摘要

亚马逊拥有世界上最丰富的无尾类物种。哥伦比亚亚马逊地区的非法砍伐率最高,导致物种加速消失。本综述的目的是找出有尾目动物研究中的知识不足之处,以便有效地开展保护工作。我们从不同的数据库中进行了系统的文献检索。为此,我们对已发表文献中的知识缺口进行了评估,以确定信息缺乏的领域,旨在解决对促进科学理解和为有效的保护和管理策略提供信息至关重要的关键主题。我们按照 PRISMA(系统综述和 Meta 分析首选报告项目)协议阅读了每篇文献的、方法、研究领域、结果和补充材料。我们发现了 161 篇文献,最早的出版物可追溯到 20 世纪 40 年代,2000 年以后的产量最高。随着时间的推移,研究主题的多样性也在增加。研究最多的主题是系统学和分类学、自然史、地理分布,而研究最少的主题(少于六篇文献)是细胞生物学和微生物学、遗传学、毒理学、民族生物学、饮食、传染病、生物地理学和宏观生态学。在这些代表性不足的领域仍需进一步研究。只有 10 个物种在 17 篇以上的论文中出现,165 个物种在不到 3 篇的论文中出现。只有 3 个物种(Allobates femoralis、Dendropsophus parviceps 和 Phyllomedusa bicolor)在 10 个以上的主题中得到研究,而且一般来说,研究集中在成体生命阶段,对幼体阶段的了解仍是空白(海克尔缺陷)。我们在已发表的文献中发现了 296 种无脊椎动物;亚马孙省、卡克塔省和普图马约省的研究数量最多,而梅塔省、维查达省、纳里尼奥省和考卡省的知识缺口很大。收集原始野外数据和利用生物标本进行研究的情况显著增加,这两个时期分别有 30.6% 和 40% 的研究依赖于这些数据来源。然而,在整个 76 年间,只有一篇出版物对无尾类动物进行了实验研究,这凸显了生态生理学研究的严重不足。我们的综述没有发现一篇包含详细人口统计数据或生命表的种群生态学论文(普雷斯顿的不足),不过我们确实发现了六篇报告七个物种丰度数据的论文,这些数据可用于保护工作。我们发现有两篇论文报告了功能特征,如繁殖模式和形态特征(Raunkiæran 缺失);但我们没有发现一篇关于生物相互作用(Eltonian 缺失)、物种的非生物耐受性(Hutchinson 缺失)或明确的进化模式(达尔文缺失)的论文。哥伦比亚无脊椎动物和爬行动物名录》(Catálogo de Anfibios y Reptiles de Colombia)中只收录了 5 个无脊椎动物物种,BioModelos 在线平台上只有 2 个物种的分布模型可用于绘制哥伦比亚物种分布图(华莱士式不足)。在 296 种无脊椎动物中,有 32 种被归入世界自然保护联盟(IUCN)的各种威胁类别,但由于缺乏种群趋势信息,这些评估仅基于地理分布数据(AOO 和 EOO),结果有 218 种因分布广泛而被归类为最不需要保护的物种。这项研究强调了哥伦比亚亚马逊地区对有尾目动物种群生态学的关注有限,尽管它在了解人口统计过程和物种保护方面起着至关重要的作用。亚马逊地区的爬行动物学研究必须侧重于为物种保护提供以下关键信息:(a)在成熟的原始森林中进行长期的参与式种群评估;(b)检测物种的丰度和功能特征价值随景观人为改造而发生的变化;(c)开发和验证亚马逊地区的物种分布图。通过开放式平台共享原始的无脊椎动物物种数量和分布数据,是为该地区制定知情保护战略的关键步骤。这些数据能够及早发现栖息地退化和丧失的影响,并为长期参与性监测有尾类物种及其栖息地制定了研究议程。

Major knowledge shortfalls for Colombian Amazonian anurans: Implications for conservation

Major knowledge shortfalls for Colombian Amazonian anurans: Implications for conservation

