Floristic surveys from mesotrophic and eutrophic environments have reported species from the families Salviniaceae, Cabombaceae, Nymphaeaceae, Poaceae, Cyperaceae and Lentibulariaceae (Matias, Amado, & Nunes, 2003; Henry-Silva, Moura, & Dantas, 2010; Mormul et al.
Once the thermocline sets up in early summer, you can mostly cross out water below the lower level of the thermocline, which often lacks oxygen in eutrophic and mesotrophic waters.
The registered values of Chl-a at El Neusa reservoir fluctuated within a range that goes from oligo to mesotrophic condition according to concentrations established for trophic status indices (TSIs) from lentic ecosystems (Carlson & Simpson, 1996; Brown & Simpson, 2001).
Predation can be responsible for the breakdown of bacterioplankton blooms and the temporal changes in phytoplankton structure in a mesotrophic lake (Hennes and Simon, 1995).
In Sao Paulo State, where introduction occurred towards the end of the 1980s, this species is now widespread in the reservoirs of the Parana River basin (Matsumura-Tundisi and Silva, 2002) with high abundance and dominance in mesotrophic and eutrophic systems (Silva, 2011).
The lake trophic state has changed in the following stages: naturally mesotrophic (until the late 1950s), eutrophic (late 1950s-mid-1980s), hypertrophic (mid-1980s-2002) (Kangro et al.
High abundance of larvae and juveniles of gizzard shad (Dorossoma cepedianum) leads to a reduction in the densities of total zooplankton in mesotrophic environments, which interferes with the recruitment of sport fishes in four reservoirs.
