Further, intermediate levels of nutrients under low light attenuation by TSS and macrophytes potentially supported higher phytoplankton biomass, pelagic GPP and the subsequent net autotrophy in waters of St 30 comparing with stations more recently dredged (St 02 and St 15).
Hence, evaluation of the effects of reduced salinity on autotrophy and on the zooxanthellae is needed to understand more fully the adaptation mechanism of giant clams under longer exposure to reduced-salinity conditions.
1994) suggested that inorganic nutrient inputs associated with human perturbation have driven the global ocean towards autotrophy.
14]C bicarbonate (Schiemer et al, 1990) and the presence of RuBisCo enzymatic activity indicate Laxus ectosymbiont autotrophy (Polz et al, 1992).
The type of vegetation cover and rainfall can also determine conditions of autotrophy or heterotrophy in streams, having a strong effect upon the stream food web structure and dynamics, as shown by Uieda and Motta (2007) for some tropical streams.
contorfum population from an arctic cold seep at the Haakon Mosby Mud Volcano have characteristic functional genes for autotrophy and sulfur oxidation (Losekann et al.
In general, the pattern of net metabolism observed in these systems may be strongly dependent on the delivery of organic matter or inorganic nutrient into the system, which may favor either heterotrophy or autotrophy, respectively.
in symbiotic status and the distinction in reliance on phototrophy versus autotrophy allow us to further explore detailed aspects of how mutualisms influence ecological patterns and evolutionary trajectories.
system autotrophy or heterotrophy derived from scraper or shredder abundance or biomass).
16 seems to be a truly general food-web model, for it describes all types of trophic relationships including autotrophy and heterotrophy, monophagy, polyphagy, omnivory, cannibalism and mutual predation, intra- and inter-specific competition, and single- to multiple-species population interactions.
