Reprodu??o de peixes (Osteichthyes) em afluentes do reservatório de Volta Grande, Rio Grande, Sudeste do Brasil
Braga, Francisco Manoel de Souza;
Iheringia. Série Zoologia , 2001, DOI: 10.1590/S0073-47212001000200009
Abstract: the most abundant species caught in the tributaries of the volta grande dam, buriti, divisa and água comprida streams were plagioscion squamosissimus (heckel, 1840), pimelodus maculatus lacépède 1803, myleus tiete (eigenmann & norris, 1900), astyanax bimaculatus (linnaeus, 1758) and a. fasciatus (cuvier, 1819). plagioscion squamosissimus and pimelodus maculatus do not have reproduction activity in the area, they just use the creeks to food and growth. myleus tiete and astyanax bimaculatus use the area to reproduction whereas a. fasciatus uses it to reproduction, food and growth.
Estudo da diversidade de Sardinella brasiliensis (Steindachner, 1879), na área entre Macaé (22o23'S) e Ilha de Santa Catarina (27o35'S): 1. Crescimento de dimens?es corporais
Braga, Francisco Manoel de Souza;
Revista Brasileira de Zoologia , 1987, DOI: 10.1590/S0101-81751987000300006
Abstract: the growth of body proportions of sardinella brasiliensis was not homogeneous in the study area, between macaé (rj) and santa catarina island (sc); the growth rates (k) of the von bertalanffy growth curve were greater than growth rates for another áreas. in this area the biomass estimates for pelagic fish is poor, and near cabo frio occurs an upwelling zone. these facts permit the sardines to attain large lengths in this area. between rio de janeiro and florianópolis the growth rates were lower than in the northern part and paranaguá bay. on the other hand the biomass estimates for pelagic fish in rio de janeiro-florianópolis region was very high, and in this zone the population density is high and the growth rates are small. paranaguá bay is a particular region because of its geographical and oceanographic conditons; this is a shelter region with different features and the sardines living there attain small length. in this area the growth rates are intermediary among growth rates for fishes from macaé-cabo frio and rio de janeiro-florianópolis regions. therefore, the growth rates for sardines in southeast brazilian proves to be dependent of the population density, food and oceanographic conditions.

Abstract: Neste trabalho s o descritos aspectos da biologia da reprodu o em Characidium lauroi e C. alipioi. A matura o das g nadas é dividida em quatro estádios e s o descritos no ciclo anual. Em Characidium lauroi, existe um maior período reprodutivo na primavera e, em C. alipioi o maior período reprodutivo é no ver o. O tamanho da primeira matura o gonadal foi ao redor de 4,2 cm de comprimento total para machos e de 5,1 cm para fêmeas de Characidium lauroi, para machos de C. alipioi, foi ao redor de 6,2 cm de comprimento total e, para fêmeas, foi de 5,8 cm. Os valores da rela o gonadossomática indicam o estádio de maturidade e foram determinados para cada espécie e sexo. Os altos valores vistos em outubro para machos e fêmeas de Characidium lauroi marcam os picos de matura o em ambos os sexos, e os picos coincidem com o período reprodutivo. Para Characidium alipioi, os picos foram em fevereiro e também coincidem com o período reprodutivo. Aspects of the reproductive biology of Characidium lauroi and C. alipioi were described. Maturation of the gonads was divided into four stages, and the distribution of the stages in an annual cycle was reported. The Characidium lauroi has a higher spawning period in the spring, and the C. alipioi, in the summer. The size at sexualmaturity of the Characidium lauroi was about 4.2 cm total length for males and 5.1 cm for females; as for the C. alipioi, males were about 6.2 cm total length and females were about 5.8 cm. The gonadosomatic index values indicated the stage of maturity and were determined for each species and sex. The high values observed in October for Characidium lauroi males and females mark the maturation peaks in both sexes, and the peaks coincided with the spawning period. As for C. alipioi, the peaks were in February and also coincided with the spawning period.

