Plantas aquáticas e nível de infestação das espécies presentes no reservatório de Bariri, no Rio Tietê

Abstract: RESUMO -O monitoramento da vegetação aquática permite avaliar a evolução das comunidades e determinar o potencial de danos associados a essas populações. O objetivo do trabalho foi identificar as plantas aquáticas e os níveis de infestação de cada espécie, presentes no reservatório de Bariri. Foram avaliados todos os focos de vegetação aquática presente na represa (194 pontos), e os pontos foram demarcados com um aparelho de GPS. As plantas foram identificadas e realizou-se uma estimativa visual do valor geogr… Show more

“…The representativeness of families occurring in a study area can also be impaired by urbanization. Poaceae had good representation in our study, as it did in the study of Carvalho et al (2005), which evaluated the level of macrophyte infestation on the Tiete River and recorded five species (33.3% of the total), and also in the study of Henry-Silva et al (2010), which identified five species (11.36% of the total) of this family in river ecosystems of the Brazilian semi-arid region.…”

“…Observações realizadas em comunidades de plantas aquáticas nos reservatórios da Companhia Energética de São Paulo revelaram que S. auriculata, E. crassipes e P. stratiotes sempre foram citadas entre as seis espécies aquáticas de maior ocorrência e frequência nos pontos avaliados (Tanaka et al, 2002;Martins et al, 2003;Carvalho et al, 2003Carvalho et al, , 2005Cavenaghi et al, 2005). Contudo, plantas de aguapé são altamente competitivas, tendendo a dominar o ambiente aquático e prevalecendo sobre plantas como Azolla sp., P. stratiotes, Salvinia spp., etc.…”

“…Submerged macrophytes can also decrease water oxygenation, especially at night (Carvalho et al, 2005), and even unbalance the carbon/nitrogen relation due to degradation and decomposition processes with oxygen consumption (Yuan et al, 2016).…”
