Os roteiros de turismo no espaço rural vêm crescendo significativamente no Brasil nos últimos 10 anos. Apreender a gênese e o desenvolvimento de alguns roteiros turísticos no estado do Paraná vem sendo uma de nossas preocupações como geógrafos. Nesse sentido, esse texto discute o surgimento do Roteiro de Turismo Rural “Doce Iguassu”, considerando os estabelecimentos, a gestão de Roteiro e as principais ações realizadas. Através de trabalhos de campo e entrevistas com os gestores do Roteiro e com proprietários de estabelecimentos, procuramos verificar como surgiu esse roteiro turístico, quais as instituições e atores envolvidos, e quais as principais ações realizadas. Pelo fato do turismo rural ser embrionário no município, o Roteiro pesquisado foi de suma importância para a territorialização do turismo em Capanema. Por sua vez, Capanema apresenta potencial turístico, em virtude do Rio Iguaçu e do limite com o Parque Nacional do Iguaçu. Utilizando a metodologia de nossa tese de doutorado (CANDIOTTO, 2007), procuramos apreender o processo de territorialização do turismo em Capanema.

Este trabalho coloca em pauta os processos de reinserção das sociedades indígenas brasileiras nos contextos intra e extrarregional objetivando analisar a realidade vivenciada pelas sociedades indígenas (e núcleos quilombolas) do vale do Rio Doce e entorno (estado de Minas Gerais), realizando em paralelo, uma retrospectiva geohistórica da trajetória dos remanescentes de povos indígenas do Tronco Macro-Jê hoje sediados no sudeste do Brasil como os Krenak e Pataxó. A metodologia utilizada compreendeu: pesquisa bibliográfica/ cartográfica/ documental; reconhecimentos de campo; diagnóstico da situação histórica e atual das comunidades indígenas (e quilombolas) na região; organização dos dados em matrizes; contextualização e sistematização das informações. A interpretação dos processos abordados permitiu a associação da experiência vivida por estes atores com “paisagens culturais alternativas/ excluídas”, de acordo com concepções em curso da Etnogeografia/ Geografia Política imbricadas com o Marxismo Cultural.

A Phyla betulifolia (Kunth) Greene, conhecida popularmente como capim-doce, é uma erva perene pertencente à família botânica Verbenaceae. Na medicina popular, é utilizada em tratamentos de resfriados, bronquite, tosse e também como relaxante muscular. A micropropagação é uma das técnicas mais utilizadas em plantas medicinais, pelo fato de oferecer vantagens de manutenção de genótipos e fenótipos de híbridos, mutações genéticas selecionadas e excelentes estados fitossanitários das plantas obtidas. Dessa forma, o objetivo deste estudo foi avaliar os efeitos das diferentes concentrações do meio de cultura MS (MURASHIGE; SKOOG, 1962) na micropropagação da phyla betulifolia. O trabalho foi realizado no Laboratório de Recursos Genéticos e Biotecnologia Vegetal, da Embrapa Amazônia Oriental. O experimento foi realizado em delineamento casualizado contendo três concentrações de meio de cultura: MS, MS 1/2 e MS 1/4. Cada concentração de meio apresentava sete repetições com dois frascos, e cada frasco apresentava três explantes. As variáveis avaliadas foram número de raízes, número de brotações, comprimento da maior raiz e comprimento do maior broto, e para análise estatística das variáveis utilizou-se o programa Sisvar. Ocorreu diferença estatística significativa para todas as variáveis avaliadas. O meio MS apresentou os maiores valores significativo, respectivamente, 10,20; 2,60; 2,41 cm e 2,86 cm para número de raiz e de broto e para comprimento de raiz e de broto. Os menores valores foram registrados no meio de cultura MS com ¼ da sua concentração. O meio de cultura MS induz formação de plântulas com os maiores valores significativo para todas as variáveis avaliadas.

Shelled, roasted and salted cashew nut kernels were packaged in three different flexible materials (PP/PE= polypropylene / polyethylene; PETmet/PE= metallized polyethylene terephthalate / polyethylene; PET/Al/LDPE= polyethylene terephthalate / aluminum foil / low density polyethylene ), with different barrier properties. Kernels were stored for one year at 30° C and 80% relative humidity. Quantitative descriptive sensory analysis (QDA) were performed at the end of storage time. Descriptive terms obtained for kernels characterization were brown color, color uniformity and rugosity for appearance; toasted kernel, sweet, old and rancidity for odor; toasted kernel, sweet, old rancidity, salt and bitter for taste, crispness for texture. QDA showed that factors responsible for sensory quality decrease, after one year storage, were increase in old aroma and taste, increase in rancidity aroma and taste, decrease in roasted kernel aroma and taste, and decrease of crispness. Sensory quality decrease was higher in kernels packaged in PP/PE.