Abstract: hantavirus disease is caused by the hantavirus, which is an rna virus belonging to the family bunyaviridae. hantavirus disease is an anthropozoonotic infection transmitted through the inhalation of aerosols from the excreta of hantavirus-infected rodents. in the county of itacoatiara in the state of amazonas (am), brazil, the first human cases of hantavirus pulmonary and cardiovascular syndrome were described in july 2004. these first cases were followed by two fatal cases, one in the municipality of maués in 2005 and another in itacoatiara in 2007. in this study, we investigated the antibody levels to hantavirus in a population of 1,731 individuals from four different counties of am. sera were tested by igg/igm- enzyme-linked immune-sorbent assay using a recombinant nucleocapsid protein of the araraquara hantavirus as an antigen. ten sera were igg positive to hantavirus (0.6%). among the positive sera, 0.8% (1/122), 0.4% (1/256), 0.2% (1/556) and 0.9% (7/797) were from atalaia do norte, careiro castanho, itacoatiara and lábrea, respectively. none of the sera in this survey were igm-positive. because these counties are distributed in different areas of am, we can assume that infected individuals are found throughout the entire state, which suggests that hantavirus disease could be a local emerging health problem.

Abstract: Background Dengue is a vector-borne disease in the tropical and subtropical region of the world and is transmitted by the mosquito Aedes aegypti. In the state of Amazonas, Brazil during the 2011 outbreak of dengue all the four Dengue virus (DENV) serotypes circulating simultaneously were observed. The aim of the study was to describe the clinical epidemiology of dengue in Manaus, the capital city of the state of the Amazonas, where all the four DENV serotypes were co-circulating simultaneously. Methodology Patients with acute febrile illness during the 2011 outbreak of dengue, enrolled at the Funda??o de Medicina Tropical Dr. Heitor Viera Dourado (FMT-HVD), a referral centre for tropical and infectious diseases in Manaus, were invited to participate in a clinical and virological descriptive study. Sera from 677 patients were analyzed by RT-nested-PCRs for flaviviruses (DENV 1–4, Saint Louis encephalitis virus-SLEV, Bussuquara virus-BSQV and Ilheus virus-ILHV), alphavirus (Mayaro virus-MAYV) and orthobunyavirus (Oropouche virus-OROV). Principal Findings Only dengue viruses were detected in 260 patients (38.4%). Thirteen patients were co-infected with more than one DENV serotype and six (46.1%) of them had a more severe clinical presentation of the disease. Nucleotide sequencing showed that DENV-1 belonged to genotype V, DENV-2 to the Asian/American genotype, DENV-3 to genotype III and DENV-4 to genotype II. Conclusions Co-infection with more than one DENV serotype was observed. This finding should be warning signs to health authorities in situations of the large dispersal of serotypes that are occurring in the world.

Abstract: we trace the origins and development of the annual meeting of the rain prophets, held in quixadá, ceará, demonstrating how the invention of this tradition depends on the circulation of public, academic and media discourses in order to achieve the goal of preserving the culture imagined to exist in the rural northeast. we examine the intersection between culture and folklore, analizing the collaboration of individuals, media and researchers (including anthropologists) in the production of culture related to rain prediction. we show how texts produced by the media and researchers enter into public discourse about the rain prophets. in these ways, we are simultaneously inventing and preserving a tradition. taking a close look at the intertextuality of media, academic and public discourses about the rain prophets, we contribute to debates about the influence our work has on the knowledge and practices we study.

Abstract: South Mato Grosso has been developing very rapidly in recent decades, and it is clearly leaving behind the status of being solely an agricultural region to become an important state in the areas of commerce and industry. Nevertheless, it is still possible to observe the harmful effects of atmospheric pollution due to biomass burning activities, even if those actions are being systematically reduced in the state throughout the past several years. This kind of pollution persists not only due to local activities but also due to the pollution of other states and even other border countries. Satellite remote sensing has proven to be an important tool of environmental control vis-à-vis the ease of data acquisition, accuracy and wide temporal range. A study has been conducted of spatial and temporal concentration of carbon monoxide (CO) in the state of South Mato Grosso from 2001 through 2012 using the MOPITT sensor onboard the TERRA satellite. The carbon monoxide comes principally from the incomplete combustion of vehicles engines and biomass burnings. A direct correlation of the CO concentration in the state of South Mato Grosso is observed precisely during the months of drought (August to October), for which the number of fire outbreaks is the highest of the year.
