Mixotrophy in microorganisms: Ecological and cytophysiological aspects
Journal of Evolutionary Biochemistry and Physiology, 2013Mixotrophy is the ability to combine autotrophic and heterotrophic modes of nutrition. It is widely spread in various microorganisms, particularly in such important plankton groups as dinoflagellates and cyanobacteria. Mixotrophy has a significant impact on our comprehension of the matter and energy flows in marine ecosystems, and therefore, it is an ...

The Modelling of Mixotrophy in the Oligotrophic Atlantic [PDF]
, 2012 In the oligotrophic Atlantic Ocean small algae are the dominant fixers of inorganic carbon. In situ experiments have shown that a large proportion of these algae are mixotrophs - eating bacteria (bacterivory) as well as obtaining energy from sunlight.

Mixotrophy in Freshwater Foodwebs
, 2016 Environmental heterogeneity in both space and time has significant repercussions for community structure and ecosystem processes. Dimictic lakes provide examples of vertically structured ecosystems that oscillate between stable and mixed thermal layers on a seasonal basis.

Mixotrophy in the Marine Plankton
Annual Review of Marine Science, 2017Mixotrophs are important components of the bacterioplankton, phytoplankton, microzooplankton, and (sometimes) zooplankton in coastal and oceanic waters. Bacterivory among the phytoplankton may be important for alleviating inorganic nutrient stress and may increase primary production in oligotrophic waters.

Mixotrophy is the occurrence of phagotrophy and phototrophy in the same organism. In ciliates the intracellular phototroph can be unicellular green algae (zoochlorellae), dinoflagellates (zooxanthellae), cryptomonads or sequestered chloroplasts from ingested algae.

Acquired Phototrophy as an Evolutionary Path to Mixotrophy
The American Naturalist, 2023AbstractAcquired photosynthesis transforms genotypically heterotrophic lineages into autotrophs. Transient acquisitions of eukaryotic chloroplasts may provide key evolutionary insight into the endosymbiosis process-the hypothesized mechanism by which eukaryotic cells obtained new functions via organelle retention. Here, we use an eco-evolutionary model

Introducing mixotrophy into a biogeochemical model describing an eutrophied coastal ecosystem: The Southern North Sea [PDF]
Progress in Oceanography, 2017 Most biogeochemical/ecological models divide planktonic protists between phototrophs (phytoplankton) and heterotrophs (zooplankton). However, a large number of planktonic protists are able to combine several mechanisms of carbon and nutrient acquisition.

Abstract Mixotrophy, the uptake of particulate and dissolved organic carbon by photosynthetic algae, is widespread in haptophyte flagellates, in particular in the genus Chrysochromulina. Some species of Chrysochromulina have been shown to discriminate between particles on the basis of particle size and composition.

Mixotrophy among Dinoflagellates1
Journal of Eukaryotic Microbiology, 1999Mixotrophy, used herein for the combination of phototrophy and phagotrophy, is widespread among dinoflagellates. It occurs among most, perhaps all, of the extant orders, including the Prorocentrales, Dinophysiales. Gymnodiniales, Noctilucales, Gonyaulacales, Peridiniales, Blastodiniales. Phytodiniales, and Dinamoebales.

Nanoplankton mixotrophy in the eastern equatorial Pacific
Deep Sea Research Part II: Topical Studies in Oceanography, 2011Heterotrophic bacteria, cyanobacteria, and picoeukaryotic algae dominate the plankton community of high nutrient-low chlorophyll (HNLC) areas of the eastern equatorial Pacific (EEP). While grazing on these picoplankton is often attributed to aplastidic zooflagellates, mixotrophic nanoflagellates (phagotrophic phototrophs) may also exert a large grazing
