Wilder B. T., Becker A. T., Dettman D. L., Marine subsidies produce cactus forests on desert islands, Scientific Reports, 2022, 12:17110, doi: 10.1038/s41598-022-21133-3
Stable nitrogen isotope measurements trace links between fish, seabirds, guano, soil and Pachycereus pringlei tissues. Comparisons among seabird islands, other islands and mainland sites reveal contrasting nitrogen isotope signatures. The paper examines marine nutrient inputs into desert cactus forests.
