...: Hemiauchenia paradoxa , Lama guanicoe , and Vicugna vicugna . The analysis of carbon and oxygen stable isotope ratios in bioapatite provides insight into the paleobiology of nonliving animals and the environment they used to inhabit. We applied this tool to investigate the diet of camelids from two geological...

..., but aspects of its biology remain unclear. In this study, we used multivariate dental topography analysis (DTA) to reconstruct the diet of N. magdalenensis by quantitatively comparing measures of molar complexity with those of 25 modern noctilionoid species representing all major dietary habits in bats. We...

..., also known as ‘wood-pasture’ ( Vera 2000 ; Kirby 2004 ). Conservation grazing by large herbivores is increasingly used as a management tool in temperate woodlands ( Humphrey et al. 1998 ; Hodder et al. 2005 ). Secondly, megaherbivores played an important role in the diet of Late Pleistocene...

... ), moose ( Alces alces ), and caribou ( Rangifer tarandus ). Paired antler–bone δ 13 C Coll and δ 15 N Coll from the same individual were used to identify differences between summer and annual diet and ecology. Intra-antler isotopic variability from serially sampled antlers was used to examine seasonal...

Additionally, it is clear that Paleogene penguins occupy...

... for local space (Zhuravlev et al. 2015 ), we here test the hypothesis that food was a limiting resource that drove competition in archaeocyathan communities. What archaeocyaths fed on is unknown, but is usually assumed to be bacteria, as these are important to the diet of extant sponges (Kruse et al. 1995...

... such material. Herein, we regard coleoids with an opportunistic diet as the most likely producers of the aptychi-bearing regurgitalites. This is based on finds of aptychi in the stomachs of the two coleoids Plesioteuthis and Trachyteuthis. They were likely fast, highly manoeuvrable swimmers. Both share a strong...
