Prediction of colonization by macrophytes in the Yaciretá reservoir of the Paraná River (Argentina and Paraguay) BJB
NEIFF,J. J.; POI DE NEIFF,A. S. G.; PATIÑO,C. A. E.; BASTERRA DE CHIOZZI,I..
The potential colonization by anchored plants (PCAP) and the potential areas for initial colonization of free floating plants were estimated during the early filling phase for the Yaciretá reservoir. In order to obtain the PCAP, the observed maximum depth of colonization of the anchored macrophytes before impoundment and the hypsographic curves were used. The species inhabiting the pre-impoundment area were classified according to the different bioforms before the inclussion in the analysis. The areal extent of PCAP (from depths between 0-4 m) could reach 275 km² at 76 m above sea level (current water level), whereas at 82 m above sea level (final filling level) the littoral zone will be increased by about 21.5%. The potential area for geophytes was...
