| contents | The geological imprint of neodymium isotopes in marine gastropods. Doubleday, Zoe Chung, Ming-Tsung Payne, Justin Martino, Jasmin Tanaka, Kentaro Tazoe, Hirofumi Tristao Rezio, Arieli Wu, Po-Chao Huang, Kuo-Fang Shirai, Kotaro Animals Neodymium Gastropoda Australia Isotopes Animal Shells Owing to their precision and predictability, radiogenic isotopes are prized for tracking the movement of terrestrial and freshwater species, as well as the origins of natural products. Yet, their use in marine systems is rare. Here, we investigate neodymium (Nd) isotope ratios, a radiogenic isotope system that is rarely used in biology but has characteristics that make it useful for marine biological applications. Nd isotope ratios are influenced by continental geology; as such, we analysed 143Nd/144Nd or ƐNd in 112 gastropod shells (abalone) collected from 11 geologically diverse sites in southern Australia. We found strong spatial differences in isotope ratios, which ranged from -18.2 ƐNd in the west of Australia to -3.4 ƐNd in the east. Such differences can be broadly linked to exposed continental rock age-a trend that was also apparent when comparing our data to published ƐNd data from northeast Asia. This study represents, to our knowledge, the largest analysis of ƐNd in modern biological material and provides insight into spatial trends and its usefulness as a radiogenic marker. Our findings highlight the exciting potential of ƐNd as a tool for biologists to understand marine animal movement and the origins of marine products. |
