Gross anatomy of the stomach of the dorcas gazelle (Gazella Dorcas, Linnaeus, 1758)


Jerbi, Hassen; Bayoudh, Mohamed; Clauss, Marcus; Pérez, William (2016). Gross anatomy of the stomach of the dorcas gazelle (Gazella Dorcas, Linnaeus, 1758). International Journal of Morphology, 34(4):1266-1270.

Abstract

The macroscopic anatomy of the stomach in four adult dorcas gazelle was described. Four adult, two male and two female dorcas gazelle (Gazella dorcas) of the Frigya Zoological Park, Enfidha, Tunisie, were used in this study. The ruminal papillae were distributed unequally in the rumen, and were larger and more abundant within the atrium and in the two saccus cecus. The papillae were absent in dorsal part of the dorsal sac. The ruminal pillars had no papillae. The cellulae reticuli were divided and contained secondary and tertiary crests. The curvatura omasi measured 12.1±0.1 cm. A comparison with literature data for sand gazelles (Gazella subgutturosa marica) emphasises that differences between closely related species that fill similar niches cannot be expected to follow a clear pattern, but yield an inhomogenous picture, with some measurements more tending towards a specific feeding type in the one, and some other measurements tending more towards that feeding type in the other species.We concluded that the stomach morphology of the dorcas gazelle indicates the‘cattle-type’ morphophysiology representative for intermediate feeders.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
