4. The agricultural impact of pesticides on Physalaemus cuvieri tadpoles (Amphibia: Anura) ascertained by comet assay
ABSTRACT Amphibians inhabiting agricultural areas are constantly exposed to large amounts of chemicals, which reach the aquatic environment during the rainy season through runoff, drainage, and leaching. We performed a comet assay on the erythrocytes of tadpoles found in the surroundings of agricultural fields (soybean and corn crops), where there is an inte

8. Caracterização da comunidade de mamíferos de médio e grande porte em paisagem agrícola fragmentada / Characterization of the mid and large bodied mammal community in a fragmented agricultural landscape
Agricultural expansion is a major cause of habitat fragmentation, leading to a reduction and isolation of natural areas. It is therefore important to understand the role of agricultural landscape structure and dynamics in maintaining local biodiversity. We aimed to describe how the structure and dynamics of an agricultural landscape influenced the community

10. AplicaÃÃo do MÃtodo das Isozonas na ObtenÃÃo das EquaÃÃes IDF de Chuvas Intensas dos MunicÃpios de Juazeiro do Norte, Barbalha e Crato - CE / Isozones Method applied in the obtention of the heavy rainfall IDF equations of the Juazeiro do Norte, Barbalha and Crato (CE) municipalities.
The increase in use of urban and rural land demands knowledge on statistically treated data on intensity, duration and frequency of heavy rainfall, allowing better forecasting of peak flow rates - used in the design of drainage networks. The damage caused by flooding of urban and rural areas are only avoided by well dimensioned drainage works, resulting in c
