Hydrochemistry and trophic state change in a large reservoir in the Brazilian northeast region under intense drought conditions
(Page Press Publications, 2017)
The study shows changes on physical and chemical water parameters and of trophic state in a large reservoir in the Brazilian semiarid region following decreasing reservoir volume due to rainfall shortage during four ...
Locally tuned model to map the chlorophyll-a and the trophic state in Porto Primavera reservoir using MODIS/Terra images
(Springer, 2018-04-01)
In this work we hypothesized that the damming of a rural River for hydropower generation, altering the water retention time should increase the chlorophyll-a (Chl-a) concentration, consequently changing the trophic status. ...
Inland water's trophic status classification based on machine learning and remote sensing data
(2020-08-01)
In this work, we tested machine learning algorithms in classifying waters in a reservoir cascade with basis in trophic state. The classification was done through remote sensing reflectance (Rrs) measurements collected in ...
Monitoring of aquaculture in continental reservoirs using the trophic status index
(Univ Federal Mato Grosso, 2019-05-01)
Aquaculture is the fastest growing activity among food production sectors, however, its practice can cause environmental impacts, in case if a monitoring plan is not applied. The objective of the present study was to ...
Triatoma rubrovaria (Blanchard, 1843) (Hemiptera, Reduviidae, Triatominae) II: Trophic Resources and Ecological Observations of Five Populations Collected in the State of Rio Grande do Sul, Brazil
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 2020)
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 ...
Estimation of chlorophyll-a concentration from optimizing a semi-analytical algorithm in productive inland waters
(2018-02-01)
The high nutrient concentrations coming from non-point and point pollution have been linked to algae blooms, especially in hydroelectric plant reservoirs, due to higher residence time compared to rivers. The monitoring of ...
Bioindicators of climate and trophic state in lowland and highland aquatic ecosystems of the Northern Neotropics
(Revista de Biologia Tropical, 2013-06)
Chironomids, diatoms and microcrustaceans that inhabit aquatic ecosystems of the Northern Neotropics are abundant and diverse. Some species are highly sensitive to changes in water chemical composition and trophic state. ...
Trophic state index (TSI) and physico-chemical characteristics of a shallow reservoir in southeast Brazil
(2016-01-01)
This paper presents the trophic state index (TSI) and water physico-chemical characteristics of a shallow tropical reservoir located in southeast Brazil. It describes a study held over a hydrological and diurnal period, ...
