Strontium isoscapes for provenance, mobility and migration: the way forward. [PDF]

R Soc Open Sci
Strontium isotopes ( 87 Sr/ 86 Sr) are increasingly used as a provenance tool in multiple disciplines. Application to biological materials requires knowledge of the variation in bioavailable 87 Sr/

Dual‐isotope isoscapes for predicting the scale of fish movements in lowland rivers

Ecosphere, 2021
Assessments of patterns of animal movements are important for understanding their spatial ecology. Geostatistical models of stable isotope (SI) landscapes (isoscapes) provide a complementary tool to telemetry for assessing and predicting animal movements,

Southern Sardinia Isoscape as GEOTIFF.

, 2023
Since prehistoric times, the island of Sardinia—in the western Mediterranean—has played a leading role in the dynamics of human population and mobility, in the circulation of raw materials and artefacts, idioms and customs, of technologies and ideas that

Identifying nesting grounds for juvenile migratory birds with dual isotope: an initial test using North American raptors

Ecosphere, 2021
Understanding seasonal mobility, population connectivity, and site fidelity is critical for managing and preserving migratory species. We investigated the potential of coupling strontium (87Sr/86Sr) and hydrogen (δ2H) isotopes in feathers for ...

Isotopic Tracers Suggest Limited Trans-Oceanic Movements and Regional Residency in North Pacific Blue Sharks (Prionace glauca)

Frontiers in Marine Science, 2021
Blue sharks (Prionace glauca) are globally distributed, large-bodied pelagic sharks that make extensive migrations throughout their range. In the North Pacific, mark-recapture studies have shown trans-Pacific migrations, but knowledge gaps in migration ...

Reconstructing continental‐scale variation in soil δ15N: a machine learning approach in South America

Ecosphere, 2020
Soil nitrogen isotope composition (δ15N) is an essential tool for investigating ecosystem nitrogen balances, plant–microbe interactions, ecological niches, animal migration, food origins, and forensics. The advancement of these applications is limited by
