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 ...
Periphyton nutrient content, biomass and algal community on artificial substrate: response to experimental nutrient enrichment and the effect of its interruption in a tropical reservoir
(2018-04-01)
Periphyton plays an important functional role in the retention of nutrients in aquatic ecosystems, especially phosphorus. We evaluated the effects of enrichment with N and P and the effect after 20 days of no additional N ...
Peat humic substances enriched with nutrients for agricultural applications: competion between nutrients and non-essential metals present in tropical soils
(Elsevier B.V., 2010-05-15)
Improved agricultural productivity, and reduction of environmental impacts, require studies of the interactions between different soil components. Fertilizers marketed as “organic” or “natural”, such as peats or humic ...

Fatores reguladores da decomposição foliar: uma abordagem sobre fragmentadores e decompositores
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2017-02-21)
According to the River Continuum Concept, in small rivers, corresponding to ~ 80% of river basins, the main energy source for the trophic chain is the material produced in riparian zones, especially leaves. This material ...
Shrimp farming influence on carbon and nutrient accumulation within Peruvian mangroves sediments
(Elsevier, 2020)
In order to investigate the influence of shrimp farming activities on carbon and nutrient accumulation, sediment cores were collected from two areas at different distances from shrimp farms within a Peruvian mangrove ...
