Carbon isotopic evidence for different feeding patterns in two hyrax species occupying the same habitat.

چکیده
The carbon-13/carbon-12 ratios of the carbonate and collagen fractions of bone of the sympatric hyrax species Procavia johnstoni and Heterohyrax brucei indicate that the former obtains most of its diet by grazing while the latter is primarily a browser. The carbon-13/carbon-12 ratios of these fractions in fossil bone will record information about diet if they have not been altered during diagenesis.

Stable isotope canopy effects for sympatric monkeys at Taı̈ Forest, Côte d’Ivoire
This study tests the hypothesis that vertical habitat preferences of different monkey species inhabiting closed canopy rainforest are reflected in oxygen isotopes. We sampled bone from seven sympatric cercopithecid species in the Taı̈ forest, Côte d’Ivoire, where long-term study has established taxonspecific patterns of habitat use and diet. Modern rib samples (n 1⁄4 34) were examined for oxygen...

متن کاملIsotopic reconstructions of habitat change surrounding the extinction of Sivapithecus, a Miocene hominoid, in the Siwalik Group of Pakistan
This research presents an isotopic study of a wide range of mammalian taxa from the Miocene Siwalik Group of Pakistan, with a focus on two time intervals—9.3–9.2 Ma, when the hominoid Sivapithecus was present, and 8.1–8.0 Ma, shortly after Sivapithecus became extinct. The purpose of this investigation is to reconstruct the vegetation mosaic at both time levels in order to determine what Sivapit...
متن کاملIsotopic incorporation rates for shark tissues from a long-term captive feeding study.
Stable isotope analysis has provided insight into the dietary and habitat patterns of many birds, mammals and teleost fish. A crucial biological parameter to interpret field stable isotope data is tissue incorporation rate, which has not been well studied in large ectotherms. We report the incorporation of carbon and nitrogen into the tissues of leopard sharks (Triakis semifasciata). Because sh...
متن کاملA phylogenetic test for adaptive convergence in rock-dwelling lizards.
Phenotypic similarity of species occupying similar habitats has long been taken as strong evidence of adaptation, but this approach implicitly assumes that similarity is evolutionarily derived. However, even derived similarities may not represent convergent adaptation if the similarities did not evolve as a result of the same selection pressures; an alternative possibility is that the similar f...
