Hassalstrongylus luquei n. sp. is described from the small intestine of Euryoryzomys russatus (Rodentia: Sigmodontinae) collected in the Atlantic Forest (Rio de Janeiro State, Angra dos Reis, Brazil). The genus Hassalstrongylus includes 16 Neotropical species. The main characters of new species are subsymmetrical caudal bursa with a type 2-2-1, rays 8 branching at midlength of dorsal trunk, right lateral trunk larger than the left and the longest spicules in the genus. Only three species of Hassalstrongylus have the rays 8 not emerging at the base trunk, these are: H. mazzai; H. aduncus; and H. echalieri. However, the present species is distinguished from H. mazzai by having the dorsal rays divided at fourth part of the trunk, H. bocqueti by having rays 5 bifurcating at third part of trunk and H. echalieri by having a pattern of 2-2-1.

La historia del Palacio Quitandinha merece ser contada, aunque sea, brevemente: Joaquín Rolla, un empresario brasilero propietario de varios casinos, se había propuesto construir en un sector de la antigua hacienda Quitandinha, en Petrópolis, el que sería el casino-hotel más grande de América del Sur. En 1939, adquirió el terreno y en 1941 encargó la construcción de su ambicioso proyecto a los arquitectos Luis Fossati y Alfredo Baeta Neves. Eledificio se inauguró en 1944.

Este artículo propone un marco conceptual para el turismo comunitario en las favelas de la Zona Sur de Río de Janeiro, el cual beneficia a estas comunidades. Se explica cómo los guías locales utilizan el turismo como una herramienta para combatir la prevalente percepción negativa de las favelas y cómo ellos intentan rehumanizar la favela al brindar una narrativa cultural alternativa que cuestiona los estereotipos existentes, haciendo de estas visitas una forma de resistencia cotidiana. El artículo cubre el impacto material de estas visitas al resaltar las percepciones de los turistas antes y después de visitar una favela e incluye la opinión de residentes locales de una favela acerca de estas visitas.

Rio de Janeiro was elected in 2013 as the “Smart City of the Year” by the Smart City Expo World Congress, a fair held in Barcelona. The capital of the state of Rio de Janeiro was highlighted with the project Gestão de Alto Desempenho (High Performance Management) which includes the subproject Centro de Operações Rio (COR – Rio Operations Center). COR is a monitoring center that has 1,500 video cameras and analyzes data received in real time from several technological sensors scattered throughout the city. This is the result of an agreement between the city hall and several technology companies. The initiative is supported as part of the belief in a model of “polisdigitocracy”, a word that, according to former Mayor Eduardo Paes, means the digital version of Greek democracy for cities in the 21st century. This article is based on an ongoing investigation. It intends to evalua...

Dengue is one of the most prominent tropical epidemic diseases present in the Rio de Janeiro city and Southeast part of Brazil, due to the widespread conditions of occurrence of the dengue vector, the mosquito Aedesaegypti, such as high-temperature days interlaced with afternoon or nocturnal rainstorms in summer. This work has the objective of investigating the relationships between variabilities of the El Niño-South Oscillation (ENSO) and greater epidemics of dengue in Rio de Janeiro city. To accomplish this goal, the analysis and signal decomposition by cross-wavelet transform (WT) was applied to obtain the cross variability associated with variations of power and phase of both signals by characteristic periods and along with the time series. Data considered in the analysis are (the decimal logarithm of normalized value) of the monthly available notifications of dengue worsening, prov...

Interface areas between urban and sylvatic environments increase the contact between humans and wild animals, and may favour the transmission of zoonoses. The aim of this study was to describe the helminth fauna of a small mammal community in an urban-sylvatic interface area of the Brazilian Atlantic Forest. Twenty helminth species were recovered in six species of small mammals. Parasite sharing was observed in two helminth species among the marsupials. This study is the first report of a helminth infection for the marsupial Monodelphis americana (Müller, 1776). This is the first report of the nematodes Aspidodera raillieti Travassos, 1913, Viannaia hamata Travassos, 1914 and Trichuris sp. parasitizing the marsupial Marmosa paraguayana (Tate, 1931). None of the helminth species found has been reported to infect humans.

