Mapping the origin of faunal assemblages using strontium isotopes

  title={Mapping the origin of faunal assemblages using strontium isotopes},
  author={Stephen Porder and Adina Paytan and Elizabeth A. Hadly},
Abstract One of the greatest challenges in using faunal assemblages to make ecological or paleoecological interpretations is determining the spatial scale over which such analyses are applicable. As a result, it has been difficult to use these assemblages to test hypotheses about spatial and temporal variability in populations. Here we show that it is possible to use strontium (Sr) isotopes from bones and vegetation to statistically constrain the area sampled in two Holocene predator… 

Determining landscape use of Holocene mammals using strontium isotopes

Assessing landscape use of mammals by analyzing strontium (Sr) isotope signatures found in mammalian hard tissues representing a 3,000-year record indicates that medium- and large-sized species use larger percentages of the landscape than do species of small body size.

Strontium isotope analyses of large herbivore habitat use in the Cape Fynbos region of South Africa

It is suggested that Sr isotope analysis is a valuable additional tool for exploring large mammal foraging behaviour on habitats associated with contrasting and less complex geology.

The Concept of Isotopic Landscapes: Modern Ecogeochemistry versus Bioarchaeology

The term “isotopic landscape” or “isoscape” is used to indicate a map depicting isotopic variation in the environment. The spatial distribution of isotopic ratios in environmental samples is an

Isotope domain mapping of 87Sr/86Sr biosphere variation on the Isle of Skye, Scotland

Abstract: The potential of 87Sr/86Sr isotope composition for tracking and determining the origin of material, whether it is humans, animals, water or wine can be fully realized only if high-quality

Spatial variations in biosphere 87Sr/86Sr in Britain

Abstract: Strontium isotopes are a powerful tool for investigating the geographical origins of people and animals but assignment of provenance requires reference maps and databases. This paper

Strontium isotopes (87Sr/86Sr) in terrestrial ecological and palaeoecological research: empirical efforts and recent advances in continental‐scale models

The local water model provides a readily available source of background data for predicting 87Sr/86Sr for biologically relevant materials in places where empirical data are lacking and the availability of increasingly high‐quality modelled Sr data will dramatically expand the accessibility of this geochemical tool to ecological applications.

Ghosts of Yellowstone: Multi-Decadal Histories of Wildlife Populations Captured by Bones on a Modern Landscape

This work expands the environmental sampling of large-mammal death assemblages into a temperate biome and explores more demanding assessments of ecological fidelity by testing their capacity to record past population fluctuations of individual species in the well-studied ungulate community of Yellowstone National Park (Yellowstone).

Stasis and change in Holocene small mammal diversity during a period of aridification in southeastern Utah

Biological conservation depends on understanding and disentangling the effects of decadal- to centennial-scale dynamics from the millennial-scale dynamics documented in the fossil record. The



Taphonomy and paleobiology

Abstract Taphonomy plays diverse roles in paleobiology. These include assessing sample quality relevant to ecologic, biogeographic, and evolutionary questions, diagnosing the roles of various

An exceptionally rich paleontological site containing thousands of mammalian fossils and well-dated with 18 radiocarbon samples provides evidence of late-Holocene ecological response to climatic

Strontium isotopes reveal distant sources of architectural timber in Chaco Canyon, New Mexico

The use of trees from both the Chuska and San Mateo mountains, but not from the San Pedro Mountains, as early as A.D. 974 suggests that selection of timber sources was driven more by regional socioeconomic ties than by a simple model of resource depletion with distance and time.

A genetic record of population isolation in pocket gophers during Holocene climatic change.

The results demonstrate that small mammal populations can experience the long-term isolation assumed by many theoretical models of microevolutionary change.

Tracking mammoths and mastodons: Reconstruction of migratory behavior using strontium isotope ratios

Variations in the strontium isotope ratio ( 87 Sr/ 86 Sr) of tooth enamel are used to examine the migration patterns of late Pleistocene mammoths and mastodons from Florida. An animal’s 87 Sr/ 86 Sr

Evolutionary and ecological response of pocket gophers (Thomomys talpoides) to late‐Holocene climatic change

  • 1997
Late-Holocene evolutionary and ecological response of pocket gophers and other species to climatic change is documented by mammalian fossils from Lamar Cave, a palaeontological site in northern Yellowstone National Park, and two craniodental characters for the northern pocket gopher are investigated.

Isotopic Tracking of Change in Diet and Habitat Use in African Elephants

The high isotopic variability produced by behavioral and ecological shifts, if it is representative of other East African elephant populations, may complicate the use of isotopes as indicators of the source region of ivory.

Lead and strontium isotopes in rocks of the Absaroka volcanic field, Wyoming

The Absaroka volcanic field is comprised of predominant andesitic volcaniclastic rocks and less abundant potassium-rich mafic lavas (shoshonites and absarokites). Strontium and lead isotopic
