The Red Sea was witness to important events during human history, including the first long steps in a trade network (the spice route) that would drive maritime technology and shape geopolitical fortunes for thousands of years. Punt was a pivotal earl

Stable carbon and oxygen isotope ratios in tooth enamel and bone hydroxyapatite are used to answer a variety of ecological questions. Researchers employ chemical treatments to reduce contaminants that may interfere with the isotope ratios in hydroxya

Calcium stable isotope ratios are hypothesized to vary as a function of trophic level. This premise raises the possibility of using calcium stable isotope ratios to study the dietary behaviors of fossil taxa and to test competing hypotheses on the ad

Ecologists are increasingly using stable isotope analysis to inform questions about variation in resource and habitat use from the individual to community level. In this study we investigate data sets from 2 California sea otter (Enhydra lutris nerei

Alligators and crocodiles differ in their physiological capacity to live in saline waters. Crocodiles can tolerate high-salinity water, at least for limited timeframes, whereas alligators and their close relatives cannot. Experiments have placed diff

Isotopic studies of palaeoecological and ecological questions often use bone collagen or bioapatite as substrates, but rarely both. Substantial new information can be gained from the incorporation of isotopic values from both the organic and inorgani

Identification ofcervid material from these sites was likely made on geographic bases,rather than on unique morphological characters.As is true at many other early to middle Pliocene localities in NorthAmerica, cervid material is rare at Hagerman Fos
