Submerged macrophytes height estimation by echosounder data sample
(2012-12-01)
Traditional methods of submerged aquatic vegetation (SAV) survey last long and then, they are high cost. Optical remote sensing is an alternative, but it has some limitations in the aquatic environment. The use of echosounder ...

Uncertainty analysis of a spatiotemporal model for submerged vegetation colonization
(2012-01-01)
This work presents an uncertainty analysis applied to the results of an ecological model. This model describes the development of submerged macrophytes colonization in a brazilian reservoir, between Sao Paulo and Parana ...
Antagonistic effects of a native apple snail on other snails and macroinvertebrates in Southern Pampas waterbodies: a mesocosm approach
(Elsevier Gmbh, 2019-09)
Macroinvertebrates represent an important component of communities and trophic webs of freshwater ecosystems. Pomacea canaliculata (family Ampullariidae), an invasive apple snail native to the Pampas ecoregion, acts as a ...
Arquitetura do habitat influenciando a composição taxonômica de microcrustáceos: Um estudo de caso sobre cladocera de águas continentais (Crustacea Branchiopoda)
(2016-02-01)
Environmental complexity is considered a key factor for diversity enhancement in aquatic ecosystems. Macrophyte stands are a major contributor for this complexity due to their differential architectures. Nevertheless, the ...
Aquatic macrophyte distribution in relation to water and sediment conditions in the Itaipu Reservoir, Brazil
(Kluwer Academic Publ, 1999-11-01)
Aquatic macrophyte community distribution along the eastern shoreline of the Itaipu Reservoir (one of the South America's largest impoundments) is described in relation to limnological and sedimentological factors. The ...
