Abstract

Cryptic species are groups of two or more taxa that were previously classified as single nominal species. Being almost morphologically indistinguishable, cryptic species have historically been hard to detect. Only through modern morphometric, genetic, and molecular analyses has the hidden biodiversity of cryptic species complexes been revealed. Cryptic diversity is now widely acknowledged, but unlike more recognisable, charismatic species, scientists face additional challenges when studying cryptic taxa and protecting their wild populations. Demographical and ecological data are vital to facilitate and inform successful conservation actions, particularly at the individual species level, yet this information is lacking for many cryptic species due to their recent taxonomic description and lack of research attention. The first part of this article summarises cryptic speciation and diversity, and explores the numerous barriers and considerations that conservation biologists must navigate to detect, study and manage cryptic species populations effectively. The second part of the article seeks to address how we can overcome the challenges associated with efficiently and non-invasively detecting cryptic species in-situ, and filling vital knowledge gaps that are currently inhibiting applied conservation. The final section discusses future directions, and suggests that large-scale, holistic, and collaborative approaches that build upon successful existing applications will be vital for cryptic species conservation. This article also acknowledges that sufficient data to implement effective species-specific conservation will be difficult to attain for many cryptic animals, and protected area networks will be vital for their conservation in the short term.

隐蔽物种保护:综述。
隐蔽物种是由两个或更多分类群组成的群体,这些分类群以前被归类为单一的标称物种。由于在形态上几乎无法区分,隐蔽物种历来很难被发现。只有通过现代形态计量学、遗传学和分子分析,隐性物种群隐藏的生物多样性才得以揭示。隐性多样性现在已得到广泛承认,但与更易识别、更有魅力的物种不同,科学家在研究隐性类群和保护其野生种群时面临更多挑战。人口学和生态学数据对于促进和指导成功的保护行动至关重要,尤其是在物种个体层面,但由于许多隐生物种的分类学描述较新,且缺乏研究关注,因此这些信息非常缺乏。本文第一部分概述了隐生物种的分化和多样性,并探讨了保护生物学家在有效探测、研究和管理隐生物种种群时必须克服的众多障碍和考虑因素。文章的第二部分试图探讨我们如何才能克服与高效、无创地就地探测隐生物种相关的挑战,并填补目前阻碍应用保护的重要知识空白。最后一部分讨论了未来的发展方向,并提出以现有成功应用为基础的大规模、整体性和协作性方法对隐栖物种保护至关重要。本文还承认,对于许多隐栖动物来说,很难获得足够的数据来实施有效的特定物种保护,保护区网络在短期内对其保护至关重要。

期刊介绍: Biological Reviews is a scientific journal that covers a wide range of topics in the biological sciences. It publishes several review articles per issue, which are aimed at both non-specialist biologists and researchers in the field. The articles are scholarly and include extensive bibliographies. Authors are instructed to be aware of the diverse readership and write their articles accordingly. The reviews in Biological Reviews serve as comprehensive introductions to specific fields, presenting the current state of the art and highlighting gaps in knowledge. Each article can be up to 20,000 words long and includes an abstract, a thorough introduction, and a statement of conclusions. The journal focuses on publishing synthetic reviews, which are based on existing literature and address important biological questions. These reviews are interesting to a broad readership and are timely, often related to fast-moving fields or new discoveries. A key aspect of a synthetic review is that it goes beyond simply compiling information and instead analyzes the collected data to create a new theoretical or conceptual framework that can significantly impact the field. Biological Reviews is abstracted and indexed in various databases, including Abstracts on Hygiene & Communicable Diseases, Academic Search, AgBiotech News & Information, AgBiotechNet, AGRICOLA Database, GeoRef, Global Health, SCOPUS, Weed Abstracts, and Reaction Citation Index, among others.
