Inventário da ictiofauna do alto rio Paraíba do Sul e caracterização molecular das espécies encontradas

The state of São Paulo has four main drainages: Paraná river, Paraíba do Sul river, Ribeira do Iguape river and coastal rivers. The Paraíba do Sul river is born in Sao Paulo and drains an important range of land east of the state. Its ichthyofauna has some similarities and many differences from the continental and coastal drainages which highlights the importance of this study. Surveys conducted in the ichthyofauna of this basin, as in other large river basins in Brazil, is still incomplete. Moreover, there is no consensus about the taxonomic status of many species listed in these surveys. Considering the promising use of DNA barcode as a global system for species identification, the present study is aimed to establishing an inventory of the ichthyofauna of the São Paulo portion of the river Paraíba do Sul and simultaneously build a DNA barcode reference sequence library for fish found. Were obtained and analyzed 354 sequences of the gene cytochrome oxidase c subunit I (COI) belonging to 66 species of São Paulo portion of the Paraíba do Sul river. The average K2P distance between individuals within species of this basin was 0.48%, and 9,87% between species within a genus. Five pairs of species (10 species) showed low levels of interspecific genetic divergence (<2%),but all could be correctly identified. This study showed that the fish species analyzed could be identified efficiently through the use of barcode generating data that can provide information for further studies of this fauna, besides contributing to the global initiative to characterize the species of fish in the world of a molecular point of view.

Memória ambiental, cultural e turismo no vale histórico do Rio Paraíba do Sul: design de uma pesquisa

This text is aimed at disseminating cultural and environmental wealth of a region little known of major tour operators - which is strongly marked by historical traditions, in a bucolic rural still and by the hospitality of its residents. The Historic Valley of Rio Paraíba do Sul, although located in the Rio - Sao Paulo road lives in the shadow of the remarkable progress of the industrial cities in the main Valley. This paper presents results of research that deepened the knowledge of this region, with notable findings from the standpoint of culture and tourism, regional and national history. Isolated by considerable geographical barriers, this region has two aspects: the rebirth of nature after the decline of coffee plantations, with ecological sanctuaries that can now point toward environmental sustainability, and the formation of a culture with two historical times - refinement inherited from the barons coffee, paradoxically linked to the rustic countryside and modernity derived of its proximity to major centers. The results presented here are part of exploratory research, but were presented at different events, emphasizing the baroque character of practices derived from these two historical times and tourist potential related to the “cultura tropeira” and to hospitality that marks this countryside.

Study on coinfecting vector-borne pathogens in dogs and ticks in Rio Grande do Norte, Brazil

Since dogs presenting several vector borne diseases can show none or nonspecific clinical signs depending on the phase of infection, the assessment of the particular agents involved is mandatory. The present study aimed to investigate the presence of Babesia spp., Ehrlichia spp., Anaplasma spp., Hepatozoon spp. and Leishmania spp. in blood samples and ticks, collected from two dogs from Rio Grande do Norte showing suggestive tick-borne disease by using molecular techniques. DNA of E. canis, H. canis and L. infantum were detected in blood samples and R. sanguineus ticks collected from dogs. Among all samples analyzed, two showed the presence of multiple infections with E. canis, H. canis and L. infantum chagasi. Here we highlighted the need for molecular differential diagnosis in dogs showing nonspecific clinical signs.

Molecular confirmation of ovine herpesvirus 2-induced malignant catarrhal fever lesions in cattle from Rio Grande do Norte, Brazil

Molecular findings that confirmed the participation of ovine herpesvirus 2 (OVH-2) in the lesions that were consistent with those observed in malignant catarrhal fever of cattle are described. Three mixed-breed cattle from Rio Grande do Norte state demonstrated clinical manifestations that included mucopurulent nasal discharge, corneal opacity and motor incoordination. Routine necropsy examination demonstrated ulcerations and hemorrhage of the oral cavity, corneal opacity, and lymph node enlargement. Significant histopathological findings included widespread necrotizing vasculitis, non-suppurative meningoencephalitis, lymphocytic interstitial nephritis and hepatitis, and thrombosis. PCR assay performed on DNA extracted from kidney and mesenteric lymph node of one animal amplified a product of 423 base pairs corresponding to a target sequence within the ovine herpesvirus 2 (OVH-2) tegument protein gene. Direct sequencing of the PCR products, from extracted DNA of the kidney and mesenteric lymph node of one cow, amplified the partial nucleotide sequences (423 base pairs) of OVH-2 tegument protein gene. Blast analysis confirmed that these sequences have 98-100% identity with similar OVH-2 sequences deposited in GenBank. Phylogenetic analyses, based on the deduced amino acid sequences, demonstrated that the strain of OVH-2 circulating in ruminants from the Brazilian states of Rio Grande do Norte and Minas Gerais are similar to that identified in other geographical locations. These findings confirmed the active participation of OVH-2 in the classical manifestations of sheep associated malignant catarrhal fever.

Turismo imobiliário: uma reflexão sobre o impacto da crise financeira de 2008 e perspectivas no Rio Grande do Norte

Evaluación participativa de los impactos sociales del turismo residencial y meta-análisis de resultados: un caso de estudio en Pipa (Rio Grande do Norte, Brasil)

Este artículo presenta una propuesta metodológica para la evaluación participativa de impactos sociales. Se ejemplifica mediante la descripción del proceso y resultados de una investigación realizada en la comunidad turística de Pipa (Rio Grande do Norte, Brasil) en la que se desarrolló un proceso de participación orientado a discutir el modelo de turismo residencial implantado en este territorio mediante el identificación y evaluación de sus impactos sociales. La novedad de esta propuesta reside en que se añade, a los beneficios y utilidades de la evaluación participativa de impactos sociales, un meta-análisis realizado sobre los resultados del proceso de participación. Este meta-análisis hace uso de las herramientas informáticas propias del Análisis de Redes Sociales aplicadas al estudio de los mapas causa-efecto elaborados por los participantes. Los resultados de este análisis cuantitativo se completan e interpretan con la información obtenida a través de entrevistas en profundidad y revisión documental, permitiendo: 1) identificar las causas últimas de los impactos sociales derivados del turismo residencial a escala local y 2) una mejor comprensión de la complejidad causal de estos impactos. El meta-análisis ha identificado que la primacía de los intereses de las empresas inmobiliarias internacionales sobre el interés general local se sustenta sobre su capacidad ilusoria de controlar la demanda mediante agresivas campañas de marketing. Esta información permite la deconstrucción del discurso desarrollista del turismo y posibilita la demarcación de nuevas áreas de acción estratégica orientadas a la maximización del beneficio colectivo.
