ABSTRACT Based on the assumptions that human food is available for dogs and isotope diet–tissue differences are similar in dogs and humans, the ‘canine surrogacy approach’ (CSA) has been used to infer patterns of ancient populations. The goal of this study was to test the CSA in urban (Brasília and Piracicaba) and in rural (Ubatuba and Maraã) areas. The hair C and N isotope ratios of modern dogs were compared with those of human fingernails from different regions of Brazil. Our CSA results… Expand

Identifying the composition of commercial Brazilian cat food with stable isotopes of carbon and nitrogen
It is concluded that chicken and pork seem to be the dominant ingredients in most of the samples, with larger proportions in wet cat food, which raises the question whether this should be mentioned on package labels. Expand
Mapping carbon and nitrogen isotopic composition of fingernails to demonstrate a rural-urban nutrition transition in the Center-West, Northeast, and Amazon regions of Brazil.
Investigating diet patterns among rural and urban populations of the Center-West, Northeast, and Amazon regions of Brazil through the carbon and nitrogen isotopic composition of fingernails suggested that "market integration" does not affect everyone equally in each community. Expand


Dog-human dietary relationships in Yup'ik western Alaska: The stable isotope and zooarchaeological evidence from pre-contact Nunalleq
Abstract Historically and ethnographically dogs have been an important resource for Arctic and subarctic societies — providing protection, fur and meat, as well as aiding hunting and transportation.Expand
Burying Dogs in Ancient Cis-Baikal, Siberia: Temporal Trends and Relationships with Human Diet and Subsistence Practices
Direct radiocarbon dating of a suite of the Lake Baikal region’s dog remains indicates that these animals were given burial only during periods in which human burials were common, and stable carbon and nitrogen isotope data indicate that dogs were only buried where and when human diets were relatively rich in aquatic foods.

The Utility of Dog Bone (Canis Familiaris) In Stable Isotope Studies for Investigating the Presence of Prehistoric Maize (Zea Mays Ssp. Mays): A Preliminary Study
This preliminary study investigates an alternative method to exploring and understanding the presence of maize (Zea mays ssp. mays) in prehistoric human settlement areas using stable isotope ratiosExpand
Dogs as Analogs in Stable Isotope-Based Human Paleodietary Reconstructions: A Review and Considerations for Future Use
This paper shows that CSA applications are essentially analogical inferences which can be divided into two groups that provide specific types of information and may require different levels of substantiation and a framework of three categories of factors is outlined to aid in establishing positive, negative, and neutral elements of comparison of dog and human diets.

Stable isotope analysis of dog, fox, and human diets at a Late Holocene Chumash village (CA-SRI-2) on Santa Rosa Island, California
Carbon isotopic signatures indicate that Native Americans and their dogs at CA-SRI-2 subsisted almost exclusively on marine resources, while the island fox ate primarily terrestrial foods, similar to the diets observed in modern fox populations. Expand
Diet adaptation in dog reflects spread of prehistoric agriculture
It is concluded that the diet change in dog diet may not have been associated with initial domestication but rather the subsequent development and spread of agriculture to most, but not all regions of the globe. Expand
δ13C-Values of dog bones reveal the nature of changes in man's food resources at the Mesolithic-Neolithic transition, Denmark
Abstract Carbon isotope ratios of bone collagen yield important information on the nature of the main diet utilized by man. Non-marine food is characterized by significantly lower δ13C-values thanExpand

Modern human hair data from the triple stable isotope (delta(13)C, delta(15)N and delta(34)S) provided enough information to confirm the dietary status and origin of the individual subjects. Expand
