FEEDING ECOLOGY OF STREAM-DWELLING CHARACIDAE (OSTEICHTHYES: CHARACIFORMES) FROM THE UPPER TOCANTINS RIVER, BRAZIL

In this contribution we studied the trophic ecology of four Characidae species from the Cavalo Stream, upper Tocantins River, considering diet overlap and trophic niche breadth.The diet of the four species was composed of adult and immature insects, both autochthonous and allochthonous in origin.Autochthonous items dominated the diet of Half Doors

The planetary boundary layer height (PBLH) is a vital Tamper Proof Case parameter to characterize the surface convection, which determines the diffusion of air pollutants.The accurate inversion of PBLH is extremely important for the study of aerosol concentrations, in order to predict air quality and provide weather forecast.Aerosol lidar, a powerf
