Hydrological impacts of precipitation extremes in the Huaihe River Basin, China
Precipitation extremes play a key role in flooding risks over the Huaihe River Basin, which is important to understand their hydrological impacts. Based on observed daily precipitation and streamflow data from 1958 to 2009, eight precipitation indices and three streamflow indices were calculated for the study of hydrological impacts of precipitation extremes. The results indicate that the wet c...
متن کاملIchthyofauna of two streams (silted and reference) in the Upper Paraná river basin, Southeastern Brazil.
In this study the fish assemblages of the silted Aguas Claras stream (AC) was compared with that of a reference, the São Carlos stream (SC), so as to identify potential fish indicators of integrity or degradation. Both streams, located about 5 km from one another, are part of the Upper Paraná river basin, Brazil, and present similar physiographical features. Twenty-one species were collected in...
متن کاملKaryotypic variability in Iheringichthys labrosus (Teleostei, Pimelodidae) from the Tibagi River basin (Paraná State, Brazil).
Cytogenetic analyses were carried out in a populational sample of Iheringichthys labrosus from the Guaraúna River (Upper Tibagi River; Paraná State, Brazil) in order to provide a karyotypic comparison with another previously studied population from the Lower Tibagi River, characterized by the presence of 32m + 8sm + 6st + 10a (2n = 56, FN = 102) and occurrence of supernumerary chromosomes (80% ...
متن کاملRecent Changes in Temperature and Precipitation Extremes in an Ecological Reserve in Federal District, Brazil
The main objective of this study is to provide information on trends, in local scale, using records of daily temperature and precipitation of a single weather station in an ecological reserve of the savanna biome in Federal District/Brazil, analyzing different extreme climatic indices. The extreme temperature indices have identified that the days are getting warmer and the nights are cooler at ...
متن کاملReproductive seasonality of fishes from a lotic stretch of the Grande River, high Paraná river basin, Brazil.
We searched for correlations between water level, rainfall, temperature, and reproductive activity of fishes in a lotic stretch of the Grande River below the Volta Grande Dam. Gillnets were used to catch the fish on six field journeys made bimonthly between April 1998 and February 1999. Fish gonads were classified according to maturation grade and the amount of mature or spent gonads was correl...
