The Trophic state of Patagonian Argentinean lakes and its relationship with depth distribution in sediment Phosphorus
(Univ Tehran, 2014)
The parameters used to determine the trophic state of a water body are: total phosphorus (TP), transparency (Secchi disk depth) and chlorophyll a. However, these parameters show strong seasonal fluctuations which may hinder ...
Trophic State Evolution over 15 Years in a Tropical Reservoir with Low Nitrogen Concentrations and Cyanobacteria Predominance
Anthropic eutrophication is one of the most widespread problems affecting water quality worldwide. This condition is caused by excessive nutrient inputs to aquatic systems, and one of the main consequences is accelerated ...
Comparação de dois índices de determinação do grau de trofia nas águas do Baixo Rio São José dos Dourados, São Paulo, Brasil
This Study conducted from February 2010 to January 2011, in the Baixo São José dos Dourados (BSJD), in the Unidade de Gerenciamento de Recursos Hídricos (UGRHI) 18, in order to determine the trophic level of the water ...
Science for a wilder Anthropocene: Synthesis and future directions for trophic rewilding research
(Natl Acad Sciences, 2016-01-26)
Trophic rewilding is an ecological restoration strategy that uses species introductions to restore top-down trophic interactions and associated trophic cascades to promote self-regulating biodiverse ecosystems. Given the ...
The trophic role of lutjanid fish and impacts of their fisheries in two ecosystems in the Gulf of Mexico
(Journal of Fish Biology, 1998)
The trophic role of snappers was evaluated on the continental shelves of the south-western Gulf of Mexico and the Yucatan in the south-eastern Gulf of Mexico. Mass-balanced, steady-state trophic models of the two ecosystems ...
Phytoplankton as trophic descriptors of a series of Mediterranean reservoirs (Catalonia, Spain)
The aim of this work was to determine the ways in which the associations of phytoplankton (species, classes, and functional groups) responded to different trophic states in a series of Mediterranean reservoirs (La Llosa ...
Assessment of the efficiency of a trophic state index in determining the water quality of public water supply reservoirs
(Assoc Brasileira Engenharia Sanitaria Ambiental, 2018-07-01)
The aim of this study consists in the evaluation of the trophic state index (IET) efficacy as a tool in the water quality analysis of three reservoirs. The IET was calculated based on water transparency in the reservoir ...
Nutrient reference concentrations and trophic state boundaries in subtropical reservoirs
(IWA PUBLISHINGLONDON, 2012)
Nutrient criteria as reference concentrations and trophic state boundaries are necessary for water management worldwide because anthropogenic eutrophication is a threat to the water uses. We compiled data on total phosphorus ...
Measuring q-bits in three-trophic level systems
(Elsevier Science BvAmsterdamHolanda, 2007)
