Efeitos de peixes zooplanctívoros e onívoros sobre a resposta de comunidades planctônicas à fertilização por nutrientes
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em EcologiaBioecologia Aquática, 2009-05-29)
The food chain theory predict that presence of omnivory prevent the trophic cascade and could be a strong stabilizing factor over resource and consumer community dynamics, and that the nutrient enrichment destabilize ...
Plant Physiological Responses to Nutrient Solution: An Overview
(2018-03-20)
Being sessile, plants developed adaptive and flexible strategies for nutrient acquisition. Localized deficiency or oversupply of many nutrients induces morphological and physiological adaptations, such as gas exchange, ...
Litterfall and nutrient transfer dynamics in a successional gradient of tropical dry forest in Colombia
(Universidad de Costa Rica, 2023)
Current and predicted global change impacts of UVR, temperature and nutrient inputs on photosynthesis and respiration of key marine phytoplankton groups
(Elsevier Science, 2014-12)
Multiple stressors are altering primary production in coastal and estuarine systems; however, it is difficult to predict their combined impacts due to the scarcity of multifactorial experiments. Photosynthesis, respiration, ...
Dynamics of above- and below-ground biomass and nutrient accumulation in an age sequence of Nothofagus antarctica forest of southern Patagonia
(Elsevier Science, 2006-09)
Nothofagus antarctica (Forster f.) Oersted is a deciduous tree species, which naturally grows on poorly drained or drier eastern sites in the Andes Mountain near Patagonian steppe. Above- and below-ground biomass and ...
Nutrient dynamics in the Paraná River Delta: relationship to the hydrologic regime and the floodplain wetlands
(Elsevier, 2022-04)
South America contains the most extensive freshwater wetlands in the world, associated with the floodplains of the Amazon, Orinoco and Paraná rivers. The Paraná River delta is a large wetland system strongly influenced by ...
O papel da competição por luz e da troca de nutrientes na interação entre plantas
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2003-12-03)
At this work we present two models to describe de growth dynamics of interacting plants. The first system that we have used describes de water dynamics, and then relates it with the cations in the ground and with the biomass ...
Effects of alternative silvicultural systems on litter decomposition and nutrients dynamics in sub-Antarctic forests
(Springer, 2019-06-12)
Forest harvesting is one of the main economic practices in South Patagonia. The impacts produced by forest harvesting have been studied by numerous investigations. And it is known that forest harvesting affects the ...
