Limnological studies on a shallow reservoir in western Venezuela (Tulé Reservoir)

A two-year field study and evaluation of water quality and trophic state of a large shallow drinking water reservoir in Shanghai, China

“…Either COD Mn or TOC in the studied reservoir showed a strong seasonal variation, similar to a Swedish catchment [39]. Even today researchers are not certain about the limiting nutrient mechanism in a water body [28]; however, they tend to assume that P limitation is more reasonable in most water systems over N [2,8,28]. TN and TP concentrations in the studied reservoir were 749 and 46 μg/L, respectively, similar to those in the Itupararanga Reservoir [28].…”

“…Total phosphorus (TP), chlorophyll-a (Chla), total nitrogen (TN), chemical oxygen demand in manganese (COD Mn ), and transparency (SD) are parameters frequently used in water quality and trophic evaluation models [8]. Carlson firstly proposed the trophic state indices (TSI) to determine eutrophication level of lakes using TP, Chla, TN, COD Mn, and SD as major parameters [9]; subsequently, TSI have been widely used in lakes and reservoirs [10][11][12][13][14][15][16].…”

Limiting factors for phytoplankton growth in subtropical reservoirs: the effect of light and nutrient availability in different longitudinal compartments

“…In addition, cyanobacteria are of widespread occurrence in Brazilian waterbodies and are able to fix nitrogen through the heterocysts (Sprõber et al 2003, Fiore et al 2005, Figueredo and Giani 2009, Haande et al 2011. For these reasons, phosphorus limitation is frequently reported in tropical and subtropical reservoirs (Gianesella-Galvão 1985, Páez 2001. In recent years, however, a limitation chain with N, P, and light was proposed for phytoplankton.…”

Physical limnology of a typical subtropical reservoir in south China

“…Limnological characterization is a fundamental tool for designing conservation and management policies for lakes and reservoirs (Paez et al 2001). In addition to chemical and biological factors, some physical factors also affect water quality.…”
