Item Acesso aberto (Open Access) Dieta de Micoureus demerarae (Thomas) (Mammalia, Didelphidae) associada às florestas contíguas de mangue e terra firme em Bragança, Pará, Brasil(2006-12) FERNANDES, Marcus Emanuel Barroncas; ANDRADE, Fernanda Atanaena Gonçalves de; SILVA JÚNIOR, José de Sousa eThe diet of Micoureus demerarae (Thomas, 1905) was studied in mangrove and terra firme stands by using stomachal and faecal samples. The number of captured individuals was inversely proportional to availability of fruits and insects, being Coleoptera and Hemiptera the most consumed arthropod orders and Passifloraceae and Arecaceae the most ingested fruits. Thus, either fruits variability or their high yield during the dry season seem to explain the increase of captured animals in the terra firme stands, where they originally come from. The food items suggest that this species has an omnivorous diet, independently of the seasonality or distribution of available resources.Item Acesso aberto (Open Access) Parâmetros demográficos de Micoureus demerarae (Didelphidae, Marsupialia) em áreas contíguas de manguezal e terra firme, Bragança, Pará, Brasil(2007-06) ANDRADE, Fernanda Atanaena Gonçalves de; FERNANDES, Marcus Emanuel Barroncas; BRITO, Stélio Ângelo da CostaThis study investigated some aspects of the population dynamics of Micoureus demerarae (Thomas, 1905), such as: density, recruitment, and survivorship in two contiguous ecosystems, mangal and terra firme at the Fazenda das Salinas in the northeast of the state of Pará. One transect in each system was used for fieldwork. Data collection was carried out from November 2002 to September 2003. The following population parameters were estimated: density, recruitment, and survivorship. The results defined an open population with an even distribution for individuals from mangal and a clumped one for individuals from terra firme, and the evident seasonality with higher proportion of males in the terra firme. The reproductive period was the most important parameter to the population fluctuation in the beginning of the dry season. The environmental impacts over the population dynamics parameters of M. demerarae seem to be determinant for the maintenance of these populations.Item Acesso aberto (Open Access) Virological and serological diagnosis of rabies in bats from an urban area in the brazilian Amazon(Universidade Federal do Pará, 2015-12) OLIVEIRA, Rubens Souza de; COSTA, Lanna Jamile Corrêa da; ANDRADE, Fernanda Atanaena Gonçalves de; UIEDA, Wilson; MARTORELLI, Luzia Fatima Alves; KATAOKA, Ana Paula de Arruda Geraldes; ROSA, Elizabeth Salbé Travassos da; VASCONCELOS, Pedro Fernando da Costa; PEREIRA, Armando de Souza; FERNANDES, Marcus Emanuel Barroncas; CARMO, Antônio Ismael Barros doThe outbreaks of rabies in humans transmitted by Desmodus rotundus in 2004 and 2005, in the northeast of the Brazilian State of Para, eastern Amazon basin, made this a priority area for studies on this zoonosis. Given this, the present study provides data on this phenomenon in an urban context, in order to assess the possible circulation of the classic rabies virus (RABV) among bat species in Capanema, a town in the Amazon basin. Bats were collected, in 2011, with mist nets during the wet and dry seasons. Samples of brain tissue and blood were collected for virological and serological survey, respectively. None of the 153 brain tissue samples analyzed tested positive for RABV infection, but 50.34% (95% CI: 45.67-55.01%) of the serum samples analyzed were seropositive. Artibeus planirostris was the most common species, with a high percentage of seropositive individuals (52.46%, 95% CI: 52.31 52.60%). Statistically, equal proportions of seropositive results were obtained in the rainy and dry seasons (c2 = 0.057, d.f. = 1, p = 0.88). Significantly higher proportions of males (55.96%, 95% CI: 48.96-62.96%) and adults (52.37%, 95% CI: 47.35-57.39%) were seropositive. While none of the brain tissue samples tested positive for infection, the high proportion of seropositive specimens indicates that RABV may be widespread in this urban area.
