Over the last four decades much progress has been made towards recognising causes of global amphibian declines, but knowledge of fine scale drivers, particularly for specialised species, remains poor, inhibiting conservation effectiveness. The case of the Table Mountain Ghost frog (Heleophryne rosei) provides an example of this, listed as Critically Endangered for the last 15 years with limited conservation actions identified due to a lack of information about threat mechanisms and magnitude of declines. To address this, we investigated H. rosei tadpole occupancy dynamics over three years in stream pools on Table Mountain in Cape Town, South Africa, the only locality where this species occurs. Tadpole spatiotemporal distribution was examined as a function of abiotic and biotic factors to quantify habitat requirements, rank threats, and identify conservation actions. Heleophryne rosei tadpole occupancy was negatively correlated with levels of fine sediments (silt and sand), which embed larger substrates and decrease the diversity of benthic microhabitat. Increased abundance of these fine sediments was also associated with higher extinction probabilities. Localised habitat degradation from hiking paths, alien vegetation, and flow manipulation were identified as the primary threats to this species, increasing the sources of fine sediments and inhibiting the fluvial systems ability to effectively flush these sediments out. Our results demonstrate the importance of pore space refugia for mountain headwater stream-adapted amphibians and provides the required data to inform management decisions for this Critically Endangered species.
过去四十年来，在认识全球两栖动物减少的原因方面取得了很大进展，但对细微驱动因素的了解，尤其是对特殊物种的了解仍然不足，阻碍了保护工作的有效性。桌山幽灵蛙（Heleophryne rosei）就是一个很好的例子，在过去的 15 年中，它一直被列为极度濒危物种，但由于缺乏有关威胁机制和衰退程度的信息，确定的保护行动非常有限。为了解决这个问题，我们在南非开普敦桌山的溪流水池（该物种唯一的分布区）中调查了三年来 H. rosei 蝌蚪的栖息动态。我们将蝌蚪的时空分布作为非生物和生物因素的函数进行了研究，以量化栖息地要求、对威胁进行排序并确定保护措施。Heleophryne rosei蝌蚪的占有率与细沉积物（淤泥和沙子）的含量呈负相关，细沉积物会嵌入较大的基质，降低底栖微生境的多样性。这些细沉积物含量的增加也与更高的灭绝概率有关。徒步路径、外来植被和水流操纵造成的局部栖息地退化被认为是该物种面临的主要威胁，它们增加了细沉积物的来源，抑制了河川系统有效冲刷这些沉积物的能力。我们的研究结果证明了孔隙空间避难所对适应山地溪流的两栖动物的重要性，并为这一极度濒危物种的管理决策提供了所需数据。

For all species, causes of mortality, both anthropogenic and natural, should be recorded. In Critically Endangered species these records are even more important, owing to their potential impacts on small and/or declining populations. Here we present a case of natural mortality that occurred when a 20-day old Hooded Vulture nestling fell from its nest in Limpopo province, South Africa, which is a new cause of mortality for the Critically Endangered Hooded Vulture Necrosyrtes monachus throughout its range. We also compile all known causes of mortality for Hooded Vultures from the scientific and grey literature. The carcass of this nestling was found on the ground below the nest some 25 days later. This cause of mortality is previously undocumented for this vulture species, and it was recorded on a series of photographs taken by a camera trap in the nest tree. We believe this cause of mortality to be uncommon when compared to other threats faced by this species.

Environmental DNA metabarcoding (eDNA) is a rapidly emerging field in which high-throughput sequencing is used to catalogue the biodiversity of ecosystems through the amplification of DNA extracted from environmental samples (water, air, faeces and soil). Although eDNA has strong links to DNA barcoding, the molecular marker most often used to detect vertebrates in eDNA studies is a portion of the mitochondrial 12S ribosomal RNA (12S rRNA) and not the standard cytochrome oxidase I (COI) marker used in traditional DNA barcoding. eDNA methods rely on a comprehensive reference library to link sequence data to species, which are often lacking in hyper-diverse countries such as South Africa. In this study, we review the present state of DNA barcode reference databases for both 12S rRNA and COI for freshwater fish (native and introduced) found in South African aquatic systems. Analysis of DNA records available on GenBank and the Barcode of Life Database (BOLD) revealed incomplete records of the examined taxa for both markers. Our findings showed that 34 species, 6 genera and 0 families of native South African freshwater fish lack COI barcode records, while 86 species, 22 genera and 8 families lack 12S rRNA records. Unlike the native freshwater fish, the non-native fish all had barcode records available for both COI and 12S rRNA. Producing comprehensive reference libraries for both markers is an important first step in developing an eDNA protocol for the non-invasive monitoring of native and non-native freshwater fish in South Africa.
环境 DNA 代谢编码（eDNA）是一个迅速崛起的领域，通过对从环境样本（水、空气、粪便和土壤）中提取的 DNA 进行扩增，利用高通量测序对生态系统的生物多样性进行编目。虽然 eDNA 与 DNA 条形码有密切联系，但在 eDNA 研究中最常用于检测脊椎动物的分子标记是线粒体 12S 核糖体 RNA（12S rRNA）的一部分，而不是传统 DNA 条形码中使用的标准细胞色素氧化酶 I（COI）标记。在本研究中，我们回顾了南非水生系统中淡水鱼类（本地和引进）12S rRNA 和 COI 的 DNA 条形码参考数据库的现状。对 GenBank 和生命条形码数据库（BOLD）中的 DNA 记录进行分析后发现，所研究类群的这两种标记的记录都不完整。我们的研究结果表明，南非本地淡水鱼中有 34 种、6 属和 0 科缺少 COI 条形码记录，86 种、22 属和 8 科缺少 12S rRNA 记录。与本地淡水鱼不同，非本地鱼类都有 COI 和 12S rRNA 的条形码记录。为这两种标记建立全面的参考文献库，是为南非本地和非本地淡水鱼类的非侵入性监测制定 eDNA 协议的重要第一步。

