The impossibility of such a creation sequence was argued in my book on the premise that "planets can only come into existence given the presence of a Sun" and from that, it could be egested
into space and not vice-versa.
If sharks were indeed the scavenging animals, it is likely that the tags were regurgitated, rather than egested
through the alimentary canal, whereupon the PSAT floated to the surface and was able to transmit the archived data.
They argue that pellet content may not reflect prey base particularly when potential prey differ in size because when larger-size prey are consumed they must be egested
before new prey can be ingested.
We estimated resampling errors related to the variability in digestion of egested
structures by repeatedly selecting n structures, at random, with replacement from the original sample set of n egested
Significant costs of particle sorting, digestion, and absorption, evidenced as metabolically derived material egested
and assayed within feces, were greatest in species with higher saturated capacities for the ingestion of remaining organics.
Consumption of seston portions by shellfish means that some suspended solids that would otherwise drift by fish cages now have the potential for redirection to the benthos as indigestible seston components, egested
in shellfish feces.
Desirable particles are ingested and further processed, and either expelled during the second sorting stage as intestinal feces or processed by the digestive gland and later egested
as true mussel feces (Dame 1993, Giles & Pilditch 2004, Callier et al.
Clearance rate (measured in liters per gram per hour) was calculated as milligrams of inorganic matter egested
both as feces and pseudofeces per hour divided by milligrams of inorganic matter available per liter of seawater (Hawkins et al.
l]: chl a was unchanged in the feces and pseudofeces relative to the algal diet, indicating that cells of Isochrysis were excreted or egested
in the same proportion as the diet (Fig.
Selective attainment to a steady state concentration of individual acids, with excess dietary acids being egested
has been suggested for the blue mussel Mytilus edulis (Whyte et al.
