SummaryThe Hkakabo Razi region located in northern Myanmar is an Important Bird Area and part of the Eastern Himalayan Biodiversity Hotspot. Within the framework of the World Heritage Convention to enlist the site under criterion (ix) and (x), we conducted a biodiversity assessment for passerine birds using DNA barcoding and other molecular markers. Of the 441 bird species recorded, we chose 16 target species for a comparative phylogeographic study. Genetic analysis was performed for a larger number of species and helped identifying misidentified species. We found phylogeographic structure in all but one of the 16 study species. In 13 species, populations from northern Myanmar were genetically distinctive and local mitochondrial lineages differed from those found in adjacent regions by 3.9–9.9% uncorrected genetic distances (cytochrome-b). Since the genetic distinctiveness of study populations will be corroborated by further differences in morphology and song as in other South-East Asian passerines, many of them will be candidates for taxonomic splits, or in case an older taxon name is not available, for the scientific description of new taxa. Considering the short time frame of our study we predict that a great part of undetected faunal diversity in the Hkakabo Razi region will be discovered.

缅甸北部 Hkakabo Razi 雀形目鸟类的生物多样性评估——对分子遗传学保护的意义

摘要位于缅甸北部的 Hkakabo Razi 地区是重要的鸟类区，也是喜马拉雅东部生物多样性热点的一部分。在世界遗产公约的框架内，根据标准 (ix) 和 (x) 将遗址列入名单，我们使用 DNA 条形码和其他分子标记对雀形目鸟类进行了生物多样性评估。在记录的 441 种鸟类中，我们选择了 16 种目标物种进行比较系统地理学研究。对大量物种进行了遗传分析，有助于识别错误识别的物种。除了 16 个研究物种中的一个，我们在所有物种中都发现了系统地理结构。在 13 个物种中，来自缅甸北部的种群在遗传上具有独特性，当地线粒体谱系与邻近地区发现的线粒体谱系相差 3.9-9.9% 未校正的遗传距离（细胞色素-b）。由于研究种群的遗传独特性将通过形态和歌声的进一步差异得到证实，就像其他东南亚雀形目一样，它们中的许多将成为分类分裂的候选者，或者如果没有更早的分类名称，对于科学新分类群的描述。考虑到我们研究的时间很短，我们预测将在 Hkakabo Razi 地区发现很大一部分未被发现的动物多样性。
