“…6, 8, and 31). Compared with modern taxa with a similar sample size, the range and SD for K. platyops is broad and large, respectively (14,32). The δ 13 C values for the 18 K. platyops individuals are normally distributed, One specimen has been assigned to Homo sp.…”

“…10 kg (e.g., dik-dik and other neotragines) tend to be browsers and have C 3 -based diets (14,32), whereas large herbivores can have diets that are C 3 -based (browsers such as most tragelephines, black rhinos, and giraffes), C 4 -based (grazers such as warthogs, zebra, alcelaphines, reducines, and bovines), or mixed (e.g., impala, and some gazelles). Thus, the size of prey may be important in considering possible secondary diet C 3 or C 4 resources.…”

“…Stable isotope ratios of 13 C/ 12 C are ideally suited to test this hypothesis because of the difference in isotope ratios between C 3 plants (most dicots) and C 4 plants (grasses and sedges, both of which are monocots) in the tropics; the dietary distinction between C 3 and C 4 plant-derived foods is preserved in the fossil record of Africa for most of the past 10 Ma (14,15). The δ 13 C values of tooth enamel from modern and fossil browsers are about −12‰ in open forests through grasslands, whereas grazers have δ 13 C values near 2‰, and mixed feeders have intermediate values (16)(17)(18)(19). We note that mammals from closed canopy forests are even more depleted in 13 C than those mammals from open forests (20).…”

“…Yet that review was hindered by the nature of the available literature which, because of the variety of methodologies employed by researchers in the field, and the fact that most published studies are isolated in space and time (Owen-Smith 1988, 1997, comprised data that are not necessarily comparable. More recently, stable carbon isotope studies (yielding data that are more comparable across geographical and temporal boundaries) revealed differences for several species not only when compared with predictions from the literature, but also between southern and East African populations (Cerling et al 2003;Sponheimer et al 2003a;Codron et al 2007a). These findings imply that diets of many species are habitat-specific, and that global averages -as often used in comparative evolutionary and ecological studies (Clauss 2008;Codron & Clauss 2010) -may be of limited value.…”

“…Research on diet composition and diet quality has revealed that coexistence is achieved primarily through resource partitioning, in particular the separation of dietary niches along a browser/grazer continuum, with three guilds typically recognized: browsers, grazers and mixed-feeders (Hofmann & Stewart 1972;Jarman 1974;Owen-Smith 1997;du Toit 2003;Clauss 2008). Recent reviews and evidence from stable carbon isotopes have, however, reached dissimilar conclusions regarding the diets of many species, and differ in their respective interpretations of the heuristic value of the browser/grazer classification scheme (Gagnon & Chew 2000;Sponheimer et al 2003a;Cerling et al 2003;Codron et al 2007a). One source of this confusion is the vast and often contradictory literature on bovid feeding ecology.…”
