ALTERATION OF NITROGEN CYCLING BY AGRICULTURAL ACTIVITIES, AND ITS ENVIRONMENTAL AND HEALTH CONSEQUENCES
(Facultad de Ciencias Naturales y Oceanográficas, Universidad de Concepción, 2005)
Diversity of photosynthetic picoeukaryotes in eutrophic shallow lakes as assessed by combining flow cytometry cell-sorting and high throughput sequencing
(Wiley Blackwell Publishing, Inc, 2019-05)
Photosynthetic picoeukaryotes (PPE) are key components of primary production in marine and freshwater ecosystems. In contrast with those of marine environments, freshwater PPE groups have received little attention. In this ...
Phytoplankton, trophic state and ecological potential in reservoirs in the State of São Paulo, BrazilFitoplâncton, estado trófico e potencial ecológico em reservatórios do estado de São Paulo, Brasil
(2019-01-01)
This study evaluated the ecological potential of reservoirs in the Brazilian state of São Paulo, having phytoplankton as a biological quality element. Integrated water column sampling was carried out in the dam, and in the ...
The phytoplankton functional groups in the reservoirs of the Cantareira System, Sao Paulo, Brazil
(Fundacao Zoobotanica Rio Grande Sul, Museu Ciencias Naturais, 2018-08-31)
This study aimed to verify if the phytoplankton community responds to different trophic states in the reservoirs of the Cantareira System, based on the distribution of phytoplankton functional groups (GFF). The samplings ...
Atmospheric correction issues for retrieving total suspended matter concentrations in inland waters using OLI/Landsat-8 image
(Elsevier B.V., 2017-05-01)
The atmospheric effects that influence on the signal registered by remote sensors might be minimized in order to provide reliable spectral information. In aquatic systems, the application of atmospheric correction aims to ...
Response of Microcystis aeruginosa BCCUSP 232 to barley (Hordeum vulgare L.) straw degradation extract and fractions
(2017-12-01)
The eutrophication of aquatic ecosystems is a serious environmental problem that leads to increased frequency of cyanobacterial blooms and concentrations of cyanotoxins. These changes in aquatic chemistry can negatively ...
Phosphorus fractionation in sediments of tropical semiarid reservoirs

Qualidade da água em um reservatório da região semiárida após a reinundação - Dourado/RN
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia AmbientalEngenharia Civil, 2021-09-06)
Extreme events of prolonged drought can aggravate the symptoms of eutrophication, increasing the concentration of nutrients in water bodies. This is due to the low water level and intermittent rivers, which remain dry ...
Microcystin-LR in Brazilian Aquaculture Production Systems
(Water Environment Federation, 2010-03-01)
The growth of aquaculture production systems, mostly the sport-fishing kind, coupled with a lack of control, brings about concerns on the quality of water and food produced. The current paper determines which factors may ...
