Formação e mineralização de substâncias húmicas desde a decomposição de macrófitas aquáticas em reservatórios tropicais com diferentes graus de trofia
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2015-07-08)
The decomposition of aquatic macrophytes is important for understanding the cycling of elements and organic matter in aquatic ecosystems. The decomposition rate is driven by biotic and abiotic factors. Thus, the aim of ...
Estrutura trófica de macroinvertebrados em riachos tropicais de pastagem
(2016-01-01)
Aim: The aim of this study was to describe the diet of stream macroinvertebrates and to determine their trophic groups. Methods: Invertebrates were sampled with D nets in three pasture streams. They were identified to genus ...
Mudanças climáticas e ciclagem de carbono na decomposição aeróbia e anaeróbia de Myriophyllum aquaticum (Vellozo) Verdecourt
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2018-02-26)
Aquatic macrophytes are key organisms in freshwater environments, as they are intrinsically linked to primary productivity, nutrient and carbon cycling and detritus formation in these environments. The temperature is one ...
A discrete interaction numerical model for coagulation and fragmentation of marine detritic particulate matter (Coagfrag v.1)
(European Geosciences Union, 2021-07)
A simplified model, representing the dynamics of marine organic particles in a given size range experiencing coagulation and fragmentation reactions, is developed. The framework is based on a discrete size spectrum on which ...
Cinética e variação molecular de substâncias húmicas formadas da lixiviação de macrófitas aquáticas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2015-08-13)
The humic substances (HS) are important to aquatic ecosystems. In this study we
investigated the kinetics and molecular variations of dissolved fulvic acids (FA) and
humic acids (HA) formed from aquatic macrophytes ...
Dominance of in situ produced particulate organic carbon in a subtropical reservoir inferred from carbon stable isotopes
(2020-12-01)
Sources of particulate organic carbon (POC) play important roles in aqueous carbon cycling because internal production can provide labile material that can easily be turned into CO2. On the other hand, more recalcitrant ...
Aspectos cinéticos da degradação aeróbia e anaeróbia de Cyperus giganteus, Eichhornia azurea e Egeria najas da lagoa do Óleo (Estação Ecológica de Jataí, Luiz Antônio, SP)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2011-06-10)
This study aimed to assess the effects of temperature on different aspects of aerobic and anaerobic degradation of aquatic macrophytes from different ecological groups: Cyperus giganteus (emergent), Eichhornia azurea (fixed ...
Bioensaios de decomposição anaeróbia de macrófitas aquáticas da lagoa do Óleo (Estação Ecológica de Jataí, Luiz Antônio - SP).
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2005-05-11)
This study aimed at investigating: i) the influence of temperature on decomposition of macrophyte detritus; ii) the importance of leaching in the dynamics of the decomposition; iii) the decomposition of different structures ...
Diet of the freshwater crab Bottiella niceforei (Schmitt & Pretzmann, 1968) (Decapoda: Trichodactylidae) and its relationship with organic matter processing in an intermittent stream of northwestern VenezuelaDieta del cangrejo dulceacuícola Bottiella niceforei (Schmitt & Pretzmann, 1968) (Decapoda: Trichodactylidae) y su relación con el procesamiento de la materia orgánica en una corriente intermitente del noroeste de Venezuela

Decomposição aeróbia de Myriophyllum aquaticum (Vell.) Verdc. e caracterização limnológica na bacia hidrográfica do rio do Monjolinho (São Carlos, SP, Brasil)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2009-06-02)
The oxidative aerobic processes contribute with large amounts of nutrients in dissolved and particulate forms for the metabolism microbial water. In that context, this study described the oxygen consumption kinetics during ...