The Amazon boasts the highest anuran species diversity in the world. The Colombian Amazon has the highest rates of illegal deforestation, leading to accelerated species loss. The objective of this review was to identify knowledge shortfalls in anuran research to effectively address conservation efforts. We conducted a systematic literature search from different databases. To this end, we evaluated knowledge gaps in the published literature to pinpoint areas where information is lacking, aiming to address critical topics essential for advancing scientific understanding and informing effective conservation and management strategies. We read the Abstract, Methods, Study Area, Results and supplementary material for each document following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) protocol. We found 161 documents, with the earliest publications dating back to the 1940s, and the highest productivity occurring since 2000. The diversity of research topics has increased over time. The most studied topics were systematics and taxonomy, natural history, geographic distributions, while the least studied topics (with less than six documents) were cell biology and microbiology, genetics, toxicology, ethnobiology, diet, infectious diseases, biogeography and macroecology. There remains a need for further research in these underrepresented areas. Only 10 species were represented in more than 17 papers and 165 species were represented in less than three publications. Only three species (Allobates femoralis, Dendropsophus parviceps and Phyllomedusa bicolor) were studied from more than 10 topics and, in general, the studies concentrated on adult life stages, maintaining a gap in the knowledge of larval stages (Haeckelian shortfall). We found 296 anuran species reported in the published documents; and the departments of Amazonas, Caquetá and Putumayo had the highest number of studies with great knowledge gaps in Meta, Vichada, Nariño and Cauca. There was an important increase in the collection of primary field data, and the use of biological collections for specimen studies, with 30.6% and 40% of total studies in these periods, respectively, relying on these data sources. However, in the entire 76-year span, there has been only one publication that conducted experiments on anurans, highlighting the considerable lack of eco-physiological studies. Our review did not find a population ecology paper with detailed demographic data or life tables (Prestonian shortfall), although we did uncover six papers reporting abundance data of seven species that could be applied to conservation efforts. We found two papers that reported on functional traits such as reproductive modes and morphological traits (Raunkiæran shortfall); but we did not find a paper on biotic interactions (Eltonian shortfall), species'abiotic tolerances (Hutchinsonian shortfall), or explicit evolutionary patterns (Darwinian shortfall). Only five anuran species were listed in the “Catálogo de Anfibios y Reptiles de Colombia” and only two species have distribution models available on the BioModelos online platform to map Colombian species distribution (Wallacean shortfall). Of the 296 anuran species, 32 are classified under various IUCN threat categories, although these assessments were based solely on geographical distribution data (AOO and EOO) due to the lack of population trend information, resulting in 218 species categorized as of least conservation concern, due to their wide distribution. This study highlights the limited focus on anuran population ecology in the Colombian Amazon, despite its critical role in understanding demographic processes and species conservation. Herpetological research in the Amazon must focus on providing the following critical information for species conservation: (a) long-term participatory population assessments in mature native forests, (b) detection of changes in the abundance and value of species' functional traits in response to landscape anthropogenic transformation and (c) the development and validation of species distribution maps for the Amazonian region. Sharing raw anuran species population and distribution data through open-access platforms are crucial steps for the development of informed conservation strategies for the region. Such data enable early detection of habitat degradation and loss effects and establishes a research agenda for long-term participatory monitoring of anuran species and their habitats.

期刊介绍: Austral Ecology is the premier journal for basic and applied ecology in the Southern Hemisphere. As the official Journal of The Ecological Society of Australia (ESA), Austral Ecology addresses the commonality between ecosystems in Australia and many parts of southern Africa, South America, New Zealand and Oceania. For example many species in the unique biotas of these regions share common Gondwana ancestors. ESA''s aim is to publish innovative research to encourage the sharing of information and experiences that enrich the understanding of the ecology of the Southern Hemisphere. Austral Ecology involves an editorial board with representatives from Australia, South Africa, New Zealand, Brazil and Argentina. These representatives provide expert opinions, access to qualified reviewers and act as a focus for attracting a wide range of contributions from countries across the region. Austral Ecology publishes original papers describing experimental, observational or theoretical studies on terrestrial, marine or freshwater systems, which are considered without taxonomic bias. Special thematic issues are published regularly, including symposia on the ecology of estuaries and soft sediment habitats, freshwater systems and coral reef fish.
