We analyzed the infestation levels of Excorallana berbicensis on Acestrorhynchus falcirostris, Ageneiosus ucayalensis, Geophagus proximus, Hemiodus unimaculatus, Psectrogaster falcata and Serrasalmus gibbus in a reservoir in the Araguari River basin, northern Brazil, during the dry and rainy seasons. For P. falcata, the infestation levels due to E. berbicensis were greater during the rainy season. For all the species studied, the peak parasite prevalence was in the month of highest rainfall levels and there were two peaks of parasite abundance: one in the month with highest rainfall level and the other in the month of transition from the rainy season to the dry season. In these hosts, around 70% of the E. berbicensis specimens were collected during the rainy season. The body conditions of the hosts also did not suffer any seasonal influence. Despite the differences in seasonal rainfall levels, there was no fluctuation in transparency, turbidity, pH, electric conductivity, temperature and dissolved oxygen levels in the water, due to the stability of these parameters during the seasonal cycle investigated in this artificial Amazon ecosystem. This was the first report on the seasonality of infestation by E. berbicensis associated with fish. |

ABSTRACT: Forest patch occupancy by Undulated Tinamou (Crypturellus undulatus) in west of Pantanal da Nhecolândia, Corumbá, MS. The deforestation process and changes in the structure of forest habitats in Pantanal have caused decline in the biological diversity. The goal of this study was to evaluate the influence of landscape and forest patches structure on the occupancy probabilities of Undulated Tinamou Crypturellus undulatus (Temminck, 1815) in the western ?Pantanal da Nhecolândia?, Mato Grosso do Sul, Brazil. From January to October 2008 we sampled 40 sites in forest patches in four areas of different ecological and management conditions. In each point we obtained landscape (area and distance between forest patches) and habitat variables (understory and litter biomass), as well as presence/absence data of C. undulatus. The highest probabilities of occupation were obtained in large forest patches (> 800 ha), connected (<100 m away from other patches), with dense understory (> 0.8 kg / m3 ) and with accumulated litter biomass (> 1.5 kg / m2). The results suggest that human impacts (deforestation, range thinning of cordilheiras, replacement of native vegetation by exotic pastures, and changes in structure of forest habitats due to livestok action) in Pantanal negatively influence the probabilities of occupancy by C. undulatus. Management practices that help the conservation of suitable habitats for wildlife are fundamental to achieve and maintain the ecological sustainability of cattle ranches in the Pantanal wetland. RESUMO: A fragmentação e as alterações na estrutura dos habitats florestais no Pantanal têm promovido significativas mudanças nos processos ecológicos e diversidade biológica regional. Este estudo objetivou avaliar como as variáveis da paisagem e do habitat afetam as probabilidades de ocupação de manchas florestais pelo jaó Crypturellus undulatus (Temminck, 1815) no oeste do Pantanal da Nhecolândia, Mato Grosso do Sul. De janeiro a outubro de 2008 foram amostrados 40 pontos distribuídos em manchas florestais em quatro áreas com diferentes condições de manejo. Nestes pontos foram obtidas variáveis da paisagem (área e distância entre as manchas florestais) e do habitat (biomassas de sub-bosque e serrapilheira), bem como dados de presença/ausência de C. undulatus. As maiores probabilidades de ocupação foram obtidas em manchas florestais grandes (> 800 ha), conectadas (< 100 m de distância de outras manchas), com sub-bosque denso (> 0,8 kg/m3 de biomassa) e com elevado acúmulo de biomassa de serrapilheira (> 1,5 kg/m2 ). Os resultados sugerem que as intervenções humanas na paisagem (raleamento de cordilheiras, substituição de pastagens nativas por pastagens cultivadas exóticas e alteração na estrutura do habitat florestal por impacto do forrageio e pisoteio de gado bovino) no Pantanal podem afetar negativamente as populações de C. undulatus. Práticas de manejo que auxiliem a conservação de habitats favoráveis à vida selvagem são fundamentais para alcançar ou manter a sustentabilidade ecológica em fazendas de pecuária no Pantanal.
