Epipelon responses to N and P enrichment and the relationships with phytoplankton and zooplankton in a mesotrophic reservoir
; ; de Almeida Castilho, Maria Carolina; Henry, Raoul ; (Aquatic Ecology, 2019) [Artigo]
The phototrophic epipelon has been suggested to play an important role in ecosystems, especially those with shallow depths; however, only a few studies have investigated this function. Nutrient availability has been shown ... -
