the metallic ions presented distributions similar among the respective fractions F-1 to F-6, Exceptions for Pb(II) and M(II) in surface sediment with concentrations relatively smaller in the fractions F-2 and F-4, respectively,

Pratylenchus jaehni sp n. from citrus in Brazil and its relationship with P-coffeae and P-loosi (Nematoda : Pratylenchidae)

A lesion nematode population infecting citrus in the state of São Paulo, Brazil is described and named Pratylenchus jaehni sp. n. Biological, molecular and morphological characteristics of this new species are compared with those of the morphologically similar P. coffeae and P. loosi. Results of mating experiments showed that R jaehni is reproductively isolated from P coffeae. Molecular (D2/D3 DNA sequences) dissimilarities among P. jaehni sp, n., P. coffeae and P. loosi were documented in a previous study. The morphology of seven R coffeae populations from tropical America and eastern Java and a P loosi population from Sri Lanka is used for comparison with the morphology of P. jaehni sp. n. Pratylenchus jaehni differs from R coffeae and P. loosi by only a few morphological ;characters of the females. The mean values of stylet length, stylet knob height, and vulva position are smaller (less than or equal to15 vs greater than or equal to15 mum, less than or equal to2.7 vs greater than or equal to2.7 mum, less than or equal to79 vs greater than or equal to79%) than those in P coffeae and P loosi. The tail terminus is usually subhemispherical and smooth in P jaehni sp. n.. whereas it is commonly truncate and indented in most P. coffeae populations and bluntly or finely pointed in P. loosi. Because of the morphological similarities among P. jaehni sp. n., P. coffeae and P. loosi, examination of at least ten specimens is required to obtain a reliable diagnosis based on morphology. Nineteen morphometric parameters for P. jaehni sp. n. and P. coffeae ranged from 0-13% smaller in fixed than in live specimens.

The first report of Hepatozoon sp (Apicomplexa : Hepatozoidae) in neotropical felids from Brazil

In order to investigate the occurrence of Hepatozoon infection in Neotropical felids from Brazil, blood from the jugular or cephalic vein was taken from 29 non-domestic felids including ocelot (Leopardus pardalis), little spotted cat (Leopardus tigrinus), margay (Leopardus wiedii), and jaguarondi (Puma yagouaroundi) from the Northeast region of Brazil. Hepatozoon infection was confirmed by light microscopy and molecular techniques. The results showed five naturally infected felids. Partial sequences of the 18S rRNA gene of the Hepatozoon sp. from these felids were further analyzed. Sequences revealed that the isolates found are closely related to Hepatozoon sp. from domestic cats in Spain. Hepatozoon species from Neotropical felids were identified molecularly and characterized for the first time. This is also the first report of Hepatozoon infection in a little spotted cat.

Capacidade de carga real (ccr) da caverna de santana, parque estadual turístico do alto ribeira (Petar) - sp, e indicações para o seu manejo turístico

The tourist use of Santana cave provides a row of environmental damages, compromising partially the pristine conditions. Among the measures adopted to avoid this situation, this issue presents a contribution for the physical limits to tourist visitation and the indications for speleotouristic management. It was used the Cifuentes Carrying Capacity method and some basic principles of Visitors Impact Management Framework - VIM. The results show a Real Carrying Capacity (CCR) about 120 visits daily on the cave. The discussions raise a few hypotheses about the alteration in the method used and the temporal frequency between visitors groups, suggesting a provisional CCR of 117 and 135 visitors daily, respectively, during the week and in the weekends and holidays. The conclusions appoint the necessity of a conceptual revision in the Carrying Capacity methods, mainly about its adaptation for tourist management in caves. In the case studied, it is suggested the immediate beginning of environmental monitoring of the cave, to verify the plausibility from proposed visitation limits and the possible contributions for to mitigate the environmental impacts from speleotourism.
