Efeitos de peixes bentívoros e macrófitas aquáticas submersas sobre o crescimento de microalgas perifíticas em lagos rasos: um experimento de mesocosmo
(Universidade Federal do Rio Grande do NorteBrasilUFRNEcologia, 2016-12-02)
Shallow lakes may present an alternation of stable states, between a clear water state dominated by submerged aquatic macrophytes, and a turbid water state dominated by phytoplankton. In shallow lakes theory, benthivorous ...
Holocene paleolimnological reconstruction of a high altitude Colombian tropical lake
(Brasil, 2014)
Aquatic environments in the high-Andean may be quite vulnerable to climatic conditions and hydrological processes (precipitation/evaporation) that have the potential to alter water levels and chemistry. This study reconstructs ...
Efeitos de peixes onívoros planctívoros e bentívoros em lagos tropicais
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ECOLOGIA, 2018-04-27)
Planktivorous and benthivorous fish may promote the increase of phytoplankton
biomass and turbidity by suppression of zooplankton, resuspension of sediment
and recycling or translocation of nutrients. These effects are ...
Historia ambiental de los lagos someros de la llanura Pampeana (Argentina) desde el Holoceno medio: inferencias paleoclimáticasEnvironmental history of pampa plain shallow lakes (Argentina) since middle Holocene: Paleoclimatic inferences
(Asociacion Argentina de Sedimentologia, 2014-07)
En este trabajo se presenta un estudio paleolimnológico basado en el análisis de múltiples indicadores en múltiples sitios con el objetivo de reconstruir la historia evolutiva de cinco lagos someros de la llanura Pampeana ...
A radiação ultravioleta nos ecossistemas aquáticos e seus impactos nas diferentes espécies: uma revisão bibliográfica
(Universidade Federal de Minas GeraisUFMG, 2013-03-16)
During the last years, it was observed a great reduction in the thickness of the ozone layer and thereby become visible effects caused by incidence of ultraviolet rays. The increase of deforestation and erosion, are ...
Glacier melting and stoichiometric implications for lake community structure: zooplankton species distributions across a natural light gradient
(Wiley, 2013-02)
Glaciers around the globe are melting rapidly, threatening the receiving environments of the world´s fresh water reservoirs with significant changes. The meltwater, carried by rivers, contains large amounts of suspended ...
Dinámica de especies químicas de importancia ecológica en el sistema del río Paraná Medio: influencia de las fases hidrológicas y relaciones con el fitoplancton
(2016-03-14)
Se evaluó la dinámica de nutrientes y materia orgánica disuelta cromofórica (MODC) en el sistema del río Paraná Medio, considerando las fluctuaciones hidrosedimentológicas y las relaciones con el fitoplancton. Desde el río ...
Adição de policloreto de alumínio e remoção de peixes bentívoros como técnicas de restauração de lagos rasos do semiárido brasileiro
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ECOLOGIA, 2015-02-03)
Eutrophication is the most common cause of water quality degradation in the
world. This process occurs by excessive nutrients inputs, nitrogen and phosphorus, to
the aquatic systems resulting in algal and cyanobacterial ...
