Abstract

Terrestrial and semi-aquatic mammals are facing increasing threats globally, highlighting the need for reliable data on species' occurrence, distribution, and abundance for effective conservation efforts. However, obtaining reliable and robust information over broad spatial and temporal scales remains a significant challenge.
Environmental DNA (eDNA) and invertebrate-derived DNA (iDNA) applications have emerged as powerful surveying methods, with the potential to revolutionise ecological monitoring by improving species detections and providing better insights into mammalian distribution and diversity. While eDNA relies on genetic material shed by species into their surroundings, iDNA leverages DNA from invertebrates that interact with mammals. Both approaches offer a cost-effective means to obtain species records and community diversity metrics.
This review explores global applications of e/iDNA for surveying terrestrial and semi-aquatic mammals. By providing a comprehensive overview of the applications, sampling design, challenges, and prospects, this review serves as a guide to researchers and conservationists seeking to use eDNA for mammalian conservation efforts.
By evaluating the current state of e/iDNA applications, this review identifies the challenges and milestones that need to be addressed for these methods to become a practical method for monitoring mammals on a global scale. It highlights the need for further research to enhance the sensitivity and reliability of e/iDNA detections, standardisation of methodologies, and validation through comparison with traditional monitoring methods. This review sheds light on the potential of e/iDNA as valuable tools for aiding mammal conservation and inspiring future research and advancements in this field.

从水到陆：环境DNA和无脊椎动物来源DNA在陆生和半水生哺乳动物监测中的应用综述

陆生和半水生哺乳动物在全球范围内面临着越来越多的威胁，这凸显了对物种发生、分布和丰度的可靠数据的需求，以进行有效的保护工作。然而，在广泛的空间和时间尺度上获得可靠和可靠的信息仍然是一个重大挑战。环境DNA （eDNA）和无脊椎动物衍生DNA （iDNA）的应用已经成为一种强大的测量方法，有可能通过改进物种检测和更好地了解哺乳动物的分布和多样性来彻底改变生态监测。虽然eDNA依赖于物种传播到周围环境的遗传物质，但iDNA利用了与哺乳动物相互作用的无脊椎动物的DNA。这两种方法都是获得物种记录和群落多样性指标的一种经济有效的方法。本文综述了e/iDNA在陆地和半水生哺乳动物调查中的全球应用。通过对应用、采样设计、挑战和前景的全面概述，本综述可作为研究人员和保护主义者寻求使用eDNA进行哺乳动物保护工作的指南。通过评估e/iDNA应用的现状，本综述确定了这些方法要成为全球范围内监测哺乳动物的实用方法需要解决的挑战和里程碑。它强调需要进一步研究以提高e/iDNA检测的灵敏度和可靠性，方法的标准化，并通过与传统监测方法的比较进行验证。这一综述揭示了e/iDNA作为帮助哺乳动物保护的有价值工具的潜力，并启发了该领域未来的研究和进展。

期刊介绍： Mammal Review is the official scientific periodical of the Mammal Society, and covers all aspects of mammalian biology and ecology, including behavioural ecology, biogeography, conservation, ecology, ethology, evolution, genetics, human ecology, management, morphology, and taxonomy. We publish Reviews drawing together information from various sources in the public domain for a new synthesis or analysis of mammalian biology; Predictive Reviews using quantitative models to provide insights into mammalian biology; Perspectives presenting original views on any aspect of mammalian biology; Comments in response to papers published in Mammal Review; and Short Communications describing new findings or methods in mammalian biology.
