The Spatial Distribution of Terrestrial Stable Carbon Isotopes in North America, and the Impacts of Spatial and Temporal Resolution on Static Ecological Models
… terrestrial stable carbon isotopic landscapes (isoscapes). I model the distribution of leaf stable carbon isotope composition (delta<sup>13</sup>C) for the continent of North America at multiple temporal and spatial resolutions. I generate each delta<sup>13</sup>C isoscape variation by first …

Flight feather moult patterns and stable isotope analysis in the Woodland Kingfisher
… South African population lies within the same isoscape band as that of Ugandan birds. δ 15N values, which indicate trophic levels, were similar for all the birds, suggesting that Woodland Kingfishers in Ghana, South Africa and Uganda forage on similar prey. The observations of colourringed …

The movement ecology of common bream Abramis brama in a highly connected wetland using acoustic telemetry.
… The efficacy of single versus dual-isotope isoscapes in predicting the foraging locations of roach Rutilus rutilus was compared, with the dual-isoscape approach emerging as the most efficient. Dual-isoscapes were then applied to predicting the movement distances of individual bream in …

Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
… diet, providing a δ13C record of the baseline isoscape. We explored the potential for geochemical signatures in otoliths of snapper to act as natural tags of residency in seagrass beds, mangroves and coral reefs in the Red Sea, Caribbean Sea and Eastern Pacific Ocean. The δ13C values of otolith …

Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
… diet, providing a 513C record of the baseline isoscape. We explored the potential for geochemical signatures in otoliths of snapper to act as natural tags of residency in seagrass beds, mangroves and coral reefs in the Red Sea, Caribbean Sea and Eastern Pacific Ocean. The 13C values of otolith …

Advancements in Isotopic Geolocation Tools for Insect Migration Research
… a spatial model of isotopic variation (i.e., an isoscape) using random forest regression. I then combine hydrogen isotope values (δ²H) and ⁸⁷Sr/⁸⁶Sr into a dual assignment framework to estimate the natal origins of a single generation of monarch butterflies in eastern North America. I demonstrate …