La presente investigación aborda las dinámicas de configuración y reconfiguración de identidades individuales y colectivas de los andinos en Río de Janeiro. El análisis parte de entender el desarraigo territorial, cultural y el proceso de adaptación sociocultural generado por el fenómeno migratorio. Se propone pensar en la migración como un derecho a buscar otras formas de vida enfrentando una lucha simbólica a través de diferentes modos de pertenencia.

Thunnus atlanticus is of great commercial importance in Brazil, but infections caused by helminth parasites can reduce its commercial value. In this paper, 15 species of Digenea and three of Monogenoidea were recovered from 61 specimens of T. atlanticus collected from the coastal zone of the State of Rio de Janeiro. Species of the family Didymozoidae were the dominant species, with highest prevalence and abundance values. The parasites showed the typical aggregated distribution pattern, except for Nasicola brasiliensis, which had an aleatory distribution pattern. Prevalence and abundance of Didymosulcus philobranchiarca, Didymocystis lamotheargumedoi and Didymosulcus wedli and prevalence of Koellikerioides internogastricus were positively correlated with the total length of the host. The abundance of Coeliotrema thynni was negatively correlated with total length of the host. New hosts re...

Wild birds are hosts of a variety of parasites. Their migratory behavior increases the dispersion of parasites and consequently the occurrence of diseases in various locations around the world. To identify the parasitological fauna of wild birds in the Tinguá Biological Reserve in Rio de Janeiro state-Brazil, 43 birds belonging to the orders Passeriformes and Columbiformes were captured and stool samples collected. Four birds (9.3%) were positive for parasites. In the fecal samples, trematode eggs of the Tanaisia sp and oocysts of coccidia as Isospora sp were found. The low parasite prevalence in wild birds found in this study may be an environmental quality indicator,because the reserve is a preserved area that has little human interference. We emphasize also thatthe use of the technique of collecting stool samples with anal swabs was successful for diagnostic purposes.

La segregación residencial en el espacio es una característica llamativa en la ciudad de Río de Janeiro. Áreas que presentan similitudes en cuanto a la asignación de bienes de consumo colectivos presentan ocupación por grupos sociales completamente diferentes. En este trabajo comparamos la distribución de servicios y equipos para uso colectivo con la distribución de ingresos y actividades, buscando caracterizar la demanda por la ubicación en el espacio. Así, podemos verificar las zonas eminentemente industriales, de servicios y residenciales, relacionándolas con la población y tipología de los habitantes, así como una idea aproximada de la ocupación de intersticios urbanos (por ejemplo, barrios marginales, ocupaciones clandestinas). Se pudo comprobar que la composición social y la distribución de los equipos no son por sí solas suficientes para establecer patrones de se...

This study evaluated the pollutant levels (NO2, SO2, CO, and O3), air quality index (AQI) and the influence of meteorological variables and coronavirus disease (COVID-19) pandemic on the air quality in Rio de Janeiro. The data set used comprises periods before (March-April, 2019) and during pandemic (March-April, 2020). According to the AQI results, on most days, the air quality was ranked as “good”. Brazilian air quality standards for SO2, O3, and NO2 were not exceeded in any of the monitoring stations during partial lockdown, while CO exceeded in all periods in one site due to industrial emission. Comparing both periods, descriptive statistics for the meteorological parameters presented no differences, which suggests similar conditions. However, when evaluated week by week in 2020, weather conditions presented some differences that probably affected pollutant concentrations. The co...

From October 2006 to March 2008, sixty specimens of Paralichthys isosceles, were captured in the littoral of the State of Rio de Janeiro Brazil. The present study deals with the taxonomic identification of the cestodes parasitizing this fish species, as well with the analysis of parasitological indexes, sites of infection, taking into account the hygienic-sanitary importance of the host in Brazilian and foreign markets. Fifty-six (93.3%) out of the collected fishes were infected with at least one specimen of metacestodes. Diphyllobothriidea were represented by plerocercoids of two species: Diphyllobothrium sp. 1 (similar to D. latum) in stomach, stomach mucosa and mesentery and Diphyllobothrium sp. 2 (similar to D. dendriticum) in intestine, liver, ovary and abdominal cavity. Trypanorhyncha, were represented by Grillotia carvajalregorum, in stomach, intestine, liver, mesentery, abdominal...
