Abstract

This review examines recent developments in the application of stable isotope analyses (δ¹⁸O, δ¹³C, δ¹⁵N, δD) to lacustrine invertebrate remains. These remains are ubiquitous in lacustrine sediments and thus provide an opportunity to measure changes in stable isotope ratios across a range of timescales and environments and allow interpretive power beyond taxonomic studies. To date they have been relatively understudied in comparison to carbonate fossils and offer both opportunities and challenges and we explore both themes in this review. This review will explore improvements to analytical instrumentation and the opportunities that this presents, it will look at a range of new studies of the modern lacustrine environment and how these studies allow a more nuanced palaeoenvironmental approach. We review recent studies that have used these advancements in understanding to help to reveal new knowledge of past climates, environments and ecology. In addition, we explore new studies that help to elucidate the role of methane-derived carbon to lacustrine food webs and the drivers behind this, including new data to estimate the contribution of methane derived carbon to an arctic lake. We conclude that major progress is currently being made in invertebrate-isotope analyses, and we expect this to continue apace.

湖沼壳质无脊椎动物遗骸的稳定同位素分析：分析进展、挑战和潜力

本综述探讨了将稳定同位素分析（δ18O、δ13C、δ15N、δD）应用于湖泊无脊椎动物遗骸的最新进展。这些遗骸在湖沼沉积物中无处不在，因此提供了一个测量稳定同位素比值在不同时间尺度和环境中变化的机会，并使解释能力超越了分类研究。迄今为止，与碳酸盐化石相比，对它们的研究相对不足，这既是机遇也是挑战，我们将在本综述中探讨这两个主题。本综述将探讨分析仪器的改进以及由此带来的机遇，还将探讨一系列有关现代湖沼环境的新研究，以及这些研究是如何实现更细致的古环境研究方法的。我们将回顾最近的一些研究，这些研究利用这些认识上的进步，帮助揭示有关过去气候、环境和生态的新知识。此外，我们还探讨了有助于阐明甲烷衍生碳对湖泊食物网的作用及其背后驱动因素的新研究，包括估算甲烷衍生碳对北极湖泊贡献的新数据。我们的结论是，目前在无脊椎动物同位素分析方面正在取得重大进展，我们希望这种进展能够继续加快。

期刊介绍： Quaternary Science Reviews caters for all aspects of Quaternary science, and includes, for example, geology, geomorphology, geography, archaeology, soil science, palaeobotany, palaeontology, palaeoclimatology and the full range of applicable dating methods. The dividing line between what constitutes the review paper and one which contains new original data is not easy to establish, so QSR also publishes papers with new data especially if these perform a review function. All the Quaternary sciences are changing rapidly and subject to re-evaluation as the pace of discovery quickens; thus the diverse but comprehensive role of Quaternary Science Reviews keeps readers abreast of the wider issues relating to new developments in the field.
