Influence of environmental parameters on fish assemblage of a neotropical river with a flood pulse regime, Central Brazil. This study aims to determine which of twelve environmental parameters five physicochemical and seven hydromorphological influence on the fish assemblage structure of the lower Mortes River basin located in the Bananal floodplain of the Araguaia River basin, Central Brazil. Sampling was conducted in six stretches of m each during the high and low waters. Fish were captured using gill nets and environmental parameters were measured by portable equipment or determined visually. The co-inertia analysis indicated that two physicochemical dissolved oxygen and water transparency , and four hydromorphological channel width and depth, riparian vegetation cover and type of the riverside substrate parameters structure the fish assemblages, both driven by the regional hydrological patterns flood pulse. These results are explained by fish-environmental parameters relationship characteristic of the aquatic Neotropical systems.

Physical and chemical parameters of Pao-Cachinche reservoir Venezuela were measured in four stations S1-S4 during an eighteen months period from September to February The tributaries of this reservoir introduce high amounts of nutrients from domestic wastewaters and from poultry and pig farms located in the basin. Thermal stratification was well established throughout the study period. Mountainous topography protects the water surface from mechanical action of wind, preventing water mixing.
