Zooplankton and the Ocean Carbon Cycle. (2017, background): “For example, Saba et al. (2011) found that excretion and sloppy feeding constituted 80% and 20% of total DOC released, respectively, whereas any DOC release from fecal pellet leaching was undetectable.”
Increased carbon dioxide availability alters phytoplankton stoichiometry and affects carbon cycling and growth of a marine planktonic herbivore (2012, background): “Carbon excreted through respiration as CO2 is essentially lost to the system, in which it is already in high supply, while carbon excreted as DOC is potentially available to heterotrophic microorganisms, such as bacteria (Saba et al. 2011).”
Marine biodiversity and ecosystem function relationships: The potential for practical monitoring applications (2015, unknown): “A signi ﬁ cant amount of dissolved organic matter (DOM) can also be released through inef ﬁ cient feeding, excretion and defaecation (Saba et al., 2011), which suggests that herbivory might be an important source of bacterial substrate (Lampert, 1978; Gude, 1988).”
Formation of Chromophoric Dissolved Organic Matter by Bacterial Degradation of Phytoplankton-Derived Aggregates (2018, background): “Additional phytoplanktonic DOM is released through viral infection, sloppy feeding by predators such as zooplankton, and cell death, with zooplankton contributing their own DOM through excretion of organic matter and fecal pellets (Urban-Rich et al., 2006; Steinberg et al., 2008; Saba et al., 2011).”
Carbon fluxes and pelagic ecosystem dynamics near two western Antarctic Peninsula Adélie penguin colonies: an inverse model approach (2013, background): “Thus, when the phytoplankton assemblage is dominated by the larger size fraction, sloppy feeding by krill is an additional source of DOC (up to 3% of the grazed phytoplankton carbon, 12% by excretion; see Saba et al. 2011 for copepods).”
Nitrification and ammonium dynamics in Taihu Lake, China: seasonal competition for ammonium between nitrifiers and cyanobacteria (2017, background): “The uptake rate is considered a potential rate, which includes nitrification, assimilation, and other consumption processes; regeneration is an actual rate that encompasses remineralization, decomposition of dead organic matter, heterotrophic excretion, respiration, biodegradation, and sloppy feedin”
