The flow velocity as driving force for decomposition of leaves and twigs
The water velocity and associated physical forces affect the distribution of organisms in rivers and streams; changes in the flows can also affect the organic matter decomposition and transport of
Growth of Hydrilla verticillata (L.f.) Royle under controlled conditions
TLDR
The high temperature and light availability in most South American reservoirs (including the Porto Primavera Reservoir where it was first recorded) are suitable for H. verticillata to compete and probably displace other native aquatic macrophytes, such as Egeria najas, Egersia densa, and Cerathophyllum demersum.
Hydrologic cycle and dynamics of aquatic macrophytes in two intermittent rivers of the semi-arid region of Brazil.
TLDR
The results showed that floods and droughts are determining factors in the occurrence of macrophytes and in the structure of their aquatic communities, with lower species richness in the puddles of the river and stream subject to flood events, when compared to areas where the run-off water is retained.
Chemical constraints on new man-made lakes
TLDR
During formation of the reservoir, the incorporation and decomposition of organic matter prevailed over material exportation, thus causing the BOD concentration and the fertility of the water to decrease and the concentration of biochemical oxygen demand (BOD) and nutrients increased.
Oxygen demand during mineralization of aquatic macrophytes from an oxbow lake.
TLDR
A kinetic model of oxygen consumption during aerobic decomposition of detritus from seven species of aquatic macrophytes from Oleo Lagoon concluded that most of the oxygen demand seems to depend upon the demineralization of the dissolved carbon fraction.
Decomposition of Particulate Organic Carbon from Aquatic Macrophytes Under Different Nutrient Conditions
This study compared the decomposition of particulate organic carbon (POC) of two macrophyte species under four nutrient conditions and its fate within the aquatic system. Samples of aquatic
Stoichiometry of aerobic mineralization (O/C) of aquatic macrophytes leachate from a tropical lagoon (São Paulo –Brazil)
TLDR
In the early phase of mineralization the O/C rates increased before reaching a maximum, after which they tended to decrease, which is believed to be associated with the chemical composition of the leachates, with their transformations and alterations of metabolic pathways involved in the mineralization.
Decomposition of dissolved organic matter released by an isolate of Microcystis aeruginosa and morphological profile of the associated bacterial community.
TLDR
Both fractions of DOM were consumed rapidly, corroborating the hypothesis that DOM is readily available in the environment and suggesting that the bacterial community in the inocula readily uses the labile part of the DOM, until this community is able to metabolise efficiently the remaining of DOM not degraded in the first moment.