The fermented cassava starch has been used as raw material for many products of the Brazilian culinary mainly in the biscuit manufacturing. Starch of arrowroot, english potato, baroa-potato and cassava were extracted and fermented in order to investigate other fermented starch sources for manufacturing biscuits. The fermented starch showed characteristics similar to those of commercial fermented cassava starch. The biscuits manufactured from the fermented starch of english potato didn?t expand and was very hard and the biscuits manufactured from the fermented starch of arrowroot and of baroa-potato were approved by the consumers and can be used in the biscuit manufacturing the same way as the fermented cassava starch.

Flavobacterium columnare is the causative agent of columnaris disease in freshwater fish, implicated in skin and gill disease, often causing high mortality. The aim of this study was the isolation and characterization of Flavobacterium columnare in tropical fish in Brazil. Piracanjuba (Brycon orbignyanus), pacu (Piaractus mesopotamicus), tambaqui (Colossoma macropomum) and cascudo (Hypostomus plecostomus) were examined for external lesions showing signs of colunmaris disease such as greyish white spots, especially on the head, dorsal part and caudal fin of the fish. The sampling comprised 50 samples representing four different fish species selected for study. Samples for culture were obtained by skin and kidney scrapes with a sterile cotton swabs of columnaris disease fish and streaked onto Carlson and Pacha (1968) artificial culture medium (broth and solid) which were used for isolation. The strains in the liquid medium were Gram negative, long, filamentous, exhibited flexing movements (gliding motility), contained a large number of long slender bacteria and gathered into ‘columns'. Strains on the agar produced yellow-pale colonies, rather small, flat that had rhizoid edges. A total of four Flavobacterium columnare were isolated: 01 Brycon orbignyanus strain, 01 Piaractus mesopotamicus strain, 01 Colossoma macropomum strain, and 01 Hypostomus plecostomus strain. Biochemical characterization, with its absorption of Congo red dye, production of flexirubin-type pigments, H2S production and reduction of nitrates proved that the isolate could be classified as Flavobacterium columnare.

The "surubim do Paraíba" (Steindachneridion parahybae) is a freshwater catfish endemic to the Paraíba do Sul River basin, Brazil. This species has been seriously threatened by environmental disturbances in the last several decades. Wild Steindachneridion parahybae males and females were collected in 2003 and taken to the hatchery of a power plant of the Companhia Energética de São Paulo (CESP). Steindachneridion parahybae broodstocks were artificially induced to reproduce in December 2003 using a combination of carp pituitary extract (CPE) and human chorionic gonadotropin (hCG). Oocytes and milt were stripped; the fertilized eggs were transferred to 60-liter conical incubators and hatched larvae distributed in nine horizontal trays. Exogenous feed was started just after yolk sac absorption. A high rate of cannibalism and photophobia were observed during the larval period, resulting in a 26% survival rate from larvae to fingerlings.

A new species of the relatively poorly known Neotropical freshwater stingray genus Plesiotrygon Rosa, Castello & Thorson, 1987 is described from the main channel and smaller tributaries (Ríos Itaya and Pachitea) of the upper Amazon basin in Peru. The first specimen to be collected, however, was from much farther east in Rio Solimões in 1996, just down-river from Rio Purus (specimen unavailable for this study). Plesiotrygon nana sp. nov., is a very distinctive and unusually small species of freshwater stingray (Potamotrygonidae), described here mostly from three specimens representing different size classes and stages of sexual maturity. Plesiotrygon nana sp. nov., is distinguished from its only congener, P. iwamae Rosa, Castello & Thorson, 1987, by numerous unique features, including: dorsal coloration composed of very fine rosettes or a combination of spots and irregular ocelli; very circular disc and snout; very small and less rhomboidal spiracles; short snout and anterior disc region; narrow mouth and nostrils; denticles on dorsal tail small, scattered, not forming row of enlarged spines; adult and preadult specimens with significantly fewer tooth rows; fewer caudal vertebrae; higher total pectoral radials; very small size, probably not surpassing 250 mm disc length or width, males maturing sexually at around 180 mm disc length and 175 mm disc width; distal coloration of tail posterior to caudal stings usually dark purplish-brown; and features of the ventral lateral-line canals (hyomandibular canal very narrow, infraorbital and supraorbital canals not undulated, supraorbital and infraorbital loops small and narrow, supraorbital loop very short, not extending posteriorly to level of mouth, jugular and posterior infraorbital canals short, not extending caudally to first gill slits, subpleural loop very narrow posteriorly; absence of anterior and posterior subpleural tubules). To provide a foundation for the description of P. nana sp. nov., morphological variation in P. iwamae was examined based on all type specimens as well as newly collected and previously unreported material. Two specimens topotypic with the male paratype of P. nana sp. nov., referred to here as Plesiotrygon cf. iwamae, are also reported. Relationships of the new species to P. iwamae are discussed; further characters indicative of Plesiotrygon monophyly are proposed, but the genus may still not be valid. Plesiotrygon nana sp. nov., is commercialized with some regularity in the international aquarium trade from Iquitos (Peru), an alarming circumstance because nothing is known of its biology or conservation requirements.