AbstractThe genus Equus comprises six species and 22 subspecies. Ethiopia is the only country in the world that has all three surviving species of zebra. The population status, structure, and seasonal range of Grevy’s zebra (Equus grevyi) were studied in the Hallaydeghe Asebot Protected Area (HAPA), southeast Ethiopia, using line transects and silent detection methods. Data were collected from 2021 to 2022 covering both the wet and dry seasons. The seasonal range of Grevy’s zebra was studied using the minimum convex polygon method. We counted 89 and 61 Grevy’s zebra during the wet and dry seasons, respectively. The total population size was estimated to be 75 individuals with a 95% confidence interval of 60–90 individuals. The adult to sub-adult ratio was 3.1:1.0 during the wet season and 4:1 during the dry season. The sex ratio of adult female to adult male was 5:1 during the wet season and 4:1 during the dry season. The seasonal range of the species in the HAPA was 477 km2 (n = 89) during the wet season and 711 km2 (n = 61) during the dry season. During the dry season Grevy’s zebra move out of the protected area to the Blen hot spring and its associated wetlands for green grazing and water. Hence, further study is needed on the possibility of incorporating the Blen hot spring and its associated wetlands into the protected area to promote the sustainable conservation of the species in the HAPA.Keywords: age structureanimal movementconservationzebra populationsprotected areaseasonssex structure
摘要马属有6种22亚种。埃塞俄比亚是世界上唯一一个拥有所有三种斑马的国家。采用样线法和无声检测法对埃塞俄比亚东南部Hallaydeghe Asebot保护区(HAPA)的灰斑斑马(Equus grevyi)种群状况、种群结构和季节分布进行了研究。数据收集于2021年至2022年，涵盖旱季和雨季。采用最小凸多边形法研究了灰斑斑马的季节变化范围。在旱季和雨季，我们分别统计了89头和61头灰斑斑马。总种群规模估计为75只，95%置信区间为60-90只。湿季成虫与亚成虫的比值为3.1:1.0，旱季为4:1。雨季成虫雌雄性别比为5:1，旱季为4:1。HAPA物种的季节分布范围在雨季为477 km2 (n = 89)，在旱季为711 km2 (n = 61)。在旱季，灰斑斑马从保护区迁移到Blen温泉及其相关的湿地，以获得绿色放牧和水。因此，需要进一步研究将勃伦温泉及其伴生湿地纳入保护区的可能性，以促进HAPA中物种的可持续保护。关键词:年龄结构动物运动保护斑马种群保护区季节性别结构

AbstractGomphocerinae grasshoppers (Orthoptera: Acrididae) are generally characterised by their polymorphism and cryptic diversity, which can be confusing when relying on morphological identification alone. DNA taxonomy serves as a powerful molecular tool for species identification and biodiversity assessment. In the context of zoogeography and the biodiversity conservation of animal resources in ecosystems, DNA barcoding data for Algerian Gomphocerinae fauna remains limited in global databases, despite their agroeconomic and environmental importance. Therefore, in this study, we collected various species of this subfamily from the Biskra region in Algeria and conducted DNA barcoding analysis, employing different molecular species delimitation methods (the automatic barcode gap discovery, assemble species by automatic partitioning, single-threshold general mixed Yule coalescent model, Bayesian Poisson tree process and multi-rate Poisson tree process methods), as well as phylogenetic analyses (maximum-likelihood and Bayesian inference) based on two molecular markers (COI and ITS). The results of the 163 newly generated sequences demonstrated that DNA barcoding technology is highly efficient and valuable for species identification in the subfamily Gomphocerinae, showing strong congruence with morphological evidence for 12 species, including eight species that were sequenced for the first time. This study also reported a new record of the genus Stenohippus Uvarov, 1926 in Algeria, comprising two species. Additionally, taxonomic revision allowed the species Dociostaurus biskrensis Moussi & Petit, 2014, to be transferred to the genus Stenohippus. Molecular tree analyses revealed the phylogenetic positions of the newly sequenced species within the subfamily Gomphocerinae and provided insights into their evolutionary relationships. These new data serve as a starting point for future research in other geographical areas, enabling a better understanding of the biodiversity of this insect group in Algeria.Keywords: BiskraCOI and ITSDNA barcodingmolecular taxonomynew recordStenohippus
