Comparative morphology of the digestive system of 19 species of Southern African myomorph rodents in relation to diet and evolution
Abstract
Trends in digestive system-morphology have been examined in 19 species of Southern African myomorph rodents. Structure was related to function, diet, and evolution. Characters related to an ancestral proteinaceous diet, and specialized characters associated with herbivory, were recognized. All stomachs were of the unilocular hemiglandular type with increasing degrees of cornification of the corpus, although the stomach of Saccostomus compestris approached the bilocular discoglandular condition. Those of Thallomys paedulcus and Mystromys albicaudatus were highly modified in containing numerous papillae in the corpus, possibly associated with gastric fermentation. The most complex caeca, of the herbivorous Otomyids, possessed numerous haustra and internal papillae probably associated with caecal microbial fermentation.

This pattern (voluminous, haustrated cecum) is recognised as a common feature in many rodents.
“This pattern is recognised as a common feature in many rodents (Kotze et al., 2010;Perrin and Curtis 1980;Perez et al., 2008).”

The cecum of lagomorphs and rodents has been divided into three distinct anatomical segments: ampulla ceci, corpus ceci and apex ceci.
“The cecum of lagomorphs and rodents has been divided into three distinct anatomical segments: ampulla ceci (the base of the cecum), corpus ceci and apex ceci (Perrin and Curtis 1980;Snipes 1981Snipes , 1982a,b;,b;Perez 2005Perez , 2007Perez , 2008)).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
