Tolerance to high temperatures in tadpoles of Leptodactylus fuscus and Hyla fuscovaria in temporary ponds (Amphibia, Leptodactylidae, Hylidae)
(1991-12-01)
In temporary ponds tadpoles of the frogs Leptodactylus fuscus and Hyla fuscovaria may be exposed to temperatures up to 40-44°C. Experimental exposure to high temperature revealed survivals after 30 min at 42°C for H. ...

Effect of fertilization in water quality and in zooplankton community in open plankton-culture ponds
(Universidade Federal de Uberlândia (UFU), 2009-01-01)
The effect of swine manure fertilization on the water quality of zooplankton artificial culture in two ponds was measured in diel cycles on different months (October 1999, January and March 2000). Fertilization affected ...

(2017-01-01)
Purpose: The purpose of this paper is to evaluate the efficiency of a duckweed pond in the polishing of a stabilization pond effluent, as well as quantify its biomass production. Once an adequate destination is given to ...
Effect of Water Exchange and Mechanical Aeration on Grow-out of the Amazon River Prawn in Ponds
(Wiley-Blackwell, 2013-12-01)
Exchange and aeration of pond water are common practices in semi-intensive freshwater prawn culture, but there is lack of scientifically based information on the results. We evaluated the effects of water flow through the ...
