Measuring complexity in three-trophic level systems
(ELSEVIER SCIENCE BV, 2009)
This essay is a trial on measuring complexity in a three-trophic level system by using a convex function of the informational entropy. The complexity measure defined here is compatible with the fact that real complexity ...
Estimation of trophic states in warm tropical lakes and reservoirs of Latin America by using GPSS simulation
(2006)
This paper proposes a stochastic simulation model to determine the boundaries of the trophic states of warm-water tropical lakes and reservoirs in Latin America based on statistical correlation and MonteCarlo techniques. ...
Estimation of chlorophyll-a concentration and the trophic state of the Barra Bonita hydroelectric reservoir using oli/landsat-8 images
(International Journal Of Environmental Research And Public Health, 2015)
Reservoirs are artificial environments built by humans, and the impacts of these environments are not completely known. Retention time and high nutrient availability in the water increases the eutrophic level. Eutrophication ...
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

Variabilidade da qualidade da água e do estado trófico do reservatório do Vacacaí Mirim
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2011-07-15)
The construction of several reservoirs to meet multiple uses has become essential to human societies. The Vacacaí Mirim s reservoir is used primarily for human supply, accounting for 40% of the Santa Maria water supply. ...
Drivers of phytoplankton diversity in patagonian and antarctic lakes across a latitudinal gradient (2150 km): The importance of spatial and environmental factors
(Springer, 2015-04)
We investigated the phytoplankton structure in 60 lakes across a latitudinal gradient (2150 km), from Austral Patagonia to Antarctica, including environments ranging from oligotrophic to eutrophic. We analysed the latitudinal ...

The variability of particle backscattering coefficient in an oligo-to-hypertrophic cascading reservoir system: implications to TSM bio-optical model development
(Springer, 2016-06-01)
The particle backscattering coefficient (b(bp)) has been obtained either by equipment or semi-analytically based on relations between b(bp) and the remote sensing reflectance (R-rs). Correlation between b(bp) and R-rs can ...
