Photochemical activity of PSII of tropical phytoplankton communities of Southern Brazil exposed to solar radiation and nutrient addition
(Elsevier Science Inc, 2014)
We carried out short- and mid-term incubations to assess the combined impact of solar ultraviolet radiation (UVR, 280-400nm) and nutrient addition on tropical phytoplankton communities from BabitongaBay, Southern Brazil. ...
Native and alien herbaceous plants in the Brazilian Cerrado are (co-)limited by different nutrients
(2016-03-01)
Background and aims: The diverse flora of the Brazilian Cerrado is threatened by agricultural expansion, nutrient enrichment and invasion of alien plants. We performed a fertilization experiment to investigate the nature ...
Exposure of Typha domingensis to high concentrations of multi-metal and nutrient solutions: Study of tolerance and removal efficiency
(Elsevier Science, 2021-01)
This work studied the effects of nutrients on metal tolerance, removal efficiency, and metal accumulation in tissues of T. domingensis. This macrophyte was exposed to solutions of Cr(III) + Ni + Zn at extremely high ...
Perdas de nutrientes associadas ao escoamento e aos sedimentos erodidos em encostas sob plantio direto
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2022-01-31)
No-tillage (NT) is widely used in areas of grain crops in tropical and subtropical regions.
However, crops fields under NT with low phytomass addition and without runoff control
practices are highly susceptible to ...

Compositional Nutrient Diagnosis (CND) Applied to Grapevines Grown in Subtropical Climate Region
(Mdpi, 2020-09-01)
Soil analysis is used to estimate nutrient availability, but nutrient concentrations are not always related to yield in most fruit plants, including grapevines. Thus, additional multivariate mathematical models, such as ...
Effects of nutrient enrichment on epipelic diatom assemblages in a nutrient-rich lowland stream, Pampa Region, Argentina
(Springer, 2015-09-03)
We analyzed the diatom assemblages inhabiting the epipelic biofilm of a Pampean stream, characterized by their high basal nutrient levels, when exposed to a continuous surplus of inorganic nutrients. An in situ experience ...
