| Durante dois anos, de junho/93 a maio/95, contagens de moscas-dos-chifres foram realizadas em dois rebanhos Nelore criados extensivamente na fazenda Nhumirim, sub-região da Nhecolândia, Pantanal, MS. Os rebanhos possuíam 40 e 60 vacas, mantidas sem tratamento inseticida durante o estudo. Contagens foram realizadas duas semanas consecutivas por mês, por observadores a cavalo, em pelo menos 50% dos animais em cada rebanho. Foram observados dois picos populacionais anuais da mosca, após o início (novembro/dezembro) e final (maio/junho) do período chuvoso. A presença de moscas foi observada durante todo o estudo, em pelo menos 64% dos animais. Infestações médias não excederam 85 moscas/animal e permaneceram abaixo de 35 moscas/animal na maior parte do estudo.... |

| The somatic cell count (SCC) of refrigerated raw milk reflects the occurrence of mastitis in the herd and the management of rural property. Therefore, this study aimed to evaluate the SCC of the refrigerated raw milk and its determinant factors in dairy properties of Viçosa, State of Minas Gerais. Monthly, milk samples were taken from 44 cooling tanks during 2012. A structured questionnaire was applied to evaluate the production and management characteristics of the herds. There was a significant variation (p < 0.05) in the mean SCC of the milk, which was lower from June to August. Higher mean SCC and percentages of samples above the limit set by the legislation were observed in months of higher rainfall and ambient temperature (p < 0.05). Mechanical... |

| ABSTRACT The Guayas estuary in Ecuador is the largest estuarine ecosystem on the Pacific coast of South America. This estuary provides nursery and fisheries habitats, as well as filtering and detoxification services provided by suspension feeders, vegetation, and wetlands. We used oceanographic and meteorological observations to understand the hydrodynamic variability of two areas in the inner part of the estuary, Manglares de Churute and Estero Salado, from February 2016 to February 2017. Churute has less anthropogenic impacts than Estero Salado, which is currently uncoupled from river flow and highly influenced by Guayaquil, the second largest city in Ecuador, and adjacent shrimp pond effluents. The influences from the ocean and river on Churute include... |
