A niche for isotopic ecology
- S. Newsome, C. M. Rio, S. Bearhop, D. Phillips
- Biology
- 1 October 2007
Fifty years ago, GE Hutchinson defined the ecological niche as a hypervolume in n-dimensional space with environmental variables as axes. Ecologists have recently developed renewed interest in the… Expand
Using stable isotope biogeochemistry to study marine mammal ecology
- S. Newsome, M. Clementz, P. Koch
- Biology
- 1 July 2010
Stable isotope analysis (SIA) has emerged as a common tool in ecology and has proven especially useful in the study of animal diet, habitat use, movement, and physiology. SIA has been vigorously… Expand
Using Isoscapes to Trace the Movements and Foraging Behavior of Top Predators in Oceanic Ecosystems
- B. Graham, P. Koch, S. Newsome, K. McMahon, D. Aurioles
- Environmental Science
- 2010
The stable isotope composition of animal tissues can provide intrinsic tags to study the foraging and migratory ecology of predators in the open ocean. Chapter 13 (this volume) demonstrated that by… Expand
Agricultural origins and the isotopic identity of domestication in northern China
- L. Barton, S. Newsome, Fahu Chen, H. Wang, T. Guilderson, R. Bettinger
- Geography, Medicine
- Proceedings of the National Academy of Sciences
- 7 April 2009
Stable isotope biochemistry (δ13C and δ15N) and radiocarbon dating of ancient human and animal bone document 2 distinct phases of plant and animal domestication at the Dadiwan site in northwest… Expand
Combining sources in stable isotope mixing models: alternative methods
- D. Phillips, S. Newsome, J. Gregg
- Biology, Medicine
- Oecologia
- 16 February 2005
Stable isotope mixing models are often used to quantify source contributions to a mixture. Examples include pollution source identification; trophic web studies; analysis of water sources for soils,… Expand
USING CARBON AND NITROGEN ISOTOPE VALUES TO INVESTIGATE MATERNAL STRATEGIES IN NORTHEAST PACIFIC OTARIIDS
- S. Newsome, P. Koch, Mike Etnier, D. Aurioles-Gamboa
- Biology
- 1 July 2006
We examine the utility of stable carbon and nitrogen isotope variations to characterize the length of the nursing/lactation period and age at weaning for two northern Pacific otariid species, the… Expand
Using stable isotopes to investigate individual diet specialization in California sea otters (Enhydra lutris nereis).
- S. Newsome, M. T. Tinker, +5 authors J. Estes
- Biology, Medicine
- Ecology
- 1 April 2009
Differences in diet composition among conspecifics (dietary specialization) have been documented across a broad range of taxonomic groups and habitats, and such variation at the individual level is… Expand
Pleistocene to recent dietary shifts in California condors.
- C. Chamberlain, J. Waldbauer, +7 authors R. Risebrough
- Biology, Medicine
- Proceedings of the National Academy of Sciences…
- 15 November 2005
We used carbon and nitrogen isotopes to investigate changes in the diet of California condors from the Pleistocene to the recent. During the Pleistocene, condors from California fed on both… Expand
Stable isotopes evaluate exploitation of anthropogenic foods by the endangered San Joaquin kit fox (Vulpes macrotis mutica)
- S. Newsome, K. Ralls, C. Job, M. Fogel, B. Cypher
- Geography
- 16 December 2010
Abstract The unprecedented rate of urbanization over the past several decades is a major concern for conservation globally and has given rise to the multidisciplinary field of urban ecology. This… Expand
Retrospective characterization of ontogenetic shifts in killer whale diets via δ 13 C and δ 15 N analysis of teeth
- S. Newsome, M. Etnier, D. Monson, M. Fogel
- Biology
- 13 January 2009
Metabolically inert, accretionary structures such as the dentin growth layers in teeth provide a life history record of individual diet with near-annual resolution. We constructed onto- genetic δ 13… Expand
