13. RIVER DREDGING: WHEN THE PUBLIC POWER IGNORS THE CAUSES, BIODIVERSITY AND SCIENCE
Resumo O desassoreamento de rios, geralmente, é resolvido através da dragagem dos sedimentos depositados em seu leito, utilizando diversas técnicas. Tratando de um caso concreto, objetiva-se expor a falta de critérios técnicos para a execução de tal intervenção, os impactos para o rio, biota aquática e a sua real necessidade. São apresentados aspe

14. Potencialidade dos pavimentos permeáveis na melhoria da qualidade da água do escoamento superficial: uma revisão
Resumo O escoamento superficial pode acarretar em enchentes urbanas e no aumento da carga de poluentes de corpos d’água. O aumento da carga de poluentes é devido ao fato de o escoamento superficial percorrer sobre pavimentos e calçadas e, dessa forma, transportar os poluentes depositados nesses locais. A percolação do escoamento superficial nos pavim

15. Application of indices for water resource systems stress assessment
RESUMO O presente artigo teve como objetivo apresentar uma metodologia para avaliação do estresse hídrico de sistemas de recursos hídricos por meio de índices. Neste caso, aplicou-se a metodologia proposta ao Sistema Cantareira, um dos principais sistemas produtores de água da Região Metropolitana de São Paulo (RMSP). Foram utilizados para esta aval

16. SPATIALIZATION OF THE ANNUAL MAXIMUM DAILY RAINFALL IN SOUTHEASTERN BRAZIL
ABSTRACT Extreme rainfall can lead to heavy damage and losses, such as landslides, floods and agricultural productivity as well as the loss of human and animal lives. To mitigate these losses, water resources management policies are needed, among other goals, to study and predict the frequency of such events in a given region to minimize their harmful effect

17. Escapes of non-native fish from flooded aquaculture facilities: the case of Paranapanema River, southern Brazil
ABSTRACT Non-native species are a major driver of biodiversity loss. Aquaculture activities play a key role in introductions, including the escape of fishes from fish farm facilities. Here, the impact of flooding due to El Niño rains in 2015/2016 in the Lower and Middle Paranapanema River basin, southern Brazil, was investigated by evaluating fish escapes f

18. Fish population responses to hydrological variation in a seasonal wetland in southeast México
ABSTRACT Hydrological variation differently affects fish species. In the present study, the response of local populations of 13 fish local species to hydrological variation in a tropical wetland was evaluated. The objectives were to analyze the abundance response of fish species with distinct life history strategies and to assess the role of hydrological var

19. Influence of hydrology on the fish body condition in a large subtropical floodplain
ABSTRACT With the objective of finding fluctuations on fish body condition in the Middle Paraná River floodplain in different hydrological scenarios, this attribute was analyzed in several trophic groups of a secondary floodplain channel and its associated lakes between 2010 and 2012. Standardized residuals generated by length-weight regressions were calcul

20. Spider assemblage (Arachnida: Araneae) associated with canopies of Vochysia divergens (Vochysiaceae) in the northern region of the Brazilian Pantanal
ABSTRACT This study describes the composition and temporal variation of the spider assemblage (Arachnida: Araneae) associated with canopies of Vochysia divergens Pohl. (Vochysiaceae) in the northern region of the Brazilian Pantanal. Three V. divergens plants were sampled in 2004, at each seasonal period of the northern Pantanal (high water, receding water, d

21. Reproductive seasonality of Geophagus steindachneri Eigenmann & Hildebrand, 1922 (Perciformes: Cichlidae) in a tropical mountain river
Reproductive seasonality in tropical freshwater fishes is strongly influenced by rainfall. In lowlands, floods spill laterally to floodplains and fishes usually breed during the flooding season. In mountain rivers, floods are sudden and flush out aquatic organisms. Fishes in mountain rivers usually breed during dry seasons, what has been hypothesized as a st

22. Progression of the load of waterborne and intestinal parasitic diseases in the State of Amazonas
In the State of Amazonas, Brazil, urban expansion together with precarious basic sanitation conditions and human settlement on river banks has contributed to the persistence of waterborne and intestinal parasitic diseases. Time series of the recorded cases of cholera, typhoid fever, hepatitis A and leptospirosis are described, using data from different level

23. Is the population of Crotalus durissus (Serpentes, Viperidae) expanding in Brazil?
Crotalus durissus are found from Mexico to northern Argentina in a highly disjunct distribution. According to some studies, this species is prone to occupy areas disturbed by human activities and floods comprise a plausible method of dispersal as inferred for some North American rattlesnakes. Based on the literature, it seems plausible that Crotalus durissu

24. Temporal variation in the composition of ant assemblages (Hymenoptera, Formicidae) on trees in the Pantanal floodplain, Mato Grosso do Sul, Brazil
Temporal variation in the composition of ant assemblages (Hymenoptera, Formicidae) on trees in the Pantanal floodplain, Mato Grosso do Sul, Brazil. In this paper we investigate how seasonal flooding influences the composition of assemblages of ants foraging on trees in the Pantanal of Mato Grosso do Sul. During the flood in the Pantanal, a large area is cove
