Ecomorphological correlates of twenty dominant fish species of Amazonian floodplain lakes / Correlações ecomorfológicas de vinte espécies de peixes dominantes em lagos de várzea da Amazônia

Abstract Fishes inhabiting Amazonian floodplain lakes exhibits a great variety of body shape, which was a key advantage to colonize the several habitats that compose these areas adjacent to the large Amazon rivers. In this paper, we did an ecomorphological analysis of twenty abundant species, sampled in May and August 2011, into two floodplain lakes of the lower stretch of the Solimões River. The analysis detected differences among species, which could be probably associated with swimming ability and habitat use preferences.

Resumo Os peixes que habitam os lagos de várzea da Amazônia apresentam morfologias bastante diversas, possibilitando a exploração bem sucedida dos diferentes habitats que formam estas áreas adjacentes aos grandes rios amazônicos. Neste artigo, relatamos os resultados de uma análise ecomorfológica de vinte espécies abundantes, coletadas em maio e agosto de 2011, em dois lagos das várzeas do trecho inferior do rio Solimões. As analises indicaram diferenças entre as espécies como função do atributos ecomorfológicos, provavelmente associadas com a capacidade natatória e com preferências por habitat.

Honeybees and caterpillars: epidemiology of accidents involving these animals in the Criciúma region, southern Santa Catarina State, Brazil

The present study aimed to acquire knowledge regarding some aspects of the epidemiology and injuries provoked by honeybees and caterpillars in southern Santa Catarina State, Brazil. Epidemiological information concerning accidents with both animals was prospectively collected from the System of Injury Notification Information (SINAN) files of the Municipal Health Secretary of the Criciúma region, Brazil. Between 1994 and 2006, 203 cases of accidents were registered, 149 provoked by honeybees (73.39%) and 54 by caterpillars (26.61%). The majority of the victims (200 cases) presented full recovery, two cases presented sequelae after recovery, and only one death was recorded in a case involving honeybee injury. The high frequency of victim recovery suggests that the public health system is efficient and the low frequency of sequelae after recovery also suggests that this system is fast and well developed. However, the low number of allergic people in this population should be considered as well as the severity level of the recorded accidents.(AU)
