The measurement of naturally occurring stable isotope ratios of the light elements (C, N, H, O, S) in animal tissues and associated organic and inorganic fractions of associated environments holds immense potential as a means of addressing effects of global change on animals. This paper provides a brief review of studies that have used the isotope approach to evaluate changes in diet, isotopic niche, contaminant burden, reproductive and nutritional investment, invasive species and shifts in migration origin or destination with clear links to evaluating effects of global change. This field has now reached a level of maturity that is impressive but generally underappreciated and involves technical as well as statistical advances and access to freely available R-based packages. There is a need for animal ecologists and conservationists to design tissue collection networks that will best answer current and anticipated questions related to the global change and the biodiversity crisis. These developments will move the field of stable isotope ecology toward a more hypothesis driven discipline related to rapidly changing global events.
动物组织及相关环境中轻元素（C、N、H、O、S）自然发生稳定同位素比值的测量在评估全球变化对动物的影响方面具有巨大的潜力。本文简要回顾了利用同位素方法评估饮食变化、同位素生态位、污染物负担、生殖和营养投入、入侵物种以及迁移起源或目的地变化的研究，这些研究与评估全球变化的影响有着明确的联系。该领域目前已经达到了令人印象深刻但普遍未被充分认识的成熟水平，涉及技术和统计方面的进步，以及对免费提供的基于 R 的软件包的访问。动物生态学家和自然资源保护主义者需要设计组织采集网络，以最好地回答与全球变化和生物多样性危机相关的当前和预期问题。这些发展将使稳定同位素生态学领域朝着与快速变化的全球事件相关的更具假设驱动的学科发展。
