Bats are a diverse and ecologically important group of mammals that play critical roles in ecosystems. Accurate identification is necessary to comprehend bat species' ecology and behavior to further the conservation of bats. Both phenotypic and genotypic methods have been used for bat identification, but their relative effectiveness remains unclear in the Afrotropics. This study compared the advantages and limitations of phenotypic and genotypic identification of bats to improve and ensure effective bat species identification. Bats were captured using mist nets within protected and unprotected areas in different vegetation zones in Nigeria. Morphological identification of all captured bats was done using the guide, Mammals of Africa. Genotypic identification was done by extracting genomic DNA and Sanger sequencing of the generated mtDNA PCR amplicons. We then compared the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the phenotypic to the genotypic outcomes of our identification. We trapped 91 bats, and the phenotypic identification of 90 individual species showed sensitivity ranges between 68% and 100%, except for spp., whose sensitivity was low (14%). The specificity was generally good for all species > 96%. Phenotypic identification is accurate and reliable for most trapped bat species (, spp., , spp., , and spp.). However, phenotypic identification reveals its limitations in some bat species such as and spp., which had more variable results from their genetic characterization. and had no distinct genetic differentiation in their mtDNA. This highlights the importance of using multiple methods for bat identification to ensure the most accurate results.
蝙蝠是一类多样且在生态系统中具有重要意义的哺乳动物,在生态系统中发挥着关键作用。准确识别对于理解蝙蝠物种的生态和行为以促进蝙蝠保护至关重要。表型和基因型方法都已用于蝙蝠识别,但在非洲热带地区,它们的相对有效性仍不明确。本研究比较了蝙蝠表型和基因型识别的优缺点,以改进并确保有效地识别蝙蝠物种。在尼日利亚不同植被区的保护区和非保护区内,使用雾网捕获蝙蝠。所有捕获蝙蝠的形态学识别依据《非洲哺乳动物》指南进行。基因型识别通过提取基因组DNA并对生成的线粒体DNA聚合酶链式反应扩增子进行桑格测序来完成。然后,我们将表型识别的敏感性、特异性、阳性预测值(PPV)和阴性预测值(NPV)与我们识别的基因型结果进行了比较。我们捕获了91只蝙蝠,对90个个体物种的表型识别显示,除了 属蝙蝠,其敏感性较低(14%)外,敏感性范围在68%至100%之间。所有物种的特异性总体良好,均>96%。对于大多数捕获的蝙蝠物种( 属、 属、 属、 属、 属和 属),表型识别准确可靠。然而,表型识别在某些蝙蝠物种中显示出其局限性,例如 属和 属蝙蝠,它们的遗传特征结果变化更大。 属和 属在其线粒体DNA中没有明显的遗传分化。这凸显了使用多种方法进行蝙蝠识别以确保获得最准确结果的重要性。
