A feather hydrogen (δ2H) isoscape for Brazil

open access: yesPLoS ONE, 2022
Spatial patterns of stable isotopes in animal tissues or “isoscapes” can be used to investigate animal origins in a range of ecological and forensic investigations.

A strontium isoscape of southwestern Australia and progress toward a national strontium isoscape [PDF]

open access: yesEarth System Science Data
Strontium isotopes (87Sr/86Sr) are widely used tracers in the geosciences. Here we exploit an opportunity to determine 87Sr/86Sr ratios on archived fluvial sediment samples from the low-density National Geochemical Survey of Australia (NGSA). The present

A Bayesian classification model to reconstruct lifetime movement patterns of riverine fish using environmental tracers

open access: yesMethods in Ecology and Evolution
Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes.

A bioavailable strontium isoscape of Australia [PDF]

open access: yesEarth System Science Data
Strontium isotope ratios (87Sr/86Sr) at the Earth's surface offer powerful tools for geological, environmental, and archaeological applications. In minerals and biological materials, 87Sr/86Sr reflects the isoztopic composition of the local bedrock and ...

Emu (Dromaius novaehollandiae) diet is driven by the gradient of C3 and C4 plant availability

open access: yesEcosphere
Intraspecific variation in diet is often influenced by geographic location, resource availability, trophic position, or foraging specialization and can result in environmental changes exerting heterogeneous effects across the species' distribution ...

An insect isoscape of UK and Ireland [PDF]

open access: yesRapid Communications in Mass Spectrometry, 2021
Rationale The study of insect migration is problematic due to the small size of insects. Stable isotope analysis can be used to elucidate movement, either by geographic assignment of location of a species, or by simply distinguishing migrant from resident populations.

Toward a Deuterium Feather Isoscape for Sub-Saharan Africa: Progress, Challenges and the Path Ahead. [PDF]

open access: yesPLoS ONE, 2015
A key challenge to the application of continent-wide feather isoscapes for geographic assignment of migrant birds is the lack of ground-truthed samples. This is especially true for long-distance Palearctic-Afrotropical migrants.

Regional scale high resolution δ18O prediction in precipitation using MODIS EVI. [PDF]

open access: yesPLoS ONE, 2012
The natural variation in stable water isotope ratio data, also known as water isoscape, is a spatiotemporal fingerprint and a powerful natural tracer that has been widely applied in disciplines as diverse as hydrology, paleoclimatology, ecology and ...

Isoscapes: a new dimension in community ecology [PDF]

open access: yesTree Physiology, 2016
[Extract] The utility of stable isotopes in interpreting and recording aspects of environmental science, biogeochemistry, ecology and organismal physiology has long been established (Peterson and Fry 1987, Dawson et al. 2002). Examples range from the reconstruction of prehistoric human diets (Schoeninger et al.

Forensic isoscapes based on intra-individual temporal variation of δ18O and 206Pb/207Pb in human teeth

open access: yesForensic Sciences Research, 2021
Isotopic signatures used in the georeferencing of human remains are largely fixed by spatially distinct geologic and environmental processes. However, location-dependent temporal changes in these isotope ratios should also be considered when determining ...
